视觉工作记忆(VWM)的容量是指一次可以在头脑中保持的视觉信息的数量,易于为正在进行的任务访问。在健康的年轻人中,VWM的容量极限对应于大约三个简单的对象。虽然一些研究人员认为VWM的能力在生命的早期变得像成年人一样,但其他人声称VWM的能力在童年中期之后继续发展。在这里,我们评估了VWM能力是否在青春期达到成人水平。使用适应的视觉变化检测任务,我们测量了VWM容量估计在13岁,16岁,和年轻的成年人。我们测试了在青春期早期或后期观察到的能力估计值是否与成年人的估计值相当。我们的研究结果表明,VWM的能力在整个青春期继续发展,甚至在16岁时也没有达到成人水平。这些研究结果表明,VWM能力显示了一个长期的发展,类似于在认知的各个其他方面观察到的长期轨迹。
The capacity of visual working memory (VWM) refers to the amount of visual information that can be maintained in mind at once, readily accessible for ongoing tasks. In healthy young adults, the capacity limit of VWM corresponds to about three simple objects. While some researchers argued that VWM capacity becomes adult-like in early years of life, others claimed that the capacity of VWM continues to develop beyond middle childhood. Here we assessed whether VWM capacity reaches adult levels in adolescence. Using an adaptation of the visual change detection task, we measured VWM capacity estimates in 13-year-olds, 16-year-olds, and young adults. We tested whether the capacity estimates observed in early or later years of adolescence were comparable to the estimates obtained from adults. Our results demonstrated that the capacity of VWM continues to develop throughout adolescence, not reaching adult levels even in 16-year-olds. These findings suggest that VWM capacity displays a prolonged development, similar to the protracted trajectories observed in various other aspects of cognition.
