ICONIC AND ECHOIC MEMORY Kenneth J. Malmberg, Ph. D
The Modal Model - Atkinson & Shiffrin (1968) Structures: Invariant properties of memory 1. Sensory Memory: holds all incoming information for seconds or fractions of seconds 2. Short-term Memory (STM): limited capacity, holds information for 15 -30 seconds 3. Long-term Memory (LTM): holds large amount of information perhaps permanently
Sensory Memory
Sperling’s Work on Sensory Memory Sperling (1960) Briefly flash arrays of letters Follow with a mask Cue memory with a tone IV: Vary the number of letters DV: number of letters reported
Sperling’s Work: Critical Manipulation Full Report: Report all the Items Partial Report: Report only items from a specific row
Sperling’s Work: Findings Full Report: Report all the Items Partial Report: Report only items from a specific row After a delay subjects report approximately the same number letters in both tasks.
