Abstract

The present study adopted a primed target grasping-categorization task and selected pictures of animals as target stimuli to investigate whether motor inhibition influences the motor interference effect of dangerous animals. The results identified more positive P2 and P3 amplitudes accompanied by larger delta event-related synchronization in the dangerous condition than in the neutral condition, suggesting that compared to neutral animal targets, dangerous animal targets attracted increased attentional resources in early processing and that subjects recruited more cognitive resources to process dangerous animal targets than neutral animal targets. Moreover, the results identified larger theta event-related synchronization (reflecting motor inhibition) in the dangerous condition than in the neutral condition. Thus, the results suggested that prepared motor responses were inhibited to avoid touching dangerous animal targets in the current task, supporting that motor inhibition influences the motor interference effect of dangerous animals based on a primed target grasping-categorization task.

摘要

本研究采用启动目标抓取分类任务，选取动物图片作为目标刺激，探讨运动抑制是否影响危险动物的运动干扰效果。结果发现，在危险条件下，与中性条件相比，P2 和 P3 幅度更大，伴随着更大的 delta 事件相关同步，这表明与中性动物目标相比，危险动物目标在早期处理中吸引了更多的注意力资源，并且受试者招募了更多的注意力资源。与中性动物目标相比，处理危险动物目标的认知资源。此外，结果表明，危险条件下与中性条件下相比，θ 事件相关同步（反映运动抑制）更大。因此，
