Neural computations of episodic memory processing of speech and song
In this research area we investigate the cognitive and neural mechanisms underlying the episodic memory for speech and song. Speech and song are fundamental forms of human vocal behavior. Although they have many commonalities, song shows characteristics of music such as its rhythmic and melodic structure that differentiates it from speech. Interestingly, an episodic memory advantage for recalling verbal content has been suggested when listening to song compared to speech. The mechanisms underlying this effect and its neural underpinnings, however, are still unknown. The rhythmic temporal structure and melodic pitch information in song vs. speech may lead to the recruiting of differential neural circuitry, which in turn aid the memorization of song. We apply behavioral, neuroimaging and computational modeling approaches to investigate the role of rhythmic (with a focus on auditory motor processing) and melodic processing in forming episodic memory representations.
