As recent results encourage the inclusion of speech in noise (SIN) testing as part of a routine hearing screening test (Arlinger, Lunner, Lyxell, & Pichora-Fuller, 2009), we need to understand exactly which abilities SIN tests are actually indexing. In this study, we investigated the effect of top-down support on speech-in-noi-se perception and the influence of cognitive ability on this relationship by using monosyllabic words presented with stationary background noise in an adaptive threshold procedure. Participants with normal-hearing had to identify (Condition 1) or recognize (Conditions 2 and 3) a target word in noise in descending (Conditions 1 and 3) or ascending (Condition 2) levels of difficulty. Cognitive ability was measured using the reading span and letter memory tests. The results showed a significant effect of top-down support on speech in noise perception thresholds. The magnitude of this effect was predicted by performance on the letter memory test, indicating that good updating ability is, in presence of top-down support, a good predictor of speech in noise perception, in accordance with the Ease of Language Understanding model (Rönnberg, Rudner, Foo, & Lunner, 2008; Rönnberg, 2003; Stenfelt & Rönnberg, 2009). The results of the study highlight the importance of considering that non-auditory factors may play a significant role in speech-in-noise perception. The degree to which non-auditory factors influence speech-in-noise perception is affected by both the test procedure chosen and the cognitive ability of the listener.
