Two shapes of either the same or different color will seem to be in smooth apparent motion with like-colored mates, at proper conditions of flash timing and spacing. An experiment is reported in which the condition was tested for unlike-colored pairs, for example red-green alternated with green-red. The question of interest was how the visual system would resolve the disparity of color. An 'intelligent' solution would rotate the shapes in three dimensions. Like-colored and unlike-colored parts were found to move and transform similarly, however, the resolution being dependent more upon timing than upon color. The motion of intelligence as it might be applied to vision is discussed in light of these results.  相似文献

Serial pattern learning was investigated in a variation of the task introduced by Nissen and Bullemer (1987). We presented an asterisk at 1 of 4 spatial locations on each trial, and Ss either responded with a keypress or observed the event. The first 4 blocks contained 10 repetitions of a 10- or 16-element pattern, and the 5th block contained a random sequence. The difference in response time on the 5th random block and the previous patterned block served as an indirect measure of pattern learning. A direct measure was obtained in a final test block in which Ss predicted the next asterisk position. Equivalent learning occurred for responding and observing with indirect measures, but observation was superior with direct measures. These findings indicate that knowledge of serial order can develop through simple perceptual experience, and this is more available to deliberate recall than is knowledge acquired while responding.  相似文献

The present study explored the availability of flexible work arrangements (FWA) and their relationship with manager outcomes of job satisfaction, turnover intentions, and work‐to‐family conflict (WFC) across country clusters. We used individualism and collectivism to explain differences in FWA availability across Latin American, Anglo, and Asian clusters. Managers from the Anglo cluster were more likely to report working in organisations that offer FWA compared to managers from other clusters. For Anglo managers, flextime was the only FWA that had significant favorable relationships with the outcome variables. For Latin Americans, part‐time work negatively related with turnover intentions and strain‐based WFC. For Asians, flextime was unrelated to time‐based WFC, and telecommuting was positively associated with strain‐based WFC. The clusters did not moderate the compressed work week and outcome relationships. Implications for practitioners adopting FWA practices across cultures are discussed.  相似文献

We describe three experiments testing treatments to promote the performance of health-protective dental behaviors. Subjects included 55 women from an introductory psychology course (Experiment 1), 45 men and women (Experiment 2), and 81 older-than-average students identified as at risk for gum disease (Experiment 3). The interventions, derived from social cognitive theory, included health education, skills training, and self-monitoring. In each study, we examined the contribution of additional treatment components, including social support (Experiment 1), intensive contact (Experiment 2), and flexible goal setting (Experiment 3). Across experiments, the behavioral results were remarkably similar: Subjects exhibited excellent adherence while in the study but, at follow-up, reported behavior that differed little from baseline. We discuss parallels between attempts to promote health-protective dental behaviors and other health-promotion programs, and we describe different perspectives from which to address the problem of creating healthy habits.  相似文献
