Genetics and personality affect visual perspective in autobiographical memory

Major depression is associated with a decrease of 1st person (versus 3rd person) visual perspective in autobiographical memory, even after full remission. This study aimed to examine visual perspective in healthy never-depressed subjects presenting with either genetic or psychological vulnerability for depression. Sixty healthy participants performed the Autobiographical Memory Test with an assessment of visual perspective. Genetic vulnerability was defined by the presence of at least one S or L_G allele of the polymorphism of the serotonin-transporter-linked promoter region (5-HTTLPR). Psychological vulnerability was defined by high scores of harm avoidance measured by the Temperament and Character Inventory. Life stress exposure, depressive mood, rumination, and familial history of depression were assessed through standardized procedures. Visual perspective for positive memories was independently predicted by both harm avoidance and a gene by environment interaction between the 5-HTTLPR polymorphism and life stress exposure. Visual perspective and vulnerability for depression may share some biological bases.     

The biology of visual perspective and depression: A reply to Sutin

A recent meta-analysis by Munafò, Durrant, Lewis, and Flint (2009) [Munafò, M. R., Durrant, C., Lewis, G., & Flint, J. (2009). Gene × environment interactions at the serotonin transporter locus. Biological Psychiatry, 65, 211–219] questioned the meaning of studies searching for endophenotypes associated with the serotonin-transporter-linked promoter region (5-HTTLPR) polymorphism, including our study on visual perspective during autobiographical memory retrieval. However, the association of 3rd person perspective with vulnerability for depression does not rely only on genetics. External consistency is provided by the influence of the 5-HTTLPR polymorphism on brain regions involved in emotion regulation and autobiographical memory retrieval (e.g. the medial prefrontal cortex). Internal consistency is provided by the increased prevalence of 3rd person perspective in both currently and previously depressed patients, as well as in depression-prone individuals. Further studies should examine therapeutic opportunities.     

When the "I" looks at the "Me": autobiographical memory, visual perspective, and the self

This article presents a theoretical model of the self processes involved in autobiographical memories and proposes competing hypotheses for the role of visual perspective in autobiographical memory retrieval. Autobiographical memories can be retrieved from either the 1st person perspective, in which individuals see the event through their own eyes, or from the 3rd person perspective, in which individuals see themselves and the event from the perspective of an external observer. A growing body of research suggests that the visual perspective from which a memory is retrieved has important implications for a person’s thoughts, feelings, and goals, and is integrally related to a host of self-evaluative processes. We review the relevant research literature, present our theoretical model, and outline directions for future research.     

Observer memories may not be for everyone

ABSTRACT

Six studies explored the preponderance of people who experience third-person perspective observer memories during autobiographical memory retrieval. The concept of first-person field versus observer memories has been extensively used in the areas of cognitive, social, and clinical psychology. An implicit assumption is the idea that most people use both of these perspectives. What varies are the circumstances that bias people to use one perspective over another for a given autobiographical memory. We challenge that assumption across six studies by showing that, while there are some people who report to regularly have observer memories, there are also those that report to rarely or never have them. These reports were found to be related to levels of reported dissociative experiences. We discuss how this difference in the experience of observer memories may also reflect other innate characteristics, and may correspond to predispositions for various pathologies, including depression, social phobia, and post-traumatic stress disorder.     

Scientific creativity as constrained stochastic behavior: the integration of product,person, and process perspectives

Psychologists have primarily investigated scientific creativity from 2 contrasting in vitro perspectives: correlational studies of the creative person and experimental studies of the creative process. Here the same phenomenon is scrutinized using a 3rd, in vivo perspective, namely, the actual creative products that emerge from individual scientific careers and communities of creative scientists. This behavioral analysis supports the inference that scientific creativity constitutes a form of constrained stochastic behavior. That is, it can be accurately modeled as a quasi-random combinatorial process. Key findings from both correlational and experimental research traditions corroborate this conclusion. The author closes the article by arguing that all 3 perspectives--regarding the product, person, and process--must be integrated into a unified view of scientific creativity.     

