abstract = {Background: Schizophrenia is associated with impairments in verbal episodic memory. Strategy for Semantic Association Memory (SESAME) training represents a promising cognitive remediation program to improve verbal episodic memory. Virtual reality (VR) may be a novel tool to increase the ecological validity and transfer of learned skills of traditional cognitive remediation programs. The present proof-of-concept study aimed to assess the feasibility, acceptability, and preliminary efficacy of a VR-based cognitive remediation module inspired by SESAME principles to improve the use of verbal episodic memory strategies in schizophrenia. Methods: Thirty individuals with schizophrenia/schizoaffective disorder completed this study. Participants were randomized to either a VR-based verbal episodic memory training condition inspired by SESAME principles (intervention group) or an active control condition (control group). In the training condition, a coach taught semantic encoding strategies (active rehearsal and semantic clustering) to help participants remember restaurant orders in VR. In the active control condition, participants completed visuospatial puzzles in VR. Attrition rate, participant experience ratings, and cybersickness questionnaires were used to assess feasibility and acceptability. Trial 1 of the Hopkins Verbal Learning Test – Revised was administered pre- and post-intervention to assess preliminary efficacy. Results: Feasibility was demonstrated by a low attrition rate (5.88 %), and acceptability was demonstrated by limited cybersickness and high levels of enjoyment. Although the increase in the number of semantic clusters used following the module did not reach conventional levels of statistical significance in the intervention group, it demonstrated a notable trend with a medium effect size (t = 1.48},

abstract = {The availability of virtual reality (VR) in numerous clinical contexts has been made possible by recent technological advancements. One application is using VR for cognitive interventions with individuals who have mental disorders. Predicting the emotional states of users could help to prevent their discouragement during VR interventions. We can monitor the emotional states of individuals using sensors like an external camera, as they engage in various tasks within VR environments. The emotional state of VR users can be measured through arousal and valence, as per the Circumplex model. We used the Remote Collaborative and Affective Interactions (RECOLA) database of emotional behaviours. We processed video frames from 18 RECOLA videos. Due to the headset in VR systems, we detected faces and cropped the images of faces to use the lower half of the face only. We labeled the images with arousal and valence values to reflect various emotions. Convolutional neural networks (CNNs), specifically MobileNet-v2 and ResNets-18, were then used to predict arousal and valence values. MobileNet-v2 outperforms ResNet-18 as well as others from the literature. We achieved a root mean squared error (RMSE), Pearson’s correlation coefficient (PCC), and Concordance correlation coefficient (CCC) of 0.1495, 0.6387, and 0.6081 for arousal, and 0.0996, 0.6453, and 0.6232 for valence. Our work acts as a proof-of-concept for predicting emotional states from arousal and valence values via visual data of users immersed in VR experiences. In the future, predicted emotions could be used to automatically adjust the VR environment for individuals engaged in cognitive interventions. © 2023, Interactive Media Institute.

abstract = {State Social Physique Anxiety (SPA), in contrast to Trait SPA, is triggered by specific situations that elicit SPA. To date, no research has used virtual reality (VR) to recreate a situation that may elicit State SPA. The purpose of this study is to validate a virtual environment (VE) that simulates an anxiogenic situation to induce State SPA in women with obesity and high SPA. The high SPA group consisted of 25 self-identified women living with obesity and high Trait SPA. The low SPA group consisted of 20 self-identified women with low SPA. All participants were immersed in a virtual swimming pool environment for 10 min using a virtual reality headset. After the immersion, State SPA and fear of being negatively judged felt during immersion were measured with self-report questionnaires. A questionnaire assessing unwanted negative side effects was administered before and after the immersion. Using an ANCOVA with Trait SPA as covariate, State SPA was found to be significantly higher in the high SPA group. Fear of being judged negatively was also significantly higher in the high SPA group. Unwanted negative side effects scores did not increase post-immersion in either group. This study documents the validity of a novel VE for inducing State SPA in women with obesity and high SPA. © 2023 by the authors.},

