Analyses of intra-individual variations within continuous song sessions revealed that songs consistently cycled through stages of acoustic complexity. At time scales spanning tens of minutes, cyclical variations likely reflected the diving behavior of singers. Changes over shorter time frames suggest that singing humpback whales may also systematically modulate the acoustic complexity of individual sounds during song production, both by gradually morphing units and by varying the number of times they repeat sound patterns. Comparable cycles were evident across years and populations. Cyclical variations within song sessions can reveal how much time and energy singers spend producing tonal versus frequency-modulated/broadband elements. Tonal components are generally more difficult to localize spatially but easier to detect over long distances, suggesting that singing humpback whales may dynamically vary sound production in ways that affect both sound transmission and auditory spatial processing.

While many consider overimitation a uniquely human mechanism, some scholars have hypothesized that domestic dogs may overimitate because of their shared evolutionary history and pedagogical learning structures with humans. Previous literature has presented conflicting evidence regarding the presence of overimitation in domestic dogs. This study expanded upon work by Johnston et al. (2017) and directly compared 3- to 5-year-old children and domestic dogs on the same overimitation task. For both dogs and children, we demonstrated an irrelevant action followed by a relevant action and examined how often subjects reproduced this sequence across four trials. Consistent with an overimitation pattern, children reproduced the irrelevant then relevant sequence at a constant rate across four trials. However, dogs decreased the rate with which they reproduced this sequence across trials-a change which is consistent with a copy-all refine-later strategy or simple exploration. These findings support those in Johnston et al.'s (2017) study and further support the hypothesis that dogs do not overimitate like children.

Here, we addressed a gap in the literature on how OT impacts the learning process in a purely behavioral study. We conducted a 2 (OT, placebo) × 2 (demonstration, no demonstration) study in which dogs received 35 IU intranasal OT spray and demonstrations of how to solve a food puzzle. We tested subjects' levels of engagement with the puzzle as well as with three social partners-the experimenter, the helper, and the owner-both while the dogs were being introduced to the puzzle and while the dogs were allowed to engage with the puzzle. During the puzzle introduction, dogs that received a demonstration increased their gaze toward puzzle and experimenter, and decreased gaze toward their owner as compared to dogs that did not receive a demonstration. When allowed to engage with the puzzle, dogs that received a demonstration gazed more at the experimenter and opened more drawers compared to those receiving no demonstration, although the difference in their general puzzle interaction only trended toward significant. Moreover, more female than male dogs gazed at the experimenter during puzzle engagement, and there was a strong trend for more male than female dogs to solve the puzzle. Finally, results showed only a modest effect of OT on social partner-directed behaviors, including a possible sex-specific effect, and no impact of OT on social learning. The difficulty of the puzzle, identity of the social partner, and dogs' perceptions of the puzzle opening demonstration are discussed as possible contributing factors.

Subsequent relationship dynamics provide a foundation for the evolution of societal norms and associated encephalization in social taxa, like primates and dolphins. Some cultures within these families benefit from interactions with other mammal species but accounts of any wild animals attempting to provision humans are extremely rare. In this article, we present 34 cases of both sexes and all age classes of killer whales (Orcinus orca) offering prey and other items to people who were on boats (n = 21), in the water (n = 11), and on shore (n = 2) in four oceans. A total of 18 species were offered-six fishes, five mammals, three invertebrates, two birds, one reptile, and one seaweed. In almost every case the whales awaited a human response before subsequently reacting. The occurrence of these events suggests a limited cost to exploratory behaviors in some populations of this species. We suggest these apparently nonrandom cases may be representative of interspecific generalized altruism. This behavior may represent some of the first accounts of any wild predator intentionally using prey and other items to directly explore human behavior and thus may highlight the evolutionary convergence of intellect between highest order primates and dolphins.

It is still unknown, however, whether the auditory environment can influence canine affect. This study therefore explored the influence of auditory stimulation on the short-term mood of dogs. Forty-five pet dogs were randomly assigned to one of the three conditions of auditory stimulation (a control of silence, classical music, or audiobook). While being exposed to the auditory stimulus relevant to their condition, each subject animal participated in a commonly employed cognitive bias test, during which their latency to approach a bowl placed in one of the three ambiguous positions was recorded. All dogs were successfully trained, with intact animals taking fewer sessions to reach criterion than neutered subjects. As expected, dogs became increasingly slower to reach the bowl the further it was positioned from the positive location. The animals' latency to reach the bowl placed in the ambiguous positions did not differ significantly between auditory conditions. The study suggests that canine affect is not influenced by the auditory environment, at least in the short term. Methodological issues, both in relation to the protocol adopted in the present investigation and the cognitive bias test more generally, are considered.

Two recurring points of discussion in the literature are the methodological value of Morgan's Canon and the distinction between associative and cognitive processes. Although the existing literature regularly makes claims about the beliefs and attitudes of comparative psychologists, there are few empirical studies verifying these claims. This article fills this gap by presenting and analyzing the views of over 200 comparative psychologists on Morgan's Canon and the associative-cognitive distinction. We found that while there is some agreement between the claims in the existing literature and the views of the practitioners surveyed here (e.g., that Morgan's Canon is a parsimony principle), there are also surprising points of divergence (e.g., practitioners do not view the associative-cognitive distinction as a version of Morgan's Canon). We intend for this study to inform existing philosophical and theoretical work on perennial questions regarding how to study animal minds and behavior.
