The Nature of, Perceptual Illusions
Perceptual illusions are defined as consistent and persistent discrepancies between a physial state of affairs and its representation in consciousness. It is argued that for the most part these discrepancies occur mainly as a consequence of the activation of perceptual processes by contrived, artificial stimuli. When activated by their normal or natural stimuli the processes result in veridical perception. When activated by artificial or unnatura…
Infant perception of the invariant size of approaching and receding objects
After habituation of looking at an object that repeatedly approached and receded through 50 cm along the medial axis, infants of about 18 weeks of age were presented with both the same moving object and one of a different size falling within the same range of visual angles as those projected during habituation. The starting point for movement varied widely from trial to trial to desensitize subjects to a range of changing distances and visual ang…
The Components of the Poggendorff Illusion
An explanation of the Poggendorff misalignment illusion in terms of three basic components, the horizontal-vertical, longitudinal-transverse and obtuse angle effects, is proposed. It is argued that these effects may either singly or jointly give rise to an apparent elongation-contraction of the space between the aligned elements with consequent change in apparent oblique direction. Experimental evidence for the involvement of the three components…

Studies in perception
Even the most cursory study of the academic psychologist as a species will reveal that his life-cycle falls into four natural phases
Sensory adaptation and behavioral compensation with spatially transformed vision and hearing
An analysis of spatial transformations of perceived space is made in terms of angular and parallel modifications of the median, horizontal, and frontal planes of O, and the perceptual and behavioral outcomes of such transformations examined. It is argued that there are 2 independent outcomes: behavioral compensation and sensory spatial adaptation with aftereffect. The 1st can be regarded as a special case of motor learning similar to that studied…
Hue Differences and Brightness Differences as Determinants of Figural After‐effects
Earlier published studies of the figural after‐effect using stimulus patterns in which there was no difference in brightness between the inspection figure and its background report inconsistent results. The possibility of more than one type of visual after‐effect following protracted fixation of a figure is advanced as an explanation of this inconsistency. In the three experiments described the frequency of occurrence of the figural after‐effect …