abstract = {The effectiveness of in virtuo exposure-based treatment of performance-only social anxiety disorder (SAD) has been demonstrated in several studies. However, few studies have validated virtual environments with participants suffering from generalized SAD. The goal of this study is to confirm the potential of a virtual environment in inducing anxiety in adults suffering from generalized SAD, compared to adults without SAD, when engaged in awkward social interactions. Differences between participants from two different countries were also explored. The sample consisted of 15 participants with SAD from Canada, 17 participants without SAD from Canada, 16 participants with SAD from Spain, and 21 participants without SAD from Spain. All participants were immersed in a control virtual environment and in an experimental virtual environment considered potentially anxiety-inducing for individuals with generalized SAD. As hypothesized, results showed that the experimental virtual environment induced a higher level of anxiety than the control environment among participants with SAD compared to those without SAD. The impact on anxiety of each socially threatening task performed during the experimental immersion was statistically significant. In terms of anxiety responses, no significant differences were found between participants from Canada and Spain. However, spatial presence and ecological validity were higher in Canadians than in Spaniards. Unwanted negative side effects induced by immersions in virtual reality were higher in the SAD group. This study highlights the importance for therapists to engage people with SAD in clinically relevant tasks while immersed in VR psychotherapeutic applications. © 2023 by the authors.},

abstract = {Face recognition strategies do not generalize across individuals. Many studies have reported robust cultural differences between West Europeans/North Americans and East Asians in eye movement strategies during face recognition. The social orientation hypothesis posits that individualistic vs. collectivistic (IND/COL) value systems, respectively defining West European/North American and East Asian societies, would be at the root of many cultural differences in visual perception. Whether social orientation is also responsible for such cultural contrast in face recognition remains to be clarified. To this aim, we conducted two experiments with West European/North American and Chinese observers. In Experiment 1, we probed the existence of a link between IND/COL social values and eye movements during face recognition, by using an IND/COL priming paradigm. In Experiment 2, we dissected the latter relationship in greater depth, by using two IND/COL questionnaires, including subdimensions to those concepts. In both studies, cultural differences in fixation patterns were revealed between West European/North American and East Asian observers. Priming IND/ COL values did not modulate eye movement visual sampling strategies, and only specific subdimensions of the IND/COL questionnaires were associated with distinct eye-movement patterns. Altogether, we show that the typical contrast between IND/COL cannot fully account for cultural differences in eye movement strategies for face recognition. Cultural differences in eye movements for faces might originate from mechanisms distinct from social orientation. © 2023 Gingras et al.

Some studies have found a modulation of one or all of these components by one or both of these factors, whereas others have failed to show such results. The objective of this study was to investigate the effects of emotion and ambiguity on the behavioral and electrophysiological responses to a morphed emotion recognition task. Thirty-seven healthy participants (19 men) completed an emotion recognition task where photographs of a male face expressing the six basic emotions morphed with another emotion (in a proportion ranging from 26% to 74%) were randomly presented while electroencephalography was recorded. After each face presentation, participants were asked to identify the facial emotion. We found an emotional effect on the P1, N1, and N170, with greater amplitudes for some emotional facial expressions than for others. However, we found no significant emotional ambiguity effect or interaction between emotion and ambiguity for any of these components. These findings suggest that computation of emotional facial expressions (regardless of their ambiguity) occurs from the early stages of brain processing. © 2022 American Psychological Association},

abstract = {Background: Previous meta-analyses have shown a significant relationship between working alliance and treatment outcome in general. Some studies have examined the relationship between working alliance and treatment outcome during telepsychotherapy, but to the best of our knowledge, no study has examined the mediating role of individual components of the working alliance. Objective: As part of a clinical trial of cognitive behavioral therapy (CBT) for generalized anxiety disorder (GAD) delivered by videoconference (VC), the aim of this study is to examine the mediating role of intolerance of uncertainty on the relationship between the components of the working alliance and treatment outcome. Methods: A sample of 46 adults with primary GAD received 15 sessions of CBT for GAD delivered over VC. Participants completed the measure of working alliance immediately after the fifth therapy session. The degree of change in intolerance of uncertainty (a key psychological process) was assessed from pre- to posttreatment. Treatment outcome was assessed via changes in GAD symptoms from pretreatment to the 6-month follow-up. Results: The results revealed that the therapeutic bond did not predict treatment outcome (r=-0.23; P=.12). However, agreement on therapeutic goals and tasks did predict treatment outcome (r=-0.42; P=.004 and r=-0.37; P=.01, respectively). In addition, the relationship between consensus on therapeutic tasks and treatment outcome was completely mediated by changes in intolerance of uncertainty (unstandardized β=-0.03; r2=0.12), whereas consensus relative to treatment goals had a direct impact on treatment outcome. Conclusions: These results provide a better understanding of the differential role of the components of the working alliance in telepsychotherapy as a facilitative factor for changes in key cognitive processes, leading to therapeutic change. © 2021 JMIR Publications Inc.

