Revisiting Social Value Orientations and Environmental Attitude-Identity-Intention in Decomposed Games

Understanding food waste sorting behavior in institutional food services: An integrated psychological framework

Food waste from institutional food services accounts for a significant part of global food waste. Food waste sorting (FWS) at the source reduces waste management costs and environmental impacts in organizations. Yet what drives individual FWS behavior remains underexplored. This study explores the psychological process of FWS in institutional catering environments, integrating the value-belief-norm model, the theory of planned behavior, and self-determination theory. Data were collected from 431 university students in China and analyzed using partial least squares structural equation modeling (PLS-SEM). Results indicated the interplay of values, beliefs, norms, and motivations in shaping FWS behaviors. Social value orientations (SVO) indirectly affected FWS through awareness of consequences and personal norms. Subjective norms, potentially attributed to external regulations in canteens, influenced FWS intention through personal norms and induced FWS primarily via controlled motivations. The findings imply that behavioral strategies to induce FWS may leverage social influence and external regulation while also translating values and knowledge into intrinsic motivations through educational programs and awareness campaigns.

The Role of Social Value Orientation in Chinese Adolescents' Moral Emotion Attribution

Previous studies have explored the role of cognitive factors and sympathy in children's development of moral emotion attribution, but the effect of personal dispositional factors on adolescents' moral emotion expectancy has been neglected. In this study, we address this issue by testing adolescents' moral emotion attribution with different social value orientation (SVO). Eight hundred and eighty Chinese adolescents were classified into proselfs, prosocials and mixed types in SVO and asked to indicate their moral emotions in four moral contexts (prosocial, antisocial, failing to act prosocially (FAP) and resisting antisocial impulse (RAI)). The findings revealed an obvious contextual effect in adolescents' moral emotion attribution and the effect depends on SVO. Prosocials evaluated more positively than proselfs and mixed types in the prosocial and RAI contexts, but proselfs evaluated more positively than prosocials and mixed types in the antisocial and FAP contexts. The findings indicate that individual differences of adolescents' moral emotion attribution have roots in their social value orientation, and suggest the role of dispositional factors in the processing of moral emotion.
