Question

A quality inspector at the local manufacturing plant carefully examines a product for flaws using a special light. The flaws show up as dark green spots of light. For this inspector, the ___________ is the point at which a flaw can be detected.

a. Threshold of perception
b. Absolute threshold
c. Just noticeable difference
d. Threshold of discrimination

Answer 1

The absolute threshold is the point at which a flaw can be detected. It refers to the minimum amount of stimulus energy required to be detected 50% of the time.

Step-by-step explanation:

The correct answer is a. Absolute threshold. The absolute threshold refers to the minimum amount of stimulus energy required to be detected 50% of the time. In the context of the quality inspector examining a product for flaws, the absolute threshold is the point at which a flaw can be detected using the special light. This means that the flaw will be visible as dark green spots of light once the stimulus energy reaches the minimum required level.
