MORE ABOUT PSYCHOMETRY: QUALITATIVE SYNDROMIC ANALYSIS IN A CASE OF SEVERE APHASIA DUE TO CEREBROVASCULAR DAMAGE
Abstract
In neuropsychological diagnosis, there are two approaches that can be characterized as psychometric neuropsychology and qualitative neuropsychology, depending on the emphasis each one places on how difficulties are assessed during task performance. Psychometric neuropsychology focuses on quantifying correct or incorrect responses, and in some cases, a small numerical scale is assigned to performance (0, 1, 2). In qualitative neuropsychology, the emphasis is on analyzing the nature of errors and identifying under what conditions of activity regulation task performance improves or worsens. Qualitative analysis should be understood as a flexible and systematic process that allows for the diagnosis of alterations in the organization of psychological activity and provides insight for its reorganization. The objective of this study is to describe the syndromic analysis process in a case of ischemic stroke whose severity made it impossible to use psychometric tests or standardized protocols. A single-case observational design was used. The results made it possible to identify the syndrome of sequential motor organization, according to the model of A.R. Luria. The systemic effect of the primary defect on the patient's verbal activity is presented. The study concludes that qualitative analysis of signs and symptoms leads to an accurate diagnosis, thus laying the groundwork for the reorganization of the impaired functional systems.
