Real and virtual classrooms can trigger the same levels of stuttering severity ratings and anxiety in school-age children and adolescents who stutter

PurposeMany school-age children and adolescents who stutter experience the fear of public speaking. Treatment implications include the need to address this problem. 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.MethodsTen 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.ResultsResults 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.ConclusionOur 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.     

Frequency of stuttering during challenging and supportive virtual reality job interviews

This paper seeks to demonstrate the possibility of manipulating the frequency of stuttering using virtual reality environments (VREs). If stuttering manifests itself in VREs similarly to the way it manifests itself in real world interactions, then VREs can provide a controlled, safe, and confidential method for treatment practice and generalization. Though many researchers and clinicians recognize the need for generalization activities in the treatment of stuttering, achieving generalization in a clinical setting poses challenges to client confidentiality, safety, and the efficient use of a professionals’ time. Virtual reality (VR) technology may allow professionals the opportunity to enhance and assess treatment generalization while protecting the safety and confidentiality of their clients. In this study, we developed a VR job interview environment which allowed experimental control over communication style and gender of interviewers. In this first trial, persons who stutter (PWS) experienced both challenging and supportive VR job interview conditions. The percentage of stuttered syllables was calculated for both interviews for each participant. Self-reported ratings of communication apprehension and confidence were also obtained, and were not significantly correlated with stuttering severity. Results indicated that interviewer communication style affected the amount of stuttering produced by participants, with more stuttering observed during challenging virtual interviews. Additionally, the amount of stuttering observed during the VR job interviews was significantly, positively correlated with the amount of stuttering observed during an interview with the investigator prior to VR exposure. Participants’ subjective reports of the VR experience indicate reactions similar to those they report experiencing in the real world. Possible implications for the use of VR in the assessment and treatment of stuttering are discussed.

Educational objectives: After reading this article, the reader will be able to—(1) list some of the challenges to treatment generalization; (2) describe how virtual reality technology can assist in alleviating some of these challenges; (3) describe how the frequency of stuttering varies across two different virtual environments.     

The effects of an interactive cognitive task (ICT) in suppressing fatigue symptoms in driving

BackgroundProlonged drive on inter-urban, monotonous roads has the potential of causing a decrease in the general level of arousal leading to a state of underload and fatigue. This study examines the effectiveness of an interactive cognitive task (ICT) in delaying fatigue symptoms induced by underload conditions. The ICT is an auditory-motor task which is based on the basic principles of a knowledge game known as “Trivia”.MethodTen participants took part in two experimental sessions of 140 min drive in a fixed-base simulator. In a within-subject counterbalanced design one session consisted of driving without ICT and the other included ICT operation. In the ICT session the game was activated after 60 min of driving.ResultsWhen activated, the ICT increased physiological indicators of arousal, increased subjective feelings of alertness, and improved driving performance. The physiological and driving performance measures revealed that the ICT activation had an immediate but localized influence on arousal. Post-drive questionnaires showed that in the ICT condition, the participants’ level of motivation increased and their feelings of sleepiness decreased.ConclusionsEngaging in cognitive tasks can counteract the effects of underload and increases driving safety as long as they are active. However, additional research is necessary to determine the effects of long term use.     

Old Fears Die Hard: Return of Public Speaking Fear in a Virtual Reality Procedure

Exposure-based therapy is an effective treatment for social anxiety, but some patients relapse. We used a novel virtual reality procedure to examine spontaneous recovery (i.e., a return of fear over time) and fear renewal (i.e., the return of fear after a context switch) in individuals with fear of public speaking. On Day 1, 32 participants received exposure training before a virtual audience. On Day 8, participants completed a spontaneous recovery phase, followed by a fear renewal test, in which they gave a presentation in front of a new (context switch) or the same audience (no context switch). After exposure, participants exhibited a lower heart rate, subjective distress, negative valence, and arousal. One week later, participants showed spontaneous recovery of heart rate, and the context switch group showed renewal of subjective distress, negative valence, and arousal. Future studies can use this procedure to test interventions aimed at improving long-term exposure effects in individuals with public speaking fear.     

