Abstract

Acoustic and phonemic information form the basis for speech perception. We used confidence reports to examine the extent to which 1) both representations contributed to identification performance, 2) whether participants had an awareness of acoustic information, and 3) whether confidence reports were influenced by both acoustic and phonemic representations in an identification task. Our results suggest that participants’ response were primarily guided by explicit, phonemic information. We also found that an interpolation between typicality ratings and identification functions yielded an excellent fit to the function produced by confidence reports suggesting that confidence processing.
