The extent to which free play versus sequenced questioning conditions facilitates preschoolers' associative fluency was investigated in this study. Twenty-four children (12 boys and 12 girls, with a mean age of 50.7 months) were randomly assigned to one of three conditions: free play, sequenced questioning, and control. In the sequenced…

The purpose of this study was to determine whether motor activity, previously assumed necessary to induce visual imagery in young children's associative learning, actually has to be executed in order for children to generate images. The results of an experiment with 96 kindergartners clearly suggest not: in conditions where subjects simply planned…

The distribution of intermanual discrepancies on three motor tests (Grooved Pegboard, Finger Tapping and Dynamometer) were examined in normal and unilateral brain lesion samples. Considerable variability in the intermanual discrepancies was observed in all three samples. Therefore, the consistency of discrepancies across tasks was examined. The…

Research on object exploration by infants addresses milestones in the process by normally developing infants, including spontaneous manipulation strategies. Implications for developmentalists working with high-risk preterm infants are noted, including the need for direct assistance in manipulation and for selection of materials. (CL)

Describes a two-year college-level program in air traffic control. (GR)

The effectiveness of sound as a reinforcer of manipulative responses was studied with 50 infants four to 12 months old. Noisy toys were manipulated significantly more frequently than quiet ones by infants from six to 10 months old. (Author/SEW)

Sighted subjects assembled puzzles under separate conditions of visual-haptic perception and used vision and touch simultaneously to illustrate visual-type involvement and links in haptic encoding processes. A cognitive component in perceptions was found. When visual input was inadequate or independent of haptic perception, tactual information was…

Details are presented regarding the essential elements of an effective early childhood physical education curriculum. Components include movement awareness, fundamental locomotor skills, fundamental nonlocomotor skills, fundamental manipulative skills, and health-related fitness. (CB)

Observed drawing by toddlers and preschoolers using primary and standard markers, pencils, and crayons to determine the influence of implement diameter on children's drawing products, performances, and preferences. The relationship between drawing and early home manipulative experience was also investigated. Confirmed findings of previous studies…

The conceptual categories that children have developed in their second year were studied in five experiments using object manipulation tasks. Subjects included 152 children from 18 to 31 months of age. These very young children had formed global conceptions of many domains of objects. (SLD)

Two experiments used object-manipulation tasks to examine whether one- to two-year-olds form superordinate-like categories by attending to object parts. Findings indicated that 14- and 18-month-olds behaved systematically toward categories with different, but not matching, parts. Without part differences, none formed superordinate categories.…

Discusses the development of the human hand from birth to age three as it contributes to the formation of human personality. Considers how parallels in eye, hand, brain, and motor skill development portray the evolving complexity and adaptation of the human grasp and illustrate Montessori theories about the relationship between physical experience…

The purpose of this study was to examine the effects of an animated agent that provides instructional scaffolding strategies via a story mnemonic or cuing question with feedback versus instructional scaffolding strategies alone on student achievement of different educational objectives in multimedia learning. Specifically, the study investigated…

Three experiments attempted to clarify the effect of altering the spatial presentation of irrelevant auditory information. Previous research using serial recall tasks demonstrated a left-ear disadvantage for the presentation of irrelevant sounds (Hadlington, Bridges, & Darby, 2004). Experiments 1 and 2 examined the effects of manipulating the…

Conjunction errors occur when participants incorrectly identify as "old" novel test stimuli created by recombining parts of two study stimuli (parent items). Prior studies have reported that the conjunction error rate is higher when parent items are studied together than when they are studied apart (a parent proximity effect). In several…
