Resumen
Numerosos estudios en los últimos años, han constatado que la información novedosa se codifica como dependiente del contexto a partir de una modificación en el significado de otra clave (tratamiento de interferencia). Esto lleva a los sujetos a una situación de ambigüedad o incertidumbre produciéndose que se eleve la atención a toda la situación de aprendizaje lo que provoca que finalmente la nueva información se codifique como dependiente del contexto; este efecto es conocido como EMACS (Extinction Makes Acquisition Context Specific). El objetivo de este estudio fue evaluar si el efecto de cambio de contexto se atenúa, o incluso desaparece, conforme se consolida el aprendizaje de la extinción. Con este objetivo realizamos una tarea de aprendizaje predictivo humano en el que los participantes fueron asignados aleatoriamente a uno de tres grupos en los que y se manipuló la aparición o no de tratamiento de extinción (Grupos Extinción vs. Grupo Control), así como el momento en el que ocurrió el tratamiento de extinción: antes de la presentación de la nueva información (Extinción Inicio) o de manera concurrente a ésta (Extinción Final). Por último, se discuten los resultados en términos de las teorías sobre el control contextual.
Numerous studies in recent years have found that novel information is encoded as context dependent from a change in the meaning of another cue (interference treatment). This leads the subjects to a situation of ambiguity or uncertainty, causing attention to be raised to the entire learning situation, which ultimately causes the new information to be coded as context dependent; this effect is known as EMACS (Extinction Makes Acquisition Context Specific). The objective of this study was to evaluate if the context change effect is attenuated, or even disappears, as extinction learning is consolidated. With this objective, we carried out a human predictive learning task in which the participants were randomly assigned to one of three groups in which the appearance or not of extinction treatment was manipulated (Extinction Groups vs. Control Group), as well as the timing in which the extinction treatment occurred: before the presentation of the new information (Extinction Start) or concurrently to it (Final Extinction). Finally, the results are discussed in terms of theories contextual control.
