PRACTICE, with feedback, is a fundamental variable that influences the aquisition of motor skills1: with it, everyone improves, but some improve more than others. This simple fact has led to frequent debate over the relative importance of genetic and environmental influences on motor learning. In principle these factors could influence subjects' initial level of proficiency, their rate of improvement or their final level of attainment. The problem has been investigated using the rotary pursuit… 

Heritability of motor control and motor learning

The present findings suggest that heredity accounts for a major part of existing differences in motor control and motor learning, but uncertainty remains which gene polymorphisms may be responsible.

Nature, nurture, and expertise

Heritability in neuromuscular coordination: implications for motor control strategies.

In this study, heredity accounted for most of the existing differences in neuromuscular coordination in fast movements and implies that movement strategies, which are organized in the CNS and control fast movements, are also strongly genetically dependent.

Genetic associations with learning over 100 days of practice

Cognitive performance is both heritable and sensitive to environmental inputs and sustained practice over time. However, it is currently unclear how genetic effects on cognitive performance change

Heritability of proprioceptive senses.

This study is the first to report that proprioception, expressed as movement sense, position sense, and force sense, is substantially heritable, and it is conceivable that this may have implications for motor learning and control, neural development, and neurorehabilitation.

Perceptual-motor styles

Some potential applications of the concept of perceptual-motor style to different areas of neuroscience, both in the healthy and the diseased are covered, even at the expense of running the risk of encompassing loosely related studies.

Genetic basis in motor skill and hand preference for tool use in chimpanzees (Pan troglodytes)

It is found that motor skill decreased with age and that males were more commonly left-handed than females, which suggest that though non-genetic factors do influence tool use performance and handedness in chimpanzees, genetic factors also play a significant role, as has been reported in humans.

Genes, Environment and Sport Performance

It is argued that, due to inherent human degeneracy, there are many different trajectories to achieving elite Athletic Performance, and the concept of degeneracy provides a basis for understanding why each of the major interacting constraints might act in a compensatory manner on the acquisition of elite athletic performance.



Genetic and extragenetic variance in motor performance.

It is disclosed that a greater proportion of genetic factors, as opposed to nongenetic factors, appears to account for existing individual differences in motor performance among individuals subject to similar environmental conditions.

Emergenesis. Genetic traits that may not run in families.

Personal idiosyncrasies that have been found to be surprisingly concordant among MZ twins separated in infancy and reared apart may be emergenic traits, which reemphasize the importance of the role played in human affairs by genetic variation.

Adjustment of twin data for the effects of age and sex

It is concluded that, even with moderately sized samples, the effects of age and sex can best be adjusted for through a twin-based approach.

Coefficient alpha and the internal structure of tests

AbstractA general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of

Sources of human psychological differences: the Minnesota Study of Twins Reared Apart.

Evidence for the strong heritability of most psychological traits, sensibly construed, does not detract from the value or importance of parenting, education, and other propaedeutic interventions.
