Not too ‘shy’ to help catch a thief: Recall memory of shy versus non-shy witnesses

Witness shyness was examined to determine its impact on recall accuracy in two experiments. It was hypothesized that shyness would facilitate witness accuracy, under some conditions. In Experiment 1, witnesses were asked to respond to directed recall questions probing crime event and culprit details. Non-shy and shy witnesses produced comparable accuracy rates when describing the culprit. In contrast, non-shy witnesses were more accurate when describing crime environment details than shy witnesses. In Experiment 2, arousal was manipulated and a free recall approach was used to assess recall accuracy. Under low arousal, shy witnesses were more accurate at describing the culprit than non-shy witnesses, whereas, non-shy witnesses were more accurate at describing crime details than shy witnesses. Under high arousal, differences in accuracy were not observed across shy and non-shy witnesses.     

Recall of details never experienced: Effects of age,repetition, and semantic cues

To test theoretical predictions about the role of meaning connections in false memory, the effects of semantic cues and list repetition on children's false memories were evaluated across early childhood to mid-adolescence using the Deese–Roediger–McDermott (DRM) paradigm. True recall and false recall increased from 7 to 13 years. Study list repetition increased true recall of list words with the magnitude of this effect largest in the older children and adolescents. Repetition reduced false recall of critical lures in all age groups. Consistent with theoretical predictions, false recall of critical lures increased when children were informed of the thematic gist of each list prior to study.     

Interference with prior knowledge while writing from sources: Effects of working memory capacity

Writing from sources requires the processing of both external (documentary) and internal (long-term memory; LTM) sources of information, which can sometimes interfere with each other. We hypothesised that writers with high working memory (WM) capacity would resolve interference faster than those with low-capacity WM. However, results showed that writing pause duration was shorter for low-capacity writers. This result suggests that when WM resources are limited, access to domain knowledge in LTM is restricted, thereby avoiding interference between the two sources. Results are discussed within the broader context of text composition from sources and individual differences.     

The strategic regulation of children's memory performance and suggestibility

We report two empirical studies that investigated previously reported benefits of a high accuracy motivation, and thus a high threshold, for children's and adults' event recall and for their ability to resist false suggestions. In the studies, 6-, 7-, and 8-year-olds, as well as adults, were shown a brief video about an event and were later asked unbiased and misleading questions about it. In Study 1, participants were either (a) given the typical accuracy instructions (including the option to answer with "I don't know"), (b) reminded of the accuracy instructions during the interview, or (c) immediately given feedback and a token for every correct answer. The results showed that the reminders were ineffective in stimulating strategic control behavior in children, independent of age. In Study 2, the confounding effects of feedback and incentives were disentangled by contrasting (a) free report, (b) feedback only, (c) incentives only, and (d) feedback plus incentives. Analyses on recall performance and suggestibility revealed that both feedback and incentives are necessary to increase children's accurate memory reports.     

Effects of Guided Notes on University Students' Responding and Recall of Information

The present study assessed the effects of guided notes on student responding and accuracy of recall of lecture material in an undergraduate psychology class using multi-element design. Guided notes were administered for approximately half of the class sessions on a random schedule. Data were collected on the frequency of student responses and daily quizzes were administered to assess accuracy of recall of information presented in the lecture. Results indicated higher mean quiz scores and response frequencies during the guided notes condition. Social validity questionnaires administered to participants revealed satisfaction with results and procedures.     

Manipulations of start and food locations affect navigation on a foraging task

Rats were able to search multiple food cups in a foraging task and successfully return to a fixed, but not a variable, start location. Reducing the number of food cups to be searched resulted in an improvement in performance in the variable start condition. Performance was better when only one or two food cups had to be visited but was still impaired if the food was not found in the first cup searched. Variable start locations impaired performance when only one food cup had to be searched, if that cup was moved over the table. These findings suggest that there is an interaction between memory processes and the navigational processes that allows an animal to return to its start location after a foraging trip. It appears that a fixed location for the food or the start point of a foraging trip is a necessary precondition for accurate performance.     

Tracking the Time Course of Word‐Frequency Effects in Auditory Word Recognition With Event‐Related Potentials

Although the word‐frequency effect is one of the most established findings in spoken‐word recognition, the precise processing locus of this effect is still a topic of debate. In this study, we used event‐related potentials (ERPs) to track the time course of the word‐frequency effect. In addition, the neighborhood density effect, which is known to reflect mechanisms involved in word identification, was also examined. The ERP data showed a clear frequency effect as early as 350 ms from word onset on the P350, followed by a later effect at word offset on the late N400. A neighborhood density effect was also found at an early stage of spoken‐word processing on the PMN, and at word offset on the late N400. Overall, our ERP differences for word frequency suggest that frequency affects the core processes of word identification starting from the initial phase of lexical activation and including target word selection. They thus rule out any interpretation of the word frequency effect that is limited to a purely decisional locus after word identification has been completed.     

