Review of modern foreign research on the problems of left-handedness

Context and relevance. Left-handedness as a characteristic of individual typological characteristics of a person. Statistical data on the prevalence of left-handedness. The causes of left-handedness are genetic, pathological, and acquired. Objective. To show the connection of left-handedness with psychomotor and emotional characteristics, with deterioration of mental health and quality of life. Hypothesis. Due to atypical laterality, left-handed children have a complex of significant features of the bioelectric activity of the brain, as a result of which the cognitive, volitional and emotional spheres of left-handed children are characterized by an unstable level of arbitrary regulation. Results. The revealed psychological and pedagogical features of left-handed children show that they differ from their right-handed peers in mental development due to the presence of certain features of intelligence and specific thinking strategies, methods of memorization and the specifics of emotional and affective expression. Conclusions. Understanding the possible connection between left-handedness and psychological difficulties is of great importance for parents, educators, and mental health professionals, as it allows them to timely notice developmental features, provide necessary support, and create favorable conditions for the adaptation and well-being of left-handed children.
