P 355, Miyamoto, Winter '09 2 Outline • Summary re Short-Term Memory (STM) • Introduction to the Working Memory (WM) Model o Phonological Loop (PL) o Visuospatial Sketchpad (VSP) o Central Executive (CE) • Phonological Loop – What is it? How do we know it exists? Next: Three Important Characteristics of STM

P 355, Miyamoto, Winter '09 3 Three Important Characteristics of STM 1. STM has limited capacity, and . .. 2. Active maintenance is needed to retain information in STM. 3. Information in STM is high accessible. All of these characteristics are assumed in the working memory (WM) model. NEXT: Why do we need a more complex memory model, called the “working memory” model? What is the general structure of the working memory model? Next: Working Memory (WM) – General Idea

P 355, Miyamoto, Winter '09 4 Working Memory (WM) – General Idea • Multiple components of STM. • Executive control that manipulates information in STM and selects strategies for manipulating information in STM. Next: Main Differences Between the STM & WM Models

P 355, Miyamoto, Winter '09 5 Main Differences Between the STM and WM Models Short-Term Memory (STM) • STM is a single component • Main theoretical issue: How long and how much information can be stored in STM? Working Memory (WM) • WM consists of multiple parts • Main theoretical issue: How is information represented and manipulated in WM? • The issue of the duration and quantity of information storage is still important for WM, but how WM manipulates information is more important. Next: PL, VSP & CE – Diagram & Intro

P 355, Miyamoto, Winter '09 6 Baddeley-Hitch Working Memory (WM) Model 1. Phonological Loop (PL) o Short-term storage o Rehearsal o Manipulation of verbal information 2. Visuospatial Sketch Pad (VSP) o Storage & manipulation of visual images and spatial information. 3. Central Executive o Directs activity within the PL or VSP. o Coordinates activity between PL or VSP, and between these components and long-term memory (LTM). Next: PL had 2 Components

P 355, Miyamoto, Winter '09 7 Phonological Loop (PL) Two Subcomponents: Articulatory rehearsal creates the sound pattern of words. o E.g., If I show you the printed words, “cat”, “clock”, “creek,” and ask you to remember them (retain in the PL), you translate the written forms into sound patterns (spoken form of “cat”, “clock”, “creek”). Phonological store
