Adult Development and Associated Health Risks

Much has been learned about adult development in recent decades. Adults go through stages of development (emerging adulthood, young adulthood, middle adulthood, post-retirement, and very old age) with certain challenges at each stage. Viewing patients through a developmental lens is part of providing patient-centered care. Knowing the prominent issues, stressors, and risks at each stage of development is important in understanding patients. This knowledge can help customize medical advice to patients regarding obesity, disability, sleep, substance use, relationships, and age-related declines. This paper summarizes an updated view of adult development and discusses its relevance to health risks and patient-centered care practices at different stages.

Treatment of Alec: "History does not have to repeat itself"

Treatment of patients with pathological narcissism presents several challenges and there is paucity of published case reports that document meaningful and durable change in patients suffering from this condition. Using descriptive and atheoretical language, this paper presents a treatment of a young man in his transition from young adulthood to middle adulthood while he was negotiating complex residues of his experiences of growing up along with developmental challenges related to work and love. Against the backdrop of these transitions, the patient was working through various aspects of functioning related to pathological narcissism. Initially, given academic pressures and past romantic disappointments, he was confronting issues related to perfectionism, self-criticism, and avoidance. While he was able to move past some of these dynamics and function academically, later challenges related to becoming an independent adult led to a retreat into an avoidant state of futility and pessimism. Working through painful family dynamics related to not being seen and controlled, along with a deepening attachment in therapy as well as confrontation with realities of his life, led him to take steps toward greater independence. Thereafter, his treatment focused on learning from life experiences such as a newly developed career and romantic life, accepting the complexity of self and others, and tolerating disillusionments.

Specific autobiographical memories are a resource for identity strength among mature but not emerging adults

Four studies, three pre-planned on Open Science Framework, with 2296 participants explored the potential role of recollecting autobiographical memories in enhancing the sense of identity. Among emerging adults (college students under age 25), recollecting important autobiographical memories did not strengthen sense of identity. Autobiographical memories failed to strengthen identity among emerging adults despite inducing low self-clarity first; despite attempts to prime self-consistent memories by having emerging adults report their stable self-aspects first; and despite attempts to inspire self-event connections by asking emerging adults to explain how the memories exemplified something enduring about the self. Among mature adults (age 25 and older), recollecting important autobiographical memories strengthened sense of identity. Identity was strengthened regardless of whether mature adults were asked to explain how the memories exemplified something enduring about the self. Differences in types of memories or motivation did not account for the differential effects of recollecting autobiographical memories in identity. In short, mature adults appear to readily use autobiographical memories as a resource for identity in a way that emerging adults have not yet mastered.

Facial expressions in adolescent-parent interactions and mental health: A proof-of-concept study

Parent-child relationships are hotbeds of emotion and play a key role in mental health. The present proof-of-concept study examined facial expressions of emotion during adolescent-parent interactions and links with internalizing mental health symptoms. Neutral, negative, and positive facial expressions were objectively measured in 28 parent-adolescent dyads during three 10-min dyadic interactions. Internalizing mental health symptoms were measured using anxiety and depressive symptom questionnaires. Data were analyzed using actor-partner interdependence modeling. Results revealed that higher levels of (a) adolescents' neutral facial expressions as well as (b) parents' negative facial expressions were associated with higher levels of adolescents' mental health symptoms. Findings did not support a robust link between (c) positive expressions and mental health symptoms. Together, these results demonstrate the utility of facial expressions of emotion during parent-child interactions as behavioral correlates of adolescents' internalizing mental health symptoms, highlight the need for replication with larger samples, and suggest directions for future research.

Psychological wellbeing in adult adoptees: current age and developmental tasks

Introduction

Studies about adult adoptees are normally focused on the differences in adjustment difficulties between them and non-adoptees. However, there has been less research about adoptees' positive and developmental adjustment in adulthood. The aim of this study is to test a model of the mediating role of adoptees' achievement of adulthood tasks in the relationship between current age and psychological wellbeing.

Materials and methods

The sample consisted of 117 adults who were adopted as children by Spanish families. Their current mean age is 28.3 years. Participants underwent an interview and completed Ryff's Psychological WellBeing Scales.

Results

Findings show that current age is directly and negatively related to psychological wellbeing [c' = -0.039, 95% CI (-0.078, -0.001)], and the relationship between these variables is mediated by adoptees' achievement of adulthood tasks [indirect effect = 0.035, 95% CI (.014, 0.059)].

Discussion

The findings support traditional theories about transitioning to adulthood, and adds relevant information about this transition in adoptees. Moreover, this work indicates a new way of assessing adoption success, based on long-term measures and normative variables. Services providers should account for the importance of supporting young people on their life transitions and promoting their wellbeing, especially among those who started from disadvantaged contexts.

Self-worth and developmental outcomes in young adults after pediatric bariatric surgery

OBJECTIVES

Bariatric surgery has emerged as a safe/effective treatment for adolescents with severe obesity; therefore, understanding its impact over the life course is imperative. This study examined self-worth and developmental outcomes during the transition to adulthood (19-24 years old) for youth who underwent surgery as adolescents (13-18 years old) and a nonsurgical group with severe obesity.

METHOD

As part of a prospective and multisite observational study series, adolescents (139 surgical, 83 nonsurgical) were followed for 6 years postsurgery/baseline when they completed height/weight measurements and measures of global self-worth, maturity, and occupational, educational, and social functioning as young adults. Growth curve analysis examined global self-worth change, while regressions were used to compare groups and examine adolescent-reported familial predictors and weight-related correlates for outcomes.

