Reading disability (RD) may be characterized by reduced print-speech convergence, which is the extent to which neurocognitive processes for reading and hearing words overlap. We examined how print-speech convergence changes from children (mean age: 11.07±0.48) to adults (mean age: 21.33±1.80) in 86 readers with or without RD. The participants were…

An object's mental representation includes not just visible attributes but also its nonvisible history. The present studies tested whether preschoolers seek subtle indicators of an object's history, such as a mark acquired during its handling. Five studies with 169 children 3-5 years of age and 97 college students found that children (like adults)…

This study examined the contribution of executive function (EF) and multiple aspects of fine motor skills to achievement on 6 standardized assessments in a sample of middle-socioeconomic status kindergarteners. Three- and 4-year-olds' (n = 213) fine and gross motor skills were assessed in a home visit before kindergarten, EF was measured at fall…

Investigates the asserted differences in reasoning between adults and second, fourth, and sixth graders in a manipulation of variables task using class inclusion and story problems with common everyday situations. Results are discussed in terms of sensible reasoning and problem-solving skills. (CM)

Presents two experiments which measured latencies in a picture-word interference task to assess semantic processing. Results suggest that picture-word interference is partly semantically based and that children and adults experience an equivalent amount of semantic interference. (Author/SDH)

Although adults and children were found to be equally accurate in their initial estimates of recall, adults used that information more skillfully in choosing what to study and deciding when they had studied sufficiently. (Author/JMB)

According to Humean framework, relations are judged to be causal to extent that they are characterized by regularity, continuity, and covariation among college students and college-bound 11- and 14-year-olds. Presents subjects with information about one of the following indices: potential causal factor covaried with effect and potential causal…

Examines the relative effectiveness of organizational strategy use at study versus test in a single-trial, free-recall learning task among 90 subjects drawn from second grade, sixth grade, and college levels. Developmental increases in performance were observed for the dependent measures of correct recall, study-trial organization, test-trial…

The degree to which judgments of ability, effort, and performance conform to the prediction of Harold Kelley's theory of causal schemata was examined at four age levels (kindergarten, third grade, fifth grade and college). Author/MP)

The hypothesized central role of cognitive development in resolving moral dilemmas was examined in sixth grade and college-age females. Results indicated that sophisticated cognitive operations are a prerequisite to advanced moral judgments. (ST)

First, second, third, sixth, and ninth graders and college students were presented with 4 different tasks of surface-volume dissociation in order to see whether or not the conservation of one of these properties would wrongly induce a belief in the conservation of the other. (Author/JMB)

Geometric matrix problems were presented to 11- and 14-year-olds and adults to investigate latency to solution as a function of number of elements (1-3) and of transformations (0-2) that had to be considered for correct solution. At all ages latencies increased as the number of elements and number of transformations increased. (Author/DB)
