Stephen with a ph dog blog. Categorical learning in pigeons: The role of texture and shape in complex static stimuli. Create an account to follow your favorite communities and start taking part in conversations. This approach has given us a number of more or less standard tasks that have been successfully adapted for use with a wide range of species. For each domain, we evaluate the position of dog cognition, as either similar or different to that of the comparator species.
Banszegi, O., Jacinto, E., Urrutia, A., Szenczi, P., & Hudson, R. Can but don't: Olfactory discrimination between own and alien offspring in the domestic cat. For example, if one object is partly hidden (occluded) by another, pigeons do not respond to it as though the entire object was still there (Sekuler, Lee, & Shettleworth, 1996); but dogs, like humans, apparently recognize the continuing solidity of the occluded object (Pattison, Miller, Rayburn-Reeves, & Zentall, 2010). Huber, L., Popovová, N., Riener, S., Salobir, K., & Cimarelli, G. Would dogs copy irrelevant actions from their human caregiver? Premature death in dogs with nontraumatic hemoabdomen and splenectomy with benign histopathologic findings in: Journal of the American Veterinary Medical Association Volume 260 Issue S1 (2022. Ways, to depend upon—the feedback they receive from others, such as that provided by expressions of praise and blame. Preliminary phase 1 data on the safety and efficacy of a novel PET radiotracer, 124I-p5+14, for imaging systemic amyloidosis.
12 Unexplained or unexpected early death is a clinically relevant finding in this population, but there is a paucity of sufficiently large studies to support these findings. An analysis of visual oddity concept learning in a California sea lion (Zalophus californianus). 2020 10 28; 40(44):8573-8586.. View in PubMed. An interesting special case of motor imitation is "overimitation, " where an observer repeats a demonstrator's actions, including responses that are not necessary to achieve the goal; the opposite, the omission of unnecessary actions, has been called "rational imitation, " because it can be argued to demonstrate a fuller understanding of the situation (Gergely, Bekkering, & Kiraly, 2002). Understanding of object properties by sloth bears, Melursus ursinus. The welfare of dogs in human care (Chapter 14) - The Domestic Dog. Dogs do solve the simplest string-pulling tasks, with strings leading directly to the target object; where they fail is with multiple strings placed obliquely, or crossing each other (Osthaus et al., 2005); and a string-pulling experiment with vertically hanging ropes gave more positive results than the usual horizontal string situation (Hiestand, 2011)—though wolves in the same situation did better than dogs. Treatment for parasites like fleas, heartworms, ticks, and roundworms. London, UK: Routledge and Kegan Paul. Although the comparisons are incomplete, because of the limited range of studies of some of the other relevant species, we conclude that dog cognition is influenced by the membership of all three of these groups, and taking all three groups into account, dog cognition does not look exceptional. However, in general, dogs have been found to do less well in tasks involving invisible displacement of a hidden object, and it is success in these tasks that underpins the claim for Stage 6 performance.

Taking these arguments into account, what would be the appropriate, evolutionarily informative comparison species for the domestic dog?

Tool use, problem-solving, and the display of stereotypic behaviors in the brown bear (Ursus arctos). Surgery is recommended for these dogs, and samples should be collected and submitted for histopathologic evaluation so a definitive diagnosis can be made. Synthesis and evaluation of 64Cu-labeled monomeric and dimeric NGR peptides for MicroPET imaging of CD13 receptor expression Mol Pharm. A., Petelle, M. B., Tennis, M. J., Van der Leeuw, B. K., Stansell, R. T., & Blumstein, D. Social associations between California sea lions influence the use of a novel foraging ground. Although most cognitive work with pigeons has been in the visual domain, there are a few studies of classic problem-solving tasks, such as obstacle removal (Nakajima & Sato, 1993) and using a box to reach an inaccessible object (Cook & Fowler, 2014; Epstein, Kirshnit, Lanza, & Rubin, 1984). 4, 12, 15, 17–19 Histopathologic interpretation of malignant versus benign tissue can be challenging and has resulted in reclassification, disagreement, or histopathologic misdiagnosis in previous studies. Comparing dogs and great apes in their ability to visually track object transpositions. Maes, E., DeFilippo, G., Inkster, A. In what sense are dogs special? Canine cognition in comparative context. And that's not just me being mushy about my guys (even though they are pretty special! Fodor, J. Modularity of mind: An essay on faculty psychology. Can an animal understand what another animal can perceive, and predict what it will understand (perspective taking)? The most obvious of these include the emotional attachments between mother and child, or between romantic partners.

