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 1 showed that error responses speed up relative to correct responses under instructions to respond quickly. Experiment 2 showed that 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, Gomez, & McKoon, 2004). 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.

词汇决策任务中标准转移的扩散模型解释

词汇决策任务的表现高度依赖于决策标准。这些标准可能会受到速度与准确度指令以及单词/非单词比例的影响。实验 1 表明，在快速响应的指令下，错误响应相对于正确响应加快。实验 2 表明，对不太可能的刺激的反应比对更有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, Gomez, & McKoon, 2004）。同时，这些数据为词汇决策的流行截止日期模型提供了证据。截止日期模型假设只有在“单词”响应超时后才给出“非单词”响应——因此，
