Effects of Cueing in Auditory Temporal Masking.
Purpose: In a landmark study, B. A. Wright et al. (1997) reported an apparent backward-masking deficit in language-learning-impaired children. Subsequently, the controversial interpretation of those results has been influential in guiding treatments for childhood language problems. This study revisi...

A. Wright et al. (1997) reported an apparent backward-masking deficit in language-learning-impaired children. Subsequently, the controversial interpretation of those results has been influential in guiding treatments for childhood language problems. This study revisited the temporal-masking paradigm reported by B. A. Wright et al. to evaluate adult listener signal/masker uncertainty effects for some of their key stimulus conditions. New signal conditions presented off frequency from the masker also were evaluated to assess conditions of reduced signal/masker confusion. Method: Masked detection was measured for 20-ms sinusoids (480, 1000, or 1680 Hz) presented at temporal positions before, during, or after a gated narrowband (bandwidth = 600-1400 Hz) masker. Listener uncertainty was investigated by cueing various stimulus temporal properties with a 6000-Hz sinusoid presented contralateral to the test ear. Results: The primary cueing effect was measured in the backward-masking condition for the cue gated simultaneously with the on-frequency 1000-Hz signal. The resulting cued masked-detection threshold was reduced to quiet threshold. No significant cueing effects were obtained for other signal temporal positions in the masker or for any off-frequency signal conditions. Conclusions: These results for normal adult listeners indicate that on-frequency backward masking can be eliminated by cueing the signal, and thus, these findings raise the possibility that the deficit reported by B. A. Wright et al. for language-learning-impaired children may reflect inordinate signal/masker confusion, rather than a temporal-processing deficit per se.
