  • Title: Hand preference in the use of tools by infant baboons (Papio cynocephalus anubis).
    Author: Westergaard GC.
    Journal: Percept Mot Skills; 1993 Apr; 76(2):447-50. PubMed ID: 8483654.
    Abstract:
    Hand preference in the use of tools was examined in a peer group of five infant baboons, Papio cynocephalus anubis. Hand preference was noted for all subjects on a sponging task and for one subject on a probing task. The baboons exhibited the highest percentage of bimanual actions on the initial segment of each three-component task. These results are consistent with the hypothesis that immature nonhuman primates exhibit lateral asymmetries when they use tools and bimanual coordination when they perform complex manipulative tasks.
