Four groups of patients (depressives, schizophrenics, substance dependents and abusers), a miscellaneous group of other patients, and a group of matched normals from a general population sample were compared on the scales of the Multiple Affect Adjective Check List - Revised (MAACL-R). All scales showed highly significant differentiation among the groups. An index consisting of Depression minus Positive Affect scales was particularly effective in discriminating between depressive and other groups. A discriminant function analysis showed that the depressive could be distinguished from other patient groups and normals with an accuracy of 72% correct. The normals could be distinguished from all of the patient groups with a 60% accuracy, and 87% if the substance abuser group is ignored. The discriminant validity among the nondepressive patient groups was not nearly as good. 相似文献

Regional brain metabolic activity of six male Sprague-Dawley rats was investigated with 2-[14C]deoxyglucose autoradiography. Regional brain metabolic activity was determined bilaterally for 60 brain structures, using laser densitometry. After 5 days of uninterrupted rapid eye movement sleep deprivation, increased metabolic activity was found in the lateral habenula, the caudal and middle parts of the limbic system, and in the corpus callosum. 相似文献

Competitive or cooperative behaviors of children were observed in two experiments. In Experiment 1, 7- to 9-year-old boys and girls played a board game with same- or opposite-sex partners under instructions which stressed either group or individual performance. Girls' behavior varied as a function of both instructions and partner sex. Girls playing the game with boys showed more highly competitive behavior than did girls who played the game with girls. Boys were highly competitive under all conditions. In Experiment 2, preschool children were observed in a similar game. For both sexes, children who played the game with opposite-sex partners were more competitive and obtained fewer rewards than those who interacted with same-sex partners. Thus, with development, boys show a change from selective competitiveness to a very general tendency to compete, while girls show a consistent tendency to vary their game behavior according to situational cues such as those provided by instructions or the sex of a game partner.A report of the first experiment was made at the Third Biennial Southeastern Conference of the Society for Research in Child Development, Chapel Hill, March 1974. The authors would like to thank the personnel of St. Francis Cabrini School and the Children's House Montessori School of New Orleans, Louisiana, for their cooperation in providing research participants. 相似文献

Most neural models for the pathophysiology of attention-deficit/hyperactivity disorder (ADHD) have centered on the prefrontal cortex and its interconnections with the striatum and other subcortical structures. However, research only partially supports these models, and they do not correspond with the development of the prefrontal cortex and its interrelated neurocircuitry. The neural and functional development of the prefrontal cortex more closely parallels recovery from ADHD as indicated by the developmental remission of symptomatology. The authors hypothesize that ADHD is due to noncortical dysfunction that manifests early in ontogeny, remains static throughout the lifetime, and is not associated with the remission of symptomatology. Data supporting this neurodevelopmental model of prefrontal cortex function in ADHD are reviewed. Research and treatment implications are discussed. 相似文献

Separating multiple processes in implicit social cognition: the quad model of implicit task performance 总被引:6,自引:0,他引:6

The authors argue that implicit measures of social cognition do not reflect only automatic processes but rather the joint contributions of multiple, qualitatively different processes. The quadruple process model proposed and tested in the present article quantitatively disentangles the influences of 4 distinct processes on implicit task performance: the likelihood that automatic bias is activated by a stimulus; that a correct response can be determined; that automatic bias is overcome; and that, in the absence of other information, a guessing bias drives responses. The stochastic and construct validity of the model is confirmed in 5 studies. The model is shown to provide a more nuanced and detailed understanding of the interplay of multiple processes in implicit task performance, including implicit measures of attitudes, prejudice, and stereotyping. 相似文献

The purpose of the present study was to test whether adult criminals with psychopathy diagnoses, more than those without, have histories of hyperactivity-impulsivity-attention problems (HIA) and conduct problems (CP). We compared psychopathic and nonpsychopathic violent criminal offenders on retrospective reports of conduct problems before the age of 15 and hyperactivity-impulsivity-attention problems before the age of 10. We used a sample of 186 adult men sentenced to prison in Sweden for 4 years or more for violent, nonsexual crimes. The mean age was 30.7( SD = 9.4). The results showed that a combination of childhood HIA problems and CP was typical for adult psychopathic offenders. They were four times more likely than chance to have had a combination of HIA problems and CP during childhood and only one-fifth as likely than chance to have had neither problem. Nonpsychopathic offenders, on the other hand, were five times more likely than chance to have had neither problem and only one-quarter as likely than chance to have had both problems. 相似文献

Empirical studies using the PCL-R (Hare, 2003) have shown no intelligence differences between psychopaths and nonpsychopaths. However, Cleckley (1976) argued that psychopaths often show superior intelligence. The purpose of the present study was to test the hypothesis that the correlation between intelligence and severity of criminal development is the opposite in psychopaths than in nonpsychopathic criminals using a sample of 370 men sentenced for violent (nonsexual) crimes. That pattern would provide a way of explaining the discrepancy between Cleckley's view and later empirical work. The results showed that for nonpsychopaths, higher total IQ and particularly verbal intelligence meant a later start in violent crime. For those diagnosed as psychopaths, however, this association was reversed. 相似文献

In two studies, the role of the number‐word sequence skill for arithmetic performance was investigated. In the first, children between 4 and 8 years of age were asked to count forward and backward on the number‐word sequence and to solve arithmetic problems followed by post‐solution interviews about solution procedures. The results demonstrated that the number‐word sequence skill predicted both number of problems solved and strategy to solve the problems. In Study 2 it was found that solving doubles (e.g., 2 + 2 = ?) problems served as a link between the number‐word sequence skill and the number of arithmetic problems solved. The findings suggest that counting on the number‐word sequence may be an early solution procedure and that, with increasing counting skill, the child may detect regularities in the number‐word sequence that can be used to form new and more accurate strategies for solving arithmetic problems. 相似文献

Two experiments competitively test 3 potential mechanisms (negativity inhibiting responses, feature-based accounts, and evaluative context) for the response latency advantage for recognizing happy expressions by investigating how the race of a target can moderate the strength of the effect. Both experiments indicate that target race modulates the happy face advantage, such that European American participants displayed the happy face advantage for White target faces, but displayed a response latency advantage for angry (Experiments 1 and 2) and sad (Experiment 2) Black target faces. This pattern of findings is consistent with an evaluative context mechanism and inconsistent with negativity inhibition and feature-based accounts of the happy face advantage. Thus, the race of a target face provides an evaluative context in which facial expressions are categorized. 相似文献
