目的:评估大学生群体优势眼和左/右利手间的关系.方法:受试对象为179名大学生志愿者,平均年龄为19.4±1.6岁,其中女110 名(61.5%),男69 名(38.5%).优势眼由Gündoan和McManus两种方法测得,左或右利手则由Edinburgh Handedness Inventory Oldfield和McManus法确定,t检验评估实验的可信度.结果:Gündoan法测得受试者中110人(61.5%)为右眼优势,69人(38.5%)为左眼优势,无性别差异.McManus法重测相同受试者,则右/左眼优势分别为128人(71.5%)和51人(28.5%).两法测得的结果相关,一致度κ=0.256(P<0.01).女性受试者中,Gündoan法测得右/左眼优势分别为62人(56.4%)和48 人(43.6%),McManus法测得的结果为右/左眼优势分别为74人(67.3%)和36人(32.7%).Fisher检验两法测得的结果相关(P<0.05),一致度κ=0.239 (P<0.01).男性受试者中,Gündogan法测得右/左眼优势为48 人(69.6%)和21人(30.3%),McManus法检测为54人(78.3%)和15人(21.7%).Fisher检验两法测得结果相关(P>0.05),一致度κ=0.239(P<0.01).Oldfield和McManus法分别测得右利手比例为91.6%(n=164)和91.1% (n=163),两者间有较高的一致度κ=0.753(P<0.01).McManus法检测出的优势眼和左或右利手间的统计学相关性具有显著性意义(Fisher检测P<0.017;一致度评分phi=0.193(P<0.05).结论:大学生以右利手为主,McManus法检测发现右利手似乎与有眼优势更为相关.左或右利手和优势眼似乎是研究大脑功能不对称性和大脑偏侧型的最可靠的方法.

AIM: To evaluate the relationship between eye dominance and hand preference among university students with respect to dominant hemisphere. METHODS: A total of 179 university students (mean age ±SD was 19.4±1.6 years) were included in the study. The subject population was composed of 110 females (61.5%) and 69 males (38.5%) volunteered for examina-tion. Eye dominance was determined by two different methods named Gündoan and McManus tests. Handed-ness was also determined by two different methods as Edinburgh Handedness Inventory Oldfield (1971) and McManus tests. The reliability of the survey was examin-ed using a test-retest method.RESULTS: Without gender difference right/left eye dominance were found respectively for 110 (61.5%), 69 (38.5%) subjects by Gündoan test. When the same subjects were re-tested by McManus method the right/left eye dominance was found respectively for 128 (71.5%), 51 (28.5 %). The results of these two methods were related significantly, with an agreement score κ=0.256 (P<0.01). In females the right/left eye dominance were found respectively as 62 (56.4%), 48 (43.6%) by Gündoan test as it was found respectively 74 (67.3%), 36 (32.7%) for the same subjects when re-tested by McManus test method. The results of these two tests for females were related significantly by Fisher exact test (P<0.05), with agreement score κ=0.239 (P<0.01). In males the right/left eye dominance were found respectively as 48 (69.6%), 21 (30.3%) in Gündoan test method as it was found 54 (78.3%), 15(21.7%) for the same subjects when re-tested by McManus test (P>0.05). Right handedness ratios were 91.6% (n=164) and 91.1% (n=163) in Oldfield and McManus tests, respec-tively. Statistical agreement between these two methods was also represented with a high score (κ=0.753, P<0.01). The statistical relationship correlation between eye dominance and throwing hand was found significant by McManus test methods (Fisher exact test P<0.017) with an agreement score phi=0.193, P<0.05.CONCLUSION: The marked right handedness was observed among university students in both two hand preference tests. According to McManus test the throwing hand seems to have more consistent relation with the right eye dominance. Throwing hand and dominant eye seems to be a most reliable way for detecting functional asymmetry and cerebral laterality.
