Resumen

Se realizó un experimento en condicionamiento instrumental humano con el objetivo de evaluar los mecanismos subyacentes al efecto de cambio de contexto sobre una clave de significado no ambiguo cuando los contextos son informativos para solucionar la tarea. Se entrenó a los participantes en una discriminación inversa basada en el contexto en la que debían discriminar entre dos claves (X e Y) que intercambiaban sus significados entre los contextos A y B. En el contexto A se presentó además el estímulo discriminativo Z anunciando consistentemente una relación entre una respuesta instrumental concreta (R1) y una consecuencia determinada (O1). La respuesta en presencia de la clave Z durante la prueba empeoró cuando la prueba se realizó fuera del contexto de entrenamiento, independientemente de si el contexto de prueba era un contexto familiar para el participante (contexto B) o un contexto nuevo (contexto C). Estos resultados son consistentes con la idea de que los participantes codifican toda la información presentada en contextos informativos como dependiente de contexto, con el contexto jugando un papel similar al de un estímulo modulador.
