Cignitive Control And Social Cognition Flashcards
What did schneider and Schmidt run 1977 do?
Controlled processes have limited capacity, require attention
Automatic persona have no capacity limitations, no attention and can modify once learnt
What is automaticity
Salient stimuli can attract attention, memories can be automatically activated and some behaviours are automatic
Befenical to free up out attention all capacities
But need to control ourselves and overcome automatic impulses e.g. Beer… for appropriate behaviour
What did shallice and burgess 1992
Automatic behaviour isn’t enough for automatic performance.
Incorrect response is liable by production of routine patterns or no routine procedure to produce automatic reaspinse
More basic tasks e.g. Strip takss, action inhibition, wm tasks… more complex tasks such as planning/reasoning tasks
What does the prefrontal cortex
Large body of research links to cognitive mechanisms of PFC
THIS is enlarged in humans, last area to mature
What happens with PFC damage?
Have cognitive control development behaviour problems / dysexecutive syndrome
Confabulation (weird belief/memory errors
What did damasio et al 1985 do?
Patient with orbiofrkntsl cortex damage thought he was a pirate after brain damage
What did baddley and hitch 1973 do
Central executive controls slave systems
What did Norman and shallice 1989 do
Perceptual inputs trigger schemes learned sequences of behaviours
Competing schemas mutually inhibit each other
If situation requires flexible behaviour, SAD is invoked and biases schemas
What is the SAS model?
Linked with selective attention. Emphasises role of cognitive processes in top-down over automatics processes
Links SAS with frontal lobe and dysexecutive syndrome
Baddeley 1993 suggested SAS corresponds to wo central executive
What does activity in lateral PFC show
Involved with maintaining WM content
What did duncan 2010 do
Several PFC REGOINS are correlated with fluid intelligence (abstract thinking, problem solving
Is wm and sas domain general or specific
Domain general, not specified to type of info
Control is poorly specified
What did cohen et al 2000 do
Two main components are needed for top down control
Detection of need to control (LPFC) and control implementation (ACC)
Is PFC CONTROL top down or bottom up
Top-down. Some Argue it influences posterior regoins by amplifying cetrainnresponses
What is gazzaley et al 2005
Attention seems to be both amplify selected and inhibit ignored information activation in right PPA AND FFA
