Numerical Abstraction in Young Domestic Chicks (Gallus gallus)
In a variety of circumstances animals can represent numerical values per se, although it is unclear how salient numbers are relative to non-numerical properties. The question is then: are numbers intrinsically distinguished or are they processed as a last resort only when no other properties differentiate stimuli? The last resort hypothesis is supported by findings pertaining to animal studies ...
متن کاملRatio abstraction over discrete magnitudes by newly hatched domestic chicks (Gallus gallus)
A large body of literature shows that non-human animals master a variety of numerical tasks, but studies involving proportional discrimination are sparse and primarily done with mature animals. Here we trained 4-day-old domestic chicks (Gallus gallus) to respond to stimuli depicting multiple examples of the proportion 4:1 when compared with the proportion 2:1. Stimuli were composed of green and...
متن کاملLateralization of social cognition in the domestic chicken (Gallus gallus).
In this paper, we report on the ongoing work in our laboratories on the effect of lateralization produced by light exposure in the egg on social cognition in the domestic chick (Gallus gallus). The domestic chick possesses a lateralized visual system. This has effects on the chick's perception towards and interaction with its environment. This includes its ability to live successfully within a ...
متن کاملThe magnetic compass of domestic chickens, Gallus gallus.
By directional training, young domestic chickens have been shown to use a magnetic compass; the same method has now been used to analyse the functional characteristics and the physical principles underlying the chickens' magnetic compass. Tests in magnetic fields with different intensities revealed a functional window around the intensity of the local geomagnetic field, with this window extendi...
متن کاملOntogenesis of Intestinal Nutrient Transport in Domestic Chickens (gallus Gallus) and Its Relation to Growth
THE FACTORS that determine growth rates among birds have provoked interest for decades. As a group, birds include the fastestgrowing vertebrates (Case 1978); yet, birds exhibit an impressive array of species-specific growth rates that vary with adult body size, degree of precociality, and ecology (Lack 1968, Ricklefs 1968, 1976, 1983). Because mortality is high in vulnerable young birds, many a...