Bräuer, J., & Call, J. Povinelli, D. J., Nelson, K. E., & Boysen, S. T. Comprehension of role reversal in chimpanzees: Evidence of empathy. Hopper, L. M., Lambeth, S. P., Schapiro, S. J., & Whiten, A. The mirror-mark test was first developed for chimpanzees, and although it does not work with every individual, and there has been controversy over its interpretation, the basic result of attention to the affected body part seems to be well established (Gallup et al., 1995; Heyes, 1994). Clayton, N. S., & Dickinson, A. Miklósi and Soproni raise the possibility that the superiority of dogs over chimpanzees arises because the majority of pointing situations are inherently cooperative, and chimpanzees do better in competitive situations. How do our comparison groups fare in tests of object permanence? In this review, we seek to place our enhanced understanding of canine cognition into context. Prognosis for dogs with stage I or II splenic hemangiosarcoma treated by splenectomy alone: 32 cases (1991–1993).

Beyond using another animal as a cue, the next form of social cognition to be considered is the use of another animal as an aid to learning a task—what is generally referred to as social learning, where an observer animal learns a new behavior more quickly as a result of witnessing a demonstrator perform it. In summary, although we have not found as many other cursorial social hunters as we found other carnivorans, from the point of view of a comparative approach to dog cognition, the ecological comparison set looks rather more promising than the phylogenetic one. Muro, C., Escobedo, R., Spector, L., & Coppinger, R. Wolf-pack (Canis lupus) hunting strategies emerge from simple rules in computational simulations. These same kinds of responses have been observed in dogs using a variation of this test. British Journal of Animal Behaviour, 3, 1–25.
Eur J Nucl Med Mol Imaging. However these data suggest that for dogs, it looks like they will sleep better because their owner provides a secure base for them and they feel protected and safe from any real or dream lions. High performance liquid chromatography of carbon-11 labeled thymidine and its major catabolites for clinical PET studies Nucl Med Biol. Kaminski, J., Riedel, J., Call, J., & Tomasello, M. Domestic goats, Capra hircus, follow gaze direction and use social cues in an object choice task. In any case, as with the other senses, our interest is primarily in what animals can do, cognitively speaking, with their visual input. Benson-Amram, S., & Holekamp, K. (2012). We agree with the position of Wrangham (1979) that foraging ecology is fundamental to all social relations, but certainly some aspects of cognition are more easily, and more proximally, predicted from other observable aspects of society. Current Directions in Psychological Science, 25, 357–362.
So, finally, what have the extensive studies of dog cognition of the past two decades brought to comparative cognition in general? The dog performed sufficiently well when the new actions were comparable to the trained ones, such as transporting an object from A to B, but faltered when completely new behaviors were required. Ecology specifies the purposes to which cognition is put in the natural life of an animal, and hence provides the potential motor for cognitive evolution. Nawroth, C., Ebersbach, M., & Von Borell, E. Juvenile domestic pigs (Sus scrofa domestica) use human-given cues in an object choice task. The authors argue that this tendency does not mean that the canids demonstrated a superior understanding of the procedure, but rather that it casts doubt on the extent to which dogs are in fact imitating the actions of human models, rather than using them as a cue. Dogs can teach an important lesson, too, he says.