The Differential Effects of Right‐Wing Authoritarianism and Social Dominance Orientation on Political Intolerance

Decades of scholarship have identified several determinants of political intolerance, including authoritarianism and normative threat. Previous attempts in the literature to associate other individual difference variables (i.e., social dominance orientation [SDO]) and situational variables (i.e., out‐groups' gains in power and status) have been unsuccessful. Using a dual‐process motivational (DPM) model framework, in Study 1 we found that SDO predicted political intolerance of groups with hierarchy‐attenuating political objectives. This relationship was consistent over and above other well‐known predictors of political intolerance, including right‐wing authoritarianism (RWA). RWA predicted intolerance of groups with both hierarchy‐attenuating and cohesion‐reducing objectives. In Study 2, we manipulated whether an immigrant‐rights group was described as presenting a normative threat or as gaining power and status. Consistent with extant findings, RWA moderated the effect of normative threat on political intolerance. More interestingly, SDO moderated the effect of gains in power and status on political intolerance. The implications of these findings are discussed.     

Eyewitness Testimony: The Effects of Discussion on Recall Accuracy and Agreement

While some previous research has suggested that group discussion may facilitate eyewitness accuracy, other research has drawn attention to the potential dangers of such discussion. The present studies examine this controversy and the interaction between accuracy and agreement following group discussion. It was found that individuals tend to agree in their testimony following group discussion, and are liable to change their original replies to bring themselves into agreement with group leaders' recall. A second experiment focused upon the actual items which witnesses agreed on following discussion. Changing the mode of questioning from interrogative to narrative eliminated differences in magnitude of agreement between discussion and no-discussion groups. As narrative recall leads to reporting of "easy" items, it was suggested that only certain "difficult" items are susceptible to discussion effects. The need for caution regarding the reliance on testimony following witness discussion was stressed.     

Failing to Recall: Examining the Effects of Trace Decay and Interference on Memory for Campaign Information

Voters are continuously bombarded with information during political campaigns, yet a consistent conclusion from research on voter learning is that individuals remember far less information about political candidates than one might expect. What remains unclear is why memory for campaign information is so poor. The present study examines two explanations for memory failure. Using an experimental design, the present study explores whether campaign information fades from memory (trace decay) or whether extraneous information impedes an individual's subsequent ability to recall campaign information (interference). The results suggest that examining the ways in which the larger information environment influences recall of campaign information has important implications for the importance we attribute to campaign information in models of voter decision making.     

The Effects of Self-generated Cues on Recall of the Paragraphs of a Text

A self-generated list of short indications of the paragraphs of a text was shown to subjects to facilitate the retrieval of the text's contents during recall. The results of Experiment 1 indicated that a substantial number of potentially accessible paragraphs failed to be retrieved under ordinary conditions of free recall. Access to some paragraphs appears to have been inhibited progressively by previous, more or less complete, retrieval of the contents of other paragraphs. In Experiment 2, repetition of recall provided access to a significant number of supplementary paragraphs. A significant number of paragraphs initially reproduced, however, was omitted during secondary recall. In both experiments, the completeness of recalled paragraphs was a negative function of their serial position of output. In Experiment 3, inspection of a self-generated list of short indications of paragraphs and experimenter-provided verbal embellishment of half of the paragraphs affected recall independently.     

Effects of gaze‐aversion on visual‐spatial imagination

Research suggests that averting gaze from an interlocutor can improve both children's and adults' performance in a range of cognitive tasks. With the present experiments, we investigated the effect of gaze aversion on adults' visual‐spatial imagination, using a methodology adapted from Kerr (1987). Participants mentally kept track of a pathway through an imaginary matrix, while either maintaining eye‐contact with the experimenter, closing their eyes, gazing at a static or a dynamic visual stimulus (in Experiment 1), or fixating an upright or inverted image of the experimenter's face (in Experiment 2). The results show that whereas maintaining eye‐contact with another person disrupts accurate imagination of this pathway, averting gaze or looking at other visual stimuli does not. We conclude that gaze aversion benefits cognitive performance, not just by disengaging visual attention from irrelevant visual information, but also by interrupting social interaction processes involved in face‐to‐face communication.     

