Eyewitness testimony and memory distortion

Abstract: Do memories change as we acquire new information? Recent research on memory distortion using implicit tests along with research using confidence is reviewed and new studies are presented. Two new studies asked misinformed subjects to provide reasons for their answers. In each study 15% to 27% of subjects said they remembered seeing items they had only read about. In another study subjects were asked to identify the source of misleading items they had seen in slides or read in misleading questions. Subjects were more likely to say they had seen in slides something they read about in the questions than they were to confuse information from two nearly identical sets of slides. Recent work shows that, not only is it possible to distort memory for events, it is possible to implant an entire memory for something that never happened. The evidence is now clear that we can become mentally tricked into making large as well as small changes in the way we recall the past.     

Practical Memory Concerns of Older Adults

We examine practical memory concerns in a sample of community-dwelling older adults. Participants responded to open-ended questions that were designed to solicit information regarding memory self-efficacy, memory management, memory remediation, and fears about memory aging in adulthood. Results indicated that (a) important dates, such as birthdays and anniversaries, were easily remembered, but names were not; (b) external memory aids were used most frequently; (c) a desire to improve memory for names and certain types of verbal information was expressed; and (d) loss of independence emerged as a fear associated with memory aging. Implications of these findings for the design of strategies to improve everyday memory performance and clinical memory management in older adults are discussed.     

Driving without memory: The strength of schema-consistent false memories

Drivers’ memory for their recent trips has been shown to be surprisingly poor, with relatively low accuracy of both recall and recollection and substantial levels of false memories. Driving research has suggested that arousal, such as from risk, leads to more accurate memories. Memory research suggests that the typicality of objects and events makes them harder to remember accurately, compared to schema-inconsistent or atypical objects, and leads to greater likelihood of false memories. In contrast, it has been suggested that memory for actions is different to memory for objects, and that typical actions are remembered more accurately than atypical actions. The present research examined the role of typicality or schema consistency in the accuracy of memory for driving. Participants drove a 15 km route in their own cars and then answered questions about their drive. The results showed that atypical objects and actions were recalled with greater accuracy than typical objects and actions. The results also showed that false memories were most common for typical objects, but not for typical actions. We interpret these results in terms of both memory theory and implications for understanding skilled behaviour such as driving.     

Reflecting on how we remember the personal past: missing components in the study of memory appraisal and theoretical implications

The current paper offers a selective review of the study of memory appraisal, focusing on recollections of the personal past, with the goal to bring attention to a missing component in this study. To date, memory appraisal studies have concentrated on participants’ assessments of the content of their personal recollections (e.g., their perceptual detail and story-like feel), including beliefs about the accuracy of that content. Participants’ assessments of reflection processes accompanying their recollections (e.g., a sense of piecing-together recollection fragments) have yet to be extensively examined. The lack of information on process-based appraisals is related to prior studies’ procedural constraints (e.g., kinds of cue prompts and their timing, minimal opportunities for reflection). Reasons for addressing this missing component provide the central themes of the paper. The reasons emerge from the analysis of autobiographical cueing studies, including integration of narrative research studies and autobiographical works. The analysis leads to suggestions for future research involving the use of personal narratives that are intended to address critiques of reconstruction accounts and unresolved questions in the study of memory appraisal.     

Flexible representations in visual working memory and interactions with long‐term learning: Commentary on the special issue

This special issue of the British Journal of Psychology brings together cutting edge research on a range of topics in visual working memory (VWM). In this commentary, we attempt to summarize common themes in current VWM research exemplified in this issue. The articles include several reviews of important topics as well as empirical papers covering three main themes. The first concerns the nature of mental representations of memoranda in the commonly used delayed estimation task, where both fine‐grained and broad categorical details appear to be represented, and their susceptibility to interference. The second concerns interactions between VWM representations, both those that produce individuation of representations and those that create an overarching ensemble structure. Finally, the third main topic concerns the use of VWM during visual search and in the learning of repeated configurations in search displays. The work presented here, and other work in the field, points to a rich interplay between representations in VWM but also between VWM and information in long‐term memory. Opportunities for further investigation are highlighted throughout.     

