Central mechanisms of motor skill learning.

Recent studies have shown that frontoparietal cortices and interconnecting regions in the basal ganglia and the cerebellum are related to motor skill learning. We propose that motor skill learning occurs independently and in different coordinates in two ...

Ideomotor compatibility in the psychological refractory period effect: 29 years of oversimplification.

Four experiments examined whether the psychological refractory period (PRP) effect can be eliminated with ideomotor compatible (IM) but not stimulus-response compatible (SR) tasks, as reported by A. G. Greenwald and H. G. Shulman (1973). Their tasks were ...

Long-term consequences of switching handedness: a positron emission tomography study on handwriting in "converted" left-handers.

Until some decades ago, left-handed children who attended German schools were forced to learn to write with their right hand. To explore the long-term consequences of switching handedness, we studied the functional neuroanatomy of handwriting in 11 adult ...

Motor-induced brain activation in cortical, subcortical and cerebellar regions in schizophrenic inpatients. A whole brain fMRI fingertapping study.

Motor symptoms including neurological soft signs have been found to be more prevalent in schizophrenic patients. In addition, catatonic symptoms and neuroleptic treatment as well may influence cortical and subcortical motor organization in schizophrenia. ...

Visuomotor rotations of varying size and direction compete for a single internal model in motor working memory.

When participants adapt to equal and opposite visuomotor rotations in close temporal proximity, memory of the 1st is not consolidated. The authors investigated whether this retrograde interference depends on the use of equal and opposite rotations. On ...

Health status of school-aged children with cerebral palsy: information from a population-based sample.

In this study parents systematic accounts of the health status of 408 school-aged children with cerebral palsy (CP) are reported (221 males, 187 females; mean age 8 years 5 months, SD 1 year 11 months; range 5 to 13 years), as are relations between ...

Validity of the Test of Infant Motor Performance for prediction of 6-, 9- and 12-month scores on the Alberta Infant Motor Scale.

The Test of Infant Motor Performance (TIMP) is a test of functional movement in infants from 32 weeks post-conceptional age to 4 months postterm. The purpose of this study was to assess in 96 infants (44 females, 52 males) with varying risk, the relation ...

Feeding behaviors and other motor development in healthy children (2-24 months).

OBJECTIVES: To monitor infants gross, fine and oral motor development patterns related to feeding. DESIGN: An incomplete block design was used with 57 to 60 (sample = 98) mothers interviewed when their children were 2, 3, 4, 6, 8, 10, 12, 16 and 24 ...

Problems in developing functional handwriting.

The development of handwriting quality and speed of 407 primary school children was followed from Grade 1 to Grade 5 in a longitudinal experiment. Performance was analyzed to enquire into the extent and bases for handwriting dysfunction. 27% of the ...
