对109只黑猩猩(类人猿)进行了双手协调任务的手部偏好评估。使用手的次数和频率对4个测试阶段的手偏好进行评估,以比较每个分析水平在评估手性个体差异方面的敏感性。总体而言,使用几种不同的手使用测量方法发现了显著的人口水平的右撇子。基于回合数和频率的利手性指数呈高度显著相关。此外,尽管在每次测试中都努力进行情境偏见偏好,但在测试中,手的偏好是一致的。综上所述,这些数据并不支持回合是评估手偏好的更好分析水平的观点。结果进一步表明,对协调的双手动作的偏好不受情境因素的影响,可能反映了左半球运动技能的固有专门化。(PsycINFO数据库记录(c) 2016 APA,版权所有)
Hand preferences for a coordinated bimanual task were assessed in 109 chimpanzees (Pan troglodytes). Hand preference was evaluated for 4 test sessions using bouts and frequencies of hand use to compare the sensitivity of each level of analysis in evaluating individual variation in handedness. Overall, significant population-level right-handedness was found using several different measures of hand use. Handedness indices based on bouts and frequencies were highly and significantly correlated. Moreover, hand preferences were consistent across tests despite efforts to situationally bias preference during each test. Taken together, these data do not support the view that bouts are a better level of analysis for evaluating hand preference. The results further suggest that hand preferences for coordinated bimanual actions are not influenced by situational factors and may reflect an inherent specialization of the left hemisphere for motor skill.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
