A prospective study was conducted to investigate whether enhancing attributional style and positive life events are associated with recovery from depression through the mediation of increased hopefulness, as predicted by the Needles and Abramson (1990) model of recovery from depression. The Attributional Style Questionnaire, Beck Depression Inventory, Beck Hopelessness Scale, Dysfunctional Attitudes Scale, Uplifts Scale, and Revised Hassles Scale were administered to 32 depressed psychiatric inpatients shortly after admission and readministered a mean of 10 days later. The results indicated that the combined effects of enhancing attributional style and positive life events predicted decreases in hopelessness, which were in turn associated with decreases in depression symptom levels. By contrast, neither the combined effects of depressotypic attributional style and life events nor the combined effects of dysfunctional attitudes and life events was associated with decreases in hopelessness or depression symptom levels.  相似文献

Male and female students participated in an experiment designed to test specific hypotheses fromsexual strategies theory (Buss & Schmitt, 1993) regarding their preferences for certain personal and physical traits in a potential mate. Participants distributed 50 points among a number of trait-pairs. The items consisted of a consensually valued trait-pair, “biologically relevant” trait-pairs, and a reference to ethnic and cultural similarity. In Condition 1 participants distributed the points among the trait-pairs without any additional information about the potential mate; Condition 2 participants distributed the points after being asked to assume the potential mate possessed some biologically relevant traits. Males, compared to females, assigned more points to trait-pairs signalling highreproductive value, and females, compared to males, assigned more points to trait-pairs signalling highresource potential. Male and female participants in Condition 2, compared to control participants, distributed more points among the opposite genders’ preferred traits. Discussion focused on speculation that assuming a potential mate possessed biologically relevant traits increases the desirability of other traits related to the solution of common and genderspecific long-term mating problems.  相似文献

Pairwise preference data are represented as a monotone integral transformation of difference on the underlying stimulus-object or utility scale. The class of monotone transformations considered is that in which the kernel of the integral is a linear combination of B-splines. Two types of data are analyzed: binary and continuous. The parameters of the transformation and the underlying scale values or utilities are estimated by maximum likelihood with inequality constraints on the transformation parameters. Various hypothesis tests and interval estimates are developed. Examples of artificial and real data are presented.This investigation was supported in part by a research grant from the Natural Sciences and Engineering Research Council Canada.  相似文献

The applicability of Tajfel's social identity theory of intergroup relations was tested within a field situation of nursing, where high and low status trainee nursing groups are undergoing social change in status relations through a merger. The status relations of the two groups were assessed by examining advantages, disadvantages and subjective characteristics attributed to the groups. Close contact between groups may account for the unexpected reduction in intergroup differentiation when explict comparisons were made. No greater illegitimacy in perceived status relations was reported by the low status group, although more dissatisfactions were evidenced in terms of attributed disadvantages, a less positive ingroup identification, and a high proportion of the low status group who want change either through movement into the superior group, or by dissolving status relations through the merging of the two groups. Attempts to merge are geared towards increasing similarity between groups by gaining recognition for those high status characteristics the group believes it has acquired. With a view to social change, the non-mobile low status subgroup are evolving a new and positive social identity for the group, perceiving little difference between groups. Strong intergroup differentiation by the high status group reflects the perceived threat of social change to the high status group.  相似文献

In Experiment 1, complete presentation of the study list produced better free recall learning than did the usual item-by-item (discrete) presentation. The difference was large and held for items occurring one, two, or three times within a list, whether items were spaced or massed, and for discrete presentation rates of 2, 4, and 6 sec/item. Experiment 2 replicated this superiority of complete over discrete presentation (equating total study time), and Experiment 3 extended the finding to paired associate learning. Experiments 2 and 3 indicated that multiple presentations of a list at fast rates were superior to a single presentation at a more standard rate and only slightly inferior to a single, complete presentation. Practical implications for instruction were pointed out, as were problems that certain of the results pose for theories that emphasize strategic (or at least extended) processing of items for encoding.  相似文献

To secure information on which aspects of linguistic functioning might be mediated by the nondominant hemisphere, a test battery assessing sensitivity to narrational and humorous materials was administered to a population of right-hemisphere-damaged patients, as well as relevant control groups of normal, aging, and aphasic individuals. While elementary linguistic functioning was adequate, the right-hemisphere-injured groups exhibited consistent difficulties in respecting the boundaries of a fictive entity, assessing the plausibility of elements within a story or joke, selecting the appropriate punch line for a joke, and integrating elements of a story into a coherent narrative. Certain elements—specifically emotional content and noncanonical facts injected into a narrative—also posed characteristic difficulties for these patients. The results suggest that, in contrast to the other populations, right-hemisphere patients exhibit special difficulties in processing complex linguistic entities and in utilizing the surrounding context as they assess linguistic messages.  相似文献

The initiation of the spontaneous gestures of Wernicke's aphasics was analyzed in relation to shifts in semantic content between the syntactic boundaries of main clauses and embedded clauses. Gestures proved more likely to arise at the initial boundaries of embedded clauses when these were semantically discontinuous with the main clause than when these were semantically related to the main clause. Spontaneous gestures may signal underlying shifts in semantic intention, thereby reflecting the difficulties encountered by Wernicke's aphasics in maintaining a coherent stream of thought across syntactic boundaries.  相似文献

Reasons for unsafe sex were examined using an illusions of control framework. Heterosexual college students (N= 301) and gay men (N= 248) were surveyed regarding perceived control over exposure to HIV, of vulnerability to HIV, use of illusory control in chance situations, and real and illusory strategies for protection against HIV. As predicted, the use of illusory control in chance situations was associated with more illusory HIV protection in both samples. Illusory protection strategies were associated with feeling less vulnerable to HIV which was mediated by perceptions of control over exposure to HIV. Suggestions for intervention include providing information about the illusory nature of some protective strategies and a focus on failing to protect oneself from STDs.  相似文献

These experiments were motivated by the idea that many types of nondeclarative memory are by-products arising from the plasticity that is inherent in much of the nervous system. We hypothesized that two types of repetition priming, word-stem completion (WSC) priming and perceptual identification (PI) priming, rely on different mechanisms because the WSC task and the PI task engage different cognitive and brain processes. We tested this hypothesis by manipulating word familiarity. The results, impaired WSC priming but intact PI priming with unfamiliar words, indicate that WSC priming relies primarily on a modification mechanism, whereas PI priming relies primarily on an acquisition mechanism. Our conclusions are consistent with component processes theories of nondeclarative memory.  相似文献
