Brain Engagement Score

A Brain Engagement Score (BES) is a composite metric that predicts the intensity and quality of neural activation across key brain regions during video viewing. It aggregates predicted responses from attention networks, emotional processing regions, and memory-encoding circuits into a single score.

Unlike surface engagement metrics (views, likes, shares), a brain engagement score measures what's happening inside the viewer's brain — not their behavioral response. This distinction matters because neural engagement is often a better predictor of downstream outcomes (brand recall, purchase intent, behavior change) than surface metrics alone.

VidCognition's Brain Engagement Score is derived from TRIBE v2 predictions across multiple cortical regions, including:

• Attention networks: Fronto-parietal regions that control sustained attention
• Visual processing areas: V1–V5 and higher visual cortex
• Emotional processing: Amygdala and limbic system activation
• Memory encoding: Hippocampal activation associated with long-term memory formation

A high BES (70+) indicates the video is producing strong, broad neural activation — the kind associated with deep processing and recall. A low BES indicates passive processing or disengagement — the viewer may watch but won't remember.

BES is most useful when analyzed at the second level — identifying which moments of a video produce peak engagement and which moments cause neural disengagement, even before viewers swipe.
