Answer:
Social psychologists would say that, in reporting the students, Joey engaged in altruistic punishment.
Explanation:
If someone chooses to punish someone else even though such an action will not only bring no benefit to himself but may even bring harm, he is engaging in altruistic punishment. That is the case with Joey in the situation described in the passage. Joey is aware that what the two other kids did is wrong. He also knows that, by reporting them, he will suffer consequences (being teased). Still, he altruistically chooses to sacrifice his own peace to have the cheaters pay for their mistake.
