Step by step solution

01

Understand the options

Each of the options provided has a distinct meaning. Here are the definitions: \n\n a. Absolute threshold: This is the smallest level of stimulus that can be detected, usually defined as at least half the time. \n\nb. Difference threshold: This is the smallest amount by which a stimulus can be changed and the difference still be detected half of the time. Also known as Just Noticeable Difference (JND). \n\nc. Just noticeable difference (JND): This is the minimal change in a stimulus that can just barely be detected. \n\nd. Transduction: This is the process of converting one form of energy into another. In sensory processing, it refers to the conversion of sensory stimulus into a neural impulse.
