摘要: <正> 問題 大小知觉是視知觉心理学中重要問題之一,也是人在实践活动中所經常接触的問題。前人研究表明,大小知觉总是与知觉对象的距离成一定的关系,并提出所謂大小-距离不变假設(Size-Distance Invariace Hypothesis)来說明这种現象。在一般情况下,对象离开观察者愈远,网膜视象随距离按比例縮小,而观察者所知觉的大小却仍接近对象的原来实际大小(物理大小),也就是說大小知觉保持着一定的恆常性。这是大小知觉与距离关

Abstract: Studies were carried out with 48 Ss on size perception. The standard stimulus was a balloon (diameter: 38.2 cm.) placed at distances of 50, 100, 150, 200 and 250 metres from S, the comparison stimulus being another balloon placed by the side of S, and adjustable in size by S operating a valve, Ss were instructed to make size judgments with a naive attitude.It was found that when the observer sat erect, size constancY broke down strikingly at 200 and 250 metres, but only a few Ss made over-estimations. When the observer was in a prone position (raising his head and eyes) and in a supine position (lowering his head and eyes), the perceptual size shrank in comparison with the results obtained in the erect observations. The prone position caused a more marked decrease in perceptual size, and observations made in a fully prone position yielded smaller perceptual sizes than those made in a semi-prone position, When the supine observer bent his head backward to see the stimulus in an inverse visual field, the perceptual size decreased to a minimum, and he reported at the same time an increase in perceptual distance. The results of this study were discussed in relation to the moon illusion. It is suggested that a normal relation between the postural position of the observer and the environment plays an important role in size perception, the distortion of which also causes a breakdown of the constancy phenomena.
