“…Indeed, previous studies in the field of experimental psychology confer the benefits of using interactive virtual environments to simulate and test the impact of environments or situations that are difficult to study. [28][29][30] In addition, we also confirmed that youth thought our virtual store was a realistic representation of convenience stores that they frequent. Despite these strengths, our study has some potential limitations.…”

OBJECTIVE: To examine the potential impact of banning tobacco displays and ads at the point of sale (POS) on youth outcomes. METHODS: An interactive virtual convenience store was created with scenarios in which the tobacco product display at the POS was either openly visible (status quo) or enclosed behind a cabinet (display ban), and tobacco ads in the store were either present or absent. A national convenience sample of 1216 youth aged 13 to 17 who were either smokers or nonsmokers susceptible to smoking participated in the study. Youth were randomized to 1 of 6 virtual store conditions and given a shopping task to complete in the virtual store. During the shopping task, we tracked youth’s attempts to purchase tobacco products. Subsequently, youth completed a survey that assessed their perceptions about the virtual store and perceptions about the ease of buying cigarettes from the virtual store. RESULTS: Compared with youth in the status quo condition, youth in the display ban condition were less aware that tobacco products were for sale (32.0% vs 85.2%) and significantly less likely to try purchasing tobacco products in the virtual store (odds ratio = 0.30, 95% confidence interval = 0.13−0.67, P < .001). Banning ads had minimal impact on youth’s purchase attempts. CONCLUSIONS: Policies that ban tobacco product displays at the POS may help reduce youth smoking by deterring youth from purchasing tobacco products at retail stores.

We present the findings of a quantitative and qualitative empirical research to understand the possibilities of engagement and affection in the use of conversational agents (chatbots). Based on an experiment with 13 participants, we explored on one hand the correlation between the user expectation, user experience and intended use and, on the other, whether users feel keen and engaged in having a personal, empathic relation with an intelligent system like chatbots. We used psychological questionnaires to semi-structured interviews for disentangle the meaning of the interaction. In particular, the personal psychological background of participants was found critical while the experience itself allowed them to imagine new possible relations with chatbots. Our results show some insights on how people understand and empathize with future interactions with conversational agents and other non-visual interfaces.

“…In a review paper, Cook and Triola (2009) concluded that virtual patients ''are likely to play an increasing role in medical education in coming years.'' Another promising application for virtual humans is assessment of interpersonal competency skills in inner-city adolescents and prisoners (Hubal et al, 2008).…”

One of the most common methods of inducing stress in the laboratory in order to examine the stress response in healthy and clinical populations is the Trier Social Stress Test (TSST). Briefly, the participant is asked to deliver a speech and to perform an arithmetic task in front of an evaluating committee. The committee, consisting of three trained actors, does not respond emotionally during the test, which makes the situation very stressful for the participant. One disadvantage of the TSST is that it can be difficult to hold the experimental conditions constant. In particular, it may be difficult for actors to hold their acting constant across all sessions. Furthermore, there are several practical problems and costs associated with hiring professional actors. A computerized version of the TSST using virtual humans could be a way to avoid these problems provided that it is able to induce a stress response similar to the one of the original TSST. The purpose of the present pilot study was therefore to investigate the stress response to a virtual reality (VR) version of the TSST visualized using an immersive VR system (VR-TSST).Seven healthy males with an average age of 24 years (range: 23-26 years) performed the VR-TSST. This included delivering a speech and performing an arithmetic task in front of an evaluating committee consisting of three virtual humans. The VR equipment was a CAVE equipped with stereoscopy and head tracking. ECG and respiration were recorded as well as the participant's behavior and comments. Afterward, a semi-structured interview was carried out.In general, the subjective and physiological data from the experiment indicated that the VR version of the TSST induced a stress response in the seven participants. In particular, the peak increase in heart rate was close to rates observed in studies using the traditional TSST with real actors. These results suggest that virtual humans visualized with an immersive VR system can be used to induce stress under laboratory conditions.