Adolescents with and without a facial difference: The role of friendships and social acceptance in perceptions of appearance and emotional resilience

This study investigated the role of friendships and social acceptance in self-perceptions of appearance and depressive symptoms, comparing adolescents with and without a facial difference. Adolescents with a visible cleft (n = 196) were compared with adolescents with a non-visible cleft (n = 93), and with a comparison group (n = 1832). Boys with a visible difference reported significantly more positive perceptions of friendships and less depressive symptoms than the comparison group. These results were interpreted in the context of indicators of emotional resilience. The objective measure of facial difference did not explain levels of depressive symptoms, while subjective measures did. Subjective ratings of appearance mediated the association between social acceptance and depressive symptoms in all samples. Gender did not contribute in explaining the paths between friendships, appearance, and depressive symptoms. The associations between perceptions of social acceptance, appearance, and emotional distress, support the possible utility of strengthening social experiences in preventing and treating appearance-concerns.     

Clinical utility of self-disclosure for adults who stutter: Apologetic versus informative statements

PurposeThe purpose of the present study was to explore the clinical utility of self-disclosure, particularly, whether disclosing in an informative manner would result in more positive observer ratings of the speaker who stutters than either disclosing in an apologetic manner or choosing not to self-disclose at all.MethodObservers (N = 338) were randomly assigned to view one of six possible videos (i.e., adult male informative self-disclosure, adult male apologetic self-disclosure, adult male no self-disclosure, adult female informative self-disclosure, adult female apologetic self-disclosure, adult female no self-disclosure). Observers completed a survey assessing their perceptions of the speaker they viewed immediately after watching the video.ResultsResults suggest that self-disclosing in an informative manner leads to significantly more positive observer ratings than choosing not to self-disclose. In contrast, use of an apologetic statement, for the most part, does not yield significantly more positive ratings than choosing not to self-disclose.ConclusionClinicians should recommend their clients self-disclose in an informative manner to facilitate more positive observer perceptions.     

L’évolution des facteurs prédictifs de la détresse psychologique des étudiants en contexte de Covid-19 : un modèle d’équation structurelle exploratoire

IntroductionStudents are at risk for mental health issues due to the COVID-19 pandemic. The implementation of lockdowns as a means to curb the spread of the disease have had an impact on this population, as observed in many international studies. However, few studies have investigated the longitudinal impact of COVID-19 lockdowns on students’ mental health.ObjectiveWe explored the relation between individual characteristics of students, context of life, difficulties in emotion regulation and psychological distress over the first two lockdowns in France during the COVID-19 pandemic.Methodology160 university students (90% female, mean of 24 years old) responded to an online questionnaire at three times points: once during the first lockdown during the COVID-19 pandemic in march 2020, a second time after this lockdown and a third time during the second lockdown. Difficulties in emotion regulation, psychological distress, acute stress, academic concerns, financial resources, and exchanges with professors were measured.ResultsAn exploratory structural equations model was developed to investigate the factors related to psychological distress (χ² = 1459.18, df = 1064, CFI = 0.910, RMSEA = 0.049, SRMR = 0.068). During both lockdowns, psychological distress was explained by academic concerns and lack of emotional clarity and acceptance. An indirect and negative significant relation was identified between financial difficulties, lack of exchanges with professors during the first lockdown, emotion clarity and experienced psychological distress during the second lockdown. Repeated measures ANOVAs identified high levels of acute stress during both lockdowns and a diminution during the deconfinement indicating an impact of sanitary measures on student's mental health.ConclusionCoherently with the Bruchon-Sweiser translational model of stress, emotion regulation capacities seem to have a central and moderating role in the experience of the pandemic for students. They would benefit greatly from appropriate therapeutic interventions in this pandemic situation and in general.     

Perceiving red decreases motor performance over time: A pilot study

IntroductionColors may influence motor performance.ObjectiveThe present study aimed to compare the effects of perception of red and green environments on physical (performance and heart rate) and psychological (perceived effort, anxiety and enjoyment) parameters during cycling trials.MethodTen cyclists achieved two identical series of three randomized 7-minute trials on home trainers, during which they were continuously exposed to red, green, and gray environments. Covered distance and heart rate were recorded during each trial, after which participants answered items intended to assess perceived effort, anxiety, and enjoyment experienced during the trial.ResultsResults showed that covered distance (ps ≤ .02) and heart rate (ps ≤ .03) were lower in the red environment than in the gray and green environments. Enjoyment was higher in the green environment than in the red environment (p = .006). The colored environments did not influence perceived effort and anxiety (ps > .05).ConclusionThis study is the first to show that perceiving red is detrimental for motor performance over an extended period of time.     

