We examined whether children's ability to integrate speech and gesture follows the pattern of a broader developmental shift between 3- and 5-year-old children (Ramscar & Gitcho, 2007) regarding the ability to process two pieces of information simultaneously. In Experiment 1, 3-year-olds, 5-year-olds, and adults were presented with either an…

Although a fair amount is known about young children's production of negation, little is known about their comprehension. Here, we focus on arguably the most complex basic form, denial, and how young children understand denial, when it is expressed in response to a question with gesture, single word, or sentence. One hundred twenty-six children in…

Educational television for young children often combines factual content with fantasy. In 2 experiments, we examined 3- to 5-year-olds' reality judgments and the implications for their learning. In the 1st study, 145 children watched 3 clips featuring (respectively) a Hispanic, a Chinese American, and an Anglo character. Responses indicated…

There are many reasons to be curious about the way people learn, and the past several decades have seen an explosion of research that has important implications for individual learning, schooling, workforce training, and policy. In 2000, "How People Learn: Brain, Mind, Experience, and School: Expanded Edition" was published and its…

Four- and five-year-olds completed two sets of tasks that involved reasoning about the temporal order in which events had occurred in the past or were to occur in the future. Four-year-olds succeeded on the tasks that involved reasoning about the order of past events but not those that involved reasoning about the order of future events, whereas…

Background: Little is known about trajectories of cognitive functioning as individuals with Williams syndrome (WS) move though adulthood. Method: The present study investigated cognitive, linguistic and adaptive functioning in adults with WS aged 19-55 years, using both cross-sectional and longitudinal approaches. Results: Data from the…

The development of mental imagery in relation to the comprehension of concrete proverbs (e.g., "one rotten apple spoils the barrel") was examined in children, adolescents, and adults who were ages 11 to 29 years old (n = 210). The findings indicated that age-related changes occurred in mental imagery and in proverb comprehension during the years…

Two studies investigated the relationship between learning names and learning concepts in preschool children. More specifically, we focused on the relationship between learning the names and learning the intended functions of artifacts, given that the intended function of an artifact is generally thought to constitute core conceptual information…

The influence of three mechanisms of working memory (phonological short-term memory (PSTM capacity), attentional resource control/allocation, and processing speed) on children's complex (and simple) sentence comprehension was investigated. Fifty two children (6-12 years) completed a nonword repetition task (indexing PSTM), concurrent verbal…

In comprehending stories, adults create mental models from which they follow the actions of the characters from the characters' different mental vantage points. Using a novel methodology, this study is the first to examine when children attain the narrative ability to track the mental perspective of characters. That is, when do children follow…

Three experiments investigated (1) whether developmental differences in the information integration rule apply to ulterior motive information; (2) whether such developmental differences are limited to situations involving parental reward; and (3) how related age differences among children can best be explained. (RH)

Four studies involving 160 children of 4-11 years and 14 adults focused on the development of beliefs about selective attention. Children's beliefs about attention appeared to change greatly during the age range studied. Predictions of successful comprehension of unattended stories declined sharply between ages 4 and 6. (RJC)

Infants of 14 months of age demonstrated significantly improved understanding of containment as a result of a training intervention in which they played with cans and tubes in their homes for a month. After training, their test scores were similar to those of untrained 20-month-old children. (RH)

The purpose of this study was to measure the development of forethought in children as a function of age, thereby documenting a normal use of this facility. It was hypothesized that forethought would develop on a continuum increasing with age, with no significant differences due to sex of the child. To test this hypothesis, items were pooled which…

The ability of three- and four-year-old children to reason about the components of event sequences involving simple transformations was tested in two experiments. In Experiment I children saw picture "stories" of the form object, instrument, and transformed object, with one item deleted. In Experiment II only the instrument item was…
