Self-grounding visual, auditory and olfactory autobiographical memories

Employees' experiences of personal and collective work-identity in the context of an organizational change

In the present study we investigated employees' experiences of personal and collective work-identity in the context of an organizational change. Data consisted of semi-structured interviews with employees that will be affected by the change. We conducted a theory-driven thematic analysis based on four predetermined main themes: personal and collective emotional, and cognitive work-identity. Respondents experienced distinct and unambiguous proudness, bonding, familiarity and missing in their personal emotional work-identity, and quite distinct and unambiguous coherence, reflection, mental time travel, but ambivalent, or even lack of, correspondence in their personal cognitive work-identity. They experienced a mix of distinct and ambiguous organizational proudness, esteem and affective commitment in their collective emotional work-identity. They experienced distinct and unambiguous identification with the organization, but ambivalent assimilation and incorporation of the organization in their collective cognitive work-identity. Such a complexity in the employees' work-identity experiences also indicates complexity in their organizational change reactions.

Olfactory imagery as a retrieval method for autobiographical memories

INTRODUCTION

The retrieval of autobiographical memories is influenced by several factors, such as sensory modality and the emotional salience of memory cues. This study aimed at investigating the interaction between sensory modalities (olfaction, vision) and emotional dimensions (valence, arousal) of imagery cues, on the frequency, quality, and age distribution of the autobiographical memories (AMs) elicited.

METHOD

A total of 296 females (aged between 18 and 35 years) received one out of eight brief instructions for olfactory or visual imagery. The participants were asked to create a mental image with either high arousal/positive valence, high arousal/negative valence, low arousal/positive valence, or low arousal/negative valence (e.g., 'imagine an unpleasant and arousing odor/scene'); no specific stimulus was mentioned in the instruction.

RESULTS

The approach used elicited imagery with autobiographical content in the majority of participants (78%). In terms of frequency, odor imagery, compared to visual imagery, turned out to be more effective at retrieving either unpleasant memories associated with experiences in adulthood, or pleasant childhood memories. In terms of quality, the imagery was rated as less vivid in the olfactory compared to the visual condition (irrespective of valence and arousal of the imagery instruction). Visual imagery was associated with the experience of more diverse emotions (happiness, sadness, anxiety, anger) than odor imagery, which was related primarily with disgust and happiness.

CONCLUSION

Our findings indicate that nonspecific imagery induction is a useful approach in accessing AM.

IMPLICATION

This approach presents promising clinical applications, such as in working with autobiographical memory narratives in psychotherapy.

Remembering beloved objects from early childhood, middle childhood, and adolescence and the role of the five senses

ABSTRACTBeloved objects are cherished and valued possessions that we feel attached to. Previous research has demonstrated that the functions of beloved objects change across a lifespan. However, beloved objects may not only be appreciated because of their functions but also because of their sensory qualities. We hypothesised that the sensory experiences with beloved objects show a developmental trajectory and that the proximal senses (touch, taste, smell) become less important across childhood and adolescence, while the distant senses (vision, hearing) become more important. Moreover, we assumed that the observed changes in the sensory experiences are associated with the corresponding changes of functions across life stages. Building on the idea that those (perceptual) aspects of our environment that are particularly important to us are preferentially stored in memory, we hypothesised that this developmental trajectory would also be reflected in retrospective accounts. Hence, participants (N = 225) were asked to remember beloved objects from early childhood, middle childhood, and adolescence, to describe their functions and to answer questions regarding their sensory experiences with the objects. The mixed methods data analyses confirmed our hypotheses. Taken together, our study illustrates and underlines the importance of beloved objects for thinking, behaviour, memory, and identity.

Emotion and cognition in personal and collective work-identity formation: variable- and person-oriented analyses

The aim of this study was to investigate emotional and cognitive processes involved in the formation of personal and collective work-identity by variable- and person-oriented analyses. A digitized questionnaire was answered by 768 participants. In line with an autobiographical (personal) memory view, we showed that: (1) emotional processes positively predicted cognitive processes (variable-oriented analyses), and (2) emotional profile had an effect on cognitive processes (person-oriented analyses), with regard to personal work-identity formation. Regarding collective work-identity formation, and in line with a social-identity and self-categorization perspective, we showed that: (1) cognitive processes positively predicted emotional processes (variable-oriented analyses), and (2) cognitive profile had an effect on emotional processes (person-oriented analyses). Our results indicate that emotion and cognition play different roles in personal- and collective work-identity formation; additionally, suggesting that the theoretical views of both personal and social psychology as well as analyses at different levels should be involved in order to gain a deeper understanding of the phenomenon of people-work bonding.

