Catherine is at a crowded baseball game when she loses track of her son, Nick. Despite the loud cheering and noise of the crowd, she can pinpoint his location when he calls for her because she can distinguish the sound of his voice from the all the other voices. This illustrates theory.

1.signal detection
2.absolute threshold
3.sensory adaptation
4.just noticeable difference

The correct answer to the following question will be Option 1 (Signal Detection).

Explanation:

The concept or theory of signal detection, which is at its quite simple, states whether detection of something like a stimulus rests both on the strength of that same stimulus as well as the person's physiological/mental issue.Whether the sound would be a spontaneous variable with such an established spectrum of probabilities, then maybe this information can be used to find the best way of identifying the signal.

The other three options are not related to the given scenario. So, Option 1 is the right answer.

The answer should be a.
