The clusters were characterized by the following: (1) a visual processing deficit; (2) a generalized language disorder; and (3) a minimal deficit subtype. These subgroups were consistent with findings from previous investigations of subtypes of reading disability. The quality of the clusters was assessed through a series of evaluation techniques developed specifically for this purpose and through a cluster analysis of randomly generated data drawn from a normal distribution with the same covariance matrix as the actual data.

While the LNNB does not approximate Luria's approach, there are data to suggest that the battery may have potential as a quantitative, standardized battery. However, numerous substantial statistical and methodological problems with the research base preclude the endorsement of the battery for clinical use. Nevertheless, the efficacy of the LNNB in clinical situations will rest, not on the developer's and publisher's claims, or on detractor's critiques, but on carefully planned and well-executed research.

In order to foster more rational discussion of the topic, the present paper attempts to clarify major misconceptions regarding MBD, and reviews essential features of the concept. Because their term generates false impressions of the disorders to which it is applied and because the concept it represents is itself unsatisfactory, the continued use of the term is objectionable. Nevertheless, the emphasis that the MBD conceptor, more accurately, the tradition underlying it - has placed on biological factors as relevant to the understanding of learning and behavioral problems is worth retaining.
