Social desirability bias is related to children's energy intake in a laboratory test meal paradigm. Appetite 2024; 195:107235. [PMID: 38296111 PMCID: PMC10922645 DOI: 10.1016/j.appet.2024.107235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 01/11/2024] [Accepted: 01/23/2024] [Indexed: 02/04/2024]
Abstract
Dietary intake is notoriously difficult to measure in children. Laboratory test meals address some of the methodological concerns of self-report methods, but may also be susceptible to social desirability bias, referring to the tendency for individuals to adjust their behaviors in order to be perceived more positively. The aim of the current study was to evaluate whether social desirability bias was associated with children's energy intake during a laboratory test meal, and whether this association varied by food type (total caloric intake, snack food intake, fruit/vegetable intake) and sex. A total of 82 children (M age = 9.45 ± 0.85; 50 % girls; 84.1 % rural; 85.4 % White) completed several surveys, including the Children's Social Desirability Scale and had their body composition measured. At lunchtime, they were granted access to a multi-array test meal (>5000 kcal). After adjusting for lean mass, fat mass, depressive symptoms, and parental food restriction, children who reported higher social desirability bias consumed fewer calories from snack foods (B = -11.58, p = .009, semi-partial correlation = -0.28). Boys with higher social desirability bias consumed less calories from fruits and vegetables (B = -6.47, p = .010, semi-partial correlation = -0.411); this association was not significant in girls. The desire to be perceived in a positive manner may influence children's eating behaviors in experimental paradigms. Replication studies with larger, more diverse pediatric samples are needed, as are strategies to reduce the effects of social desirability bias on test meal intake in order to enhance the validity of this dietary assessment approach.

Abstract
Exposure to adversity (e.g., poverty, bereavement) is a robust predictor of disruptions in psychological functioning. However, people vary greatly in their responses to adversity; some experience severe long-term disruptions, others experience minimal disruptions or even improvements. We refer to the latter outcomes-faring better than expected given adversity-as psychological resilience. Understanding what processes explain resilience has critical theoretical and practical implications. Yet, psychology's understanding of resilience is incomplete, for two reasons: (a) We lack conceptual clarity, and (b) two major approaches to resilience-the stress and coping approach and the emotion and emotion-regulation approach-have limitations and are relatively isolated from one another. To address these two obstacles,we first discuss conceptual questions about resilience. Next, we offer an integrative affect-regulation framework that capitalizes on complementary strengths of both approaches. This framework advances our understanding of resilience by integrating existing findings, highlighting gaps in knowledge, and guiding future research.

Associations Among Food Delay of Gratification, Cognitive Measures, and Environment in a Community Preschool Sample. Front Nutr 2022; 9:788583. [PMID: 35479757 PMCID: PMC9036103 DOI: 10.3389/fnut.2022.788583] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2021] [Accepted: 03/15/2022] [Indexed: 11/13/2022] Open
Abstract
Much of the work on the development of appetite self-regulation in early childhood employs tasks assessing Delay of Gratification (DoG). While this skill is thought to rely on "cool" cognitive processes like effortful control, executive functioning, and self-regulation, demonstration of how laboratory measures of food DoG relate to common assessments of those cognitive processes in community samples of children is needed. This study presents secondary data investigating the associations between two laboratory tasks of food DoG, the Snack Delay and Tongue Tasks, and an array of laboratory and parent-report cognitive measures in a sample of 88 children ages 3-6 (M age = 4.05, SD = 0.76), as well as how four measures of the child's environment were associated with food DoG. Results indicated that both measures of food DoG were positively correlated with performance on the cognitive tasks, with stronger associations observed for the Tongue Task. Family income was positively associated with food DoG as measured by the Tongue Task, and child negative life events in the past year were negatively correlated with food DoG as measured by the Snack Delay Task. These findings present the pattern of associations between cognitive tasks and food DoG, the development of which may be meaningfully affected by specific aspects of family environment.

