【摘要】：为考察阈上、阈下不同面孔表情下的注视线索提示效应,实验以阈上和阈下面孔的不同注视朝向为提示线索,同时变化面孔表情,要求被试迅速和准确地对随后出现的靶刺激(大写字母)的呈现位置做出判断。结果显示,在阈上呈现条件下,注视线索提示效应显著,且该效应不受面孔表情的影响。在阈下呈现条件下,注视线索提示效应显著,但该效应受到了面孔表情的调节,表现为在注视线索无效时,判断目标位置所需反应时在正性、负性面孔表情下显著长于中性面孔条件。上述结果说明,阈上知觉时,面孔表情虽被清晰感知,但个体自上而下的控制机制使其被忽略,因而未能影响个体的注意偏向;阈下知觉时,面孔表情得到自动加工,并影响了个体的注意偏向。
[Abstract]:In order to investigate the cues of gaze under different facial expressions above threshold and subthreshold, the experiment took the different gaze orientation of suprathreshold and subthreshold faces as cues, and changed the facial expressions at the same time. Participants were asked to quickly and accurately judge the location of the presentation of subsequent target stimuli (capital letters). The results showed that the effect of fixation cues was significant under the condition of suprathreshold presentation, and the effect was not affected by facial expressions. Under the condition of subthreshold presentation, the effect of fixation cues was significant, but the effect was regulated by facial expressions, which showed that when the fixation cues were ineffective, the response needed to judge the target location was positive. Negative facial expressions were significantly longer than neutral facial conditions. The above results show that the facial expression is clearly perceived in suprathreshold perception, but the top-down control mechanism of the individual makes it neglected, so it can not affect the individual attention bias; When subliminal perception, facial expression is automatically processed and affects individual attention bias.
