在快速序列视觉呈现(RSVP)中,当不同干扰物中出现的2个不同的视觉目标间隔在400 ms以内时,第二个目标的检测和识别相对于较长的时间间隔而减少。这种现象被称为注意眨眼(attention blink, AB),是由于第一个目标暂时占用了有限容量的注意系统,从而减少了处理第二个目标的可用资源。虽然在许多刺激类型中都能可靠地获得AB,但在人脸中还没有发现AB。在本研究中,作者调查了这种免疫的基础。揭示AB发生在面部和其他类别内部和之间的情况,作者证明,多通道模型不能解释AB对面部的影响。作者认为,人脸在干扰物序列中的感知显著性以及可用资源决定了在RSVP中人脸是否眨眼。
When 2 different visual targets presented among different distracters in a rapid serial visual presentation (RSVP) are separated by 400 ms or less, detection and identification of the 2nd targets are reduced relative to longer time intervals. This phenomenon, termed the attentional blink (AB), is attributed to the temporary engagement of a limited-capacity attentional system by the 1st target, which reduces resources available for processing the 2nd target. Although AB has been reliably obtained with many stimulus types, it has not been found for faces. In the present study, the authors investigate the underpinnings of this immunity. Unveiling circumstances in which AB occurs within and across faces and other categories, the authors demonstrate that a multichannel model cannot account for the absence of AB effects on faces. The authors suggest instead that perceptual salience of the face within the distracters’ series as well as the available resources determine whether or not faces are blinked in RSVP.
