Abstract
The effects of semantic and acoustic similarity in short-term memory were examined in an experiment employing an RI paradigm. In assessing similarity effects, signal-detection measures, Type II operating characteristics, were utilized in addition to percent recalled; the former suggested that both semantic and acoustic similarity between OL and IL were important in affecting recall, while the latter revealed no effects of similarity. The results suggested that memory traces for similar and dissimilar OL items were equal in strength but that noise (due to RI) was stronger for the similar conditions.
