Brief Summary

Academic anxiety is one of the most prevalent psychological challenges among adolescents and has been associated with impaired executive functioning, attentional control, autonomic dysregulation, and reduced creative performance. Although neurofeedback and audiovisual entrainment have independently demonstrated beneficial effects on neural self-regulation, evidence regarding their integration within an adaptive closed-loop intervention remains limited. This multicenter, parallel-group, randomized controlled trial aims to evaluate the efficacy of an Audiovisual Entrainment Neurofeedback (AVE-NFB) system for improving neural self-regulation, reducing academic anxiety, enhancing autonomic regulation, and promoting divergent thinking among senior high school students. A total of 240 participants recruited from two school centers will be randomly allocated to one of four intervention groups: Combined AVE-Neurofeedback, Neurofeedback Only, Audiovisual Entrainment Only, or Sham Control. Each participant will complete 12 intervention sessions over a six-week intervention period (administered twice weekly). During every session, brain activity will be continuously acquired using the Emotiv Epoc X 14-channel research-grade electroencephalography (EEG) headset (256 Hz sampling rate). Following a standardized 5-minute resting calibration (3 minutes eyes closed and 2 minutes eyes open), the system will estimate each participant's individualized resting alpha activity (8-12 Hz). The neurofeedback engine continuously monitors alpha-band power from the multi-channel frontal (AF3, F7, F3, FC5, FC6, F4, F8, AF4) and temporoparietal (T7, P7, T8, P8) electrodes. Positive audiovisual reinforcement is automatically activated whenever the participant maintains alpha power above the individualized reinforcement threshold for at least 2 seconds while satisfying artifact-quality criteria. Reinforcement is automatically attenuated or suspended whenever alpha activity falls below the threshold or excessive ocular or motion artifacts are detected, thereby establishing a fully adaptive closed-loop reinforcement process based on operant conditioning principles. Outcome assessments will be performed at baseline, immediately after completion of the intervention, one week after the intervention, and one month after the intervention. Primary neural outcomes will include resting-state absolute alpha power measured using the Emotiv Epoc X 14-channel EEG. Secondary outcomes will include academic anxiety assessed using the Spielberger Test Anxiety Inventory (TAI), autonomic regulation assessed using Heart Rate Variability using the Root Mean Square of Successive Differences (RMSSD), and divergent thinking assessed using the Alternative Uses Task (AUT).

Outcome Measures

Primary Outcomes (1)

• Resting-State Alpha Power

  Measured via quantitative electroencephalography (qEEG) spectral analysis using the Emotiv Epoc X 14-channel research-grade EEG system from multi-channel frontal (AF3, F7, F3, FC5, FC6, F4, F8, AF4) and temporoparietal (T7, P7, T8, P8) regions of interest. Absolute alpha power is calculated within the 8-12 Hz frequency band during a 5-minute resting state (standardized 3-minute eyes-closed and 2-minute eyes-open calibration phase). The power is quantified in microvolts squared (µV²). An increase in absolute alpha-band power represents enhanced neural self-regulation and a state of relaxed alertness.

  Baseline, immediately post-intervention (Week 6), 1-week follow-up (Week 7), and 1-month follow-up (Week 10)

Study Arms (4)

Audiovisual Entrainment Neurofeedback (AVE-NFB)

EXPERIMENTAL

Participants will receive adaptive multimodal Audiovisual Entrainment Neurofeedback (AVE-NFB) integrating real-time EEG neurofeedback, heart rate variability (HRV)-guided adaptive thresholding, alpha-frequency photic stimulation, binaural beat auditory stimulation, non-directive relaxation guidance, and visual neurofeedback using the Emotiv Epoc X.

Device: Audiovisual Entrainment Neurofeedback (AVE-NFB)

Neurofeedback Only

EXPERIMENTAL

Participants will receive adaptive EEG-HRV neurofeedback using the Emotiv Epoc X EEG. Individualized alpha-band activity will provide real-time visual neurofeedback, while rolling HRV (RMSSD) estimates will dynamically adjust individualized reinforcement thresholds. No photic stimulation, binaural beat stimulation, or non-directive relaxation guidance will be delivered.

Device: Neurofeedback Only

Audiovisual Entrainment Only

EXPERIMENTAL

Participants will receive standardized alpha-frequency audiovisual entrainment consisting of rhythmic photic stimulation, binaural beat auditory stimulation, and non-directive relaxation guidance. The intervention will be delivered without EEG neurofeedback, HRV-guided adaptation, or individualized physiological feedback.

Behavioral: Audiovisual Entrainment

Sham Control

SHAM COMPARATOR

Participants will undergo a sham intervention using identical equipment, procedures, session duration, and environmental conditions as the active intervention groups. Although the EEG and HRV sensor will be attached, neither EEG nor HRV signals will influence the feedback provided. Any visual or audiovisual feedback will be pre-programmed and non-contingent on participants' physiological activity.

Behavioral: Sham Control

Interventions

Audiovisual Entrainment Neurofeedback (AVE-NFB) DEVICE

Participants will receive 12 Session of an Audiovisual Entrainment Neurofeedback (AVE-NFB) intervention integrating real-time electroencephalography (EEG) and heart rate variability (HRV) biofeedback. Neural activity will be continuously acquired using the Emotiv Epoc X EEG, while cardiac activity will be simultaneously recorded using Polar H10 for heart rate variability analysis. Individualized alpha-band activity (8-12 Hz) will serve as the primary real-time neurofeedback signal, whereas rolling Root Mean Square of Successive Differences (RMSSD) estimates will function as an adaptive physiological controller to dynamically adjust individualized reinforcement thresholds throughout training. Whenever alpha activity exceeds the adaptive threshold under acceptable signal-quality conditions, synchronized alpha-frequency photic stimulation, binaural beat auditory stimulation, non-directive relaxation guidance, and visual neurofeedback will be automatically delivered.

Audiovisual Entrainment Neurofeedback (AVE-NFB)

Neurofeedback Only DEVICE

Participants will receive adaptive EEG-HRV neurofeedback without audiovisual entrainment. Continuous EEG activity will provide the primary neurofeedback signal based on individualized alpha-band activity (8-12 Hz), while rolling RMSSD estimates will continuously optimize reinforcement thresholds throughout each session. Participants will receive real-time visual feedback contingent upon their ongoing neural activity. No rhythmic photic stimulation, binaural beat stimulation, or non-directive relaxation guidance will be administered. 12 intervention sessions will be completed over approximately six weeks.

Neurofeedback Only

Audiovisual Entrainment BEHAVIORAL

Participants will receive standardized alpha-frequency audiovisual entrainment consisting of rhythmic photic stimulation, binaural beat auditory stimulation, and standardized non-directive relaxation guidance. Stimulation parameters will remain fixed throughout each session without EEG acquisition, HRV biofeedback, individualized threshold adaptation, or brain-state-dependent reinforcement. Participants will complete 12 intervention sessions over approximately 6 weeks.

Audiovisual Entrainment Only

Sham Control BEHAVIORAL

Participants will undergo a sham intervention designed to replicate the appearance and procedures of the active interventions. The Emotiv Epoc X EEG and Polar H10 HRV sensor will be attached using identical preparation procedures; however, neither EEG activity nor HRV measurements will influence the audiovisual presentation or visual feedback. Any displayed feedback will be pre-programmed and non-contingent on participants' physiological activity. Session duration, operator interaction, and environmental conditions will be identical to those of the active intervention groups (12 sessions).
