Note that PsycInfo is not like Google. It does not default to searching for all of the terms you have listed, but treats words without special connectors (Boolean operators) as phrases—like putting quotation marks around it on Google. So, in order to get the equivalent of the Google search that television aggression children would provide, you have to type in television AND aggression AND children in PsycInfo.