Continuity of phenomenology and (in)consistency of content of meaningful autobiographical memories

Phenomenology is a critical component of autobiographical memory retrieval; it reflects both (a) memory-specific features and (b) stable individual differences. Few studies have tested phenomenology longitudinally. The present work examined the continuity of memory phenomenology in a sample of Italians adults (N = 105) over a 4-week period. Participants retrieved two ‘key’ personal memories, a Turning Point and an Early Childhood Memory, rated the phenomenology of each memory, and completed measures of personality, psychological distress and subjective well-being. Phenomenological ratings were moderately stable over time (median correlation >.40), regardless of memory content. Personality traits, psychological distress and well-being were associated with phenomenology cross-sectionally and with changes in phenomenology over time. These results suggest that how individuals re-experience their most important personal memories is relatively consistent over time and shaped by both trait and state aspects of psychological functioning.     

Advanced age brings a greater reliance on visual feedback to maintain balance during walking

We implemented a virtual reality system to quantify differences in the use of visual feedback to maintain balance during walking between healthy young (n = 12, mean age: 24 years) and healthy old (n = 11, 71 years) adults. Subjects walked on a treadmill while watching a speed-matched, virtual hallway with and without mediolateral visual perturbations. A motion capture system tracked center of mass (CoM) motion and foot kinematics. Spectral analysis, detrended fluctuation analysis, and local divergence exponents quantified old and young adults’ dynamic response to visual perturbations. Old and young adults walked normally with comparable CoM spectral characteristics, lateral step placement temporal persistence, and local divergence exponents. Perturbed visual flow induced significantly larger changes in mediolateral CoM motion in old vs. young adults. Moreover, visual perturbations disrupted the control of lateral step placement and compromised local dynamic stability more significantly in old than young adults. Advanced age induces a greater reliance on visual feedback to maintain balance during waking, an effect that may compensate for degradations in somatosensation. Our findings are relevant to the early diagnosis of sensory-induced balance impairments and also point to the potential use of virtual reality to evaluate sensory rehabilitation and balance training programs for old adults.     

Effects of gait speed on the body’s center of mass motion relative to the center of pressure during over-ground walking

Preferred walking speed (PWS) reflects the integrated performance of the relevant physiological sub-systems, including energy expenditure. It remains unclear whether the PWS during over-ground walking is chosen to optimize one’s balance control because studies on the effects of speed on the body’s balance control have been limited. The current study aimed to bridge the gap by quantifying the effects of the walking speed on the body’s center of mass (COM) motion relative to the center of pressure (COP) in terms of the changes and directness of the COM-COP inclination angle (IA) and its rate of change (RCIA). Data of the COM and COP were measured from fifteen young healthy males at three walking speeds including PWS using a motion capture system. The values of IAs and RCIAs at key gait events and their average values over gait phases were compared between speeds using one-way repeated measures ANOVA. With increasing walking speed, most of the IA and RCIA related variables were significantly increased (p < 0.05) but not for those of the frontal IA. Significant quadratic trends (p < 0.05) with highest directness at PWS were found in IA during single-limb support, and in RCIA during single-limb and double-limb support. The results suggest that walking at PWS corresponded to the COM-COP control maximizing the directness of the RCIAs over the gait cycle, a compromise between the effects of walking speed and the speed of weight transfer. The data of IA and RCIA at PWS may be used in future assessment of balance control ability in people with different levels of balance impairments.     

Psychometric properties of a French version of the Implicit Theories of Emotion Scale

IntroductionInspired by Carol Dweck's work on naive theories of intelligence, the implicit theory of emotions refers to beliefs regarding the general functioning of emotions, specifically, their controllability. Some individuals view emotions as uncontrollable (entity theory), while others think that emotions can be modulated (incremental theory). These beliefs guide the emotional regulation strategies that individuals use and influence subjective well-being.ObjectiveThe present study explores the psychometric properties of the French version of the Implicit Theories of Emotion Scale developed by Tamir et al. (2007).MethodOne hundred seventy-seven participants aged 18 to 72 years old (M = 34 years old) completed the Implicit Theories of Emotion Scale in conjunction with two other questionnaires: subjective well-being and emotional regulation strategies.ResultsFactor analyses identified a one-dimensional structure; the internal reliability (alpha = .81) and test-retest reliability indices (r = .69) were satisfactory. The study replicated the main results of contemporary international studies concerning the mediating role of cognitive reappraisal and further documents the pivotal role of positive reappraisal in the association between implicit theories and well-being.ConclusionThe discussion highlights clinical and theoretical interests and the usefulness of the Implicit Theories of Emotion Scale.     

