词汇决策任务的性能高度依赖于决策标准。这些标准可能受到速度与准确性指令以及单词/非单词比例的影响。实验1表明，在快速反应的指示下，错误反应相对于正确反应速度更快。实验2表明，对不太可能的刺激的反应比对更可能的刺激的反应更慢，更不准确。两个实验的数据都支持词汇决策的扩散模型[Ratcliff， R., Gomez， P., & McKoon， G. (2004a)]。词汇决策任务的扩散模型。心理评论，11,159-182]。同时，这些数据为流行的词汇决策截止日期模型提供了证据。截止日期模型假设“非词”反应是在“词”反应超时后才给出的——因此，截止日期模型无法解释来自实验条件的数据，在实验条件下，“非词”反应系统地比“词”反应快。(C) 2007爱思唯尔公司版权所有。
Performance in the lexical decision task is highly dependent on decision criteria. These criteria can be influenced by speed versus accuracy instructions and word/nonword proportions. Experiment I showed that error responses speed up relative to correct responses under instructions to respond quickly. Experiment 2 showed that responses to less probable stimuli are slower and less accurate than responses to more probable stimuli. The data from both experiments support the diffusion model for lexical decision [Ratcliff, R., Gomez, P., & McKoon, G. (2004a). A diffusion model account of the lexical decision task. Psychological Review, 111, 159-182]. At the same time, the data provide evidence against the popular deadline model for lexical decision. The deadline model assumes that "nonword" responses are given only after the "word" response has timed out-consequently, the deadline model cannot account for the data from experimental conditions in which "nonword" responses are systematically faster than "word" responses.