However, it is not always possible to train repeatedly in front of a real audience. The present study aimed to assess the relevance of using a virtual classroom in clinical practice with school-age children and adolescents who stutter. Methods: Ten children and adolescents who stutter (aged 9–17 years old) had to speak in three different situations: in front of a real audience, in front of a virtual class and in an empty virtual apartment using a head-mounted display. We aimed to assess whether the self-rated levels of anxiety while speaking in front of a virtual audience reflect the levels of anxiety reported while speaking in front of a live audience, and if the stuttering level while speaking to a virtual class reflects the stuttering level while speaking in real conditions. Results: Results show that the real audience creates higher anticipatory anxiety than the virtual class. However, both the self-reported anxiety levels and the stuttering severity ratings when talking in front of a virtual class did not differ from those observed when talking to a real audience, and were significantly higher than when talking in an empty virtual apartment. Conclusion: Our results support the feasibility and relevance of using a virtual classroom to expose school-age children and adolescents who stutter to a feared situation during cognitive behavioral therapy targeting the fear of public speaking. © 2021 Elsevier Inc.},

The second objective was to explore the contribution of the egocentric virtual reality (VR) perspective of eLoriCorps to understanding body image disturbances (BIDs). The sample consisted of 53 female and 13 male adults. Body size dissatisfaction, body size distortion, perceived body size, and ideal body size were assessed. Overall, outcomes showed good agreement between allocentric perspectives as measured via VR and the FRS. The egocentric VR perspective produced different results compared to both the allocentric VR perspective and the FRS. This difference revealed discriminant validity and suggested that eLoricorps’ egocentric VR perspective might assess something different from the traditional conception of body dissatisfaction, which an allocentric VR perspective generally assesses. Finally, the egocentric VR perspective in assessing BIDs deserves to be studied more extensively to explore the possibility of finding two types of body image distortion: (a) an egocentric perceptual body distortion, referring to internal body sensation affected by intra-individual changes, and (b) an allocentric perceptual body distortion, referring to external body benchmarks constructed by inter-individual comparison occurring in a given cultural context. © 2020 by the authors.

abstract = {Aim: The aim of this study was to examine the effect of a water-friendly Projector-Based Hybrid Virtual Reality (VR) dome environment combined with standard pharmacological treatment on pain in young children undergoing burn wound care in hydrotherapy. Methods: This study was a prospective, within-subject crossover trial of 38 children aged 6 months to 7 years old (mean age = 1.8 years old). Each hydrotherapy procedure was divided into two equivalent wound care segments (No hybrid VR during one segment vs. Hybrid VR during the other segment, treatment order was randomized). Pain was measured using the 0–10 FLACC (Face, Legs, Activity, Cry Consolability scale) and the 0–10 NRS-obs (Numerical Rating Scale-obs). Results: Projector-Based Hybrid VR significantly reduced procedural pain levels measured by the FLACC (p = 0.026) and significantly increased patients' comfort levels (p = 0.002). Patients' pain levels rated by the nurses using the NRS-obs were non-significant between both groups (p = 0.135). No side effects were reported. Conclusion: Projector-Based Hybrid VR helped in reducing the pain related to hydrotherapy procedures in young children with burn wound injuries. This is the first study using virtual reality distraction with young children, and our findings are especially important because a large percentage of pediatric burn patients are very young.
