作者表明，倾向于接近和避免不简单地由特定的运动模式，但更抽象的功能，产生预期的环境效果。有人声称，将视觉刺激评估为积极或消极会引起特定的运动反应，对消极刺激伸展手臂，对积极刺激收缩手臂。作者表明，一个大的一致性效应（参与者更快地接近愉快的刺激，避免不愉快的刺激，比接近不愉快的刺激，避免愉快的刺激）可以产生一个新的触摸屏范例（实验1），和一致性效应可以逆转的空间（实验2）和非空间（实验3）的反应效果。因此，无意识接近和避免响应激活不是固定的，而是对上下文敏感的，并且具体地基于期望的目标。
The authors show that predispositions to approach and avoid do not consist simply of specific motor patterns but are more abstract functions that produce a desired environmental effect. It has been claimed that evaluating a visual stimulus as positive or negative evokes a specific motor response, extending the arm to negative stimuli, and contracting to positive stimuli. The authors showed that a large congruency effect (participants were faster to approach pleasant and avoid unpleasant stimuli, than to approach unpleasant and avoid pleasant stimuli) could be produced on a novel touchscreen paradigm (Experiment 1), and that the congruency effect could be reversed by spatial (Experiment 2) and nonspatial (Experiment 3) response effects. Thus, involuntary approach and avoid response activations are not fixed, but sensitive to context, and are specifically based on the desired goal.
