Final answer:
Lars is more likely to recall his high school graduation when he is depressed, due to mood-congruent memory, where people remember information consistent with their current mood. The correct answer is option: b. depressed.
Step-by-step explanation:
Lars is especially likely to recall his high school graduation when he is depressed. According to the mood-congruent memory theory, people tend to remember information that is consistent with their current mood or affective state. When Lars is feeling depressed, he is more likely to recall other times when he felt similar emotions, including his high school graduation if he was feeling depressed at the time.
This phenomenon can be explained by considering how emotions impact our cognitive processes. When we experience a particular emotion, it can cue memories that are associated with that emotional state. For example, when feeling elated after a sports victory, one might remember other moments of triumph and happiness. Conversely, when experiencing fear prior to giving a speech, one might recall past experiences where they felt anxious or scared. These examples shed light on how our moods can influence the types of memories that come to mind.
