PSY270H5 Lecture Notes - Lecture 2: Neural Coding, Visual Perception, Prosopagnosia
Document Summary
Introspection: how did introspection count the number of sensations? and added up the answers. You can only access the output of the mind with introspection. Spatial vs temporal resolution: distinction between spatial resolution and temporal resolution. Different ways to evaluate different neurological measures of the mind. Different types of neural coding: 3 different types of coding? specificity coding: 1 specific stimulus = 1 specific neuron fire. Visual perception: insight from specific disorders: visual agnosia loss of ability to recognize objects. Preserved ability to navigate and reach: he knows exactly where things are, e. g the guy could still play the guitar and identify forks and spoons with touching. Bilateral (both left and right) damage to occipital/temporal lobes: prosopagnosia (specific to face recognition) Deficit in navigating and reaching around the environment inability to navigate and reach: couldn(cid:495)t tell where the objects were when he tried to reach for. He couldn(cid:495)t see two objects at the same time (cid:523)one had to be more.
