Lost in the move? Secondary task performance impairs tactile change detection on the body

Change blindness, the surprising inability of people to detect significant changes between consecutively-presented visual displays, has recently been shown to affect tactile perception as well. Visual change blindness has been observed during saccades and eye blinks, conditions under which people’s awareness of visual information is temporarily suppressed. In the present study, we demonstrate change blindness for suprathreshold tactile stimuli resulting from the execution of a secondary task requiring bodily movement. In Experiment 1, the ability of participants to detect changes between two sequentially-presented vibrotactile patterns delivered on their arms and legs was compared while they performed a secondary task consisting of either the execution of a movement with the right arm toward a visual target or the verbal identification of the target side. The results demonstrated that a motor response gave rise to the largest drop in perceptual sensitivity (as measured by changes in d′) in detecting changes to the tactile display. In Experiment 2, we replicated these results under conditions in which the participants had to detect tactile changes while turning a steering wheel instead. These findings are discussed in terms of the role played by bodily movements, sensory suppression, and higher order information processing in modulating people’s awareness of tactile information across the body surface.     

Das Asperger-Syndrom bei Erwachsenen

Herr F., 35 Jahre alt, wendet sich per E-Mail an die Kinderklinik mit der Frage, ob eine diagnostische Abkl?rung bei uns m?glich sei, da er im Erwachsenenbereich keine Ansprechperson gefunden habe. Durch eine Internetrecherche sei er auf das Asperger-Syndrom gesto?en. Seit seiner Kindheit habe er sich bereits gefragt, was bei ihm nicht stimme, warum er ,,anders“ sei und warum es seinen Mitschülern immer so leicht gefallen sei auf andere zuzugehen, ,,Small Talk“ zu führen oder Kontakte aufrecht zu erhalten. Er hingegen habe damit immer massive Schwierigkeiten gehabt, habe soziale Zusammenh?nge oft nicht begriffen beziehungsweise die Gedanken, Absichten oder Gefühle anderer nicht entschlüsseln k?nnen. Obwohl er dies erkennt, konnte er es bisher nicht bewusst ?ndern, was in weiterer Folge zu einer depressiven Verstimmung mit Rückzug geführt hat. In der weiteren Exploration stellt sich heraus, dass Herr F. alleine wohnt, aber immer noch finanziell beziehungsweise im Alltag von seinen Eltern unterstützt wird. Derzeit hat er keine Beziehung, die vorangegangene Partnerschaft ging wegen Kommunikationsproblemen in die Brüche, worunter er sehr leidet. Aufgrund seiner speziellen Interessen studierte Herr F. Astrophysik und technische Mathematik und schloss beide Studien mit Auszeichnung ab. Seither hat er in etwa 20 verschiedenen Jobs gearbeitet, die meist nicht seiner Qualifikation entsprachen. Das Arbeitsverh?ltnis wurde jeweils beendet, da Herr F. von den sozialen Anforderungen massiv überfordert war. Seine Freizeit verbringt Herr F. alleine, bet?tigt sich im Internet in Chatrooms, liest Fachliteratur und hat eine vollst?ndige Sammlung an Sportfachzeitschriften seit dem Jahr 1995, die er in einer bestimmten Ordnung aufbewahrt und deren Inhalte er so gut wie auswendig kennt.

The rhyming skills of deaf children educated with phonetically augmented speechreading

Two experiments investigated whether profoundly deaf children's rhyming ability was determined by the linguistic input that they were exposed to in their early childhood. Children educated with Cued Speech (CS) were compared to other deaf children, educated orally or with sign language. In CS, speechreading is combined with manual cues that disambiguate it. The central hypothesis is that CS allows deaf children to develop accurate phonological representations, which, in turn, assist in the emergence of accurate rhyming abilities. Experiment 1 showed that the deaf children educated early with CS performed better at rhyme judgement than did other deaf children. The performance of early CS-users was not influenced by word spelling. Experiment 2 confirmed this result in a rhyme generation task. Taken together, results support the hypothesis that rhyming ability depends on early exposure to a linguistic input specifying all phonological contrasts, independently of the modality (visual or auditory) in which this input is perceived.     

