Aim Studies have reported conflicting findings on whether different smells can reduce distress when infants undergo painful procedures. Our study assessed the impact of vanilla on infants' responses to a painful toe lance, including possible gender d

and Summary To assess the influence of “littermate” characteristics on early social interactions, preweaning spiny mice (Acomys cahirinus) were raised in pairs consisting of pups differing in age by 15 days, or with a Mus musculus agemate. Wherea

Aim: To assess the effects of exposure to the odour of mother's milk on breastfeeding behaviour of premature neonates. Methods: Thirteen preterm infants born at 30–33 weeks gestational age were tested. Seven infants were randomly assigned to the mi

About 1-2% of the human genome is allocated to production of receptors for the olfactory epithelium--a hint as to the possible importance of this chemical sense, which includes two anatomically distinct systems: the main olfactory system with sensory

Young domestic fowl chicks, Gallus gallus domesticus, discriminate between familiar and unfamiliar agemates. We investigated the retention of individual discrimination and the effects of social experience on such recognition memory. In the first seri

SUMMARY Most ungulates are gregarious species and outside the mating season are typically observed in single-sex groups. However little is known about the mechanisms underlying social segregation between sexes. We investigated the effect of conspecif

We assessed the influence of mother ewes (Ovis aries) on the development of their lambs’ discriminative social interactions. Experiment 1: twin lambs in one condition were housed with their mother in small groups (M lambs), while twins in a second

The role of visual cues in individual agemate discrimination by lambs (Ovis aries) was assessed in two experiments. Lambs in the initial experiment were tested in pairs in a dark room, thereby eliminating access to the partners' visual phenotypes. Wh

Familiarization with individuals resulting from direct exposure is the primary mechanism mediating social recognition in many vertebrates. However, discernible phenotypic similarity among close kin may provide an additional basis for recognizing prev
