Toward a clinical procedure for narrowband gap detection I: a psychophysical procedure

This paper examines a possible procedure for a clinical gap-detection test that is simple, frequency specific, and reliable. A cued yes-no method of maximum likelihood (MML) procedure was compared to an up-down three-interval, two-alternative, forced-choice procedure. Results from five trained and seven naive listeners indicate that the yes-no MML procedure yields valid and efficient estimates of narrowband gap-detection thresholds. Preliminary tests yield encouraging results.
