Two experiments with monolingual German-speaking 2.5- to 4.5-year-olds showed a consistent developmental gap between children's memory/inference of what someone wanted and what someone wrongly said or thought. Correct answers emerged with mastery of the false-belief task. It was concluded that the observed gap constrains de Villiers's linguistic…

Investigated children's causal-explanatory conceptions of the workings of a labeling strategy. The 72 children of four-six years showed two types of conceptions, both of which increased with age. (RJC)

Two studies examined the positivity bias in children of different ages. Findings indicated that children from grade two and up selected the correct cause(s) when the effect covaried with only one cause, but only at a later age when covariation with two causes was presented. Ability estimations and expectation of success were more positive in…

Maintains that there are core-specific and non-core-specific domains of knowledge, but that only the core-specific domains benefit from innate skeletal structures. Asserts that core skeletal domains are universally shared, even though their particular foci may vary. Emphasizes that individuals vary in terms of the noncore domains they acquire.…

Two studies compared how preschoolers through fifth graders and adults reasoned about psychogenic bodily reactions such as stress-induced headaches. Results supported a developmental path: younger children view psychogenic bodily responses as wholly physical, but with age, view them as both physical and psychological. (Author/KB)

The theory-of-mind abilities of twins, children with nontwin siblings, and only children were compared to investigate further the link between number and type of siblings and theory-of-mind abilities. Three- to 5-year-old children with nontwin siblings outperformed both only children and twins with no other siblings, twins who also had other…

Prior research demonstrates that understanding theory of mind (ToM) is seriously and similarly delayed in late-signing deaf children and children with autism. Are these children simply delayed in timing relative to typical children, or do they demonstrate different patterns of development? The current research addressed this question by testing…

A sample of 48 preschoolers were asked to ride a tricycle appropriately following commands presented at 3-second intervals. Half of the children were also asked to repeat the commands aloud. Results are presented for frequency of inappropriate motor activity and reaction times. (Author/JMB)

This study assessed the predictive utility of a classification-based model versus a representational memory-based model to account for the effects of verbal training on the acquired equivalence and distinctiveness paradigms. (Author/JMB)

The relation between past history of outcomes and achievement expectancies was examined for 72 elementary school students. (JMB)

The hypothesis that, when trying to decide whether the person, stimulus, or circumstance is the cause of an event, individuals increasingly select schema-consistent information with increasing age was tested in 106 Turkish 9-, 12-, and 17-year-old subjects. (Author/RH)

Contrasts effects of three modes of mother/child interaction on children's subsequent compliance with maternal directives. Subjects were 39 children from lower-middle-class families, ranging in age from approximately three to four-and-a-half. Responsive play and noninteractive conditions produced higher levels of compliance than the untrained free…

Investigates logical and perceptual determinants of social-cognitive development by examining children's use of consensus information for causal attribution. Results verify the importance of perceptual processes, demonstrating that children can use consensus for person attribution earlier in development than they can for stimulus attribution.…

Examines the role of affect in children's attribution of intentionality and dispensation of punishment. Subjects were 12 boys and 12 girls at each of three grade levels: kindergarten and first and second grades. (CM)

Tests Piaget's interpretation of long-term memory improvement among 82 five- and six-year-old children. Concludes that there is little evidence for long-term memory improvement or for Piaget's theory of memory. (Author/RH)
