Title: Re: Discuss the "thresholds" theory of classical psychophysics and explain how this Post by: ThePsychic on May 26, 2012 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.
