Hand to mouth in a Neandertal : right-handedness in regourdou 1 [PDF]
, 2012 We describe and analyze a Neandertal postcranial skeleton and dentition, which together show unambiguous signs of right-handedness. Asymmetries between the left and right upper arm in Regourdou 1 were identified nearly 20 years ago, then confirmed by ...

Cortex, 1978 The anxiety scores of 23 left-handed, 12 mixed-handed and 35 right-handed college students were compared with the result that right-handers were significantly less anxious then both the left and the mixed-handed groups (which did not differ statistically). Since these data appear to be unique, generalizations from them was thought to be premature.

Task complexity, age and gender effect on functional motor asymmetry of right- and left-handed children [PDF]
Motricidade, 2011 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).

Handedness of a motor program in C. elegans is independent of left-right body asymmetry. [PDF]
PLoS ONE, 2012 Complex animals display bilaterally asymmetric motor behavior, or "motor handedness," often revealed by preferential use of limbs on one side. For example, use of right limbs is dominant in a strong majority of humans. While the mechanisms that establish

PCSK6 is associated with handedness in individuals with dyslexia [PDF]
, 2010 Approximately 90% of humans are right-handed. Handedness is a heritable trait, yet the genetic basis is not well understood. Here we report a genome-wide association study for a quantitative measure of relative hand skill in individuals with dyslexia ...

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]
PLoS ONE, 2014 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
