When a Lot of Knowledge Is a Dangerous Thing The Debilitating Effects of Plan Complexity on Verbal Fluency

Three experiments examined the relationships among plan complexity, access to planned actions, and verbal fluency while pursuing a persuasion goal. Consistent with theoretical expectations, complex planners were less fluent than less complex planners under high access conditions. Persons whose access was raised were less fluent than those whose access was not raised. A second experiment showed that reduced fluency was not induced by lowering of self-confidence. The third experiment replicated the findings of the second experiment and demonstrated that the questioning procedure used to raise access in the first two experiments produced increases in plan complexity as suggested by theory. These findings are discussed in terms of their implications for the study of strategic communication.     

The Interpretation of Anaphoric Noun Phrases Time Course, and Effects of Overspecificity

Two experiments investigated the interpretation of anaphoric noun phrases, and in particular those thatcould only be linked to their antecedents via knowledge-based inferences. The first experiment showed that much of the inferential processing was carried out as the anaphoric noun phrase was read, although there was some indication that inferential processing continued to the end of the clause. The second experiment attempted to establish why anaphoric noun phrases that are more specific than their antecedents cause problems. It showed that the difficulty did not lie in adding the extra information carried by the anaphor to the representation of the referent. Rather, we suggest, putting extra information in the anaphoric noun phrase disrupts the process of linking that noun phrase to its antecedent.
