In a study, parents were asked to rate each television program that their children watched. The programs were rated for violent content on a scale of one to five, with “one” indicating no violence and “five” indicating a great deal. The number of times their children were disciplined in school was also recorded. Children who watched programs with an average violence rating of three or higher were 50 percent more likely to have been disciplined than other children.
Each of the following, if true, helps to explain the statistical relationship described above EXCEPT:The stimulus gives only a correlation: children who watched more violent TV were more likely to be disciplined in school. So the correct answer is the choice that does
not help explain that correlation. A choice can help either by saying violent TV contributes to school misbehavior, or by saying some third factor makes both things more likely.
(A) Children who are excited by violent action programs on television tend to become bored with schoolwork and to express their boredom in an unacceptable fashion.
This helps explain the correlation. It gives a causal path from violent programs to unacceptable behavior in school.
(B) When parents watch violent programs on television with their children, those children become more likely to regard antisocial behavior as legitimate.
This also helps explain the correlation. If violent TV makes children more accepting of antisocial behavior, that could make school discipline more likely.
(C) Parents who rated their children’s television viewing low on violence had become desensitized to the violence on television by watching too much of it.
This does not help explain the correlation. If these parents underrate violent content, then some children placed in the “low violence” group may actually be watching more violent programs than reported. That would blur the difference between the groups, not explain why the higher-violence group had more discipline problems.
(D) Children learn from violent programs on television to disrespect society’s prohibitions of violence and, as a result, are more likely than other children to disrespect the school disciplinary codes.
This helps explain the correlation. It gives a direct reason why watching violent TV could lead to more discipline in school.
(E) Parents who do not allow their children to watch programs with a high level of violence are more likely than other parents to be careful about other aspects of their children’s behavior.
This helps explain the correlation through a third factor. More careful parents may both restrict violent TV and manage their children’s behavior better, leading to fewer school discipline problems.
Answer: (C)
