Videoconference to supervise early intensive behavioral intervention: A preliminary evaluation of acceptability

At present, early intensive behavioral intervention (EIBI) for children with autism spectrum disorders is the intervention that has the strongest empirical support. EIBI requires frequent supervision by qualified professionals. Norway, like many other countries, has a shortage of qualified supervisors, particularly in rural regions. This study used a reversal design to investigate how supervisors and supervisees perceive the quality of EIBI supervision and the local team's preparedness when supervision was provided either on-site or via videoconference. Calculations were made on how much time could be saved on travel when part of the supervision was provided via videoconference. There were no significant differences in the supervisors' and supervisees' ratings of on-site and videoconference supervision. Moreover, the supervisors found the local EIBI teams to be better prepared when supervision was provided via videoconference, and the videoconference supervision meetings were shorter. The study discusses the implications of these findings for the accessibility of EIBI and case capacity and proposes some areas for further research.     

Caregiver-implemented toilet training procedures for children with autism spectrum disorder

Children with Autism Spectrum Disorder often exhibit deficits in daily living skills, including toileting skills. Previous studies have evaluated components of common toilet training practices, including differential reinforcement, sit schedules, fluid loading, underwear, and wet alarms. The purpose of this study was to replicate and extend previous work by delivering all coaching remotely. Three caregiver-child dyads participated in this study. A researcher coached caregivers on the implementation of the protocol using a modified behavioral skills training approach via telehealth. Caregivers submitted daily toileting data and weekly audio recordings for treatment integrity checks. The sit schedule fading was individualized to meet the needs and preferences of each family. All caregivers implemented the protocol with high integrity. Two participants met the mastery criteria at the 90-min sit schedule and maintained performance at the 1- and 6-week maintenance follow up probes. The third participant, despite an interruption of treatment, also reached mastery.     

Living (dys)regulated and alienated young masculinity—Young men's embodied experiences of mental disorders and suicidality

Introduction

Mental disorders, such as depression and anxiety with interlinked suicidality, are the leading cause of health-related disability among young men. Knowledge of the interaction between emotional, bodily, social and gendered mental health processes in young men is limited and therefore needed.

Aim

This study aimed to explore young men's lived embodied experiences of mental disorders and suicidality, and to conceptualise these by integrating affective–emotional, physiological, social and gendered processes.

Methods

Semistructured individual interviews were conducted with 13 young men who had sought professional help for mental disorders and suicidality. Grounded theory (GT) was used with a social constructivist perspective.

Results

The results comprise one core category—Living (dys)regulated and alienated young masculinity—with related categories “battling with the emotional body,” “suffering in social silence” and “balancing embodied darkness and distress.” The GT illustrates how young men navigate and manage their embodied and emotional suffering in a context of “regulative” masculine and social norms alongside insufficient social support.

Conclusion

Our results suggest that young men's lived embodied experiences of mental disorders and suicidality can be understood as a dynamic process of internal and external “(dys)regulation and alienation.” The generated GT provides a broad tentative explanation model, contributing to theory development, and serves as a basis for gender-sensitive interventions—in both psychotherapy and physiotherapy—integrating body, mind and the social context.     

Examining stimuli paired with alternative reinforcement to mitigate resurgence in children diagnosed with autism spectrum disorder and pigeons

In two laboratory experiments, we examined whether stimuli paired with alternative reinforcers could mitigate resurgence of a previously reinforced target response with pigeons (Experiment 1) and children diagnosed with Autism Spectrum Disorder (Experiment 2). In Phase 1, we arranged food reinforcement according to a variable-ratio schedule for engaging in a target response. In Phase 2, we arranged extinction for target responding and differentially reinforced alternative responding according to a fixed-ratio schedule, with every alternative-reinforcer delivery paired with a change in keylight color (Experiment 1) or automated verbal (praise) statement (Experiment 2). In Phase 3, we assessed resurgence during extinction of target and alternative responding in the presence versus absence of continued presentation of the paired stimulus. Despite variation across sessions, resurgence on average was lower when continuing to present the paired stimuli in all pigeons and children while maintenance of alternative responding did not differ between assessments. These findings indicate that stimuli paired with alternative reinforcement can modestly decrease resurgence, but further examination of their efficacy and a better understanding of the underlying processes are necessary before they can be recommended for clinical use in reducing resurgence of clinically relevant problem behavior.     

Linking dynamical perceptual decisions at different levels of description in motion pattern formation: computational simulations

A two-level dynamical model of motion pattern formation is developed in which local motion/ nonmotion perceptual decisions are based on inhibitory competition between area V1 detectors responsive to motion-specifying versus motion-independent stimulus information, and pattern-level perceptual decisions are based on inhibitory competition between area MT motion detectors with orthogonal directional selectivity. The model accounts for the effects of luminance perturbations on the relative size of the pattern-level hysteresis effects reported by Hock and Ploeger (2006) and also accounts for related experimental results reported by Hock, Kelso, and Sch?ner (1993). Single-trial simulations demonstrated the crucial role of local motion/nonmotion bistability and activation-dependent future-shaping interactions in stabilizing perceived global motion patterns. Such interactions maintain currently perceived motion patterns by inhibiting the soon-to-be-stimulated motion detectors that otherwise would be the basis for the perception of an alternative pattern.     

Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.

Validity and reliability of self-assessed physical fitness using visual analogue scales

To test the validity and reliability of self-assessed physical fitness samples included healthcare assistants working at a hospital (women=170, men=17), persons working with physically and mentally handicapped patients (women=530, men= 123), and two separate groups of healthcare students (a) women=91 and men=5 and (b) women=159 and men=10. Five components of physical fitness were self-assessed by Visual Analogue Scales with illustrations and verbal anchors for the extremes: aerobic fitness, muscle strength, endurance, flexibility, and balance. Convergent and divergent validity were evaluated by age-adjusted correlations stratified by sex with performance-based measures of physical fitness. Self-assessed aerobic fitness (r = .36 - .64) (women/men), muscle strength (r = .30 - .51), and flexibility (r = .36 - .31) showed moderate convergent validity. The divergent validity was satisfactory except for flexibility among men. The reliability was moderate to good (ICC = .62 - .80). Self-assessed aerobic fitness, muscle strength, and flexibility showed moderate construct validity and moderate to good reliability using visual analogues.     

Children's prepared and unprepared lies: can adults see through their strategies?

We investigated adults' ability to detect children's prepared and unprepared lies and truths. Furthermore, we examined children's strategies when lying. Thirty children (11–13 years) were interviewed about one self‐experienced and one invented event each. Half had prepared their statements, the other half not. Sixty adult observers assessed the veracity of 10 videotaped statements each. Overall deception detection accuracy (51.5%) was not better than chance. The adults showed higher accuracy for unprepared statements (56.6%), than prepared statements (46.1%). The adults reported to have used more verbal than nonverbal cues to deception, especially the Detail criterion. The most frequent verbal strategy reported by the children was to use real‐life components (e.g. own or others' experiences); the most frequent nonverbal strategy was to stay calm. Arguably, the low accuracy is due to adults' failure to see through the lying children's strategies. Copyright © 2006 John Wiley & Sons, Ltd.     

Applying a Modified Moral Decision Making Model to Change Habitual Car Use: How Can Commitment be Effective?

Une intervention basée sur une théorie a été réalisée auprès d’un échantillon de 297 automobilistes pour tenter de lancer de nouvelles habitudes de déplacement (essayer de préférer les transports en commun plutôt que la voiture). Un modèle de modification d’une décision morale relevant de la théorie de Schwartz et Howard (1981) fut exploité dans la conception d’une intervention associant une technique de décristallisation des comportements antérieurs (remise provisoire d’une carte gratuite) avec une technique focalisée sur une norme (appel à l’implication). L’échantillon était constitué de 297 citoyens allemands pouvant utiliser facilement leur voiture et vivant dans des quartiers bien desservis par les transports en commun. Les participants ont été répartis au hasard dans quatre conditions (implication précédée par une carte gratuite, seulement l’implication, seulement la carte gratuite et groupe contrôle) et durent faire part de leur choix de transport pour un trajet précis et habituel (par exemple aller au travail) sur une durée de huit semaines suivie d’une période contrôle de deux semaines. En outre, les variables du modèle (la règle personnelle de réduction de l’utilisation de la voiture, les normes sociales, les coûts comportementaux ressentis et les habitudes) ont été enregistrées toutes les deux semaines. Bien que les effets globaux de l’intervention aient été faibles, les résultats montrent qu’une motivation morale est un prédicteur pertinent du choix d’un mode de transport qui peut être renforcé par une intervention portant sur l’implication précédée par un changement temporaire de la situation. A theory‐driven intervention was carried out to initiate the try‐out of a new travel mode behavior (try out taking public transport instead of car) in a sample of habitual car users (N= 297). A modified moral decision making model based on the theory of Schwartz and Howard (1981 ) served as background for the design of an intervention combining a habit‐defrosting technique (temporary gift of a free ticket) with a norm‐focused technique (plea for commitment). The sample consisted of 297 German citizens with good car access and living in areas with a convenient supply of public transportation. Participants were randomly assigned to four groups (commitment preceded by a free ticket, commitment only, free ticket only, and control) and had to report their travel mode choice for a particular, regular trip (e.g. trip to work) for a period of 8 weeks and a 2‐week follow‐up period. Additionally, model variables (personal norm to reduce car use, social norm, perceived behavioral costs, and habit) were recorded every 2 weeks. Although overall effects of the interventions were small, results indicate that a moral motivation is a relevant predictor for travel mode choices and can be stabilised by a commitment intervention preceded by a temporary change of the situation.
