Le Rôle de l'expérience sur la sémantique du cri d'offrande alimentaire chez le poussin

Abstract : In contrast to the effect of clucking the vocal component of tidbitting exerts no initial attraction on naive chicks wheter it occurs in its juvenile or its maternal form. From the moment that the first chicks free themselves of their shells maternal tidbitting increases in frequency up to a rate of 25 series an hour. When visually perceived, the movements associated with the tid-bit call: movement of the mother's beak while pecking and the dropping of small fragments of food releases in neonate an approach response pecking and occasionnally swallowing. On the other hand, the response to the tid bit call alone by chick nestling under a hen only occur if they have had several hours of active experience previously. The delay is not due to maturation with age, since the same duration of prior experience is necessary in chicks removed from the mother at hatching and returned to her at one, two or even three days. This seems to show that the attractive value of the vocal signal originally neutral or at most capable of inducing a certain state of arousal is individually acquired by conditioning when associated to an attractive movement signal and reinforced by pecking and food intake.
