The current research aims at constructing a developmentally sensitive mindreading scale (i.e., battery of tasks measuring different aspects ability in children from 1 to 3.5 years age). Over 300 Polish were tested six-month intervals with 48 designed measure (for total six measurement occasions, T1-T6; NT1 = 357; MageT1 52,30 weeks; SD 1,73; 201 (56%) boys, 156 (44%) girls). Using latent trait ...

We report a longitudinal study investigating developmental changes in the structure of attention engagement during early infancy. Forty-three infants were observed monthly from 2 to 4 months. Attention engagement was assessed from play interactions with parents, using a coding system developed by Bakeman and Adamson (1984). The results indicated a developmental transition in attention engagemen...

Joint attention is pivotal to the development of complex social skills and language, and many individuals with Autism Spectrum Disorders display deficits in this domain. Behavioral interventions targeting joint attention are evidenced to be effective in teaching these skills to young children with autism, but these treatments have traditionally been implemented by adults in structured settings....

Recent studies have attempted to understand the processes involved in joint attention because of its relevance to both atypical and normal development. Data from a recent study of young children with autism suggests that performance on a delay nonmatch to sample (DNMS) task associated with ventromedial prefrontal functions, but not an A-not-B/delayed response task associated with dorsolateral p...

We investigated whether people take into account an interaction partner's attentional focus and whether they represent in advance their partner's part of the task when planning to engage in a synchronous joint action. The experiment involved two participants planning and performing joint actions (i.e., synchronously lifting and clinking glasses), unimanual individual actions (i.e., lifting and ...
