Genetic and environmental explanations of juvenile violence in advantaged and disadvantaged environments

Article Abstract:

A study was conducted to confirm the validity of the behavioral genetic theory assertion that IQ and environmental factors influence violent juvenile delinquency in different ways within advantaged and disadvantaged economic backgrounds. Respondents were 388 white juvenile delinquents who were divided into three groups: the environmentally disadvantaged, the disadvantaged and advantaged, and the advantaged. Findings revealed that juvenile violence among the environmentally disadvantaged was mainly caused by love deprivation, while among the advantaged, it resulted from imbalance in intelligence levels.

Why do aggressive movies make people aggressive? An attempt to explain short-term effects of the depiction of violence on the observer

Article Abstract:

A study exploring the phenomenon of increased aggression in people viewing an aggressive film was conducted using 105 German students. Results are explained using the motivation theory of aggression. People become more aggressive after an aggressive movie because of a change in the expectancy-value-cognitions thatfavor aggression. There are some inconsistencies in the results such as the zero-effects for certain values in the instrument used.

Parental attachment, drug use, facultative sexual strategies

Article Abstract:

Parental attachment has a strong statistical relationship with sexual promiscuity and drug abuse. A survey has been conducted on 480 college students to verify the traditional claim that poor parental attachment is a crucial factor behind drug abuse and sexual promiscuity. Factors like religiosity, masculinity and feminity, sex, age and physical appearances were also studied to test their effect on the two variables.
