The purpose of this study is to conduct a theoretical exploration into the conceptual interrelationships among information processing, psychosocial adjustment, and sensory processing in the population of gifted youth. Although researchers have now been studying various aspects of giftedness for almost a century, many controversies persist with regard to the psychological functioning of gifted children and adolescents. The aim of this study is to develop more conceptual clarity regarding information processing, psychosocial adjustment, and sensory processing in gifted youth to contribute to the understanding of how these constructs manifest themselves and bear upon the phenomenology of giftedness. This will involve a creative integration of theory and research across various disciplines, including psychology, medicine, and occupational therapy. Four major areas of conceptualization are included: social and emotional characteristics of gifted youth, psychosocial adjustment of gifted youth, processing and intelligence, and processing and temperament.
