when kevin started his car in the parking lot, he also turned on the radio to his favorite station. as he enetered the street next to the campus, he turned the radio up due to the increased background noise in the car. entering the highway, he again increased the volume until he could hear the music clearly. driving into the driveway at home, he saw his mother watering her roses in the front yard. "Kevin! Turn down that radio. We are going to be deaf before you are twenty five!" she instructed as he open the car door. he had not noticed how very loud the radio was until she mentioned it. Kevin had experienced

a. absolute threshold constancy
b. weber's law
c. sensory adaption
d. sensory deprivation

Is it A? any other opinions please

I'm not sure -- but the best answer looks like this --

C is right.

Based on the given scenario, the correct answer is c. sensory adaption.

Sensory adaptation refers to the process in which our sensory receptors become less sensitive to constant or repetitive stimuli over time. In this case, when Kevin started his car, he turned on the radio and initially adjusted the volume to a comfortable level. However, as he entered different environments with varying background noise levels, he gradually increased the volume to ensure he could hear the music clearly. This suggests that Kevin's auditory system adapted to the new levels of background noise, causing him to perceive the original volume as relatively quieter until his mother pointed it out.

Absolute threshold constancy refers to the minimum level of a stimulus required to detect it consistently. Weber's law relates to the just noticeable difference (JND) between two stimuli being proportional to the magnitude of the original stimulus. Sensory deprivation, on the other hand, refers to a lack of normal sensory stimulation. None of these concepts directly apply to Kevin's situation in the given scenario.

Therefore, the most appropriate answer is c. sensory adaption.
