The valence and the functions of autobiographical memories: Does intensity matter?

Autobiographical memories serve psychosocial functions in daily life and the use of memories is related to their valence. In the present study, we examined whether functions are also related to the intensity of positive and negative memories. Our sample included 110 participants (57–89 years of age). Memories were prompted with 30 emotionally neutral cue words. Participants rated the emotional quality of each memory and indicated how frequently they had recalled it for self-continuity, directing behavior, social-bonding, and mood-enhancement. We used multilevel modeling to test whether individual differences in the use of memories can explain why individuals recall different numbers of positive and negative memories as well as memories high or low in intensity. Each function revealed its specific pattern regarding valence and intensity but also regarding within-person and between-person effects. Mood-enhancement showed the strongest relations, which points to the importance of considering emotion regulation as a function of autobiographical memory.     

Emotions and false memories: valence or arousal?

The effects of mood on false memories have not been studied systematically until recently. Some results seem to indicate that negative mood may reduce false recall and thus suggest an influence of emotional valence on false memory. The present research tested the effects of both valence and arousal on recall and recognition and indicates that the effect is actually due to arousal. In fact, whether participants' mood is positive, negative, or neutral, false memories are significantly more frequent under conditions of high arousal than under conditions of low arousal.     

How are depression and autobiographical memory retrieval related to culture?

This study investigated how culture influences the association between autobiographical memory retrieval and depression. Thirty clinically depressed patients and 30 controls, 15 each from Britain and Taiwan, completed the English and Chinese versions of the Autobiographical Memory Cueing Task (AMT). Overall, the depressed individuals from both cultural groups retrieved significantly fewer specific and more categoric autobiographical memories than their matched, nondepressed controls. Within the control groups, the British participants retrieved significantly more specific autobiographical memories and fewer categoric memories than their Taiwanese counterparts. These results suggest that difficulty in retrieving specific autobiographical memories typical of depression may be a cognitive bias that occurs across cultures.     

Imagination and memory: Does imagining implausible events lead to false autobiographical memories?

Previous studies have reported that imagination can induce false autobiographical memories. This finding has been used to suggest that psychotherapists who have clients imagine suspected repressed memories of childhood sexual abuse may, in fact, be inducing false memories for the imagined events. In this study, at Time 1 and then, 2 weeks later, at Time 2, 145 subjects rated each of 20 events on the Life Events Inventory as to whether each had occurred to them in childhood. One week after Time 1, the subjects were told that 2 target events were plausible and 2 were implausible. They were then asked to imagine 1 plausible and 1 implausible target event. Plausibility and imagining interacted to affect occurrence ratings; whereas imagining plausible events increased the change in occurrence ratings, imagining implausible events had no effect on occurrence ratings.     

Involuntary autobiographical memories in and outside the laboratory: How different are they from voluntary autobiographical memories?

In two studies, we compared the characteristics and retrieval times of involuntary and voluntary autobiographical memory under controlled laboratory conditions. A new laboratory task of involuntary autobiographical memories involved detecting vertical lines in a stream of stimuli with horizontal lines (an undemanding vigilance task) and recording any involuntary memories during the session. The majority of these memories were reported as being triggered by irrelevant cue phrases presented on the screen. Voluntary autobiographical memories were sampled via a standard word-cue method in Session 2. The results showed that involuntary memories were more specific and were retrieved significantly faster than voluntary memories. They were also more likely to be triggered by negative cues, whereas cue valence did not have any effect on the number of voluntary memories. Furthermore, laboratory involuntary memories did not differ from naturalistic involuntary memories recorded in a diary by the same participants (Study 2). Taken together, these results have important implications for current theories of autobiographical memory, and they open up interesting avenues for future research.     

Differences in adult and adolescent listeners’ ratings of valence and arousal in emotional prosody

ABSTRACT

Judgments of emotional stimuli’s valence and arousal can differ based on the perceiver’s age. With most of the existing literature on age-related changes in such ratings based on perceptions of visually-presented pictures or words, less is known about how youth and adults perceive and rate the affective information contained in auditory emotional stimuli. The current study examined age-related differences in adolescent (n?=?31; 45% female; aged 12–17, M?=?14.35, SD?=?1.68) and adult listeners’ (n?=?30; 53% female; aged 21–30, M?=?26.20 years, SD?=?2.98) ratings of the valence and arousal of spoken words conveying happiness, anger, and a neutral expression. We also fitted closed curves to the average ratings for each emotional expression to determine their relative position on the valence-arousal plane of an affective circumplex. Compared to adults, adolescents’ ratings of emotional prosody were generally higher in valence, but more constricted in range for both valence and arousal. This pattern of ratings is suggestive of lesser differentiation amongst emotional categories’ holistic properties, which may have implications for the successful recognition and appropriate response to vocal emotional cues in adolescents’ social environments.     

