Cognitive Psych 1/6/11 9:24 AM February 3, 2011 Lecture 7: Short-Term Working Memory, Part I Objectives: (1.) To understand how double dissociations support the distinction between STM and LTM, and the variables that affect each type of memory. (2.) To understand the factors that affect STM capacity (e.g., recoding). (3.) To understand the theoretical debate about how information is forgotten from STM (e.g., decay vs. interference) and the evidence bearing on this debate. Notes: - modal model or “standard theory” (Atkinson & Shiffrin, 1981): sensory memory (iconic, echoic) ! STM "! LTM sensory memory short-term memory (STM) (see past lecture) o Attention/consciousness o Limited capacity – has control processes # Rehearsal # Operators # Encoding # Retrieval - Short-term memory (STM) Alternative nomenclature STM vs. Long-term memory (LTM) o Is there a difference? o Free recall – Given list of words, recall them back in any order # Highest accuracy for first and last words, least accuracy
