ABSTRACT
In order to perform a neuropsychologycal evaluation, the clinician may use several instruments; nevertheless, most of them have been designed for use on populations with very different social and cultural backgrounds from that of Mexico. This makes the research on the standardization of methods of evaluation for Mexican population a very important task for both clinical and research settings. Normative data obtained from Mexican population is necessary because it provides the clinician that works with Mexican patients with a reference framework that allows him or her to correctly classify a particular behavior of an individual as normal or abnormal and thus make specific evaluations and cooperate in diagnostic. Researchers interested on cognitive functioning also require qualitative and quantitative equivalent instruments that may allow them to objectively evaluate the efficacy of short-time interventions as in a pre- and post-treatment experimental designs; and it is precisely for this reason that Taylor's figure was developed. Taylor's figure (TF) was originally designed as an alternative to Rey-Osterrieth's complex figure (ROCF), in order to use it in test-retest situations. Similar to ROCF, Taylor's figure has two modalities: copy and memory. The former evaluates constructional praxia, while the latter measures immediate recalling. Parallel tests, that is, different tests that evaluate the same variables, are useful because they reduce the measurement error involved in applying the task twice to the same person (i.e. learning), thus increasing the validity of follow up evaluations of cognitive functioning. <
Dentro del ámbito neuropsicológico existe una serie de instrumentos de evaluación que en su mayoría han sido diseñados en un contexto sociocultural diferente al nuestro, por lo que es importante contar con pruebas neuropsicológicas estandarizadas en sujetos mexicanos. Desde esta perspectiva, los datos de una población normativa nos permiten tener un marco de referencia para comparar y establecer diagnósticos diferenciales dentro de la práctica clínica. Asimismo, dentro del ámbito de la investigación se requieren instrumentos que en teoría sean equivalentes en cuanto a la función que evalúan para llevar un seguimiento sobre el funcionamiento cognoscitivo de una población en particular a lo largo del tiempo. La Figura de Taylor se diseñó como una alternativa a la Figura Compleja de Rey-Osterrieth para aplicarla en situaciones de test-retest. Consta de dos modalidades: una de copia que evalúa la praxia de construcción y otra de memoria inmediata. El término <
