<!-- TITLE: Social support & persuasion --> <!-- SUBTITLE: --> # Finding the buzz in the brain [The default mode network](https://en.wikipedia.org/wiki/Default_mode_network) is one of the first hits I got when looking for mPFC and PFC activation, after seeing they were highly correlated ([here](https://neurosynth.org/analyses/terms/pcc/)). # Why is social support protecting? > The Relationship Between Social Support and Processes: A Review With Emphasis on Underlying Mechanisms and Implications for Health (1996) Some positive effects of social support on cardiovascular, endocrine, and immune systems. + Health-related behaviors and these associations + Stress-buffering + Familial sources of support may be important + Emotional support is at least one dimension of social support ## Previous research + Socially isolated individuals get sick and die more often # Social isolation $\to$ lower Ab responses? > Loneliness, Social Network Size, and Immune Response to Influenza Vaccination in College Freshmen (2005) + Daily digital diaries for 2 weeks (starting 2 days prevaccination) + "Ecological momentary assessments" + Salivary cortisol for 5 days prevaccination + 3.5 months of biweekly postvaccination questionairres + Ab levels measured at vaccination, 1 month after, and 4 months after # Immune and endocrine, stigmatization and pride > Perceived Stigmatization, Ingroup Pride, and Immune and Endocrine Activity: Evidence From a Community Sample of Black and Latina Women (2013) [Collective self-esteem scale](https://faculty.psy.ohio-state.edu/crocker/lab/documents/CSEscale_general_version.pdf) # Neural Responses > From Neural Responses to Population Behavior: Neural Focus Group Predicts Population-Level Media Effects (2012) (they love the word *orthogonal*, presumably meaning unrelated) -- in a study orthogonal to the present one. + Correlating call volume to 1-800-QUIT-NOW to neural activation in their ROI depending on ads presented + Overall neural activity across all ads "predicted" (correlated with) smoking reduction after watching, beyond self-reports + 31 participants, heavy smokers who really wanted to quit + Wide age, ethnicity, socioeconomic diversity + Mean neural activity in MPFC ROI rated C > B > A, while experts and participants put C last. + C > B > A was also more frequent individually than by chance (33%) + B > A > C was most frequent in self-reports + The neural ordering was confirmed by the % increase in call volume
