Aloha Colleagues, I am happy to inform you about the following recent publication from the University of Hawaii at Hilo Pack Marine Mammal Laboratory. Correspondence about this book chapter can be directed to myself at pack@hawaii.edu. Wishing you all a healthy, safe, enjoyable and peaceful holiday season. Best, Adam Pack A. A. (2021). Dolphin Social Cognition. In: A. B. Kaufman, J. Call & J. C. Kaufman (Eds.), The Cambridge Handbook of Animal Cognition (pp. 383-414). Cambridge University Press, United Kingdom. In 2006, Pack and Herman published a seminal article entitled "Dolphin social cognition: Our current understanding" (Aquatic Mammals, 32, 443-460). In the current book chapter "Dolphin Social Cognition," Pack provides a comprehensive updated review of social cognition in dolphins that covers a broad range of topics including: social memory, vocal imitation of other dolphins and computer-generated arbitrary sounds, motor imitation of another dolphin's behavior, imitation of a referenced model's motor behaviors, jointly coordinated cooperative behavior, social awareness and attention, initial studies of joint attention in dolphins, the dolphin's cognitive flexibility in processing variations of pointing and gaziing cues, comprehension of dynamic-sustained pointing and gazing cues in test-naive dolphins, testing for the dolphin's understanding of the geometry of pointing and gazing cues, tests of the dolphins understanding of the identity of what is being gazed at or pointed to, spontaneous production of pointing cues by a dolphin and attention to its audience, and evaluating evidence of "theory of mind" in dolphins. -- Adam A.