Abstract
Parental distress is associated with less healthful child feeding practices. In this preliminary study, we examined how changes in distress from before to during the COVID-19 pandemic were associated with similar changes in feeding practices in a sample of mothers of preschool-aged children. In addition, we examined how pre-pandemic laboratory measures of maternal self-regulation moderated this association. A total of 36 mothers from an ongoing study on parent and child self-regulation completed surveys assessing parental distress (i.e., maternal depression, parenting stress) and child feeding practices during pandemic-related stay-at-home orders in May-June 2020. These mothers had completed the same measures approximately 2 years earlier, along with laboratory assessments of inhibitory and attentional control. Pre-pandemic laboratory measures of attentional control significantly moderated the association between increased maternal depression and use of controlling feeding practices, such that mothers with better attentional, but not inhibitory, control scores did not show an effect of increased depression on feeding practices. These results provide preliminary evidence that acute increases in parental distress associated with "stay-at-home" orders affect feeding practices, specifically for mothers with lower levels of attentional control abilities.

Parent Gender Affects the Influence of Parent Emotional Eating and Feeding Practices on Child Emotional Eating. Front Psychol 2021; 12:654237.

Abstract
Extant research supports a direct association between parent's own emotional eating and their child's emotional eating, and demonstrates correlations among parent emotional eating, feeding practices, and child emotional eating. However, the majority of this work focuses on the separate influences of these factors. The current study aims to add to the literature by simultaneously examining the indirect effects of three major parental feeding practices (i.e., emotion regulation, instrumental, and restrictive feeding) in the association between parent emotional eating and child emotional eating, and exploring how these indirect effects vary based on parent gender. Parents (86 fathers, 324 mothers) of an elementary school-age child (M = 8.35, SD = 2.29, range = 5-13) completed an online survey through Qualtrics Panels. Results suggested that restrictive feeding partially accounted for the association between parent and child emotional eating in the combined sample of mothers and fathers. Exploratory analyses revealed that the indirect effects of parental feeding practices in the association between parent emotional eating and child emotional eating varied based on parent gender. Among mothers, restrictive feeding was the only feeding practice that partially accounted for the association between maternal and child emotional eating, whereas all three feeding practices fully accounted for the association between father and child emotional eating. As the bulk of the literature on parent emotional eating and feeding has solely focused on mothers, these findings offer insight into how feeding practices may differentially function in the relation between parent emotional eating and child emotional eating for mothers versus fathers.

Abstract
Parents and other primary caregivers affect the development of children's self-regulation in myriad ways, including via the parent's own self-regulation abilities. Ample evidence supports the association between mother and child self-regulation, yet this has never been experimentally assessed with regard to appetite self-regulation, the self-regulation of food intake. This study sought to explicitly test the associations between mother and child self-regulation across 3 domains: (1) appetite, (2) attentional control, and (3) inhibitory control. A community sample of 88 mother-preschooler dyads (ages 3-5) participated in this cross-sectional, experimental study. Results demonstrated that maternal self-regulation was significantly positively associated with child self-regulation in the appetite domain, b = 0.52, t(63.54) = 2.39, p = .020, but not for attentional or inhibitory control. These results add to the literature on parental influences on self-regulation development in early childhood and suggest that patterns of mother-child associations may vary across domains of self-regulation.

Delay of Gratification Predicts Eating in the Absence of Hunger in Preschool-Aged Children. Front Psychol 2021; 12:650046.

Abstract
Poor ability to regulate one's own food intake based on hunger cues may encourage children to eat beyond satiety, leading to increased risk of diet-related diseases. Self-regulation has multiple forms, yet no one has directly measured the degree to which different domains of self-regulation predict overeating in young children. The present study investigated how three domains of self-regulation (i.e., appetitive self-regulation, inhibitory control, and attentional control) predicted eating in the absence of hunger (EAH) in a community sample of 47 preschool-aged children (M age = 4.93, SD = 0.86). Appetitive self-regulation, as measured using a delay of gratification task, was significantly and negatively associated with EAH 1 year later (p < 0.5). Measures of inhibitory and attentional control did not significantly predict EAH. These results suggest that food-related self-regulation may be a better predictor of overeating behaviors than general measures of self-regulation.

Perceived Neighborhood Crime Safety Moderates the Association Between Racial Discrimination Stress and Chronic Health Conditions Among Hispanic/Latino Adults. Front Public Health 2021; 9:585157.

