a complex and interrelated set of characteristics that reflect the development of the child’s brain and nervous system and the impact of these physiological processes on psychological, cognitive, emotional and behavioral development. This concept includes the study of the relationship between neurobiological and physiological factors that regulate higher brain functions, such as attention, memory, thinking, and emotional regulation, and the psychological and behavioral characteristics exhibited by children at different stages of development. This concept emphasizes that neuropsychological development is not a linear or discrete process, but depends on the continuous interaction of neurophysiological abilities with the psychological and social experiences surrounding the child, resulting in the formation of complex behaviors and psychological cognitive functions that change and develop over time. It is also emphasized that understanding these characteristics allows therapists and educators to develop educational and therapeutic interventions that take into account the individual characteristics of each child and contribute to the comprehensive development of higher psychological functions, including cognitive learning, emotional regulation and the ability to adapt to the environment in a balanced and sustainable way.
