在49只黑猩猩中研究了手偏好与接近-回避行为之间的关系。学生在连续4天的时间里被呈现2组新的物体。在每个会话期间，对象被呈现2小时，并且对于每个S记录触摸任何对象的延迟。然后比较了被确定为非右撇子或右撇子的黑猩猩的潜伏期分数。右利手的学生比非右利手的学生更快地接近和触摸物体。此外，男性触摸物体的速度明显快于女性。在接近回避行为的相关性是显着的刺激集和测试天。整体结果支持最近的理论模型连接半球的专业化表达的积极和消极的情感行为。
The relationship between hand preference and approach-avoidance behavior was examined in 49 chimpanzees (Pan). Ss were presented with 2 sets of novel objects on 4 consecutive days. The objects were presented for 2 hr during each session, and latency to touch any object was recorded for each S. Latency scores were then compared for chimpanzees that had been determined to be non-right- or right-handed. Right-handed Ss approached and touched the objects significantly faster than non-right-handed Ss did. In addition, males touched the objects significantly faster than did females. Correlations in approach-avoidance behavior were significant across stimulus sets and days of testing. The overall results support recent theoretical models linking hemispheric specialization with the expression of positive and negative affective behaviors.
