Torkel Klingberg was the first to investigate whether intensive training of working memory has beneficial effects on other cognitive functions. His pioneering study suggested that working memory can be improved by training in ADHD patients through computerized programs. This study has found that a period of working memory training increases a range of cognitive abilities and increases IQ test scores. Another study of the same group has shown that, after training, measured brain activity related to working memory increased in the prefrontal cortex, an area that many researchers have associated with working memory functions. It has been shown in one study that working memory training increases the density of prefrontal and parietal dopamine receptors (specifically, DRD1) in test persons. However, subsequent work with the same training program has failed to replicate the beneficial effects of training on cognitive performance. A meta-analytic summary of research with Klingberg's training program up to 2011 shows that this training has at best a negligible effect on tests of intelligence and of attention

托克尔 · 克林伯格是第一个研究工作记忆强化训练是否对其他认知功能有益的人。他的开创性研究表明，通过电脑程序训练 ADHD 患者的工作记忆能够得到改善。这项研究发现，一段时间的工作记忆训练可以提高一系列的认知能力，并提高 IQ 测试成绩。另一项针对同一群体的研究表明，经过训练后，测量的与工作记忆有关的大脑活动在脑前额叶外皮中增加了，这个区域被许多研究人员与工作记忆功能联系在一起。一项研究表明，工作记忆训练增加了受试者的前额叶和顶叶多巴胺受体(特别是 DRD1)的密度。然而，后续的工作与同样的训练计划已经无法复制训练对认知表现的有益影响。克林伯格2011年之前的训练计划的研究的元分析总结表明，这种训练在智力和注意力测试中充其量只有微不足道的效果

在另一项有影响力的研究中，工作记忆任务(双 n-back 任务)训练提高了健康年轻人在流体智力测试中的表现。2010年重复了通过 n-back 任务训练提高流体智力的实验，但2012年发表的两项研究未能重现这一效果。大约30个关于工作记忆训练有效性的实验研究的综合证据已经被一些元分析评估。关于工作记忆训练是否能提高智力，这些元分析的作者不同意他们的结论。然而，这些元分析对工作记忆训练效果的估计是一致的: 如果有这样的效果，那么它可能是很小的。