Induced forgetting and reduced confidence in our personal past? The consequences of selectively retrieving emotional autobiographical memories

People build their sense of self, in part, through their memories of their personal past. What is striking about these personal memories is that, in many instances, they are inaccurate, yet confidently held. Most researchers assume that confidence ratings are based, in large part, on the memory's mnemonic features. That is, the more vivid or detailed the memory, the higher the confidence people have in its accuracy. However, we explore a heretofore underappreciated source on which confidence ratings may be based: the accessibility of memories as a result of selective retrieval. To explore this possibility, we use Anderson, Bjork, and Bjork's retrieval-induced forgetting (RIF) paradigm with emotional (positive and negative) autobiographical memories. We found the standard RIF effect for memory recall across emotional valence. That is, selective retrieval of emotional autobiographical memories induced forgetting of related, but not retrieved emotional autobiographical memories compared to the baseline. More interestingly, we found that the confidence ratings for positive memories mirrored the RIF pattern: decreased confidence for related, unpracticed autobiographical memories relative to the baseline. For negative memories, we found the opposite pattern: increased confidence for both practiced autobiographical memories and related, unpracticed autobiographical memories. We discuss these results in terms of accessibility, the diverging mnemonic consequences of selectively retrieving positive and negative autobiographical memories and personal identity.     

Whose life is it anyway? Adoption of each other's autobiographical memories by twins

Anecdotal evidence suggests that twins may dispute ownership of autobiographical experiences. We investigated the frequency and characteristics of such disputed memories in comparison to memories with undisputed ownership. In the present study, monozygotic twins (MZ), dizygotic twins (DZ), and siblings were asked to remember disputed and non‐disputed memories. They also dated each memory and provided a rating on the following variables: level of imagery, detail, rehearsal, and importance. Results showed that disputed memories were more common among MZ twins than in DZ twins and siblings. The frequencies of undisputed memories were not different among the three groups. When compared to non‐disputed memories, disputed memories were more likely to come from events experienced during preschool years. We consider disputed memories as instances of false memories, at least partly influenced by social interactional processes, and event characteristics. Copyright © 2003 John Wiley & Sons, Ltd.     

Does exposure to ambient odors influence the emotional content of memories?

This study examined the effects of implicitly presented odors on the emotional content of memory narratives. Participants were exposed to low levels of perfumes or no odors while they reconstructed a memory from childhood and a recurrent dream. Narratives were analyzed for emotional content using the Linguistic and Inquiry Word Count program. Exposure to perfumes increased the percentage of positive emotion words used by participants in recalling both dreams and childhood memories. In addition, exposure to odors decreased the percentage of negative emotion words that men used in their narratives, whereas the opposite effect was found for women. Discussion focuses on gender differences in written emotional expression, possible ways by which perfumes may exert their effects, and the usefulness of using ambient odors and objective content analysis when studying emotions in memories.     

Daily experiences and well-being: Do memories of events matter?

Retrospective subjective well-being (SWB) refers to self-reported satisfaction and emotional experience over the past few weeks or months. Two studies investigated the mechanisms linking daily experiences to retrospective SWB. Participants reported events each day for 21 days (Study 1) or twice a week for two months (Study 2). The emotional intensity of each event was rated: (1) when it had recently occurred (proximal intensity); and (2) at the end of the event-reporting period (distal intensity). Both sets of ratings were then aggregated across events and used to predict retrospective SWB at the end of the study. Path analyses showed that proximal intensity predicted retrospective SWB whereas distal intensity did not. The effect remained even after controlling for trait happiness and neuroticism. These results suggest that daily experiences influence retrospective SWB primarily through abstract representations of the past few weeks or months (as measured by aggregated proximal intensity ratings) rather than the explicit recollection of individual events during the same period (as measured by aggregated distal intensity ratings). Retrospective SWB, in turn, mediated the effect of daily experiences on global SWB (i.e., self-reported satisfaction and emotional experiences in general).     

Developmental changes in consistency of autobiographical memories: adolescents’ and young adults’ repeated recall of recent and distance events

Autobiographical memories contribute continuity and stability to one’s self yet they also are subject to change: they can be forgotten or be inconsistently remembered and reported. In the present research, we compared the consistency of two reports of recent and distant personal events in adolescents (12- to 14-year-olds) and young adults (18- to 23-year-olds). In line with expectations of greater mnemonic consistency among young adults relative to adolescents, adolescents reported the same events 80% of the time compared with 90% consistency among young adults; the significant difference disappeared after taking into consideration narrative characteristics of individual memories. Neither age group showed high levels of content consistency (30% vs. 36%); young adults were more consistent than adolescents even after controlling for other potential predictors of content consistency. Adolescents and young adults did not differ in consistency of estimating when their past experiences occurred. Multilevel modelling indicated that the level of thematic coherence of the initial memory report and ratings of event valence significantly predicted memory consistency at the level of the event. Thematic coherence was a significant negative predictor of content consistency. The findings suggest a developmental progression in the robustness and stability of personal memories between adolescence and young adulthood.     

How are children’s perceptions of the malleability of their academic competencies related to their teachers’ and parents’ views?

