Explain the Principle of Development

The final guiding principle is that assessment involves the measure of change, or development, across multiple levels of analysis. Developmental neuroscience has highlighted the multiple processes that characterise brain development. For example the cell differentiation and migration, the dendritic behavioural and pruning as well as the timing of these processes. Although less research has been conducted concerning developmental changes in children's environment, there is nevertheless a natural history of environment that is characteristic of most children in a culture. Behavioural development in turn can be conceptualised as the result of the joint interplay of these biological and environmental time tables and is characterised by the emergence, stabilisation and maintenance of new scales as well as the loss of earlier ones. The neuropsychological assessment therefore requires appreciation for the developmental changes that occur in brain, behaviour and context because the interplay between these levels of analysis determines adaptation outcomes.
