This study examined the effects of age and aggressive status on children's understanding and use of excuses. Younger (3rd-5th grade) and older (6th-8th grade) aggressive and nonaggressive African American boys were first instructed to imagine that they failed to fulfill a social obligation. The cause of the transgression was presented as controllable (e.g., choosing to do something else), and children indicated whether they would reveal that cause or make up an excuse. Next, 4 causes of the same transgression were manipulated to be either controllable or uncontrollable. Children inferred that they would be held more responsible for controllable causes of social misconduct, that these causes would elicit more anger, and that they would be more likely to withhold these causes (i.e., make up an excuse). The linkages between perceived responsibility, anticipated anger, and excuse giving were stronger among older than younger boys and among nonaggressive than aggressive boys.