Do you remember? Similarities and differences between the earliest childhood memories for the five senses

We perceive the world with our five senses. However, the role that these five senses play in early childhood memories has received relatively little attention. Against this background, participants (N = 117) were asked to write down their earliest childhood memories for the five senses and to answer additional questions regarding these memories. There was no significant difference between the five senses regarding the percentage of participants reporting a memory or between the valence and the subjective reliability of the reported memories. However, memories reported for sight were marginally longer, from a younger age, and estimated to be more important compared to memories reported for the other senses. A qualitative content analysis revealed that the vast majority of the reported memories fell into a limited number of categories. Interestingly, several categories played a role in more than one sense. Nevertheless, the reported memories also mirrored the characteristic properties that one is able to perceive with each sense. Overall, the findings support the notion that sight is the dominant sense. At the same time, they remind us that each sense provides us with unique information about ourselves and the world around us.

The Proust Machine: What a Public Science Event Tells Us About Autobiographical Memory and the Five Senses

Our senses are constantly stimulated in our daily lives but we have only a limited understanding of how they affect our cognitive processes and, especially, our autobiographical memory. Capitalizing on a public science event, we conducted the first empirical study that aimed to compare the relative influence of the five senses on the access, temporal distribution, and phenomenological characteristics of autobiographical memories in a sample of about 400 participants. We found that the access and the phenomenological features of memories varied as a function of the type of sensory cues, but not their temporal distribution. With regard to their influence on autobiographical memory, an overlap between some senses was found, with on one hand, olfaction and taste and, on the other, vision, audition, and touch. We discuss these findings in the light of theories of perception, memory, and the self, and consider methodological implications of the sensory cuing technique in memory research, as well as clinical implications for research in psychopathological and neuropsychological populations.

Sensory Cueing of Autobiographical Memories in Normal Aging and Alzheimer's Disease: A Comparison Between Visual, Auditory, and Olfactory Information

BACKGROUND

Alzheimer's disease (AD) is a chronic, neurodegenerative disease resulting in a progressive decline of autobiographical memories (AMs) which favors the development of psycho-behavioral disorders. One of the most popular psychosocial interventions in dementia care, Reminiscence Therapy, commonly uses sensory cueing to stimulate AMs retrieval. However, few empirical studies have investigated the impact of sensory stimulation on AMs retrieval in AD.

OBJECTIVE

Our goal was to determine the most relevant cue for AMs retrieval in patients with early to mild AD when comparing odors, sounds and pictures.

METHODS

Sixty AD patients, 60 healthy older adults (OA), and 60 healthy young adults (YA) participated in our study. Participants were presented with either 4 odors, 4 sounds, or 4 pictures. For each stimulus, they were asked to retrieve a personal memory, to rate it across 3 dimensions (emotionality, vividness, rarity) and then to date it.

RESULTS

Overall, results showed no clear dominance of one sensory modality over the others in evoking higher-quality AMs. However, they show that using pictures is the better way to stimulate AD patients' AM, as it helps to retrieve a higher number of memories that are also less frequently retrieved, followed by odors. By contrast, auditory cueing with environmental sounds presented no true advantage.

CONCLUSION

Our data should help dementia care professionals to increase the efficiency of Reminiscence Therapy using sensory elicitors. Other clinical implications and future directions are also discussed.

Teachers' Personal and Collective Work-Identity Predicts Exhaustion and Work Motivation: Mediating Roles of Psychological Job Demands and Resources

The aim of this study was to investigate the mediating roles of teachers' psychological job demands and resources regarding personal and collective work-identity, respectively, and exhaustion and self-determined work motivation, respectively. A total of 2,905 members of a Swedish teacher's trade union received an online questionnaire by e-mail; 768 individuals answered the questionnaire and so participated in this study. The data were obtained by self-reported measures (e.g., emotional and cognitive components of work-identity, psychological job demands and resources, exhaustion and work motivation) and analyzed by mediation regression analyses. The results showed that teachers' psychological job demands (prosocial extra-role performance) mediated relationships between cognitive personal work-identity and emotional collective work-identity, respectively, and exhaustion. Teachers' psychological job resources (educational inspiration) mediated relationships between emotional personal work-identity and cognitive collective work-identity, respectively, and self-determined work motivation. Thus, teachers might be disadvantaged by stronger personal work-related thinking and collective work-related feeling when related to exhaustion, to some extent accounted for by psychological job demands, and they might find advantage in stronger personal work-related feeling and collective work-related thinking when related to work motivation, to some extent accounted for by psychological job resources.