Abstract
Background: Little is known about the link between perceived neighborhood walkability and prevalence of chronic disease. Even less is known regarding this association among Hispanic/Latino adults, despite exhibiting high rates of chronic diseases. Stress due to racial discrimination is a harmful social determinant of health in Hispanics/Latinos. Having both low perceived neighborhood walkability and high racial discrimination stress may exacerbate the chronic disease status of Hispanics/Latinos. Among a U.S. national sample of Hispanic/Latino adults, this cross-sectional study aims to examine (1) the associations among overall perceived neighborhood walkability, racial discrimination stress, and having a chronic health condition; and (2) whether overall perceived neighborhood walkability moderates the hypothesized association between racial discrimination stress and having a chronic health condition. Methods: In January 2018, 798 Hispanic/Latino adults (M age = 39.7 years, SD = 15.1; 58.6% female; 70.0% U.S. born; 52.0% Mexican/Mexican American) responded to a survey via Qualtrics Panels. Surveys included the Neighborhood Environment Walkability Scale-Abbreviated, Hispanic Stress Inventory-2, and self-reported presence/absence of chronic health conditions (e.g., hypertension, heart disease). A logistic regression was conducted testing for the moderation of the main effect of racial discrimination stress on the presence of a chronic health condition by overall perceived neighborhood walkability. Results: After controlling for age, body mass index, and income, racial discrimination stress was inversely associated with overall perceived neighborhood walkability (b = -0.18, p < 0.001) and positively associated with having a chronic health condition (OR = 1.02; 95% CI [1.00, 1.03]). While overall perceived neighborhood walkability was not associated with having a chronic health condition, perceived crime safety was inversely associated with having a chronic health condition (OR = 0.94; 95% CI [0.89, 0.99]). Perceived crime safety moderated the positive association between discrimination stress and having a chronic health condition, such that the association was only significant among those who perceived their neighborhood to be less safe (β = -0.004, 95% CI [-0.01, -0.00]). Conclusions: Overall perceived neighborhood walkability was inversely associated with racial discrimination stress, but not associated with having a chronic health condition. Perceived neighborhood crime safety, but not infrastructure or aesthetics, matters when it comes to the link between racial discrimination stress and having a chronic health condition among Hispanics/Latinos.

Neural Substrates of Food Valuation and Its Relationship With BMI and Healthy Eating in Higher BMI Individuals. Front Behav Neurosci 2020; 14:578676.

Abstract
Considerable evidence points to a link between body mass index (BMI), eating behavior, and the brain's reward system. However, much of this research focuses on food cue reactivity without examining the subjective valuation process as a potential mechanism driving individual differences in BMI and eating behavior. The current pre-registered study (https://osf.io/n4c95/) examined the relationship between BMI, healthy eating, and subjective valuation of healthy and unhealthy foods in a community sample of individuals with higher BMI who intended to eat more healthily. Particularly, we examined: (1) alterations in neurocognitive measures of subjective valuation related to BMI and healthy eating; (2) differences in the neurocognitive valuation for healthy and unhealthy foods and their relation to BMI and healthy eating; (3) and whether we could conceptually replicate prior findings demonstrating differences in neural reactivity to palatable vs. plain foods. To this end, we scanned 105 participants with BMIs ranging from 23 to 42 using fMRI during a willingness-to-pay task that quantifies trial-by-trial valuation of 30 healthy and 30 unhealthy food items. We measured out of lab eating behavior via the Automated Self-Administered 24 H Dietary Assessment Tool, which allowed us to calculate a Healthy Eating Index (HEI). We found that our sample exhibited robust, positive linear relationships between self-reported value and neural responses in regions previously implicated in studies of subjective value, suggesting an intact valuation system. However, we found no relationship between valuation and BMI nor HEI, with Bayes Factor indicating moderate evidence for a null relationship. Separating the food types revealed that healthy eating, as measured by the HEI, was inversely related to subjective valuation of unhealthy foods. Imaging data further revealed a stronger linkage between valuation of healthy (compared to unhealthy) foods and corresponding response in the ventromedial prefrontal cortex (vmPFC), and that the interaction between healthy and unhealthy food valuation in this region is related to HEI. Finally, our results did not replicate reactivity differences demonstrated in prior work, likely due to differences in the mapping between food healthiness and palatability. Together, our findings point to disruptions in the valuation of unhealthy foods in the vmPFC as a potential mechanism influencing healthy eating.

Brain Activity Associated With Regulating Food Cravings Predicts Changes in Self-Reported Food Craving and Consumption Over Time. Front Hum Neurosci 2020; 14:577669.

