Sensory Stores
• Sensory Store: holds information for a brief amount of time; there is a different store for each sense • Iconic (图标的）Memory: The visual sensory store; information begins to decay after about 250 ms.; we only need/use the 1st 50 ms. • Sperling (1960); gave Ss 3X4 matrix of letters; whole report: report all the letters; Ss perceive all, report part, why? • partial report: report only row indicated by tone, better result, why, yet 1 minute later similar to whole • Echoic (回声的）Memory: The auditory sensory store; lasts about 4 seconds。 • Why longer than iconic memory? • The sensory stores hold the literal, unanalyzed information
long enough for further analysis.
