We examined lateral bias for looking, reaching, and turning in 33 tufted capuchin monkeys (Cebus apella) comprising 29 parent-offspring dyads (13 mother-offspring dyads and 16 father-offspring dyads). We found evidence for maternal and paternal contributions to the direction of looking bias but no evidence for contribution from either parent to the direction of reaching bias. Further, we found evidence of differential maternal and paternal influences on the direction of offspring turning bias. Finally, we found no evidence of parental contribution to the strength of lateral bias for any of our measures. Our results indicate that parental contributions to lateral bias in humans and apes may not correspond to those in monkeys.
我们研究了33只簇绒卷尾猴（僧帽猴属）的注视、伸手和转身的侧向偏好，这些猴子包括29个亲子对（13个母婴对和16个父子对）。我们发现有证据表明母亲和父亲对注视偏好方向有影响，但没有证据表明父母对伸手偏好方向有影响。此外，我们发现有证据表明母亲和父亲对后代转身偏好方向有不同影响。最后，我们没有发现父母对我们任何测量指标的侧向偏好强度有影响的证据。我们的结果表明，人类和猿类中父母对侧向偏好的影响可能与猴子不同。
