A Comparative Study of Virtual Footwear Try-on Applications in Virtual and Augmented Reality

Virtual try-on technology (VTO) in virtual reality (VR) and augmented reality (AR) has been developed for years to create novel shopping experiences for users by allowing them to virtually wear fashion products. Compared to garments or facial accessories, fewer studies have focused on virtual footwear try-on, regardless of user study or technical development. Thus, it is necessary to examine the effectiveness of existing VTO applications on the user's affective responses. In this study, we compared the user experience of three different footwear try-on methods (real, VR, and AR) with both physiological and psychological measures. Subjects conducted a try-on experiment on different pairs of sneakers. Each subject's gaze trajectory was recorded using an eye tracker and analyzed to show his/her visual attention in each method. Afterward, the subjects completed questionnaires to assess the sense of presence, usability, and the user experience score for the try-on processes, and subsequently attended a think-aloud procedure to express their thoughts. The analysis results of the collected data showed that the user experience produced by the VR and AR try-on is not comparable to that of the real environment. The results also revealed factors that negatively affect the quality of the user's interaction with the processes. These findings may provide insights into further improvements in VTO technology.

Susceptibility to COVID-19 Scams: The Roles of Age, Individual Difference Measures, and Scam-Related Perceptions

As the COVID-19 pandemic was unfolding, a surge in scams was registered across the globe. While COVID-19 poses higher health risks for older adults, it is unknown whether older adults are also facing higher financial risks as a result of COVID-19 scams. Here, we examined age differences in vulnerability to COVID-19 scams and individual difference measures (such as impulsivity, ad skepticism, and past experiences with fraud) that might help explain them. A lifespan sample (M = 48.03, SD = 18.56) of sixty-eight younger (18–40 years, M = 25.67, SD = 5.93), 79 middle-aged (41–64 years, M = 49.86, SD = 7.20), and 63 older adults (65–84 years, M = 69.87, SD = 4.50) recruited through Prolific completed questions and questionnaires online. In a within-subjects design, each participant responded to five COVID-19 solicitations, psychological measures, and demographic questions. Age group comparisons revealed that older adults were marginally less likely to perceive COVID-19 solicitations as genuine than middle-aged adults were. In addition, older adults perceived significantly fewer benefits than both younger and middle-aged adults did and perceived marginally higher risks than younger adults did. Hence, older adults did not exhibit greater vulnerability to COVID-19 scams. Regardless of age, intentions to respond to COVID-19 solicitations were positively predicted by higher levels of educational attainment, being married, past fraud victimization, and higher levels of positive urgency. As expected, stronger genuineness and benefit perceptions positively predicted action intentions, whereas stronger risk perceptions negatively predicted action intentions As such, COVID-19 scam susceptibility appears to be the result of a impulse control issue that is not easily inhibited, not even by past experiences of scam victimization.

INDIRECT WITNESSES OF TERRORIST ACTS: PSYCHOLOGICAL CONSEQUENCES OF INTIMIDATION

The victimhood of indirect witnesses of terrorist acts, which includes both the audience of the media and the population as a whole, is a complex socio-psychological phenomenon. The reasons victimizations are changes in the system of internal regulation of behavior, namely contradictions between the basic beliefs of people and the real consequences of terrorist acts, which are subjectively perceived as an unexpected, uncertain threat to existence (both objective and subjective), the irreparability of what can happen. Among the indirect witnesses were singled three response styles: slightly negative assessment, partial justification of the perpetrators of a terrorist act, negative emotional assessment with expressed anxiety. The most significant consequences of the psychological impact of terrorist acts on the media audience and the general population should be considered: the contradiction between the basic ideas of people and the reality demonstrated by the media: the subjective and objective unexpectedness of a terrorist act; incorrigibility of the offense. Shown, that psychological countermeasures should be based on the information component aimed at preventing inappropriate reactions, especially in the first days after the terrorist act, development and demonstration of optimal algorithms of behavior, prevent recourse to unconscious or subconscious impulses that violate basic illusions existence. With the presence of drivers that trigger patterns of victim-induced behavior, the media can provoke in the general population a massive loss of social and personal identity, meaning of life, prospects, to form a complex of inferiority, to induce certain adverse behaviors. The most significant consequences of the psychological impact of terrorist acts on the audience of the media and the general population should be considered the contradiction between the basic ideas of people (activate the images of death, destruction, horror of nothingness, which subconsciously everyone has. These "forms of the unspoken" violate three basic illusions of existence: the illusion of one's own immortality, the illusion of justice, the illusion of the hidden meaning of life) and the reality published by the media, which is subjectively perceived as a threat to existence; subjective and objective unexpectedness of a terrorist act; incorrigibility of the committed. Psychological measures to combat victimization should be based on the dominance of the information component of counteraction aimed at preventing dangerous reactions, especially in the first hours after the commission of a terrorist act, the development and demonstration of optimal behavioral algorithms. Keywords: indirect witnesses, terrorist attack, psychological measures, induced behavior, optimal algorithms

