食蟹猴取食位置偏好及改变的行为学研究

Behavior study of feeding site preference and change in the Cynomolgus monkey (Macaca fascicularis)

偏好行为被认为是研究大脑半球功能偏侧性调控表达的一种预测指标（Elias et al.,1998）。偏好行为与大脑解剖结构和功能不对称之间关系的研究表明人类明显偏爱使用右手,是由大脑左半球控制（Zhao et al.,2010;崔媛媛,2012;付卫伟,2012）,而手偏好正是大脑皮层结构和功能不对称最基本的行为表现.

Eight adult Macaca fascicularis subjects（ four males and four females） were collected between August 2013 to May 2014 and were divided into four same-sex groups. The intergroup differences of social status were determined via video,and a behavior study of feeding site preference and change was designed. Our results revealed that Macaca fascicularis subjects have significant feeding sit preference（ 75%）,but it can be changed（ 87. 5%）. Exploratory behavior is closely related to the change of feeding site preference. Male exploratory behaviors were more frequent than those of females,which may be associated with the closer proximity and relationships between females and males in the macaque colony structure. The exploratory behavior scores of high-status females were higher than those of low-status females. Therefore,gender and social status are important factors which can influence exploratory behavior. This study provided the evidence for pointing cues experiment,and new idea and direction for the research on brain functional asymmetry.
