- Working memory model
- Outline
- Baddely & Hitch (1974) - proves there is more than one component to STM
- Central executive --> control system, monitors, coordinates and directs the operation of the slave systems (visio-spatal, eposodic, phonological), allocates attention, no storage capacity
- Visio-spatal scratch pad --> works as 'inner eye' - responsible for visual slatal coding (writing pad for remembering data), information only temporarily stored here, Logue (1995) suggested it could be divided into a visual cache (store) and inner scribe
- Eposodic buffer --> general store - up to 18 secs (STM), limited capacity, intergrated information from slave systems + LTM
- Phonological loop --> 2 parts: articulatory control system (rehursal of sounds - inner voice) responsible for acoustic encoding and phonological store (holds the words you hear - inner ear), limited capacity
- Evaluation
- Positives
- ehursal not the only means of transferring information - only a component within articulatory loop. also a extrememly influential model
- PET brain scans show different parts of the brain are used whilst undertaking verbal and visual tasks - correspond with components of WMM.
- explains STM in terms of temporary storage and active processing - unlike MSM
- ttempts to explain how memory functions - phonological loop helps us understand complex text and learn vocab e.g. not operative in some with dyslexia.
- Brain damaged patient KF could remember visual but not verbal stimuli --> STM must be at least 2 systems --> disproves MSM
- Negatives
- Positives
