Effects of sentence importance on text recall and recognition: The inferential hypothesis

Abstract

Abstract The hypothesis that sentences with important information are more likely to be remembered than less important sentences because the former are inferred to a greater extent than the latter, was explored. In three previous studies, sentence importance in the structure of texts had been established: Main sentences were assigned higher importance ratings, and recalled and recognised better than secondary sentences. In the present experiment, the subjects read two out of six 500-word texts at their own pace and performed a recall or a recognition test 8 min and 7 days later. Different text versions were written; in each version, one main sentence and one secondary sentence were removed from the original texts. me results showed: (1) a higher false alarm rate and intrusion proportion for main sentences compared to secondary sentences; (2) superior net recall scores (after deduction of intrusions) and memory scores (after correction for guessing) for main sentences; but (3) equivalent net recognition sc...
