PSY 3108 Lecture Notes - Lecture 1: Absolute Threshold, Naturalistic Observation, Smooth Pursuit
Document Summary
Basic concepts in perception: process of perception, measurement methods for simple perceptions. Schizophrenia and smooth pursuit eye movements: schizophrenic individuals have different visual perceptions, among other things. They don"t follow movements smoothly with their eyes (lagging and attempting to catch up). Iq and perception: iq declines with age. Most of our aspects decline with age and this contributes to the data representing iq decline. Ex) block task in an iq test which is impacted by vision, or reverse-repeating task which subject might not hear properly. Loss of iq is actually a loss of hearing, vision, touch, etc. Na ve realism: idea that perception is easy and not complex. I believe it because i see it", ex) optical illusions. Methods in perception research: qualitative (big picture research, little analysis of detail) and quantitative (understanding the details, breaking down the pieces and analyzing them). Threshold seeking methods are ways of seeking the extreme abilities.
