Final answer:
Thermoreception is the sensory modality that allows us to perceive temperature, including cold and warmth.
Step-by-step explanation:
When a person's cold receptors no longer convert cold sensory signals into electrical signals, that person has a problem with thermoreception. Thermoreception is the sensing of temperature, specifically cold and warmth. It is an important sensory modality that helps us regulate our body temperature and perceive the temperature of objects in our environment.