The relation of moral orientation and moral judgment to prosocial and antisocial behaviour of Chinese adolescents

The present study investigated the relation of moral orientation and moral judgment to prosocial and antisocial behaviour from a first‐person perspective. The major findings support the following four hypotheses. (la) The moral orientation of girls is higher than that of boys, and (1b) boys are more delinquent than girls; (2) the moral orientation of prosocial adolescents is higher than that of delinquent adolescents; (3) the moral judgment of prosocial adolescents is higher than that of delinquent adolescents; and (4) the moral development of prosocial adolescents is higher than that of delinquent adolescents. Few researchers have attempted to investigate how moral orientation and moral judgment relate to prosocial and antisocial behaviour in a single study. The present study fills this research gap. Moreover, the study of moral judgment from a first‐person perspective appears to be a meaningful and useful approach. Future studies should be conducted to investigate whether moral judgment from a first‐person perspective is more predictive of moral behaviour than moral judgment from a third‐person perspective. It would also be meaningful to conduct a cross‐cultural study to investigate the relation of moral orientation and moral judgment to prosocial and antisocial behaviour in different cultures. The use of a self‐report method in a study of prosocial and antisocial behaviour has certain limitations; for example, respondents may not give honest responses. However, this method has been found to be useful and acceptable, especially for researching the correlations among a large number of variables.     

How long is your arm? Using multisensory illusions to modify body image from the third person perspective

Updating body representations from the 3rd person perspectives (3PP) seems to require viewing the real body, unlike when viewing from a 1st person perspective. Here, 3PP updating was investigated through induction of a physically impossible multisensory illusion in which participants viewed real-time 3PP video of themselves having their arm pulled until it stretched to twice its normal length. The illusion elicited the subjective experience that the participant's own arm had been stretched and caused an overestimation of reaching distance, although actual reaches were unaffected. Multisensory illusions from the 3PP can alter body image when applied to real bodies.     

I can see it both ways: First- and third-person visual perspectives at retrieval

The number of studies examining visual perspective during retrieval has recently grown. However, the way in which perspective has been conceptualized differs across studies. Some studies have suggested perspective is experienced as either a first-person or a third-person perspective, whereas others have suggested both perspectives can be experienced during a single retrieval attempt. This aspect of perspective was examined across three studies, which used different measurement techniques commonly used in studies of perspective. Results suggest that individuals can experience more than one perspective when recalling events. Furthermore, the experience of the two perspectives correlated differentially with ratings of vividness, suggesting that the two perspectives should not be considered in opposition of one another. We also found evidence of a gender effect in the experience of perspective, with females experiencing third-person perspectives more often than males. Future studies should allow for the experience of more than one perspective during retrieval.     

The Influence of Motor Imagery on Postural Sway: Differential Effects of Type of Body Movement and Person Perspective

The present study examined the differential effects of kinesthetic imagery (first person perspective) and visual imagery (third person perspective) on postural sway during quiet standing. Based on an embodied cognition perspective, the authors predicted that kinesthetic imagery would lead to activations in movement-relevant motor systems to a greater degree than visual imagery. This prediction was tested among 30 participants who imagined various motor activities from different visual perspectives while standing on a strain gauge plate. The results showed that kinesthetic imagery of lower body movements, but not of upper body movements, had clear effects on postural parameters (sway path length and frequency contents of sway). Visual imagery, in contrast, had no reliable effects on postural activity. We also found that postural effects were not affected by the vividness of imagery. The results suggest that during kinesthetic motor imagery participants partially simulated (re-activated) the imagined movements, leading to unintentional postural adjustments. These findings are consistent with an embodied cognition perspective on motor imagery.     

