Thinking Chickens: A Review Of Cognition, Emotion, And Behavior In The Domestic Chicken, Lori Marino
Thinking Chickens: A Review Of Cognition, Emotion, And Behavior In The Domestic Chicken, Lori Marino
Lori Marino, PhD
Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. At least some birds are now known to be on par with many mammals in terms of their level of intelligence, emotional sophistication, and social interaction. Yet, views of chickens have largely remained unrevised by this new evidence. In this paper, I examine the peer-reviewed scientific data on the leading edge of cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities in …
Fallow Bucks Attend To Vocal Cues Of Motivation And Fatigue, Benjamin J. Pitcher, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott
Fallow Bucks Attend To Vocal Cues Of Motivation And Fatigue, Benjamin J. Pitcher, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott
Alan G. McElligott, PhD
Vocalizations encode a range of information about the caller, and variation in calling behavior and vocal structure may provide listeners with information about the motivation and condition of the caller. Fallow bucks only vocalize during the breeding season and can produce more than 3000 groans per hour. Males modulate their calling rates, calling faster when other calling males and/or females are nearby. Groans also reveal caller fatigue, becoming shorter and higher pitched toward the end of the rut. Thus, fallow deer groans vary both over very short (minute to minute) and longer timescales (the rut). However, no studies have investigated …

Orangutan Pantomime: Elaborating The Message, Anne Russon, Kristin Andrews
Orangutan Pantomime: Elaborating The Message, Anne Russon, Kristin Andrews
Kristin Andrews, PhD
We present an exploratory study of forest-living orangutan pantomiming, i.e. gesturing in which they act out their meaning, focusing on its occurrence, communicative functions, and complexities. Studies show that captive great apes may elaborate messages if communication fails, and isolated reports suggest that great apes occasionally pantomime. We predicted forest-living orangutans would pantomime spontaneously to communicate, especially to elaborate after communication failures. Mining existing databases on free-ranging rehabilitant orangutans’ behaviour identified 18 salient pantomimes. These pantomimes most often functioned as elaborations of failed requests, but also as deceptions and declaratives. Complexities identified include multimodality, re-enactments of past events and several …
Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews
Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews
Kristin Andrews, PhD
We recently demonstrated, by mining observational data, that forest-living orangutans can communicate using gestures that qualify as Pantomime. Pantomimes, like other iconic gestures, physically resemble their referents. More elaborately, pantomimes involve enacting their referents. Holding thumb and finger together at the lips and blowing between them to mean balloon is one example. Here we sketch evidence of pantomime in other great apes, methodological concerns, and sophisticated cognitive capabilities that great ape pantomimes suggest.
