Reading as interference for remembering of self-help words
Toews, Stuart Berl
Information in self-help psychology books may affect memories by interfering with accurate recall of past events. These effects were evaluated by investigating the retroactive interference of memory for self-help information on previously learned material. One-hundred-seve ty-five women in introductory psychology served in a 2 x 2 x 2 MANOVA design varying book reading (present/absent), amount of learning (processing once or twice), and retention interval (2 or 3 weeks). Participants learned a list of words (half from the book) in Session 1 and in Session 2 evaluated a new list of words to discriminate which words appeared in the first list and which did not. A complex set of significant results appeared in the data. In general, however, there was not strong support for the hypothesis that information in self-help books interferes with previously learned verbal material.
