Experimental evidence of massive-scale emotional contagion through social networks
Abstract: Significance We show, via a massive ( N = 689,003) experiment on Facebook, that emotional states can be transferred to others via emotional contagion, leading people to experience the same emotions without their awareness. We provide experimental evidence that emotional contagion occurs without direct interaction between people (exposure to a friend expressing an emotion is sufficient), and in the complete absence of nonverbal cues.

“…Moreover, two sources of contagion were identified, 1) a parent-comment and 2) a sequentially preceding child-comment. The results are in line with previous research on online emotional contagion and thus add one more evidence of negative emotional contagion (Kramer et al, 2014).…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD).
Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD.
The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC).
Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Thus, even a 1% difference could equate to tens of thousands of additional reads (see Discussion for additional commentary on effect sizes). Moreover, these effect sizes are consistent with other studies that have evaluated the impact of language effects on behavior in the wild ( 31 ).…”

“…That is, the degree to which various measures of complexity can identify petitions that receive high or low numbers of supporters, or those that are victorious from those that fail, should be examined in future research with more sophisticated natural language processing techniques. Third, the effect sizes in the current article are small, but consistent with those reported in other research (Kern et al, 2014; Kramer et al, 2014; Markowitz, 2022; Seraj et al, 2021). Crucially, the robustness checks suggested that even at smaller sample thresholds, most relationships were consistent in size.…”
