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… Expand

Chicks discriminate human gaze with their right hemisphere
Domestic chicks were tested for eye use while feeding on the floor in the presence of a dummy mask which could either look at the location where the chicks were feeding or in the opposite direction.… Expand

Lateralization of social learning in the domestic chick, Gallus gallus domesticus: learning to avoid
Social learning occurs through the observation of conspecifics performing biologically relevant behaviours. Like other forms of learning, aptitude for such tasks may be influenced by cerebral… Expand

Time-dependent lateralization of social learning in the domestic chick (Gallus gallus domesticus): Effects of retention delays in the observed lateralization pattern
Day-old chicks have been shown capable of learning to avoid pecking by observation only of a conspecific showing a disgust reaction after pecking a bitter-tasting bead. This learning is lateralized:… Expand

Advantages of a Lateralised Brain for Reasoning About the Social World in Chicks
Social animals require sophisticated cognitive abilities to recognise other individuals and to deduce hierarchies on the basis of observed interactions among them. The domestic chicken is one such… Expand

Structural Imbalance Promotes Behavior Analogous to Aesthetic Preference in Domestic Chicks
Background Visual images may be judged ‘aesthetic’ when their positioning appears imbalanced. An apparent imbalance may signify an as yet incomplete action or event requiring more detailed… Expand

STRUCTURAL IMBALANCE AND AESTHETIC PREFERENCE IN DOMESTIC CHICKS
In Arnheim's (1954/1974) theory of structural balance, an image is more aesthetically pleasing when it demonstrates balance between multiple internal sources of directed perceptual force. Areas of… Expand
Social cognition and learning mechanisms: Experimental evidence in domestic chicks
In this paper we review the literature on social learning mechanisms in the domestic chick, focusing largely on work from our own laboratories. The domestic chicken is a social-living bird that… Expand

Lateralised Social Learning in Chicks
In social learning, one individual acquires information on objects encountered in the environment by observing the interaction of another individual with such objects. A highly adaptive form of… Expand
