What is modulation in sensory integration?

• A. The brain's ability to regulate and filter sensory information.
• B. An overestimation of sensory input during movement.
• C. A method for increasing heart rate variability during therapy.
• D. A cognitive strategy for memory recall.

Answer: (A)

Modulation in sensory integration refers to the brain’s ability to regulate and filter sensory input so responses stay adaptive. It involves adjusting the amount, timing, and salience of incoming sensations to maintain an optimal arousal level for functioning, learning, and participation. This means helping someone stay calmly engaged when there’s a lot of sensory information or, conversely, providing enough input to prevent under-responsiveness. In hippotherapy, the therapist can tailor the sensory experiences—such as rhythm, pressure, and movement—to support this regulatory process, promoting more organized, appropriate responses.

That’s why the best description is the brain’s capacity to regulate and filter sensory information. The other options describe specific outcomes or unrelated strategies (perceptual overestimation, heart rate variability methods, or memory recall strategies) rather than the regulatory process at the heart of sensory integration modulation.
