B the signal-detection theory of sound and sleep
C - we adapt to sounds that are repetitive around us
The correct answer is C, sensory adaptation.
Sensory adaptation is the process by which our sensitivity to a constant or repetitive sensory stimulus decreases over time. It allows us to ignore or become less aware of stimuli that remain constant or repeated, such as the sound of passing trains.
In this scenario, the residents of Cordele can sleep through the train whistles because their auditory system has adapted to the continuous presence of the sound. Over time, their brains adjust and become less responsive to the repeated auditory stimulus of the train whistles. As a result, they can sleep undisturbed despite the noise.
On the other hand, the signal-detection theory of sound and sleep (option B) explains how factors like individual thresholds and the importance of the stimulus influence our ability to detect and respond to sounds during sleep. While it is relevant to understanding our perception of sound while sleeping, it is not specifically applicable to this scenario.
The "cocktail party phenomenon" (option D) refers to our ability to selectively focus on a particular auditory stimulus while filtering out other sounds in a noisy environment. While this concept is related to attention and sound processing, it is not directly relevant to explaining how the residents of Cordele can sleep through the train whistles.
Therefore, the correct answer is C, sensory adaptation.
