Left preference for sport tasks does not necessarily indicate left-handedness: sport-specific lateral preferences, relationship with handedness and implications for laterality research in behavioural sciences. [PDF]
In the elite domain of interactive sports, athletes who demonstrate a left preference (e.g., holding a weapon with the left hand in fencing or boxing in a 'southpaw' stance) seem overrepresented. Such excess indicates a performance advantage and was also

Handedness in twins: meta-analyses
Background In the general population, 10.6% of people favor their left hand over the right for motor tasks. Previous research suggests higher prevalence of atypical (left-, mixed-, or non-right-) handedness in (i) twins compared to singletons, and in (ii)

Aetiological factors in left-handedness [PDF]
Lateralisation associates the extremities and senses of one side of the body, which are connected by afferent and efferent pathways, with the primary motor and sensory areas of the hemisphere on the opposite side.

Prevalence and heritability of handedness in a Hong Kong Chinese twin and singleton sample
Background Left-handedness prevalence has been consistently reported at around 10% with heritability estimates at around 25%. Higher left-handedness prevalence has been reported in males and in twins.

A relationship exists between cerebral dominance and right or left handedness. Left-hemisphere dominance occurs in 97% of right-handed people and in 70% of left-handed people.

Task complexity, age and gender effect on functional motor asymmetry of right- and left-handed children [PDF]
Manual asymmetry was assessed in different complexity coincidence-anticipation tasks in 59 right- and 56 left-handed children of both genders divided into two age groups (7-8 years and 9-10 years).

Testing the left-handedness of the b \to c transition [PDF]
We analyse the spin structure of inclusive semileptonic b \to c transitions and the effects of non-standard model couplings on the rates and the spectra. The calculation includes the {\cal O} (\alpha_s) corrections as well as the leading non-perturbative

Incidences of asymmetries for the palmar grasp reflex in neonates and hand preference in adults [PDF]
It was hypothesized that adult handedness might be predicted from the neonatal grasp reflex. Grasp reflex was measured from right and left hand (10 trials for each hand) in neonates.

Differences in cerebral cortical anatomy of left- and right-handers
The left and right sides of the human brain are specialized for different kinds of information processing, and much of our cognition is lateralized to an extent towards one side or the other.

Does handedness matter? Writing and tracing kinematic analysis in healthy adults [PDF]
Writing is a complex skill and it can be affected by many factors. One of the most obvious is handedness. The actual influence of handedness (especially left-handedness, since almost 10% of the population is left-handed) onto writing performance has not ...
