Final answer:
The exact findings of Paquette and Underwood's (1999) study are not specified, but related research shows a link between media violence and increased aggression in children.
Step-by-step explanation:
The study conducted by Paquette and Underwood (1999) isn't detailed in the information provided. However, related research in the field, such as that by Anderson and Bushman (2001), indicates a link between exposure to violent media and an increase in aggression in children. This aligns with findings by other scholars like Gentile, Mathieson, and Crick (2011) who noted that exposure to media violence is associated with increased physical as well as relational aggression. Although there is a debate on the impact of media socialization, and some studies could not find a direct correlation between viewing violence and committing criminal violence (Savage 2003), the prevailing evidence suggests a causal link between violent media and increased aggressive behavior.
