Understanding context, the rules necessary to achieve goals - complex rules of social world
Planning for future, imagining future scenarios = use to find out goals and behaviours

Question 5

describe executive functions= changing strategies

Answer 5

Keep tryinhg same thing over and over again

Question 6

describe executive functions= working memory

Answer 6

Hold things in mind so can do tehse complex behaviours - important for executive fucntions

Question 7

describe frontal lobe

Answer 7

Involved in action
Rostral = abstract aspects of action
Intermediate = sma, organizing and planning moeevmnt
Caudal = specific action required to achieve goals abstract goal

Question 8

describe prefrontal cortex

Answer 8

Central to executive fucntion
Rostral, lots on medial surface, lateral and medial parts do different things

Question 9

dorsal lateral regions pfc = interconnected with

Answer 9

Pre motor and sensory association cortex
Parietal lobe and higher order association regions, motor regions = sma

Question 10

dorsal lateral regions pfc = associated with

Answer 10

asosciated with cold executive fucntions = like solving a multi step math problem
Key role in working memeory
Not as social or emotional

Question 11

Ventral medial regions pfc = interconnected with

Answer 11

Temporal lobe and sub cortical limbic structures

Question 12
