Investigated depth perception with various tribal groups in Africa using pictures where cues help the viewer to perceive depth.
lThe picture contains depth cues: overlapping objects and relative size, height in the visual field. lHudson suggested a correct interpretation is that the hunter is trying to spear the antelope, which is nearer to him than the elephant. An incorrect interpretation is that the elephant is nearer and about to be speared. lParticipants were asked: l‘What do you see?’
‘Which is nearer, the antelope or the elephant?’
‘What is the man doing?’' lThe results indicted that both children and adults found it difficult to perceive depth in the pictures.
