摘要/Abstract

摘要： 本文报道叶猴、金丝猴、长臂猿自由取食时的利手现象。本研究共用金丝猴12只(雄性8只,雌性4只),叶猴25只(雄性16只、雌性9只),长臂猿5只(雄性3只,雌性2只)。对每个动物而言,总观察次数不少于30次,其结果显示:在雄性金丝猴中,62.5％的动物显示右利,25％显示主利,12.5％无利手现象。在雄性叶猴中,62.5％的动物显示右利,18.7％显示左利,18.7％无利手现象。在3只雄性长臂猿中,2只显示右利,一只无利手现象。统计结果表明:雄性金丝猴有明显的右利手现象(P<0.05）, 雄性叶猴右利手现象接近显著(p=0.06), 长臂猿因观察数量太少,未进行统计。在上述三种动物中, 雌性个体无利手现象。本工作结果提示(1)雄性金丝猴, 叶猴在自由取食时具有右利手现象, 长臂猿也可能有右利手现象, (2)大脑两半球的不对称性与性别有关。

Abstract: The animals used in this research were 12 RH (male: 8, female: 4), 25PR (male: 16, female: 9) and 5HY (male: 3, female: 2). Each animal was observed more than 30 times. The results show that 62.5% male RH were right-handed, 25% were left-handed and 12.5% were both hand preference. ln male PR, 62.5% were right -handed, 18.7% were left-handed and 18.7% were both handed preference. In male Hy, two animals were right-handed, one animal was both-hand preference.
Statistic data of this research show that there was clear right-hand preference in male RH (P <0.05) and there was right-hand preference which approachs the clear level(P=0.06) in male PR. Data from HY were not calculated because of the limited number of animal we used.
In female RH, PR and HY, there were not deviation and laterality of hand preference.
