This randomized controlled trial investigated the effects of Alpha-band neurofeedback (NFB) on children with Autism Spectrum Disorder (ASD). The study involved 40 participants and found that NFB training led to significant improvements in social cognition and relating skills, alongside notable physiological changes in EEG, including a steepening of the aperiodic slope and enhanced periodic alpha power.
Key findings
- NFB training resulted in significant behavioral improvements in social cognition and relating skills.
- The experimental group showed a significant steepening of the aperiodic slope, indicating reduced neural noise.
- Periodic alpha power increased, and the alpha center frequency accelerated, suggesting improved neural efficiency.
Why it matters
Understanding the neurophysiological mechanisms underlying interventions like neurofeedback can enhance treatment strategies for children with ASD. Improved behavioral outcomes linked to EEG changes may inform future therapeutic approaches.
