Document Summary
Computer analogy - an ability to systematically convert input to output. Emphasises basic mental processes: attention, sensation, perception & memory. Perception interpretation everything you do depends on your ability to sense and perceive the world around you. Perception interpretation: attention the ability to focus. Methods of studying infant perception: habituation, discrimination learning (cid:858)lear(cid:374)i(cid:374)g to (cid:271)e (cid:271)ored(cid:859) Preferential looking: duration of looking at one of a pair. Physiological responses: heart rate, observation of eye movements. Evoked potentials: electrical conductivity of the brain, operant conditioning response to one stimulus in a pair following reinforcement. Infant vision basic capacities are present at birth can detect changes in brightness. Week 5 lecture 5 track a slow-moving object lack visual acuity: ability to perceive detail visual accommodation, ability to focus on objects at different distances, optimal distance: about 20-25cms. Takes 6 months to 1 year before can see as well as an adult. Colour vision present at birth mature at 2-3 months.
