This book focuses on the effects of phubbing by parents on their children, partners on their partners, bosses on their employees, friends on their friends, and family members on other family members. Having synthesised the findings from published research about the specific effects on these phubbed individuals in important relationships, the book then presents an exposition of the psychological predictors of phubbing (the triggers), followed by a broader account of the psychological effects of phubbing behaviour. The final chapter looks at the role of social norms in explaining the act of phubbing beyond the individual predictors that trigger the behaviour as it tries to draw a connection between phubbing and social theory.
