HyperSensory-Motofixation and the Induced Transient Neurodivergent-Like State: A Practitioner-Derived Framework for Velocity-Variable Visual Fixation, Autonomic Self-Regulation, and Digital Media

This paper introduces HyperSensory-Motofixation (HSM), a practitioner-derived construct describing a pattern of sustained, preferential visual fixation on velocity-variable motion that appears to serve autonomic self-regulation. The construct emerged from direct clinical practice in applied behavior analysis and from years of informal observation, and it is offered as a theoretical framework grounded in established neuroscience rather than as a validated empirical finding. HSM is defined by five converging features: the modality is visual, the stimulus is motion with velocity variation, the attentional quality is sustained and fixated, the function is autonomic and emotional regulation, and the intensity threshold is elevated. The paper situates HSM within the neuroscience of dorsal-stream motion processing, neural adaptation, and the magnocellular pathway, and it proposes a regulatory pathway linking visual motion processing to parasympathetic activation through several candidate mechanisms. It then examines the phenomenological overlap between HSM and the restricted and repetitive behaviors documented in autism spectrum disorder, arguing for a dimensional rather than categorical reading of sensory-regulatory fixation. Extending the framework to digital media, the paper advances the Induced Transient Neurodivergent-Like State (ITNLS) hypothesis, which holds that sustained engagement with vertical short-form video may produce a temporary and reversible constellation of features in neurotypical individuals that phenomenologically overlaps with autistic sensory processing. The paper closes with clinical implications and a falsifiable research agenda, including a single-subject reversal design with concurrent heart rate variability monitoring and a set of neuroimaging priorities. Both HSM and ITNLS are presented as testable hypotheses that await formal validation.
