We applied the Stereotype Content Model to examine whether the use of different types of portable display devices during a simulated video-conferencing consultation between two actor-clinicians differentially affected perceptions of clinician warmth (operationalised as perceived politeness, engagement and trustworthiness). Across three experiments (combined <i>N</i> = 745) we found that clinicians using head-worn displays are perceived as warmer than those using tablets. This effect was not moderated by the frequency (low <i>vs.</i> high) or type of interruptions (work-related <i>vs.</i> social) that occurred during the consultation.

Thirty participants completed the HPT, with performance assessed via response time and two signal detection theory indicators (sensitivity and response bias). Results show that higher speeds shorten HP response times, which seemingly indicates improved HP; however, their negative impact on sensitivity and response bias suggests reduced accuracy and cautiousness in the HP process.

Subjective assessments included the Robotic Social Attributes Scale (RoSAS) and self-report, while physiological responses were measured using electrocardiogram (ECG), galvanic skin response (GSR) and eye-tracking. Results showed that robot-like faces and human-like voices were linked to more positive perceptions, while human-like faces and beeping sounds led to greater negative emotional responses. Physiologically, both beeping sound and human-like voices increased skin conductance, and human-like voices also raised heart rate variability (HRV), suggesting participants felt less stressed under human-like voice conditions.
