Social media use has previously been shown to have negative implications for cognition. Scarce research has examined underlying pathways through which social media use may influence cognition. One potential pathway involves the consequences of social comparison, such that those who use social media more frequently may feel worse about themselves and more envious toward others. In turn, these negative socioemotional states could compromise memory. Further, whether an individual uses social media actively or passively may moderate these associations. Using an online adult lifespan sample (n=592), the current cross-sectional study examined whether socioemotional consequences of social comparison (self-esteem and envy) mediated relationships between social media use and memory (everyday memory failures and episodic memory) and whether active/passive use moderated these associations. Mediation models revealed that higher envy, but not lower self-esteem, partially explained the relationship between higher social media use and more self-reported everyday memory failures. Neither envy nor self-esteem mediated the relationship between higher social media use and lower objective episodic memory performance. Additionally, higher social media use was associated with higher envy to a greater extent for active users compared to passive users. These findings may suggest that high social media use has negative ramifications for both subjective and objective memory and that increased feelings of envy may partially explain these effects for subjective, but not objective, memory.

Frequent use of highly visual online platforms such as Instagram may be linked to greater body image concerns. One prominent feature of Instagram is the ability to receive feedback in the form of likes and comments. The goal of this cross-sectional study (conducted in laboratory and online) was to examine college students' receipt of appearance commentary on their most recent Instagram posts, and how this relates to their self-reported body image concerns. The Instagram commentary that 337 students (M _age=20.39) received on their posts was observationally coded for positivity and negativity. Receiving positive appearance commentary was common and linked to greater appearance-related social media consciousness, and, weakly, to body surveillance. There were no associations with self-objectification, appearance-contingent self-worth, facial satisfaction, and body dissatisfaction. Negative appearance commentary was not associated with body image concerns. Photos depicting only the self were especially likely to elicit positive appearance commentary. Females received more positive appearance commentary compared to males, whereas males received more negative appearance commentary. Future research should examine long-term effects of receiving appearance comments via Instagram.

Sharing "selfies" on social media is common among adolescents. The frequency with which adolescents post selfies may be less important than behaviors and cognitions underlying selfie-posting, and these practices may differ by gender. This multi-method study explored selfie practices in a school-based sample of 639 adolescents (M _age=17.6; 53.5% female). Participants completed self-report measures of selfie practices, body esteem, depressive symptoms, and peer behaviors. In addition, a subset of participants' social media pages (n = 245) were observationally-coded for numbers of selfies, followers, and likes. Factor analyses revealed two distinct selfie practices: selfie appearance investment and selfie peer feedback concern. Girls posted selfies more frequently, and reported greater levels of appearance investment and concern over peer feedback on selfies compared to boys. Multiple group structural equation models indicated that for boys and girls, selfie appearance investment was associated with depressive symptoms. For girls only, selfie peer feedback concern was associated with excessive reassurance-seeking and lower body esteem. No associations were revealed between observationally-coded measures of selfie-posting frequency and psychosocial outcomes. Overall, findings suggest that frequency of selfie-posting may be less relevant for understanding adolescent adjustment than investment in and concern over the selfie-posting experience.
