内隐统计学习（ISL）允许学习环境模式，并被认为是重要的感知，认知和语言发展的许多方面。然而，很少有人知道的发展背后的神经机制，支持ISL。为了探索ISL的神经发育，我们使用一种新的预测-靶范式研究了成人、年龄较大的儿童（9 - 12岁）和年龄较小的儿童（6 - 9岁）的学习的事件相关电位（ERP）相关性。在这项任务中，这是一个标准的oddball范式的修改，参与者被指示查看视觉刺激的串行输入流，并与一个按钮按下时，一个特定的目标出现的反应。参与者不知道的是，隐藏的统计概率嵌入在任务中，使得目标在不同程度上被不同的预测刺激所预测。结果是相似的，在所有三个年龄组：P300的组成部分，引起的高预测刺激后，充分暴露于统计概率。这些神经生理学研究结果为ISL的发育不变性提供了证据，至少在6岁时达到成人样能力。
Implicit statistical learning (ISL) allows for the learning of environmental patterns and is thought to be important for many aspects of perception, cognition, and language development. However, very little is known about the development of the underlying neural mechanisms that support ISL. To explore the neurodevelopment of ISL, we investigated the event-related potential (ERP) correlates of learning in adults, older children (aged 9-12), and younger children (aged 6-9) using a novel predictor-target paradigm. In this task, which was a modification of the standard oddball paradigm, participants were instructed to view a serial input stream of visual stimuli and to respond with a button press when a particular target appeared. Unbeknownst to the participants, covert statistical probabilities were embedded in the task such that the target was predicted to varying degrees by different predictor stimuli. The results were similar across all three age groups: a P300 component that was elicited by the high predictor stimulus after sufficient exposure to the statistical probabilities. These neurophysiological findings provide evidence for developmental invariance in ISL, with adult-like competence reached by at least age 6.
