Beyond Accuracy: Cognitive Speed in Speech-in-Noise Processing and Its Implications for the Ease of Language Understanding Model

Key Points

• The aim is to explore the relationship between cognitive speed and speech-in-noise processing, particularly how it affects language understanding.
• Analyzed the relationship between cognitive speed and speech-in-noise processing.
• Examined the role of working memory speed and executive speed.
• Assessed the predictive ability of executive speed on rapid automatized naming (RAN).
• Cognitive speed is linked to speech-in-noise (SPIN) processing and the ease of language understanding (ELU) model.
• Executive speed can predict RAN performance effectively.
• SPIN serves as a potential early indicator of cognitive decline.
