King's Principle of Faulty Proprioceptive Input studied which population?

• A. Adults with process schizophrenia
• B. Children with autism
• C. Elderly with dementia
• D. Athletes with repetitive strain injury

Answer: (A)

This item centers on how proprioceptive processing may be altered in schizophrenia. Proprioception is the sense of body position and movement, and the idea here is that faulty proprioceptive input can contribute to the experiences and behaviors seen in adults with schizophrenia. When proprioceptive feedback is misinterpreted or unstable, it can affect body awareness, motor planning, and perception of the environment, which helps explain some of the disorganized or atypical responses seen in this population. As a result, the population studied under King’s principle is adults with schizophrenia.

The other groups aren’t the focus of this principle because the specific link being tested is between proprioceptive input processing and the symptom patterns associated with schizophrenia, rather than autism, dementia, or injuries related to repetitive strain.
