Evidence suggests that research participants often fail to recall much of the information provided during the informed consent process. This study was conducted to determine the proportion of consent information recalled by drug court participants following a structured informed consent procedure and the neuropsychological factors that were related to recall. Eighty-five participants completed a standard informed consent procedure to participate in an ongoing research study, followed by a 17-item consent quiz and a brief neuropsychological battery 2 weeks later. Participants performed within the normal range on most of the neuropsychological measures, although roughly one third showed deficits on measures of executive functioning. Participants failed to recall over 65% of the consent information within 2 weeks of entering the study, and their recall was significantly correlated with verbal IQ, drug problem severity, reading ability, memory, and attention. These factors may be useful in determining whether research participants require enhanced consent procedures. 相似文献

The Lessons of the Development of the First APA Ethics Code: Blending Science,Practice, and Politics
The Ethics Code of the American Psychological Association (APA) is a bedrock of the profession. The contextual factors of society affect the Ethics Code of the APA, resulting in an ever-changing document. The context of the reorganization of the APA after World War II created an initial impetus toward a formalized code. A key contextual feature of the Code's development was the use of the Critical Incident Technique, which was based in the empirical aspirations of the psychological field. This article explores the historical context around the APA's decision to draft an ethics code, reviews its development, and discusses its role for psychologists today. 相似文献

Although temporal dynamics are inherent aspects of diagnostic tasks, few studies have investigated how various aspects of time course influence hypothesis generation. An experiment is reported that demonstrates that working memory dynamics operating during serial data acquisition bias hypothesis generation. The presentation rate (and order) of a sequence of serially presented symptoms was manipulated to be either fast (180 ms per symptom) or slow (1,500 ms per symptom) in a simulated medical diagnosis task. When the presentation rate was slow, participants chose the disease hypothesis consistent with the symptoms appearing later in the sequence. When the presentation rate was fast, however, participants chose the disease hypothesis consistent with the symptoms appearing earlier in the sequence, therefore representing a novel primacy effect. We predicted and account for this effect through competitive working memory dynamics governing information acquisition and the contribution of maintained information to the retrieval of hypotheses from long-term memory. 相似文献

This study examined the extent to which individual, peer, and family factors predicted the onset of community violence exposure in middle and high school, as well as the indirect effects of early factors. We were particularly interested in the timing of exposure to community violence during adolescence, and thus conducted survival analyses on data from 632 urban youth, followed from first grade through high school. Early aggressive behavior and poor academic readiness were associated with an earlier onset of community violence exposure in adolescence. The effects of early aggression on community violence exposure and victimization were accounted for, in part, by peer rejection and deviant peer affiliation; there was no evidence of moderation by gender or parental monitoring. Findings highlight potential targets for preventive interventions with youth at risk of community violence exposure. 相似文献

This paper seeks to bring together two previously separate research traditions: research on spatial orienting within the visual cueing paradigm and research into social cognition, addressing our tendency to attend in the direction that another person looks. Cueing methodologies from mainstream attention research were adapted to test the automaticity of orienting in the direction of seen gaze. Three studies manipulated the direction of gaze in a computerized face, which appeared centrally in a frontal view during a peripheral letter-discrimination task. Experiments 1 and 2 found faster discrimination of peripheral target letters on the side the computerized face gazed towards, even though the seen gaze did not predict target side, and despite participants being asked to ignore the face. This suggests reflexive covert and/or overt orienting in the direction of seen gaze, arising even when the observer has no motivation to orient in this way. Experiment 3 found faster letter discrimination on the side the computerized face gazed towards even when participants knew that target letters were four times as likely on the opposite side. This suggests that orienting can arise in the direction of seen gaze even when counter to intentions. The experiments illustrate that methods from mainstream attention research can be usefully applied to social cognition, and that studies of spatial attention may profit from considering its social function. 相似文献

ABSTRACTStatistical learning refers to the extraction of probabilistic relationships between stimuli and is increasingly used as a method to understand learning processes. However, numerous cognitive processes are sensitive to the statistical relationships between stimuli and any one measure of learning may conflate these processes; to date little research has focused on differentiating these processes. To understand how multiple processes underlie statistical learning, here we compared, within the same study, operational measures of learning from different tasks that may be differentially sensitive to these processes. In Experiment 1, participants were visually exposed to temporal regularities embedded in a stream of shapes. Their task was to periodically detect whether a shape, whose contrast was staircased to a threshold level, was present or absent. Afterwards, they completed a search task, where statistically predictable shapes were found more quickly. We used the search task to label shape pairs as “learned” or “non-learned”, and then used these labels to analyse the detection task. We found a dissociation between learning on the search task and the detection task where only non-learned pairs showed learning effects in the detection task. This finding was replicated in further experiments with recognition memory (Experiment 2) and associative learning tasks (Experiment 3). Taken together, these findings are consistent with the view that statistical learning may comprise a family of processes that can produce dissociable effects on different aspects of behaviour. 相似文献

ABSTRACT Recent work in social cognitive aging has suggested that older adults are more likely than younger adults to activate and use stereotypic information, even when they intend not to. Furthermore, evidence suggests that older adults have difficulty altering their interpretation of a situation, even when it has become clear that their initial interpretation is incorrect. In the current study, younger and older adults read a series of narratives in which a character had a sex-stereotyped occupation (e.g., a plumber is stereotypically male), and the character's gender was either consistent or inconsistent with that stereotype. Explicit labeling of gender was also varied. Results revealed that with explicit labeling, older adults were able to discount their stereotypes and avoid processing difficulties when subsequent stereotype-inconsistent information was encountered. These data suggest that when counter-stereotypic information is explicitly provided at encoding, older adults are no more likely than younger adults to rely on stereotypes, and are similarly capable of altering their interpretation of a situation when information suggests that interpretation is incorrect. These findings indicate that although older adults are more prone to the influence of unwanted stereotypes, this effect can be averted and judgments can be made more egalitarian by providing older adults with explicit stereotype contradiction at encoding. 相似文献

ABSTRACT Previous studies demonstrating age-related impairments in recognition memory for faces are suggestive of underlying differences in face processing. To study these differences, we monitored eye movements while younger and older adults viewed younger and older faces. Compared to the younger group, older adults showed increased sampling of facial features, and more transitions. However, their scanning behavior was most similar to the younger group when looking at older faces. Moreover, while older adults exhibited worse recognition memory than younger adults overall, their memory was more accurate for older faces. These findings suggest that age-related differences in recognition memory for faces may be related to changes in scanning behavior, and that older adults may use social group status as a compensatory processing strategy. 相似文献
