在两种姿势调整条件下，在40只黑猩猩（Pan troglodytes）和9只猩猩（Pongo pygmaeus）的手偏好进行了评估。姿势条件是四足直立，在此期间，达到食物评分至少50次试验。结果表明，在四足达成没有人口的偏好，但右手人口的偏好，发现在直立达成。有没有显着的影响，年龄或性别的手偏好的方向或强度。早期养育史影响了手偏好的强度，但不影响方向。结果表明，姿势是评估类人猿手部偏好的一个重要因素，可能具有重要的进化后果。
Hand preference in reaching was assessed under 2 postural adjustment conditions in 40 chimpanzees (Pan troglodytes) and 9 orangutans (Pongo pygmaeus). The postural conditions were quadrupedal and upright, during which reaching for food was scored on a minimum of 50 trials. Results indicated no population preference during quadrupedal reaching but a right-hand population preference was found during upright reaching. There were no significant effects of age or sex on either the direction or strength of hand preference. Early rearing history affected the strength of hand preference but not direction. The results suggest that posture is an important factor in the assessment of hand preference in great apes and may have important evolutionary consequences.