预警和呈现时间对错误再认和错误回忆的影响

采用DRM范式,通过两个实验探讨了学习阶段的预警和词表呈现时间对错误再认与错误回忆的影响异同以及其发生作用的可能条件.采用视觉-视觉通道的学习-测验模式,实验1使用再认测验,结果发现呈现时间对错误再认不存在影响,而预警提示有效地降低了错误再认;实验2使用回忆测验,依然没有发现呈现时间对错误回忆的影响效应,预警的效应也消失.以上结果表明:(1)预警对错误回忆的影响受到编码时呈现通道的影响,视觉编码条件下预警效果甚微,而错误再认则无此通道效应;(2)呈现时间的较大变化可同时促进激活与监测过程,错误记忆效应的大小是激活与监测双加工过程此消彼长的交互作用结果.     

A Comparison of the Effects of Positive and Negative Information on Job Seekers' Organizational Attraction and Attribute Recall

To date there have been no direct studies of how strong negative information from sources outside of organizations' direct control impacts job seekers' organizational attraction. This study compared models for positive and negative information against a neutral condition using a longitudinal experimental study with college-level job seekers (n = 175). Consistent with the accessibility-diagnosticity perspective, the results indicated that negative information had a greater impact than positive information on job seekers' organizational attraction and recall, and this effect persisted 1 week after exposure. The results did not indicate that the influence of information sources and topics that fit together was lessened when the information was negative. The results suggest that job seekers interpret positive and negative information differently and that negative information, when present, has an important influence on job seekers' organizational attraction.     

Supplementary Fit,Complementary Fit,and Work‐Related Outcomes: The Role of Self‐Construal

The current research investigated whether employees' self‐construals moderated the effects of supplementary fit and complementary fit on their work‐related outcomes (i.e. affective commitment and citizenship behavior). An organisational sample of 317 Chinese employees provided evidence that the relations between supplementary fit and these two work‐related outcomes were stronger among employees with a higher interdependent self‐construal. Conversely, the relations between complementary fit and work‐related outcomes were stronger among employees with a higher independent self‐construal. Theoretical and practical implications of these findings are discussed.     

Effects of mothers’ conversation style and receipt of misinformation on children's event reports

Can memory sharing conversations with mothers lead to errors in children's event memory when mothers are exposed to misinformation about what their children experienced and does this effect vary as a function of maternal memory-sharing style? Mothers were exposed to a false suggestion about a non-shared event and then discussed that event with their children. When later interviewed, those children whose mothers were provided this misinformation were likely to wrongly report experiencing activities consistent with the maternal suggestion and embellish their reports of these activities with elaborative detail. Moreover, children whose mothers spoke in a highly elaborative manner were more likely to recall occurrences in line with the maternal suggestion and provided more fictitious narrative detail describing non-occurring-but-suggested information than did children whose mothers used a less elaborative style. These findings suggest that when mothers hold false beliefs about a non-shared event, an elaborative maternal style is associated with an increase in children's false reports reflecting maternal beliefs.     

The Effect of Disruptions During Counseling on Recall of Genetic Risk Information: The Case of Cystic Fibrosis

Genetic counseling is a communication process with two main functions: information provision and supportive counseling. The information transmission function may be compromised by disruptions that occur during counseling. At least two mediators are possible: (a) disruptions may interfere with memory by creating distractions and divided attention during encoding or (b) disruptions may degrade the flow of interaction which requires that participants engage in conversation repair rather than the task at hand. This study examined both alternatives in a group of parents (N=20 families, 40 individual parents) whose infant had received a newborn screening for cystic fibrosis (CF). Upon arrival at the hospital, each parent completed a questionnaire designed to assess his or her knowledge of CF. Their interaction with the genetic counselor was videotaped and coded for the presence of disruptions. Six weeks after the counseling, parents again completed the knowledge measure. The data showed a direct negative effect for disruptions during counseling on memory for CF-related risk information six weeks later. Disruptions also produced the anticipated effect on conversation, but counter to expectations, interruptions of conversation flow was positively associated with knowledge at time 2.     

The Impact of Self‐Affirmation on Health Cognition,Health Behaviour and Other Health‐Related Responses: A Narrative Review

There is growing evidence that self‐affirmation – the process of reflecting upon cherished values or attributes – may have implications for health. Postulated effects range from reducing the defensive resistance to unwelcome health‐risk information to ameliorating the physiological response to stress. In this, the first detailed review of the literature on self‐affirmation and health, we summarise what is known. Self‐affirming can increase acceptance of unwelcome health‐risk information, especially among those at greatest risk. Self‐affirmed participants typically also report more intention to change behaviour postmessage. There is evidence that certain effects of self‐affirming may endure. Self‐affirmation has also been shown to have beneficial effects on the response to stress. There is, however, currently only limited evidence of actual health‐behaviour change following self‐affirmation. We discuss reasons for this and consider key research questions for the next phase of research.
