The present study will test two hypotheses in human visual and multisensory neural networks: (1) The development of top-down communication lags behind the development of bottom-up processing; (2) the development of top-down processing depends to a larger extent on early sensory experience than the development of bottom-up processing. Two EEG paradigms, a visual attention and a multisensory paradigm, will be developed in human adults. They will consecutively be adapted to children (5-11 year old, prospective developmental approach) and sight-recovery individuals (retrospective developmental approach) to test these two hypotheses, respectively.

本研究将检验人类视觉和多感觉神经网络的两个假设：（1）自上而下的通信发展滞后于自下而上的处理发展； (2)自上而下加工的发展比自下而上加工的发展更大程度地依赖于早期的感官经验。将在成人中开发两种脑电图范式，即视觉注意范式和多感觉范式。他们将依次适应儿童（5-11岁，前瞻性发展方法）和视力恢复个体（回顾性发展方法），分别检验这两个假设。
