BEYOND BRAIN DIFFERENCES: SOCIAL EXPERIENCES, ADAPTATION, AND PSYCHOSOCIAL WELL-BEING AMONG LEFT-HANDED INDIVIDUALS

Abstract

Left-handedness has traditionally been examined primarily through neuropsychological, developmental, and cognitive perspectives, whereas its social experience and adaptation to predominantly right-handed environments have received comparatively limited attention. This integrative literature review examines left-handedness through a person–environment perspective, focusing on the relationship between social experience, environmental demands, adaptation, and psychosocial well-being. Literature from psychology, neuroscience, education, ergonomics, sociology, and related fields was synthesised thematically to identify patterns in how left-handed individuals experience and negotiate family, educational, occupational, and everyday environments. Three interconnected themes emerged. First, the practical and psychosocial significance of left-handedness is strongly context-dependent: environmental organisation, cultural expectations, and interpersonal responses influence whether minority hand preference becomes socially consequential. Second, adaptation should not be treated as a unitary process. The synthesis distinguishes functional adaptation, characterised by relatively high individual agency and behavioural flexibility, from socially imposed hand modification aimed at conformity with right-handed norms. It further differentiates individual compensation from environmental accommodation as two pathways for reducing person–environment mismatch. Third, the reviewed evidence does not support a deterministic association between left-handedness and poorer cognitive or psychosocial functioning. Instead, environmental fit, social acceptance, autonomy, normative pressure, and opportunities for adaptation appear to constitute more meaningful explanatory factors. The review proposes an integrative person–environment model in which left-handedness represents an individual characteristic, social and material environments constitute the context of its expression, and adaptation mediates the relationship between environmental demands and psychosocial outcomes. This perspective shifts attention from correcting individual difference toward understanding and, where appropriate, modifying the environments in which that difference becomes consequential
