Normative Data of Neuropsychological Tests of Attention in Older Adults from Costa Rica

To generate normative data for the Trail Making Test (TMT) and the Target Cancellation Task for healthy older adults in Costa Rica.563 healthy Costa Rican adults aged 59-90 years (M = 67.15; SD = 7) were assessed. Each participant was administered the two attention tests as part of a more comprehensive neuropsychological battery.Multiple regression models showed a linear effect of education for TMT-A and TMT-B, as well as a linear and curvilinear effect of age for TMT-B and TMT-A, respectively. The model predictors explained between 27.4% and 30.3% of the variance. For the Target Cancellation Task scores, linear effects of education were observed for all 4 scores, as well as a linear effect of age for the TMX time and Rhombus time scores. The correct TMX score showed a curvilinear effect of age. The predictors of the model explained between 2% and 33.3% of the variance.This is the first normative data generated for the TMT and the Target Cancellation Task in older adults from Costa Rica. This normative data will be used in individuals with a variety of neurological conditions that course with attention deficits to establish the neuropsychological profile of those individuals in this area.
