Try looking up each of the answers on Google.

The correct answer to the question is b. Signal detection theory of sound and sleep.

To understand why it is the correct answer, let's examine each option:

a. Selective attention: Selective attention refers to the ability to focus on a specific stimulus while filtering out other irrelevant stimuli. In this case, the residents of Cordele, Georgia are not actively choosing to ignore the train whistles; they are simply unable to hear them due to their habituation.

b. Signal detection theory of sound and sleep: Signal detection theory suggests that our ability to detect a stimulus depends on both the intensity of the stimulus and the individual's sensitivity to it. In this scenario, the residents have become desensitized to the sound of the train whistles due to repeated exposure, thus resulting in them not waking up or being aware of the noise during their sleep.

c. Sensory adaptation: Sensory adaptation refers to the decline in sensitivity to a constant stimulus over time. While the residents may have initially been sensitive to the train whistles, their repeated exposure has caused them to adapt and become less responsive to the sound.

d. Cocktail party phenomenon: The cocktail party phenomenon refers to the ability to focus on a specific stimulus, such as a conversation, amidst multiple other competing stimuli. It is not applicable to this scenario as the residents are not consciously choosing to focus on other sounds and ignore the train whistles.

Therefore, the best answer is b. Signal detection theory of sound and sleep, as it explains how the residents' lack of awareness of the train whistles during sleep is due to the habituation or desensitization caused by repeated exposure to the sound.
