WebJan 31, 2024 · From the perspective of signal detection theory, in an acceptability judgment experiment, there are two types of stimuli and two possible decisions 4. This creates four logical combinations. If the stimulus is predicted as acceptable by a linguistic theory and is judged as acceptable, it is a hit (i.e., true positive).
