 While both occupational science and occupational therapy are rooted in systems theory and holistic views of human agency, the methods for observing and understanding an occupation's form (how something is done), function (its purpose), and meaning (how it is understood by the doer) are not always holistic in approach.For instance, disciplines such as biomechanics and psychology inform occupational science but, individually, are not necessarily concerned about how their explanations contribute to an integrated understanding of the factors influencing of a person's daily life .Professional practice in occupational therapy can prompt new ideas and spark potential research within the discipline of occupational science; although typically, knowledge from academic disciplines precedes the application of such knowledge in applied fields.
