Studied the emotional attributions which 60 children aged four-eight gave to a story figure who violated a moral rule. Results suggested a clear change from outcome-oriented toward morally oriented attributions to a moral wrongdoer between the different age groups. (RJC)

Examines personal relevance in relation to the ability of 48 5- to 10-year-old children to describe others in terms of psychological characteristics. Results suggest that verbal inferencing skills of young children have been underestimated and that they may be more oriented toward affective goals than older children when anticipating interaction…

Findings of three experiments indicated that preschool children have a more substantial knowledge of contagion and contamination than has been estimated previously. Results are discussed in terms of children's ability to understand causal relations. (RH)

Interview responses of 72 fifth-, eighth-, and eleventh-graders revealed developmental changes in the scope and nature of perceived peer influence and in the extent to which peer group reactions have an impact on self-evaluations. Developmental changes in the apparent reference-group functions of peer groups for adolescent identity formation are…

When three-, four-, and five-year-old children learned about the contents of a drawer in three different ways and were asked, immediately and after a brief delay, how they knew about the contents of the drawer, three-year-olds had difficulty identifying the sources of their knowledge, while five-year-olds did not. Delay increased difficulty for…

Three-, four-, five-, and 24-year-olds were exposed to continuum of new objects: category boundaries became less fuzzy with age; verbal justifications of category decisions were idiosyncratic or uninterpretable in youngest children, but by five years children referred to specific visual features; and fuzzy categories became less sensitive with age…

Assessing Markman's hypothesis that the organizational principles underlying collection concepts facilitate children's performance on cognitive tasks requiring part-whole comparisons, three experiments indicated that the facilitative effect of collection labels appears to be specific to the class-inclusion task. Results suggest that Markman's…

The main finding that three- and four-year-old children can make inferences relating numerosity and one-to-one correspondence information implicate more mathematical knowledge than Piaget attributed to young children. Their knowledge does not appear to be as closely tied to counting and other action schemas as other accounts of early numerical…

The influence of cultural practices on the cognitive development of largely unschooled children was investigated among 23 candy sellers and matched non-vendors between 10- and 12-years-old who resided in northeast Brazil. Findings are interpreted as supporting a model of cognitive development in which children construct novel understandings while…

Experiments revealed that children seemed able to integrate multiple sources of information but were more dependent on clue support and generally less likely to infer reason than adults. Children were more likely than adults to reject premise as an explanation of outcome. Only fourth-graders and adults modified inferences in response to resolution…

Compares the cognitive representation of number of 24 American, 25 Chinese, 24 Japanese, and 40 Korean first-graders, and 20 Korean kindergartners. Chinese, Japanese, and Korean children preferred to use a construction of tens and ones to show numbers, whereas English-speaking children preferred to use a collection of units. (RJC)

Evaluates the effects of presenting verbal models following the initiations or expressions of interest of 16 children aged 28 to 34 months on both production and comprehension abilities measures. Results suggest that the timing of exposure to language models plays a critical role in language acquisition. (RJC)

Studied the development of speech act comprehension in 36 retarded and 36 nonretarded children at the developmental ages of five, seven, and nine years. Retarded and nonretarded individuals followed the answer obviousness rule and used the contextual and linguistic clues available to respond to yes-no interrogative sentences. (RJC)

Investigates the evidence that the imperfect performance in forward search of 36 children aged four and five years resulted from unstable execution of the correct component processes. Evidence suggests that five-year-olds engaged in forward search, but four-year-olds used only a rudimentary form of forward search. (RJC)

Examined two- to four-year-olds' and adults' internalized representations of the sizes of buttons, plates, and shoes in five experiments. Results suggested that three- and four-year-olds had accurate knowledge of the typical sizes of buttons and plates. Two-year-olds demonstrated accurate internal representations of the sizes of shoes.
