  • Attenuated selective attention during visual perspective taking in autism

    Open Access•Leonie Polzer, Nico Bast et al.•ARTICLE•Journal of Child Psychology and…•2026

    BACKGROUND: Altered social cognition in autism may be influenced by difficulties in domain-general functions, such as selective attention. Here, we manipulated the requirement for selective attention during a visual perspective taking (VPT) task and used neurophysiological indices to delineate underlying mechanisms. METHODS: 43 autistic and 38 neurotypical children and youth completed a VPT paradigm. Participants' and an avatar's perspectives wer…

  • Complex, low‐intensity, individualised naturalistic developmental behavioural intervention in toddlers and pre‐schoolers with autism spectrum disorder

    Open Access•Christine M Freitag, Marietta Kirchner et al.•ARTICLE•Journal of Child Psychology and…•2025

    BACKGROUND: Naturalistic developmental behavioural interventions (NDBI) may improve social communication in toddlers/pre-school aged children with autism spectrum disorder (ASD). Here, we study efficacy of the low-intensity, complex NDBI 'Frankfurt Early Intervention Program for ASD' (A-FFIP) over 1 year by a confirmatory phase-III, prospective, randomised, controlled, parallel-group study with two treatment arms over four centres. METHODS: Main …

  • Capturing change in restricted and repetitive behaviour in preschoolers with ASD

    Open Access•Naisan Raji, Janina Kitzerow‐Cleven et al.•ARTICLE•Journal of Child Psychology and…•2025

    BACKGROUND: Restricted and repetitive behaviour (RRB) in autism spectrum disorder (ASD) can be assessed by different measures, which diverge in item quantity, dimensionality or source of information. However, change sensitivity has not been systematically investigated among commonly used measures, albeit its importance for clinical trials and longitudinal studies. METHODS: Longitudinal data resulting from behavioural observation (Autism Diagnosti…