Remembering from any angle: the flexibility of visual perspective during retrieval

When recalling autobiographical memories, individuals often experience visual images associated with the event. These images can be constructed from two different perspectives: first person, in which the event is visualized from the viewpoint experienced at encoding, or third person, in which the event is visualized from an external vantage point. Using a novel technique to measure visual perspective, we examined where the external vantage point is situated in third-person images. Individuals in two studies were asked to recall either 10 or 15 events from their lives and describe the perspectives they experienced. Wide variation in spatial locations was observed within third-person perspectives, with the location of these perspectives relating to the event being recalled. Results suggest remembering from an external viewpoint may be more common than previous studies have demonstrated.     

Mood-dependent retrieval in visual long-term memory: dissociable effects on retrieval probability and mnemonic precision

Although memories are more retrievable if observers’ emotional states are consistent between encoding and retrieval, it is unclear whether the consistency of emotional states increases the likelihood of successful memory retrieval, the precision of retrieved memories, or both. The present study tested visual long-term memory for everyday objects while consistent or inconsistent emotional contexts between encoding and retrieval were induced using background grey-scale images from the International Affective Picture System (IAPS). In the study phase, participants remembered colours of sequentially presented objects in a negative (Experiment 1a) or positive (Experiment 2a) context. In the test phase, participants estimated the colours of previously studied objects in either negative versus neutral (Experiment 1a) or positive versus neutral (Experiment 2a) contexts. Note, IAPS images in the test phase were always visually different from those initially paired with the studied objects. We found that reinstating negative context and positive context at retrieval resulted in better mnemonic precision and a higher probability of successful retrieval, respectively. Critically, these effects could not be attributed to a negative or positive context at retrieval alone (Experiments 1b and 2b). Together, these findings demonstrated dissociable effects of emotion on the quantitative and qualitative aspects of visual long-term memory retrieval.     

Visual imagery in autobiographical memory: The role of repeated retrieval in shifting perspective

Recent memories are generally recalled from a first-person perspective whereas older memories are often recalled from a third-person perspective. We investigated how repeated retrieval affects the availability of visual information, and whether it could explain the observed shift in perspective with time. In Experiment 1, participants performed mini-events and nominated memories of recent autobiographical events in response to cue words. Next, they described their memory for each event and rated its phenomenological characteristics. Over the following three weeks, they repeatedly retrieved half of the mini-event and cue-word memories. No instructions were given about how to retrieve the memories. In Experiment 2, participants were asked to adopt either a first- or third-person perspective during retrieval. One month later, participants retrieved all of the memories and again provided phenomenology ratings. When first-person visual details from the event were repeatedly retrieved, this information was retained better and the shift in perspective was slowed.     

Visual perspective in autobiographical memories: Reliability,consistency, and relationship to objective memory performance

Visual perspective in autobiographical memories was examined in terms of reliability, consistency, and relationship to objective memory performance in a sample of 99 individuals. Autobiographical memories may be recalled from two visual perspectives—a field perspective in which individuals experience the memory through their own eyes, or an observer perspective in which individuals experience the memory from the viewpoint of an observer in which they can see themselves. Participants recalled nine word-cued memories that differed in emotional valence (positive, negative and neutral) and rated their memories on 18 scales. Results indicate that visual perspective was the most reliable memory characteristic overall and is consistently related to emotional intensity at the time of recall and amount of emotion experienced during the memory. Visual perspective is unrelated to memory for words, stories, abstract line drawings or faces.     

Nonbelieved memories in middle-aged and older people

Previous studies have reported that young participants typically date events that they remember, but no longer believe they experienced, to the period of childhood. The present study investigated whether participants aged between 40 and 79 years dated events related to relinquished memories to the period of childhood, as do younger people, or whether they dated such events to a period later in life. The study also compared believed and nonbelieved memories with respect to memory perspective (1st vs 3rd person perspective). Results indicated that the majority of middle-aged and older people dated nonbelieved memories to the period of childhood (median age = 8 years). No correlation was found between the participants’ current age and their age at the time the nonbelieved event occurred. In addition, results showed that believed memories were more likely to be retrieved from a 1st person perspective than were nonbelieved memories.     

