What determines if the first interaction between strangers will be a pleasant experience? We conducted an experiment to investigate the extent to which the perceived quality of an interaction is influenced by conversation content and context, and we document the physiological changes that are likely to play a role in establishing rapport. Females who did not know each other met in pairs and conducted a gossip- or creativity task, either face-to-face or online. The conversation content had no effect on the (...) quality of online interactions. However in the face-to-face condition gossip was associated with better interaction quality. Tonic electrodermal activity steadily declined throughout the interaction, while phasic electrodermal activity first peaked and then returned to baseline. Neither were related to perceived interaction quality. Heart rate variability dropped at first but then remained stable. A smaller drop in HRV drop corresponded to higher ratings of rapport and liking. Together these results suggest that gossip can improve the quality of a face-to-face interaction between strangers, and support the conjecture that parasympathetic activity is a marker of human openness to social engagement.

Why do some types of settings and some combinations of sensory information induce a sense of dread in humans? This article brings empirical evidence from psychological research to bear on the experience of horror, and explains why the tried-and-true horror devices intuitively employed by writers and filmmakers work so well. Natural selection has favored individuals who gravitated toward environments containing the “right” physical and psychological features and avoided those which posed a threat. Places that contain a bad mix of these (...) features induce unpleasant feelings of dread and fear, and therefore have become important ingredients of the settings for horror fiction and films. This article ap­plies McAndrew and Koehnke’s theory of creepiness to the study of classic horror settings and explores the role played by architecture, isolation, association with death, and other environmental qualities in the experience of creepiness and dread.
