Session 2 provides neutral reactions (neutral gaze, “Hmm… I see”)

Session 3 provides negative reactions (tired facial expression, sighs, note-taking, whispering, corrective feedback such as “Please speak louder and more clearly”). Coping modules are 2 minutes each:

visual and auditory stimuli follow standardized scripts. Physiological data are recorded during exposure using photoplethysmography (ear-clip sensor) and galvanic skin response (index and middle finge
