a familiar context or setting can help retrieve or activate new memories

90
Q

mood-congruent memory

A

tendency to recall experiences that are consistent with one’s current good or bad mood

91

Q

forgetting curve

A

a graphic depiction of the amount of forgetting over time after learning has taken place

A

the backward-acting disruptive effect of newer learning on the recall of old information

the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories

100
Q

misinformation effect

A

occurs when a memory has been corrupted by misleading information

101
