Document Summary
Cognitive psychology chapter 4 paying attention. Shadowing: a task in which research participants are required to repeat back a verbal input, word for word, as they hear it. Attended channel: in selective attention experiments, research participants are exposed to simultaneous inputs and instructed to ignore all of these except one the attended channel is the input to which the participants are instructed to pay attention. Unattended channel: a stimulus (or group of stimuli) that a person is not trying to perceive ordinarily, little information is understood or remembered from the unattended channel. If asked, after a minute or so, to report on what was said on the unattended channel, they cannot. Participants seem to be able to remember the unattended channel"s physical content (eg. voice, musical instrument, silence, male or female voice, etc. ) We are also able to promote the processing of desired stimuli.
