In this theoretical work, we treat behavioral and perceptual issues on an equal footing and examine the emergence of mutually exclusive behavioral patterns and perceptual variables during infant development from the perspective of multistable competitive dynamic systems. Accordingly, behavioral modes and modes of perception compete with each other for activation. One and only one mode survives the mode-mode competition, which accounts for the incompatibility of modes being considered. However, the winning behavioral or perceptual state is not predefined. Rather, we argue that during particular stages of maturation multiple modes coexist for the same set of developmental, body-scaled, and environmental parameters or constraints. The winning behavioral or perceptual state depends on these parameters as well as on initial conditions as operationalized in terms of previously performed behaviors or utilized perceptual stimuli. We give explicit examples of our approach and address the emergence of two-handed grasping and catching movements and the emergence of monocular and binocular vision during infant development. In particular, we propose that the emergence of midline crossing movements in 3- to 6-month-old infants involves two independent but interaction control parameters: a body-scaled and a developmental one. Likewise, we argue that the onset of binocularity in infants involves two independent but interaction control parameters: a developmental and an environmental one.
在这项理论工作中，我们平等对待行为和感知问题，并从多稳态竞争动力学系统的角度研究婴儿发育过程中相互排斥的行为模式和感知变量的出现。相应地，行为模式和感知模式相互竞争以获得激活。只有一种模式在模式间竞争中存活下来，这解释了所考虑模式的不兼容性。然而，获胜的行为或感知状态并不是预先确定的。相反，我们认为，在特定的成熟阶段，对于相同的一组发育、身体尺度和环境参数或约束条件，多个模式共存。获胜的行为或感知状态取决于这些参数以及初始条件，这些初始条件是根据之前执行的行为或使用的感知刺激来操作的。我们给出了我们方法的明确示例，并讨论了婴儿发育过程中双手抓握和捕捉动作的出现以及单眼和双眼视觉的出现。特别是，我们提出，3 至 6 个月大的婴儿中线交叉运动的出现涉及两个独立但相互作用的控制参数：一个是身体尺度的，一个是发育的。同样，我们认为婴儿双眼视觉的出现涉及两个独立但相互作用的控制参数：一个是发育的，一个是环境的。
