Discuss the "thresholds" theory of classical psychophysics and explain how this perspective has been modified by the advances of signal detection theory
What will be an ideal response?
Classical psychophysics basically says that if a stimulus has enough intensity to cross our absolute threshold (which is the minimal amount of a stimulus necessary for detection), it will be sensed. Signal detection theory claims that the perceiver's physical condition, judgments, and biases also play a role in signal detection.
