Internal states can also have an impact on learning, shows study Apr 2 2021 We've all heard the adage, "If at first you don't succeed, try, try again," but new research from Carnegie Mellon University and the University of Pittsburgh finds that it isn't all about repetition. Rather, internal states like engagement can also have an impact on learning. The collaborative research, published in Nature Neuroscience, examined how changes in internal states, such as arousal, attention, motivation, and engagement can affect the learning process using brain-computer interface (BCI) technology. Findings suggest that changes in internal states can systematically influence how behavior improves with learning, thus paving the way for more effective methods to teach people skills quickly, and to a higher level of proficiency.
