Performance of Pugs, German Shepherds, and Greyhounds (Canis lupus familiaris) on an odor-discrimination task.
Public opinion and the scientific literature alike reflect a widespread assumption that there are differences in behavior between dog breeds. Direct empirical behavioral assessments of such differences, however, are rare and have produced mixed results. One area where breed differences are often assumed is olfaction, where German Shepherds, hounds, and Labradors are commonly used for odor-detec...
متن کاملIncentive contrast in domestic dogs (Canis familiaris).
Dogs (Canis familiaris) trained to receive a preferred food (dry beef liver) from an experimenter learned to maintain a longer gaze on the experimenter than dogs receiving a less preferred food (dog pellets). Dogs downshifted from dry liver to pellets rejected food more frequently than nonshifted controls. Gaze duration also decreased in downshifted dogs below the level of a group always reinfo...
متن کاملDo dogs (Canis familiaris) understand invisible displacement?
Domestic dogs (Canis familiaris) perform above chance on invisible displacement tasks despite showing few other signs of possessing the necessary representational abilities. Four experiments investigated how dogs find an object that has been hidden in 1 of 3 opaque boxes. Dogs passed the task under a variety of control conditions, but only if the device used to displace the object ended up adja...
متن کاملComprehension of human communicative signs in pet dogs (Canis familiaris).
On the basis of a study by D. J. Povinelli, D. T. Bierschwale, and C. G. Cech (1999), the performance of family dogs (Canis familiaris) was examined in a 2-way food choice task in which 4 types of directional cues were given by the experimenter: pointing and gazing, head-nodding ("at target"), head turning above the correct container ("above target"), and glancing only ("eyes only"). The result...
متن کاملLandmark-based search memory in the domestic dog (Canis familiaris).
Recent studies have suggested that any animal that relies on landmark-based search memory encodes and uses metric properties of space to navigate. So far, however, metric information provided by landmarks has been predominantly investigated in avian species. In the present study, I investigated whether the domestic dog (Canis familiaris), a mammalian species, encodes the distance and direction ...
