Uses multidimensional scaling procedures to investigate developmental changes in the ability of 80 male subjects (aged seven, nine, 12, or adult) to process previously unfamiliar faces. Suggests that improvement in face recognition ability at age 10 results from an increased ability to consider more features simultaneously. (Author/BE)

Observations suggest that 12-month-old children show little evidence of possession rules, while 18- and 24-month-olds are still coming to differentiate purely personal possession rules from shared possession rules that take into account the other child's status or rights as a possessor. Children 12 months old exhibited the highest frequency of…

Two naming tasks were simultaneously presented to either one visual field/hemisphere combination or were divided between visual fields/hemispheres. Hypotheses that bilateral presentation would improve performance by insulating conflicting tasks from mutual interference and that there would be a developmental shift in the bilateral advantage was…

Assesses five- and 10-year-old children's understanding of second-order belief structures in acted stories in which two characters were independently informed about an object's unexpected transfer to a new location. Results show unexpected early competence around age six or seven under optimal conditions when inference of second-order beliefs is…

An error-detection paradigm was used to examine the ability of young and old adults of varying educational levels to comprehend texts. Results indicated that young and old adults were equally able to detect textual inconsistencies; however, better educated adults detected more inconsistencies than less educated adults. (Author/RH)

Despite assertions to the contrary, preschool children are capable of understanding cinematic events conveyed through camera techniques and film editing. This ability nevertheless substantially increases with age among children from four- to seven-years-old. (Author/RH)

Recent work suggests that the apparent shift from thematic to taxonomic concept organization reflects changes in children's preference for these forms of organization, rather than their capacity. A study was made to assess toddlers' knowledge of the different possible relations for the same concept and to extend the triad method to children under…

A 2-part investigation was conducted to examine the ways children resolve the inherent ambiguity of spatial descriptions in terms of cues indicated by the three constituents of spatial propositions: predicate, referent, and relatum. In the first study, it was hypothesized that certain objects, structural markers, and definite articles accompanying…

While six- and nine-year-olds were as good as adults in distinguishing what they did from what they saw someone else do, children had particular trouble across a range of actions in distinguishing actual from imagined doing. All subjects recalled actions according to performer; organization by person categories reduced clustering based on action…

Children's ability to produce integrated sequences of discrete behaviors was examined as a function of age and task demands for several behavioral domains. Results are discussed in terms of possible age-related constraints on combinatorial skills that operate at a general, cross-domain level during toddlerhood. (RH)

Investigates which formal principles govern subjective probability, and whether the validity of these principles depends on age. Results indicate that these principles are valid as principles of subjective probability for all age groups. (RWB)

Young and older nursery school children were taken to three locations in their school and asked to point to five targets on the school grounds. Older children were more accurate than younger children, but children's spatial representations were relatively nonintegrated at both age levels. Consistent sex differences in favor of males were found.…

Examines the ability of six- and eight-year-old children to hide and recover 20 marbles in a large room containing 100 possible sites. Shows that children tend to concentrate activities in sections of the room and are sensitive to clusters of proximal sites. (HOD)

Analyzes sex-related differences between mental rotation rate and spatial ability among adults, 14-year-olds, and 9.5-year-olds to determine the extent to which rotation rate is a correlate of various abilities. (HOD)

First- and fifth-grade children were presented a hypothetical case in which a child, who circumstantial evidence suggests might have committed a "crime," is punished by a parent. Subjects were asked to indicate whether or not they believed the punishment to be fair and the child guilty. (Author/RH)
