June is interested in ascertaining relationships between violent television viewing in children

and their aggressive responses in a laboratory setting.

To maximize her treatment effect, she
exposes children in the violent television viewing group to 20 minutes of spliced together,
uninterrupted violence. After the procedures are conducted, June documents that the children
who watched the violent programming were 3 times more likely to exhibit aggression than
children in the other groups. What possible concern might most realistically arise regarding
this study?
A) The children in the violent television viewing group may have become addicted to
violent television and may want to watch such television programming when they go
home.
B) The study has poor internal validity because June did not get strong results.
C) The study may have low external validity because the manipulation was not realistic of
what one would typically encounter in the real world.
D) The study results should not be trusted because of the correlational design.
