Two experiments were carried out to investigate the effects of the self-generated causal and outcome sentences and the precise and imprecise sentences on incidental memory. Subjects were asked to answer the questions about each target followed by free and cued recall tests. One word in each target sentence was used as a cue in cued recall. In the first experiment the type of self-generated sentences was treated as the within-subjects factor. The self-generated outcome sentences led to better free recall than the causal sentences when the sentences were judged as the precise ones. Although there was no performance difference between the precise and the imprecise sentences in free recall, the better performance was observed for the precise sentence in cued recall. In the second experiment the type of self-generated sentences was treated as the between-subjects factor. The causal, the outcome and the associative information groups were provided. There was no performance difference among these groups in both free and cued recall tests. The performance difference between the precise and the imprecise sentences also was not observed in both recall tests. The findings obtained in both experiments were interpreted as showing that there was no difference in effectiveness between the self-generated causal and the self-generated outcome informations and that the precision of the self-generated informations was not critical in incidental memory.
