2 Abstract We tested the effect of chunking and rehearsal on memorization by subjecting participants to a word recall test of either categorically grouped, or non-grouped words. A control group was also made to complete a mathematics sheet after being exposed to the words in a grouped and non-grouped format. Subjects given words grouped taxonomically recalled words more effectively than those grouped non-taxonomically, supporting previous findings by Bousfield and Puff. Subjects’ ability to recall hierarchal groups of words more easily without the math sheet also supported findings Bower. We explain our experiment and its’ results, and the implications of these results on previous findings and cognitive theories on the topic. Introduction The experiment was designed to study the differences between clustering and rehearsal on memory retention. The inspirations for the experiment were a study by Bower on retrieval schemes in categorized word lists(1969). The study examined the effect of hierarchal grouping of words on their memorization. Another inspiration was a study by W.A. Bousfield and C.R. Puff, which found that words that are related taxonomically and used cluster based grouping recall more frequently than words that were related nontaxonomically(1965). Based on Bousfield and Puff’s research, and Bower’s research, it is hypothesized that taxonomically similar words given in chunk form, and allowed rehearsal learning time would be recalled most effectively, due to the rehearsal effect. In this study, the random math group will perform the worst. The most words will be recalled by the cluster rehearsal group, because they have the two most reliable methods of memory according to the research study by Bower. This research study notes that clustered
