Document Summary
Occurs when we have damage to primary pathway of vision (ex. visual cortex) Taking a block and fitting it into a slot: will accurately shaping their hands to grab block before even touching it. If we lesion visual cortex and lesion parietal lobe, action blindsight goes away: tms, uses a magnetic to polarize and depolarize neurons in brain, can temporarily shut down areas of brain. Intact perceptual judgements (can say what colour an object is without ever seeing it) Among mammals, only humans have colour vision, so how did primates evolve to get colour vision. Primate colour vision is especially well suited to distinguish red and yellow against a green background. Additionally, the ability to perceive colour is an important advantage for detecting predators or prey against a background, determining the ripeness of fruit, the richness of soil or even using the colour of sunsets as a means to predict weather.
