Determining Sensory Thresholds:
This is the threshold at which the intensity of a sensory stimulus can be perceived by the patient – referred to as ‘psychophysiological’ – the psychological interpretation of a physiological stimulus many variables influence the subjective interpretation.
1) Threshold method:
• clinician gradually increases stimulus and patient reports threshold at which they feel it
• very subjective high number of false high and false low thresholds
2) Yes/No method:
• patient asked to report if a stimulus was applied or not after clinician asks them for a response
• clinicians includes ‘null’ trials
• still very subjective as patient must interpret if stimulus perceived
3) Forced-choice method:
• eliminate a lot of the subjectivity
