Some comparative experiments on the dichoptic induction of the movement aftereffect (MAE) contingent on color and the MAE contingent on orientation are reported. Colorcontingent movement aftereffects could be evoked only when the eye which had viewed color during adaptation also viewed color during test sessions. When the apparent color of the test field was changed by binocular color rivalry, contingent movement aftereffects (CMAEs) appropriate to the suppressed color were reported. After dichoptic induction of the orientation-contingent MAE, aftereffects could be obtained whether the eliciting gratings and stationary test fields were presented together to either eye alone or were dichoptically viewed. 相似文献

A range of variants of the Schröder staircase was generated by computer, giving quantifiable changes of perspective and the option of adding appropriate texture to the steps of the staircase. Increases in perspective and the addition of texture gradients led to increases in the proportion of viewing time during which the percept appropriate to the perspective was reported. It is suggested that this might be a useful method of studying the processing of depth information. 相似文献

This study investigated whether an observed inverse relationship between self-stimulation and learning in autistic children is due to a physical inability of the subject to use the same body part for self-stimulation and task responding, or whether self-stimulation “distracts” the subject from task responding. Four actively self-stimulating autistic children were taught two discrimination tasks; one required a response that physically interferred with their self-stimulation; the other did not. Results were: (a) all subjects responded similarly across both tasks; (b) the three subjects with higher mental age scores learned both tasks without external suppression of self-stimulation; and (c) none of the subjects showed an inverse relationship between self-stimulation and learning. The study demonstrated that elimination of self-stimulation is not a necessary prerequisite for the acquisition of a new behavior in all autistic children. 相似文献

In deciding that two items come from the same category, subjects were delayed if the items were presented as a word and a picture, as compared with two words or two pictures. Subjects were not delayed if the items were not to be compared. Hence, the delay appears to occur during the retrieval and comparison of know ledge about the items, not during their perceptual analysis. The results suggest that there are two distinct codes involved in the categorization of words and pictures, rather than a single code. 相似文献

Equity research has been based on defining formulae that do not necessarily imply the hypotheses thought to have been derived from them and that are not consistent with empirical data cited as supporting equity theory. Neither Adams' (1965) ratio definition nor Walster et al.'s (1970, 1972, 1973) formula satisfy the fundamental criterion that, when equity holds, outcome should be an increasing function of input. Six formulae that do satisfy this fundamental criterion (including Adams' ratio definition restricted to positive ratios, Walster et al.'s revision of their formula, three formulae generated by a simple constructive procedure, and an exponential definition) are compared with respect to 11 other criteria and with respect to their predictions of the results of two thought experiments. 相似文献

We asked whether high levels of religiosity are inconsistent with a high valuation of science. We explored this possibility in three countries that diverge markedly in the relation between the state and religion. Parents in the United States (n = 126), China (n = 234) and Iran (n = 77) completed a survey about their personal and parental stance towards science. The relation between religiosity and the valuation of science varied sharply by country. In the U.S. sample, greater religiosity was associated with a lower valuation of science. A similar but weaker negative relation was found in the Chinese sample. Parents in the Iranian sample, by contrast, valued science highly, despite high levels of religiosity. Given the small size of our United States and Iranian samples, and the non-probabilistic nature of our samples in general, we caution readers not to generalise our findings beyond the current samples. Despite this caveat, these findings qualify the assumption that religiosity is inconsistent with the valuation of science and highlight the role of sociocultural context in shaping adults' perception of the relation between religion and science. 相似文献
