working memory model

why was wmm devloped

to show that STM is not a unitary store but rather an active processor for different types of information.

central executive

supervisory component that monitors incoming data

involved in ability to plan, reason and make decisions

limited capacity and modality free coding

phonological loop

deals with auditory information-inner ear

phonological store=stores words you hear

articulatory process=active rehearsal allows rehearsal to keep them in your WM

limited capacity-2 sec, coding is acoustic

visual spatial sketchpad

stores visual and spatial info-inner eye

visual cache=temporary stores visual data

inner scribe=records arrangements of object in visual field

limited capacity and visual coding

episodic buffer

temporary store for info integrating visual, spatial and verbal info processed by other sub stores

limited capacity-4 chunks, coding-modality free

dual task performance

doing two visual tasks at the same time
