What are the Luria's methods and theories

Adhering to our theory that the Luria Nebraska bears little resemblance to Luria's methods and theories, there seems little point in inspecting the theoretical basis for the substance of the Luria Nebraska battery. For instance, there is little point in examining the theory of language that underlies the Receptive Speech and Expressive Speech scales or the theory of memory that gives the basis for the Memory scale. We believe that the Luria Nebraska battery is not a means of using Luria's theory and methods in English speaking countries, but rather a standardised psychometric instrument with established validity for particular purposes and reliability
