Findings indicated that (1) stable preference measures could be obtained, (2) high preference objects resulted in higher motivation to perform and hence higher levels on each scale, (3) performance of this population is not stable, and (4) ordinality was violated in nearly 20 percent of the administrations of the scales.

Evaluated 9-, 14-, and 19-month olds' strategies as they grasped and used spoons presented with the handle alternately oriented to left or right. Found that younger children reached with their preferred hand, disregarding the item's orientation. Older children anticipated the problem, alternated the hand used, and achieved an efficient radial grip…

Examined infants' ability to retrieve an object from atop a slightly larger object. Found that even 5-month-olds could retrieve objects close in size and fully contiguous with their bases when demands on reaching skill were reduced. Proposed that when they fail this task, it is because they lack the skill to reach the top object without…

Describes writing as a complex process requiring cooperation of cognitive, perceptual, and motor activities. Examines current trends in handwriting instruction and Montessori's approach to handwriting instruction. Describes the indirect preparation through Montessori materials and a direct teaching approach involving a simplification of the…

Two experiments investigated sensory/motor-based functional knowledge of man-made objects: manipulation features associated with the actual usage of objects. In Experiment 1, a series of prime-target pairs was presented auditorily, and participants were asked to make a lexical decision on the target word. Participants made a significantly faster…

Environmental familiarization is a learning phenomenon embedded within most tasks used to study learning and motivation. Given its prevalence there is surprisingly little systematic behavioral research on factors affecting familiarization. The six experiments reported in the present report used rats' tendency to interact more with a novel object…

Three French-speaking agrammatic aphasics and three French-speaking Conduction aphasics were tested for comprehension of Active, Passive, Cleft-Subject, Cleft-Object, and Cleft-Object sentences with Stylistic Inversion using an object manipulation test. The agrammatic patients consistently reversed thematic roles in the latter sentence type, and…

D. M. Shaffer and M. K. McBeath (see record 2002-02027-006) plotted the optical trajectories of uncatchable fly balls and concluded that linear optical trajectory is the informational basis of the actions taken to catch these balls. P. McLeod, N. Reed, and Z. Dienes (see record 2002-11140-016) replotted these trajectories in terms of changes in…

Tool use consists of at least two coupled phases of activities, involving multi-step problem solving. It therefore provides an interesting window on the development of planning in goal-directed behavior. This study investigated 2-year-olds' and 3-year-olds' hand use in picking up and subsequently using a tool for displacing a target-object towards…

In this study, a desktop virtual reality earth motion system (DVREMS) is designed and developed to be applied in the classroom. The system is implemented to assist elementary school students to clarify earth motion concepts using virtual reality principles. A study was conducted to observe the influences of the proposed system in learning.…

To determine the effects of pencil shape and size on motor accuracy and pencil posture of eight-year-old children, a study randomly assigned 54 third grade school children to one of three experimental conditions: (1) using a standard 2B pencil, (2) using a 1.5 cm thick 2B pencil, and (3) using the standard 2B pencil with the attachment of an…

This study investigated the effects of novelty on young children's exploration of commonplace, 3-dimensional objects. The exploration of novel and familiar objects was compared and the pattern of the exploration of the novel object over a period of time was examined in order to test two hypotheses: (1) that novel objects elicit more exploration…

THE PURPOSE OF THIS STUDY WAS TO FIND OUT WHETHER SOCIAL CLASS DIFFERENCES IN INTELLECTUAL DEVELOPMENT ARE PRESENT IF (1) CHILDREN FROM SOCIALLY DISORGANIZED SLUM FAMILIES ARE COMPARED WITH CHILDREN FROM STABLE, LOW INCOME AND MIDDLE INCOME FAMILIES, (2) THE PIAGET OBJECT SCALE, A NEW MEASURE OF COGNITIVE DEVELOPMENT BASED ON PIAGET'S SENSORIMOTOR…

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)
