This study provides new knowledge about the factor structure of the 12-item General Health Questionnaire (GHQ-12; D. Goldberg, 1972) through the application of confirmatory factor analysis to longitudinal data, thereby enabling investigation of the factor structure, its invariance across time, and the rank-order stability of the factors. Two community-based longitudinal adult samples with 1-year (n = 640) and 6-year (n = 330) follow-up times were studied. As a result, the correlated 3-factor model (i.e., Anxiety/Depression, Social Dysfunction, and Loss of Confidence) showed a better fit with both samples than the alternative models. The correlated 3-factor structure was also relatively invariant across time in both samples, indicating that the scale has good construct validity. The rank-order stabilities of the factors were low across time, which suggests that the GHQ-12 measures temporal mental state. 相似文献

The logic of the stimulus 总被引:1,自引:1,他引:0
This paper examines the contribution of stimulus processing to animal logics. In the classic functionalist S-O-R view of learning (and cognition), stimuli provide the raw material to which the organism applies its cognitive processes–its logic, which may be taxon-specific. Stimuli may contribute to the logic of the organism's response, and may do so in taxon-specific ways. Firstly, any non-trivial stimulus has an internal organization that may constrain or bias the way that the organism addresses it; since stimuli can only be defined relative to the organism's perceptual apparatus, and this apparatus is taxon-specific, such constraints or biases will often be taxon-specific. Secondly, the representation of a stimulus that the perceptual system builds, and the analysis it makes of this representation, may provide a model for the synthesis and analysis done at a more cognitive level. Such a model is plausible for evolutionary reasons: perceptual analysis was probably perfected before cognitive analysis in the evolutionary history of the vertebrates. Like stimulus-driven analysis, such perceptually modelled cognition may be taxon-specific because of the taxon-specificity of the perceptual apparatus. However, it may also be the case that different taxa are able to free themselves from the stimulus logic, and therefore apply a more abstract logic, to different extents. This thesis is defended with reference to two examples of cases where animals' cognitive logic seems to be isomorphic with perceptual logic, specifically in the case of pigeons' attention to global and local information in visual stimuli, and dogs' failure to comprehend means-end relationships in string-pulling tasks.This contribution is part of the special issue “Animal Logics” (Watanabe and Huber 2006). 相似文献

We examined participants' reading and recall of informed consent documents presented via paper or computer. Within each presentation medium, we presented the document as a continuous or paginated document to simulate common computer and paper presentation formats. Participants took slightly longer to read paginated and computer informed consent documents and recalled slightly more information from the paginated documents. We concluded that obtaining informed consent online is not substantially different than obtaining it via paper presentation. We also provide suggestions for improving informed consent--in both face-to-face and online experiments. 相似文献

This study tested the efficacy of a cognitive-behavioral psychological intervention (CBT) targeting aggressive driving behaviors within both a court-referred (N=20) and a self-referred community (N=8) sample as compared to a symptom monitoring (SM) only control condition. Treatment outcome was assessed through the use of daily driving diaries, standard psychological tests, and a global rating of change scale. The CBT treatment condition improved more than the SM condition as assessed through the daily driving diaries. Although the court-referred and self-referred samples showed equivalent improvement on the driving diaries, the self-referred group improved more on measures of general anger. Standardized measures of driving anger, state anxiety and measures of general anger indicated significant change in the expected direction. Aggressive drivers who met criteria for Intermittent Explosive Disorder (IED) showed a trend to improve less than non-IED aggressive drivers. Treatment gains were maintained at the 2-month follow-up point. 相似文献

When we read that two protagonists in a story chatted together for a couple of minutes, do we draw inferences about the topic of the conversation on the basis of information presented earlier in the text? Participants read passages in which protagonists part and later reunite; the passages ended with a sentence either that implied conversation or did not. In Experiment 1, participants' continuation sentences indicated that inferences about the topic of conversation were drawn. Recognition probe data in Experiment 2 provided more immediate evidence of such inferences. Experiment 3 addressed a possible confound in Experiment 2 and again provided evidence that readers inferred the continuation of the conversation. In Experiments 4 and 5, we investigated the effect of having the targeted conversational topic be a secret that should not be shared between the protagonists. The results are discussed in terms of the collaboration between passive, memory-based text processing and schema-driven comprehension processes. 相似文献

Research shows that negation can suppress the activation of propositions presented explicitly in text, but does negation have a similar effect on propositions that can be inferred? That is, does negation inhibit the inference process? Four experiments investigated whether a deductive inference that produces a negated conclusion (therefore not a) is made as readily as a similar inference form that yields an affirmative conclusion (therefore a). A combination of naming latencies, verification times, and reading times indicate that negation does not affect the deductive inference process itself, although it may inhibit the activation of inferred concepts. 相似文献

Femininity and fertility in sisters with twin brothers: prenatal androgenization? Cross-sex socialization? 总被引:2,自引:0,他引:2

Are sisters of twin brothers behaviorally or physiologically masculinized? Prenatal exposure to their brothers' androgens and postnatal socialization experiences unique to girls growing up with twin brothers might influence their attitudes, pubertal development, and reproductive histories. To investigate, we studied age- and cohort-matched samples of Finnish sisters from same-sex and opposite-sex twin pairs. Using data from two ongoing longitudinal studies of consecutive birth cohorts of Finnish twins, we assessed pubertal development at ages 11 and 14 and endorsement of attitudes associated with femininity at age 16. We also studied fertility in Finnish women from same- and opposite-sex twin pairs born from 1958 through 1971, obtaining information on their child-bearing histories when they were ages 15 to 28. Results of each comparison were unambiguously negative: There was no evidence of differences between sisters from same- and opposite-sex twin pairs, and thus, no evidence of either androgenization or cross-sex socialization. 相似文献
