Background: When mathematical knowledge is expressed in general language, it is called verbalized mathematics. Previous studies on verbalized mathematics typically paid attention to mathematical vocabulary or educational practice. However, these studies did not exclude the role of symbolic mathematics ability, and almost no research has focused on…

Working memory (WM) impairments might amplify behavioural difference in genetic syndromes. Murine models of Rubinstein-Taybi syndrome (RTS) evidence memory impairments but there is limited research on memory in RTS. Individuals with RTS and typically developing children completed WM tasks, with participants with RTS completing an IQ assessment and…

Cognitive reserve relies on the ability to effectively cope with aging and brain damage by using alternate processes to approach tasks when standard approaches are no longer available. In this study, the issue if creativity can predict cognitive reserve has been explored. Forty participants (mean age: 61 years) filled out: the Cognitive Reserve…

Research was conducted to compare evidence of implicit processing in children and adults. Implicit processing was defined as inductive cognitive activities which enable people to abstract complex knowledge from the environment. The knowledge acquired is tacit; it guides subjects' behavior in various situations without the subjects necessarily…

Male infant vocalizations were studied as a function of age. (JMB)

Compares the effects of language intervention over a one-year period on two groups of young children with delayed language: one group with cognitive skills markedly above their language level, and the other group with similar delays in cognitive and language skills. (28 references) (GLR)

Studied the development of speech act comprehension in 36 retarded and 36 nonretarded children at the developmental ages of five, seven, and nine years. Retarded and nonretarded individuals followed the answer obviousness rule and used the contextual and linguistic clues available to respond to yes-no interrogative sentences. (RJC)

Describes three experiments that tested autistic children's nonverbal and verbal categorization abilities. Concludes that autistic children do not suffer a specific cognitive deficit in ability to categorize and form abstract concepts. (HOD)

Confirms a trend in an earlier study for high-contact Aboriginals to perform on classification tests at about the same level as white children in a similar environment, despite the markedly lower verbal intelligence quotient scores of Aboriginal children. (RJ)

This study examined the relationship between adaptive functioning and intellectual functioning in 18 children with autism and mental retardation and 20 children with mental retardation. The children with autism showed significantly more impairment in adaptive behavior composite scores, verbal reasoning abilities, socialization skills, and…

Differences in 3-month-old infants' vocal responsiveness to vocal-visual stimulation by mothers and strangers has been shown to be related to performance on both the Stanford-Binet at 3 years of age and the Illinois Test of Psycholinguistics at 5 years of age. The present retesting of 12 of the original 14 normal, first-born male subjects, now 12…

This paper discusses how the role of instructors changes as young learners advance along a mastery continuum, or a process of transition from an initial novice to an eventual expert status in the learning of a skill. Four stages along this continuum are: (1) acquisition, in which the learner does not know the task; (2) early consolidation, in…

Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…
