Document Summary
Section 1: introduction to attention (message in bold) among the most important, cognitive abilities is the ability to select a signal from noise. You do this by focusing on certain cues such a type style. When we focus our attention on certain stimuli, the message in other stimuli is not clearly identified. Attention can be switched between ears at random/periodic intervals flexible control over attention. Semantic content sent to attended ear is well remembered semantic content is vague some info is processed in unattended ear. Ex. listeners can report pitch and tone from unattended ear. Results: items selected for attention are better perceived and later remembered than items not attended. Ex. always put keys on front desk when you return home so in the morning when you are rushing out the door you direct your attention to that location rather than searching the entire house. Allows experimenter to measure shifts in attention in the absence of eye movements.