The study examined children’s and their parents’ and teachers’ perceptions of the malleability of the child’s academic competencies. A total of 103 third- and sixth-graders and their parents and teachers were asked to rate how much the child could improve her/his competencies in mathematics and Finnish. The participants were asked to use intrapersonal and interpersonal criteria in their ratings, i.e., to rate the child’s potential for improvement in comparison with his/her own current competencies and in relation to her/his peers’ competencies. The results showed a tendency that older children’s perceptions were closer to their parents’ and teachers’ views than those of younger children. Children of academically educated parents showed a stronger correlation with their teachers’ and parents’ intrapersonal perceptions than children of vocationally educated parents. The results also suggested that the teachers and parents trusted in boys’ intrapersonal potential in Finnish more than in girls’ but there were no gender-differences in their perceptions concerning mathematics. In all, the children’s intrapersonal perceptions of their improvement potential were the most optimistic, followed by their parents’ and lastly by their teachers’ perceptions.     

“Owning” the personal past: Adolescents’ and adults’ autobiographical narratives and ratings of memories of recent and distant events

Adults and adolescents are characterised as having different perspectives on their personal or autobiographical memories. Adults are recognised as having vivid recollections of past events and as appreciating the meaning and significance of their autobiographical memories. In development, these qualities are noted as absent as late as adolescence. To evaluate the assumption of developmental differences, we directly compared autobiographical memories of adults and adolescents drawn from each of several periods in the past, using measures of narrative quality (coded independently) and participants’ own subjective ratings of their memories. Adults’ narratives of events from the previous year and for the “most significant” event of their lives were coded as more thematically coherent relative to those of adolescents’; the groups did not differ on thematic coherence of narratives of early-life events (ages 1–5 and 6–10 years). The ratings that adults and adolescents provided of their autobiographical memories were similar overall; differences were more apparent for early-life events than for more recent events and indicated stronger mnemonic experiences among adolescents than adults. The pattern of findings suggests that whereas adults have more sophisticated narrative tools for describing the significance of events and their relation to the corpus of autobiographical memories, adolescents as well as adults have vivid recollective experiences as well as personal and subjective perspective on the events of their lives and their memories thereof.     

Silence is golden? Characteristics and experiences of self-reported whistleblowers

This study investigates the characteristics of whistleblowers, the prevalence and nature of whistleblowing, and the occurrence of retaliation after whistleblowing using a randomly selected and representative sample of Norwegian employees. The results showed that 12 per cent self-reported as whistleblowers according to an operational definition. Being a leader, or a union or personnel safety representative was significantly related to whistleblowing. The most frequently reported wrongdoing was harassment conducted by a single colleague. Wrongdoer(s) received mixed responses, from no reaction to reprimand. Even though most whistleblowers were not sanctioned, they reported less job satisfaction and more workplace bullying than did nonwhistleblowers. Only a few were rewarded. For the most part, wrongdoing was stopped or reduced. However, whistleblowing was only partially effective, because whistleblowers reported lack of feedback about the result of their report. Results also showed that the status of the wrongdoer was related to the reaction he or she received afterwards, as were the type of wrongdoing and the effect on the wrongdoing, and the type of wrongdoing and the effect on the wrongdoer(s). Potential explanations for the results, such as the type of sample and power distance, are discussed. Practical implications of the study are also addressed, such as the importance of providing feedback to whistleblowers.     

Are individuals' reputations related to their history of behavior?

Functional theories of reputation imply that individuals' reputations are tied to their history of behavior. However, indirect evidence suggests that the relation between reputation and behavior might be tenuous at best. In 3 studies, the authors tracked the development of reputations among individuals who engaged in multiple negotiation tasks across several weeks. The authors found that on average, individuals' reputations were only mildly related to their history of behavior. However, the link between reputation and behavior was stronger for some individuals than others--specifically, for individuals who were more well-known and received more social attention in the community. In contrast, for less well-known individuals, their behavior had little impact on their reputation. The findings have implications for psychologists' understanding of reputations, person perceptions in larger groups, and the costs and benefits of social visibility.

How do valence and meaning interact? The contribution of semantic control

The hub-and-spoke model of semantic cognition proposes that conceptual representations in a heteromodal ‘hub’ interact with and emerge from modality-specific features or ‘spokes’, including valence (whether a concept is positive or negative), along with visual and auditory features. As a result, valence congruency might facilitate our ability to link words conceptually. Semantic relatedness may similarly affect explicit judgements about valence. Moreover, conflict between meaning and valence may recruit semantic control processes. Here we tested these predictions using two-alternative forced-choice tasks, in which participants matched a probe word to one of two possible target words, based on either global meaning or valence. Experiment 1 examined timed responses in healthy young adults, while Experiment 2 examined decision accuracy in semantic aphasia patients with impaired controlled semantic retrieval following left hemisphere stroke. Across both experiments, semantically related targets facilitated valence matching, while related distractors impaired performance. Valence congruency was also found to facilitate semantic decision-making. People with semantic aphasia showed impaired valence matching and had particular difficulty when semantically related distractors were presented, suggesting that the selective retrieval of valence information relies on semantic control processes. Taken together, the results are consistent with the hypothesis that automatic access to the global meaning of written words affects the processing of valence, and that the valence of words is also retrieved even when this feature is task-irrelevant, affecting the efficiency of global semantic judgements.
