Two experiments showed the influence of perceptual set on the perception of subjective contours. In the first, the perceived shape of a subjective-contour figure (a minimal version of the Ehrenstein configuration) was varied by altering the observer’s viewing set. The second experiment showed that apparent depth emerged in subjective-contour figures when observers were set to perceive the illusory contours. 相似文献

The purpose of this study was to examine the reciprocal relationships between locus of control and job attributes of a representative sample of 1383 employees in a large Australian city. It was predicted that employees with an internal locus of control would attain jobs higher on skill-utilization, influence and income than those attained by employees with an external locus of control. It was also predicted that jobs involving high skill-utlization, influence and income would induce greater internal control beliefs than those low on skill-utilization, influence and income. Locus of control was measured using Rotter's scale (Rotter, 1966). Reciprocal causation was assessed using two-stage least squares analysis. For the total sample, it was found that locus of control and job attributes were reciprocally determined. However, locus of control was not related to influence when skill-utilization and income were controlled. When the sample was split on the basis of gender and marital status, the predicted relationships between locus of control, skill-utilization and income were found for married men only. For married women, locus of control was neither a determinant of job attributes nor an outcome of job experience. These sub-group differences were interpreted in terms of differences in job tenure, work values and occupational opportunity. 相似文献

Performance of disturbed hyperactive and nonhyperactive children on an objective measure of hyperactivity 总被引:3,自引:0,他引:3
Twenty hyperactive emotionally disturbed children (6–11 years) and a matched sample of nonhyperactive emotionally disturbed children were selected from the population of a therapeutic day treatment facility on the basis of teacher ratings. They were administered the Matching Familiar Figures Test-20 and were rated on several scales of impulsivity and/or hyperactivity. Each subject was required to perform on the Delay Task of the Gordon Diagnostic System, which required them to inhibit behavioral responding on a temporally based schedule (DRL-6) in order to win points. Children classified as hyperactive, whether by one or more criteria, were relatively unable to refrain from emitting a high number of nonreinforced responses. Moreover, these performance differences persisted regardless of age or IQ and were stable over the 8 minutes required to complete the test.The authors gratefully acknowledge the efforts of the following members of the Institute of Clinical Psychology, University of Virginia: Richard Abidin, Ann Loper, Ronald Reeve, and Sherry Kraft.

This paper brings together, in the context of individual-differences theory, two developing themes in schizophrenia research. One concerns the manifestation, in normal people, of ‘psychotic’ characteristics and their measurement using scales which, unlike the Eysenck P scale, draw their items from the clinical symptomatology of psychosis. Recent work on the so-called ‘borderline states’ is considered especially relevant and a new two-scale questionnaire (STQ) is described which was modelled on the current distinction, in DSM-III, between ‘schizotypal personality disorder’ and ‘borderline personality disorder’. The second theme addressed concerns the possible biological basis of individual differences in ‘schizotypy’. It is argued, in the light of some emerging views about the nature of schizophrenia, that this may lie in the functional and structural properties of hemisphere organization. A suggested strategy for evaluating this theory is an examination of the performance of schizotypal normal Ss on tests of hemisphere function. 相似文献

Two experiments are reported comparing high and low schizotypal normals on divided field tasks of (a) letter recognition and (b) local-global processing. On the former, low schizotypal Ss showed an expected right visual-field superiority, whereas high schizotypal Ss showed the opposite, in that respect resembling schizophrenic patients. A similar reversed asymmetry was found when the two personality types were compared for local and global processing of letter stimuli, high schizotypals being especially unusual in showing superior local processing for stimuli presented in the left visual field. The results are taken as providing further support for the theory of schizotypy put forward in a previous paper. 相似文献

Pro-Kremlin disinformation campaigns have long targeted Ukraine. We investigate susceptibility to this pro-Kremlin disinformation from a cognitive-science perspective. Is greater analytic thinking associated with less belief in disinformation, as per classical theories of reasoning? Or does analytic thinking amplify motivated system 2 reasoning (or “cultural cognition”), such that analytic thinking is associated with more polarized beliefs (and thus more belief in pro-Kremlin disinformation among pro-Russia Ukrainians)? In online (N = 1,974) and face-to-face representative (N = 9,474) samples of Ukrainians, we find support for the classical reasoning account. Analytic thinking, as measured using the Cognitive Reflection Test, was associated with greater ability to discern truth from disinformation—even for Ukrainians who are strongly oriented towards Russia. We find similar, albeit weaker, results when operationalizing analytic thinking using the self-report Actively Open-Minded Thinking scale. These results demonstrate a similar pattern to prior work using American participants. Thus, the positive association between analytic thinking and the ability to discern truth versus falsehood generalizes to the qualitatively different information environment of postcommunist Ukraine. Despite low trust in government and media, weak journalistic standards, and years of exposure to Russian disinformation, Ukrainians who engage in more analytic thinking are better able to tell truth from falsehood. 相似文献

Using heat as a negative reinforcer was shown to be highly efficient in producing a discriminative response in Long-Evans rats. Heat failed to generate the emotional responses usually associated with shock as an aversive stimulus. In a separate study, using the heat-training procedure, age differences in the learning facility of Swiss/ICR (Ha) mice were detected. 相似文献

A comparison of type II operating characteristics derived from confidence ratings and from latencies
Leonard Katz 《Attention, perception & psychophysics》1970,8(2):65-68
On each of a series of trials, S judged two stimuli to be the same or different. S then made a confidence rating of his judgment. The difficulty of discrimination and feedback of response information (latency and correctness) were manipulated. Feedback had no effect. Latencies conditional on confidence rating decreased with increasing confidence and remained relatively constant with changes in discrimination difficulty. Type II operating characteristics were derived from latencies and from confidence ratings; both appropriately reflected differences in task difficulty. 相似文献

Previously reported experiments demonstrated changes in the relation of visual direction to retinal locus for stimulation during voluntary saccades as compared to this relation before saccade initiation. The quantitative features of these results led to the prediction, confirmed in the present experiments, that there are shifts in visual direction for stimulation presented before the saccade itself. In the present report, monotonically increasing shifts were mapped with stimuli presented as early as 240 msec before the saccade up to the saccade itself. Such shifts cannot be accounted for readily by “inflowing” processes, and while “outflowing” processes seem to be implicated, their quantitative characteristics would need to be considerably different from those required by classical outflow theories. 相似文献
