Normal performance on the Tower of Hanoi puzzle by amnesic patients has been taken as support for viewing this problem solving task as having a nondeclarative memory component. Individuals in each decade of life between the 20s and 80s were asked to solve this puzzle four times in four sessions with intersession intervals from 1 to 7 days (Davis & Keller, 1998). Participants in their 70s and 80s were significantly impaired compared to participants in their 20s and 30s. The elderly were also significantly impaired on five immediate trials of a 15 words verbal recall test. Participants were readministered these tests an average of 6.6 years later for the elderly (n = 12) and 7.7 years later for the young (n = 11). For the Tower of Hanoi, the performance of the elderly, but not the young individuals, was significantly poorer than their original performance. For the verbal recall test, no significant change over time was detected for the young or elderly participants. These findings support the view that some nondeclarative and/or problem solving tasks demonstrate as great or greater decline with age than some declarative tasks. 相似文献

Revisiting Group Attachment: Ethnic and National Identity 总被引:1,自引:0,他引:1
Thomas C. Davis 《Political psychology》1999,20(1):25-47
The study of ethnic and national identity, owing to the complex interaction between individuals, groups, and systems, has not remained confined to traditional disciplinary boundaries. In particular, a branch of social-psychological research has provided insight into the most fundamental aspect of this phenomenon, subjective bonds between individuals and groups. Here, data derived from a Q-methodological study of Basque national identity are used to show that claims advanced within the existing literature appear to be restricted in their ability to explain subjective attachment to the nation; that is, they cannot adequately account for the types of bonds that emerged from the Basque case study. Primarily through Q methodology, an alternative explanation and method for uncovering the ties between individuals and groups is offered. In the place of previously vague and restrictive a priori categories of collective attachment, Q is shown to offer a means by which to explore the subjective nature of ethnic and national identification. 相似文献

A live showup (known as a street identification in the UK) allows the perpetrator to be identified shortly after a street crime. If the suspect disputes the identification, a video line‐up often ensues. Four experiments examined the reliability of live showups and their influence on a subsequent video line‐up using realistic procedures and conditions. Similar proportions of culprits and innocent suspects were identified from live showups and video line‐ups. Both culprits and innocent suspects previously identified were likely to be identified again in a subsequent line‐up, with delays from a few minutes to a month. Only a weak effect of clothing bias was observed. There was strong evidence of commitment to a previous identification but no reliable evidence of source monitoring errors. The results suggest that a live showup is not less fair than a line‐up, but the use of repeated identification procedures introduces an unfair bias against innocent suspects.

Four studies tested the prediction that positive affect (PA) would relate more strongly to meaning in life (MIL) as a function of perceived time limitations. In Study 1 (N = 360), adults completed measures of PA and MIL. As predicted, PA related more strongly to MIL for older, compared to younger, participants. In Studies 2 and 3, adults (N = 514) indicated their current position in their life span, and rated their MIL. PA, whether naturally occurring (Study 2) or induced (Study 3), was a stronger predictor of MIL for individuals who perceived themselves as having a limited amount of time left to live. Finally, in Study 4 (N = 98) students completed a measure of PA, MIL, and future time perspective (FTP). Results showed that PA was more strongly linked to MIL for those who believed they had fewer opportunities left to pursue their goals. Overall, these findings suggest that the experience of PA becomes increasingly associated with the experience of MIL as the perception of future time becomes limited. The contribution of age related processes to judgments of well-being are discussed. 相似文献

Face perception skills are fundamental to social cognition, yet they vary markedly across individuals. This diversity has stimulated controversy over the relative contributions of genetic factors, prenatal environment, and postnatal experience to face perception. Recent twin studies have found that face perception is heritable, highlighting the potential for substantial prenatal determination of these skills. In contrast, previous work on potential influences of the prenatal hormonal environment on social cognition have found no association between 2D:4D, a marker for prenatal androgen exposure, and processing of facial emotional expressions, apparently precluding a major role for prenatal hormones in governing face perception. We propose that substantial predictive relationships between 2D:4D and face perception may have been masked in previous work because the task employed required both face perception and processing of others?? emotions, the latter component being greatly influenced by circulating hormones in adults. To assess prenatal hormone influences on face perception without requiring emotion processing, we related 2D:4D to the face inversion effect (FIE), a measure of the recruitment of specialist face processes to visual perception. The magnitude of the resulting predictive relationship (r = .52) compared surprisingly well with that found between identical twins?? face perception (rs = .27?C.61), suggesting that mechanisms of 2D:4D may account for a substantial proportion of perinatal influences on face processing. Furthermore, we employed 2D:4D as a common scale to map individual differences in the FIE onto prenatal testosterone:estrogen ratios, assayed by Lutchmaya, Baron-Cohen, Raggatt, Knickmeyer, and Manning (Early Human Development 77:23?C28, 2004). The substantial overlap between the two data sets further implicates prenatal steroids in adult face perception skills. 相似文献

Objective: To examine components of family-centered care in families' stories about treatment decision making for their child with ADHD. Method: Twenty-eight families participated in qualitative interviews that addressed families' perspectives on (a) the treatment decision-making process, (b) the cause and impact of their child's symptoms, and (c) treatment goals and preferences. Results: The majority of families preferred to be primary or shared decision makers regarding treatment decisions. Families' perspectives on the cause of the child's symptoms varied and often were not consistent with a biomedical framework. Families described multiple areas of impairment on child, family relationships, and family functioning. Perspectives toward evidence-based treatments were mixed, with families also expressing interest in and pursuing interventions not delineated in current treatment guidelines. Conclusion: These findings reinforce the importance of eliciting families' perspectives and involving these important stakeholders in shared decision making as critical components of family-centered care for children with ADHD. 相似文献

ABSTRACT The present study aimed to investigate changes in facial expression recognition across the lifespan, as well as to determine the influence of fluid intelligence, processing speed, and memory on this ability. Peak performance in the ability to identify facial affect was found to occur in middle-age, with the children and older adults performing the poorest. Specifically, older adults were impaired in their ability to identify fear, sadness, and happiness, but had preserved recognition of anger, disgust, and surprise. Analyses investigating the influence of cognition on emotion recognition demonstrated that cognitive abilities contribute to performance, especially for participants over age 45. However, the cognitive functions did not fully account for the older adults' impairments on expression recognition. Overall, the age-related deficits in facial expression recognition have implications for older adults' use of non-verbal communicative information. 相似文献

Changes to our everyday activities mean that adult language users need to learn new meanings for previously unambiguous words. For example, we need to learn that a "tweet" is not only the sound a bird makes, but also a short message on a social networking site. In these experiments, adult participants learned new fictional meanings for words with a single dominant meaning (e.g., "ant") by reading paragraphs that described these novel meanings. Explicit recall of these meanings was significantly better when there was a strong semantic relationship between the novel meaning and the existing meaning. This relatedness effect emerged after relatively brief exposure to the meanings (Experiment 1), but it persisted when training was extended across 7?days (Experiment 2) and when semantically demanding tasks were used during this extended training (Experiment 3). A lexical decision task was used to assess the impact of learning on online recognition. In Experiment 3, participants responded more quickly to words whose new meaning was semantically related than to those with an unrelated meaning. This result is consistent with earlier studies showing an effect of meaning relatedness on lexical decision, and it indicates that these newly acquired meanings become integrated with participants' preexisting knowledge about the meanings of words. 相似文献
