Abstract:

Used a 2*3*2 mixed design, we tested the difference of repeated priming effect between the same conditions and the relevant conditions, under different SOA conditions. The results showed that in a short 167ms SOA, the priming effect between repeat/same and repeat/related had no difference, and the relevant prime repetition did not lead to the reduction of semantic priming effect. In a long 1200ms SOA, there was a significant difference between repeat/same and repeat/related, and the relevant prime repetition do lead to the reduction of semantic priming effect, meanwhile the repeat/same did not lead to any reduction of semantic priming effect. After the offset of expectancy effect and the decay of semantic activation, we believe that the priming effect difference between repeat/same and repeat/related in 1200ms SOA is because of the obstruction of the initiation of spreading. Based on the results and the principle of least effort, we believe that in the long SOA conditions, there is no spreading occurred as scheduled. Therefor we concluded that prime repetition does affect the initiation of spreading in the long SOA, when P2 is not actually masked and can be clearly recognized.

摘要：

采用重复启动范式探讨语义启动效应减少的机制。结果发现，在SOA为短的167ms条件下，重复/相同和重复/相关的启动效应无差异，且重复/相关启动并未导致语义启动效应的减少；而在SOA为长的1200ms条件下，重复/相同和重复/相关的启动效应差异显著，且重复/相关启动导致了语义启动效应的减少，而重复/相同未导致语义启动效应的减少。在抵消了期望和消退的作用后，在SOA为1200ms条件下所得到的重复/相同和重复/相关启动效应的差异，是由于扩散受到了阻碍而导致的。这一结论支持了激活扩散是有一定条件的观点。
