We conducted an EEG study where participants were given cues about the sharpness of upcoming sounds in a beat sequence. 🎧
Our goal: Understand how this predictive information influences brain activity and timing perception.
1) Enhanced Timing Precision: Participants showed improved accuracy (d-prime) in timing tasks when they had prior information about the sound's sharpness
2) Beta Band Activity (15–25 Hz): Before the target sound, beta power varied based on the predicted sharpness of the sound's envelope.
3) Cue-Reliability dynamics: Variations in cue reliability (due to the random nature of the experiment) were tracked by the brain and modulated the pre-target beta power
This research sheds light on how our brains use predictions about sound features to enhance temporal perception. Such mechanisms might be crucial for music and speech processing. 🎵
A big thank you to the entire team: Sabine Leske, Tor Endestad, Vegard Volehaugen, Maja D. Foldal, Anne-Kristin Solbakk & Anne Danielsen for their great work! 🙌
