Past research suggests that a time criterion guides responding in speeded word recognition tasks. The time-criterion account has been challenged, however, because it incorrectly predicts equivalent latencies for stimuli of differing difficulty when those stimuli are presented in the same trial block. By requiring participants to perform a lexical decision or naming task but to respond only once they had estimated that 1 sec had elapsed, we investigated the idea that stimulus difficulty effects in response latency might be at least partially due to time perception processes. Consistent with this idea, the participants produced shorter estimates of 1-sec intervals when processing easier stimuli (i.e., time seemed to pass faster when easier stimuli were processed). The implication is that understanding speeded word recognition performance will require looking beyond processes involved in acquiring information about the presented stimulus and examining more general response processes.
过去的研究表明，时间标准指导着快速单词识别任务中的反应。然而，时间标准理论受到了挑战，因为当不同难度的刺激在同一试验块中呈现时，它错误地预测了这些刺激的等效潜伏期。通过要求参与者执行词汇判断或命名任务，但仅在他们估计已经过了1秒后才做出反应，我们研究了反应潜伏期的刺激难度效应可能至少部分归因于时间感知过程的观点。与这一观点一致的是，参与者在处理较容易的刺激时对1秒间隔的估计较短（即，当处理较容易的刺激时，时间似乎过得更快）。这意味着，要理解快速单词识别表现，需要超越获取有关呈现刺激信息的过程，审视更一般的反应过程。
