Document Summary
Selective attention: process by which one input is attended to and the rest are tuned out. Necessary because we don"t have the capacity to pay attention to everything in our environment. Attended channel: the channel the individual was told to listen to in the dichotic listening study. Unattended channel: the channel the individual was told to ignore in the dichotic listening study. Donald broadbent: thought of the brain as a processing system with a limited capacity and sought to map out the steps that went into creating memories from raw sensory data; developed the broadbent filter model of selective. Inputs enter a sensory buffer; one of these inputs is then selected and filtered based on physical characteristics of the input. If it doesn"t go through, it re ains brief y but then quick y decays and disappears. Cocktail party effect: happens when information of personal importance from previously unattended channels catches our attention.
