The Performance Cascade™

One child. Four systems. Find where it starts.

Vision, posture, sensory regulation and attention work together. A classroom symptom is often where the breakdown shows, not where it begins. We look at vision first, then follow the chain.

  1. 1 · Start with vision

    Visual efficiency

    Pursuits, saccades, convergence and focusing at near. When these aren't automatic, near work costs more effort.

    Looks like: Loses place, rubs eyes, avoids copying

  2. 2 · Then check the body

    Posture and motor control

    The body adapts to help the eyes: head tilts, chin props, slumping, heavier pencil pressure.

    Looks like: Slumps, tilts head, writing falls apart

  3. 3 · Then regulation

    Sensory modulation and arousal

    Rising effort shows up as movement-seeking, chewing, or shutting down to keep going.

    Looks like: Rocks, chews, wanders, withdraws

  4. 4 · What the teacher sees

    Attention and task behavior

    Less capacity is left for starting, holding and finishing the task.

    Looks like: "Won't start," "off task," "looks like attention"

A clinical reasoning guide, not a diagnosis. The chain can start at any level; checking vision first keeps it from being missed.

Visual Performance System™

One clinical system for visual performance.

A child can pass an eye exam and still struggle to read, write, and pay attention. This system helps you find out why, and what to do about it – step by step.
