优势眼测量法的研究(英文)

A study on dominant eye measurement

目的:为了检查一项新的性能测试,对同以受试者用两种不同的方法进行检测和再测试,并比较和讨论这些检测方法的可靠性。方法:共179个大学生(平均年龄±标准差为19.37±1.62)a自愿参加这项由110名女性(61.5%)和69名男性(38.5%)组成的调查。优势眼由两种不同的方法检测,一个为McManus方法,一个为Gndo■an方法。利用SPSS的重测信度的可靠性分析保证该项调查的可靠性。结果:McManus方法检测128名(71.5%)参加者右眼为优势眼,无性别差异。同样利用Gndogˇan方法再检测发现110名(61.5%)参加者右眼为优势眼。两种方法的检测结果由Fisher确切概率法分析发现呈显著性相关(P<0.01),一致性数值为为κ=0.256,P<0.001。利用Mc-Manus法发现女性参加者中74名(67.3%)右眼为优势眼,36名(32.7%)左眼为优势眼。利用Gndog■an法再检测发现62名女(56.4%)右眼为优势眼,48名女(43.6%)左眼为优势眼。通过Fisher确切概率法分析发现McMa-nus和Gndo■an两种方法在女性优势眼检测方面呈显著性相关(P<0.05),一致性数值为κ=0.239,P<0.01。在男性参与者中,通过McManus法检测右眼优势眼为54眼(78.3%),左眼优势眼为15眼(21.7%),利用Gndo■an法再检测右眼优势眼为48眼(69.6%),左眼优势眼为21眼(30.4%)。利用χ2检验和Fisher确切概率法分析数据。利用Kappa一致性检验分析不同方法的一致性。比例的比较由z检验完成,P值小于0.05为差异显著。结论:通过检测观察到女性和男性均以右眼优势眼为主,没有性别差异。右眼优势这种功能性偏侧化现象可能是由于大脑左半球的主导作用造成的。这对于将来在一侧面偏重方面的研究很重要,也许会成为一个重要的模式系统。

AIM： To examine a new performance test for detecting eye dominance by testing and re-testing with two different methods of the same subjects for comparing and discussing the reliabilities of these tests. METHODS： A total of 179 university students （mean age ＋ SD was 19. 37±1. 62 years） were voluntarily participate in this survey consisting of 110 females （61.5%） and 69 males （38.5%）. Eye dominances were determinec by two different methods which were named McManus and a Gvndogan tests. The reliability of the survey was examined using a test-retest method. RESULTS： Without sex difference right eyes were found dominant for 128 （71.5 % ） participants by McManus test. The same subjects were re-tested by Gundogan method, the right eye dominance were found for 110 （61. 5%） subjects. The results of these two methods were related significantly by Fisher Exact test （ P 〈 0. 01 ）, with an agreement scores （K = 0. 256, P 〈 0. 001 ）. In females the right eye dominance were found for 74 （67.3%） and left eye were found for 36 （32.7%） by McManus test. When the same subjects were re-tested by GOndoOan method the right eye dominance was found as 62 （56.4 %） ; and the left eye dominance was found for 48 （43. 6 %） subjects. McManus and GLindogan methods results for females were related significantly by Fisher Exact test （ P〈 0.05）, with a weak agreement scores （κ= 0. 239, P 〈 0.01 ）. In males the right/left eye dominance were found respectively 54 （78.3 %）, 15（21.7 %） in McManus test as it was found as 48 （69.6 %）, 21 （30.4 %） for the same participants when they re-test by GLindogan method. （X^2 test and Fisher exact test were used for the analysis of categorical data. The agreement between different methods was analyzed with Kappa statistics. Comparison of proportions was made by two proportions z test. P value less than 0.05 was considered as significant. CONCLUSION： Without gender difference and also in both females and males marked right eye dominance was observed. The right eye dominance was considering functional laterality may due to the dominance of left hemisphere instead of right hemisphere. It is an important topic future research in laterality, and it may well become an important model system for future research.
