Speech and gestures
Basil Preisig, Noëmi Eggenberger
In healthy subjects, both verbal (speech) and nonverbal (facial expressions, gestures, body posture etc.) elements contribute to human communication. Gesturing, including co-speech gestures, is a particularly crucial part of human communication.
It is uncertain to which extent aphasia, an acquired loss or impairment of language functions influences gesture production and / or perception. We are studying gesture comprehension and production in a series of experiments while controlling limb apraxia, an oftentimes concomitant higher cognitive motor deficit.
