Awareness and differential eyeblink conditioning: effects of manipulating auditory CS frequencies

Abstract

The role of awareness in differential delay eyeblink conditioning (EBC) has been a topic of much debate. We tested the idea that awareness is required for differential delay EBC when two cues are perceptually similar. The present study manipulated frequencies of auditory conditioned stimuli (CS) to vary CS similarity in three groups of participants. Our findings indicate that awareness was not necessary for differential delay EBC when two tones are easily discriminable, awareness was also not needed for relatively similar tones but may facilitate earlier conditioning, and awareness alone was not sufficient for differential delay EBC.

Caracterización de los tipos de respuesta de parpadeo en un procedimiento de condicionamiento discriminativo en humanos

“…Luego de varios ensayos, emerge una RC de parpadeo al tono. Se podría decir aquí que las personas aprenden al menos dos cosas (Shanks, 2010;Weidemann, Tangen, Lovibond, & Mitchell, 2009): la primera es información declarativa acerca de la relación predictiva entre el tono y el soplo de aire (Bolaram Coe, Power, & Cheng, 2020;Lovibond, Liu, Weidemann, & Mitchell, 2011;Weidemann, Satkunarajah, & Lovibond, 2016). La segunda es información no declarativa y consiste en la emisión de una RC de parpadeo (Schade Powers, Coburn-Litvak, & Evinger, 2010).…”
