Question

The initial approach to measuring individual differences in sensation was the use of absolute thresholds. In the 21st century, researchers use a more sophisticated approach that takes an observer's response bias into account. This approach is termed _____ theory.

Answer 1

Step-by-step explanation:

According to this theory, there are a number of factors that determine how a system will detect a signal and the point at which the threshold level will be pinpointed. E.g. in humans factors such as fatigue, experience, expectations can affect the applied threshold.
