Stable individual differences in separation calls during early development in cats and mice

摘要: Background The development of ethologically meaningful test paradigms in young animals is an essential step the study ontogeny animal personality. Here we explore possibility to integrate offspring separation (distress) calls into consistent individual differences behaviour two species mammals, domestic cat (Felis silvestris catus) and mound-building mouse (Mus spicilegus). Such vocal responses mammals are a potentially useful option as they represent important element mother-offspring communication with strong implications for survival. In addition, neural control vocalisation closely associated emotional state.
