Abstract
Homogeneous experimental (acoustically and semantically related) and control lists were presented to different groups of subjects at either 1 s or 6 s per word. The difference score between these two lists was used as a measure of categorization. Only words in the middle serial positions (representing retrieval from secondary memory) were scored. Clustering was also measured. Slow presentation rate significantly increased categorization of the semantically similar words. This was not true of acoustically similar words. A possible explanation of this is that semantic categorization is time-consuming and acoustic categorization is not. Alternatively, the acoustic similarity effect may be a retrieval effect. The absence of acoustic clustering would seem to fit in with this latter interpretation.Keywords
