is executive function conscious or subconscious?
conscious, goal-directed thought and action.
are elective functions single cognitive processes?
it is unlikely as factor analysis on batteries of EF tests show multiple factors, though they are correlated.
can we differentiate EFs?
behaviourally: frontal lobe damage affects different EF abilities differently.
biologically: different areas of the frontal lobe are involved in different tasks.
what are the three factors that emerge from EF battery tasks?
inhibiting control, updating/working memory, shifting
what is inhibitory control?
simple vs complex inhibition. different cognitive demands for different tasks with additional WM demands, only 50% of 5-6 year olds pass.
what is simple vs complex inhibition?
simple inhibition is shown in infancy (e.g. delaying eating a treat) complex inhibition requires holding a rule in mind or producing an alternative response, may also involve conflict.
