Overall, the results provide evidence that for stimuli and that this elicitation occurs automatically, at an early, people high in RS, rejection cues automatically activate the nonverbal stage in the activation of the RS dynamic. We tested these defensive motivational system, but acceptance cues do not au- hypotheses by assessing whether in the face of rejection-relevant cues, tomatically activate the appetitive motivational system. individuals high in RS show heightened potentiation of the startle response, a robust autonomic nervous system indicator of activation in the defensive motivational system (DMS; Lang, Bradley, & Cuthbert, Everyone experiences rejection. Whereas some people respond with 1990; see Dawson, Schell, & Boehmelt, 1999). equanimity, others respond in ways that profoundly compromise their well-being and relationships. To help explain such maladaptive re- actions to rejection, we have proposed a specific cognitive-affective DEFENSIVE MOTIVATIONAL SYSTEM processing disposition, rejection sensitivity (RS; Downey & Feldman, 1996). At the core of this disposition is the anxious expectation of The understanding of how organisms defend themselves against being rejected by people who are important to the self, an expectation threats has increased tremendously as researchers have brought de- developed through exposure to severe and prolonged rejection.

Although this reflex habituates over trials, it threat can be biologically based (e.g., an instinctive threat reaction to can nevertheless be repeatedly evoked within relatively short time seeing a snake) or socially learned (e.g., an expectation of rejection in periods over dozens of trials (Putnam & Roth, 1990). certain social situations). The rationale underlying this paradigm is that when an organism is Research on both animals and humans suggests that when the DMS already in a high-arousal, negatively valenced state, independently is activated by the potential of danger, physiological responses to evoked defensive responses such as the eyeblink response to an un- newly encountered threat-congruent cues are amplified, and physio- expected loud noise are augmented (Lang et al., 1990, 2000). For logical responses to threat-incongruent cues are attenuated. That is, example, when individuals are viewing a picture depicting a gun the organism is oriented to detect cues that are congruent with a state pointing toward them, they show exaggerated startle (indexed by the of threat and to act when confirmatory cues are detected (see Lang et magnitude of their eyeblink response) when disturbed by an unex- al., 2000). The model also indicates that when the appetitive system is pected loud noise.

The magnitude of the startle response to the loud noise is potentiated, however, because CONCEPTUALIZING RS AS A DEFENSIVE MOTIVATIONAL the individual is already in a defensive state due to viewing the un- SYSTEM pleasant, arousing picture. Conversely, when individuals are viewing a positively arousing pictorial stimulus, they are in an appetitive state and Our phenomenological description of the operation of the RS system therefore their independently evoked defensive responses are attenu- closely parallels the operation of the DMS.

Low-RS (LRS) individuals presented in the presence of a phobia-irrelevant negative stimulus are less likely to experience heightened DMS activation in these same (e.g., Hamm, Cuthbert, Globisch, & Vaitl, 1999). situations because they typically deem rejection less probable and of less concern.
