• The study examined the effect of feedback timing on the FRN and N170 ERP components in the context of feedback-based learning, by manipulating feedback timing and presenting auditory feedback. Previous studies reported that the FRN was modulated by feedback timing when feedback was visual. Additionally, the N170 ERP component was recently found to be sensitive to the timing of visual feedback (Arbel et al., 2017). The purpose of the present study was to elucidate the extent to which the FRN and N170 are modulated by feedback timing when feedback is auditory. Thirty healthy young adults were tasked with learning the names of 56 novel objects through trial-and-error guided by feedback in a two-choice paired association task. The 56 object-name pairs were divided into four sets, each containing fourteen items presented in five training blocks and a sixth testing block. In two of the sets auditory feedback was given 500 ms following a response, and in the two other sets feedback delivery was delayed by 6500 ms. The FRN was not found sensitive to the timing of the auditory feedback. However, sensitivity to timing was found in the N1-P2 complex preceding the FRN. The N170 was found sensitive to both feedback timing and valence, providing additional evidence to its relevance to feedback processing. Moreover, the elicitation of the N170 by auditory feedback suggests that the system that gives rise to the N170 in the context of processing delayed feedback is not unique to visual input. •FRN was found sensitive to the valence but not to the timing of the auditory feedback.•The N1-P2 complex was found sensitive to the timing of the auditory feedback with larger amplitudes for delayed feedback.•N170 was found to be modulated by feedback valence and timing, with larger amplitudes for delayed feedback.•N170 elicited in the context of delayed feedback may reflect MTL activation that is not limited to visual input.
