Recall accuracy for speech-degraded short stories was assessed in young adults with normal hearing sensitivity. Stories were presented in the clear, or in noise vocoded, low-pass filtered, or background noise conditions of varying difficulty. Propositional scoring was used to determine the accuracy of participants’ recall. No significant effect on short story recall accuracy was observed for the degraded listening conditions. These results suggest that young adult listeners may be less susceptible to the extra cognitive challenge associated with degraded speech than might be predicted by the effortfulness hypothesis.
