Question

The minimal stimulus necessary for detection is called the ________, while the smallest noticeable change in a stimulus is referred to as ________.

Answer 1

The minimal stimulus necessary for detection is called the absolute threshold, while the smallest noticeable change in a stimulus is referred to as difference threshold.

Answer 2

The minimal stimulus necessary for detection is called the absolute threshold, while the smallest noticeable change in a stimulus is referred to as difference threshold. This minimal stimulus (absolute threshold) is the minimum intensity required for a person to sense it. The difference threshold on the other hand is the amount of difference needed to notice a change between two things.
