Do Elephants Show Empathy (2008, background): “Several experimental paradigms have been developed to test mental-state and emotional-state recognition in primates ( Hare et al., 2000; Hare, Call and Tomasello, 2001; Parr, 2001), but adapting these tests to non-primate species often proves difficult and lacks ecological validity.”
Domestic goats, Capra hircus, follow gaze direction and use social cues in an object choice task (2005, background): “For example, they could be tested for their ability to follow gaze direction behind barriers or past distractors (Tomasello et al. 1999), or they could be tested with conspecifics in their ability to discern whether a competitor is or is not able to see food behind a barrier ( Hare et al. 2000, 2001”
Seeing it their way: evidence for rapid and involuntary computation of what other people see. (2010, methodology): “The visual perspective-taking task we chose is similar to the type of tasks that infants and chimpanzees can perform successfully (Hare et al., 2000; Sodian et al., 2007).”
Darwin's mistake: Explaining the discontinuity between human and nonhuman minds (2008, neutral): “A few years ago, however, Hare et al. (2000; 2001) reported " breakthrough " evidence that chimpanzees do, in fact, reason about certain psychological states in their conspecifics (see, particularly, Tomasello et al. 2003a; 2003b).”
Evidence from four lemur species that ringtailed lemur social cognition converges with that of haplorhine primates (2011, positive): “To distinguish between different mechanistic hypotheses, future research will need to replicate and extend work designed to assess similar cognitive skills in haplorhines (Hare et al. 2000, 2003; Flombaum & Santos 2005; Burkart & Heschl 2007).”
Chimpanzees are more skilful in competitive than in cooperative cognitive tasks (2004, background): “The fact is that the paradigms in which chimpanzee social-cognitive skills have been most impressively displayed are all basically competitive in nature (Hare et al. 2000, 2001).”
Social cognition by food-caching corvids. The western scrub-jay as a natural psychologist (2007, background): “Hare et al. (2000) placed a subordinate and a dominant individual in competition with one another for two food rewards, one of which was positioned such that it was visible only to the subordinate.”
Elephant cognition in primate perspective (2009, background): “In addition, field observations suggest that monkeys and apes are able to understand the geometric perspective of others (Byrne & Whiten, 1992); this has been confirmed ex perimentally only in the case of the chimpanzee ( Hare, Call, Agnetta, & Tomasello, 2000 ).”
Cache protection strategies by western scrub-jays, Aphelocoma californica: implications for social cognition (2005, background): “At present the ability to understand what others can and cannot see and to attribute knowledge states appears to be restricted to the great apes (Kummer et al. 1996; Hare et al. 2000; but see Karin-D’Arcy & Povinelli 2002).”
Intelligence in Corvids and Apes: A Case of Convergent Evolution? (2009, background): “Both western scrub-jays and chimpanzees behave differently when a competitor saw food hidden, and when they did not (Hare et al. 2000; Dally et al. 2005).”
Cross-species variation in gaze following and conspecific preference among great apes, human infants and adults (2014, background): “…as a methodological lesson, the species variation in sensitivity to the allospecific gaze suggests the importance of using conspecific models in comparative studies of gaze following and perhaps any social behaviours relying on gaze following (also see Hare et al., 2000; Tomasello et al., 1998).”