RESULTS

Relative to the nonsurgical group, the surgical group experienced a significant quadratic improvement in self-worth and higher year 6 romantic self-perceptions. For the surgical group only, greater family dysfunction predicted lower young adult self-worth and perceptions of maturity, while higher family connectedness predicted higher self-worth and perceptions of maturity. Greater percent weight loss was associated with higher perceptions of maturity for the surgical group.

CONCLUSIONS

Group difference findings suggest that the impact of surgery was on self-worth and romantic self-perceptions, outcomes linked in the developmental literature to body image. For both groups, functioning appeared similar to population-based findings, suggesting they are meeting "expected" age-salient developmental outcomes. The impact of earlier positive family functioning on self-worth and self-perceptions of maturity may place adolescents on pathways to success.

The age-Related Positivity Effect and Emotion Regulation: Assessing Downstream Affective Outcomes

While substantial literature suggests that positive preferences are in the service of emotion regulation pursuits, little evidence has directly linked positivity "processes" with well-being "outcomes." The current study examined age-related differences in negative gaze preferences and how such preferences are related to subsequent regulatory outcomes. Participants were 79 older adults and 72 younger adults. They first provided a baseline mood assessment, which was followed by a standardized emotional video clip for three minutes during which visual fixation preferences were recorded via an eye tracker. Mood was again assessed after the film, which was followed by a standardized video recovery task, and completion of a recovery mood measure. Older adults fixated less on negative portions of the emotional video clip relative to younger adults, indicative of an age-related positivity effect. The indirect effect of age on mood recovery through fixation was not supported.

Convergent and Discriminant Validity of Retrospective Assessments of the Quality of Childhood Parenting: Prospective Evidence From Infancy to Age 26 Years

Retrospective self-report assessments of adults' childhood experiences with their parents are widely employed in psychological science, but such assessments are rarely validated against actual parenting experiences measured during childhood. Here, we leveraged prospectively acquired data characterizing mother-child and father-child relationship quality using observations, parent reports, and child reports covering infancy through adolescence. At age 26 years, approximately 800 participants completed a retrospective measure of maternal and paternal emotional availability during childhood. Retrospective reports of childhood emotional availability demonstrated weak convergence with composites reflecting prospectively acquired observations (R2s = .01-.05) and parent reports (R2s = .02-.05) of parenting quality. Retrospective parental availability was more strongly associated with prospective assessments of child-reported parenting quality (R2s = .24-.25). However, potential sources of bias (i.e., depressive symptoms and family closeness and cohesiveness at age 26 years) accounted for more variance in retrospective reports (39%-40%) than did prospective measures (26%), suggesting caution when using retrospective reports of childhood caregiving quality as a proxy for prospective data.

From gains to losses: Age-related differences in decisions under risk in a non-monetary gambling task

Lifespan theory suggests a shift from a primary orientation towards attaining gains in young adulthood to preventing losses in older adulthood. The current research tested if this motivational shift is reflected in behavioural and emotional responses to risks in non-monetary gains and losses. Study 1 established in a sample of N = 168 younger (18-30 years) and older adults (65-79 years) that a non-monetary gambling task was experienced similarly by the age groups with respect to arousal and valence of the task, and the willingness to continue playing. In Study 2 (N = 83), differences between young (18-30 years) and older (64-85 years) adults' risk-taking in this non-monetary gambling task with mixed gambles were tested while assessing physiological responses (event-related heart rate change) to gain and loss feedback. Behavioural - but not physiological - results confirm hypotheses derived from a lifespan motivational framework regarding age-differential effects of gains and losses.

Parental Socialization and Its Impact across the Lifespan

Classical studies have found that parental warmth combined with parental strictness is the best parental strategy to promote children's psychosocial development. Nevertheless, a growing set of emergent studies has questioned the benefits of parental strictness. The present study examined parental socialization and its short- and long-term impact on the psychosocial development of adolescents and adult children. The sample consisted of 2150 Spanish participants, 623 adolescents (12-18 years), 619 young adults (19-35 years), 502 middle-aged adults (35-59 years), and 406 older adults (60 years or older). Families were classified into one of four typologies (indulgent, authoritative, authoritarian, and neglectful). Psychosocial development was examined with five indicators (physical and family self-concept, nervousness, empathy, and internalization of social values of benevolence). The results show a common short- and long-term pattern between parenting styles and psychosocial development: the indulgent style equaled or even surpassed the authoritative style, whereas the neglectful and authoritarian styles were associated with low scores. The present findings were discussed by considering the importance of the cultural context in family socialization. Additionally, the long-term impact of parental socialization seems to be crucial, even in adulthood.

Culture and well-being in late adulthood: Theory and evidence

Aging happens to everyone everywhere. At present, however, little is known about whether life-span adult development-and particularly development in late adulthood-is pancultural or culture-bound. Here, we propose that in Western cultural contexts, individuals are encouraged to maintain the active, positive, and independent self. This cultural expectation continues even in late adulthood, thus leading to a mismatch between aspirations to live up to the cultural expectation and the reality of aging. This mismatch is potentially alienating. In contrast, in Asian cultural contexts, a critical task throughout life is to achieve attunement with age-graded social roles. This ideal may be more attainable even in late adulthood. Our review of existent evidence lends support to this analysis. Specifically, in late adulthood, Americans showed a robust psychological bias toward high-arousal positive (vs. negative) emotions. This positivity, however, concealed a somber aspect of aging that manifested itself in more demanding realms of life. Thus, Americans in late adulthood also showed marked declines in certain desirable personality traits (e.g., extraversion and conscientiousness) and some aspects of the meaning in life (e.g., personal growth and purpose in life). None of these effects were apparent among East Asians. The current work underscores a need to extend research on life-span development beyond Western populations.

