Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, also known as "frontier words" (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar.…

Expressive language is an important skill to develop in children with intellectual disabilities. It not only aids in decreasing the likelihood of challenging behaviors from occurring but also aids in increasing the individuals independence and assistance in them becoming successful members of society. No previous studies have examined the…

Asking children to gesture while being taught a concept facilitates their learning. Here, we investigated whether children benefitted equally from producing gestures that reflected speech (speech-gesture matches) versus gestures that complemented speech (speech-gesture mismatches), when learning the concept of palindromes. As in previous studies,…

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, a.k.a. "frontier words" (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar. However,…

Autism is defined as a neuro-developmental disorder and is characterized by a chronic and severe impairment in social relations. Children with autism have limited development in both verbal language and non-verbal language, relative to eye contact, gestures, facial expression, and body language. The cause of autism is not known; however, genetic…

Educational films for children aim to impart knowledge about a certain topic. In the present paper, it is investigated how much and what kind of information children can remember from educational films and how knowledge acquisition through films could be enhanced. The studies described here were designed to test the hypothesis that children's…

This study describes a longitudinal design (following subjects described in Rutherford & Rogers [2003, "Journal of Autism and Developmental Disorder", 33, 289-302]) to test for predictors of pretend play competence in a group of children with autism. We tested the hypothesis that developmental change in pretend play performance can be predicted by…

Tests Ausubel's (1960) subsumption theory of learning in the context of children's use of causal and logical connectives. Predicts that the acquisition of prior cognitive structure organizers would facilitate the learning and retention of subsequently presented concepts and logical operations and lead to a decrease of syncretic reasoning and…
