The scientific explanation for this is that Jay and Gerard have different _____ thresholds.a) differenceb) Weber’sc) standardd) absolute

Answer 1

Answer:The scientific explanation for this is that Jay and Gerard have different ABSOLUTE thresholds.

Explanation:

An absolute threshold refers to the minimun level of stimulus that a person is able to detect at least half the time.

This refers to how one will use their senses to detect that stimulus such as touch , taste, sight , smell and sound.

When you are given different levels of sound volume the smallest volume that you are able to hear is your absolute threshold. This happens 50 percent of the time meaning half the time because not all the time you are able to detect such level of sound or when you are able to feel the slightest touch.

Gerald and Jay then have different ABSOLUTE thresholds Jay seems to have a very strong or sharp or high absolute threshold of touch because he is able to detect the slightest touch whilst Gerald can't detect the slightest touch.
