The relationship between Revised Reinforcement Sensitivity Theory (rRST), handedness and indecision [PDF]

, 2013
Indecisiveness is an inability to make a decision, manifest across a number of behaviours. We explore the influence that both direction and strength of hand preference may have on this construct, examining it in relation to the revised Reinforcement ...

The level of the aggression in karate athletes with different handedness and belt grades [PDF]

Journal of Men's Health
Karate athletes with different lateral talents possess different functions in terms of skills and personality characteristics in a way that handedness can be considered an advantage.

Possible origins of macroscopic left-right asymmetry in organisms

, 2012
I consider the microscopic mechanisms by which a particular left-right (L/R) asymmetry is generated at the organism level from the microscopic handedness of cytoskeletal molecules.

Are left-handers really more anxious? [PDF]

, 2012
Research examining anxiety and handedness is inconclusive. Davidson and Schaffer (1983) found left-handers had higher trait anxiety, while Beaton and Moseley (1991) found no state or trait differences. Such studies potentially have methodological issues,

Role of HLA-A in Handedness

Medicine Science, 2015
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.

A model balancing cooperation and competition explains our right-handed world and the dominance of left-handed athletes

, 2011
An overwhelming majority of humans are right-handed. Numerous explanations for individual handedness have been proposed, but this population-level handedness remains puzzling. Here we use a minimal mathematical model to explain this population-level hand

Gravity and handedness of photons [PDF]

, 2017
Vacuum fluctuations of quantum fields are altered in presence of a strong gravitational background, with important physical consequences. We argue that a non-trivial spacetime geometry can act as an optically active medium for quantum electromagnetic ...

Kin selection as a modulator of human handedness: sex-specific, parental and parent-of-origin effects

Evolutionary Human Sciences
The frequency of left-handedness in humans is ~10% worldwide and slightly higher in males than females. Twin and family studies estimate the heritability of human handedness at around 25%.

Brain handedness associations depend on how and when handedness is measured

Scientific Reports
Hand preference is ubiquitous, intuitive, and often simplified to right- or left-handed. Accordingly, differences between right- and left-handed individuals in the brain have been established. Nevertheless, considering handedness as a binarized construct
