A variation of the social context in the warm-up period influences 18-month-olds’ imitation

The present study aimed to investigate how the prior social disposition of a model in a warm-up period influences 18-month-old infants’ subsequent imitation. Infants were randomly assigned to an interactive and social warm-up period (n = 19) or a non-interactive and non-social warm-up period (n = 19) with the model prior to the imitation task. They then participated in an imitation task with different types of actions: novel means actions, arbitrary vs. functional actions and necessary vs. unnecessary actions. An additional social warm-up control group (n = 14) and a non-social warm-up control group (n = 14) were recruited to assess the spontaneous production of the target actions in the absence of the demonstration. The results showed that infants in the experimental groups performed significantly more target actions than infants in the control groups, showing an imitation effect. Furthermore, the results of the experimental groups showed that the overall imitation performance of the target actions was higher in the social condition than in the non-social condition. This imitation enhancing effect of the social warm-up period held true for the novel means actions and functional vs. arbitrary actions, however not for the necessary vs. unnecessary actions. Implications of the results for theory and future studies are discussed in terms of infants’ social motivation and its relation to infants’ imitative behavior

Developmental Speech and Language Disorders According to ICD-11

Sprach- und Sprechstörungen kommen bei zahlreichen Kindern vor und werden in der ICD-11 analog zur ICD-10 als Entwicklungsstörungen im Kapitel 6 (Psychische, Verhaltens- und Entwicklungsstörungen) klassifiziert. International sind bislang die ICD-10-Kriterien nicht von allen Professionen, die sich mit Sprach- und Sprechstörungen klinisch oder im Rahmen der Forschung beschäftigen, akzeptiert. Sie werden einerseits als zu wenig differenziert hinsichtlich der unterschiedlichen Sprachkomponenten vonseiten der Linguistik, Sprachtherapie oder Logopädie erlebt. Zum anderen wird die unklare Abgrenzung organisch bedingter Sprach- und Sprechprobleme von der Sprachentwicklungsstörung vonseiten der Medizin teilweise kritisch bewertet. In dem vorliegenden Artikel wird deshalb einerseits die Klassifikation von Sprach- und Sprechproblemen und -störungen in der ICD-11 im Vergleich zur ICD-10 vorgenommen. Wesentlich erscheint hier die in der ICD-11 neu eingeführte Differenzierung in „primäre“ und „sekundäre“ Neuroentwicklungsstörungen. Zum anderen erfolgt aber auch eine Auseinandersetzung mit dem DSM-5 sowie anderen Klassifikationsvorschlägen vonseiten der englischsprachigen Sprachtherapie (CATALISE-2) und der deutschsprachigen Pädaudiologie („phonologische Wahrnehmungsstörung“) sowie der Vorschlag einer Ergänzung der aktuellen ICD-11-Klassifikation hinsichtlich konkreter sprachlicher Einschränkungen bei einem Kind mit Sprachentwicklungsstörung, basierend auf einer ausführlichen Diagnostik. Wir hoffen, mit dem Artikel so den Weg für eine berufsübergreifende Klassifikation von Sprach- und Sprechstörungen nach ICD-11 zu bahnen, damit perspektivisch alle Berufsgruppen, die Diagnostik und Therapie der betroffenen Personen anbieten, eine vergleichbare Terminologie verwenden. Diese vergleichbare Terminologie soll sowohl die klinische Versorgung verbessern als auch die unterschiedlichen Forschungsansätze und -richtungen vergleichbarer machen.In ICD-11, similar to ICD-10, speech and language disorders are classified as neurodevelopmental disorders, which are part of ICD-11 Chapter 6 (Mental, Behavioural and Neurodevelopmental Disorders). The ICD-10 criteria were not well accepted by many professionals in research and clinic who work with children with speech and language disorders. Especially linguists and speech and language therapists see ICD-10 as too crude and lacking specification of individual language problems. Medical professions in turn criticize the missing aspect of organically caused speech and language problems. This paper presents the classification of speech and language problems or disorders according to ICD-11 compared to ICD-10. One essential aspect lies in the differentiation between “primary” and “secondary” neurodevelopmental disorders. In addition, we compare and discuss other recent classification approaches, such as DSM-5, CATALISE-2, and the classification “Auditory Processing Disorder” by pediatric audiologists. We present a classification approach based on ICD-11, supplemented by an additional specification of the respective impaired speech or language area in the individual child and based on a thorough speech and language assessment. We thus hope to pave the path for an interdisciplinary classification of speech and language disorders according to ICD-11, our aim being to establish a common terminology that can be used by all professions. We expect this common terminology to improve clinical care and to allow for the integration and comparability of speech- and language-related research efforts

