Emotion Induced Blindness (EIB) refers to the impairment in the identification of a neutral target image that follows a threatening or fearful distractor image. It has been suggested that valence plays a significant role in driving the perceptual impairment in EIB. Recent findings from the literature suggest that arousal has a very important role in biasing early cognitive functions. Hence, in the present study, we systematically investigate the role of valence (Experiment 1) and arousal (Experiment 2) in determining the impairment in EIB. The results suggest that when valence is controlled for, the stimuli with higher arousal level lead to greater impairment in target detection. Moreover, under high arousal condition, both positive and negative stimuli lead to significantly greater impairment in target detection. Present study suggests that impairment in EIB is sensitive to the arousal component of the emotional image as compared to valence. The arousal biased competition account that explains the effect of arousal on cognitive processing can sufficiently explains the current results.
情绪诱发失明(EIB)是指在中性目标图像识别方面出现的障碍,该障碍出现在呈现威胁性或恐惧性干扰图像之后。有人提出,效价在引发EIB中的感知障碍方面起着重要作用。文献中的最新研究结果表明,唤醒在影响早期认知功能方面具有非常重要的作用。因此,在本研究中,我们系统地探究了效价(实验1)和唤醒(实验2)在确定EIB障碍中的作用。结果表明,在控制效价的情况下,唤醒水平较高的刺激会导致目标检测方面更大的障碍。此外,在高唤醒条件下,积极和消极刺激都会导致目标检测方面显著更大的障碍。本研究表明,与效价相比,EIB中的障碍对情感图像的唤醒成分更为敏感。解释唤醒对认知加工影响的唤醒偏向竞争理论能够充分解释当前的结果。
