Set-forming and set-shifting were studied in children of three age groups: five to six-, six to seven- and nine to ten-year-old. Set effect displayed itself in contrast illusions in most of the subjects (69 of 73). Age differences in set plasticity and in reaction time to a probe stimulus were revealed. Five to six-year-old children formed a more rigid set than older ones. According to EEG coherence function in theta- and alpha-bands and behavioral data, a hypothesis of two systems being involved in set-forming and set-shifting is proposed. These systems are: a fronto-talamic system of selective attention, and a system of cortico-hippocampal connections that are involved in cortical processing of novel visual information and in episodic memory. The age of 6-7 years is shown to be critical in forming a plastic type of cognitive set.
5至6岁、6至7岁和9至10岁。在大多数受试者（73名中的69名）中，集合效应表现为对比错觉。揭示了集合可塑性和对探测刺激的反应时间的年龄差异。5至6岁的儿童形成的集合比年龄较大的儿童更僵化。根据θ波和α波频段的脑电图相干函数以及行为数据，提出了两个系统参与集合形成和集合转换的假设。这两个系统是：选择性注意的额丘脑系统，以及参与新视觉信息的皮质处理和情景记忆的皮质-海马连接系统。结果表明，6至7岁是形成可塑性认知集合的关键年龄。