Effect of Playing Venue on Hormonal Responses and Psychological State of Inter-University Volleyball Players

The home advantage is a powerful wonder that happens in the realm of amateur and professional games where most teams win more than 50% of matches. The present study compared the effects of playing venue on hormonal responses and psychological state of inter-university volleyball players at home and away ground. A total of 96 male players age, 18 to 24 years from eight different public and private universities were selected as the subject in this study. Matches were scheduled in such a manner so that each team would play one match on home ground and one on away ground. The results of this study showed that a 13% reduction in the testosterone level of players was seen on the opponent’s home ground before playing the match, whereas, 18% elevation in cortisol level of players was recorded on the opponent’s home ground before-match. Psychological measures indicated that players’ cognitive and somatic anxiety levels were increased on away ground (10% and 13%, respectively) whereas, their self-confidence level declined by 17% on an opponent’s home ground before the commencement of the match. The present study supports the notion that there are differences in pre-competition hormonal and psychological states that may play a key role in ‘the home advantage’ which could affect players’ behavior and match outcomes.

Wii or Kinect? A Pilot Study of the Exergame Effects on Older Adults’ Physical Fitness and Psychological Perception

Exergames are now often implemented among older adults for health purposes. This study aimed to investigate whether playing Kinect and Wii exergames has effects on older adults’ physical fitness and psychological perceptions towards exergames. A total of 23 older participants aged above 60 years were recruited and randomly assigned into two groups, in which they played either Kinect or Wii Bowling exergames for three sessions in one week. Physiological and psychological measures were collected including heart rate, blood pressure, shoulder flexibility, as well as perceived benefits and intentions for future use. Findings indicated that exergames are equivalent to light-intensity exercises, and hence pose no or minimal risk to older adults. Older adults had a positive attitude towards exergames and have a strong willingness to engage in exergaming on a regular basis. Although no significant platform difference was identified, observation and qualitative findings suggested that Wii might provide a more intense physical activity than Kinect, while Kinect might obtain a higher perception among older adults than Wii. The study has several practical implications for both health professionals and exergame designers targeting the ageing population.

Susceptibility to COVID-19 Scams: Does Age Matter?

The COVID-19 pandemic has lead to a worldwide surge in COVID-19 related mass marketing scams. While COVID-19 poses higher health risks for older adults, it is unknown whether older adults are also facing higher financial risks as a result of such scams. Thus, the present study examined age differences in vulnerability to COVID-19 scams and factors that might help explain them. In June 2020, 68 younger (18 – 40 years, M = 25.67, SD = 5.93), 79 middle-aged (41 – 64 years, M = 49.86, SD = 7.20), and 63 older adults (65 – 84 years, M = 69.87, SD = 4.50) were recruited through Prolific. Participants responded to five COVID-19 solicitations, psychological measures, and demographic questions. Across solicitations, older adults perceived COVID-19 solicitations to offer significantly fewer benefits than both younger and middle-aged adults did. However, age groups neither differed in their perception of the solicitations’ risks and genuineness nor in their willingness to act in response to COVID-19 solicitations. Overall, intentions to respond to COVID-19 solicitations were positively predicted by higher levels of educational attainment, a previous history of fraud victimization, and higher levels of positive urgency. As expected, stronger genuineness and benefit perceptions positively predicted action intentions, whereas stronger risk perceptions negatively predicted action intentions. Older adults did not exhibit greater vulnerability to COVID-19 solicitations: If anything, they were more skeptical of the benefits associated with these solicitations. Irrespective of age, risk, benefit, and genuineness perceptions were the key factors associated with intention to respond to solicitations.

