A particularly delightful one comes from Lloyd Morgan himself. In Animal Behavior, which was published after An Introduction to Comparative Psychology (which contains Morgan's Canon), he marvels at a digger wasp that picks up a small pebble in her mandibles and uses it as a hammer to pound and tamp the earth sealing her burrow. what does the Canon mean to the scientists who use it today? A recent article in this issue by Voudouris et al. (2025) gives us a first empirical insight. Using systematic surveys, they shed light on what comparative cognition researchers actually think about Morgan's Canon, the associative-cognitive distinction, and the role of parsimony in interpreting animal behavior. Morgan's Canon began as a plea for rigor. Over time, it became a slogan, sometimes a straitjacket, occasionally a scapegoat. But it remains also a guardrail, a guide, and a goad: it guards against overreach, guides control design and interpretation, and goads us to spell out mechanisms. The new survey shows that researchers still value the Canon but use it with more flexibility and less dogmatism than in the past.

In this study, we focused on the American robin (Turdus migratorius), a species that lays large, elongated, and immaculate blue eggs and is well studied for its robust rejection of smaller, rounder, white, and maculated eggs laid by the brood parasitic brown-headed cowbird (Molothrus ater). Employing a randomized multiple simultaneous parasitism paradigm, we experimentally investigated how model egg color, dimensions, and maculation influenced the rejection rates of eight distinct egg types across 28 different pairings of two eggs at a time. First, we assessed whether egg rejection decisions depended on model egg features. Then, for a subset of trials (36%) where one egg was accepted and the other was rejected, we utilized a conjoint design analysis, a methodology borrowed from economics and marketing. Using the conjoint analysis, we showed that white model eggs were 50% more likely to be rejected relative to blue eggs, small-round eggs were 39% more likely to be rejected compared to large-elongated model eggs, and maculated eggs were 19% more likely to be rejected compared to immaculate eggs. These findings reaffirmed the roles of egg color, dimension, and maculation as key visual cues influencing egg rejection behavior in American robins. These findings also offer methodological advancements to study egg rejection behavior and lend themselves to future comparisons of human and nonhuman decision-making processes.

In our study, we explored the personality of 27 pairs of captive coppery titi monkeys (Plecturocebus cupreus), using a Hominoid Personality Questionnaire of 54 personality items. We also examined the effect of pair duration, pair affiliation, and the presence of offspring on the personality of these pairs. We built a model with five components to describe titi monkey personality structure in our colony and labeled these components as aggressive, cool, cautious, innovative, and helpful. Helpful, which we relate to \"agreeableness,\" was significantly higher in males than in females. Aggressive and helpful were correlated within couples. Helpful was also negatively related to the time spent since pairing. Innovative was higher for pairs with higher affiliation. Additionally, we compared personality similarity between a group of pairs that were created based on initial compatibility (determined via a \"speed-dating\" experiment), and a group of tenure-matched pairs that were determined quasirandomly. Pairs determined from speed dating were more helpful than pairs from the colony comparison group, which suggests that high levels of initial attraction may facilitate an increase in prosocial personality traits. Our findings, including the negative correlation of \"helpful\" with time since pairing and the heightened \"innovative\" trait in pairs with stronger affiliation, may suggest subtle dynamics within titi monkey personalities. These insights contribute to a broader understanding of nonhuman primate personalities.

Chimpanzees exhibit evidence of social negotiation through manual gesturing to achieve imperative goals. Chimpanzee social negotiations are influenced by demographic factors like age, sex, social rank, and identity, as well as communicative properties such as gesture type, gesture modality, gesture position, and context. In our study, we build on prior research by analyzing how chimpanzees use facial signals during social negotiations. We used machine learning models and sequential pattern analysis to analyze the combined effects of facial signals and manual gesturing properties, along with demographic factors. Our analyses revealed that facial signals and manual gesturing are important for predicting the success of chimpanzee social negotiations. We also found that clear communication (using distinct facial signals and manual gestures in each context) is important for navigating social negotiations, much like is true for humans.

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.

However, the role of olfaction and vision in dogs' perception of everyday situations has been underexplored. To investigate this topic, we used a simple food-searching paradigm. A treat was hidden in one of three locations, either (a) visible from the starting point (vision condition), (b) invisible from the starting point (smell condition), or (c) invisible with an additional decoy treat presented as a distraction (fake condition). About 87 dogs of various breeds were categorized into either the olfactory-focused or the vision-focused group based on their sniffing behavior in a pretest. It was hypothesized that olfactory-focused dogs would preferentially use their sense of smell for task solving, whereas vision-focused dogs would rely more on visual information. Thus, it was expected that dogs of each group would have an advantage in the corresponding condition. However, there was no difference between groups in the duration to find the food in the three conditions. In general, food was approached faster in the vision condition, and dogs in all groups were distracted by the presence of the fake food. Thus, for all dogs, the visual sense was more dominant than the olfactory sense, and they could easily switch between using the two senses. The results are discussed in light of breed differences and general perception skills of domestic dogs.

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).

Such sensitivity to others' skill deficits is expected to be rare, but may be found in species with high prosociality and other-regarding preferences, such as cooperative breeders. Here, we compared the food-sharing patterns of cooperatively breeding common marmosets (Callithrix jacchus) and closely related but independently breeding squirrel monkeys (Saimiri boliviensis) under two conditions. In the baseline condition, food was easily accessible whereas in the experimental condition, individuals had to solve a puzzle to access the food. We found that the cooperatively breeding marmosets, but not the independently breeding squirrel monkeys, shared more when immatures lacked the skill to obtain the food from the apparatuses. Skill sensitivity might be associated with the presence of other-regarding preferences and a strong proclivity to proactively share food during baseline conditions. This proclivity has evolved in marmosets, but not squirrel monkeys, in the context of cooperative breeding and may facilitate the emergence of skill recognition, information donation, and teaching.

Several species hunt mobile prey, placing demands on working memory and selecting for sociocognitive abilities such as predicting prey behavior. The mechanisms by which apes overcome foraging and hunting challenges are difficult to elucidate. Field investigations provide rich data sets but lack experimental control, limiting the gamut of questions they can answer, while experiments with captive subjects offer lower generalizability to real-world situations. Virtual environments (VEs) present a compromise, combining experimental specificity with proxies of realistic situations. In this study, chimpanzees and bonobos moved through a three-dimensional VE using a touchscreen. All subjects learned to chase and catch moving rabbits, some exhibiting high success rates even in the presence of large obstacles. Success in trials with a first-person (FP) viewpoint was much higher than in trials presented from overhead, suggesting that the immersive nature of FP trials helped subjects to understand their location in the environment better than when they took a top-down view. Data were analyzed using generative computational agent models, identifying that subjects occasionally employed anticipatory hunting strategies, but more often used a direct chasing strategy. This study validates the use of VEs as an experimental paradigm, demonstrating that apes can understand the behavior of moving agents in situations of varying complexity and that computational modeling can be utilized to delve into behavioral data at a fine-grained level and identify which of several cognitive strategies they fit best.
