摘　　要：负启动的研究是考察选择性注意中抑制机制的基本实验范式。本研究选取不同难度的刺激材料,使用经典的负启动实验范式,分别从增加目标选择难度和干扰项个数两个方面考察了大学生被试的汉字特性负启动效应。结果发现:在目标和干扰项互为形似字以及多个干扰项的情况下,被试的特性负启动效应均消失。此结果为注意的资源分配理论提供了进一步的证据。Negative priming is a kind of basic experimental paradigm that is used to investigate the inhibition in selective attention. Negative priming paradigm of identity is used with Chinese characters to investigate the inhibition ability of the undergraduates. The experimental condition varies from two aspects in which the target and the distractors are two Chinese characters that are similar in shape and both the prime stimulus and the probe stimulus are including one target and three distractors. The results showed that the negative priming would disappear with the increasing difficulty in selecting thetarget, which provides the evidence to the resource assignment theory of attention. 
