Abstract: College students were tested to investigate attentional resources demanded by encoding and retrieval processes in short term memory with a divided attention paradigm. Tone monitoring task was used as a secondary task during encoding, retrieval or both. Results of free recall and serial recall experiments consistently showed that memory performance was significantly impaired while divided attention at encoding, but unaffected while divided attention at retrieval, compared wtih that of full attention condition. The data suggested that encoding processes of short-term memory demand relatively large attentional resources, while retrieval processes in short-term memory demand little of them.
