Which option is NOT listed as one of the five physical signals and their perceptual modalities?

• A. Temperature change
• B. Light (vision)
• C. Air vibrations (audition)
• D. Body position (kinesthetics/proprioception)

Answer: (A)

The essential idea is how physical energy forms map to our perceptual senses in a standard five-signal framework. In that framework, light is recognized as the signal for vision, airborne vibrations are heard as audition, and body position is sensed as kinesthetics/proprioception. Temperature change, while a real sensory channel (thermoreception), is not included in this particular five-signal list, so it isn’t listed among the five signals in this context. That’s why temperature change is the correct choice for the one that isn’t part of the set.
