Resumen
Antecedentes: en este estudio se evaluó el efecto de la duración del entrenamiento instrumental sobre la conducta de búsqueda de alcohol en ratas. La investigación actual sugiere que la formación de hábitos E-R es responsable de la búsqueda compulsiva de la droga que caracteriza a las conductas adictivas. Método: se entrenó a las ratas a realizar una respuesta instrumental con etanol como recompensa. Los sujetos recibieron 2 sesiones de entrenamiento en el primer experimento y 2, 8 o 16 sesiones en el segundo estudio. Tras devaluar el etanol con LiCl se estimó la tasa de respuesta de los animales en extinción. Resultados: el efecto de la devaluación del reforzador sobre la conducta instrumental dependió del número de sesiones de entrenamiento recibidas; la tasa de respuesta disminuyó tras un entrenamiento moderado (2 y 8 sesiones) pero no se vio afectada con un entrenamiento más prolongado (16 sesiones). Conclusiones: los resultados sugieren que la búsqueda de alcohol depende del valor reforzante de la droga en la fase inicial de desarrollo de la adicción pero se vuelve rígida y automática (hábito) con la experiencia repetida.
