PSYB57H3 Chapter Notes -Feature Integration Theory, Insular Cortex, Basal Ganglia
Document Summary
Psyb57 chapter 3: attention: attention: at a given moment, enhances some info and inhibits other info. The enhancement allows us to select some information for further processing, and the inhibition of other info from receiving further processing. Driven & controlled by top-down processing change in dynamic manner! (ex, hungry notice fruit on table, if full attention glide over it) An efficient way to extract crucial info from flood of info (ex, scanning through textbook) A competitive system in which tuning into one thing inhibition of. Does not engage in only one area of the brain! Implemented in wide, distributed circuit in which diff brain regions contribute. Involves selection that can occur early, late or at both times & driven by our will/strength of stimuli in the environment + on the basis of space/objects/time: failures of selection in space vs failures of selection in time.
