Reports an error in "Does Barbie make girls want to be thin? The effect of experimental exposure to images of dolls on the body image of 5- to 8-year-old girls" by Helga Dittmar, Emma Halliwell and Suzanne Ive ("Developmental Psychology," 2006 Mar, Vol 42[2], 283-292). A substantive error occurs in the Body shape dissatisfaction section on page…

The importance of awareness of the pictorial surface and point of observation was investigated in children and adults. The effect of station point was found to interact with pictorial surface and age, thus suggesting the development of a mechanism of compensation for the perspective distortion of oblique view. (JMB)

Tested infants of six to eight months and children of 5.5 years for their discrimination of silent intervals between elements of auditory patterns. Both groups could detect increments, and the context of a temporal increment influenced its detectability. (SKC)

Tested the hypothesis that some attempts to reduce the performance demands of concrete Piagetian operational tasks may have allowed children to solve those tasks with preoperational functions. Administered two previously used versions of the transitivity task for length and weight to 120 children six- to nine-years-old. The second version was…

Investigated friendship patterns among four-year-old mildly developmentally delayed and three- and four-year-old nonhandicapped children participating in a series of mainstreamed playgroups. Most children preferred a specific peer, but only a few mildly delayed children and three-year-olds were able to establish reciprocal friendships. (SKC)

Two conflicting developmental accounts of how mental states are used in evaluating actors were tested by varying actors' intentionality, foreknowledge of outcome, and the values of motive and outcome. Findings suggested that children use intentionality before knowledge in judgments of action sequences and that actor's foreknowledge of an outcome…

Described is the development of a method for identifying and classifying differing attachment organizations at six years of age. The system is based on an analysis of children's responses to reunion with parents following a one-hour separation. Sixth year attachment classifications to mother were found to be highly predictable from infancy…

The Junior Self-Monitoring Scale, a new measure, was developed and related to individual differences in children's tendencies to engage in social comparison when making decisions. This study demonstrated that children scoring high in self-monitoring were more likely than low self-monitoring children to attend to the decisions of other children.…

Following nutritional recovery from severe protein-calorie deficiency, 20 young children evidenced a retarded level of categorization behavior compared to a control group of 19 adequately nourished children from similar socioeconomic background. (NH)

Examined the existence of preschoolers' assumption of one-proper-name-to-one-individual in their word learning. Subjects were 90 4-year olds. Found that children were likely to interpret a word as a proper name if it was applied to one instead of two objects. However, children overrode this default assumption if sufficient contextual information…

In three experiments, 3-, 4-, and 5-year olds and adults identified words from a list presented by a single talker or multiple talkers. Subjects were less accurate identifying or slower repeating words spoken by multiple speakers than by a single speaker. Processing of multiple speakers' words became easier with age. Children matched their…

Used story grammar to analyze pretend play productions of 46 children of 4-8 years. Results showed structural parallels between pretend play and stories for 76 percent of subjects. Older subjects' play was episodic and younger subjects' was preepisodic. (RJC)

Examined developmental change in the duration of memory for tone pitch in children and adults. In experiment 1, performance on a two-tone comparison task deteriorated across the intertone interval more quickly in younger than in older subjects. Experiment 2 demonstrated that the developmental difference in pitch memory persistence is unlikely to…

Examined association of individual differences in physical maturation with information-processing speed among 9- and 10-year olds. Found that early maturers were faster than late matureres, although this maturity effect was primarily the result of a significant effect for boys. The early maturers' faster processing times may be specific to boys or…

Surface and relational similarity were examined in two experiments involving isomorphic and nonisomorphic analogical transfer, using direct-mapping and cross-mapping conditions. In the first experiment, third and sixth graders exhibited mapping based on relational similarity more frequently than did kindergartners; in the second, most four- to…
