st- BLC 4182_PSY_110 J110_1687 https://elearning.kctcs.edu/weba ing Time: 59 minutes, 46 seconds. n Completion Status: Raj asked his 13 year old to turn down the televesion. After 10 minutes he told his teen "Hey I told you to turn that down - please lower the volume." His teenager said that they already did the first time they were asked. Raj's failure to detect that the volume had been lowered is due to his: o a.Just Noticable Difference Threshold o b. Absolute Threshold o c. Sensory Adaptation o d. Similarity

Explanation / Answer

the answer is

A; JUST NOTICABLE DIFFERENCE THRESHOLD

-This branch of psychology is focused on sense, sensation, and perception. In this, there is only little bit difference. It is the minimum level of stimulation that a person can detect. For the person to detect something the difference between the stimulation should be 50%. . If a light is very, very dim, people might be more likely to notice smaller changes in intensity than they would if those same changes were made to a brighter light

Hence raj could not detect the lowered volume because there can only be a small amount of change in the volume and he could not have detected it.
