Working memory model

Working memory model - Baddeley and Hitch

• Focuses on workings of short term memory
• Important for reasoning learning and comprehension

4 parts :

• Articulatory-Phonological loop: Inner voice process language to convert to a phonological state - Inner ear holds auditory speech information & the order of which it as heard
• Central executive: Manages attention and controls information from the 2 slaves stores
• Visuospatial-spatial sketchpad: temporarily retains visual and spatial information
• Episodic buffer: Facilitates communication between the entrar executive and LTM

Strengths:

• provides explanation for parallel processing
• Based on evidence from a laboratory experiment so confounding variables are controlled (results can be replicated)

Weakness:

• unclear what central executive is too vague
• Low eco-logical validity
