Multivariate Base Rates of Low Scores on Tests of Executive Functions in a Multi-Country Latin American Sample.

The objective of the study was to determine the prevalence of low scores in a diverse Latin American population for two neuropsychological commonly used tests to evaluate executive functions and to compare the number of low scores obtained using normative data from a Spanish-speaking population from Latin America versus an English-speaking population from U.S.A.

Regression-Based Normative Data for Children From Latin America: Phonological Verbal Fluency Letters M, R, and P.

This study is part of a larger project to generate norms for letter verbal fluency test (VFT) in 3,284 children from nine Latin American countries. The letter VFT (letters M, R, and P) was administered and multiple linear regressions, including age, age, MPE (mean parental education), MPE, sex, and interactions were used as predictors. Results showed significant differences across countries for all scores.

Newly developed Learning and Verbal Memory Test (TAMV-I): Normative data for Spanish-speaking pediatric population.

Objective: To generate normative data for the Learning and Verbal Memory Test (TAMV-I) in Spanish-speaking pediatric populations.

Method: The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the TAMV-I as part of a larger neuropsychological battery.

Symbol Digit Modalities Test: Normative data for Spanish-speaking pediatric population.

Objective: To generate normative data for the Symbol Digit Modalities Test (SDMT) in Spanish-speaking pediatric populations.

Method: The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the SDMT as part of a larger neuropsychological battery.

Modified Wisconsin Card Sorting Test (M-WCST): Normative data for Spanish-speaking pediatric population.

Objective: To generate normative data for the Modified Wisconsin Card Sorting Test (M-WCST) in Spanish-speaking pediatric populations.

Method: The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the M-WCST as part of a larger neuropsychological battery.
