The average level of multisensory facilitation to endogenously driven motor responses does not change gradually with age nor is it related to intelligence or reading accuracy. In general, multisensory integration remains immature until 10-11 years of age and lies within the predicted confines of race-models.

Experimenters observed the number of sport-team-identified fans who contributed money to charity workers before and after 6 football games. Charity workers were identified as supporters of 1 of the 2 teams competing, or of neither team. Consistent with predictions, more fans contributed to in-group than to out-group-supporting charity workers. In addition, charity workers identified with either team received a higher frequency of contributions from fans of both teams together after the game relative to before; this pattern was reversed among charity workers not identified with a team. This unexpected finding suggests an increased salience of a general sport-fan identification after the game relative to before. Finally, fans of winning teams in particular contributed more to any charity worker (i.e., collapsed across in-group, out-group, and neutral supporters) after the game than before, but this pattern was reversed among fans of losing teams. This final finding is discussed with reference to both self-categorization theory and the literature on mood and prosocial behavior.
