Regional and network neural activity reflect men's preference for greater socioeconomic status during impression formation.

ABSTRACT: Evidence from social psychology suggests that men compared to women more readily display and pursue control over human resources or capital. However, studying how status and gender shape deliberate impression formation is difficult due to social desirability concerns. Using univariate and multivariate fMRI analyses (n?=?65), we examined how gender and socioeconomic status (SES) may influence brain responses during deliberate but private impression formation. Men more than women showed greater activity in the VMPFC and NAcc when forming impressions of high-SES (vs. low-SES) targets. Seed partial least squares (PLS) analysis showed that this SES-based increase in VMPFC activity was associated with greater co-activation across an evaluative network for the high-SES versus low-SES univariate comparison. A data-driven task PLS analysis also showed greater co-activation in an extended network consisting of regions involved in salience detection, attention, and task engagement as a function of increasing target SES. This co-activating network was most pronounced for men. These findings provide evidence that high-SES targets elicit neural responses indicative of positivity, reward, and salience during impression formation among men. Contributions to a network neuroscience understanding of status perception and implications for gender- and status-based impression formation are discussed.

Project description:ObjectivesIn the general population, the lower socioeconomic status (SES) associates with greater systemic and arterial inflammation and a greater risk of cardiovascular disease. Because arterial inflammation is heightened in individuals living with HIV, we tested the hypothesis that SES associates with arterial inflammation in this population.SettingsProspective cohort study.MethodsMen living with HIV were recruited. Arterial inflammation and leukopoietic activity (ie, bone marrow activity) were measured using 18F-fluorodeoxyglucose positron emission tomography/computed tomography. Zip code-level SES measures were derived from the US Census Bureau. Linear regression and mediation analyses were used to assess associations between SES, arterial inflammation, leukopoietic activity, C-reactive protein (CRP), and interleukin-6.ResultsThirty-nine virologically suppressed men living with HIV were studied (mean ± SD age 50.5 ± 11.1 years). The median CD4 count was 663 cells/mm3 (interquartile range: 399-922); 82% were receiving antiretroviral therapies. Local median income inversely associated with arterial inflammation [standardized β (95% confidence interval): -0.42 (-0.76 to -0.08)] after adjusting for age, Framingham risk score, statin use, antiretroviral use, and nadir CD4 count. The high-school graduation rate independently associated with arterial inflammation [-0.45 (-0.78 to -0.12)] and CRP [-0.49 (-0.86 to -0.012)]. Mediation analysis demonstrated the impact of SES on arterial inflammation was partially mediated by heightened circulating inflammatory levels: ↓SES (as high school graduation rate) →↑CRP →↑arterial inflammation accounting for 44% of the total effect (P < 0.05).ConclusionIn individuals living with HIV, lower SES independently associated with higher leukopoietic activity, circulating markers of inflammation, and arterial inflammation. Furthermore, the link between SES and arterial inflammation was mediated by increased systemic inflammation.

Project description:We examined whether self-generated (status updates) or other-generated (wall-posts) information on Facebook influenced the impression formed of the target individual. Along with examining reliance on particular types of information, we explored the valence (positive/ neutral/ negative) of the information, as reliance on self-generated or other-generated information may depend on whether self-presentation is perceived (i.e., presenting oneself positively / not negatively). Self-presentation may be perceived if the targets have positive/ neutral statuses, while negative statuses would indicate a lack of self-presentation. In line with previous research, participants should rely on other-generated information (wall-posts) to form an impression when participants are viewed to have self-presented (positive / neutral status updates), as this information could be viewed as unreliable. Forty participants rated nine Facebook profiles where statuses and wall-posts portrayed personality traits varying in valence. Each profile consisted of a neutral profile photo, three status updates (all positive, negative, or neutral) and three wall-posts (all positive, negative, or neutral). Materials were established in two pilots. Impression formation was measured as perceived social, task, and physical attractiveness of the target individual. Participants also ranked the profiles for likeability. Supporting our expectations, other-generated information (wall-posts) dominated impression formation for social attractiveness when self-generated information (status updates) was positive/ neutral. Task attractiveness was affected by information valence, regardless of source (self or other). Despite the inclusion of neutral photos, physical attractiveness was affected by self-generated information, with negative statuses lowering physical attractiveness. We suggest that these findings have implications for impression formation beyond the Facebook setting. The 557 traits analyzed in Pilot 1 are available as supporting information (S1 Dataset) and may be useful for other impression formation researchers.
