Robert Fantz: Visual Perception

Visual perception is the way in which humans see things around them. This form of perception develops from infancy to adulthood. The way in which we see things has been researched by many theorists, one of which i am going to discuss, is Robert Fantz.
Robert Fantz: Visual Perception:
Robert Fanta was an American developmental psychologist who pioneered several studies into infant perception.
Early research:
He began by investigating the perception in chicks. He presented chicks with a number of small objects of different shapes and recorded the number of pecks the chicks made at each of these objects. He hatched them in darkness and tested them the very first time they were exposed to the light so that he would be absolutely sure that no learning had taken place. He

Trial and error may mean they experience falls, due to misjudgement, where they learn from their mistakes.
The visual cliff:
Gibson and Walk designed a piece of experimental equipment which they call the visual cliff. This consists basically of heavy glass which is supported a foot or more above the floor. A piece of patterned material is placed flush to the undersurface of half of the glass. Gibson and Walk tested
36 infants aged from 6 to 14 months on the visual cliff. Each child was placed on the centre and his mother called him to her from the cliff side and then the safe side. All of the 27 infants who did move crawled out on the safe side at least once: only three of them crawled over the cliff