Charting adult development through (historically changing) daily stress processes

This article views adult development through the lens of daily life experiences and recent historical changes in these experiences. In particular, it examines whether theories that postulate general linear increases in well-being throughout adulthood still hold during times of less prosperity and more uncertainty. Descriptive analyses of the National Study of Daily Experiences chart show how stress in the daily lives of Americans may have changed from the 1990s (N = 1,499) to the 2010s (N = 782). Results revealed that adults in the 2010s reported experiencing stressors on 2% more days than in the 1990s, which translates to an additional week of stressors across a year. Participants in the 2010s also reported that stressors were more severe and posed more risks to future plans and finances and that they experienced more distress. These historical changes were particularly pronounced among middle-aged adults (e.g., proportion of stressor days increased by 19%, and perceived risks to finances and to future plans rose by 61% and 52%, respectively). As a consequence, age-related linear increases in well-being observed from young adulthood to midlife in the 1990s were no longer observed in the 2010s. If further studies continue to replicate our findings, traditional theories of adult well-being that were developed and empirically tested during times of relative economic prosperity may need to be reevaluated in light of the changes in middle adulthood currently observed in this historic period.

Enhancing the "Broaden and Build" Cycle of Attachment Security in Adulthood: From the Laboratory to Relational Contexts and Societal Systems

Attachment theory emphasizes both the importance of the availability of caring, supportive relationship partners, beginning in infancy, for developing a sense of safety and security, and the beneficial effects of this sense of security on psychosocial functioning and physical and mental health. In this article, we briefly review basic concepts of attachment theory, focusing on the core construct of attachment security and present evidence concerning the ways in which this sense can be enhanced in adulthood. Specifically, we review findings from laboratory experiments that have momentarily enhanced the sense of attachment security and examined its effects on emotion regulation, psychological functioning, and prosocial behavior. We then review empirical findings and ideas concerning security enhancement by actual relationship partners, non-human symbolic figures, and societal systems in a wide variety of life domains, such as marital relationships, psychotherapy, education, health and medicine, leadership and management, group interactions, religion, law, and government.

Cultural Values, Social Status, and Chinese American Immigrant Parents' Emotional Expressivity

Cultural values and social status are two salient factors in the psychological experiences of immigrant families, and both have been associated with immigrant parents' patterns of emotional expression in previous studies. The present study examined how endorsement of cultural values (collectivism and conformity) and social status were uniquely associated with immigrant parents' emotional expressivity in the family. First-generation Chinese American immigrant parents (N = 239, 80% mothers; M = 41.31 years old) of elementary-age children reported on their endorsement of values of collectivism and conformity, their patterns of emotional expressivity in the family context, and their family income and education levels. Path analyses indicated unique positive associations between family income and all domains of parents' emotional expressivity and negative associations between family income and parents' endorsement of collectivism and conformity. Parents' endorsement of collectivism was negatively associated with negative-dominant expressivity. We discuss implications of our findings for theories of culture and emotion, as well as for future intersectional approaches with Asian American populations.

Raising Children with Poor School Performance: Parenting Styles and Short- and Long-Term Consequences for Adolescent and Adult Development

This study examines the correlates of authoritative (warmth and strictness), indulgent (warmth but not strictness), authoritarian (strictness but not warmth), and neglectful (neither warmth nor strictness) parenting with short- and long-term socialization outcomes in adolescents and adults, with and without poor school performance during adolescence. Short- and long-term socialization outcomes were captured by multidimensional self-esteem (academic/professional, emotional, and family), psychological maturity (self-competence, social competence, and empathy), and emotional maladjustment (nervousness, emotional instability, and hostility). Participants (1195 female and 874 male) consisted of a community sample of adolescents (n = 602), young adults (n = 610), middle-aged adults (n = 469) and older adults (n = 388). Design was a 4 × 3 × 2 × 4 MANOVA (parenting style × school performance × sex × age). Results indicated that the relationship between parenting styles and children’s socialization outcomes does not vary as a function of school performance. The link between parenting styles and socialization outcomes shares a common short- and long- term pattern in adolescents and adults: Indulgent parenting was related to equal or even better socialization outcomes than authoritative parenting, whereas authoritarian and neglectful styles were associated with the worst socialization outcomes.

The Nature of Math Anxiety in Adults: Prevalence and Correlates

It is important to understand the nature of math anxiety in the general adult population, as the importance of math skills does not end when one leaves school. To this end, we present a well-powered, preregistered study of English-speaking U.S. adults describing the nature of math anxiety in this population. 1000 participants were recruited online. Math anxiety was approximately normally distributed, with the mean between "some" and "moderate". Math anxiety was significantly negatively correlated with probability knowledge and math fluency, and significantly positively correlated with general anxiety and test anxiety. Women reported higher math anxiety than did men. Participants who had completed graduate school or had a STEM career had significantly lower levels of math anxiety than did those with less education, or non-STEM careers. Thus, we see evidence for math anxiety in U.S. adults and that it correlates with factors also reported in previous studies using younger and student populations.

