LEFT-HANDEDNESS AND RISK OF BREAST CANCER: ABUNDANCE OF CONFLICTING DATA Z. Stoyanov, P. Nikolova The present short review summarizes controversial data regarding the putative association between left-handedness and breast cancer. Factors thought to be involved in the etiology and pathogenesis of breast cancer are outlined: prenatal and postnatal levels of sex steroids, maternal age, age at men...

A growing body of evidence is reviewed showing that degree of handedness (consistent versus inconsistent) is a more powerful and appropriate way to classify handedness than the traditional one based on direction (right versus left). Experimental studies from the domains of episodic memory retrieval, belief updating/cognitive flexibility, risk perception, and more are described. These results su...

Although the relationship of handedness to the ability to talk has been known to the ancients (Psalm 137, for example) the exact knowledge of anatomical underpinnings of this relationship at the public level is a new understanding. This article pursues another corollary of the anatomy sustaining laterality of motor control, i.e. the variability of the alien/unruly hand in patients who have suff...

Asymmetry of the planum temporale in relation to handedness, gender, and dyslexia is reviewed. The frequency of rightward asymmetry is rather higher than are estimates of the proportion of right hemisphere speech representation in the general population. Conversely, the frequency of leftward asymmetry is lower than the proportion of the population with left hemisphere speech. Neuro-anatomic asy...

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 toward one side or the other. Handedness is a reflection of nervous system lateralization. Roughly ten percent of people are mixed- or left-handed, and they show an elevated rate of reductions or reversals of some cerebral functional as...

The effect of handedness on cognitive functioning has been the subject of much controversy. The influential "pathological left-handedness theory" posited by Coren and Halpern (1991) claims that left-handedness is probabilistically related to deviations from the neurological and cognitive norm. Many studies have failed to find negative effects of left-handedness on cognitive functioning, but mos...
