Jeremy loses his former interest in doing arithmetic after his teacher promises him $1 for each problem he solves correctly. Which theory best explains Jeremy's loss of interest in arithmetic?

self-perception theory

Step-by-step explanation:

While Festinger's self-perception theory assumes the existence of an internal impetus to maintain consistency between different perceptions, on the contrary, self-perception theory wants to interpret the attitude of a subject. by deducing from the subject's own behavior without having to assume a motivation to minimize the conflict between perceptions.

In this case, he does arithmeti everyday with $2 for each problem he solves correctly, I conclude that he like doing that. But now, only $1 for each problem solving so no more motivation, he losses his interest.
