Resumen
En el contraste sucesivo negativo consumatorio (CSNC), cuando las ratas reciben 32% de agua azucarada e imprevistamente son expuestas al 4% de la misma solución, consumen menos que las que siempre recibieron 4%, debido a un efecto de frustración. 38 ratas macho de la cepa Wistar se entrenaron en un CSNC y en un condicionamiento de lugar, usando inyecciones de etanol (0.5 g/kg) apareado a un contexto blanco (LB). Cuando la prueba de preferencia se realizó inmediatamente después de la devaluación del reforzador, las ratas frustradas que recibieron salina en ambos contextos prefirieron el contexto negro (LN). Esta tendencia se revirtió en los animales frustrados que recibieron etanol en el LB. Se consideran las implicancias teóricas y aplicadas de este hallazgo.
Following Consummatory Successive Negative Contrast (CSNC), when rats are given a 32% of sugared water and then unexpectedly exposed to a 4% of the solution, they drink less compared to the rats that always received the 4%, due to a frustration effect. 39 Wistar male rats were trained in two ways: in a CSNC and in a conditioned place, using ethanol injections (0.5 g/kg) paired to a white context (LB). When the test of preference was carried out immediately after the devaluated re-enforcer, the frustrated rats, which received saline in both contexts, preferred the black context (LN). This trend reverted in frustrated animals that received ethanol in the LB. Theoretical implications and applications of this finding are being considered.
