自Titchener [E.B. Titchener，Lectures on the Elementary Psychology of Feeling and Attention，Macmillan，纽约，1908]发表了他的有影响力的主张，即关注特定的感觉模态（或位置）可以加速在该模态（或位置）中呈现的刺激的相对到达时间。然而，迄今为止，证明存在先前入账的证据好坏参半。在本研究中，我们使用了视听一致性判断任务，试图规避在这一领域的先前研究中固有的潜在的方法论混淆。受试者使用恒定刺激的方法，在不同的刺激起始时间（SOA）对听觉和视觉刺激进行同时与连续的判断反应。在不同的试验中，参与者被要求注意听觉或视觉模态，或者在两种模态之间平均分配注意力。包含模态内刺激对的试验的概率（例如，视觉-视觉或听觉-听觉）的注意力集中的块中增加，以鼓励参与者遵循指示。这种注意力操纵调制的感知的一致性：视觉刺激导致听觉刺激的一个显着更小的时间间隔被感知的一致性时，注意力被定向到视觉比当它被定向到听觉。这些结果为视听在先进入的存在提供了第一个明确的证据。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
It is almost one hundred years since Titchener [E.B. Titchener, Lectures on the Elementary Psychology of Feeling and Attention, Macmillan, New York, 1908] published his influential claim that attending to a particular sensory modality (or location) can speed up the relative time of arrival of stimuli presented in that modality (or location). However, the evidence supporting the existence of prior entry is, to date, mixed. In the present study, we used an audiovisual simultaneity judgment task in an attempt to circumvent the potential methodological confounds inherent in previous research in this area. Participants made simultaneous versus successive judgment responses regarding pairs of auditory and visual stimuli at varying stimulus onset asynchronies (SOAs) using the method of constant stimuli. In different blocks of trials, the participants were instructed to attend either to the auditory or to the visual modality, or else to divide their attention equally between the two modalities. The probability of trials containing intramodal stimulus pairs (e.g., vision-vision or audition-audition) was increased in the focused attention blocks to encourage participants to follow the instructions. The perception of simultaneity was modulated by this attentional manipulation: Visual stimuli had to lead auditory stimuli by a significantly smaller interval for simultaneity to be perceived when attention was directed to vision than when it was directed to audition. These results provide the first unequivocal evidence for the existence of audiovisual prior entry. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
