Responses of 289 university students to Belicki's Nightmare Distress Questionnaire and the Stress-related Health Problems Scale were used to test the hypothesis that persons who score high on nightmare distress are more likely to report psychological problems. Since relative to the Low Nightmare Distress group, the High Nightmare Distress group scored significantly higher on all seven of the sets of symptoms that are measured by the Stress-related Health Problems Scale, this hypothesis was supported. 相似文献

Three experiments were performed to test Smith, Ward, and Schumacher’s (1993) conformity hypothesis— that people’s ideas will conform to examples they are shown in a creative generation task. Conformity was observed in all three experiments; participants tended to incorporate critical features of experimenter-provided examples. However, examination of total output, elaborateness of design, and the noncritical features did not confirm that the conformity effect constrained creative output in any of the three experiments. Increasing the number of examples increased the conformity effect (Experiment 1). Examples that covaried features that are naturally uncorrelated in the real world led to a greater subjective rating of creativity (Experiment 2). A delay between presentation and test increased conformity (Experiment 3), just as models of inadvertent plagiarism would predict. The explanatory power of theoretical accounts such as activation, retrieval blocking, structured imagination, and category abstraction are evaluated. 相似文献

Two studies examined the role of religious commitment in moderating the relationship between positive affect (PA) and meaning in life. In Study 1, Sample 1, religiosity was found to moderate the relationship between naturally occurring PA and meaning in life, showing that high levels of religiosity attenuated the effects of PA on meaning in life. In Study 1, Sample 2, religiosity similarly moderated the effects of induced mood on meaning in life. In addition, this pattern of results was shown to be unique to meaning in life compared to another life domain (life satisfaction). In Study 2, subliminally priming Christians with positive religious words (e.g., “Heaven”) was further shown to weaken the association between PA and meaning in life, whereas subliminal primes of negative religious words (e.g., “hell”) weakened the association between religious commitment and meaning in life. A competition of cues model is proposed to account for these effects. 相似文献

The following paper describes a new technique for simulating peripheral field losses in virtual environments to study the roles of the central and peripheral visual fields during navigation. Based on Geisler and Perry's (2002) gaze-contingent multiresolution display concept, the technique extends their methodology to work with three-dimensional images that are both transformed and rendered in real time by a computer graphics system. In order to assess the usefulness of this method for studying visual field losses, an experiment was run in which seven participants were required to walk to a target tree in a virtual forest as quickly and efficiently as possible while artificial head and eye-based delays were systematically introduced. Bilinear fits were applied to the mean trial times in order to assess at what delay lengths breaks in performance could be observed. Results suggest that breaks occur beyond the current delays inherent in the system. Increases in trial times across all delays tested were also observed when simulated peripheral field losses were applied compared to full FOV conditions. Possible applications and limitations of the system are discussed. The source code needed to program visual field losses can be found at lions.med.jhu.edu/archive/turanolab/Simulated_Visual_Field_Loss_Code.html. 相似文献

Source monitoring for valenced materials has received very little attention from researchers interested in the residual effects
that emotion can have on memory. The three previous studies that examined memory for valenced material found a source-monitoring
enhancement effect. By contrast, we used two different combinations of sources and found a novel, consistent source-monitoring
deficit for valenced words as compared with neutral ones. In addition, this memory deficit for contextual details did not
consistently covary with item memory. We assert that it is possible to obtain an effect in which heightened attention toward
valenced material reduces the binding of contextual details into memory. 相似文献

College student subjects performed a sequential typing task requiring bilaterally synchronized movements (Experiment 1) or unilaterally synchronized movements (Experiment 2) singly, and concurrently with silent and vocal rehearsal of verbal lists varying in redundancy. Rehearsal interfered with bilaterally synchronized movements more when the right hand was leading the sequence than when the left hand led, and with movements of the right more than the left hand in unilaterally synchronized movements. Results are interpreted in terms of intrahemispheric and general capacity competition between the concurrent performances. 相似文献
