Effects of Virtual Human Appearance Fidelity on Emotion Contagion in Affective Inter-Personal Simulations
IEEE Transactions on Visualization and Computer Graphics, 2016Co-Authors: Matias Volante, Nathan Newsome, Himanshu Chaturvedi, Tania Roy, Sabarish V. Babu, Elham Ebrahimi, Shaundra B. Daily, Tracy FasolinoAbstract:Realistic versus stylized depictions of virtual humans in simulated inter-personal situations and their ability to elicit emo- tional responses in users has been an open question for artists and researchers alike. We empirically evaluated the effects of near visually realistic vs. non-realistic stylized appearance of virtual humans on the emotional response of participants in a medical virtual reality system that was designed to educate users in recognizing the signs and symptoms of patient deterioration. In a between- subjects experiment protocol, participants interacted with one of three different appearances of a virtual patient, namely visually realistic, cartoon-shaded and charcoal-sketch like conditions in a mixed reality simulation. Emotional impact were measured via a combination of quantitative objective measures were gathered using skin Electrodermal Activity (EDA) sensors, and quantitative subjective measures such as the Differential Emotion Survey (DES IV), Positive and Negative Affect Schedule (PANAS), and Social Presence questionnaire. The emotional states of the participants were analyzed across four distinct time steps during which the medical condition of the virtual patient deteriorated (an emotionally stressful interaction), and were contrasted to a baseline affective state. Objective EDA results showed that in all three conditions, male participants exhibited greater levels of arousal as compared to female participants. We found that negative affect levels were significantly lower in the visually realistic condition, as compared to the stylized appearance conditions. Furthermore, in emotional dimensions of interest-excitement, surprise, anger, fear and guilt participants in all conditions responded similarly. However, in Social emotional constructs of shyness, presence, perceived personal- ity, and enjoyment-joy, we found that participants responded differently in the visually realistic condition as compared to the cartoon and sketch conditions. Our study suggests that virtual human appearance can affect not only critical emotional reactions in affective inter-personal training scenarios, but also users’ perceptions of personality and Social Characteristic of the virtual interlocutors.

population heterogeneity and state dependence state of the evidence and directions for future research
Journal of Quantitative Criminology, 2000Co-Authors: Daniel S Nagin, Raymond PaternosterAbstract:Criminological research has consistently uncovered a positive correlationbetween past and current criminal behavior. Continuity in offending overtime can be attributed to at least two processes—populationheterogeneity and state dependence. A population heterogeneity processattributes stability in offending over time to differences in ananti-Social Characteristic (self-control, impulsivity, psychopathicpersonality) across persons that is established early in life andtime-stable thereafter. An implication of a population heterogeneityexplanation for continuity in offending over time is that the anti-SocialCharacteristic is likely to have reverberations throughout life, takingmany manifestations later in life (unemployment, drug addiction, maritalinstability). Any observed correlation between these later life events andcriminality, therefore, is spurious rather than causal, due to the factthat they are all the effects of a common cause. A state dependenceexplanation, in contrast, attributes observed stability in criminaloffending to a process of contagion. That is, criminal behavior has agenuine causal effect on subsequent criminality by eroding constraintsand strengthening incentives to crime. The implication of a statedependence process is that criminal conduct may be influenced by laterlife events. In this paper, we draw a connection between populationheterogeneity and state dependence processes and extant criminologicaltheory. We also review the literature that has investigated theplausibility of these two processes. Finally, concluding that weknow very little about them we make recommendations for future researchon population heterogeneity and state dependence.

the medico Social Characteristic of persons with multiple injuries
Problemy sot︠s︡ialʹnoĭ gigieny zdravookhranenii︠a︡ i istorii medit︠s︡iny NII sot︠s︡ialʹnoĭ gigieny ėkonomiki i upravlenii︠a︡ zdravookhraneniem im. , 2010Co-Authors: U I ZaĭtsevaAbstract:The analysis of a medico-Social Characteristic of victims with multiple injuries in Omsk revealed the nature of multiple and associated injuries distribution among Socially-adapted and Socially-disadapted groups of population. The top place was taken by multiple injuries received as a result of road accidents. The sections of population most open to multiple injuries were determined. The age peculiarity of such injuries, the accompanying diseases influencing the nature of injury received and the future prognosis in victims were identified.