An in-depth review of the methods, findings, and theories associated with odor-evoked autobiographical memory

Over the past nearly 35 years, there has been sporadic interest in what has commonly come to be known as the Proust phenomenon, whereby autobiographical memories are retrieved and experienced differently when evoked by odors as compared with other types of cues, such as words, images or sounds. The purpose of this review is threefold. First, we provide a detailed analysis of the methods used to investigate Proust effects. Second, we review and analyze the various findings from the literature and determine what we feel to be the most important and stable findings. Third, we provide a series of previously postulated and new hypotheses that attempt to account for the various findings. Given the early stage of research, the current review aims to provide a measure of organization to the field, as well serve as a guide for how future investigations may address the topic. We conclude with the recommendation that research in this area shift its focus from establishing the phenomenon towards explaining its causes.

Predicting general mental health and exhaustion: the role of emotion and cognition components of personal and collective work-identity

The aim of this study was to investigate relationships between emotion and cognition components of personal and collective work-identity and self-reported general mental health and exhaustion, in Swedish teachers (N = 768). In line with our predictions, we showed that the emotion component of personal work-identity and the cognition component of collective work-identity associated positively with general mental health and negatively with exhaustion. The reverse result was found, however, for the cognition component of personal work-identity and emotion component of collective work-identity. In general, all this indicates that person-work bonding might, to some degree, account for general mental health and exhaustion in employees. In particular, the findings suggest that general mental health and exhaustion may vary symmetrically across the: (1) Type of person-work bonding (personal vs. collective work-identity); and (2) Type of psychological component (emotion vs. cognition) involved in personal- and collective work-identity.

Wellbeing in Urban Greenery: The Role of Naturalness and Place Identity

The aim was to investigate effects of urban greenery (high vs. low naturalness) on place identity and wellbeing, and the links between place identity and wellbeing. It was shown that participants (Gothenburg, Sweden, N = 1347) estimated a stronger attachment/closeness/belonging (emotional component of place-identity), and more remembrance and thinking about and mental travel (cognitive component of place-identity) in relation to high vs. low perceived naturalness. High naturalness was also reported to generate higher wellbeing in participants than low naturalness. Furthermore, place identity was shown to predict participants' wellbeing in urban greenery, accounting for 35% of variance explained by the regression. However, there was a stronger relationship between the emotional vs. the cognitive component of place identity and wellbeing. Finally, a significant role of place identity in mediating the naturalness-wellbeing relationship was shown, indicating that the naturalness-wellbeing connection can be partly accounted for by the psychological mechanisms of people-place bonding.

Motivation and Justice at Work: The Role of Emotion and Cognition Components of Personal and Collective Work Identity

The aim of this study was to investigate the role of personal and collective work identity (including emotion and cognition components), in predicting work motivation (operationalized as work self-determined motivation) and organizational justice (operationalized as organizational pay justice). Digitized questionnaires were distributed by e-mail to 2905 members, teachers, of a Swedish trade union. A total of 768 individuals answered the questionnaire and by that participated in this study. Personal- compared to collective work identity was shown to positively associate with self-determined motivation accounted for by the emotion component of personal work identity. Collective compared to personal work identity was reported to positively associate with organizational pay justice accounted for by the cognition component of collective work identity. All this suggests that both work-related motivation and organizational justice might be, to some extent, accounted for by the psychological mechanisms of work identity and that, as predicted, different types of work identity, play different significant roles in predicting motivation and justice at work. More precisely, the emotion component of work identity was more pronounced in personal work-bonding relationships, and the cognitive component, of work identity in contrast, was more pronounced in collective work-bonding relationships.

Guilt as a Motivator for Moral Judgment: An Autobiographical Memory Study

The aim was to investigate the phenomenology of self-defining moral memory and its relations to self-conscious feelings of guilt and willingness to do wrong (moral intention) in social and economic moral situations. We found that people use guilt as a moral motivator for their moral intention. The reparative function of guilt varied, however, with type of situation; that is, participants felt guiltier and were less willing to do wrong in economic compared to social moral situations. The self-defining moral memory was shown to be relatively more easy to access (accessibility), logically structured (coherence), vivid, seen from the first-person perspective (visual perspective), real (sensory detail); but was relatively less positive (valence), emotionally intense, chronologically clear (time perspective), in agreement with the present self (distancing), and shared. Finally, it was indicated that the more guilt people felt the more hidden/denied (less accessible), but more real (more sensory details), the self-defining moral memory.