Analyse de la structure factorielle du questionnaire de tempérament EAS (version parents) auprès de deux échantillons d’enfants âgés de deux à cinq ans et de six à neuf ans

IntroductionThe EAS temperament survey (Buss & Plomin, 1984) allows the measurement of four heritable and relatively stable dimensions of temperament, that is, Activity, Emotionality, Sociability and Shyness.ObjectiveA French translation of this tool has been validated with children aged from 6 to 12 years (Gasman et al., 2002), our goal is to extend the validation process to a group of younger children.MethodThe temperament of 350 children aged from 2 to 5 years and of 290 children aged from 6 and 9 years was assessed by the EAS and DOTS-R questionnaires (parental ratings).ResultsMulti-group confirmatory factor analysis allowed to confirm the measurement invariance and the structural invariance of the EAS (four-factor model) on both samples and showed that the scale scores are good approximations of the factor scores. Furthermore, there were no significant sex differences in temperament scores and we found that older children were on average less active and more emotional compared to younger ones. Finally, internal consistency and convergent validity of each scale were fairly satisfying.ConclusionThe EAS (parental ratings) can thus be used from the age of 2 years, facilitating the study of temperament development during childhood.     

Acute effects of alcohol on memory: Impact of emotional context and serial position

Although the amnestic effects of alcohol in humans are well known, its effects on emotional memory are unclear. In this study, using a randomized double-blind placebo-controlled design, we examine narrative emotional episodic memory in healthy human female volunteers (n = 32) who received either a single dose of alcohol (0.6 g/kg), or a placebo and then viewed neutral story elements presented in either a neutral or emotional context. Memory was tested for gist and detail of the neutral elements 3 days later in a surprise recognition test. Since alcohol modulates GABAergic neurotransmission and may exert its effects on emotion through the limbic system, we predicted that acute alcohol treatment would reduce the expected emotional memory-advantage for gist, leaving detail memory relatively unaffected. Furthermore, given previous findings showing that ‘primacy’ memory is enhanced by physiological arousal, we predicted that reduced arousal produced by alcohol would have the opposite effect and impair primacy memory relative to the middle or ‘recency’ sections of the narrative. Emotional arousal was expected to oppose this effect, so impaired primacy memory following alcohol was only expected in the neutral version of the narrative. Although there was a main effect of story phase (though not of story version), contrary to expectations, alcohol impaired primacy memory for emotionally encoded neutral material. The results suggest that under certain circumstances emotional context or physiological arousal make memories labile and susceptible to disruption through pharmacological manipulation during encoding.     

Beauty is in the sex of the beholder: An examination of the effects of interviewer characteristics on assessments of respondent attractiveness

Research exploring the effects of physical attractiveness frequently assesses attractiveness by employing subjective appraisals by independent raters. However, there is reason to believe that rater characteristics – especially their sex – may systematically bias subjective ratings of physical attractiveness. The current study explores this possibility by analyzing data from the National Longitudinal Study of Adolescent Health (N = 13,330). Analyses of these data revealed that ratings of physical attractiveness are significantly influenced by the sex of the interviewer/rater. Specifically, male raters were significantly less likely than female raters to assess males as attractive, very attractive, and very unattractive. The results are explained within the context of evolutionary psychology and illustrate a methodological concern for research on physical attractiveness.     

Validation française d’une version brève de l’Échelle de satisfaction maritale

IntroductionFew measuring instruments of couple satisfaction maximizing the individual perception of the relationship exists in French. Settings such as Liaison psychiatry of a general hospital could benefit from a questionnaire adapting to a variety of clinical profiles.ObjectiveThis article proposes a French revision and validation of the Marital Satisfaction Scale (MSS; Roach, Frazier, and Bowden, 1981), a 48-item self-reported questionnaire designed to evaluate personal satisfaction towards one's couple relationship.MethodA sample of 349 community-dwelling individuals aged 20–85 answered the MSS, the Dyadic Adjustment Scale (DAS; Spanier, 1976), and a series of inquiries related to sociodemographics. As an initial Exploratory Factor Analysis (EFA) did not validate the unidimensional structure postulated by the original authors, the item number was reduced to 14.ResultsThis brief version of the scale (MSS-14) was subsequently validated with an internal replication analysis, a strong criterion-related validity with the DAS (r_s = 0.73, P < 0.001), an excellent internal consistency (α = 0.961, IC à 95% [0.955, 0.967]), a strong test-retest reliability (r_s = 0.90, CI à 95% [0.85, 0.93], P < 0.001, Z = − 0.033, P = 0.973), and strong item-to-total correlations (> 0.69). The MSS-14 could differentiate individuals with and without marital distress (AUC = 0.97), while no sociodemographic variable seemed to have a significant influence on couple satisfaction.ConclusionThe MSS-14 appears to be a reliable instrument to assess the personal satisfaction towards a couple relationship in community-dwelling adults.     

