Detailed explanation-1: -Background and aim: The aim of this experiment was to investigate the physiological and behavioural effects of a limited visual experience and whether brain development/plasticity occurs due to experiences rather than nature.
Detailed explanation-2: -Blakemore and cooper randomly allocated and raised 2 week old kittens in either a horizontal or vertical striped environment for 5 hours per day for five months. The diameter had a perplex floor. so the kitten can move around freely. No edges or corners.
Detailed explanation-3: -What did Blakemore and Cooper conclude from the study? The changes in neurons in the visual cortex were the result not of degeneration but of brain plasticity, as neurons matched their sensitivity to the stimulation they received.
Detailed explanation-4: -Brain development is affected by early experiences and environmental factors rather than just genetics and there is clear evidence of brain plasticity – ‘the visual experience of these animals had modified their brain’ and therefore has serious perceptual consequences.
Detailed explanation-5: -Blakemore and Cooper (1970) Impact of early visual experience Biological An early example of research into brain plasticity, in which evidence is put forward of the impact that the visual environment has on cats’ brains (specifically their visual neurons).
