In an incidental learning paradigm, recall and recognition memory were shown to be significantly better for words rated on pleasantness than on any of the other six semantic dimensions (concreteness, imagery, categorizability, meaningfulness, familiarity, and number of attributes) recently used for scaling of 2,854 words by Toglia and Battig (1978). Pleasantness ratings are also relatively uncorrelated with ratings on these other six dimensions, and the pattern of memory differences between these seven dimensions corresponds closely to differences in dimensional distinctiveness, as indexed by the average correlation of each dimension with the other six dimensions as reported by Toglia and Battig (1978). Word subsets with high and low mean ratings on all seven dimensions showed comparable dimensional differences in memory, but high words were both recalled and recognized better than were low words.
