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 scores (after deduction of false alarms) and discrimination (d') scores in the immediate test, and a superior net recognition and discrimination of secondary sentences in the delayed test. It is concluded that the inferential hypothesis is consistent with most of the results, and that the probability of coding and retention does not differ as a function of sentence importance, though main information may be retrieved more easily than less important information.