Indecent Exposure: Self-objectification and Young Women’s Attitudes Toward Breastfeeding

The sexualization of the breast may lead women who internalize the sexual objectification of their bodies to have more negative attitudes toward breastfeeding. The purpose of the present study was to examine self-objectification in relation to young women’s attitudes toward and concerns about breastfeeding. Two hundred and seventy-five female undergraduates completed a survey with questions that assessed their plans for infant feeding, attitudes toward breastfeeding, concerns about breastfeeding, and self-objectification. Women who scored higher on measures of self-objectification were more likely to view public breastfeeding as indecent and to be concerned that breastfeeding would be embarrassing and would negatively impact their bodies and sexuality. Self-objectification was not related to general attitudes toward breastfeeding or to young women’s future infant feeding plans. Implications for theory and future research are discussed. An earlier version of this study was presented at the annual meeting of the American Psychological Association, Washington, DC (August, 2005).     

Generation disrupts memory for intrinsic context but not extrinsic context

Although generation typically enhances item memory, the effect is subject to a number of theoretically important limitations. One potential limitation concerns context memory but there has been debate about whether generation actually enhances or disrupts memory for contextual details. Five experiments assessed the effect of generation on context memory for perceptual attributes of the study stimulus (intrinsic context). The results indicate that despite enhancing item memory, generation disrupts memory for intrinsic context. This result generalized over different intrinsic details (print colour and font), different generation manipulations, and several methodological factors identified in earlier research as potential moderators of this negative generation effect. Despite the negative generation effect on intrinsic context, contextual details external to the target item (extrinsic context) are not disrupted. In a sixth experiment, a visually based generation task (letter transposition) enhanced context memory for the extrinsic detail of location. Coupled with earlier research, the results indicate that generation disrupts context memory for intrinsic details but either does not harm or enhances memory for extrinsic context.     

Construal Level Theory and Consumer Behavior

The three commentaries on our paper “Construal Levels and Psychological Distance: Effects on Representation, Prediction, Evaluation, and Behavior” offer insightful theoretical extensions and practical applications of construal level theory (CLT). We were inspired and challenged by the commentaries to elaborate on a number of issues, although our elaboration more often raises questions and speculations than provides definite answers. Owing to space limitations, however, we could discuss only some of the issues raised in the commentaries. The first set of issues concerns our theoretical framework, namely, similarities and differences among distance dimensions, the question of additional distances, the nature of the interaction among distances, and the relationship between psychological distance and construct of stimulus information sampling. The second set of issues concerns applications of CLT to consumer choice, namely, how to make better decisions, the nature of regret, and how people construct and process choice sets.     

Knowledge of Memory Aging Across the Lifespan

ABSTRACT. The authors examined knowledge of normal and pathological memory aging in a lifespan sample of 198 individuals who ranged in age from 13 to 88 years. Participants completed the Knowledge of Memory Aging Questionnaire (Cherry, Brigman, Hawley, & Reese, 2003). The authors hypothesized that high school students would be less knowledgeable about memory aging issues than college students, middle-aged, and community-dwelling older adults. Consistent with this hypothesis, response accuracy was lower for high school students compared to their older counterparts. Follow-up analyses revealed that high school students’ responses to a subset of questions that tap ageist views of adult cognition were less accurate than the other age groups, implying a response bias toward stereotypical images of memory aging. Implications for research and the design of instructional materials to increase people's knowledge about normative changes in adult cognition are discussed.     

The response-stimulus contingency and reinforcement learning as a context for considering two non-behavior-analytic views of contingency learning

This paper introduces a special section on the contingency. Bower and Watson were invited to present their views of contingency learning in human infants from outside the context of behavior analysis, and Cigales, Marr, and Lattal and Shahan provided commentaries that point out some of the more interesting and controversial aspects of those views from a behavior-analytic perspective. The debate turns on how to conceptualize the response-stimulus contingency of operant learning. The present paper introduces the contingency concept and contingency detection by subjects, as well as research practices in behavior analysis, in a context in which the dependency between infant responding and the presentation of environmental consequences may be disrupted through procedures in which ordinarily consequent events occur before the response or in its absence. These points can relate to and serve as an introduction to the Bower and Watson papers on infant contingency learning as well as to the three commentaries that follow.     

Collective interviewing: A transactive memory approach towards identifying signs of truthfulness

Group interviewing has been neglected in the deception literature, yet it coincides with recent collective memory research. The present experiment applied the transactive memory theory to a collective interviewing situation and explored whether signs of truthfulness emerged through measuring joint memory recall. Truth-tellers were real couples who had been in a relationship for at least one year and cohabiting. Lying pairs were friends who pretended to be in a relationship for at least one year and cohabiting. All couples were interviewed in their pairs about their ‘real’ or ‘fictitious’ relationships. It was found that truth-telling pairs posed questions to one another, provided cues to one another, handed over remembering responsibility, and finished each others’ sentences significantly more than lying pairs, supporting the idea that real couples have a transactive memory system, unlike pretending couples. Implications for a collective interview approach that considers memory within deception detection are discussed.     

