A total of 12 three, four, five, seven, and nine year olds and 12 adult control subjects were asked 20 questions about two exemplars of each of 16 categories of animate beings and inanimate objects. Children's responses indicated that animism is not a pervasive phenomenon and does not appear to be the most primitive mode of conceptualization.…

When not socially engaged, children showed a significantly greater percentage of reoriented attention during vocalizing than nonvocalizing periods. Findings confirm the existence of an attention/vocalization relation and are consonant with Greenfield's predictions about the nature of this relation. The relation held equally for prelinguistic and…

Displays that by themselves always elicited chance judgment of number were shown to three- to four-year-olds and six- to seven-year-olds. The first display was transformed into the second, and so on. Results indicated that three- to four-year-olds do not understand conservation of number because judgements of successive displays were independent…

Examines the development of integration and comprehension monitoring in four-, five- and eight-year-olds. Children listened to stories containing a nonspecific premise, two sentences that converged on an interpretation of the premise, and an anomalous sentence. Results were interpreted as evidence for three developmental levels of integrative…

Assesses ability of subjects aged 3 to 6 and 10 to 12 to solve a problem by analogy. Subjects had to discover ways to transfer balls to a bowl; stories read first to some subjects included an analogous problem and its solution. Older children's use of analogies was similar to that of adults; younger children exhibited different limitations.…

Results support Kohlberg's speculation that orientational preference rather than level of stage structure may be the primary area in which sex differences in moral judgment are manifested. It is concluded that ascriptions of greater adequacy or maturity to the moral thought of one or the other sex are appropriate. (RH)

Assesses three sets of Piagetian exclusion operations (of varying the independent variables, of holding the independent variable constant, and tautology) and of levels of thought (concrete through formal) in 33 fifth graders, 27 sixth graders, and 31 seventh graders. (HOD)

Finds that, between five and seven years of age, the majority of healthy children in modern urban-industrial societies achieve an understanding of the irreversibility, nonfunctionality, and universality of death. Suggests reasons for ambiguous findings concerning the relationship between the acquisition of the concept of death and developmental…

Evaluates some possible reasons for the occurrence and eventual correction of children's naming errors in an experiment in which two-, four-, and six-year-olds learned two artificial object names in succession. (HOD)

Compares two types of semantic development (the acquisition of disappearance words and success-failure words) to performance on two types of cognitive tasks (object-permanence and means-ends tasks) among infants. (HOD)

Involving second, fourth, sixth, eighth, and tenth graders and undergraduates, three experiments evaluated the prediction that representations of knowledge of the weeks and months of the year develop from a verbal-list stage to a stage at which image representations are present. Results are interpreted as supporting the two-stage model and appear…

Asks adults and 6-, 9- and, 13 year olds' questions about tape-recorded stories in order to investigate their ability to recognize sincere, deceptive, and sarcastic remarks. Results indicate that the youngest children interpret all remarks as sincere; 9 and 13 year olds can appreciate deliberate falsehood, but only adults identify sarcasm.…

Reanalyzes data from a study in which 42 fifth graders received training in map-drawing skills. Explores the relationship between the mixture of reasoning levels and developmental change, and compares findings with those of an earlier study of social reasoning. (CB)

Tests two hypotheses concerning developmental change in the speed of cognitive processes: (1) age differences in processing time reflect changes that are specific to particular tasks, and (2) age differences in processing speed do not reflect task-specific change but are due instead to more general developmental change. (HOD)

Describes two experiments that examined children's understanding of the distinction between real and apparent emotion. Discusses the findings in relation to research concerning children's concept of mind, their grasp of the appearance-reality distinction; their ability to produce complex, embedded justifications; and their ideas about emotion.…
