abstract = {Purpose Speaking in class is challenging for students who stutter. Cognitive-behavioral therapy (CBT) with exposure in virtual reality (VR) emerges as a promising intervention for treating speaking anxiety in pediatric populations. This pilot study tested if real-time avatar-based VR can elicit anxiety responses while remaining acceptable to youth who stutter. Method Twelve students who stutter (aged 9–18) were randomly assigned to a single training session conducted either (1) in VR with a realistic avatar controlled live by their SLP, or (2) in role-play with their SLP, before facing a real actor. We assessed system acceptability, anxiety levels and perceived self-efficacy. Results The VR system was well accepted and elicited physiological arousal comparable to real-life interactions. Although participants reported experiencing less anxiety during VR, skin conductance level showed higher arousal; suggesting a divergence between the subjective report and physiological response. Finally, one training session (either in VR or with the SLP) did not produce gains in self-efficacy or decrease in anxiety related to the final real-actor conversation. Conclusion This study demonstrates evidence that the potential use of immersive VR could represent an acceptable and viable complementary strategy for SLP treatment, that could control exposure parameters while evoking physiological responses similar to real-life contexts. The differences between subjective and physiological measures suggest that VR is inducing anxiety responses differently than it was perceived. Further research could investigate the use of VR as anxiety interventions for students who stutter and should be explored across multi-session studies to understand their therapeutic effect. © 2026 The Authors.},

abstract = {Patients living in complex care (CC) frequently experience pain. The study goals were to assess the feasibility of using virtual reality (VR), and the potential for VR to impact pain, mood, and quality of life in two groups of patients living in CC, those experiencing acute pain during wound dressing changes and those experiencing chronic pain. Participants were offered 30 minutes of immersive, passive VR experiences using a Meta Quest 2 headset, 3 times/week for 3 weeks. Pain and mood were assessed pre, during and post each VR session. Pain, mood and quality of life were assessed before and after the 3-week intervention. Feasibility was assessed after each session. Three women (average age 66.3) with wound dressing changes completed an average of 3.7 sessions (25.5 minutes/session). Two-thirds experienced meaningful declines in pain with VR. Seventeen participants (6 men, 11 women, average age 58.4) with chronic pain completed an average of 3.1 sessions (21.4 minutes/session). Pain was significantly decreased from pre to post VR and pre to during VR. Mood and quality of life did not change. Both groups had low levels of discomfort and nausea, and high levels of satisfaction and immersiveness. Most participants enjoyed the experience and appreciated the immersion. It was challenging to adapt the headset to patients in non-seated positions who could not use VR controllers. VR is a promising modality to manage pain in patients living in CC. More work needs to be done to confirm the results and implement VR in clinical settings. © 2025, Interactive Media Institute. All rights reserved.},

abstract = {Background/Objectives: The aim was to identify patterns of autonomic and neuroendocrine reactivity to an immersive virtual reality (VR) social-emotional stressor and explore their associations with perceived stress and eating behavior. Methods: This one-group pretest–posttest study included 30 children and adolescents with obesity (15 boys and 15 girls), aged 8 to 17 years. The VR protocol consisted of two consecutive phases: a 5 min relaxation phase using the Forest application and a 5 min stimulation phase using a cognitively engaging VR game designed to elicit social-emotional stress. Physiological responses were measured using heart rate variability (HRV) indices and salivary stress biomarkers, including cortisol and alpha amylase. Subjective stress and eating responses were assessed via visual analogue scales (VAS) administered immediately post-exposure. The Three-Factor Eating Questionnaire (TFEQ-R21C) was used to evaluate cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). Results: The cortisol reactivity was blunted and may reflect both the attenuated HPA axis responsiveness characteristic of pediatric obesity and the moderate psychological challenge of the VR stressor used in this study. Two distinct autonomic response patterns were identified via exploratory factor analysis: (1) parasympathetic reactivity, associated with increased RMSSD and SDNN and decreased LF/HF, and (2) sympathetic activation, associated with increased heart rate and alpha-amylase levels and reduced RR intervals. Parasympathetic reactivity was correlated with lower perceived stress and anxiety, but also paradoxically with higher uncontrolled eating (UE). In contrast, sympathetic activation was associated with greater cognitive restraint (CR) and higher anxiety ratings. Conclusions: This study demonstrates that immersive VR game exposure elicits measurable autonomic and subjective stress responses in children and adolescents with obesity, and that individual differences in physiological reactivity are relevantly associated with eating behavior traits. The findings suggest that parasympathetic and sympathetic profiles may represent distinct behavioral patterns with implications for targeted intervention. © 2025 by the authors.},

