Science-Based: The Sensory Seeking vs. Sensory Overload Loop

Science-Based: The Sensory Seeking vs. Sensory Overload Loop — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

A detailed, research-grounded visual explaining the internal tug-of-war between an ADHD brain craving high-stimulation, novel environments and an autistic nervous system needing predictable, lower-sensory environments.

This infographic covers:

• ADHD-related novelty/reward-seeking signals (dopamine/reward, curiosity, movement, novelty, stimulation-seeking) vs. autistic sensory overload/autonomic strain signals (sensory load, unpredictability, noise/light overload, rising autonomic arousal, shutdown risk)
• The two drives: seeking/stimulation drive (novelty and reward seeking, craving intensity) vs. overload/protection drive (sensory sensitivity, need for predictability, retreat/freeze/shutdown)
• Six-stage loop: under-stimulated/seeking → high-interest environment → engagement spikes → sensory load builds → autistic nervous system overloads → crash/retreat/recover — then renewed seeking
• What it can look like: craving busy places then suddenly needing to leave, asking for more stimulation then melting down, restlessness and impulsive choices followed by shutdown
• Why it gets misread: seen as attention-seeking or contradictory; overload may be blamed on behaviour instead of nervous-system load; support may be withheld because the seeking part is more visible than the crash
• What actually helps: balance stimulation with predictable recovery time, use structured novelty (interest with boundaries), watch body cues not just behaviour, reduce sensory load before the crash point, support regulation first
• Grounded in peer-reviewed review literature on co-occurring ADHD and autism, sensory processing, executive function, and autonomic regulation
