Which statement best reflects the role of inner drive in Ayres' sensory integration theory?

• A. It is irrelevant
• B. It depends solely on external rewards
• C. It is a minor factor
• D. It is an intrinsic inner drive that motivates participation in sensorimotor activities

Answer: (D)

Inner drive in Ayres' sensory integration theory is an intrinsic motivation that propels a child to actively participate in sensorimotor experiences. This inner push comes from the child’s own need to organize sensory input through purposeful movement and exploration, guiding engagement in activities that stimulate vestibular, proprioceptive, and tactile systems. When this inner motivation is present, the child seeks out and sustains sensorimotor challenges, which supports efficient sensory integration and adaptive behavior. It’s not about external rewards or pressure, and it isn’t an insignificant or irrelevant factor—self-driven exploration is central to how Ayres envisioned the brain organizes sensation through meaningful, hands-on activity.
