Homo smartphonus: Psychological Aspects of Smartphone Use—A Literature Review

The increasing prevalence of smartphone use has raised concerns about its impact on human psychological functioning. This literature review provides a comprehensive overview of the psychological dimensions influenced by smartphone use, spanning health psychology, individual differences, social psychology, and cognitive functioning. The review draws on findings from numerous studies, primarily conducted in highly developed Western and Asian countries, where cultural factors may influence usage patterns and psychological outcomes. Key limitations in the current body of research include geographical biases and methodological challenges such as sample homogeneity and reliance on self-report measures. Evidence suggests that excessive smartphone use can lead to addiction and is associated with negative psychological and health consequences. The review also highlights how individual differences—such as personality traits, age, and gender—affect smartphone usage. Social implications, both positive (e.g., increased connectivity) and negative (e.g., interpersonal conflict), are explored in depth. Cognitive effects are considered, particularly in relation to attention and memory, where findings suggest potential impairments in sustained focus and information retention. While the literature often emphasizes risks, this review also points to the need for further exploration of the potential benefits of smartphone use. In summary, the review offers valuable insights into the complex psychological effects of smartphones and underscores the importance of future research to better understand their nuanced impact on well-being.
