psych memory 2
| Question | Answer |
|---|---|
| who coined the modal model | Atkinson & Shiffrin |
| evidence of STM | limited duration of info - 15-20 s (Brown-Peterson paradigm), limited storage capacity - 7 chunks (Miller, 1956), categorical coding (Conrad, 1964) |
| wright et al. 1985 study | learning phase: presentation of 4 complex stimuli for 1 or 2 seconds .. to pigeons, monkeys, humans. retrieval phase: recognition of pictures. Immediate recall, intermedtiate delay and long delay |
| wright et al. 1985 study interpretation of results | STM-LTM distinction in different species. |
| Classical view of STM (Atkinson & Shiffrin modal model) | sensory memories - STM (control processes, repetition, chunking) - LTM. |
| Working memory - Baddeley's 1986 model components | Visuospatial sketchpad, central executive, phonological loop |
| evidence of phonological loop | -effect of phonological similarity (Conrad & Hull, 1964) - effect of unattended speech (Salamé & Baddeley, 1987) - word-lenght effect (Baddeley 1975) -Effect of articulatory supression (Hanley and Broadbent (1987) |
| what is visuo spatial sketchpad | system employed in the creation and use of images .. comprised of visual component for processing visual info, and spatial component for processing info of spatial locations |
| structure of visuospatial sketchpad | visual cache: passive store inner scribe: an active spatial rehearsal process |
| what is central executive | supervision mechanism that directs attention and coordinates the activities of the other components |
| SAS model (Norman and Shallice, 1986) | role of attention in the control of actions. automatic vs willed (conscious) |
| what brain region is the SAS associated with | frontal lobe |
| late addition to Baddeleys working memory model | episodic buffer |
| what is episodic buffer | storage subsystem that can hold about 4 chunks of info in a multi-dimensional code. acts as a llink between the different subsystems of WM |
| Functions of phonological loop | vocab acquisition, long term phonological learning, language comprehension |
| functions of visuospatial sketchpad | production and use of mental imagery, geographical orientation, planning spatial tasks |
| functions of central executive | reading comprehension |
