The document discusses several basic psychophysical procedures used to study threshold detection and discrimination in tactile signals: 1. The yes-no procedure judges presence or absence of a signal and analyzes results using receiver operating characteristic (ROC) curves. 2. Forced-choice procedures measure the proportion of correct responses between signal trials and catch trials which can be converted to d-prime sensitivity measures. 3. Confidence rating and same-different procedures examine how observers discriminate between intensities or identities of stimuli. 4. Adaptive tracking methods like forced-choice tracking and transformed response methods efficiently estimate thresholds by adjusting stimulus levels run-to-run based on observer performance.
