frontal lobe
What is executive function?
Inhibition
planning and organisation
cognitive flexibility
concept formation, reasoning, problem solving
Where abouts does executive functioning occur?
Dorsolateral PFC: cognitive
- problem solving, organisation, cognitive flexibility, emotional range
Orbitofrontal PFC (eye): behavioural
- disinhibition, impulsivity, distractibility, emotional lability
Ventromedial PFC: emotional
- apathy, emotional blunting, impaired decision making
What are the problems associated with neuropsychological assessment of executive functioning?
- the structure of the assessment leaves little room for inappropriate behaviour
- need to focus on the qualitative assessment findings
- need to take into account informant reports of day-to-day functioning
- involves non-executive skills
- ecological validity?
Assessment of inhibition
- ability to withhold automatic responding and respond in a novel manner
–> via the stroop test
–> via Hayling’s sentence completion test
assessment of planning and organisation
- identification of steps and elements needed to achieve a goal.
–> clock drawing
–> rey complex figure test
–> key search test
assessment of cognitive flexibility
- swithc between different ways of responding
–> trail making test
–> clock drawing (they might juts keep writing numbers)
–> sorting task
assessment of concept formation, reasoning and problem solving
- devleoping concepts and strategies to solve complex problems
–> sorting task
–> spatial anticipation task (circles)
–> verbal fluency (FAS animals) (for most, semantic category is easier than letter)
–> reasoning based on verbal information
–> tower task
What are the conditions effecting exec function
TBI- frontal lobes are particularly vulnerable
Frontotemporal dementia
Schizophrenia
