Nervous systems extract sensory information from the environment to guide behavior. The underlying neural mechanisms have been studied extensively, in part by identifying neurons with responses linked deterministically to sensory and motor events. Higher nervous systems are also capable of widespread cognitive abilities, includin interpretation, decision-making, valuation, intention, language, ...

The aim of the study was to analyze the relations of cognitive processors and conative regulators with specific motor abilities of elite boxers. Three sets of variables including 3 cognitive and 6 conative variables as predictors, and 6 specific motor (boxing) variables as criteria were used in a sample of 92 boxers. A series of regression analyses between the set of cognitive variables and par...

BACKGROUND Previous studies suggested that children diagnosed with fragile X syndrome (FXS) often meet criteria for autism or PDD. This study describes the fine motor abilities of children diagnosed with FXS with and without autism spectrum disorder, and compares the motor scores of those groups controlling for cognitive level. METHOD Forty-eight children, ages 12-76 months (SD = 16) diagnose...

Anticipatory motor planning abilities mature as children grow older, develop throughout childhood and are likely to be stable till the late sixties. In the seventh decade of life, motor planning performance dramatically declines, with anticipatory motor planning abilities falling to levels of those exhibited by children. At present, the processes enabling successful anticipatory motor planning ...

Molecular motors are quintessential bio-machines found throughout phylogeny. A new application of in vitro assays highlights an unexpected dual functionality for the motor domain of the microtubule-based kinesin-14 type motor protein from budding yeast.

Previous studies on fine and gross motor skills of children with childhood apraxia speech (CAS) have reported inconclusive results. In this study, we investigate the abilities CAS by focusing three distinct factors: control during movement, skills/handwriting, general coordination. Participants included 25 20 age-matched typically developing (TD) between ages 5 7 years. Motor were evaluated usi...

The heritability of abilities increases substantially over development, and much of heritable variation in abilities is shared with other abilities. No study, however, has formally tested the extent to which developmental increases in heritability occur on shared versus unique variation in child abilities. A transactional perspective predicts that the relative proportion of shared to total gene...
