Nonetheless, how tool use might spread throughout a population is still an open question. In order to answer that, we observed the behavior of inserting human hair or human-hair-like material between their teeth as if they were using dental floss in a group of long-tailed macaques (Macaca fascicularis) in Thailand. The observation was undertaken by video-recording the tool-use of 7 adult females who were rearing 1-year-old infants, using the focal-animal-sampling method. When the data recorded were analyzed separately according to the presence/absence of the infant of the target animal in the target animal's proximity, the pattern of the tool-using action of long-tailed adult female macaques under our observation changed in the presence of the infant as compared with that in the absence of the infant so that the stream of tool-using action was punctuated by more pauses, repeated more often, and performed for a longer period during each bout in the presence of the infant. We interpret this as evidence for the possibility that they exaggerate their action in tool-using so as to facilitate the learning of the action by their own infants.", "link"=>"http://www.mendeley.com/research/freeranging-macaque-mothers-exaggerate-toolusing-behavior-observed-offspring", "reader_count"=>101, "reader_count_by_academic_status"=>{"Unspecified"=>4, "Professor > Associate Professor"=>7, "Student > Doctoral Student"=>4, "Researcher"=>15, "Student > Ph.

This is the first evidence of the finding of this kind (as far as I know). It would be important to confirm this finding by similar observations with different types of tools and their usage; in macaques as well as in other species. This article may open a new direction of studying behavior of learning facilitation in pre-human species. Another direction of study should concentrate on a possibility of infant-directed vocalization associated with this behavior.
