Procedure 1
Gibson and Walk designed a simple experimental set-up the visual cliff to investigate depth perception in babies and other young animals.
Procedure 2
The apparatus enabled the researchers to control optical, auditory and tactile stimuli, and also to protect participants.
Procedure 3
The visual cliff consisted of a large glass sheet that was supported 30cm or more above the floor.
Procedure 4
On one side, a sheet of patterned material was placed directly beneath the glass. On the other side, the patterned material was laid on the floor; this side of the apparatus formed the visual cliff.
Procedure 5
The participants (infants or young animals) were placed on the centre board that lay between the shallow and deep sides.
Procedure 6
The participant was then encouraged to move across the shallow and the deep sides in order to observe whether they would refuse to crawl over the drop.