Reflections on Aging and Wisdom

The author experienced an unexpected finding over 30 years ago. Despite many losses, older primary care patients had less psychiatric symptomatology than younger patients. This has led to a long learning and teaching focus on the positive relationship between aging and wisdom. Some recent research challenges this relationship. To deal with this challenge the author reflects on two related but complex questions with which he has been struggling. Is there an adaptive value of aging? If wisdom is more likely with aging, why? He concludes that aging is culturally adaptive and that wisdom is aging's individual and societal adaptive strength.

Future Time Perspective: Time Horizons and Beyond

The articles in the present volume enhance the understanding of the role of perceived time in human development. Together, they point to the multifaceted nature of perceived future time and the associations different aspects of time have with goals, preferences, and well-being. Specifically, the articles showcase antecedents and consequences of perceived time left in life, consider ways to optimize measurement of future time horizons, and advance novel questions about the neural correlates of domain-specific aspects of subjective time. Findings are considered within the framework of socioemotional selectivity theory. Future directions for research on time horizons are discussed.

Effort as Person-Focused Praise: "Hard Worker" Has Negative Effects for Adults After a Failure

Although work with children demonstrates a benefit of process-focused praise relative to person-focused praise on post-failure motivation, few studies have examined this result in adults. We tested the effect of three types of praise on adults' post-failure outcomes: person-focused intelligence ("high intelligence"), person-focused effort ("hard worker"), and process-focused effort ("worked hard") in a sample of 156 adults recruited from Amazon's MTurk. Participants completed a set of easy visual pattern recognition problems and were told that they performed better than most adults and were given one of the three types of feedback. They then completed more difficult problems and were told that they had not performed well. Participants in the "hard worker" condition (compared to "worked hard") were more likely to endorse intelligence as a reason for failure. They also reported lower perceived success and less enjoyment than participants in other conditions. Participants in the "high intelligence" condition were more likely to attribute their failure to intelligence than participants in the "worked hard" condition. The results suggest that the benefit of process-focused praise typically found in children (worked hard compared to intelligent) was mostly not replicated in adults, and person-focused effort praise was detrimental in a non-college student adult sample.

Gratitude across the life span: Age differences and links to subjective well-being

Gratitude has been described as an adaptive evolutionary mechanism that is relevant to healthy psychological and interpersonal outcomes. Questions remain as to whether the presence and benefits of gratitude are consistent from young adulthood to old age; prior research has yielded mixed evidence. We examined the magnitude and direction of age differences in gratitude in three samples (combined N = 31,206). We also examined whether gratitude was associated with greater/lesser well-being at different periods in the life course. We found that the experience of gratitude was greatest in older adults and least in middle aged and younger adults. Further, we found that the associations between gratitude and subjective well-being remained relatively constant across the lifespan. Findings are discussed from a developmental perspective.

Aphid Species Affect Foraging Behavior of Coccinella septempunctata (Coccinellidae: Coleoptera)

BACKGROUND

Flowers are admirable in scenic good looks and artistic beautification. These are also playing necessary roles in therapeutic preparations. Aphid is an important sucking pest of various flowers in ornamental territories and it is generally controlled by predators, so it was necessary to evaluate which aphid species affect the predator more or less.

MATERIALS AND METHODS

Biocontrol agent Coccinella septempunctata was used against cosmos aphid (Aphis spiraecola, rose aphid (Macrosiphum rosea), gul e ashrafi aphid (Aphis fabae), kaner aphid (Aphis nerii), chandni aphid (Sitobion avenae), dahlia aphid (Myzus persicae) and annual chrysanthemum aphid (Macrosiphoniella sanborni).

RESULTS

The grub of C. septempunctata consumed 283.8±9.04 M. rosea, 487.7±12.6 M. sanborni, 432.75±16.02 A. spiraecola, 478.2±8.07 A. fabae, 552.3±9.04 M. persicae, 142±1.32 A. nerii and 498.5±13.09 S. avenae in its whole larval life. The M. persicae and M. rosea consuming grubs showed 100% adult emergence while, M. sanborni, A. spiraecola, A. fabae and S. avenae showed 96.58, 89.02, 94.78 and 75.45% adult emergence, respectively.

CONCLUSION

The C. septempunctata has significant predatory potential against A. spiraecola, M. rosea, A. fabae, S. avenae, M. persicae and M. sanborni except A. nerii. Thus, further studies are needed to find out alternate predator to control A. nerii on ornamentals.

Exploring the Possibility of Peak Individualism, Humanity's Existential Crisis, and an Emerging Age of Purpose

There is an emerging cultural narrative in the United States that we are entering an age of purpose—that millennials, more than any other generation, are searching for purpose and purposeful work (Sheahan, 2005) and that we are entering an era or economy of purpose (Hurst, 2014). For profit, non-profit, and educational institutions are perceiving and adapting to serve millennials' demand for purpose in life, specifically within the workplace (Klein et al., 2015). Yet, longitudinal studies of purpose do not exist, and millennials are also referred to as GenMe. Existing quantitative research suggests they (we) are increasingly individualistic, materialistic, and narcissistic (Greenfield, 2013). Google's digitization of millions of books and the Ngram Viewer allow for quantified analysis of culture over the past two centuries. This tool was used to quantitatively test the popular notion that there is a rise in demand for purpose. Analysis reveals a growing interest in purpose-in-life and a shift toward collectivistic values emerging over the lifespan of the millennial generation.

