Seventy-two normal adult male subjects wrote TAT stories under baseline and either placebo- or marijuana-ingestion conditions. Marijuana subjects received 20 mg. doses of delta-9 tetrahydrocannabinol. The stories were keypunched and content analyzed with the Regressive Imagery Dictionary, which yields a score for primary process content. Results indicate that marijuana, relative to placebo, caused subjects to write stories with a higher proportion of primary process content than they had included in baseline stories.  相似文献

Despite significant advances over the past three decades in our understanding of the implicit dangers in ad hoc psychometric procedures, some important questions remain, particularly as regards the nature of the underlying reasoning process by which subjectively meaningful theoretical impressions are formulated and expressed. The present article seeks to address this issue, with particular attention being given to the distinction between demonstrative and dialectical reasoning. Evidence is offered to show that, at least under certain conditions, intuitive psychometricians formulate and express theoretical impressions on the basis of a reasoning process that is essentially dialectical in nature. Some major implications of this point of view for the study of personality theory are discussed. The limitations of the evidence presented, and the need for further research, are forgone.  相似文献

Two studies were conducted to determined the effects of specific learning centers on preschoolers' functional uses of language. In Study 1, preschoolers in three separate same-age classrooms (2-, 3-, and 5-year-olds) were observed on a time sampling scheduling during their free play periods for four weeks. Preschoolers' individual utterances were coded as serving one or more than one function; functions were defined following Halliday. The housekeeping and block centers tended to elicit the most individual and multifunctional utterances. The fantasy play and social interaction among children in these centers were thought to be responsible for this mature use of language.In Study 2, same-age and same-sex dyads from two age groups (4- and 5-year-olds) were observed in experimental settings playing with blocks alone and with dramatic props alone. Both contexts elicited a predominance of imaginative language, though the dramatic context elicited more imaginative language than the blocks. With age, children generated more individual functions and multifunctional utterances.  相似文献

Private secondary school students differing in achievement motivation took part in a learned helplessness experiment using a triadic design and noncontingent rewards. A clear learned helplessness effect was observed in both high and low achievement motivation groups. The findings confirmed those from an earlier study using younger subjects drawn from a lower socioeconomic background. However, the results of both experiments were quite different from those of another recently reported investigation using university students that found facilitation as well as an interaction between achievement motivation level and treatment (Jardine & Winefield, 1981). It is concluded that the development of learned helplessness probably depends on the kind of environment in which noncontingent outcomes are experienced.  相似文献

The present research was designed to test the hypothesis that perceptions of consensus about the collective experience of psychological problems, as well as the distinctive presence of a community disaster, would affect attributions of externality about such problems. Specifically, it was hypothesized that (1) higher levels of consensus would be associated with greater external attributions of causality, (2) attributions would be more external if the problem began after the disaster (high distinctiveness) than before the disaster, and (3) the occurrence of the disaster would magnify the positive relationship between high consensus and external causality attributions, because of the presence of a distinctive and salient external event. These hypotheses were tested with victims of a flash flood. Results supported the interaction prediction (Hypothesis 3) for the problem of depression, but not for anxiety. In addition, for depression and anxiety, greater consensus was indirectly associated with greater externality, regardless of distinctiveness (Hypothesis 1). However, for somatization, none of the hypotheses were supported. The results are discussed in terms of the applied implications for postdisaster intervention programs to reduce psychopathology.  相似文献

Analysis of the elements of attention: A neuropsychological approach   总被引:15,自引:0,他引:15  
A model for conceptualizing the components or elements of attention is presented. The model substitutes for the diffuse and global concept of attention a group of four processes and links them to a putative system of cerebral structures. Data in support of the model are presented; they are derived from neuropsychological test scores obtained from two samples, the first consisting of 203 adult neuropsychiatric patients and normal control subjects, and the second, an epidemiologically-based sample of 435 elementary school children. Principal components analyses of test scores from these two populations yielded similar results: a set of independent elements of attention that are assayed by different tests. This work presents a heuristic for clinical research in which the measurement of attention is essential.  相似文献
