Hypothesis: Frontal Theta Neurofeedback + Exercise Can Restore Executive Control in Short-Form Video Users
Background
A 2024 study (Frontiers in Human Neuroscience) found that short-form video addiction (TikTok-style content) correlates with reduced frontal theta power during executive control tasks and impaired self-control. The neural deficit is specific: decreased theta oscillations in prefrontal regions during cognitive conflict.
Hypothesis
In adolescents/young adults with problematic short-form video use, a precision intervention combining frontal-midline theta neurofeedback with aerobic exercise will produce superior restoration of executive control compared to either intervention alone or standard CBT.
Rationale (Deep Research via BIOS)
Targeting the specific deficit:
- Short-form video users show reduced frontal theta during conflict tasks
- Frontal-midline theta neurofeedback produces long-term improvements in working memory and conflict monitoring
- This directly addresses the identified neural mechanism
Why combine with exercise:
- Physical exercise significantly reduces internet addiction severity and improves self-control (large effect size)
- Exercise enhances neuroplasticity and BDNF expression
- Could amplify neural reorganization induced by neurofeedback
Precision medicine angle:
- Resting-state theta power predicts neurofeedback training success
- Baseline theta assessment could stratify treatment response
- Personalize intervention intensity to neural phenotype
Current Evidence Gaps
- CBT is the gold standard for digital addiction (SMD = -1.9) but doesn't target the specific neural deficit
- No studies have combined neurofeedback + exercise for digital addiction
- Pharmacological approaches lack evidence and aren't first-line
- Policy interventions (platform design changes) show promise but large-scale evidence is inconclusive
Novelty
First to propose:
- Using frontal theta deficit as a predictive biomarker to stratify treatment
- Combining theta neurofeedback with exercise to exploit synergistic neuroplasticity
- Transforming digital addiction treatment from one-size-fits-all CBT to mechanism-targeted neuromodulation
Testable Predictions
Primary endpoint: Change in Flanker task conflict effect (RT incongruent-congruent) and frontal theta power (Fz, 4-8 Hz) at 10 weeks
Expected results:
- Combined intervention > either alone > CBT control
- Baseline theta stratification predicts response magnitude
- Molecular mediators: BDNF, dopamine receptor expression changes
Research Design
4-arm RCT (n=120): (1) theta neurofeedback, (2) aerobic exercise, (3) combined, (4) group CBT control. Stratify by baseline resting frontal theta power. Measure EEG during cognitive tasks, self-report addiction scales, objective screen time monitoring.
