The prior entry hypothesis contends that attention accelerates sensory processing, shortening the time to perception. Typical observations supporting the hypothesis may be explained equally well by response biases, changes in decision criteria, or sensory facilitation. In a series of experiments conducted to discriminate among the potential mechanisms, observers judged the simultaneity or temporal order of two stimuli, to one of which attention was oriented by exogenous, endogenous, gaze-directed, or multiple exogenous cues. The results suggest that prior entry effects are primarily caused by sensory facilitation and attentional modifications of the decision mechanism, with only a small part possibly due to an attention-dependent sensory acceleration.

先入假设认为注意力加速了感觉处理，缩短了感知时间。支持假设的典型观察结果可以通过反应偏差、决策标准的变化或感官促进同样得到很好的解释。在为区分潜在机制而进行的一系列实验中，观察者判断两个刺激的同时性或时间顺序，其中一个是由外源性、内源性、凝视导向或多个外源性线索导向的。结果表明，先入效应主要是由感觉促进和决策机制的注意修改引起的，只有一小部分可能是由于依赖于注意的感觉加速。