Temporal progression of pupil dilation and gaze behavior to emotion expressions in preschoolers with autism spectrum disorder

Abstract Previous work has shown divergent pupil dilation (PD) and gaze behavior in individuals with autism spectrum disorder (ASD), which may relate to the development of social difficulties in early life. Here, we investigated temporal dynamics of both phenotypes during naturalistic videos of a person displaying facial emotion expressions in 61 autistic and 61 non-autistic preschoolers. PD was segmented into three serial time components derived from a principal component analysis. Growth curve analysis was applied to analyze changes in looking time on eye and mouth regions over time. Groups did not differ in PD time components. Growth curve analysis revealed initially shorter looking times on the eyes and longer looking times on the mouth in autistic versus non-autistic preschoolers. However, a reversion of this pattern was observed over time, suggesting a delayed compensatory increase in eye attention during prolonged viewing periods in autistic children. Positive and negative associations of PD components and gaze behavior over time indicated a dynamic temporal relationship during emotion viewing. Our findings emphasize the need to apply time-sensitive measures in ecologically valid research, which may index etiological mechanisms of social difficulties in ASD

Study protocol of the multi-centre, randomised controlled trial of the Frankfurt Early Intervention Programme A-FFIP versus early intervention as usual for toddlers and preschool children with Autism Spectrum Disorder (A-FFIP study)

Background: Naturalistic developmental behavioural interventions (NDBI) have been shown to improve autism-specific symptoms in young children with Autism Spectrum Disorder (ASD). NDBI approaches, such as the ASD-specific Frankfurt Early Intervention Programme for ASD (A-FFIP), are based on ASD-specific developmental and learning aspects. A-FFIP is a low-intensity intervention which can easily be implemented in the local health care/social welfare system. The aim of the present study is to establish 1-year efficacy of the manualised early intervention programme A-FFIP in toddlers and preschool children with ASD. It is hypothesised that A-FFIP will result in improved ASD-specific symptoms compared to early intervention as usual (EIAU). Child- and family-specific secondary outcomes, as well as moderators and mediators of outcome, will be explored. Methods/design: A prospective, multi-centre, parallel-group, randomised controlled, phase-III trial comparing A-FFIP versus EIAU. A total of 134 children (A-FFIP: 67, EIAU: 67) aged 24–66 months at baseline assessment meeting the criteria for ASD (DSM-5) will be included. The primary outcome is the absolute change of the total score of the Brief Observation of Social Communication Change (BOSCC-AT) between baseline (T2) and 1-year follow-up (T6). The treatment effect will be tested, adjusted for relevant covariates applying a mixed model for repeated measures. Secondary outcomes are BOSCC social communication and repetitive-behaviour scores, single ASD symptoms, language, cognition, psychopathology, parental well-being and family quality of life. Predictors, moderators and mediating mechanisms will be explored. Discussion: If efficacy of the manualised A-FFIP early intervention is established, the current study has the potential to change clinical practice strongly towards the implementation of a low-intensity, evidence-based, natural early intervention in ASD. Early intervention in ASD requires specialist training, which subsequently needs to be developed or included into current training curricula.
