The ability of two and three-year-old children to comprehend the prepositions in, on, and under was tested. Results suggest that the young child's comprehension of locative instructions involves an interaction between aspects of the instruction's word meanings, word order, and the child's understanding of the context.

An interaction analysis observation instrument, with categories found in the definition of "executive competence" by Wenar and related to R. White's effectance motivation, was used to observe 37 toddlers with their mothers. (SB)

Two experiments using college students established links between desired knowledge about objects and hand movements during haptic object exploration. Subjects were either blindfolded or had their hands restrained, while performing matching tasks. Hand movements were studied during performance of exploratory procedures. (GDC)

Recent work on the development of the perceptual information-seeking function of the hand in relation to its motor-executive function is reviewed. (PCB)

Tested infants in their second year with a box task to determine whether they would show a hand preference in solutions involving complete differentiation of roles for the two hands. (HOD)

Compares the manipulative exploration of objects of 30 nine-month-old preterm infants with that of 20 nine-month-old full-term infants. Although no difference between the preterms and the full terms was noted, a high-risk preterm subgroup manipulated objects less. A relationship was found between manipulative exploration at nine months and later…

Investigates the exploratory behavior of young children as it relates to individual differences in curiosity, the novelty of the objects explored, and the interactive style employed by an adult experimenter. (Author/MP)

Use of manipulatives is neither a sufficient nor a necessary condition for meaningful learning. Provides some incidents in support of the argument. Lists 14 references. (YP)

Studied the early development of exploratory behavior in 99 infants of 2-5 months. Results show that there are significant changes in spontaneous multimodal exploration of a novel object between 2 and 5 months. (RJC)

Comparison of 40 children with Down's syndrome and typically developing children (matched for mental age) found that the children with Down's syndrome appeared less engaged in a task, as indicated by shorter sequences of goal directed behavior and higher rates of toy rejection. They also displayed less causality pleasure with object exploration…

Toddlers with Down's syndrome (n=42) were presented with situations in which the primary focus alternated between an object stimulus and a social stimulus. The experimental subjects monitored their environment in the same manner as did the 25 control subjects (matched for mental age) during object mastery but had a more focused attention style…

The development of object play was longitudinally examined in 40 children ages 11 to 27 months. The types of object play observed in nondisabled children were observed in children with disabilities at comparable developmental ages. Duration and frequency of active involvement with objects were greater for nondisabled children than for children…

Human toddlers demonstrate striking failures when searching for hidden objects that interact with other objects, yet successfully locate hidden objects that do not undergo mechanical interactions. This pattern hints at a developmental dissociation between contact-mechanical and spatiotemporal knowledge. Recent studies suggest that adult non-human…

Although a considerable amount is known about the development of object manipulation during the 1st year, less is known about how infants manually explore surfaces and relate objects to surfaces. To address these issues, 60 infants (20 each at 6, 8, and 10 months of age) were presented hard and soft objects on tabletop surfaces, which varied in…

One of five McDonald's Action Packs, this teacher's guide and activity sheets describe an early childhood-level program that introduces basic movement and guides students and teachers into the process of learning through moving. Basic movement skills necessary for sports and games, gymnastics, and dance are developed through eight themes, each…
