Based on existing research on social networking and information seeking, it was proposed that Facebook.com use could be conceptualized as serving two primary goals: passive social browsing (i.e., newsfeeds) and extractive social searching (i.e., friends' profiles). This study explored whether these categories adequately reflect Facebook use and whether they moderate physiological indicators of emotion. Thirty-six participants navigated Facebook.com while their on-screen activity and physiological responses associated with motivation and emotion were recorded. Results showed that the majority of screens encountered during Facebook use could be categorized as devoted to social browsing or social searching. Participants spent more time on social browsing than they spent on social searching. Skin-conductance data indicated that sympathetic activation diminished during the course of both social browsing and social searching. Facial EMG data indicated that participants experienced more pleasantness during the course of social searching than they experienced during social browsing. These results are discussed in terms of existing social-networking research and an evaluative space model of emotion.

Background: Although evening screen time is thought to impair subsequent sleep, current measures are limited to questionnaires which seem unlikely to accurately assess screen time in youth. Given the ubiquitous nature of digital devices, improving measurement of screen time is required before related health effects can be appropriately determined. The aim of this study was to objectively quantify screen time before sleep using video camera footage.

Associations between screen time and mental health may be driven by increased use in young people with heightened symptoms as a means of modifying negative mood. However, the direct effect of technology use on mood remains unclear. This study aimed to investigate the effect of active and passive social media use on an induced sad or neutral mood by randomising young people (16-24 years; N = 116) to a sad or neutral mood induction task and assessing mood after being instructed to engage in active or passive social media use.

Unlabelled: Public discourse and empirical studies have predominantly focused on the negative repercussions of social media on adolescents' mental health. However, pervasive social media use is a relatively new phenomenon-its apparent harms have been widely accepted before sufficient longitudinal and experimental research has been conducted. The present study used an intensive longitudinal design (four assessments/day × 14 days; = 154 12- to 15-year-olds ( = 13.

Accessing the Internet is one of the most frequent free-time activities among autistic and non-autistic adolescents. Autistic individuals may experience communicative benefits from using the Internet. However, they may also be at risk of developing Problematic Social Media Use (PSMU).