Fear, Peer Pressure, or Encouragement: Identifying Levers for Nudging Towards Healthier Food Choices in Multi-Cultural Singapore

With roots beyond behavioural economics to psychology, nudges can be applied for influencing healthy behaviours such as food choice and portions to decrease obesity for better public health outcomes. However, the effectiveness of the type of nudges are contentious with conflicting literature. In this pilot study, we conducted a 23-day study surveying the food choices that included portion, locus of control, demographic data, and psychological measures of personality, perceived stress, narcissism, regulatory focus, food choice motive and dietary restraint, with the participants given four intervention conditions of 12 instant messaging sent every two days through WhatsApp. The messages were either factual (control), focused on consequences, through social comparison, or persuasive. Running over the COVID19 pandemic, 17 participants completed the full surveys showing significant effects between the experimental conditions with the psychological parameters except for diet confidence and extraversion and conscientiousness, as well as cognitive restraint. We found BMI and waistline measurements to be suitable measurements, with promising results from the fear and social comparison nudges for food-related behaviours and exercise. Our pilot findings have implications to the use of nudges upon which future studies investigating psychological factors can build on.

Is There a Neuropathic-Like Component to Endometriosis-Associated Pain? Results From a Large Cohort Questionnaire Study

Background: Pain is one of the primary symptoms of endometriosis, a chronic inflammatory condition characterised by the presence of endometrial tissue outside the uterus. Endometriosis-associated pain is commonly considered as nociceptive in nature, but its clinical presentation suggests that it might have neuropathic-like properties in a subgroup of patients.Methods: This is a cross sectional study using an online survey. The survey was distributed by patient support websites. The survey was composed of validated questionnaires assessing pain symptoms, psychological measures and questions about number of surgeries.Main Results: We had 1,417 responses which met the inclusion criteria. Using standard painDETECT cut-off scores, we found that pain was classified as neuropathic in 40% of patients and as mixed neuropathic/nociceptive in a further 35%. In line with observations in other neuropathic conditions, the neuropathic subgroup reported higher pain intensities, greater psychological distress and cognitive impairment. Neuropathic pain was also more likely in those with more surgeries to the abdomen and a longer history of pain. As revealed by a cluster analysis, those with a neuropathic pain component could further be divided into two subgroups based on their sensory profile.Conclusions: The data presented here indicate that endometriosis-associated pain includes a neuropathic-like component in a substantial proportion of women. Although further investigation is required, our finding challenges the current conceptualisation of endometriosis-associated pain as nociceptive and advocates for a new perspective on this type of pain, which is so debilitating to a large number of women.

Knowledge and Self-Protective Practices Against COVID-19 Among Healthcare Workers in Vietnam

Background: In middle-income countries such as Vietnam, where healthcare resources are already constrained, protecting healthcare workers (HCWs) is essential for ensuring the sustainability of COVID-19 response in Vietnam. This study was conducted to assess the knowledge and practices regarding the prevention of the COVID-19 among the HCWs in Vietnam to identify the ways of disseminating information to maximize the safety of these essential workers.Methods: An online cross-sectional study, using respondent-driven sampling, was conducted in Vietnam with 742 participants within 2 weeks. The validity of the questionnaire was examined by exploratory factor analysis. Descriptive statistics were used to identify the level of knowledge and practices among the HCWs to prevent the COVID-19. Inferential statistics and regression modeling were used to identify the associated factors with results.Results: Vietnamese HCWs had a high level of knowledge with more than 75% of the participants demonstrating awareness of all the modes of transmission aside from air. The mean knowledge score was 3.7 ± 0.8 (range 1–5). Nearly all the participants relied on the Ministry of Health (98.3%) and the internet (95.5%) for information regarding the COVID-19. The participants endorsed a moderately high level of self-protective practices with mean scores of 4.2 and 3.6 (band score 1–5) for the precautionary and psychological measures, respectively. Nurses were more likely to practice the precautionary measures than doctors and the HCWs at the central level were more likely to practice the psychological measures than those at the district level.Conclusion: Future education initiatives should consolidate the latest literature in an accessible format, focusing initially on the gaps of knowledge regarding aerosol transmission. These initiatives should primarily focus on the doctors, especially those in emergency and intensive care departments.