Abstract
Neural patterns associated with viewing energy-dense foods can predict changes in eating-related outcomes. However, most research on this topic is limited to one follow-up time point, and single outcome measures. The present study seeks to add to that literature by employing a more refined assessment of food craving and consumption outcomes along with a more detailed neurobiological model of behavior change over several time points. Here, a community sample of 88 individuals (age: M = 39.17, SD = 3.47; baseline BMI: M = 31.5, SD = 3.9, range 24–42) with higher body mass index (BMI) performed a food craving reactivity and regulation task while undergoing functional magnetic resonance imaging. At that time—and 1, 3, and 6 months later—participants reported craving for and consumption of healthy and unhealthy foods via the Food Craving Inventory (FCI) and ASA24 (N at 6 months = 52–55 depending on the measure). A priori hypotheses that brain activity associated with both viewing and regulating personally desired unhealthy, energy-dense foods would be associated with self-reported craving for and consumption of unhealthy foods at baseline were not supported by the data. Instead, regression models controlling for age, sex, and BMI demonstrated that brain activity across several regions measured while individuals were regulating their desires for unhealthy food was associated with the self-reported craving for and consumption of healthy food. The hypothesis that vmPFC activity would predict patterns of healthier eating was also not supported. Instead, linear mixed models controlling for baseline age and sex, as well as changes in BMI, revealed that more regulation-related activity in the dlPFC, dACC, IFG, and vmPFC at baseline predicted decreases in the craving for and consumption of healthy foods over the course of 6 months.

Abstract
OBJECTIVE To describe Oregon parents' perceptions of their children's school regarding health behaviors; examine how perceptions vary by parent, child, and community characteristics; and identify recommendations for improving school environments. METHODS Oregon parents with an elementary school-aged child completed an electronic survey. RESULTS Over 90% of parents (n = 814) described their child's school as supportive of healthy eating and physical activity. Parents who ate ≥5 fruits/vegetables per day more often perceived their children's school as unsupportive of healthy eating (P < 0.001) and physical activity (P < 0.05) relative to others. Parents of children eligible for free/reduced-price lunch more often perceived the school as unsupportive of physical activity (P < 0.05) relative to others. Parental recommendations included improving school meals and providing short physical activity breaks. CONCLUSIONS AND IMPLICATIONS Parents' suggested school improvements can inform school wellness committees' and administrators' quality-improvement efforts and, in turn, better support children's healthy behaviors.

Abstract
In this article, we conduct a selective review of the literature on emotion regulation in early childhood (e.g., preschool, generally defined as ages 3-5) in regard to school readiness. Emotion regulation (ER), the process of modulating emotional arousal and expression, plays a key role in a child's ability to adapt to novel demands of school environments. This, in turn, has significant implications for both the socioemotional and academic components of a child's readiness to enter kindergarten. We begin our article with a brief review of the ER construct at this developmental stage, then review research on the impact of ER on both components of school readiness during the preschool and early elementary school years. We then discuss strategies for teachers and parents to promote ER strategy use in young children, and end with challenges regarding operationalization at this age and directions for future research.

Abstract
Although interventions that promote child-supportive parenting for children have been shown to positively impact caregiving behaviors as well as child behavioral and neurobiological functioning, less is known about which aspects of maternal brain functioning are affected by such interventions. In the present study, we conducted a preliminary evaluation of the impact of the Filming Interactions to Nurture Development (FIND) video coaching program on mothers with at least one child age four or younger. We employed a waitlist control design with pre-post data. Compared to mothers in the control condition (n = 16), mothers who received FIND (n = 16) showed changes in neural measures of inhibitory control and behavioral measures of parenting self-evaluation during a series of functional neuroimaging tasks. Specifically, we found a group by time interaction in clusters in the left inferior frontal gyrus (IFG) and insula for the Correct Stop > Correct Go contrast of the stop signal task (SST), where FIND increased brain activity associated with inhibitory control compared to mothers in the control condition; and FIND increased mothers’ endorsement of child-supportive parenting traits in the parenting self-evaluation task (PSET). Exploratory moderators, study limitations, and the implications of these findings for strength-based parenting programs are discussed.

