The methodological problems of correlation (or compliance) and quality metric assessments in neuropsychology

This article highlights the strengths and weaknesses of to two research directions neuropsychology of domestic and foreign, as well as identifying possible areas of integration. One of the most acute problems is the development of experimental psychological methods to determine the quantitative and expressed characteristics of the psychic phenomena by flexibly combining qualitative and quantitative approaches, with a view to putting into practice foreign neuroscience principles and standards of evidence. An analysis of contemporary publications on neuropsychological diagnosis reveals the need to consider the standardization of neuropsychological research in the context of current approaches, requirements, and psychodiagnostic criteria. In the domestic neuropsychological literature, these issues are need attention: standardized procedures for presenting stimuli are not, as a rule, described; basic psychometric assessment of the results of the tests is lacking; no investigation of their clinical and psychometric validity is carried out. An analysis was made of the nature of the psychometric approach in foreign child neuropsychology, which relies on mathematical procedures of processing qualitative (ordinal) data converted into quantitative indicators. We examined separately the mathematical software for clinical trials (based on the principles of «evidence-based medicine« which relies on the «abnormal» nature of the distribution of clinical phenomena.