Psychological Well-Being in Italian Families: An Exploratory Approach to the Study of Mental Health Across the Adult Life Span in the Blue Zone

Self-reported measures of psychological well-being and depressive symptoms were examined across differently aged family members, while controlling for the impact of marital status and personal satisfaction about family and non-family relations. Twenty-one grandchildren (i.e., ages 21-36 years) were recruited with their parents (i.e., 48-66 years old) and grandparents (i.e., 75-101 years of age) in the 'blue zone' of Ogliastra, an Italian area known for the longevity of its inhabitants. Each participant was individually presented a battery of questionnaires assessing their lifestyle and several perceived mental health indices, including the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS, Tennant et al., 2007), and the Center for Epidemiologic Studies Depression Scale (i.e., CES-D, Radloff, 1977). After assessing the level of concordance among adults sharing the same context, the Hierarchical Linear Modeling (HLM) approach was used to assess the nested dataset. It was found that family membership (i.e., grandchildren versus parents and grandparents) predicted the WEMWBS score but not the CES-D when the impact of marital status and personal satisfaction about social (i.e., family and non-family) ties was controlled for. Moreover, two separate repeated-measure Analyses of Variance (ANOVAs) documented similar level of personal satisfaction about social relationships across the three family groups. In conclusions, satisfying social ties with friends and family members together with an active socially oriented life style seems to contribute to the promotion of mental health in adult span.

The Mismeasurement of Mind: Life-Span Changes in Paired-Associate-Learning Scores Reflect the "Cost" of Learning, Not Cognitive Decline

The age-related declines observed in scores on paired-associate-learning (PAL) tests are widely taken as support for the idea that human cognitive capacities decline across the life span. In a computational simulation, we showed that the patterns of change in PAL scores are actually predicted by the models that formalize the associative learning process in other areas of behavioral and neuroscientific research. These models also predict that manipulating language exposure can reproduce the experience-related performance differences erroneously attributed to age-related decline in age-matched adults. Consistent with this, results showed that older bilinguals outperformed native speakers in a German PAL test, an advantage that increased with age. These analyses and results show that age-related PAL performance changes reflect the predictable effects of learning on the associability of test items, and indicate that failing to control for these effects is distorting the understanding of cognitive and brain development in adulthood.

The Critique of Regression: The Person, The Field, The Lifespan

The term regression refers to the idea that a person can return to earlier phases of mental development and the primitive modes of functioning associated with them. A core concept in both conflict and deficit models of development, the idea has nonetheless come under increasing scrutiny from critics who argue that it misleads us into a genetic fallacy whereby we reduce the issues of adolescent and adult development to their childhood precursors. Inderbitzen and Levy (2000) suggest that we focus on transformations, or shifts, in mental organization, instead of on regressions. But discarding the concept of regression has theoretical implications: to adopt instead a focus on shifts in mental organization we must (1) consider our object of study to be the meaning-making person, not isolated instincts or needs; (2) understand conscious and unconscious mental life to be embedded in the here-and-now relational field; and (3) adopt a lifespan model of development. The aim here is to outline a theoretical framework in which we can more fully explore the possibility of discarding "regression" in favor of a focus on transformations in the developmental present.

The Genetics of Success: How Single-Nucleotide Polymorphisms Associated With Educational Attainment Relate to Life-Course Development

A previous genome-wide association study (GWAS) of more than 100,000 individuals identified molecular-genetic predictors of educational attainment. We undertook in-depth life-course investigation of the polygenic score derived from this GWAS using the four-decade Dunedin Study (N = 918). There were five main findings. First, polygenic scores predicted adult economic outcomes even after accounting for educational attainments. Second, genes and environments were correlated: Children with higher polygenic scores were born into better-off homes. Third, children's polygenic scores predicted their adult outcomes even when analyses accounted for their social-class origins; social-mobility analysis showed that children with higher polygenic scores were more upwardly mobile than children with lower scores. Fourth, polygenic scores predicted behavior across the life course, from early acquisition of speech and reading skills through geographic mobility and mate choice and on to financial planning for retirement. Fifth, polygenic-score associations were mediated by psychological characteristics, including intelligence, self-control, and interpersonal skill. Effect sizes were small. Factors connecting DNA sequence with life outcomes may provide targets for interventions to promote population-wide positive development.

Stepping Into Retirement: A Postcard From the Threshold

As I begin a postclinical career transition, I pause and describe various early retirement personal, familial, and professional reverberations, as well as some aging-related "long-view" observations about conducting therapy.

Selective Engagement of Cognitive Resources: Motivational Influences on Older Adults' Cognitive Functioning

In this article, I present a framework for understanding the impact of aging-related declines in cognitive resources on functioning. I make the assumption that aging is associated with an increase in the costs of cognitive engagement, as reflected in both the effort required to achieve a specific level of task performance and the associated depletion or fatigue effects. I further argue that these costs result in older adults being increasingly selective in the engagement of cognitive resources in response to these declines. This selectivity is reflected in (a) a reduction in the intrinsic motivation to engage in cognitively demanding activities, which, in part, accounts for general reductions in engagement in such activities, and (b) greater sensitivity to the self-related implications of a given task. Both processes are adaptive if viewed in terms of resource conservation, but the former may also be maladaptive to the extent that it results in older adults restricting participation in cognitively demanding activities that could ultimately benefit cognitive health. I review supportive research and make the general case for the importance of considering motivational factors in understanding aging effects on cognitive functioning.

