Pseudohypacusis reflects an overly conservative response criterion under signal detection theory.

Evidence

For patients with bilateral pseudohypacusis, the audiologist must make modifications to the audiometric procedures in order to determine true absolute thresholds. The procedures in place were specifically designed in order to encourage patients to provide a neutral or liberal criterion. However, in the cases of pseudohypacusis, these practices have not achieved that goal. To obtain a more accurate audiologic threshold, the audiologist essentially applies the principles of Signal Detection Theory to encourage the patient to adopt a more neutral or liberal criterion. Consequently, the first step in audiometric testing for patients with suspected pseudohypacusis is to re-instruct the patient. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1766
