Semantic verbal fluency of animals: a normative and predictive study in a Spanish population.

Semantic verbal fluency is a very sensible but rather unspecific tool for the detection of neuropsychological deficits. This test is highly influenced by socio-cultural factors. Normative and predictive data for semantic verbal fluency of animals in a Spanish population are presented. The studied sample (n = 445) was stratified according to age and schooling. Statistical analysis reconfirmed a significant negative correlation (- 5.34) for age, and a significant positive correlation (5.34) for years of formal education. A predictive function for the production of names of animals during 1 min was established based on the subject's age and level of education: F(x) = 23.89 + age (- .144) + education (.39). The neuropsychological value and limitations of normative data and the predictive equation are discussed.
