Journal Article
Wadsley, M., & Ihssen, N. (2023). Restricting social networking site use for one week produces varied effects on mood but does not increase explicit or implicit desires to use SNSs: Findings from an ecological momentary assessment study. PLoS ONE, 18(11), Article e0293467. https://doi.org/10.1371/journal.pone.0293467

Recent research on the addictive potential of modern technologies such as the internet, smartphones, or social networking sites (SNSs) has suggested that emotional and motivational changes associated with the sudden discontinuation of engagement with...

Despite growing concerns about the addictive potential of social networking sites (SNSs), little is known about the precise neural, cognitive, and emotional processes underpinning compulsive SNS behaviours, such as excessive checking of SNSs. Recent... Read More about The roles of implicit approach motivation and explicit reward in excessive and problematic use of social networking sites.

The Predictive Utility of Reward-Based Motives Underlying Excessive and Problematic Social Networking Site Use (2021)
Journal Article
Wadsley, M., Covey, J., & Ihssen, N. (2022). The Predictive Utility of Reward-Based Motives Underlying Excessive and Problematic Social Networking Site Use. Psychological Reports, 125(5), 2485-2516. https://doi.org/10.1177/00332941211025271

Compulsive seeking of reward is a hallmark feature of drug addiction, but the role of reward is less well understood in behavioural addictions. The present study investigated the predictive utility of ten reward-based motives, which we identified in...
