A Marmoset By Any Other Name

Zoo Logic

Director of Research for the Dolphin Research Center, Dr. Kelly Jaakkola returns to discuss her upcoming free webinar summarizing recent dolphin cognition studies hosted by the Dolphin Communication Project and her just published invited rebuttal to a paper in the journal Science about marmosets supposed use of individual names. Few species have been shown to use names much like we humans do as labels to identify specific individuals. She discusses how authors of a recent study that relied on machine learning to analyze common marmoset "phee calls" found patterns which they suggest indicate the use of these calls as individual names. Dr. Jaakkola suggests in her rebuttal that while the computer methodology seems sound and exciting for future investigative work, there is another explanation which fits the data better than the authors' interpretation that marmosets are using these calls as names like humans or dolphins do.
