Healthy, male subjects aged 18 to 35 years

Subjects must be in good general health

Refrain from alcohol/smoking/caffeine/drugs 24 hrs before the experiment

Refrained from food/drinks (except water) and intensive exercise two hours before the administration of oxytocin

E.5 End points
E.5.1Primary end point(s)
Level of eye gaze from participant towards the eye area of the physician.

Levels of participants’ trust in the physician.

E.5.1.1Timepoint(s) of evaluation of this end point
Level of eye gaze: during the first video session and during the second video session.

Levels of participants’ trust: after the first video session and after the second video session.
E.5.2Secondary end point(s)
Satisfaction with the physician: Measured with a visual analogue scale (VAS) ranging from 0 (not likely at all) to 100 (most likely) asking “I would recommend this doctor to a friend or family member.”

Pupillometry: The measurement of pupil size and reactivity (dilation and restriction), measured with the Tobii screen eye tracker.

Satisfaction with the doctors’ communication style: Measured with the Doctor Communication Style items (translated to Dutch with forward-backward translation) on two subscales: affiliativeness and dominance/activity. Items are answered on a 5-point Likert Scale from “strongly agree” to “strongly disagree”.

Recall & Recognition (of information as explained during the medical communication video): Questionnaire which assesses participants’ level of free recall and recognition of information provided by the videotaped physician. The questionnaire will be designed based on the information provided in the video.