Improving vision among older adults: behavioral training to improve sight

A major problem for the rapidly growing population of older adults (age 65 and over) is age-related declines in vision, which have been associated with increased risk of falls and vehicle crashes. Research suggests that this increased risk is associated with declines in contrast sensitivity and visual acuity. We examined whether a perceptual-learning task could be used to improve age-related declines in contrast sensitivity. Older and younger adults were trained over 7 days using a forced-choice orientation-discrimination task with stimuli that varied in contrast with multiple levels of additive noise. Older adults performed as well after training as did college-age younger adults prior to training. Improvements transferred to performance for an untrained stimulus orientation and were not associated with changes in retinal illuminance. Improvements in far acuity in younger adults and in near acuity in older adults were also found. These findings indicate that behavioral interventions can greatly improve visual performance for older adults.

Developmental regulation of ecdysone receptor (EcR) and EcR-controlled gene expression during pharate-adult development of honeybees (Apis mellifera)

Major developmental transitions in multicellular organisms are driven by steroid hormones. In insects, these, together with juvenile hormone (JH), control development, metamorphosis, reproduction and aging, and are also suggested to play an important role in caste differentiation of social insects. Here, we aimed to determine how EcR transcription and ecdysteroid titers are related during honeybee postembryonic development and what may actually be the role of EcR in caste development of this social insect. In addition, we expected that knocking-down EcR gene expression would give us information on the participation of the respective protein in regulating downstream targets of EcR. We found that in Apis mellifera females, EcR-A is the predominantly expressed variant in postembryonic development, while EcR-B transcript levels are higher in embryos, indicating an early developmental switch in EcR function. During larval and pupal stages, EcR-B expression levels are very low, while EcR-A transcripts are more variable and abundant in workers compared to queens. Strikingly, these transcript levels are opposite to the ecdysteroid titer profile. 20-hydroxyecdysone (20E) application experiments revealed that low 20E levels induce EcR expression during development, whereas high ecdysteroid titers seem to be repressive. By means of RNAi-mediated knockdown (KD) of both EcR transcript variants we detected the differential expression of 234 poly-A⁺ transcripts encoding genes such as CYPs, MRJPs and certain hormone response genes (Kr-h1 and ftz-f1). EcR-KD also promoted the differential expression of 70 miRNAs, including highly conserved ones (e.g., miR-133 and miR-375), as well honeybee-specific ones (e.g., miR-3745 and miR-3761). Our results put in evidence a broad spectrum of EcR-controlled gene expression during postembryonic development of honeybees, revealing new facets of EcR biology in this social insect.

Purpose in life as a predictor of mortality across adulthood

Having a purpose in life has been cited consistently as an indicator of healthy aging for several reasons, including its potential for reducing mortality risk. In the current study, we sought to extend previous findings by examining whether purpose in life promotes longevity across the adult years, using data from the longitudinal Midlife in the United States (MIDUS) sample. Proportional-hazards models demonstrated that purposeful individuals lived longer than their counterparts did during the 14 years after the baseline assessment, even when controlling for other markers of psychological and affective well-being. Moreover, these longevity benefits did not appear to be conditional on the participants' age, how long they lived during the follow-up period, or whether they had retired from the workforce. In other words, having a purpose in life appears to widely buffer against mortality risk across the adult years.

A sociogenomic perspective on neuroscience in organizational behavior

We critically examine the current biological models of individual organizational behavior, with particular emphasis on the roles of genetics and the brain. We demonstrate how approaches to biology in the organizational sciences assume that biological systems are simultaneously causal and essentially static; that genotypes exert constant effects. In contrast, we present a sociogenomic approach to organizational research, which could provide a meta-theoretical framework for understanding organizational behavior. Sociogenomics is an interactionist approach that derives power from its ability to explain how genes and environment operate. The key insight is that both genes and the environment operate by modifying gene expression. This leads to a conception of genetic and environmental effects that is fundamentally dynamic, rather than the static view of classical biometric approaches. We review biometric research within organizational behavior, and contrast these interpretations with a sociogenomic view. We provide a review of gene expression mechanisms that help explain the dynamism observed in individual organizational behavior, particularly factors associated with gene expression in the brain. Finally, we discuss the ethics of genomic and neuroscientific findings for practicing managers and discuss whether it is possible to practically apply these findings in management.

The road not taken: life experiences in monozygotic twin pairs discordant for major depression

In an effort to understand how environmental experiences contribute to risk for major depression (MD), we conducted joint autobiographical interviews with 14 pairs of monozygotic twins (mean age 51.2) rigorously discordant for a lifetime history of MD. Twelve of the pairs could be sorted into four broad categories. In two pairs, discordance was associated with a single traumatic event occurring to the affected twin. In seven pairs, the well twin had one stable, long-term, successful romantic relationship, whereas the affected co-twin had romantic reversals one or more of which precipitated depressive episodes. These pairs varied in the degree to which the romantic problems seemed to arise from bad luck or poor choices. In one pair, occupational difficulties were strongly related to discordance in experiences with MD. In two pairs, several mechanisms seemed to be at work. Discordance in the quality of intimate love relationships was the most common etiological factor revealed by interview in these discordant pairs, with single dramatic events and occupational problems being considerably rarer. Even in this best of natural experiments, the causal interrelationship between personality, environment and depressive episodes was not always clear. Many pairs illustrated the protective effects of planfulness and the malignant effect of cumulative continuity where early difficulties in relationships shaped the subsequent life course. These results speak both to the importance of environmental influences on human well-being and psychopathology, and the complexity of the causal paths underlying their effects.

