One-hundred and nine consistent left- and right-handers participated in an experiment investigating the role of Handedness, Sex, and College Major in predicting spatial talents, verbal problems, immune disorders, allergies, and myopia. Left-handers had poor verbal ability. Males in spatial majors (requiring extensive math) had high spatial ability and poor verbal ability. Left-handed males in spatial majors had high spatial ability, poor verbal ability, an elevated incidence of asthma, and a marginally higher incidence of myopia. No trade-off between spatial and verbal ability was found. Results provide qualified support for Geschwind and Galaburda's (1987) hypothesis of the "Pathology of Superiority."
109名惯用右手和左手的人参与了一项实验，该实验旨在研究用手习惯、性别和大学专业在预测空间天赋、语言问题、免疫紊乱、过敏和近视方面的作用。左撇子的语言能力较差。就读于空间专业（需要大量数学知识）的男性具有较高的空间能力，但语言能力较差。就读于空间专业的左撇子男性具有较高的空间能力、较差的语言能力、较高的哮喘发病率以及略高的近视发病率。未发现空间能力和语言能力之间存在权衡。研究结果为盖什温德（Geschwind）和加拉布尔达（Galaburda）（1987年）的“优势病理学”假说提供了有限的支持。
