The study investigates the effects of video game training on cognitive control in older adults. Using a custom-designed 3-D video game called NeuroRacer, researchers assessed multitasking performance across different age groups and found a linear decline in multitasking ability from ages 20 to 79. Older adults (60-85 years) who played NeuroRacer in multitasking training mode showed significant improvements in multitasking performance compared to both active control and no-control groups, with gains that persisted for six months. These improvements were accompanied by enhanced neural signatures of cognitive control, such as increased midline frontal theta power and frontal-posterior theta coherence. The training also led to enhanced sustained attention and working memory, with midline frontal theta power predicting these benefits. The findings highlight the plasticity of the prefrontal cognitive control system in older adults and demonstrate the potential of video games as a tool for cognitive enhancement.The study investigates the effects of video game training on cognitive control in older adults.
