We investigated the effects of colors on vection induction. Expanding optical flows during one’s forward self-motion were simulated by moving dots. The dots and the background were painted in equiluminant red and green. Experiments 1 and 2 showed that vection was weaker when the background was red than when the background was green. In addition, Experiment 3 showed that vection was weaker when the moving dots were red than when the dots were green. Experiment 4 demonstrated that red dots on a red background induced very weak vection, as compared with green dots on a green background. In Experiments 5 and 6, we showed that the present results could not be explained by a luminance artifact. Furthermore, Experiment 7 showed that a moving red grating induced weaker vection than did a green one. We concluded that a red visual stimulus inhibits vection. 相似文献

In this paper, we will examine and untangle a conflict mainly between a developmental psychologist, Martin Hoffman and a social
psychologist, Daniel Batson. According to Hoffman, empathic distress, a vicarious feeling through empathy, is transformed
into an altruistic motivation. Batson and others on the other hand, criticize Hoffman, claiming that empathic altruism has
no relation with empathic distress. We will point out some problems with Batson’s position by referring to the results of
fMRI experiments that suggest empathic distress and empathic altruism share a common basis, and defend Hoffman’s argument.
This will also offer new insights into the evolution of empathy.

Recent studies suggest that North American adults exhibit a focused strategy of attention that emphasizes focal information about objects, whereas Japanese adults exhibit a divided strategy of attention that emphasizes contextual information about objects. The current study investigated whether 4- and 5-, 6- to 8-, and 9- to 13-year-old North American and Japanese children exhibit these divergent attention strategies. Two experiments suggest that those older than 6 years of age exhibit measurable cultural differences in attention, whereas 4- to 6-year-olds do not. We suggest that sociocognitive development and socialization experiences that occur around 5 to 7 years of age may foster the development of cultural strategies of attention. 相似文献

The goal of this study was to examine the effect of joint visual attention on infants' behavior during subsequent events.
Thirty-seven mother-infant (aged from 9 to 13 months) pairs were twice shown a pair of line drawing stimuli on a computer
screen. For the control group, the mother never paid attention to the stimuli. For experimental group 1, the mother pointed
to one stimulus in the first presentation but did not point to it in the second presentation. The infants gazed longer at
the stimulus pointed to by their mothers in the first presentation. In the second presentation, during which mothers did not
attend to the stimuli, infants gazed longer at the stimulus which had been pointed to by the mothers in the first presentation.
In experimental group 2, one of two stimuli blinked during the first presentation but not the second presentation. Infants
gazed for longer at the blinking stimulus in the first presentation, but there was no difference in looking time toward the
two stimuli in the second presentation. These results suggest that joint visual attention affects infants' looking behavior
during subsequent events, and that simple stimulus change does not.

Hand preferences of two Japanese macaques were observed in five differing tasks: simple reaching for food on a platform; choosing of boxes with pieces of apple; mirror-guided reaching (taking food from the box, key pressing, key tracking). Though these were visually guided tasks, the macaques showed different hand preferences.

This study systematically investigates changes in CNV waveform shape and resolution time that result from the presentation of facilitatory, inhibitory, or no motor response (MR) information simultaneously with the warning (S1) or imperative (S2) stimulus of the S1-S2-MR CNV paradigm. Analyses indicate that the simultaneous presentation of S1 and information to produce or inhibit a MR attenuates initial CNV development. Further, when the S1 information is inhibitive, CNV development is retarded throughout. The contribution of an inhibitory psychological process during CNV development is proposed. The data also indicate that CNV resolution time is not dependent on the presence of a motor response. It is suggested that CNV resolution time is indicative of psychological completion or closure. 相似文献

The present study was designed to study generalization and differentiation and to check the relation between heart rate and blood pressure in cardiovascular conditioning. Five naive mongrel dogs were presented with 10 sec 1000 cps tone regularly reinforced with 0.5-sec shock to a left foreleg. Four other 10-sec tones (600, 800, 1200, 1400 cps), never reinforced, were administered in a randomized and counterbalanced fashion using a differential reinforcing technique. The response measures were heart rate and three indices of blood pressure,i.e., systolic, diastolic, and pulse pressures.“Initial response” of heart rate showed rapid tachycardia to all tones, with no generalization and differentiation among five tones.“Terminal response” clearly indicated generalization gradients that tachycardia to 800 and 1200 cps tones were higher than those to 600 and 1400 cps tones, respectively. Some differences were noted among systolic, diastolic, and pulse pressures, with pulse pressure showing a trend of generalization and differentiation in the“initial response.” No statistical difference, however, was obtained in blood pressure scores. Beat-by-beat analyses of correlations between heart rate and diastolic blood pressure showed that the correlations successively decreased during the“terminal response.” Overall correlations between heart rate and three indices of blood pressure were obtained, with the highest correlation between heart rate and pulse pressure. Considering the above results in relation to the classical conditioning theory, it was tentatively concluded that“initial response” includes non-conditional factors, while“terminal response” reflects mainly a true conditional response, particularly, at a long CS-US interval. This interpretation leads to the hypothesis that conditional response with a short CS-US interval may attain better conditioning scores in terms of the summation effect between a non-conditional factor and a true conditional factor. 相似文献
