Cheong, Janice M. Y.; Walker, Zachary M.; Rosenblatt, Kara – International Journal of Disability, Development and Education, 2017
Mathematics is an important aspect of daily life. Basic numeracy skills are needed to accomplish everyday tasks. However, research regarding the relationship between cognitive ability, mental age, and basic numeracy skills for children with intellectual disability (ID) is scarce. This research study investigated the correlation between…

Schuchardt, Kirsten; Maehler, Claudia; Hasselhorn, Marcus – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Recent studies indicate that children with intellectual disabilities have functional limitations primarily in the phonological loop of working memory (Baddeley, 1986). These findings are indicative of a specific structural deficit. Building on this research, the present study examines whether it is possible to identify specific phonological…

Schuchardt, K.; Gebhardt, M.; Maehler, C. – Journal of Intellectual Disability Research, 2010
Background: In recent years, there has been increased research interest in the functioning of working memory in people with intellectual disabilities. Although studies have repeatedly found these individuals to have weak working memory skills, few investigations have distinguished between different degrees of intellectual disability. This study…

Loveland, Katherine A.; Bachevalier, Jocelyne; Pearson, Deborah A.; Lane, David M. – Neuropsychologia, 2008
We used neuropsychological tasks to investigate integrity of brain circuits linking orbitofrontal cortex and amygdala (orbitofrontal-amygdala), and dorsolateral prefrontal cortex and hippocampus (dorsolateral prefrontal-hippocampus), in 138 individuals aged 7-18 years, with and without autism. We predicted that performance on…

Dahlgren, Svenolof; Sandberg, Annika Dahlgren – Autism: The International Journal of Research and Practice, 2008
Referential communication was studied in children with autism spectrum disorder (ASD) including children with autism and Asperger syndrome. The aim was to study alternative explanations for the children's communicative problems in such situations. Factors studied were theory of mind, IQ, verbal ability and memory. The main results demonstrated…

Lempers, J.; And Others – Merrill-Palmer Quarterly, 1987
Compares gifted preschool boys and girls with both a CA (Chronological Age)-matched group and an MA (Mental Age)-matched group on their performance on a spatial projective task, a cognitive perspective-taking task, and an affective perspective-taking task. The data seem to support the hypothesis that psychometric brightness implies cognitive…

Silverstein, A. B.; And Others – Psychology in the Schools, 1981
A series of item analyses of the Concept Assessment Kit Conservation (Goldschmid) conducted for a sample of educable mentally retarded children showed that the probability of a correct response differed from task to task. Evidence indicated that the order of difficulty of the tasks resembled that for nonretarded children. (Author)

Reviews the major contributions of Alfred Binet. Explains why the fame of the Binet-Simon Intelligence Scale was so long lasting whereas that of his other contributions was so fleeting. Discusses implications of his contributions for current efforts to formulate unified theories of cognition and cognitive development. (Author/GLR)

Green, Sarah; Pring, Linda; Swettenham, John – British Journal of Developmental Psychology, 2004
This study assessed theory of mind understanding in children with congenital profound visual impairment (CPVI): children who have had no access to visual information throughout development. Participants were 18 children with CPVI and no other impairments, aged between 5 and 11 years, and 18 children with normal vision, matched individually on…
