“…Following previous studies (e.g., Armel and Ramachandran, 2003) we used SCR to assess affective reactivity (see Figner and Murphy, 2010; Boucsein, 2011). SCR is a standard physiological measure and the best predictor of psychological arousal, and the fact that participants cannot control their SCR voluntarily makes it a reliable measure.…”

The rubber hand illusion refers to the observation that participants perceive “body ownership” for a rubber hand if it moves, or is stroked in synchrony with the participant's real (covered) hand. Research indicates that events targeting artificial body parts can trigger affective responses (affective resonance) only with perceived body ownership, while neuroscientific findings suggest affective resonance irrespective of ownership (e.g., when observing other individuals under threat). We hypothesized that this may depend on the severity of the event. We first replicated previous findings that the rubber hand illusion can be extended to virtual hands—the virtual-hand illusion. We then tested whether hand ownership and affective resonance (assessed by galvanic skin conductance) are modulated by the experience of an event that either “impacted” (a ball hitting the hand) or “threatened” (a knife cutting the hand) the virtual hand. Ownership was stronger if the virtual hand moved synchronously with the participant's own hand, but this effect was independent from whether the hand was impacted or threatened. Affective resonance was mediated by ownership however: In the face of mere impact, participants showed more resonance in the synchronous condition (i.e., with perceived ownership) than in the asynchronous condition. In the face of threat, in turn, affective resonance was independent of synchronicity—participants were emotionally involved even if a threat was targeting a hand that they did not perceive as their own. Our findings suggest that perceived body ownership and affective responses to body-related impact or threat can be dissociated and are thus unlikely to represent the same underlying process. We argue that affective reactions to impact are produced in a top-down fashion if the impacted effector is assumed to be part of one's own body, whereas threatening events trigger affective responses more directly in a bottom-up fashion—irrespective of body ownership.

“…High physiological sensitivity would be reflected in higher average amplitude. The method applied for calculating the response average (stimulus average) was based on a well-documented methodology applied in the field of EDA (Boucsein, 2012). We were specifically interested in skin conductance response (SCR), the phasic change in EDA -a fast change in the amplitude of the signal relative to baseline.…”

“…Minimal response criterion was set to 0.02 μ S, and responses that did not pass this criterion were scored as 0. SCR scores were then ztransformed to normalize the distributions (Boucsein, 2012). Clean SCRs were then used for subsequent statistical comparisons.…”

“…Ag-AgCl electrodes were attached to the middle and index fingers from the hand not receiving shocks. A conducting gel was used to improve signal quality, in accordance with standard recommendations (Boucsein, 2012). Electric shocks (aversive stimuli) were delivered using a STM200 module (BIOPAC Systems Inc., Goleta, CA, USA).…”

1Humans, like other social animals, learn about threats and safety in the environment through 2 social cues. Yet, the processes that contribute to the efficacy of social safety learning during 3 threat transmission remain unknown. Here, we developed an experimental dyadic model 4 during which live pairs of participants underwent an associative threat learning and extinction 5 procedure followed by a threat recovery test. In three separate social groups, we manipulated
