Attribution of intentionality as a function of age,outcome quality and affect for the actor

Studied the degree to which 40 children (half boys, half girls) in each of three age groups of 5–6, 7–8 and 9–10 years would be affected by the qualities of the actors and the outcomes in perceiving certain acts as either intentional or accidental. Each subject was randomly assigned to either the liked-actor or the disliked-actor conditions and was then administered both the good- and the bad-outcome stories, represented by pictures. Upon listening to each story in which the motivation of the actor was left ambiguous, the subject was asked to specify whether the act was meant to be done or not. The results indicate that in general all children showed a significant tendency to interpret a bad outcome caused by a liked actor as being accidental and that caused by a disliked actor as being intentional; conversely, when the outcome was good, the behavior of the disliked actor was interpreted as being accidental and that of the liked one as being intentional. Although there were no age differences within the experimental conditions, differences were observed between the conditions for different age groups. In general a developmental lag was revealed in the attributive behavior with respect to the disliked-actor condition. One important implication of the study is that children by 5 years of age seem to have learned the evaluative difference between causing something intentionally or accidentally, depending on the outcome quality. The results were interpreted in terms of Heider's ‘balance principles’ which were suggested to serve as a vehicle for making causal inferences.
