Size-constancy as dependent upon angle of regard and spatial direction of the stimulus-object
article
Three experiments were set up to assess the influence of both the angle of regard and the spatial direction of a stimulus-object upon the size-constancy ratio at distances up to 40 m. It was shown that both factors have an effect in the sense that the normal, straight forward, regard and the horizootal direction yield a higher size-constancy ratio than, respectively, the elevated regard and the vertical direction. Prolonged monocular viewing conditions decrease the effect of the angle of regard. The suggestion is made that the use of size- and distance-cues is learned mainly in situations where O looks straight ahead at objects in a horizontal plane, and that this learning is generalized to situations of the same sort. When O is looking with extreme angle of regatd, or finds himself viewing in unusual spatial direction, he makes less optimal use of the cues available.
