Which of the following statements is associated with King's Principle of Faulty Proprioceptive Input?

• A. Increased sociability
• B. Lack of motivation
• C. Enhanced executive function
• D. Rapid motor movements

Answer: (B)

Proprioceptive input helps regulate arousal and drive to engage in activity. When there’s faulty proprioceptive processing, a child can show under-arousal and difficulty initiating or maintaining engagement, which manifests as reduced motivation. This is what King’s Principle of Faulty Proprioceptive Input describes, making lack of motivation the best fit among the options.

Increased sociability isn’t typically tied to proprioceptive dysfunction in this framework, as it would imply a social approach pattern rather than a sensory regulation issue. Enhanced executive function reflects higher-level cognitive skills not directly linked to proprioceptive fault in this principle. Rapid motor movements suggest hyperactivity or motor disinhibition, whereas faulty proprioceptive input often results in under-responsivity or sluggish initiation rather than quick, jerky movements.
