consolidation theory

Answer 28

memories undergo change since acquiring them. Gradual strengthening of cortico-cortical connections.

Question 29

heuristics

Answer 29

process in decision making that gives us acceptable solution but not perfect.

dorsal stream

Answer 34

vision-for-action, body centred coding, short lived representation

Question 35

ebbinghaus illusion

Answer 35

both centre cirles are same size but one in top looks larger due to distance.