abstract = {This study used data from a randomized control trial on cognitive behavior therapy for social phobia testing the effectiveness of exposure conducted in virtual reality. Measures of cognitive mechanisms had been collected but never analyzed. The study was motivated by a recent publication mentioning that potential aversive outcomes of being judged in virtual reality and by virtual characters have no objective negative consequence in daily life. A sample of 51 adults completed outcome and cognitive mechanism measures at a pretreatment, after 14 weeks of treatment or being on a waiting list, and at a 6-month follow-up. Results demonstrate that conducting exposure in virtual reality led to reductions in dysfunctional beliefs about the perceived consequences of feared social threats, about the likelihood of these feared threats occurring, as well as an increase in perceived self-efficacy to face social situations. These changes were statistically significant when compared to the waiting list condition, remained stable at the 6-month follow-up, and were no less important than when exposure was conducted in vivo. All predictors significantly correlated (p < .001) with the two measures of treatment outcome. Further analyses of cognitive mechanism measures predicting treatment outcomes revealed that, when controlling for shared variance, changes in perceived likelihood and in self-efficacy contributed significantly to patients’ improvement, whereas the role of perceived consequences was only a predictor of self-efficacy. © 2025, Interactive Media Institute.

abstract = {Background: Cognitive remediation improves cognition and psychosocial functioning in individuals with psychotic disorders. The use of virtual reality (VR) to deliver cognitive remediation in immersive environments that mimic real cognitively challenging situations has the potential to increase engagement to treatment and further enhance its impact on functioning. Objective: We aimed to codevelop a cognitive remediation program in VR with individuals with psychotic disorders and health care professionals to identify and address their needs. Methods: Individuals with lived experience of a psychosis-spectrum condition (n=11) met 9 times and the health care professionals (n=7) met 3 times. Participants discussed personal and professional opinions on the challenges associated with cognitive difficulties in individuals with psychotic disorders. They also provided feedback on the program development. Results: We discerned 4 themes from the content expert working groups: the need for a program to address cognitive impairments, the key program design elements to support cognitive rehabilitation, the importance of leveraging technology as an intervention tool, and the need to improve community functioning. In total, 3 themes were identified for the health care professionals: the need for a clinically relevant program that addresses the research-to-practice gap, the need to improve patient engagement in services, and the need for a program that addresses the limited resources in health care. The needs of our end-user experts were placed at the center of the program development process. When possible, we also integrated their suggestions, like the incorporation of a virtual coach within the immersive environment. Conclusions: Individuals with lived experience and health care professionals have distinct needs, which have informed the co-design of a novel cognitive remediation program in VR, ThinkTactic VR. To our knowledge, ThinkTactic VR is one of the first co-designed and codeveloped cognitive remediation programs in VR using an iterative, user-centered approach involving both individuals with psychotic disorders and health care professionals. ©Jasmin Yee, Hannah Matheson, Bryce J M Bogie, Émilie Du Perron, Alexandra Thérond, Maëlle Charest, Catheleine van Driel, Marika Goyette, Ya Ting Lei, Chelsea Noël, Kagusthan Ariaratnam, Greg Collins, Chris Gorman, Ana-Maria Cretu, Simon Tremblay, Marie-Christine Rivard, Catherine Cullwick, Crystal Morris, David G Attwood, Alexandra Baines, Angela Stewart, Stéphane Bouchard, Christopher R Bowie, Synthia Guimond.},

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 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.

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.},
