El objetivo del presente trabajo fue demostrar el efecto de recuperación espontánea en humanos empleando una tarea de nado virtual similar a la piscina de Morris. Se presentan dos experimentos con una tarea de aprendizaje espacial de nado virtual (VSL Nesplora©). En el primer experimento los participantes aprendieron a localizar la plataforma de salida que se ubicó entre los puntos de referencia que formaron los objetos A y B en 8 ensayos. En el experimento dos, a dos grupos se les presentó la tarea espacial del experimento anterior, durante la primera fase la plataforma se ubicó entre los objetos A y B, mientras que durante la segunda entre C y D, ambas fases constaron de 12 ensayos. Se realizó una prueba con los cuatro objetos presentes y sin la plataforma, un grupo a las 0h y al segundo 24h después. Los resultados mostraron que cuando la prueba se realiza a las 0h la búsqueda de la plataforma se realiza en base a los puntos de referencia C y D pero a las 24h se observa una elección intermedia entre A-B y C-D. El modelo experimental presentado es contrastado con los estudios de aprendizaje espacial en animales que han observado efectos asociativos.
The aim of present study was to demonstrate spontaneous recovery effect in humans using a swimming virtual task analog to Morris pool. Two experiments with a task of spatial learning of swim virtually (VSL Nesplora ©) are presented. In the first experiment the participants learned to locate in 8 trials the exit platform that was located between the points of reference that formed the objects A and B. In Experiment 2, the spatial task of the previous experiment was presented to two groups, but during the first phase the platform was located between objects A and B, whereas during the second one it was located between C and D; both phases consisted of 12 trials. A test was performed with the four objects present and without the platform, a group at 0h and the second one 24h later. The results showed that when the test was made at 0h, platform searching is based on landmarks C and D, but when the test was made at 24h an intermediate choice between landmarks AB and CD was observed. The experimental model presented is contrasted with the studies of spatial learning in animals where associative effects have been observed.
