Abstract

In the present study, 4 experiments were conducted in order to examine the similarity of underlying mechanisms for negative priming effects in a referent size-selection task and other selection tasks. The results were (1) negative priming effects were observed only when the same tasks were used in priming and probe trials, (2) regative priming effects were not observed when only a target stimulus was presented in probe trials, (3) negative priming effects were observed when only one word was presented for 33ms in prime trials, (4) response-stimulus incerval(RSI) did not affect negative priming effcts when RSI was manipulated between subjects. These results indicate that the underlying mechanisms for negative priming effects in the referent size-selecting task and other selection tasks are similar. These results may be explained more easily by the temporal discrimination accounts than by the inhibition and episodic retrieval accounts.
