Quantifying aggression: Effects of identity of stimulus

A test for children's insight into relations between behaviour and aggressive emotion showed that kindergarten children showed an increase in ratings of emotion corresponding to an increase in aggressive behaviour (positive relation), and that an increase in ratings of emotions corresponding to a decrease in aggression-related behaviour (negative relation) was shown by seven- and nine-year-old children. Cognition of relations between aggressive emotion and behaviour seemed to be developed earlier than cognition of relations between intention and behaviour as observed in a previous study. Results from the test also indicated that the magnitude of emotion ratings differed in identity (same stimulus person) and non-identity (differed stimulus persons) stimulus conditions.
