It is clear that multitasking behavior has become ubiquitous in today’s technologically-dense world 3, and substantial evidence has accrued regarding multitasking difficulties and cognitive control deficits in our aging population 4. Humans regularly challenge these control processes when attempting to simultaneously accomplish multiple goals (i.e., multitasking), generating interference as the result of fundamental information processing limitations 2. Pre- and Post-training evaluations involving cognitive testing and NeuroRacer EEG took place across 3 different days (appointment and individual test order were counterbalanced), with all sessions completed approximately within the span of a week (total number of days to complete all Pre-training testing: 6.5 days ± 2.2 Post-training testing: 6.1 days ± 1.5).Cognitive control is defined by a set of neural processes that allow us to interact with our complex environment in a goal-directed manner 1.Critically, this training resulted in performance benefits that extended to untrained cognitive control abilities (i.e., enhanced sustained attention and working memory), with an increase in midline frontal theta power predicting the training-induced boost in sustained attention and preservation of multitasking improvement six months later. Furthermore, age-related deficits in neural signatures of cognitive control, as measured with electroencephalography, were remediated by multitasking training (i.e., enhanced midline frontal theta power and frontal-posterior theta coherence). By playing an adaptive version of NeuroRacer in multitasking training mode, older adults (60–85 y.o.) reduced multitasking costs compared to both an active control group and a no-contact control group, attaining levels beyond that of untrained 20 year olds, with gains persisting for six months.
Neuroracer Free All VersionPerformance was evaluated using two distinct game conditions: 1) ‘Sign Only’- respond as rapidly as possible to the appearance of a sign only when a green circle was present, and 2) ‘Sign & Drive’- simultaneously perform the sign task while maintaining a car in the center of a winding road using a joystick (i.e., ‘drive’ see Figure 1a). 174 participants spanning six decades of life (ages 20–79 ~30 individuals per decade) played a diagnostic version of NeuroRacer to measure their perceptual discrimination ability (’sign task’) with and without a concurrent visuomotor tracking task (‘driving task’ see Supplementary Materials for details of NeuroRacer). Think fast & Run fast Become a neuro champion, speed up your brain by solving math facts in this amazing endless runner game.In a first experiment, we evaluated multitasking performance across the adult lifespan. •Cited by 1421 By playing an adaptive version of NeuroRacer inDownload Neuro Runners and enjoy it on your iPhone, iPad, and iPod touch. Scientists find that a multitasking driving game called NeuroRacer makes the brains of octogenarians behave decades younger.

A, Screen shot captured during each experimental condition. A ‘cost’ index was used to assess multitasking performance by calculating the percentage change in d’ from ‘Sign Only’ to ‘Sign & Drive’, such that greater cost (i.e., a more negative % cost) indicates increased interference when simultaneously engaging in the two tasks (see Methods Summary).NeuroRacer experimental conditions and training design.Thus, using NeuroRacer as a performance assessment tool we replicated previously evidenced age-related multitasking deficits 7, 8, and revealed that multitasking performance declines linearly as we advance in age beyond our twenties.NeuroRacer multitasking costs. This deterioration in multitasking performance is consistent with the pattern of performance decline across the lifespan observed for fluid cognitive abilities, such as reasoning 5 and working memory 6. This assured that comparisons would inform differences in the ability to multitask, and not merely reflect disparities in component skills (see Methods, Supplementary Figures 1 & 2, and Supplementary Materials for more details).Multitasking performance diminished significantly across the adult lifespan in a linear fashion (i.e., increasing cost, see Figure 2a and Supplementary Table 1), with the only significant difference in cost between adjacent decades being the increase from the 20s (−26.7% cost) to the 30s (−38.6% cost). ![]() ![]() 001).Next, we assessed if training with NeuroRacer led to generalized enhancements of cognitive control abilities that are known to be impaired in aging (e.g., sustained attention, divided attention, working memory see Supplementary Table 2) 12. Interestingly, the MTT group’s Post-training cost improved significantly beyond the cost level attained by a group of 20-year-olds who played a single session of NeuroRacer (−36.7% cost Experiment 3 p<. Notably in the MTT group, the multitasking performance gains remained stable 6 months after training without booster sessions (at 6 months: −21.9% cost). Dolphin emulator issues on macVigilance Test of Variables of Attention (TOVA) 13) only for the MTT group ( Figure 3c see Supplementary Table 2). Consistent with our hypothesis, significant group X session interactions and subsequent follow-up analyses evidenced Pre- to Post-training improvements in both working memory (delayed-recognition task with and without distraction 7 Figure 3a,b) and sustained attention (i.e.
