Because jesse’s teacher believes that he is intelligent, she challenges him with extra assignments and generally encourages his curiosity. at the end of the school year, jesse performs better on the school’s achievement test than any other student. jesse’s enhanced performance is likely due to the .recency effect c. self-serving bias b. expectancy effect d. judgment bias

B). Expectancy effect.

Explanation:

Jesse's enhanced performance is likely due to the expectancy effect which evokes a reaction from him when his teacher expects a given result and thus, Jesse unconsciously affects the results positively. The teacher's belief and confidence instills hope and certainty in him convincingly. This belief eventually encourages him to accept the teacher's challenge and compels him to perform(to maintain the teacher's belief in him) at his best and elicit an unexpected outcome. Thus, the answer is 'expectancy effect'.
