Hudson's Pictures in Pandora's Box

Abstract

Highly sophisticated Europeans and unsophisticated Zambians responded to two of Hudson's Pictorial Perception Test stimuli displayed in "Pandora's Box. " Neither the application of Hudson's nor of "Pandora's Box" procedure yielded evidence of depth perception in the case of the Zambian samples. The European sample responding to the "Pandora's Box" procedure did perceive depth in the stimulus containing both overlap and familiar size cues, and failed to do so in response to the stimulus containing familiar size cues only. The hypothesis that the two populations will not differ on the task and will both fail to perceive depth as measured by "Pandora's Box" was therefore rejected, as was the hypothesis that the reduction of background cues occurring in the box would lead to an increase in the number of 3-D responses.
