A prominent theoretical view is that the brain is inherently predictive [1, 2] and that prediction helps drive the engine of development [3, 4]. Although infants exhibit neural signatures of top-down sensory prediction [5, 6], in order to establish that prediction supports development, it must be established that deficits in early prediction abilities alter trajectories. We investigated predict...

OBJECTIVE The purpose of this study was to explore the effects of a powered mobility riding toy on the participation behaviors of young children with complex developmental delays. METHOD A single-subject withdrawal design was used to study the effects of powered mobility on child-initiated movement occurrences, initiation of contact with others, and affect. The participants were two young chi...

Many species delay development unless particular environments or rare disturbance events occur. How can such a strategy be favoured over continued development? Typically, it is assumed that continued development (e.g. germination) is not advantageous in environments that have low juvenile/seedling survival (mechanism 1), either due to abiotic or competitive effects. However, it has not previous...

Community-based peer social networks of young boys with developmental delays and parental arranging and monitoring of their child's peer contacts were examined. Comparisons were made to matched groups of children who were developing typically and to children with communication disorders. Results showed more limited peer social networks for both groups of children with disabilities based primari...

CASE Peter’s parents made an appointment with his pediatrician because of their increasing concern about his refusal to speak. After approximately 2 weeks following the start of a new preschool, Peter, 4 years 10 months old, refused to speak to other children or the teacher. During the first week of school, he found it difficult to separate from his mother or father. He would cry and cling to t...
