Executive control Flashcards
Harlow 1848
Phineas gage - frontal lobe damage implicated in high level control of context-dependent actions and disposition
Milner & Petrides 1984
individuals with frontal resections make perseveration errors in the WCST
they have problems with recency judgements, planning and self-generated action
linked to organising memories flexibly
Eslinger & Damasion 1985
ventromedial prefrontal damage patients show preserved cognitive abilities in the lab but have impaired knowledge of appropriate social conduct in real life
Lhermitte et al., 1986
imitation and utilisation behaviour is uncontrolled in patients with frontal lobe lesions resulting in reflexive action bound to the primary response elicited by a stimulus to high accuracy
(Mesulam, 1986, 2002)
difficult to characterise a unitary frontal lobe syndrome as symptoms associated with lesions are vast and varied and depend on the nature of the lesion and individual
experimental tasks used to study executive functions
a. Wisconsin Card-Sorting Task (Grent & Berg, 1948)
b. Verbal fluency (FAS) (Benton & Hamsher 1976)
c. Tower of London Task (Shallice, 1982)
d. Multiple-Errand Task (Burgess & Shallice, 1991)
e. Stroop Colour-naming Task (Stroop, 1935)
f. Task switching (Jersild 1927; Rogers and Monsell, 1995)
g. Flanker Task (Eriksen & Eriksen, 1974)
h. Stop-signal task (Logan & Cowan, 1984)
psychological theories of executive control funcitons
Supervisory Attention System (Norman & Shallice, 1980)
Cognitive-neural Model (Miller & Cohen, 2001)
Contemporary Models (Braem et al., 2019)
Norman & Shallice 1980
supervisory attention system
automatic
contention scheduling
deliberate conscious control
miller & cohen 2001
cognitive neural model
temporary context-based networks of association configured to guide behaviour
top-down biasing signals between sensory input and behavioural output
Braem et al 2019
contemporary learning perspective models
mutual influences between control functions and simpler learning related functions
Neuropsychological studies
The case of Phineas Gage (Harlow, 1848, 1868): After his freak accident, the
mild-tempered railway worker had preserved perception, memory, language; but
his temperament and personality changed.
b. Brenda Milner (1963 onward) showed that individuals with frontal resections
made perseveration errors in the WCST, had problems with recency
judgements, planning, and self-generated action (Milner and Petrides, 1984).
c. Individuals with ventromedial prefrontal damage have preserved cognitive
abilities in the lab but lead disastrous lives in the real world (Eslinger and
Damasio, 1985).
d. Imitation and utilisation behaviour (Lhermitte et al., 1986): individuals with frontal
lesions become bound to the physical and social environment.
e. Symptoms after frontal lesions can be highly variable and may depend on
factors related to location and time course of lesion as well as the individual’s
age and personality at the time of the lesion (Mesulam, 1986; 2002).
