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 thenExpand
Roots of a social brain: Developmental models of emerging animacy-detection mechanisms
Here, we review evidence of unlearned predispositions to orient toward visual and auditory cues associated with the presence of animate creatures. We concentrate on studies on chicks of galliformExpand
Inversion of contrast polarity abolishes spontaneous preferences for face-like stimuli in newborn chicks
A spontaneous preference for face-like stimuli has been demonstrated in domestic chicks, similar to that shown by human newborns, suggesting evolutionary continuity across species. Inversion ofExpand
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
Brain asymmetry modulates perception of biological motion in newborn chicks (Gallus gallus)
Few light-points on the joints of a moving animal give the impression of biological motion (BM). Day-old chicks prefer BM to non-BM, suggesting a conserved predisposition to attend to moving animals.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 cerebralExpand
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 suchExpand
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 detailedExpand
