Working Memory Model Baddley and Hitch More complex than the multi-store memory model Working memory replaced short term memory Not a unitary store Different systems for different information Explanation of how memory functions rather than the structure Central executive, phonological loop, Visio-spatial sketchpad Central executive: drives the whole system, allocates data to the slave systems. It also deals with cognitive tasks such as mental arithmetic and problem solving Phonological loop: is the inner voice. Temporary storage system with limited capacity; is responsible for holding spoken and written material. Phonological store (inner ear): holds information in speech based form for 1-2 seconds. Articulatory control process (inner voice): linked to speech production, used to rehearse and store verbal information from phonological store. Visuo-Spatial Sketchpad: Stores and processes information in a visual or spatial form. Episodic buffer: temporarily stores information and links it with LTM. Limited capacity. Primary acoustic store: holds recently heard speech or sound Central executive Phonological Loop Visuo-Spatial Sketchpad Episodic Buffer Information Any Sound Images/Spaces Any Function Control other components/ Synthesise information/planning/problem solving. Stores and repeats sounds Manipulates images Integrates information from different sources Testing Tasks Problem solving/generating random information Verbal reasoning Visual imagery Evidence: For working memory model Baddley and Hitch: -PPs asked to complete a reasoning task whilst reading aloud a list of 6 digits.. -They found PPS made few errors on either task -If we do two tasks simultaneously that are both visual we will perform worse than if the two tasks were different because they are fighting for the same component. -Lacked ecological validity
