Researchers at Zhejiang University conducted a study using fMRI and magnetic resonance spectroscopy to monitor how short-form video consumption affects brain activity in 56 young adults. The findings indicated decreased activity in the dorsal anterior cingulate cortex (dACC) and the dorsolateral prefrontal cortex (dlPFC), regions associated with decision-making and cognitive control.

Subsequent reports expanded on these findings, noting that the deactivation of these regions may impact self-control, logic, and planning. Dr. Allison Hensley, a pediatrician at Loma Linda University Children’s Health, noted that the rapid pacing of algorithmic feeds may create a “dopamine-driven reward loop similar to substance abuse,” which could potentially hinder a child’s ability to maintain focus and deep learning.
