Previous studies have reported that they can discriminate the shape, size, thickness, and even material of objects through echolocation. However, little is known about the discrimination of quantities other than size and thickness (e.g., the number of objects). It is also unclear whether Weber's law (i.e., ratio dependency) holds for quantity discrimination through echolocation. In this study, we examined relative quantity judgments of visually occluded objects presented underwater by bottlenose dolphins. We found that they could discriminate pairs of same-sized objects ranging from one to eight, with performance improving as the difference ratio between the two numbers increased. In addition, their performance also improved as the magnitude of the number of objects involved increased. An additional test revealed that the accuracy of discrimination through echolocation was comparable to that of visual relative quantity judgments of the objects presented above water. On the other hand, under the condition that the overall size of each object (i.e., the sum of areas) was incongruent with the number of objects, performance was lower than when number and size were covarying. However, even within the incongruent condition, the effect of the number ratio was still observed, suggesting that the dolphins might have used various types of quantity information, such as number and size, flexibly to solve the task.

They should be both sensitive to variation in the target odors and specific enough to avoid false alerts, but how readily they achieve this is likely to depend on the training method employed. The majority of agencies train by presenting single target odors in isolation, and adding additional odors consecutively, although recent research with rats suggests intermixing the target odors concurrently throughout training may be a more effective approach. This study therefore tested the relative efficacy of intermixed training in dogs. Using an odor-detection lineup, pet dogs were trained to detect two target odors, A and B. Those allocated to the \"sequential\" group were trained to criterion on odor A and then trained on odor B (or vice versa), the \"compound\" group were trained on a mixture of AB, and the \"intermixed\" group trained on A and B concurrently. Each dog was then tested on all combinations of the test stimuli (A, B, and AB), as well as combinations containing a novel interferent (AC, BC, and ABC). Results revealed that dogs trained by the intermixed method made significantly more correct (true positive) indications, and significantly fewer miss (false negative) indications than the other two methods, suggesting that intermixed training is more effective than currently used alternative training methods. Thus, for improved performance and generalization, we recommend detection dog training should use an intermixed method of training.

This may include gathering and integrating information through multiple modalities. Using a cross-modal preferential-looking paradigm, we investigated whether dogs possess a cross-modal mental representation of conspecific age classes. In Experiment 1, dogs were presented with images of an adult dog and a puppy projected side by side on a wall while a vocalization of either an adult dog or a puppy was played back simultaneously. To test the effect of relative body size between adult dog and puppy images, two size conditions (natural size and same size) were employed for visual stimuli. We examined dogs' looking behavior in response to cross-modally matched versus mismatched stimuli. We predicted that if dogs have cross-modal representations of age classes, they would exhibit prolonged attention toward matched images compared to mismatched ones. In Experiment 2, we administered the same paradigm within an eye-tracking experiment to further improve the measurement quality of dogs' looking times. However, dogs' looking times in either experiment did not demonstrate significant differences based on the match or mismatch between image and vocalization. Instead, we observed a size effect, indicating dogs' increased attention toward larger adult dog images compared to smaller puppy images. Consequently, we found no evidence of cross-modal representation of age class in dogs. Nonetheless, we found increased looking time and pupil size upon hearing puppy vocalizations compared to adult vocalizations in Experiment 2, suggesting that dogs exhibited heightened arousal when hearing puppy whining.

In particular, the members of the cockatoo family are left-footed for food-holding at proportions reminiscent of right-handedness in humans. Here, we examine the limb lateralization of the Goffin's cockatoo (Cacatua goffiniana), a tool-using and technically proficient species used as a model of parrot cognition. First, we investigated the postural origins theory, originally proposed in primates to explain handedness. According to this theory, the hand that was used by ancestral primates to cling to trees developed finer motor control. Using a series of problem-solving tasks, we tested the possibility that the parrot's postural foot, which is similarly used to grasp tree branches, could be more motorically skilled. Although we did not find support for this idea, we did discover that task type does affect foot use, as subjects switched from using their food-holding dominant foot to their other foot during reaching tasks. We also found that the cockatoos more flexibly switched and used both feet when faced with more challenging tasks. Secondly, we attempted a partial replication of a previous study with parrots derived from the enhanced cognition hypothesis, which claimed that more lateralized individuals were better problem solvers. However, we did not find this relationship to be significant in any of our tasks. We did confirm that individual Goffin's cockatoos are extremely limb lateralized for food-holding in addition to other tasks, which may play a role in their approaches to problem-solving.

This knowledge can aid in how we understand the foraging strategies of many animals, particularly understudied and endangered species, such as the Guatemalan beaded lizard (Heloderma charlesbogerti). These actively foraging lizards rely on chemoreception to locate prey, but it is unknown to what extent they engage in olfaction and vomerolfaction to hunt and navigate their environment. We investigated how Guatemalan beaded lizards moved through a physical maze. When navigating an eight-arm radial maze with all arms baited, lizards tended to turn into the immediately adjacent arm in a single direction, similar to other reptiles that have been tested in radial arm mazes. In a T-maze, the lizards had to discriminate between arms that contained scent and no-scent from a distance. They were generally unable to choose the baited (correct) arm at levels greater than chance, indicating an inability for this discrimination. With the addition of a scent trail, however, all lizards chose the baited arm at levels significantly above chance, and this increased accuracy was correlated with increased latency to make the arm choice. The lizards also demonstrated a decreased rate of tongue flicking as proximity to reward increased. Guatemalan beaded lizards can efficiently navigate a radial arm maze and can successfully use vomerolfaction with substrate-borne cues to locate prey, but they appear to have minimal olfaction abilities when sensing from a distance.

That is to say, without the presence of words, eye contact, or facial expressions, dogs followed a misguiding cue and chose a smaller reward that a stranger had deemed more valuable than a larger one.

According to standard learning and optimal foraging theories, it should not exist. Thus, any evidence of such behavior is noteworthy. We briefly review the recently introduced play hypothesis, which proposes that contrafreeloading is more likely if the action involved is viewed as play rather than work (i.e., agreeable rather than aversive). One might consequently expect species that are relatively more playful to be more likely to engage in contrafreeloading. We evaluated this possibility by testing purportedly playful umbrella cockatoos (Cacatua alba); we studied four residents of a bird sanctuary in upstate New York (Dudley, JJ, Poly, and Teddy Bear). The task involved choosing between shelled and deshelled almonds; the former choice constituting evidence of contrafreeloading. We documented contrafreeloading in a novel species and then compared our results with previously published data on the reportedly less playful Grey parrots (Psittacus erithacus). Individually, a higher percentage of cockatoos engaged in contrafreeloading on more than half the trials than did the Greys, with statistically similar levels of individual variation, but the overall amount of contrafreeloading was not statistically significantly different between the species at a group level. We discuss possible reasons for these findings. Additionally, we examine similarities in the behavioral expression of play and contrafreeloading.
