Colour vision of domestic chicks.
The colour vision of domestic chicks (Gallus gallus) was investigated by training them to small food containers decorated with tilings of grey and coloured rectangles. Chicks learn to recognise the colour quickly and accurately. Chicks have four types of single-cone photoreceptor sensitive to ultraviolet, short-, medium- or long-wavelength light. To establish how these receptors are used for co...
متن کاملDomestic chicks perceive stereokinetic illusions.
Stereokinetic illusions occur when certain 2-D patterns are set in slow rotation in a plane perpendicular to the line of sight. Such phenomena have never been investigated in animal species other than our own. We used the domestic chick (Gallus gallus) to check whether these illusions are experienced by non-human species, taking advantage of filial imprinting. Newly hatched visually naive chick...
متن کاملColour categorization by domestic chicks.
Spectral stimuli form a physical continuum, which humans divide into discrete non-overlapping regions or categories that are designated by colour names. Little is known about whether non-verbal animals form categories on stimulus continua, but work in psychology and artificial intelligence provides models for stimulus generalization and categorization. We compare predictions of such models to t...
متن کاملThe effects of early post-hatching changes of imprinting object on the pattern of monocular/unihemispheric sleep of domestic chicks.
The pattern of monocular/unihemispheric sleep (Mo-Un sleep) was studied behaviourally in male and female chicks after early post-hatching changes of the imprinting object. Chicks were reared with an imprinting object on day 1 post-hatching which was removed or changed on day 2. On day 1, time spent in binocular sleep (both eyes closed) was similar in male and female chicks, though the number of...
متن کاملEffect of Milk Thistle (Silybum marianum L.) on Biochemical Parameters and Immunity of Broiler Chicks Fed Aflatoxin B1 after Three Weeks
Background: This study was conducted to determine the efficacy of milk thistle seeds (MTSs) in counteracting the toxic effects of aflatoxin B1 (AFB1) in a contaminated diet fed to broilers.Methods: Two dietary inclusion rates of AFB1 (0, 0.250 and 500 ppb) and MTS (0, 0.5 and 1%) were tested in a 3×3 factorial manner. The effect of nine experimental treatments was assessed using 216 one-d-old R...
