Abstract:  Examined the relationships between aggression, the viewing and enjoyment of TV violence, and the personality traits of extraversion, neuroticism, and psychoticism. Data obtained by questionnaire from 386 sibling dyads (aged 11-16 yrs) in Northern Ireland failed to support the theory of a causal effect of the amount of viewing of TV violence on aggression. The theory, however, can be reformulated in terms of a genotype-environment correlation and interaction model. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
