Used a variance-partitioning procedure to identify age-related and age-invariant components of verbal and spatial memory span in 6- to 12-year olds. Concluded that verbal and spatial short-term memory appear to rely on similar processes when serial recall is required and that development in span is closely tied to increases in processing speed.…

Three experiments examined whether and how the strength of original information and strength of misleading information influenced 3- to 5-year olds' memory for an event. Findings indicated that children exposed to the event once reported more misled details than those seeing the event multiple times, and were just as susceptible to misleading…

Three experiments demonstrated that increasing the length of a mobile serial list impaired 6-month olds' memory for serial order. Findings indicated that the primacy effect was absent on a 24-hour delayed recognition test and was exhibited on a reactivation test, adding to growing evidence that young infants possess two functionally distinct…

Two studies examined developmental patterns in understanding physical and social transitivity in 6- to 11-year olds. Findings revealed no significant correlations between social judgments and judgments concerning length. Results suggested that children possess two distinct strategies for making transitive judgments that correspond to the logical…

Trained fast- and slow-namer groups of poor-reading second graders to read words using different training regimes. Found that slow namers were particularly disadvantaged compared to fast namers when trained with word-level units. Children showed poorer retention following onset/rime training compared to other types. They showed the best…

Three experiments assessed memory skills in good and poor comprehenders, matched for decoding skill. Found that poor comprehenders showed normal sensitivity to phonological manipulations but that their recall of abstract words was poor. Poor comprehenders achieved normal spatial-memory span, but had impaired verbal-memory spans. (Author/KB)

Examined effects of misleading or inconsistent post-event information on 7-year olds' recollections. Misinformation was administered on one or three occasions two days after learning a target game. Found that three weeks later, even criterion-learned information could be affected detrimentally by misinformation exposure. Children given…

Two experiments examined the influence of phonological and semantic processes on 4- to 6-year olds' ability to learn to read words. Results indicated that children learned phonetic cues better than control cues and that learning was influenced by both the phonetic properties of the cue and the imageability of the words used. (Author/KB)

Four experiments examined influence of task demands on 5- to 9-year olds' and adults' reading strategy. Results showed that less-skilled readers predominantly used simple grapheme-phoneme-level correspondences in reading isolated unfamiliar items. Skilled readers more likely adopted an analogy strategy. The "clue word" technique yielded higher…

Investigated the specificity of reading-disabled children's deficits in working memory capacity. Found that reading-disabled 10-year-olds performed worse than normal-reading children, matched for chronological age and reading age, on all measures of working memory capacity. Their poorer performance seemed to be due to a general lack of capacity…

Two studies compared children's knowledge about the letters in their name with knowledge of other letters. Findings indicated that Australian first graders and U.S. kindergartners and preschoolers had superior knowledge of letter-name, but not letter-sound, for first letter of their first name. Also, U.S. preschoolers were better at printing the…

Examined the relationship between phonological sensitivity and letter knowledge in 4- and 5-year-olds in a one-year longitudinal study. Found that phonological sensitivity predicted letter knowledge growth, and letter knowledge predicted phonological sensitivity growth, when controlling for age and oral language abilities. Also found that the…

Three studies examined linguistic factors influencing preschooler's phonemic awareness task performance. Results indicated no performance differences between fricatives and stops. Subjects were more likely to mistakenly judge that syllables began with a target phoneme when the initial phoneme differed from the target only in voicing than when it…

Habituated 180 neonates to white lights of varying luminance and tested for recovery of habituation to green, yellow, or red lights varying in excitation purity. Found that newborns discriminated chromatic stimuli from white only when excitation purity exceeded levels much higher than those for adults. Results reinforce view that neonates' vision…

Five experiments examined matching to sample procedures among preschoolers. Results indicated that children selected taxonomic comparisons more often than thematic comparisons, independent of age, gender, instructions, order of trial type, specificity of feedback, presence of unrelated third comparisons, and level of taxonomy. Instructions to…