Under what conditions do lay people and health professionals accept a breach of doctor-patient confidentiality regarding a patient with signs of terrorist radicalization?

IntroductionConfidentiality is crucial to the establishment of a strong patient-physician relationship. However, certain situations create a dilemma for the physician who is faced with the choice of either respecting medical confidentiality or protecting others from a serious risk of violence.ObjectiveThis study aimed to observe how lay people and health professionals assessed the acceptability of breaching confidentiality when a physician is confronted to a patient showing signs of terrorist radicalization.MethodA total of 228 participants (174 from the general population and 54 health professionals) judged the acceptability of 54 scenarios which were constructed through the orthogonal combination of 4 factors frequently mentioned in the literature: presence of a “Psychiatric disorder”; “Signs of radicalization”; “Projects of violence”; “Collegiality”. Variance and cluster analyses were performed on all the raw data.ResultsResults showed that all factors influenced the judgment of participants but that “Psychiatric disorders” had a weaker impact. Five clusters were identified: “Favorable if collegiality” (n = 23); “Favorable to breach confidentiality” (n = 77); “Unfavorable to breach confidentiality” (n = 26); “Sensitive to all factors” (n = 71); “Favorable if violence” (n = 31), respectively with mean ratings of 5.87, 8.42, 3.64, 6.30 and 7.16, on an acceptability scale of 0–10.ConclusionThe importance that the great majority of participants attribute to these factors indicates that they influence their judgments in this specific context.     

Are conservatives happier than liberals? Not always and not everywhere

Prior research has shown that conservatives report higher levels of subjective well-being than liberals (happiness gap). We investigate to what extent this phenomenon exists in different time periods within the United States (Study 1, N = 40,000) and in different countries (Study 2, N = 230,000). Consistent with our hypotheses grounded in the “shared reality” and person-culture fit literature, conservatives were happier and more satisfied with their lives than liberals to the extent that the conservative political ideology prevailed in their socio-cultural context, be it a specific time period in the U.S. or a specific country. These results show that the happiness gap between conservatives and liberals is less universal than previously assumed.     

Partial body weight support treadmill training speed influences paretic and non-paretic leg muscle activation,stride characteristics,and ratings of perceived exertion during acute stroke rehabilitation

BackgroundIntensive task-specific training is promoted as one approach for facilitating neural plastic brain changes and associated motor behavior gains following neurologic injury. Partial body weight support treadmill training (PBWSTT), is one task-specific approach frequently used to improve walking during the acute period of stroke recovery (<1 month post infarct). However, only limited data have been published regarding the relationship between training parameters and physiologic demands during this early recovery phase.ObjectiveTo examine the impact of four walking speeds on stride characteristics, lower extremity muscle demands (both paretic and non-paretic), Borg ratings of perceived exertion (RPE), and blood pressure.DesignA prospective, repeated measures design was used.MethodsTen inpatients post unilateral stroke participated. Following three familiarization sessions, participants engaged in PBWSTT at four predetermined speeds (0.5, 1.0, 1.5 and 2.0 mph) while bilateral electromyographic and stride characteristic data were recorded. RPE was evaluated immediately following each trial.ResultsStride length, cadence, and paretic single limb support increased with faster walking speeds (p ⩽ 0.001), while non-paretic single limb support remained nearly constant. Faster walking resulted in greater peak and mean muscle activation in the paretic medial hamstrings, vastus lateralis and medial gastrocnemius, and non-paretic medial gastrocnemius (p ⩽ 0.001). RPE also was greatest at the fastest compared to two slowest speeds (p < 0.05).ConclusionsDuring the acute phase of stroke recovery, PBWSTT at the fastest speed (2.0 mph) promoted practice of a more optimal gait pattern with greater intensity of effort as evidenced by the longer stride length, increased between-limb symmetry, greater muscle activation, and higher RPE compared to training at the slowest speeds.
