En el desarrollo de esta tesis se estudió la manipulación de diferentes mecanismos fisiológicos implicados en la captación o pérdida de agua del sapo común Rhinella arenarum con el fin de encontrar diferentes reforzadores que pudieran ser aplicados en protocolos de aprendizaje instrumental. En primer lugar, se verificó que los sapos aprenden a encontrar agua deionizada (reforzador apetitivo) localizada en una posición fija con respecto a su cuerpo (a la derecha o a la izquierda) y que dependiendo de la osmolaridad externa de la solución ésta puede ser aversiva (pierden peso), neutra (no ganan ni pierden peso) o apetitiva (ganan peso) produciendo cambios en el comportamiento de animales parcialmente deshidratados (alejamiento, cuando están e...