Abstract
Recently, there has been an increase in the number of human neuroimaging studies seeking to predict behavior above and beyond traditional measurements such as self-report. This trend has been particularly notable in the area of food consumption, as the percentage of people categorized as overweight or obese continues to rise. In this review, we argue that there is considerable utility in this form of health neuroscience, modeling the neural bases of eating behavior and dietary change in healthy community populations. Further, we propose a model and accompanying evidence indicating that several basic processes underlying eating behavior, particularly reactivity, regulation, and valuation, can be predictive of behavior change. We also discuss future directions for this work.

Abstract
In this study, we utilized a novel fMRI paradigm to examine the behavioral and neural correlates of parenting self-evaluation in a sample of mothers with at least one child under the age of 4 (N = 37). Prior self-report, behavioral and observational research document the implications of parenting self-evaluations for parent well-being and caregiving behavior; however, relatively little is known about the neural circuitry underlying these self-referential processes and to what extent they are influenced by caregiving experience. Although neuroimaging paradigms indexing other aspects of parental function exist, this is the first to use functional neuroimaging to study parenting self-evaluation in a controlled laboratory setting. We found parenting self-evaluations elicited significantly greater activity across most cortical midline structures, including the medial prefrontal cortex compared to control evaluations; these findings converge with previous work on the neural underpinning of general trait self-evaluation. Notable differences by parity were observed in exploratory analyses: specifically, primiparous mothers endorsed a higher number of developmentally supportive traits, exhibited faster reaction times, and showed a greater difference in mPFC activity when making self-evaluations of developmentally supportive traits than of developmentally unsupportive traits, compared to multiparous mothers. Implications of these findings and study limitations are discussed.

Perceptions of general and postpresidential election discrimination are associated with loss of control eating among racially/ethnically diverse young men. Int J Eat Disord 2018; 51:28-38.

Abstract
OBJECTIVE The purpose of this study was to examine the association between young men's perceived experiences with discrimination, both general and following the 2016 presidential election, and their loss of control (LOC) eating. The degree to which men identified with their ethnic identity was evaluated as a moderator. METHOD The sample included 798 men (18-30 years; M = 24.0 ± 3.6) who identified as African American (n = 261), Asian/Asian American (n = 266), or Hispanic/Latino (n = 271). Participants completed an online survey of items assessing demographic characteristics; perceived discrimination; perceptions of race-related discrimination following the 2016 U.S. presidential election; ethnic identity; and LOC eating. RESULTS After adjusting for income, education, generational status and body mass index, perceived discrimination was positively associated with LOC eating frequency in African American and Hispanic/Latino men (ps < .01). Ethnic identity was inversely associated with LOC eating frequency in Hispanic/Latino men (p < .001). In Asian/Asian American men, perceived discrimination was only associated with more LOC eating among those with a low ethnic identity (p < .001). Higher levels of perceived discrimination following the presidential election were uniquely associated with more frequent LOC eating (p < .01) only among Asian/Asian American men who were not born in the United States or whose parents were not born in the United States. DISCUSSION LOC eating may partially explain known associations between discrimination and heightened risk for obesity and chronic diseases among African American and Hispanic/Latino men. Asian/Asian American men's LOC eating may be linked to postpresidential election and general experiences with racial discrimination, particularly if they report a low sense of belonging to their ethnic group.

Abstract
The stimulus sets presently used to study emotion processing are primarily static pictures of individuals (primarily adults) making emotional facial expressions. However, the dynamic, stereotyped movements associated with emotional expressions contain rich information missing from static pictures, such as the difference between happiness and pride. We created a set of 1.1 s dynamic emotional facial stimuli representing boys and girls aged 8-18. A separate group of 36 individuals (mean [M] age = 19.5 years, standard deviation [SD] = 1.95, 13 male) chose the most appropriate emotion label for each video from a superset of 250 videos. Validity and reliability statistics were performed across all stimuli, which were then used to determine which stimuli should be included in the final stimulus set. We set a criterion for inclusion of 70% agreement with the modal response made for each video. The final stimulus set contains 142 videos of 36 actors (M age = 13.24 years, SD = 2.09, 14 male) making negative (disgust, embarrassment, fear, sadness), positive (happiness, pride), and neutral facial expressions. The percent correct among the final stimuli was high (median = 88.89%; M = 88.38%, SD = 7.74%), as was reliability (κ = 0.753).

