Abstract

The "Attentional Blink" refers to difficulty in detecting the second of two target stimuli presented in rapid temporal succession. Studies have shown that salient target stimuli, such as one's own name, reduce the magnitude of this effect. Given indications that self-related processing is altered in autism, it is an open question whether this attentional self-bias is reduced in autism. To investigate this, in the current study we utilised an Attentional Blink paradigm involving one's own and others' names, in a group of 24 autistic adults, and 22 neurotypical adults, while measuring EEG. In line with previous studies, the Attentional Blink was reduced when the participant's own name was the second target, with no differences between autistic and neurotypical participants. ERP results show that the effect on the Attentional Blink of one's own name was reflected in increased N2 and P3 amplitudes, for both autistic and nonautistic individuals. This is the first event-related potential study of own-name processing in the context of the Attentional Blink. The results provide evidence of an intact attentional self-bias in autism, both at the behavioural and neural level.

摘要

“注意瞬脱”是指在快速呈现的两个目标刺激中,难以检测到第二个目标刺激。研究表明,显著的目标刺激,如自己的名字,会降低这种效应的幅度。鉴于自闭症患者的自我相关处理会发生改变,自闭症患者的这种注意力自我偏向是否会降低,这是一个悬而未决的问题。为了研究这个问题,在当前的研究中,我们利用了一种注意瞬脱范式,该范式涉及参与者自己和他人的名字,参与者为 24 名自闭症成年人和 22 名神经典型成年人,同时测量了 EEG。与之前的研究一致,当参与者自己的名字是第二个目标时,注意瞬脱会减少,自闭症和神经典型参与者之间没有差异。ERP 结果表明,参与者自己名字对注意瞬脱的影响反映在 N2 和 P3 振幅的增加上,无论是自闭症患者还是非自闭症患者都是如此。这是在注意瞬脱背景下对自身名字处理进行的第一个事件相关电位研究。研究结果为自闭症患者在行为和神经水平上存在完整的注意力自我偏向提供了证据。
