| summary | To what extent filial responses are the outcome of spontaneous (unlearned) or acquired preferences? The case of domestic chicks illustrates the connection between predisposed and learned knowledge in early social responses. In the absence of specific experience, chicks prefer to approach objects that are more similar to natural social partners (e.g. they prefer biological vs. rigid motion, face-like arranged vs. scrambled arranged patterns; self-propelled vs. non self-propelled stimuli). Unlearned preferences are complemented by filial imprinting, a powerful learning mechanism that enables chicks to quickly learn the features of specific social partners by mere exposure. After being exposed to visual and acoustic stimuli for a few hours, chicks develop a strong attachment for the specific stimuli they have experienced. While the neural substrates of unlearned and learned preferences are at least partially distinct in chicks, recent evidence shows that spontaneous preferences might orient and facilitate imprinting on animate stimuli, such as the mother hen. Unlearned preferences towards animate stimuli are observed in human neonates as well, and research on precocial species, such as the domestic chick, can inform and guide human infant research with regards to both typical and atypical development. |