Neurodevelopmental changes across adolescence in viewing and labeling dynamic peer emotions. Dev Cogn Neurosci 2017; 25:113-127. [PMID: 28262423 PMCID: PMC5764159 DOI: 10.1016/j.dcn.2017.02.003] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2016] [Revised: 12/31/2016] [Accepted: 02/04/2017] [Indexed: 11/30/2022] Open
Abstract
Dynamic peer facial stimuli recruit key regions involved in emotion processing. LPFC shows a nonlinear age trend across adolescence to labeling dynamic peer faces. MOFC/vMPFC shows a linear decrease with age to viewing dynamic peer faces. No significant age trends were observed in amygdala during viewing or labeling dynamic peer faces.
Adolescence is a sensitive period of social-affective development, characterized by biological, neurological, and social changes. The field currently conceptualizes these changes in terms of an imbalance between systems supporting reactivity and regulation, specifically nonlinear changes in reactivity networks and linear changes in regulatory networks. Previous research suggests that the labeling or reappraisal of emotion increases activity in lateral prefrontal cortex (LPFC), and decreases activity in amygdala relative to passive viewing of affective stimuli. However, past work in this area has relied heavily on paradigms using static, adult faces, as well as explicit regulation. In the current study, we assessed cross-sectional trends in neural responses to viewing and labeling dynamic peer emotional expressions in adolescent girls 10–23 years old. Our dynamic adolescent stimuli set reliably and robustly recruited key brain regions involved in emotion reactivity (medial orbital frontal cortex/ventral medial prefrontal cortex; MOFC/vMPFC, bilateral amygdala) and regulation (bilateral dorsal and ventral LPFC). However, contrary to the age-trends predicted by the dominant models in studies of risk/reward, the LPFC showed a nonlinear age trend across adolescence to labeling dynamic peer faces, whereas the MOFC/vMPFC showed a linear decrease with age to viewing dynamic peer faces. There were no significant age trends observed in the amygdala.

Age-related changes in reappraisal of appetitive cravings during adolescence. Neuroimage 2014; 108:173-81.

Abstract
The ability to regulate temptation and manage appetitive cravings is an important aspect of healthy adolescent development, but the neural systems underlying this process are understudied. In the present study, 60 healthy females evenly distributed from 10 to 23years of age used reappraisal to regulate the desire to consume personally-craved and not craved unhealthy foods. Reappraisal elicited activity in common self-regulation regions including the dorsal and ventral lateral prefrontal cortex (specifically superior and inferior frontal gyri), dorsal anterior cingulate cortex, and inferior parietal lobule. Viewing personally-craved foods (versus not craved foods) elicited activity in regions including the ventral striatum, as well as more rostral and ventral anterior cingulate cortex extending into the orbitofrontal cortex. Age positively correlated with regulation-related activity in the right inferior frontal gyrus, and negatively correlated with reactivity-related activity in the right superior and dorsolateral prefrontal cortices. Age-adjusted BMI negatively correlated with regulation-related activity in the predominantly left lateralized frontal and parietal regions. These results suggest that the age-related changes seen in the reappraisal of negative emotion may not be as pronounced in the reappraisal of food craving. Therefore, reappraisal of food craving in particular may be an effective way to teach teenagers to manage cravings for other temptations encountered in adolescence, including alcohol, drugs, and unhealthy food.

Comparison of text messaging and paper-and-pencil for ecological momentary assessment of food craving and intake. Appetite 2014; 81:131-7.

Abstract
Electronic devices such as mobile phones are quickly becoming a popular way to gather participant reports of everyday thoughts, feelings, and behaviors, including food cravings and intake. Electronic devices offer a number of advantages over alternative methods such as paper-and-pencil (PNP) assessment including automated prompts, on-the-fly data transmission, and participant familiarity with and ownership of the devices. However, only a handful of studies have systematically compared compliance between electronic and PNP methods of ecological momentary assessment (EMA), and none have examined eating specifically. Existing comparisons generally find greater compliance for electronic devices than PNP, but there is variability in the results across studies that may be accounted for by differences across research domains. Here, we compared the two EMA methods in an unexamined domain - eating - in terms of response rate and response latency, and their sensitivity to individual difference variables such as body mass index (BMI). Forty-four participants were randomly assigned to report on their food craving, food intake, and hunger four times each day for 2 weeks using either a PNP diary (N = 19) or text messaging (TXT; N = 25). Response rates were higher for TXT than PNP (96% vs. 70%) and latencies were faster (29 min vs. 79 min), and response rate and latency were less influenced by BMI in the TXT condition than in the PNP condition. These results support the feasibility of using text messaging for EMA in the eating domain, and more broadly highlight the ways that research domain-specific considerations (e.g., the importance of response latency in measuring short-lived food craving) interact with assessment modality during EMA.

