本研究通过两个实验考察了启动强度在阈下视觉运动启动中的作用。在实验1中，被试分别操纵了初始/目标相容(相容和不相容)和前置客体类型(杂乱线条，强掩蔽；矩形轮廓，弱掩蔽)。在矩形条件下，观察到显著的负相容效应(NCE)，而在直线条件下，没有发现相容效应。然而，当在实验2中引入一个新的变量-质数时长时，长方形条件下的NCE随着质数时长的增加而反转，而NCE保持在直线条件下。这一结果与增加素数持续时间导致素数表征在矩形条件下太强而在直线条件下足以可靠地触发抑制的说法是一致的。研究结果表明，最佳表征在潜意识视觉运动启动中具有因果作用。
This study investigated the role of representation strength of the prime in subliminal visuomotor priming in two experiments. Prime/target compatibility (compatible and incompatible) and preposed object type (jumbled lines, strong masking; and rectangular outlines, weak masking) were manipulated in Experiment 1. A significant negative compatibility effect (NCE) was observed in the rectangle condition, whereas no compatibility effect was found in the line condition. However, when a new variable, prime duration, was introduced in Experiment 2, the NCE was reversed with an increase in the prime duration in the rectangle condition, whereas the NCE was maintained in the line condition. This result is consistent with the claim that increasing the prime duration causes the prime representation to be too strong for inhibition in the rectangle condition but strong enough to reliably trigger inhibition in the line condition. The findings demonstrated that prime representation has a causal role in subliminal visuomotor priming.
