Abstract [en]

Cognitive abilities are important for a number of human attributes, such as making sense of communication, holding information active in memory, and making decisions. When it is the goal to focus on a single target voice, and resist intrusions from irrelevant information, cognitive inhibition can aid us in our endeavour. Cognitive inhibition is thought to support and co-operate with working memory. Abilities such as cognitive inhibition and working memory are also important for speech processing, even more so when listening to speech under adverse conditions. In order to assess different difficulties that can arise in every day listening situations, it´s of importance to have solid methods for measuring cognitive abilities. In the present study we present a task assessing cognitive inhibition, and how it relates to individual working memory capacity (WMC), and speech-recognition-in-noise. Forty-six young normally-hearing individuals were presented with a cognitive test battery, as well as a speech-in-noise test. Our results suggest that individuals with high WMC, also exhibit good cognitive inhibition. The results also indicate that those who perform well in the cognitive inhibition task need less favourable signal-to-noise-ratios in the speech-recognition task. Our findings indicate that capacity to resist semantic interference can be used to predict performance in speech-recognition tasks when listening under adverse conditions.
