Behavioral decisions made under the risk of predation: a review and prospectus

There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cogni- tive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mecha- nism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors (e.g., alarm, social facilitation, vicar- iousness of emotions, mother-infant responsiveness, and the modeling of competitors and predators) that are crucial for the reproduc- tive success of animals living in groups. The Perception-Action Model (PAM), together with an understanding of how representations change with experience, can explain the major empirical effects in the literature (similarity, familiarity, past experience, explicit teach- ing, and salience). It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empa- thy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of de- velopment, and situations.

Empathy: Its ultimate and proximate bases.

Adaptive goal-directed behavior involves monitoring of ongoing actions and performance outcomes, and subsequent adjustments of behavior and learning. We evaluate new findings in cognitive neuroscience concerning cortical interactions that subserve the recruitment and implementation of such cognitive control. A review of primate and human studies, along with a meta-analysis of the human functional neuroimaging literature, suggest that the detection of unfavorable outcomes, response errors, response conflict, and decision uncertainty elicits largely overlapping clusters of activation foci in an extensive part of the posterior medial frontal cortex (pMFC). A direct link is delineated between activity in this area and subsequent adjustments in performance. Emerging evidence points to functional interactions between the pMFC and the lateral prefrontal cortex (LPFC), so that monitoring-related pMFC activity serves as a signal that engages regulatory processes in the LPFC to implement performance adjustments.

The fifty-seven original essays in this book provide a comprehensive overview of the interdisciplinary field of animal cognition. The contributors include cognitive ethologists, behavioral ecologists, experimental and developmental psychologists, behaviorists, philosophers, neuroscientists, computer scientists and modelers, field biologists, and others. The diversity of approaches is both philosophical and methodological, with contributors demonstrating various degrees of acceptance or disdain for such terms as "consciousness" and varying degrees of concern for laboratory experimentation versus naturalistic research. In addition to primates, particularly the nonhuman great apes, the animals discussed include antelopes, bees, dogs, dolphins, earthworms, fish, hyenas, parrots, prairie dogs, rats, ravens, sea lions, snakes, spiders, and squirrels.The topics include (but are not limited to) definitions of cognition, the role of anecdotes in the study of animal cognition, anthropomorphism, attention, perception, learning, memory, thinking, consciousness, intentionality, communication, planning, play, aggression, dominance, predation, recognition, assessment of self and others, social knowledge, empathy, conflict resolution, reproduction, parent-young interactions and caregiving, ecology, evolution, kin selection, and neuroethology.

Animal play : evolutionary, comparative, and ecological perspectives

The development of social interaction was studied in infant coyotes, beagles, and wolves. In this paper, social play behavior is discussed. Social play may be characterized in a number of ways: (i) actions from various contexts are incorporated into labile (unpredictable) temporal sequences; (ii) the “play bout” is typically preceded by a metacommunicative signal which indicates “what follows is play”; these signals are also observed during the bout; (iii) certain actions may be repeated and performed in an exaggerated manner; (iv) the activity appears “pleasurable” to the players.

By comparing these three species, some insight into the dynamics of social play may be gained. Coyotes were the least successful in soliciting play. When they did play, 90% of all bouts had been previously solicited. Coyotes also tended to use the most successful signals most frequently. This trend was not observed in the beagles or the wolves. By taking into account the fact that infant coyotes are significantly more aggressive than either infant wolves or beagles, the differential ontogeny of social play can be explained. Some of the functions of social play in canids are discussed, and it is concluded that social play is a valid class of social behavior and lends itself nicely to quantitative study.

Social play and play-soliciting by infant canids

Scientists have long counseled against interpreting animal behavior in terms of human emotions, warning that such anthropomorphizing limits our ability to understand animals as they really are. With "Wild Justice", Marc Bekoff and Jessica Pierce unequivocally challenge this long-held view. Marrying years of behavioral and cognitive research with compelling and moving anecdotes, Bekoff and Pierce reveal that animals exhibit a broad repertoire of moral behaviors, including fairness, empathy, trust, and reciprocity. Animals, in short, are incredibly adept social beings, relying on rules of conduct to navigate intricate social networks that are essential to their survival. Ultimately, Bekoff and Pierce draw the astonishing conclusion that there is no moral gap between humans and other species: morality is an evolved trait that we unquestionably share with other social mammals.

Wild Justice: The Moral Lives of Animals

Actions called play signals have evolved in many species in which social play has been observed. Despite there being only few empirical demonstrations, it generally is accepted that play signals are important in the initiation ("I want to play") and maintenance ("I still want to play") of ongoing social play. In this study I consider whether a specific and highly stereotyped signal, the bow, is used to maintain social play in adult and infant domestic dogs, infant wolves, and infant coyotes. To answer this question the temporal placement of bows relative to actions that are also used in other contexts (dominance or predatory encounters) such as biting accompanied by rapid side-to-side shaking of the head was analyzed to determine if bows performed during ongoing social play are used to communicate the message "I want to play despite what I am going to do or just did - I still want to play". The non-random occurrence of bows supports the hypothesis that bows are used to maintain social play in these canids when actions borrowed from other contexts, especially biting accompanied by rapid side-to-side shaking of the head, are likely to be misinterpreted.
