Humans rely on the analysis of sensory input as an important source of knowledge about the world. Especially predicting the ‚when‘ of future events is crucial for successful interaction with our environment. How does the brain exploit the temporal structure of sensory information to predict upcoming events?
In this project we test the influence of rhythmic speech production on speech perception. Auditory perception has been shown to utilize temporal predictions from the motor system to increase its performance (Arnal, & Giraud, 2012; Merchant, & Yarrow, 2016).
For thousands of years people have admired the beauty of birdsong. But scientific understanding of this phenomenon is still restricted to studying learning and production mechanisms, as well as ecological function (how songs are used to attract mates and to defend territories). But what is it that makes a birdsong effective in attracting mates? What are the acoustic structures that are designed and able to engage a listener, and affect his or her emotional state?
To create a continuous conscious percept, our brain is concurrently carrying out multiple tasks: sampling sensory information, predicting upcoming events, storing long-term memories, maintaining and reactivating information from the past, etc. But how does the brain bind together these conscious and unconscious neural processes to give rise to a unified, but dynamical, subjective experience?
