a set of systematic scientific procedures aimed at studying and understanding the level of development and function of the nervous system and related psychological functions, including cognitive, motor, emotional, language, and social abilities. These methods combine clinical data, standardized tests, direct observation, and interviews with parents and teachers to obtain a complete picture of a child’s abilities, strengths, and weaknesses. These methods include a general neurological assessment to examine sensory and motor functions; cognitive-psychological assessment to determine the level of attention, memory, thinking and problem solving; and an assessment of emotional and social functions to understand the child’s skills in managing emotions, social interaction, and self-regulation. These techniques also include a comprehensive analysis of information linking behavioral characteristics to neurological functions, which helps identify any developmental disorders or delays and develop individualized treatment and education programs. Such an assessment is characterized by scientific rigor and completeness, taking into account the individual and environmental differences of each child. This is an important step in providing effective interventions aimed at promoting neuropsychological development, improving learning and social adaptation, and supporting the integrated development of higher psychological functions.
