Abstract: | An experiment was conducted using event-related potentials to investigate the old/new effects of the item recognition and the voice source retrieval tasks on drawing. The results indicated that (1) the old/new effect for the voice source retrieval task was much wider than that of the item recognition task; (2) the distributive characteristics of the voice source memory effect were different from those in previous studies; (3) the old/new effects for target and non-target-old drawings were similar. These results demonstrated that the voice source retrieval task is more difficult than the item recognition task for drawing, which supports the dual-process model. The experimental material and the source characteristic regulate the spatial and temporal distributions of the old/new effect for the voice source retrieval task together. |
