拒绝敏感性（Rejection sensitivity，RS）是一种焦虑地期待、容易感知并对拒绝做出强烈反应的倾向。本研究采用惊吓探测范式，考察了高RS者的情感防御动机系统是否被拒绝事件自动激活。刺激是描绘拒绝（霍珀）和接受（雷诺阿）的具象绘画，以及消极或积极效价的非具象绘画（罗斯科和米罗分别）。当RS高的人看到拒绝主题时，与他们看到非代表性消极主题时相比，眨眼惊吓幅度增强。与非表征性积极主题相比，在观看接受主题时，惊吓幅度没有减弱。总的来说，研究结果提供的证据表明，对于RS高的人，拒绝线索自动激活防御性动机系统，但接受线索不会自动激活食欲动机系统。
Rejection sensitivity (RS) is the disposition to anxiously expect, readily perceive, and intensely react to rejection. This study used the startle probe paradigm to test whether the affect-based defensive motivational system is automatically activated by rejection cites in people who are high in RS. Stimuli were representational paintings depicting rejection (by Hopper) and acceptance (by Renoir), as well as nonrepresentational paintings of either negative or positive valence (by Rothko and Miro, respectively). Eyeblink startle magnitude was potentiated in people high in RS when they viewed rejection themes, compared with when they viewed nonrepresentational negative themes. Startle magnitude was not attenuated during viewing of acceptance themes in comparison with nonrepresentational positive themes. Overall, the results provide evidence that for people high in RS, rejection cues automatically activate the defensive motivational system, but acceptance cues do not automatically activate the appetitive motivational system.
