Study Summary

This trial will focus on understanding how the frequency-following response, a scalp-recorded neurophonic potential, is influenced by stimulus context, arousal state, and category relevance in neurotypical human participants.

Who is the study for?
This trial is for English or Mandarin speakers aged 13-25 with normal hearing and less than six years of music training. It's not for those with hearing loss, tinnitus, cognitive impairments, trouble understanding speech in noise, or proficiency in languages other than English/Chinese.Check my eligibility
What is being tested?
The study investigates how the brain responds to sounds and language using a neurophonic potential called FFR. It looks at how predictability, relevance of sound categories, and arousal state influence this response in healthy individuals.See study design
What are the potential side effects?
Since the interventions involve non-invasive sound stimulation without drugs or medical procedures, significant side effects are not expected. Participants may experience fatigue or discomfort from wearing headphones or scalp electrodes.
