This set of materials contains .mp3 files of a female speaker reading lists of categorized words. See DeSoto and Roediger (2014), in references, for more information. The category name is read at the beginning of each list, followed by a 4 s pause, followed by 10 category items presented once every 2 s. The first numeral in the filename, ranging from 1-12, indicates the category. The character indicates whether the items presented were either the even-numbered or odd-numbered items from the source list. The final numeral indicates which of two random orders are presented in the file.
