Confiabilidad y validez de los instrumentos de evaluación neuropsicológica

the problem with psychological assessment in general and with that of cognitive functions in particular, presents methodological and transcultural challenges. instruments for assessing cognitive functions are not exempt from these difficulties. however, it would be interesting to refer to the similarities and differences regarding the approach of psychological assessment and that of the neuropsychological one. although the two types of assessments tend to propose diagnostic hypothesis, explain pathological behavior and enlighten on possible normal functioning, both include psychometrics in their methodology and therefore use valid and reliable instruments. the professional's knowledge of himself should encompass his roots and culture in order that he might be aware of the fact that his work is that of a "ser inserto en una cultura" (a being embedded in a certain culture), benet (1986, cited by renata frank de verthelyi).
