A predisposition for biological motion in the newborn baby
Data support the hypothesis that detection of biological motion is an intrinsic capacity of the visual system, which is presumably part of an evolutionarily ancient and nonspecies-specific system predisposing animals to preferentially attend to other animals.
Cerebral and behavioural assymetries in animal social recognition
Evidence is here summarized that animal species belonging to distant taxa show forms of social recognition, a sophisticated cognitive ability adaptive in most social interactions. The paper then
Visually Inexperienced Chicks Exhibit Spontaneous Preference for Biological Motion Patterns
It is reported that newly hatched chicks, reared and hatched in darkness, at their first exposure to point-light animation sequences, exhibit a spontaneous preference to approach biological motion patterns, and this predisposition extends to the pattern of motion of other vertebrates, even to that of a potential predator such as a cat.
Selective attention to humans in companion dogs, Canis familiaris
Integration into human societies requires dogs to express adaptable social attitudes, involving high levels of attention to other individuals. In the present study, we developed a new behavioural
Lateralized righting behavior in the tortoise (Testudo hermanni)
This work investigated the presence of motor asymmetries in the tortoise Testudo hermanni using the righting response, a procedure already employed to assess behavioural lateralization in amphibians, and found a bias at the individual as well as at the population level for preferentially turning on the right side.
Number-space mapping in the newborn chick resembles humans’ mental number line
3-day-old chicks share this representation of numbers, consistently seeking lowerNumbers to the left of a target and larger numbers to the right (see the Perspective by Brugger).
Perception of partly occluded objects by young chicks
The first demonstration of recognition of partly occluded objects in a bird species, the domestic chickGallus gallus, is provided, using the naturalistic setting made available by filial imprinting, a process whereby young birds form attachments to their mothers or some artificial substitute.