Emotion and vantage point in autobiographical

Autobiographical memories may be recalled from two different perspectives: Field memories in which the person seems to remember the scene from his/her original point of view and observer memories in which the rememberer sees him/herself in the memory image. Here, 122 undergraduates participated in an experiment examining the relation between field vs. observer perspective in memory for 10 different emotional states, including both positive and negative emotions and emotions associated with high vs. low intensity. Observer perspective was associated with reduced sensory and emotional reliving across all emotions. This effect was observed for naturally occurring memory perspective and when participants were instructed to change their perspective from field to observer, but not when participants were instructed to change perspective from observer to field.     

不同感觉功能对抑郁的影响及其神经机制

大脑通过视觉、听觉、嗅觉、味觉和触觉等感官通道接收来自外界的信息。不同感觉功能受损涉及抑郁发生的中枢机制,而基于不同感官通道进行适当刺激以及多感官联合干预也可能发挥显著的抑郁治疗作用。笔者以症状-脑区-机制-治疗为逻辑主线,首次系统梳理了五种主要感觉障碍人群的抑郁临床症状、抑郁神经机制以及基于感觉刺激的抗抑郁治疗。结果表明,不同感觉功能障碍对抑郁相关神经机制的影响可能表征了不同的抑郁病理,涉及神经元电活动(某些神经元放电和神经环路激活等)和神经生化改变(神经可塑性和神经发生、炎症免疫和HPA轴、神经激素和神经递质等),且主要发生在边缘系统及其附近脑区,涉及岛叶、颞叶、额叶等。因此,未来研究可聚焦于机体对不同感觉信息的提取,这将为人类抑郁的病因和治疗提供新的研究视角。     

Motivated self and recall: visual perspectives in remembering past behaviors

The present study examined motivational influences on visual perspectives in remembering past events and behaviors. Participants were first induced to believe that extraversion or introversion is conducive of success. Next, they recalled in details two introverted past behaviors. Introversion‐success participants, presumably motivated to see themselves as introverted, recalled and visualized the behaviors more from a first‐person actor perspective than did extraversion‐success participants (who recalled the behaviors from a third‐person observer perspective). Remembering past behaviors from a first‐person actor perspective implies that the behaviors are true of the self and impacts self‐definition to a relatively greater degree. The findings thus extend the influence of desired self to how people remember past events. They also contribute to the integration of motives in research on the link between self‐inferences and the subjective experience of remembering. Copyright © 2007 John Wiley & Sons, Ltd.

Learning and memory for personality prototypes

Although personality traits are commonly assumed to be represented in memory as schemata, little research has addressed whether such schemata can be learned from observation. Subjects in three studies classified 60 person instances into group members and nonmembers as defined by the instances' match to a complex personality prototype. To simulate learning of fuzzy categories, each person instance provided conflicting cues to group membership. Learning for instances' group membership was excellent across studies. In Study 1, frequency of cues indicating group membership was greatly overestimated among nongroup instances. In Study 2, schema-consistent memory bias was revealed for person instances. In Study 3, schemata of consistently positive (or negative) traits were learned faster than arbitrary schemata. The findings implicated frequency sensitivity of memory (Estes, 1986), and a model of probabilistic cued-memory retrieval was developed to account for the effects. The findings were then discussed in relation to everyday cognitive performance.     

Now I see it but you don't: 14-month-olds can represent another person's visual perspective

Twelve- and 14-month-old infants' ability to represent another person's visual perspective (Level-1 visual perspective taking) was studied in a looking-time paradigm. Fourteen-month-olds looked longer at a person reaching for and grasping a new object when the old goal-object was visible than when it was invisible to the person (but visible to the infant). These findings are consistent with the interpretation that infants 'rationalized' the person's reach for a new object when the old goal-object was out of sight. Twelve-month-olds did not distinguish between test conditions. The present findings are consistent with recent research on infants' developing understanding of seeing.
