Article Correctness Is Author's Responsibility: Local interaction rules and collective motion in black neon tetra (<em>Hyphessobrycon herbertaxelrodi</em>) and zebrafish (<em>Danio rerio</em>).

We explored the local motion rules used by interacting individuals in small groups of black neon tetra (Hyphessobrycon herbertaxelrodi) and zebrafish (Danio rerio) to ascertain if and how these rules underlie the fishes’ global collective coordinated m…

Article Correctness Is Author's Responsibility: Personality in captive killer whales (<em>Orcinus orca</em>): A rating approach based on the five-factor model.

The comparative study of animal personality has received great interest in recent years. Some studies have analyzed personalities in cetaceans (exclusively in dolphins), but none have analyzed the factorial structure of personality of any species in th…

Article Correctness Is Author's Responsibility: Social learning of goal-directed actions in dogs (<em>Canis familiaris</em>): Imitation or emulation?

A goal-directed action is composed of two main elements on which the observer may focus its attention: the movement performed (i.e., the action) and the outcome (i.e., the goal). In a social learning situation, consequently, the observer may imitate th…

Article Correctness Is Author's Responsibility: Associations among behavioral inhibition and owner-rated attention, hyperactivity/impulsivity, and personality in the domestic dog (<em>Canis familiaris</em>).

In humans, behavioral disinhibition is associated with attention-deficit/hyperactivity disorder (ADHD). Limitations to rodent models of ADHD-like behaviors/symptoms may be augmented by complementary ones, such as the domestic dog. We examined associati…

Article Correctness Is Author's Responsibility: Perception of the Delboeuf illusion by the adult domestic cat (<em>Felis silvestris catus</em>) in comparison with other mammals.

The comparative study of the perception of visual illusions between different species is increasingly recognized as a useful noninvasive tool to better understand visual perception and its underlying mechanisms and evolution. The aim of the present stu…

Article Correctness Is Author's Responsibility: The effects of ambient temperature and lighting intensity on wheel-running behavior in a diurnal rodent, the Nile grass rat (<em>Arvicanthis niloticus</em>).

Environmental conditions, such as the light–dark cycle and temperature, affect the display of circadian rhythmicity and locomotor activity patterns in mammals. Here, we tested the hypothesis that manipulating these environmental conditions would affect…

Article Correctness Is Author's Responsibility: Locomotion and posture development in immature male and female rats (<em>Rattus norvegicus</em>): Comparison of sensory-enriched versus sensory-deprived testing environments.

The aim of the current study was to provide normative data on spontaneous locomotion and posture behavior in developing rats (Rattus norvegicus), during the first 2 postnatal weeks. Male and female rat pups were tested daily from P1 (postnatal day 1; ∼…

Article Correctness Is Author's Responsibility: Object permanence in <em>Giraffa camelopardalis</em>: First steps in giraffes’ physical cognition.

Although behavior, biology, and ecology of giraffes have been widely studied, little is known about their cognition. Giraffes’ feeding ecology and their fission–fusion social dynamics are comparable with those of chimpanzees (Pan troglodytes), suggesti…

Article Correctness Is Author's Responsibility: Like chimpanzees<em> (Pan troglodytes</em>), pigeons (<em>C</em><em>olumba livia domestica</em>) match and Nash equilibrate where humans (<em>H</em><em>omo sapiens</em>) do not.

Martin, Bhui, Bossaerts, Matsuzawa, and Camerer (2014) found that chimpanzee pairs competing in matching-pennies games achieved the Nash equilibrium whereas human pairs did not. They hypothesized this outcome may be due to (a) chimpanzee ecology produc…

Article Correctness Is Author's Responsibility: Freestanding bipedal posture and coordinated bimanual manipulation significantly influence lateralized hand use in rhesus monkeys <em>(Macaca mulatta</em>) and chimpanzees (<em>pan troglodytes</em>).

Investigations of behavioral lateralization in nonhuman primates yield important insights into brain–behavior relationships. In turn, they provide clues about both proximal and distal factors that shape the development and expression of association bet…

Article Correctness Is Author's Responsibility: Deceased-infant carrying in nonhuman anthropoids: Insights from systematic analysis and case studies of bonnet macaques (<em>Macaca radiata</em>) and lion-tailed macaques (<em>Macaca silenus</em>).

Existing models of attachment do not explain how death of offspring affects maternal behavior. Previous descriptions of maternal responsiveness to dead offspring in nonhuman anthropoids have not expounded the wide variation of deceased-infant carrying …
