Across time and place, right hand preference has been the norm, but what is the precise
prevalence of left-and right-handedness? Frequency of left-handedness has shaped and …

According to a longstanding view, sex differences in cognitive abilities such as mental
rotation or verbal memory arise from sex differences in hemispheric asymmetry: males are …

Left-handers are often excluded from study cohorts in neuroscience and neurogenetics in
order to reduce variance in the data. However, recent investigations have shown that the …

Knowing whether an individual prefers the left or right hand for skilled activities is important
to researchers in experimental psychology and neuroscience. The current study reports on a …

Our goal in this chapter is to provide a concise introduction to the study of left–right
asymmetries in brain and behavior from a comparative perspective. We consider evidence …

Handedness is the single most studied aspect of human brain asymmetries. For long it has
been thought to be a monogenic trait that can produce an asymmetrical shift of cerebral …

Functional preferences in the use of right/left forelimbs are not exclusively present in
humans but have been widely documented in a variety of vertebrate and invertebrate …

Since almost a hundred years, psychologists have investigated the link between hand
preference and dyslexia. We present a meta-analysis to determine whether there is indeed …

Surveys of Chinese students since the 1980s report that less than 1% are left-handed. This
is an extraordinarily low number given the generally accepted view that between 10 and …

Understanding the relationship between cerebral laterality and intelligence is important in
elucidating the neurological underpinnings of individual differences in cognitive abilities. A …
