In this paper we examine two long-standing assumptions of the information processing perspective of perceptual-motor development, namely that: (1) the amount of noise in children's sensori-motor system decreases with increases in age up to adulthood; and (2) this age-related reduction in noise level leads to associated improvements in the accuracy…

It is proposed that knowledge of motor commands is used to distinguish self-generated sensation from externally generated sensation. In this paper, we show that the sense of self-agency, that is the sense that I am the one who is generating an action, largely depends on the degree of discrepancy resulting from comparison between the predicted and…

Restricted and repetitive behaviors (RRBs) on the Autism Diagnostic Interview- Revised (ADI-R: Lord, Rutter, & Le Couteur (1994) were examined in 165 children with Autism Spectrum Disorders (ASD), 49 children with non-spectrum developmental disorders (DD), and 65 children with typical development (TD) at approximately 2 years of age. A factor…

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory…

Studies the extent to which psychometric and Piagetian scales correlate during infancy and also explores the nomological networks of these scales and the degree to which their networks are similar. (LLK)

The results of this study fail to provide a basis for concluding that the ability to perform a simple coincidence anticipation task with the right foot is facilitated by subsequent practice with the left foot. (MM)

Four experiments investigated the role of geometric path type in infants' ability to make spatial inferences about the location of a hidden object after the infants had been moved. In all but the fourth experiment, infants were able to retrieve the objects unless objects were located behind the infants. (SKC)

In children with myelomeningocele, paralysis and loss of sensation occur below the level of the spinal cord lesion. Since upper extremity functioning does not seem to be impaired in these cases, this study describes hand function and relationships between hand function and motor, sensory, and intellectual levels.

Effects of test order within Ayres Southern California test battery were studied in 5-, 6- and 7-year old children referred for perceptual motor evaluation.

Guidelines are discussed regarding the development and implementation of perceptual motor programs for autistic children. Among suggestions offered are to choose reasonable objectives, use movement to develop child-therapist rapport, emphasize the elements of transfer, use the kinesthetic approach and make use of teachable moments.

For 89 White children 6 to 11 years old and of upper middle class, scores on Piagetian tasks of conservation of length and volume were related to age but field independence was correlated significantly to these scores. (Author)
