Final answer:
The interthreshold range refers to the range of sensory stimuli that elicit a response. This range can be explored through two-point discrimination tests for pressure receptors and thermoreception for temperature receptors.
Step-by-step explanation:
The interthreshold range refers to a. Range of sensory stimuli that elicit a response. This concept is crucial in understanding how sensory systems operate, especially in determining the limits of sensory perception for different stimuli. The concept of interthreshold range can be studied through various types of sensory tests, including those for pressure receptors using the two-point discrimination test and for temperature receptors via thermoreception. The concept of the absolute threshold, which is the minimum amount of stimulus energy required to be detected 50% of the time, also feeds into this exploration of sensory stimulation and perception.
