The threshold model assumes that there is a fixed threshold for detecting a signal and that noise can interfere with detection. The signal detection theory adds the concepts of discrimination and bias to account for individual differences in the ability to discriminate between signal and noise and the criteria used to make a decision. Discrimination refers to an individual's ability to distinguish between signals and noise, whereas bias refers to the individual's tendency to say "yes" or "no" even when the signal is not present.
