Flashcards in Executive functions mediated by (pre)frontal lobes Deck (15):
1

What do executive subfunctions look at?

Much wider range of cognitive activities - concrete, short duration, to complex and long running.

2

What are some of the common functions of the range of cognitive activities (concrete, short duration, to complex and long running)?

-Working memory
-Strategy formation
-Reasoning
-Planning
-Response regulation
-Emotional regulation
-Social judgment
-Decision making

3

Recognition of

important information

4

Discrimination of

primary from secondary or relevant from irrelevant stimuli

5

Plan development including

appropriate sequence of steps

6

Initiation of

action/response

7

Sustaining

responses

8

Discontinuation of

action/response

9

Evaluation of

outcome of action/response

10

Modification of

strategy with changes in circumstances or based on response feedback

11

Common theme to all executive functions mediated by (pre)frontal lobes:

consolidation and retrieval on new info; a way of directing cognitive abilities toward a specific goal; goals are always changing in relation to context/environment; executive functioning - what goal do I need and how do I get there?

12

Anterior and posterior systems:

-Anterior is DLPFC; chooses target like lecture rather than clicking keyboard
-Posterior is important in working memory as well; involved in spatial information; where multimodal sensory association area is located - receives info from all sensory areas. Highest level of perception -> directing part of system so engaging and disengaging certain parts

13

Working memory alters the way...

cortical processing occurs

14

Superior:

spatial working memory (WMS spatial test)

15

Inferior

object working memory (symbol search on WAIS)
