Four target shapes, a control stimulus (circle) and one each representing geometrical (arrow), representational (car), and symbolic (cross) implied movement were presented to 10 children in each of five age groups of boys and girls (4, 6, 8, 10, 12 yr.) in an autokinetic movement task. While there were no differences in direction of perceived movement with regard to the control stimulus (circle), all other target shapes showed a decrease in the effects of implied movement with increases in age. The minor sex differences were not reported. 相似文献

The number of reported changes in direction of autokinetic movement was assessed as a function of color of the light that served as stimulus, viewing angle (0, 30, or 60 deg of displacement from straight ahead), and dark adaptation. Color and dark adaptation had no significant main effect on the number of reported changes in direction for the red and yellow lights, but viewing angle was inversely related to the number of reported changes. For the blue-green light, atypical effects of viewing angle and dark adaptation were found. 相似文献

Both the autokinetic illusion (AKI) and involuntary eye movements when a fixation point goes off have been attributed to unmonitored drift eye movements which result from constant features of the oculomotor system. Pilot studies confirmed that the visual directions where these effects had no directional bias, the position of random autokinetic movement (PRAKM) and the physiological position of rest (PPR), were highly correlated and reliable. The more precise main experiment showed that they were usually, but not always, stable and identical. Drifts are therefore not totally due to stable features of the oculomotor system but are a compound of several slow responses which can differ with both stimulus conditions and time. They are not all equally unmonitored. 相似文献

Eyeblinking during autokinetic movement observed by one subject living in the up-down inverted visual world, was investigated. The subject wore frame-spectacles (without prisms) for the first two days and then wore up-down inverting spectacles (with prisms) for the next four days, followed by the resumption of the former frame-spectacles for one day. Eyeblinks during autokinetic movement were measured by using vertical EOG. Analysis showed (1) the occurrence of eyeblinking during autokinetic movement was not influenced by living in the up-down inverted visual world; (2) the frequency of eyeblinking during autokinetic movement significantly decreased with successive days of observation. 相似文献
