Document Summary
Attention: the ability to focus on specific stimuli/locations. Selective attention is focusing your attention on a particular object/event while ignoring other. Divided attention: paying attention to more than one thing at a time. Attentional capture: a rapid shifting of attention usually caused by a stimulus such as a loud noise, bright light, or sudden movement. Visual scanning: movement of the eyes from one location/object to another. In 1950s, a new approach to studying cognition was becoming popular: information processing approach. Attention became an important topic of research during this time period. Broadbent proposed his filter model of attention: proposes that a filter that lets attended stimuli through and blocks some/all of the other unattended stimuli. Dichotic listening: presenting one message to the left ear and a different one to the right ear. The dichotic listening experiment showed that subjects weren"t aware of the information presented to the unattended ear.
