Description
Social scientists from many disciplines have examined trust, including trust between those with different religious affiliations, emotional antecedents of trust, and physiological correlates of trust. However, little is known about how all of these factors intersect to shape trust behaviors. The current study aimed to examine physiological responses while individuals engaged in a trust game with a religious in-group or out-group member. Participants were randomly assigned to one of four conditions in which they were presented with the target’s profile before playing the game. In each of the conditions the target was described as either Catholic or Muslim and as someone who engaged in either costly signaling or anti-costly signaling behavior. In addition to assessing the amount of money invested as a behavioral measure of trust, physiological responses, specifically cardiac interbeat interval (IBI) and respiratory sinus arrhythmia (RSA), were measured. I hypothesized that when playing the trust game with a Catholic target as opposed to a Muslim target, Christian participants would (1) report being more similar to the target, (2) trust the target more, (3) invest more money in the target, (4) have a more positive outlook on the amount invested, and (5) show greater cardiorespiratory down-regulation, reflected by increases in IBI and RSA. Findings revealed that Christian participants reported greater similarity and showed a non-significant trend toward reporting a more positive outlook on (greater confidence in/satisfaction with) their investment decision when playing a Catholic versus Muslim target. Additionally, Christian participants who played an anti-costly signaling Catholic target showed greater cardiorespiratory down-regulation (increases from baseline for IBI, reflecting slower heart rate, and increases in RSA) than Christian participants who played an anti-costly signaling Muslim target. Results from this study echo previous findings suggesting that perceived similarity may facilitate trust. Findings also are consistent with previous research suggesting that religious ingroup or outgroup membership may not be as influential in shaping trust decisions if the trustee is costly signaling; for anti-signaling, however, cardiorespiratory down-regulation to a religious ingroup member may be apparent. These physiological signals may provide interoceptive information about a peer’s trustworthiness.

Description
Literature was reviewed about how synchrony occurs in infant-parent dyads, in emotion, and physiologically in couple dyads. Social baseline theory suggests that both conversation and interpersonal touch confer benefits by reducing burden on the participants through coregulatory processes. The current study examined how affectionate touch and positive conversation influenced physiological synchrony, a potential mechanism of physiological coregulation, in couples. Because synchrony is believed to occur within the autonomic nervous system, in the present study, physiological synchrony was measured using cardiac interbeat interval (IBI) as an indicator of autonomic nervous system activation. Couples were assigned to one of four conditions: interpersonal touch with positive conversation, interpersonal touch without conversation, positive conversation with no interpersonal touch, and neither interpersonal touch nor conversation. We hypothesized that 1) IBI synchrony between spouses within the real data would be significantly higher than within a phase-shuffled version of the data; and 2) synchrony would be strongest in the touch-talk condition, followed by the touch-no talk condition, followed by the talk-no touch- condition, and finally by the no touch-no talk condition. We also investigated whether there was a tendency for husbands or wives to serve as leader or follower in the four conditions. Using windowed lagged cross-correlations, we found that synchrony within the real data was stronger than synchrony within the shuffled data, suggesting that it reflects an ongoing interpersonal process. Next, we found that there was significantly greater synchrony in the touch-talk than in the touch-no talk condition, marginally greater synchrony in the touch-no talk condition than in the no touch-talk condition, and significantly greater synchrony in the no touch-talk than in the no touch-no talk conditions, suggesting that talk, rather than touch, was driving these synchrony levels. We also found that the only condition with a significant level of leading-following pattern was the no touch-talk condition. More husbands than wives led the covariation in IBI when couples were conversing but not touching. When touch was included this effect did not occur. Future research should include potential moderators such as marital satisfaction and investigate whether seeing one’s partner influences synchrony.
