Do Actions Speak Louder Than Words? Communicative Frequencies And Multimodality In Ring-Tailed Lemurs (Lemur Catta), Hilary Hager
Electronic Thesis and Dissertation Repository
The study of multimodal communication in primatology has increased only recently. At present, there are no on-going investigations of multimodal communication in ring-tailed lemurs (Lemur catta), despite the body of research on this species. I investigated how different modes of L. catta inter-individual multimodal communication are socially coordinated and integrated by examining frequencies of occurrence within four potential biological and social factors: age, troop affiliation, sex, and dominance rank. Research was conducted over four months at the Duke Lemur Center, Durham, NC, on 14 individuals from three separate troops of captive, free-ranging L. catta. Results demonstrate communicative …

Although some animals, such as elephants, can use olfaction to discriminate quantities of food, previous research suggested dogs cannot smell the difference between quantities of hot dog slices. In the experiments reported here, dogs were allowed to smell two opaque containers under which were placed different numbers of hot dog slices, and then were allowed to make a choice between containers. In Experiment 1, dogs chose between one and five hot dog slices and chose the larger quantity at an above chance level. In Experiment 2 and Experiment 3, I tested whether dogs conformed to the distance effect and/or the …
