Sustained attention deficits represent one of the most robust findings in the study of schizophrenia and schizotypy. However, very little is known about the nature of sustained attention performance and schizotypy in the general adult population. The present study assessed sustained attention performance in a large, normative adult community sample (N = 305) with no history of psychosis using the Continuous Performance Test-identical pairs version (CPT-IP). Associations between overall CPT-IP performance and schizotypal personality disorder features, controlling for the effects of age, sex, and educational level, revealed diminished sensitivity (d', discriminability), and increased random errors were related to increased reality distortion features. These data, drawn from a general population sample, provided support for overall sustained attention deficits as an endophenotype for schizophrenia liability. 相似文献

Are children who experience an event repeatedly more suggestible about an instance of the event than children who experience it once? Researchers have answered this question both in the affirmative and in the negative. In this study, we hypothesized that the degree of association between details that changed across instantiations of the event would help to explain the discrepancy. Preschoolers (4- and 5-year-olds) and first graders (6- and 7-year-olds) participated in either a single play session or four repeated play sessions, each of which contained 16 critical details. Across play sessions in the repeat-event condition, half of the critical details were associated and half were not associated. During a biasing interview 2 weeks later, children were misinformed about half of the critical details. The next day, children answered free and cued recall questions about the target play session. Among older children, repeat-event participants were more suggestible than single-event participants, especially for high-association details. Among younger children, repeat-event participants were more suggestible than single-event participants for low-association details. Consistent with some current theories of children's memory, older children were more suggestible than younger children. 相似文献

D. DeSteno, M. Y. Bartlett, J. Braverman, and P. Salovey proposed that if sex-differentiated responses to infidelity are evolved, then they should be automatic, and therefore cognitive load should not attenuate them. DeSteno et al. found smaller sex differences in response to sexual versus emotional infidelity among participants under cognitive load, an effect interpreted as evidence against the evolutionary hypothesis. This logic is faulty. Cognitive load probably affects mechanisms involved in simulating infidelity experiences, thus seriously challenging the usefulness of cognitive load manipulations in testing hypotheses involving simulation. The method also entails the assumption that evolved jealousy mechanisms are necessarily automatic, an assumption not supported by theory or evidence. Regardless of how the jealousy debate is eventually settled, cognitive load manipulations cannot rule out the operation of evolved mechanisms. 相似文献

Much research emphasizes heuristic use of stereotypes, though stereotypes have long been considered as capable of influencing more thoughtful processing of social information. Direct comparisons between thoughtful and non-thoughtful stereotyping are lacking in the literature. Recent research in attitude change emphasizes the different consequences of judgments arising from relatively thoughtful versus non-thoughtful processes. Therefore, increased thought could not only fail to decrease stereotyping but might also create stereotypic perceptions that are more likely to have lasting impact. The current studies demonstrate thoughtful and non-thoughtful stereotyping within the same setting. More thoughtful stereotyping is more resistant to future attempts at change and to warnings of possible bias. Implications are discussed for the typical research questions asked after observing stereotypic judgements. 相似文献

The authors theorize that individuals with high self-esteem functionally integrate positive and negative partner information in memory, whereas those low in self-esteem segregate such information. The authors obtained support for this view in 7 studies. In a first set, participants judged whether positive and negative traits presented in an alternating or nonalternating order applied to a partner. Low but not high self-esteem individuals were slowed by the alternating order when judging relationship partners (but not inanimate objects). In a 2nd set, participants answered questions tapping integrated thinking, self-esteem, and other attributes. Higher self-esteem was associated with more integrated thinking when other attributes were controlled. In a final study, anxiously attached individuals were more labile in rating their spouse over a 5-day period. 相似文献

This study investigated whether higher seeded players have an advanage in the only match play event on the PGA Tour. Analysis showed that the higher seeded won 54% of the time (p=.06); the correlation was .17 (p<.01) between higher seeded players winning and the difference in World Rankings between players. Given professional golfers are at the highest end of the distribution of golf ability, these players are so nearly equal in ability, it is mainly a matter of chance who will win a match play event or who will have the best round on any given day. 相似文献

The paper describes the development of a cognitive therapy (CT) program for post-traumatic stress disorder (PTSD) that is based on a recent cognitive model (Behav. Res. Therapy 38 (2000) 319). In a consecutive case series, 20 PTSD patients treated with CT showed highly significant improvement in symptoms of PTSD, depression and anxiety. A subsequent randomized controlled trial compared CT (N = 14) and a 3-month waitlist condition (WL, N = 14). CT led to large reductions in PTSD symptoms, disability, depression and anxiety, whereas the waitlist group did not improve. In both studies, treatment gains were well maintained at 6-month follow-up. CT was highly acceptable, with an overall dropout rate of only 3%. The intent-to-treat effect sizes for the degree of change in PTSD symptoms from pre to post-treatment were 2.70-2.82 (self-report), and 2.07 (assessor-rated). The controlled effect sizes for CT versus WL post-treatment scores were 2.25 (self-report) and 2.18 (assessor-rated). As predicted by the cognitive model, good treatment outcome was related to greater changes in dysfunctional post-traumatic cognitions. Patient characteristics such as comorbidity, type of trauma, history of previous trauma, or time since the traumatic event did not predict treatment response, however, low educational attainment and low socioeconomic status were related to better outcome. 相似文献

Informant reports of psychiatric patient behavior are collected routinely during intake interviews and to monitor therapeutic interventions. We investigated agreement between informant and adult psychiatric patient reports of patient behaviors (N=110). Behaviors were about substance use, physical and mental health, employment, illegal behavior, and recreational and social activities. Informant agreement with patients regarding whether or not a particular behavior occurred recently and also behavior frequency ratings were moderate overall (M r=.47 for frequency) and highly variable (rs=-.09 to .80). No informant, patient, or relationship characteristics were found consistently to moderate agreement. Thus, informants can report very accurately about the presence and frequency of some, but not all, patient behaviors. Low patient-informant agreement may be due to informants having relatively less detailed knowledge of patient behavior over time or patients not reporting accurately about certain behaviors. 相似文献

The authors found an interaction between sex of participant and sex of defendant in the leniency bias toward a smiling defendant. Differences occurred for male participants when levying punishment for a smiling male defendant vs. a smiling female defendant and for a smiling male defendant vs. a nonsmiling male defendant, whereas differences did not occur for female participants. The authors found moderating effects of physical attractiveness and smiling between guilt and punishment. The only significant positive relationship between guilt and punishment occurred for the defendant whom participants rated low in physical attractiveness and who was not smiling. When guilty, the smiling and unattractive defendant received less punishment than did the smiling and attractive defendant. The authors discussed complex relationships between physical attractiveness, smiling, guilt, and punishment. 相似文献
