摘要
The co-influence of grammatical markers (connectives) and comprehender goals (directed forgetting cues) on the memory for sentences was examined in three experiments. Participants read statement pairs which were linked by a connective (e.g., because) or stood alone as separate sentences. After each statement, a cue to remember or to forget the preceding statement was presented. In Experiment 1, participants had more difficulty forgetting the second clause in the presence of the connective because than in its absence when statement 1 was to be remembered. In Experiment 2, the pattern of directed forgetting was similar for the connectives because and and, suggesting that one reason why directed forgetting was reduced for the second statement in Experiment 1 was that it merely continued a linguistic structure rather than increasing causal-based inferences. In Experiment 3, the connective was placed after the cue for statement 1, making it more difficult for readers to incorporate the second clause to the first. Under these conditions, the connective did not reduce intentional forgetting. The pattern of results indicates that the goal to forget a phrase has a smaller impact on forgetting when an incoming representation can be readily attached to a TBR representation in working memory as directed by a grammatical marker.
