Eyewitness Memory and Metamemory in Product Identification: Evidence for Familiarity Biases

Research on the reliability of eyewitness memory for criminal events has been extensively studied, but eyewitness memory in civil cases has not. However, many of these civil cases revolve around eyewitness memory for events that transpired decades ago. We have developed a paradigm with which to study memory for specific product brand identification, a common question in civil cases involving product liability. Participants were asked to follow recipes and were then given surprise memory tests on the specific brands of products used. In addition, they were asked to report their subjective confidence for each response. Memory and performance was poor after even a brief delay, as was metamemory accuracy: Confidence regarding brand name recall was a poor indicator of accuracy. Participants also displayed a strong familiarity bias. They frequently reported using familiar, common brands, when no such products were actually used. This was especially true at longer delays, after which false identification of familiar products was twice as common as correct responses.     

Contextual Connections Within Puns: Effects on Perceived Humor and Memory

The supposition that perceived humor or cleverness would be enhanced by adding separate content to the alternative meanings of a pun was explored, using Tom Swifties as the research vehicle. Because detecting a punning word relationship might induce arousal, requiring more effort and attentional resources for processing than noting a contextual connection, memory strength for adverbs was also examined using a recognition procedure. Five studies were conducted in which college students were asked to judge 24 Swifties (content counterbalanced across participants) in which presence of pun and context were manipulated. The punning relationship was primarily responsible for perceived humor and cleverness. Presence of a pun also enhanced memory strength (d') as long as the familiarization task focused on humor and cleverness. Coherent context enhanced perceived cleverness inconsistently. It was suggested that a coherent contextual connection may make a greater contribution in more lengthy forms of pun-based word play, such as fables or “shaggy dog” stories.     

Filial Obligations: A Contextual, Pluralist Model

In this article I investigate the nature and extent of filial obligations. The question what (adult) children owe their parents is not only philosophically interesting, but also of increasing relevance in ageing societies. Its answer matters to elderly people and their adult children, and is relevant to social policy issues in various ways. I present the strongest arguments for and against three models of filial obligations: the ??past parental sacrifices?? model, the ??special relationship?? model, and the conventionalist model. There is something to be said??and after consideration of objections something remains to be said??for all three models. In other words: filial obligations have more than one source, and an adequate model of filial obligations should reflect this. On its own, each of the above models is one-sided. They also fail to show the connections between the question of filial obligations and various other issues, such as issues of gender justice, the extent of institutionalization of eldercare, and social conventions regarding filial responsibility. Therefore, I integrate what I think we should keep from the aforementioned models into a contextual, pluralist model, which places filial obligations in a broader social and cultural context and relates them to issues of social justice. The model also highlights the difference between general and specific filial obligations, and the factors that determine their nature and extent, thus enabling a deeper and more comprehensive understanding of filial obligations.     

Perceived Overqualification: A Multi-Source Investigation of Psychological Predisposition and Contextual Triggers

ABSTRACT. Although employee (subjective) perceived overqualification (POQ) has recently been explored as a meaningful organizational construct, further work is needed to fully understand it. We extend the theoretical psychological underpinnings of employee POQ and examine both its determinants and outcomes based on established and newly proposed theoretical developments. Four-hundred and fifteen employees completed an online questionnaire and 208 of their supervisors completed corresponding surveys about the employees’ withdrawal behaviors and job-related attitudes, in order to explore potential predictors and outcomes of subjectively experienced POQ. Among the predictors, work conditions (uniform requirements and repetitive tasks) were most strongly associated with POQ. In terms of individual differences, narcissism predicted higher POQ while general mental ability only did when holding other variables constant. In addition, among the outcomes, higher POQ was related to lower job satisfaction and organizational commitment, but was not related to withdrawal behaviors such as truancy, absenteeism, and turnover intentions.     

A Contextual Model of Control Beliefs,Behavior, and Health: Latino and European Americans with Type 2 Diabetes

Sense of control is frequently found to be related to health. A model of control beliefs, disease-management behaviors, and health indicators was tested in a sample of 74 Latino Americans and 115 European Americans with Type 2 diabetes. Two measures of control beliefs, one diabetes-specific (diabetes self-efficacy) and one global (mastery), were examined for their effects on management behaviors (diet and exercise) and on health (Hb_A1C and general health). Results indicated that the relationship between control and management behaviors varied by measure of control and by group. For Latino participants, global mastery was related to management behaviors; whereas, self-efficacy was related to such behaviors among European Americans. The relationship between control and health did not appear to be mediated by management behaviors. This study provides support for a diversified approach to control, behavior, and health.     

Cross-Racial/Ethnic Eyewitness Identification: A Field Study1

Using a method similar to that of Brigham, Maass, Snyder, and Spaudling (1982), 86 adult convenience store clerks were asked to identify 3 confederate/customers, one Anglo-American, one black-American, and one Mexican-American who had visited their stores 2 hours earlier. Wilcoxon matched pairs signed-rank test showed that clerks were superior at identifying customers of their own racial or ethnic group, Z= 2.84, p < .002. For clerks who made an identification, the correlation between the recognition accuracy and confidence in their identification was not significant, r_pbis (56)= .05. The results of this field study paralleled those found in most laboratory experiments of cross-racial/ethnic identification and demonstrated that Mexican-Americans are subject to the own/other groups identification accuracy phenomenon as well.     

