Nardi's self-described theoretical orientation is "activity theory", a philosophical framework developed by the Russian psychologists Vygotsky, Luria, Leont'ev, and their students.
It is similar to other neuropsychological frameworks, including Alexander Luria's cultural-historical psychology and psychological activity theory, but also draws from disciplines such as speech-language pathology, occupational therapy, and physical therapy.
