The Codevelopment of Sympathy and Overt Aggression From Middle Childhood to Early Adolescence
We assessed the extent to which feelings of sympathy and aggressive behaviors codeveloped from 6 to 12 years of age in a representative sample of Swiss children (N = 1,273). Caregivers and teachers reported children's sympathy and overt aggression in 3-year intervals. Second-order latent curve models indicated general mean-level declines in sympathy and overt aggression over time, although the decline in sympathy was relatively small. Importantly, both trajectories were characterized by significant interindividual variability.