Freshman flashbulbs: Memories of unique and first-time events in starting college

Students from the Lafayette Class of 2011 (N=100) described events that occurred during their transition to college. Three were unique events (receiving their acceptance letter, being left alone on campus, and taking the class photograph) and three were first-time experiences (first seeing their dorm room, meeting their roommate, and attending their first college class). The definitional criteria for flashbulb memories (FBM) was met for all six events; memory reports included what participants were doing, where they were, who they were with, the emotions they experienced, and other idiosyncratic details. Therefore, transitional events are a productive analogue for traditional FBM research. Unique events were rated as more emotional and significant than first-time events, yet both were recalled with similarly enhanced vividness and confidence and both included similar content. Extensions of this method to investigations of other open questions in FBM research are discussed.     

But what does it mean in practice? The Journal of Occupational and Organizational Psychology from a practitioner perspective

The author offers some personal reflections on the relevance of the Journal of Occupational and Organizational Psychology (JOOP) to human resource (HR) practitioners. Suggestions are made for how JOOP articles could be more relevant, and how their relevance could be made more explicit. These include (i) framing the research questions/hypotheses in terms that appeal to practitioner concerns as well as theoretical issues, (ii) more analysis of practical implications in the discussion section, (iii) more use of target articles with commentaries rather than special issues/sections, (iv) redirection of articles that focus primarily on method or instrument development to other journals and (v) making use of the World Wide Web. The arguments are illustrated with reference to papers recently published in JOOP.     

The relationships between perceived control and episodic memory in adulthood: a review

The goal of the current paper is to review the literature on the relationships between perceived control and episodic memory throughout adulthood. More specifically, three major questions are pursued: (1) Are higher levels of perceived control related to better memory performance? (2) Is the relationship between perceived control and memory similar or different as a function of age? (3) Does perceived control moderate memory decline? Although there is a great deal of evidence that perceived control and episodic memory are positively related in adulthood, the current review showed that very few studies have investigated whether age moderated this relationship. Moreover, only a limited number of studies have explored the role of perceived control in memory decline, and the results are inconsistent. We suggest some avenues for future research that could help understand by which mechanisms, and under what circumstances, perceived control and episodic memory are related across the lifespan.

Accessibility and characteristics of memories of the future

Recent research suggests that some imagined future events are encoded in memory, leading to the formation of “memories of the future”. However, questions remain regarding the exact components of future event simulations that are encoded and the factors that determine their accessibility. To address these questions, the present study investigated memory for previously imagined future events using both free and cued recall tasks. The results showed that most future event simulations were successfully encoded and remained available in memory after a one week delay, but only some of them were readily accessible, whereas others could only be accessed when relevant cues were provided. Persons and locations were particularly well remembered, suggesting that these components are central to the simulation and memorisation of future events. We also found that memory for future event simulations was related to the clarity and familiarity of represented persons, the subjective feelings of pre-experience and mental time travel, the importance of imagined events to personal goals, and their emotional intensity during the initial simulation phase. Taken together, these findings expand our understanding of the formation, accessibility, and characteristics of memories of the future.     

Predictors of Subjective Memory in Young Adults

While the nature of memory complaints during older adulthood has been studied extensively, the meaning of subjective memory concerns in younger adults has not been fully addressed. Using a sample of 95 younger adults, this study examined the role of personality, health, and depression in predicting objective and subjective memory. For objective memory, openness and self-rated health were unique predictors. For subjective memory ability, only self-rated health was predictive. Finally, similar to studies with older adults, neuroticism and conscientiousness were predictive of both perceived frequency of forgetting and global memory. Using subjective memory concerns as an indicator of actual memory functioning may be inappropriate given the extent to which personality traits and health predict memory concerns.     

Adaptive Memory: Remembering With a Stone-Age Brain

ABSTRACT— If memory evolved, sculpted by the processes of natural selection, then its operating characteristics likely bear the "footprints" of ancestral selection pressures. Psychologists rarely consider this possibility and generally ignore functional questions in their attempt to understand how human memory works. We propose that memory evolved to enhance reproductive fitness and, accordingly, its systems are tuned to retain information that is fitness-relevant. We present evidence consistent with this proposal, namely that processing information for its survival relevance leads to superior long-term retention—better, in fact, than most known memory-enhancement techniques. Even if one remains skeptical about evolutionary analyses, adopting a functional perspective can lead to the generation of new research ideas.
