Lateral preferences are strange, puzzling, and on the surface, not particularly adaptive aspects of behavior. Why one chooses habitually to write or to brush the teeth with the right hand, while a friend or family member habitually uses the left hand, might be interesting enough to elicit some conversation over dinner or a drink, but certainly does not seem to warrant serious scientific study. Yet when one looks at human behaviors more carefully, one becomes aware that asymmet rical behaviors favoring one side or the other are actually a fairly universal characteristic of human beings. In the same way that we are right or left handed, we are also right or left footed, eyed, and eared. As a species, we are quite lopsided in our behavioral coordinations; furthermore, the vast majority of us are right sided. Considering that we are looking at a sizable number of behaviors, and at a set of biases that seem to be systematic and show a predictable skew in the popUlation, the problem takes on greater significance. The most obvious form of lateral preference is, of course, handedness. When studying behavioral asymmetries, this is the issue with which most investigators start. Actually, we entered this research area through a much different route. Around 1971 we became interested in the problem of eye dominance or eye preference. This is a behavior where the input to one eye seems to be preferred over that to the other in certain binocular viewing situations.

Nine out of every ten human beings are naturally right-handed. Those who were not right-handed were feared, shunned, or forcibly retrained in many periods and cultures. Indeed, some members of fundamentalist sects still regard left-handers as in league with the devil, and prejudices against left-handers are reflected in the multiple associations of right with good and left with bad that have become enshrined in everyday language and folklore. A “left-handed compliment” is actually an insult, and the dictionary definition of left-handed includes the terms “awkward,” “clumsy,” “ill-omened,” and “Illegitimate.” In his summary of scientific research into sidedness, Stanley Coren rapidly dismisses the notion of the southpaw as somehow tainted. Increasingly we are coming to understand, however, that left-handedness does have social, educational, medical, and psychological implications. Coren uses entertaining examples to illuminate the paths of research he has followed, and answers vitally important questions such as: What are the neuropsychological and behavioral implications of differences for left-handers themselves, as well as for their parents, teachers, spouses, children, counselors, and physicians? How can we determine our own patterns of sidedness? Are they encoded in our genes? And, very importantly, how can we make the world more comfortable and safer for left-handers? Coren persuasively argues that left-handers are an invisible minority who must define themselves and organize for self-protections in the same way that more visible minorities have done. Much (though not all) of the risk to which left-handers are exposed derives from the fact that the tools they use and the machines they operate are designed for right-handers, a flaw that given heightened public awareness would be easy to correct. Coren advocates a change in the way the right-handed majority treats its left-handed minority to eliminate the risks left-handers face.