Impact of bullying in childhood on adult health, wealth, crime, and social outcomes

Bullying is a serious problem for schools, parents, and public-policymakers alike. Bullying creates risks of health and social problems in childhood, but it is unclear if such risks extend into adulthood. A large cohort of children was assessed for bullying involvement in childhood and then followed up in young adulthood in an assessment of health, risky or illegal behavior, wealth, and social relationships. Victims of childhood bullying, including those that bullied others (bully-victims), were at increased risk of poor health, wealth, and social-relationship outcomes in adulthood even after we controlled for family hardship and childhood psychiatric disorders. In contrast, pure bullies were not at increased risk of poor outcomes in adulthood once other family and childhood risk factors were taken into account. Being bullied is not a harmless rite of passage but throws a long shadow over affected people's lives. Interventions in childhood are likely to reduce long-term health and social costs.

Keeping it steady: older adults perform more consistently on cognitive tasks than younger adults

People often attribute poor performance to having bad days. Given that cognitive aging leads to lower average levels of performance and more moment-to-moment variability, one might expect that older adults should show greater day-to-day variability and be more likely to experience bad days than younger adults. However, both researchers and ordinary people typically sample only one performance per day for a given activity. Hence, the empirical basis for concluding that cognitive performance does substantially vary from day to day is inadequate. On the basis of data from 101 younger and 103 older adults who completed nine cognitive tasks in 100 daily sessions, we show that the contributions of systematic day-to-day variability to overall observed variability are reliable but small. Thus, the impression of good versus bad days is largely due to performance fluctuations at faster timescales. Despite having lower average levels of performance, older adults showed more consistent levels of performance across days.

The wear and tear of daily stressors on mental health

Researchers assert that affective responses to seemingly minor daily events have long-term implications for mental health, yet this phenomenon has rarely been investigated. In the current study, we examined how levels of daily negative affect and affective reactivity in response to daily stressors predicted general affective distress and self-reported anxiety and depressive disorders 10 years after they were first assessed. Across eight consecutive evenings, participants (N = 711; age = 25 to 74 years) reported their daily stressors and their daily negative affect. Increased levels of negative affect on nonstressor days were related to general affective distress and symptoms of an affective disorder 10 years later. Heightened affective reactivity to daily stressors predicted greater general affective distress and an increased likelihood of reporting an affective disorder. These findings suggest that the average levels of negative affect that people experience and how they respond to seemingly minor events in their daily lives have long-term implications for their mental health.

The role of age and social motivation in developmental transitions in young and old adulthood

Two diary studies investigated the role of social approach and avoidance motivation in important developmental transitions in young and old adulthood. Study 1 comprised a sample of young adults (N = 93, M = 21.5 years) who moved out of their parental homes. The sample of Study 2 consisted of older adults (N = 69, M = 76.95 years) who moved into senior housing. In both studies, participants reported their habitual social approach and avoidance motives as well as their daily social experience and subjective well-being over the course of 2 weeks. In line with the literature, social approach motives and age were related to higher subjective well-being, whereas social avoidance motives were negatively associated with subjective well-being. Time since the transition was an important moderator of the association between social avoidance motives and negative outcomes. With increasing time from the transition, the negative effects of social avoidance motives decreased. The positive effects of social approach motives remained fairly stable over time. Importantly, age did not moderate any of the associations between social motivation and outcomes. Results are discussed in terms of transition-related instability and age-related stability.

Extent With Modification: Leg Patterning in the Beetle Tribolium castaneum and the Evolution of Serial Homologs

Serial homologs are similar structures that develop at different positions within a body plan. These structures share some, but not all, aspects of developmental patterning, and their evolution is thought to be constrained by shared, pleiotropic gene functions. Here we describe the functions of 17 developmental genes during metamorphic development of the legs in the red flour beetle, Tribolium castaneum. This study provides informative comparisons between appendage development in Drosophila melanogaster and T. castaneum, between embryonic and adult development in T. castaneum, and between the development of serially homologous appendages. The leg gap genes Distal-less and dachshund are conserved in function. Notch signaling, the zinc-finger transcription factors related to odd-skipped, and bric-à-brac have conserved functions in promoting joint development. homothorax knockdown alters the identity of proximal leg segments but does not reduce growth. Lim1 is required for intermediate leg development but not distal tarsus and pretarsus development as in D. melanogaster. Development of the tarsus requires decapentaplegic, rotund, spineless, abrupt, and bric-à-brac and the EGF ligand encoded by Keren. Metathoracic legs of T. castaneum have four tarsomeres, whereas other legs have five. Patterns of gene activity in the tarsus suggest that patterning in the middle of the tarsal region, not the proximal- or distal-most areas, is responsible for this difference in segment number. Through comparisons with other recent studies of T. castaneum appendage development, we test hypotheses for the modularity or interdependence of development during evolution of serial homologs.

