Clinically significant fears and phobias can be acquired vicariously. Witnessing a demonstrator’s defensive reaction to potentially dangerous objects and situations can instill conditioned threat responses in the observer. The present study concentrates on individual differences in this social learning process. Specifically, we hypothesized that dispositional empathy modulates vicarious threat conditioning. We examined university students’ (N = 150) conditioned threat responding after they observed strangers undergo Pavlovian threat conditioning. There was evidence of a substantial conditioned defensive response (Cohen’s d = 0.66), as indexed by elevated skin conductance reactions during participants’ direct exposure to the vicariously conditioned stimuli. Contrary to expectations, indices of dispositional empathy were weakly related to the size of conditioned responses (median r = .04). Our results confirm that vicarious threat learning can be evaluated experimentally, but they do not support the hypothesis that empathy amplifies this process.

AbstractPanic disorder (PD) is characterized by a dysfunctional defensive responding to panic-related body symptoms that is assumed to contribute to the persistence of panic symptomatology. The present study aimed at examining whether this dysfunctional defensive reactivity to panic-related body symptoms would no longer be present following successful cognitive behavior therapy (CBT) but would persist when patients show insufficient symptom improvement. Therefore, in the present study, effects of CBT on reported symptoms and defensive response mobilization during interoceptive challenge were investigated using hyperventilation as a respiratory symptom provocation procedure. Changes in defensive mobilization to body symptoms in the course of CBT were investigated in patients with a primary diagnosis of PD with or without agoraphobia by applying a highly standardized hyperventilation task prior to and after a manual-based CBT (n = 38) or a waiting period (wait-list controls: n = 20). Defensive activation was indexed by the potentiation of the amygdala-dependent startle eyeblink response. All patients showed a pronounced defensive response mobilization to body symptoms at baseline. After treatment, no startle reflex potentiation was found in those patients who showed a clinically significant improvement. However, wait-list controls and treatment non-responders continued to show increased defensive responses to actually innocuous body symptoms after the treatment/waiting period. The present results indicate that the elimination of defensive reactivity to actually innocuous body symptoms might be a neurobiological correlate and indicator of successful CBT in patients with PD, which may help to monitor and optimize CBT outcomes.

We are wasting our time with the theory of bad apples [in medicine] and our defensive response to it in health care today, and we can best begin by freeing ourselves from the fear, accusation, defensiveness, and naivete of an empty search for improvement through inspection and discipline. The theory of continuous improvement proved better in Japan; it is proving itself again in American industries willing to embrace it, and it holds some badly needed answers for American health care.

The hypothesis tested was that adults of higher social status complete the Crowne and Marlowe Social Desirability Scale more honestly and less defensively than adults belonging to lower social classes. 341 parents of 215 different families were tested during home interviews. The hypothesis was verified among women, but not among men. These results suggest that social status is associated with defensive response style, perhaps reflecting at the same time academic education and cognitive-intellectual functioning.

This chapter reassesses the origins and consequences of the Hispano-Moroccan War of 1859–1860, conventionally seen as a war driven by domestic Spanish politics. Examining military correspondence pertaining to navigation around Melilla and the Alboran Sea, this chapter argues that the invasion was a defensive response to growing concern that France and Britain were granting legal protection to Moroccan tribes that were hostile to Spain. Because the Spanish prime minister Leopoldo O’Donnell could not declare war against either of those European powers, he launched an invasion against the Moroccan sultan. The goal was not to gain territory but to gain influence in the sultan’s court and legal rights to patrol navigation on the eastern Riffian coast. By this measure, the war was more significant and successful than generally believed.
