AP PSYCHOLOGY

Detailed explanation-1: -In this case, a person is asked to listen to a series of tones presented in pairs, and asked to say whether the tones in each pair are the same or different in pitch. Therefore, the researcher is most likely measuring the individual’s difference threshold.

Detailed explanation-2: -A difference threshold is the minimum required difference between two stimuli for a person to notice change 50% of the time (and you already know where that “50% of the time” came from). The difference threshold is also called just noticeable difference, which translates the concept more clearly.

Detailed explanation-3: -Selective hearing is the ability to listen to a single speaker while in a crowded or loud environment. You might also hear it referred to as “selective auditory attention” or the “cocktail party effect.”

Detailed explanation-4: -This is because the brain receives signals from the nerves located in both ears and uses this information to process sounds. You may struggle to multi-task: Because of all of the above, single-sided deafness increases cognitive load on the brain, leading to listening fatigue.

Detailed explanation-5: -The cocktail party effect is the phenomenon of the brain’s ability to focus one’s auditory attention on a particular stimulus while filtering out a range of other stimuli, such as when a partygoer can focus on a single conversation in a noisy room.
