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…

It is reported that newly hatched, visually naïve domestic chicks presented with objects exhibiting motion either self-produced or caused by physical contact prefer to associate with self-propelled objects, which supports the idea of an evolutionarily ancient, predisposed neural mechanism in the vertebrate brain for the detection of animacy.

It is shown that there is a tendency for right brain hemisphere dominance when performing social cognitive actions in the domestic chick, which has effects on the chick's perception towards and interaction with its environment.

The hypothesis that the human system possesses an early available, possibly innate basic mechanism to compute causality, such a mechanism being sensitive to the additive effect of certain well-defined spatiotemporal cues present in the causal event independently of any prior visual experience is supported.
Symmetry perception by poultry chicks and its implications for three-dimensional object recognition

Evidence that young poultry chicks readily generalize bilateral symmetry as a feature of two-dimensional patterns in fronto-parallel view is given and evidence that chicks trained to distinguish symmetrical from asymmetrical patterns treat rotated views of symmetrical ‘ objects’ as symmetrical is given.
Mom’s shadow: structure-from-motion in newly hatched chicks as revealed by an imprinting procedure
The present data shows that similar general mechanisms underlying the perception of structure-from-motion and the extraction of 3-D information are shared by humans and animals and occur similarly in birds as known for mammals; this possibly indicates a common phylogenetic origin of these processes.
Animal visual perception.
Experimental data presented here will lead to the conclusion that a number of basic perceptual principles of organization and functioning are shared between species.

It is shown that declarative-like memory of integrated information is available at early stages of development, and it is associated with a left hemisphere dominance.
