Episode notes
Movement Can Be An Attention Tool
- Hyperactivity and inattention often co-occur, and teachers frequently adapt informally by allowing movement breaks.
- Small allowances like bathroom breaks can function as sensory resets that aid attention.
Structure Background Input To Free Attention
- Structuring background sensory input (white noise, familiar TV) helps the brain partition relevant from irrelevant channels.
- Familiar, predictable stimuli reduce competition for attention and make target tasks easier to focus on.
Neutralize Salient Sensory Distractions
- Identify and reduce personally salient sensory distractors like textures, light, or temperature.
- If unavoidable, introduce predictable background stimuli to create redundancy and reduce salience.
