Studied text interpretation in four experiments with second and fourth graders, manipulating several story variables. Found that both groups were skilled at providing two text interpretations, although second graders were more likely than fourth graders to use extra-story information in their second interpretations. Subjects' first interpretations…

Studied whether kindergartners and first graders spell a sequence of phonemes with the corresponding consonant letter rather than spelling the sequence alphabetically with a consonant letter followed by a vowel. Found that children made letter-name spelling errors, especially when the consonant and vowel formed a complete syllable, showing that…

Studied relationships among short-term memory, processing speed, sequencing ability, and long-term memory information retrieval in 7-year-olds. Found that when reading ability was controlled, arithmetic ability was best predicted by processing speed, with short-term memory accounting for no further unique variance. Children with arithmetic…

Examined digit and word dichotic listening in children in kindergarten and again one year later. Found that in the second digit test, between-ears performance difference decreased; overall performance increased. Between-ear differences across the two word tests were not significant, but overall performance improved over time. Age changes in the…

Examined preschoolers' beliefs about relationships between effort, interest, and recall; assessed actual effort and recall under different interest levels. Found that children believed recall increases with effort and interest, and that interest influences effort. Children's actual interest influenced effort, but effort was unrelated to recall.…

Investigated effects of sparse versus real contexts on understanding abstract mathematical concepts regarding the interpretation of linear graphs. Results of four experiments showed that a sparse context facilitated understanding of abstract concepts more than real contexts. Activation of abstract logic-mathematical knowledge structures was…

Examined effects of training in sequencing pairs of visual stimuli on subsequent six-stimuli or five overlapping two-stimuli sequencing. Subjects were 3- and 4-year-olds. Found that few succeeded with untrained two- and six-stimulus sequences derivable from the two-stimulus training, but when given training on only the overlapping sequences,…

Infants were familiarized with geometric forms and were then tested with a novel form paired with the familiar one. Compared to infants who had longer looks at the display, those who had shorter looks demonstrated more broadly distributed looks, showed more looks and shifts, and inspected more stimulus areas; and their shifts included more…

Sought to establish a valid computer measurement technique for educational assessment applications. Similarities and differences in performance on visual discrimination tasks for young children of normal development and adolescents with severe mental retardation were analyzed using multiple testing procedures. Found differences in the two groups…

Young children and adults looked at 400 pictures of common objects and were asked to name the object, indicate their familiarity with the object, and state how complex the object would be to draw. Normative data indicated that children and adults differed in the most frequent name assigned and the number of alternative names used. (BC)

Children were presented with a related-word triplet (horse, pig, cow) with or without accompanying setting, or place, information (farm). Children were later given a retrieval cue from the first two words of the triplet and asked to recall the third word. Found that place information presented at acquisition and retrieval facilitated children's…

Presented 9-month-old infants with slides of drawings of pigs and rabbits, and tested the relative success of two auditory accompaniments in facilitating subsequent categorization of the slides. Found that infants paid more attention to presentations when they were accompanied by sound (words or tones) rather than musical tones, and paid more…

Tested visual-perceptual, attentional, and visual-motor skills of 16 school-age children who had been born pre-term and "healthy," and 16 who had been born full-term. Found that compared to subjects born full-term, pre-term subjects performed well on most visual perception tasks, but less well on visual search and visual-motor tasks. (EAJ)

Examined 80 children in second and fourth grades on melodic and rhythmic discrimination and classification tasks. Found evidence to support the existence of internal representations of tonality and meter in both groups, as well as evidence of a developmental effect for the classification task. (EAJ)

Measured cognitive processing time, imagery skill, and spatial memory span of 128 children and adults, ages 8 to 20 years. Found that performance on spatial memory span tasks was largely predicted by imagery skill, which in turn was strongly linked to processing time; age was much less of a predictor in both cases. (EAJ)
