When Ann went to her doctor, he gave her a hearing test. During the test, the doctor presented tones to Ann through earphones. The tones varied only along the loud-soft dimensions (from very loud to very soft) . The doctor asked Ann to raise her hand whenever she heard a sound. The doctor was testing Ann's _______.
A) auditory convergence
B) refractory threshold
C) absolute threshold
D) difference threshold
Absolute Threshold
The smallest intensity of a stimulus that can be detected by the senses at least 50% of the time.
Auditory Convergence
The coordination and integration of sound signals from both ears in the brain, contributing to the localization and understanding of sound.
Refractory Threshold
The minimum duration needed after an action potential initiation during which another action potential cannot be triggered in a neuron.
- Recognize and elucidate critical notions in sensation, including absolute threshold, difference threshold, and the function of receptor cells.
- Acknowledge the importance of sensory thresholds in sensing environmental stimuli.

Final Answer :
C
Explanation :
The doctor was presenting tones to Ann in order to determine her ability to perceive the softest sound, which is known as the absolute threshold. The other options (auditory convergence, refractory threshold, and difference threshold) are not relevant to this particular hearing test.
