- Discuss the development of depth/distance perception and/or visual constancies (8+16)
- Are perceptual abilities innate or learned through the environment?
- Depth/Distance
- Gibson + Walk (1960) Visual Cliff
- The infants were placed in the centre of the cliff and the parents called to them from either the deep or shallow side.
- They found out of the 36 infants; 27 crawled to their parents from the shallow side, 3 crawled over the deep side and 9 refused to move. Distress shown from the deep side
- Concluded that infants must have good enough percep. skills to notice the depth change.
- They found out of the 36 infants; 27 crawled to their parents from the shallow side, 3 crawled over the deep side and 9 refused to move. Distress shown from the deep side
- But we can't draw a causal conclusion from these results, it is equally plausible assumption that a fear of falling is innate, again we cant reach this conclusion from the study
- Aswell as this, in order for the babies to take part in the study, they have to be at least 6 months in order to be mobile.
- During this 6 months, they could have had time and experience to learn about depth perception and/or the dangers of falling
