Neural and behavioural analyses have shown that the formation of filial preferences in young, precocial birds involves at least two separate processes. One process is an emerging predisposition to approach stimuli with the characteristics of the natural mother. The other (learning) process of filial imprinting results in chicks preferentially-approaching a stimulus to which they have been exposed and involves forming links between the components of the exposed stimulus. The neural substrate for the predisposition is different from that underlying imprinting, and different regions of the chick brain are involved in distinct aspects of learning about imprinting stimuli.
神经学和行为学分析表明，早成性幼鸟中亲子偏好的形成至少涉及两个独立的过程。一个过程是出现接近具有自然母亲特征刺激的倾向。亲子印记的另一个（学习）过程导致雏鸟优先接近它们接触过的刺激，并涉及在接触刺激的各个组成部分之间建立联系。这种倾向的神经基础与印记的神经基础不同，雏鸟大脑的不同区域参与了关于印记刺激学习的不同方面。
