PSYB51H3 Lecture Notes - Lecture 7: Electroencephalography, Fusiform Face Area, Inattentional Blindness
Document Summary
Attention: any of the very large set of selective processes in the brain. Motor accuracy: brain activity, eye movements: overt shifts of attention but not covert shifts of attention. What"s the difference between stimulus-driven/ peripheral and voluntary/symbolic: partially independent neural structures, stimulus onset asynchrony (soa): the time between the onset of one stimulus and the onset of another. Different time courses of soas; slower effects for voluntary cues. Inhibition of return (ior: overt shifts of attention: a shift of attention accompanied by corresponding movements of the eyes, covert shifts of attention: a shift of attention in the absence of corresponding movements of the eyes. Natural biases: perceptual biases: asymmetries in perception between the left and right side of a stimulus. Vary with task, e. g. listening to speech: line bisection task, grating scales: Electroencephalography: leftward bias associated w/greater negativity over the right brain >280ms: space-based cueing of attention, feature-based cueing of attention: attention is guided based on non-spatial information about features.
