OBJECTIVES/HYPOTHESIS To investigate the relationship between handedness and the incidence of squamous cell carcinoma in the external auditory canal (EACSCC). MATERIALS AND METHODS Sixty-eight cases of EACSCC were enrolled in this study, and their affected side was checked. Handedness and ear-picking habits were also investigated in 34 EACSCC cases. Handedness was judged based on self-categor...

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 interpreted as evidence in favour of frequency-dependent selection mechanisms to explain the maintenance of left-handedness in humans. To test...

Evidence for population-level right-handedness in nonhuman primates seems inconsistent and contradictory, and many hypotheses have been advanced to account for this volatility. Funnel plots (scatter plots of percent right-hand use vs. sample size) offer a straightforward graphical technique for assessing: 1) the strength and consistency of handedness, 2) whether variability is consistent with n...

Research has suggested that brain hemispheres play different roles in processing belief systems, the RH serving to update beliefs while LH acts to hold beliefs constant (Ramachandran, 1995). Degree of handedness is thought to be directly related to amount of interhemispheric interaction in the brain (Christman, 2001). Niebauer (2004) correlated degree of handedness with beliefs in creationism a...
