Collaborative problem solving occurs in situations in which two or more individuals cooperate in appraising, representing,
and solving a variety of cognitive tasks. Collaborative groups are the context for much everyday cognitive activity in adulthood.
Collaboration has been explored as a means through which older adults may maintain high levels of performance, perhaps compensating
for individual-level cognitive and neurological decline. This study explored the effects of collaboration (group size) and
adult age on solving both fixed- and unrestricted-alternatives 20 Questions tasks. Younger (M=24.3 years) and older (M=67.9 years) adults were randomly assigned to one of three homogeneous group size conditions: individuals, dyads, and tetrads.
Results indicated some dissociation between individual-level performance (poorer for older adults) and collaborative performance
(better for older adults). For the fixed-alternatives task, older adults produced more of the relatively inefficient hypothesis-scanning
questions than did younger adults. In contrast, older collaborative groups produced more of the efficient constraint-seeking
questions than hhpothesis-scanning questions, and an amount equivalent to that of younger adults. Overall performance for
the difficult unrestricted-alternatives task was less efficient for both younger and older adults. The roles of task type,
group characteristics, and adult age are discussed. 相似文献

In a concurrent validity study, a comprehensive job analysis of a mid-level secretarial position resulted in the development of highly valid employment selection instruments. Six hundred fifty-nine supervisors and 883 incumbents in 20 locations participated in the job analysis. Scores from the selection test correlated with composite ratings from a research performance appraisal (RPA) .41 (p<.001). Two forms of the test (A and B) were developed. Form A and Form B test scores and RPA composite ratings correlated .55 and .48 (p<.001) respectively. The unbiased estimate of equivalence reliability of Form A and Form B was .94. The two tests correlated .89 (p<.001). 相似文献

Students with moderate and severe disabilities often have language deficits that make the acquisition of reading challenging. Sight word instruction of daily living skills is one method of intervention that benefits students with severe disabilities who have not achieved literacy. When students with developmental disabilities are also linguistically diverse, acquisition of reading skills becomes more complex. Sight words must be chosen that are relevant to the students own community. A critical decision in planning sight word instruction is whether to provide instruction in the student's primary language or in English. These issues are discussed and an illustration is given of the heterogeneity among students with developmental disabilities who are linguistically diverse. 相似文献

A prevalent theory regarding the deterioration of semantic memory in Alzheimer's disease is that it is a bottom-up process. If this is true, performance on tests of attribute knowledge should decline more rapidly than performance on tests of categorical knowledge as dementia severity increases. In the present study, a convincing pattern of findings to either support or reject the theory failed to emerge. This raised questions regarding the ability to separate attribute and categorical knowledge, and whether one can be tested without influence of the other. Questions also were raised regarding the additional cognitive processes needed to complete tasks of semantic memory. 相似文献

Mood disorders and suicide in youth represent major health concerns requiring effective intervention strategies. This paper briefly summarizes the literature on childhood mood disorders and discusses expressed emotion (EE) and the link between lowering EE and improved outcome for mood disordered individuals. Family psychoeducation is discussed as a means of reducing EE and similarities and differences between psychoeducation and other therapeutic interventions explored. The authors' adaptations that made psychoeducation developmentally appropriate for families of children and adolescents are reviewed. Psychoeducation for families of mood disordered youth is suggested as worthy of further clinical and empirical effort. 相似文献

The Pupil Evaluation Inventory was developed to assess peer ratings of the behavior of male and female children in grades one through nine. Three homogeneous and stable factors emerged from a factor analysis: Aggression, Withdrawal and Likeability. High interrater agreement between male and female raters, stability of factorial structure, high internal consistency, and moderate concurrent validity were found across sex and grade levels. Test-retest reliability was high for a separate sample of third and sixth graders. There was a tendency for higher internal consistency and teacher-peer correlations for the Aggression factor.This research was supported by grant MH 21145 from the National Institute of Mental Health and by funds from the D.

The short-term recall of word-triads was tested, comparing retention over three types of intervals within 24 preschoolers. Retention was significantly lower in the 16 sec unfilled interval condition than in the immediate test condition. This result, predicted from preschoolers' rehearsal deficiency, differs from those obtained in previous adult and child studies. A filled interval condition, requiring irrelevant verbal activity during the 16 sec period, significantly reduced recall from that of the unfilled interval condition. Recognition of the word items on a subsequent recognition test was greater than chance and was not affected by interval condition. This suggests that the condition effects in short-term recall did not disrupt the long-term storage of the items. 相似文献

The slow or total lack of decrease in some autonomic responses during extinction in aversive conditioning and concomitant verbalizations of fear have remained a problem for learning theories and psychophysiology. Removal of the aversive stimulus should result in a rapid decrement in responding, as it does in cognitive and somatic systems. In laboratory analogues of phobia and clinical neurosis, however, such decreases do not occur in some autonomic responses and reported fear. In this article three areas of research are presented in which dissociations occur between cognitive and autonomie responses: 1) relational learning, 2) phobia, and 3) incubation. The data indicate that there are some important distinctions to be made concerning the properties of different psychological and physiological systems. These distinctions pertain to the differences between cognitive and noncognitive systems, between the two branches of the ANS, and between acquisition and extinction processes. These distinctions lead to a number of hypotheses concerning dissociations between response systems and have important implications for the understanding and treatment of neurosis. 相似文献
