Two experiments were designed to investigate the factors involved in the visual facilitation of auditory localization. In both experiments, adult human Ss pointed to targets in a variety of visual conditions. The results of the first experiment showed that target-directed eye movements were important. In the second experiment, eye localization was assessed, along with pointing localization. Both eye and hand localization of the hidden auditory targets were better when target-directed eye movements were made in a lighted environment than when made in the dark. Data also suggested that Ss have better knowledge of their eye position in the light. Possible mechanisms for the involvement of eye movements were suggested, and the theoretical importance of the results was discussed.  相似文献

The mathematics attitudes (determined by ratings on the Fennema-Sherman Mathematics Attitudes Scales) of ninth grade girls of similar intellect who subsequently took one to four years of college preparatory math were compared in 1975 and 1978 (n = 84). Math enrollment groups differed significantly on the following scales: Usefulness of Mathematics, Confidence in Learning Mathematics, Teacher (perceived attitude toward the student as a learner of mathematics), and Effectance Motivation in Mathematics as assessed both in Grades 9 and 12, and on the Math as a Male Domain Scale as assessed in Grade 12. From Grade 9 to 12, scores on the Attitude toward Success in Math Scale became significantly more positive.  相似文献

This study examined the proposition that blacks and whites make dispositional attributions for an in-group's positive behaviors and an out-group's negative behaviors. The study also examined whether this positive in-group bias was caused by dislike of the out-group or belief in a stereotype. Thus, blacks and whites made attributions to black and white others who succeeded or failed on tasks for which there was either no stereotype or a more negative stereotype of whites than of blacks. An out-group other's failure on both tasks was attributed to lack of ability more than was an in-group other's failure. This finding suggests that the in-group bias is caused by dislike of the out-group. Furthermore, in success conditions subjects' attributions to the in-group or out-group other did not differ. It was suggested that these attributions may result from a combination of an in-group bias and a polarized appraisal.  相似文献

Five- and six-day old chicks were found to prefer a complex stimulus to a simple one, whilst 2-day old ones showed no such preference; but a red stimulus, whether simple or complex, tended to be preferred at both age levels when it was paired with a non-coloured complex stimulus. Preference for complexity may be usefully viewed in any species in the context of the behavioural development of the individual.  相似文献

Two neonatal intensive care units (NICU) were observed every 15 minutes for at least 72 consecutive hours. Although infants on both NICUs were exposed to considerable amounts of stimulation, there were differences between the units for each environmental measure in the amount of stimulation and/or the pattern of circadian periodicity. The two NICUs also differed in the amount of time infants spent in various states and in the pattern of state periodicity. In general, the diurnal rhythms of the infant states were associated with the diurnal rhythms of different environmental events; furthermore, the patterns of association were not the same on the two NICUs. The results point to potential problems in depicting a “typical” NICU. More importantly, they suggest that the environmental of NICUs has a recognizable influence on aspects of their inhabitants' behavior and that the nature of influence is different from NICU to NICU. The effects are potentially significant for physical, social, and cognitive development.  相似文献

Media psychologists have long puzzled over how individuals can experience enjoyment from entertainment such as tragedies that often elicit profound feelings of sadness. The present research examines the idea that a focus on “meaningful” entertainment and affective responses identified as “elevation” may provide a framework for understanding many examples of sad or dramatic entertainment. The results of this study suggest that many types of meaningful cinematic entertainment feature portrayals of moral virtues (e.g., altruism). These portrayals, in turn, elicit feelings of elevation (e.g., inspiration) that are signified in terms of mixed affect and unique physical responses (e.g., lump in throat). Ultimately, elevation also gives rise to motivations to embody moral virtues, such as being a better person or helping others.  相似文献

Early adolescence represents a particularly sensitive period in the life of young learners, which is accompanied by an increase in school alienation. Due to its harmful nature (Hascher and Hadjar...  相似文献
