The Value of the Lens Model Paradigm in Neuropsychological Assessment

Abstract

Abstract. A key issue of neuropsychological assessment is how to optimally associate mental function with neurobiological function. Correspondingly, clinical neuropsychology explores the relationship between mental dysfunction and neuropathology. Here, the well-known Brunswik-lens paradigm of psychological assessment is adapted to neuropsychology and a “neuro-lens model” (NLM) is suggested to better cross-link psychological and neurobiological construct domains. NLMs may contribute to optimizing coordinated measurement at different levels of aggregation and to clarifying issues of reliability and construct validation. Although the potential value of NLMs is challenged by complex implementation and analysis, Brunswik-type NLM modeling might be a promising new approach to clinical decision-making and assessment, test development, and research.