Global Collaborative Team Performance for the Revision of the International Classification of Diseases: A Case Study of the World Health Organization Field Studies Coordination Group

Background/Objective: Collaborative teamwork in global mental health presents unique challenges, including the formation and management of international teams composed of multicultural and multilingual professionals with different backgrounds in terms of their training, scientific expertise, and life experience. The purpose of the study was to analyze the performance of the World Health Organization (WHO) Field Studies Coordination Group (FSCG) using an input-processes-output (IPO) team science model to better understand the team's challenges, limitations, and successes in developing the eleventh revision of the International Classification of Diseases (ICD). Method: We thematically analyzed a collection of written texts, including FSCG documents and open-ended qualitative questionnaires, according to the conceptualization of the input-processes-output model of team performance. Results: The FSCG leadership and its members experienced and overcame numerous barriers to become an effective international team and to successfully achieve the goals set forth by WHO. Conclusions: Research is necessary regarding global mental health collaboration to understand and facilitate international collaborations with the goal of contributing to a deeper understanding of mental health and to reduce the global burden of mental disorders around the world.     

Insertion des femmes dans un métier « masculin » : transfert d’acquis d’expériences et stratégies identitaires

Entering a male-dominated occupation is favorable to the study of identity strategies. Based on a research among thirty female bus drivers, this article aims to demonstrate that the transfer – in the professional sphere – of knowledge, abilities, attitudes and values acquired in other spheres and times of socialization, is an important component of such strategies. Referred to the model of an active and plural socialization (Baubion-Broye & Hajjar, 1998 ; Almudever & al, 1999) and to Dubar’s distinction (2000) of a biographical and a relational transaction, the content analysis of the female bus drivers interviews allowed : a) to emphasize the relevance of using transfer of experiences acquisitions as an indicator of biographical transaction; b) to establish the links between transfer processes and gender positioning (as an indicator of relational transaction); c) to define three types of identity strategies distinguished by their level of transfer activation.     

Multi-Informant Assessments of Adolescent Social Anxiety: Adding Clarity by Leveraging Reports from Unfamiliar Peer Confederates

Adolescent social anxiety (SA) assessments often include adolescent and parent reports, and low reporting correspondence results in uncertainties in clinical decision-making. Adolescents display SA within non-home contexts such as peer interactions. Yet, current methods for collecting peer reports raise confidentiality concerns, though adolescent SA assessments nonetheless would benefit from context-specific reports relevant to adolescent SA (i.e., interactions with unfamiliar peers). In a sample of 89 adolescents (30 Evaluation-Seeking; 59 Community Control), we collected SA reports from adolescents and their parents, and SA reports from unfamiliar peer confederates who interacted with adolescents during 20-minute mock social interactions. Adolescents and parents completed reports on trait measures of adolescent SA and related concerns (e.g., depressive symptoms), and adolescents completed self-reports of state arousal within mock social interactions. Adolescents’ SA reports correlated with reports on parallel measures from parents in the .30s and with peer confederates in the .40s to .50s, whereas reports from parent-confederate dyads correlated in the .07 to .22 range. Adolescent, parent, and peer confederate SA reports related to reports on trait measures of adolescent SA and depressive symptoms, and distinguished Evaluation-Seeking from Community Control Adolescents. Confederates’ SA reports incrementally predicted adolescents’ self-reported SA over and above parent reports, and vice versa, with combined Rs ranging from .51 to .60. These combined Rs approximate typical correspondence levels between informants who observe adolescents in the same context (e.g., mother-father). Adolescent and peer confederate (but not parent) SA reports predicted adolescents’ state arousal in social interactions. These findings have implications for clarifying patterns of reporting correspondence in clinical assessments of adolescent SA.
