Question

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.

Answer 1

This is a good example of signal detection theory or simply detection theory.

This theory indicates the ability we have to distinguish between different sounds. This ability is performed intentionally and allows us to perceive the distance from the origin of the sound. For that reason, Catherine can determinate where is their son. Likewise, our attention center reacts when listening to someone say our name, therefore her son will notice that his mother calls him.

I hope this information can help you.

Answer 2

The question above illustrates the signal detection theory. That is why Catherine can pinpoint the exact location when his son calls her.

 

EXPLANATION

The signal detection theory is the theory for the ability of a person to differentiate the information-bearing pattern and also other random patterns that can distract them from the information. There are several determiners that explain how someone can detect a specific signal, even though there are many distractions around them. The threshold levels of the signal are important.  

The signal detection theory believes that if the threshold of the signal is changed, then it will affect the ability to differentiate the signal. Human characteristics such as physiological state, experience, expectations, can affect the threshold that is applied. For example, if a person has physiological problems such as fatigue, then it will affect the threshold that is applied.  

There are works of detection theory. The researchers that did the work for detection theory were the radar researchers. This theory’s theoretical side was fully developed by Birdsall and Fox, also by Peterson.  

Meanwhile, the foundation of the signal detection theory was made by David M. Green, John A. Swets, and Wilson P. Tanner, in the year 1954. The signal detection theory is used in a lot of fields, such as telecommunications, psychology, and quality control. This concept is also used for alarm management, where it is important to differentiate the specific noise from other background noises.