Abstract
Craving of unhealthy food is a common target of self-regulation, but the neural systems underlying this process are understudied. In this study, participants used cognitive reappraisal to regulate their desire to consume idiosyncratically craved or not craved energy-dense foods, and neural activity during regulation was compared with each other and with the activity during passive viewing of energy-dense foods. Regulation of both food types elicited activation in classic top-down self-regulation regions including the dorsolateral prefrontal, inferior frontal, and dorsal anterior cingulate cortices. This main effect of regulation was qualified by an interaction, such that activation in these regions was significantly greater during reappraisal of craved (versus not craved) foods and several regions, including the dorsolateral prefrontal, inferior frontal, medial frontal, and dorsal anterior cingulate cortices, were uniquely active during regulation of personally craved foods. Body mass index significantly negatively correlated with regulation-related activation in the right dorsolateral PFC, thalamus, and bilateral dorsal ACC and with activity in nucleus accumbens during passive viewing of craved (vs. neutral, low-energy density) foods. These results suggest that several of the brain regions involved in the self-regulation of food craving are similar to other kinds of affective self-regulation and that others are sensitive to the self-relevance of the regulation target.

Emotion regulation and brain plasticity: expressive suppression use predicts anterior insula volume. Neuroimage 2011; 58:10-5.

Abstract
Expressive suppression is an emotion regulation strategy that requires interoceptive and emotional awareness. These processes both recruit the anterior insula. It is not known, however, whether increased use of expressive suppression is associated with increased anterior insula volume. In the present study, high-resolution anatomical MRI images were used to calculate insula volumes in a set of 50 healthy female subjects (mean 21.9 years) using both region of interest (ROI) and voxel-based morphometry (VBM) approaches. Participants also completed trait measures of expressive suppression usage, cognitive reappraisal usage, and negative emotional reactivity (the latter two served as control measures). As predicted, both ROI and VBM methods found that expressive suppression usage, but not negative affect and cognitive reappraisal, was positively related to anterior insula volume. These findings are consistent with the idea that trait patterns of emotion processing are related to brain structure.

Abstract
Emotion dysregulation is a key feature of mood and anxiety disorders. Many of these disorders also involve volumetric reductions in brain regions implicated in emotion regulation, including the dorsal anterior cingulate cortex (dACC). Investigating this relationship in healthy individuals may clarify the link between emotion regulation and volumetric reductions in this key brain region. High-resolution anatomical MRI images were used to calculate dACC volumes in 50 healthy female subjects. Trait measures of emotion regulation (cognitive reappraisal and expressive suppression) and negative affect were also obtained. As predicted, cognitive reappraisal was positively related to dACC volume, but not the volume of a control region, the ventral ACC. Expressive suppression, negative affect, and age were not related to dACC volume. These findings indicate that individual differences in cognitive reappraisal are related to individual differences in dACC volume in healthy participants.

The up- and down-regulation of amusement: experiential, behavioral, and autonomic consequences. ACTA ACUST UNITED AC 2009; 8:714-9.

Abstract
A growing body of research has examined the regulation of negative emotions. However, little is known about the physiological processes underlying the regulation of positive emotions, such as when amusement is enhanced during periods of stress or attenuated in the pursuit of social goals. The aim of this study was to examine the psychophysiological consequences of the cognitive up- and down-regulation of amusement. To address this goal, participants viewed brief, amusing film clips while measurements of experience, behavior, and peripheral physiology were collected. Using an event-related design, participants viewed each film under the instructions either to (a) watch, (b) use cognitive reappraisal to increase amusement, or (c) use cognitive reappraisal to decrease amusement. Findings indicated that emotion experience, emotion-expressive behavior, and autonomic physiology (including heart rate, respiration, and sympathetic nervous system activation) were enhanced and diminished in accordance with regulation instructions. This finding is a critical extension of the growing literature on the voluntary regulation of emotion, and has the potential to help us better understand how people use humor in the service of coping and social goals.

Organization of mnemonic and response operations within prefrontal cortex. Brain Res 2006; 1097:133-41.

