Although Schustack and Anderson presented a situation in which providing a referent improved recognition accuracy, an experiment described by Bower, Black, and Turner reversed this result. In their experiment, subjects studied 1, 2, or 3 stories involving the same script such as visiting a health professional. Their subjects were asked to give recognition ratings of sentences on a 1-7 scale (1 = high confidence rejection, 4 = guessing, 7 = high confidence acceptance). The recognition ratings for studied sentences did not vary much as a function of the number of stories studied. On the other hand, the ratings for story related foils did increase from 3.91 to 4.62 to 4.81 for one, two and three stories, respectively. Significantly, the probability that these foils appeared in another story varied with number of stories-0% for 1 story, 50% for 2 stories, and 100% for 3 stories.
