By recording event-related potentials (ERPs) during a dot-probe task, the present study examined the neural dynamics of attentional bias toward height-related words among height dissatisfied males. Sixty male participants screened by Negative Physical Self Scale-Stature Concerns subscale (NPS-S) were assigned into a high height dissatisfaction (HHD) group and a low height dissatisfaction (LHD) group. The results showed that tall-related versus neutral words elicited larger N2pc for both HHD and LHD groups, whereas short-related versus neutral words elicited larger N2pc only for the HHD group. Additionally, an evident Pd was elicited by tall-related words for the HHD group, but not for the LHD group. Taken together, these findings revealed attentional biases toward height-related information for HHD individuals on a neural level. Specifically, HHD individuals showed an enhanced spatial attention oriented toward both tall-related and short-related words, and then, the allocated attention to the tall-related words was terminated by an active suppression mechanism.
通过在点探测任务中记录事件相关电位(ERP),本研究考察了身高不满意男性对与身高相关词汇的注意偏向的神经动力学。通过消极身体自我量表 - 身高关注分量表(NPS - S)筛选出的60名男性参与者被分为高身高不满意(HHD)组和低身高不满意(LHD)组。结果表明,对于HHD组和LHD组,与身高高相关的词汇相对于中性词汇均引发了更大的N2pc,而与身高矮相关的词汇相对于中性词汇仅在HHD组中引发了更大的N2pc。此外,HHD组中与身高高相关的词汇引发了明显的Pd,而LHD组则没有。综上所述,这些发现揭示了HHD个体在神经层面上对与身高相关信息的注意偏向。具体而言,HHD个体对与身高高相关和与身高矮相关的词汇均表现出增强的空间注意,然后,通过一种主动抑制机制终止对与身高高相关词汇的分配注意。