Abstract
There is mounting evidence that prefrontal cortex (PFC) is activated during mnemonic operations such as working memory maintenance and also during response-related operations. In the current study, we examine the neural organization of mnemonic and response operations with respect to each other within PFC. Stimulus-evoked and sustained functional MRI activity was recorded during performance of a mental calculation task. The presence or absence of mnemonic and response demands was manipulated in a 2 x 2 factorial design with conditions requiring: (1) memory encoding and maintenance (M+); (2) response selection and execution (R+); (3) encoding, maintenance, and response execution (M+R+); (4) neither mnemonic nor response-related processes (M-R-). The first step of the analyses identified PFC voxels exhibiting differential activity during (M+) vs. (R+) trials. Within these voxels, we then examined activity during multiple phases of (M+R+) trials. Greater stimulus-evoked and sustained activity was observed within the anterior extent of dorsolateral prefrontal cortex (BA 46) during R+ vs. M+ trials. In contrast, greater activity was observed in the posterior extent of dorsolateral PFC during M+ vs. R+ trials. Importantly, both regions were activated during (M+R+) trials. Activity levels during all of these conditions exceeded levels observed during (M-R-) control trials. These results suggest that integrative functions of PFC that allow past information to guide future actions may emerge from communication between discrete subregions supporting mnemonic and response operations.

Method for multimodal analysis of independent source differences in schizophrenia: combining gray matter structural and auditory oddball functional data. Hum Brain Mapp 2006; 27:47-62.

Abstract
The acquisition of both structural MRI (sMRI) and functional MRI (fMRI) data for a given study is a very common practice. However, these data are typically examined in separate analyses, rather than in a combined model. We propose a novel methodology to perform independent component analysis across image modalities, specifically, gray matter images and fMRI activation images as well as a joint histogram visualization technique. Joint independent component analysis (jICA) is used to decompose a matrix with a given row consisting of an fMRI activation image resulting from auditory oddball target stimuli and an sMRI gray matter segmentation image, collected from the same individual. We analyzed data collected on a group of schizophrenia patients and healthy controls using the jICA approach. Spatially independent joint-components are estimated and resulting components were further analyzed only if they showed a significant difference between patients and controls. The main finding was that group differences in bilateral parietal and frontal as well as posterior temporal regions in gray matter were associated with bilateral temporal regions activated by the auditory oddball target stimuli. A finding of less patient gray matter and less hemodynamic activity for target detection in these bilateral anterior temporal lobe regions was consistent with previous work. An unexpected corollary to this finding was that, in the regions showing the largest group differences, gray matter concentrations were larger in patients vs. controls, suggesting that more gray matter may be related to less functional connectivity in the auditory oddball fMRI task.

Voxel-based morphometry versus region of interest: a comparison of two methods for analyzing gray matter differences in schizophrenia. Schizophr Res 2005; 74:135-47.

Abstract
Many previous studies exploring cortical gray matter (GM) differences in schizophrenia have used "region of interest" (ROI) measurements to manually delineate GM volumes. Recently, some investigators have instead employed voxel-based morphometry (VBM), an automated whole-brain magnetic resonance image measurement technique. The purpose of the current study was to compare the above methods in calculating GM distributions in schizophrenia patients relative to matched controls. Using ROIs, Buchanan et al. (Buchanan, R.W., Francis, A., Arango, C., Miller, K., Lefkowitz, D.M., McMahon, R.P., Barta, P.E. and Pearlson, G.D., 2004. Morphometric assessment of the heteromodal association cortex in schizophrenia. Am J Psychiatry. 161 (2), 322-331.) found decreased dorsolateral prefrontal GM volume and altered symmetry of inferior parietal GM in schizophrenia patients. We hypothesized that VBM analyses of the same data would complement the ROI findings. As predicted, VBM analyses replicated results of less left inferior and right superior frontal cortical GM in schizophrenia. Additionally, VBM uncovered a significantly lower concentration of GM in the middle and superior temporal gyri, sought but not detected using ROIs, but did not replicate the parietal changes. The principal explanation for these differences may be the methodological differences between voxel-averaged, landmark-based ROI analyses and the single, voxel-by-voxel whole brain VBM measurements. Although VBM is rapid and fully automated, it is not a replacement for manual ROI-based analyses. Both methods provide different types of information and should thus be used in tandem.