Spatial bias and right hemisphere function: sex-specific changes with aging

Patterns of cerebral asymmetry related to visuospatial functions may change with age. The typical leftward bias on a line bisection task may reflect cerebral asymmetry. With age, such leftward bias decreases. This study demonstrated that the age-related decrease of leftward bias may actually be sex-specific. In addition, previous research suggests that young adults' deviation in line bisection may reflect asymmetric hemispheric activation of perceptual-attentional "where" spatial systems, rather than motor-intentional "aiming" spatial systems; thus, we specifically fractionated "where" and "aiming" bias of men and women ranging in age from 22 to 93 years old. We observed that older men produced greater rightward line bisection errors, of primarily "where" spatial character. However, women's errors remained leftward biased, and did not significantly change with age. "Where" spatial systems may be linked to cortico-cortical processing networks involving the posterior part of the dorsal visuospatial processing stream. Thus, the current results are consistent with the conclusion that reduced right dorsal spatial activity in aging may occur in the male, but not female, adult spatial system development.

Change You Can Believe In: Changes in Goal Setting During Emerging and Young Adulthood Predict Later Adult Well-Being

A widely held assumption is that changes in one's goals and motives for life during emerging and young adulthood have lasting influences on well-being into adulthood. However, this claim has yet to receive rigorous empirical testing. The current study examined the effects of prosocial and occupational goal change during college on adult well-being in a 17-year study of goal setting (N = 416). Using a latent growth model across three time points, both level and growth in goal setting predicted later well-being. Moreover, goal changes both during college and in young adulthood uniquely predicted adult well-being, controlling for goal levels entering college. These findings suggest that what matters for attaining adult well-being is both how you enter adulthood and how you change in response to it.

Adult hippocampal neurogenesis of mammals: evolution and life history

Substantial production of new neurons in the adult mammalian brain is restricted to the olfactory system and the hippocampal formation. Its physiological and behavioural role is still debated. By comparing adult hippocampal neurogenesis (AHN) across many mammalian species, one might recognize a common function. AHN is most prominent in rodents, but shows considerable variability across species, being lowest or missing in primates and bats. The latter finding argues against a critical role of AHN in spatial learning and memory. The common functional denominator across all species investigated thus far is a strong decline of AHN from infancy to midlife. As predicted by Altman and colleagues in 1973, this implies a role in transforming juvenile unpredictable to predictable behaviour, typically characterizing mammalian behaviour once reproductive competence has been attained. However, as only a fraction of mammalian species has been investigated, further comparative studies are necessary in order to recognize whether AHN has a common unique function, or whether it mediates species-specific hippocampal functions.

Siblings of adults with mild intellectual deficits or mental illness: differential life course outcomes

The present study contrasted the later life sibling relationships, patterns of family formation, and psychological distress and well-being of siblings of adults with disabilities to a nondisabled normative group. The authors identified 268 siblings of adults with mild intellectual deficits (ID) and 83 siblings of adults with mental illness (MI) from the Wisconsin Longitudinal Study (R. M. Hauser & W. H. Sewell, 1985; R. M. Hauser, J. Sheridan, & J. R. Warren, 1998), a prospective longitudinal study that followed participants from age 18 years to age 64 years. Compared with the norm (n = 791), siblings of adults with mild ID had more contact with family members and were more likely to live in the same state as the sibling with the disability but reported less affective closeness. Siblings of adults with MI reported more psychological distress, less psychological well-being, and less adaptive personality characteristics compared with the norm, particularly for siblings of men with MI. There were no differences between groups in the patterns of marriage and childbearing.

Saving the best for last: how adults treat social partners of different ages

Older adults report more positive feelings and fewer problems in their relationships than do younger adults. These positive experiences may partially reflect how people treat older adults. Social partners may treat older adults more kindly due to their sense that time remaining to interact with these older adults is limited. Younger (n = 87, age 22 to 35) and older (n = 89, age 65 to 77) participants indicated how positively they would behave (i.e., express affection, proffer respect, send sentimental cards) and what types of conflict strategies they would use in response to hypothetical negative interactions with two close social partners, a younger adult and an older adult. Multilevel models revealed that participants were more avoidant and less confrontational when interacting with older adults than when interacting with younger adults. Time perspective of the relationship partially mediated these age differences. Younger and older participants were also more likely to select sentimental cards for older partners than for younger partners. Findings build on socioemotional selectivity theory and the social input model to suggest that social partners facilitate better relationships in late life.

The Same Old Song?-Stability and Change in Relationship Schemas From Adolescence to Young Adulthood

Relationship schemas are core elements of personality that guide interpersonal functioning. The aim of this study is to examine stability and change in relationship schemas across two developmental epochs-adolescence and young adulthood-in the stories that people tell about their interactions with others. Using the Core Conflictual Relationship Theme Method, relationship themes were coded from semistructured interviews conducted in adolescence and again at age 25. The sample consisted of 40 participants in a longitudinal study of adolescent and young adult psychological development. There was considerable stability in the frequency with which particular themes were expressed in the narratives of adolescents and young adults. Significant changes from adolescence to young adulthood included a decrease in the perception of others as rejecting and of the self as opposing others. Young adults saw themselves and others more positively, and used a broader repertoire of themes in their relationship narratives than they had as adolescents. The basic continuity and particular changes in relationship schemas found in this study are consistent with knowledge about the adolescent-to-young-adult transition derived from other empirical and clinical findings. Relationship schemas may be rich units of study for learning about the development of interpersonal functioning.
