Basic needs fulfilment is fundamental to becoming human and reaching one's potential. Extending the BUCET list proposed by Susan Fiske - which includes belonging, understanding, control/competence, autonomy, self-enhancement, trust, purpose and life satisfaction - this book demonstrates that the fulfilment of basic needs predicts adult physical and mental health, as well as sociality and morality. The authors suggest that meeting basic needs in childhood vitally shapes one's trajectory for self-actualization, and that initiatives aimed at human wellbeing should include a greater emphasis on early childhood experience. Through contemporaneous and retrospective research in childhood, the authors argue that basic need-fulfilment is key to the development of the self and the possibility of reaching one's full potential. This book will be of interest to scholars of human wellbeing and societal flourishing, as well as to health workers and educators.