The Cognitive Architecture of Perceived Animacy: Intention,Attention, and Memory

Human vision supports social perception by efficiently detecting agents and extracting rich information about their actions, goals, and intentions. Here, we explore the cognitive architecture of perceived animacy by constructing Bayesian models that integrate domain‐specific hypotheses of social agency with domain‐general cognitive constraints on sensory, memory, and attentional processing. Our model posits that perceived animacy combines a bottom–up, feature‐based, parallel search for goal‐directed movements with a top–down selection process for intent inference. The interaction of these architecturally distinct processes makes perceived animacy fast, flexible, and yet cognitively efficient. In the context of chasing, in which a predator (the “wolf”) pursues a prey (the “sheep”), our model addresses the computational challenge of identifying target agents among varying numbers of distractor objects, despite a quadratic increase in the number of possible interactions as more objects appear in a scene. By comparing modeling results with human psychophysics in several studies, we show that the effectiveness and efficiency of human perceived animacy can be explained by a Bayesian ideal observer model with realistic cognitive constraints. These results provide an understanding of perceived animacy at the algorithmic level—how it is achieved by cognitive mechanisms such as attention and working memory, and how it can be integrated with higher‐level reasoning about social agency.     

Repetition and Reconfiguration: Demand‐Based Confabulation in Initial Eyewitness Memory

Repeated recall, as a result of repeated questioning, is typical of situations involving eyewitness evidence. The present study addressed questions of eyewitness performance with reference to repeated questioning in an initial interview, in a format based on actual police procedures. This experiment focused on eyewitness accuracy, eyewitness confidence, and the addition of false details to eyewitness accounts. Ninety‐two adult respondents were asked to recall all the information they could from a single viewing of a scene depicting an assailant aiming a handgun at a victim. This initial question was followed by three additional questions, in which respondents were asked to report any additional details they could recall. On average, respondents provided several times as many correct as false details to the initial question. However, performance deteriorated significantly to the three subsequent questions; on average, across the three subsequent questions, witnesses recalled nearly as much false as accurate information. Witness confidence was positively related to amount of accurate information recalled. However, confidence was also positively related to the number of instances of erroneous recall. These results indicate that reconfigurative dynamics begin to operate, producing confabulated responses in response to questioning demands, as early as the initial interview. This work may also help to clarify the critical relationship between accuracy and confidence in eyewitness reportage, at least within the framework reflected by the present research.

A Four-Factor Model of Perceived Control: Avoiding, Coping, Obtaining, and Savoring

ABSTRACT This study provides evidence that people evaluate their control over events and over feelings separately with respect to both positive and negative experiences Confirmatory factor analyses revealed that subjects made separate self-evaluations of control regarding their ability to (a) avoid negative outcomes, (b) cope with negative outcomes, (c) obtain positive outcomes, and (d) savor positive outcomes In addition, beliefs about avoiding and obtaining were more highly correlated (r = 50) than were beliefs about coping and savoring (r= 27) It is argued that coping and savoring involve different sets of cognitive and behavioral skills Multiple regression analyses generally indicated that beliefs about avoiding and coping related more strongly to measures of subjective distress, whereas beliefs about obtaining and strongly related more strongly to measures of subjective well-being These four control beliefs are discussed in relation to other conceptual models of control, and ways in which savoring may promote perceived control are described     

Overcoming Misinformation Effects in Eyewitness Memory: Effects of Encoding Time and Event Cues

Eyewitness memory is often distorted when misleading information is presented to subjects after encoding. Three experiments explored ways to overcome these misinformation effects. In Experiment 1, subjects viewed slides of a robbery, at a rate of four or seven seconds per slide. Five minutes later subjects were given a recognition test with few (1–3) or numerous (6–13) event cues. Providing numerous retrieval cues improved overall performance, but did not reduce the effects of misinformation. W ith week-long delays (Experiment 2) numerous retrieval cues did eliminate misinformation effects, but only when subjects viewed slides at the slower rate (seven seconds per slide). Experiment 3 essentially replicated this pattern, using a modified test to eliminate any biasing effects of distractors. Given adequate encoding and numerous retrieval cues, misinformation effects were eliminated, suggesting that under some conditions misinformation makes event memory inaccessible, but not unavailable.     

The Effects of Recent Sleep Duration,Sleep Quality,and Current Sleepiness on Eyewitness Memory

This study examined whether three sleep‐related variables (current sleepiness, the duration of the previous night's sleep and the quality of that sleep) were predictors of an eyewitness's ability to remember central and peripheral details from a crime. Participants first completed a self‐report questionnaire assessing their current sleepiness, then watched a video of a bank robbery, next completed a self‐report questionnaire about their previous night's sleep, and then had their memory of the crime tested. It was found that as the eyewitnesses' sleep quality decreased and their sleepiness increased, their ability to accurately recollect peripheral details from the crime was compromised. This is the first demonstration that variations in sleep prior to witnessing a crime, and sleepiness at the time of a crime, can predict eyewitness memory.

Predicting Perceived Risk of Crime: a Multilevel Study

With a sample of Italians selected from 71 Italian counties (N = 1,868), we performed two multilevel analyses aimed at predicting the perceived risk of crime at local (i.e., in the participants' county of residence) and at societal (i.e., in the context of Italian society) levels. A significant proportion of the variation in local risk perception was at the county level. The following individual variables predicted higher levels of this variable: indirect victimization, the perception of social and physical disorder, being a woman, being poorly educated, and being an older person. Among the ecological predictors, the crime rate and unemployment rate predicted higher levels of local crime risk perception, while the immigrant rate did not. Perceived risk of crime at the societal level did not show significant variation at the county level. Education, being a man, trusting people, and adhesion to post‐materialistic values predicted lower levels of societal crime risk perception, while number of sons/daughters and exposure to television news increased it. The limitations and possible development of this study are discussed.
