Quantitative Analysis of Taylor Figure in Mexican Population from 20 to 60 Years Old

摘要

The high prevalence of neurological disorders in Mexico and the need to accommodate them within the process of clinical evaluation requires neuropsychological instruments adapted to the population. Without doubt, this purpose implies essentially the standardization as common practice in research activity. Taylor's figure was designed as an alternative to Rey-Osterrieth complex figure to apply it in situations of test-retest, but so far its quantitative properties in the Mexican adult population have not been studied. With this objective in mind, test was applied to a sample consisting of 300 Mexican adults aged between 20 and 60 years. The analysis showed a high discriminative power of the reagents within copy modality (p< 0.001) and memory (p< 0.001), and a reliability of the 0.79 and 0.78 respectively. Scores distribution in the sample shows a normality pattern exists in both modalities. It was obtained as well deterioration and increase in efficiency and execution times respectively, in both categories as increased the age range. These results can be explained from the slowing of cognitive processing theory (Cerella, 1985;) Salthouse, 1996).
