Investigated the use of organizational schemes in memorizing prose. Adult organizational schemes were a function of the structure of material to be remembered and the individual's plan to recall the material. Age and sex differences were discovered in an experiment assessing developmental changes in recall plans of children and adults. (Author/DB)

Investigates age differences in selective attention in a coded visual search task where subjects were given different types of information about target location before trial onset. (Author/SS)

Three experiments obtained same-different judgments from children and adults to trace normal development of local and global processing of hierarchical visual forms. Findings indicated that reaction time was faster on global trials than local trials; bias was stronger in children and diminished to adult levels between ages 10 and 14. Reaction time…

Three studies used interspecies adoption stories to examine children's understanding of the role of birth in determining animal properties and species identity. Found that most 4- to 7-year olds could reliably judge that babies would be of the same species as birth parents, but were unable to attribute properties of adoptive parents. (Author/KB)

Fifty-eight adults with Down syndrome were assessed longitudinally over 10 years for the purpose of modeling aging-related change in cognitive function and adaptive behavior. Findings provide further evidence of changes in performance with age and include selected effects for participants who completed the study and those lost to follow-up.…

Validated models of mental addition processing by testing children and adults in a production task paradigm. Examined individual-difference relations between strategy choice parameters and criterion-related measures of ability. Found that individual differences in the apparently calculative processes that underlie numerical facility are highly…

This study investigated specific processing strengths and weaknesses among 75 readers, ages 6-10, with no oral language deficits. Unsuccessful readers of different ages showed similar information processing patterns, and differed from successful first-grade readers on short-term auditory/working memory and decoding/encoding. Three potential…

The interaction effect between two process skills (application and interpretation) and two task contexts (scientific and everyday) was investigated. Korean students (n=255), ages 13 and 15, were the subjects of this study. Results reveal that there was an apparent interaction between process skills and contexts. Sex-skill interaction and…

Differences in component processing skills of students of different ages and developmental changes over 1 year were studied for 96 students in grades 2 through 4 and 59 of them in a follow-up. Results trace the development of component processing skills and suggest a theory of the development of component skills. (SLD)

Visual and auditory processing of complex sentences was examined among 8- through 11-year-olds. Findings suggested a U-shaped learning pattern for on-line processing of restrictive relative clauses. Off-line accuracy scores showed different patterns for good and poor comprehenders. Incorrect local attachment strategy use was related to sentence…

The present study explores how suppositions which conflict with accepted beliefs are represented and reasoned about. Two studies test the predictions regarding the nature and developmental changes in children's ability to represent and reason about hypothetical or make-believe suppositions which violate their everyday knowledge and beliefs. In…

The present study employs event related potentials (ERPs) to verify the utility of using electrophysiological measures to study developmental questions within the field of language comprehension. Established ERP components (N400 and P600) that reflect semantic and syntactic processing were examined. Fifteen adults and 14 children (ages 8-13)…

Verbal-to-spatial associations in working memory may index a core capacity for abstract information limited in the amount concurrently retained. However, what look like associative, abstract representations could instead reflect verbal and spatial codes held separately and then used in parallel. We investigated this issue in two experiments on…

One of the most controversial issues in foreign language (FL) teaching is the age at which language learning should start. Nowadays it is recognized that in second language contexts maturational constraints make an early start advisable, but there is still disagreement regarding the problem of when to start or the best way to learn in foreign…

This study assessed the theory of mind (ToM) and executive functioning (EF) abilities of 124 typically developing preschool children aged 3 to 5 years in relation to whether or not they had a child-aged sibling (i.e. a child aged 1 to 12 years) at home with whom to play and converse. On a ToM battery that included tests of false belief,…
