Cuando las ratas tienen acceso a una solución azucarada al 32% y luego la concentración disminuye al 4%, los animales consumen o permanecen en contacto con el bebedero menos tiempo que los animales que siempre consumieron la solución al 4%. A este fenómeno de Contraste Sucesivo Negativo consumatorio (CSNc) se le considera un modelo animal de frustración. Existe evidencia de que en una prueba de luz-oscuridad, las ratas prefieren permanecer en el compartimiento oscuro, lo que sugiere una respuesta de miedo incondicionado hacia lugares claros. Se presentan dos experimentos en los que se evaluó la preferencia de ratas en una prueba de luz-oscuridad y a un CSNc (Experimento 1) y a una Extinción Consumatoria (Ec, acceso a un bebedero vacío, Expe...
