Are Errors Indicative of Learning Strategies: Use It or Minimize It?

Noise is Better for Human Brain Than Ordered Signal: The fascinating connection between human consciousness and noise highlights the essential role of noise in shaping our thoughts, perceptions, and emotions. Here, we explore the downside of not finding a predetermined pattern of signal transmission in the brain, while also highlighting the positive aspects of noise as the brain’s true signal of conscious processes. We picked tasks that engage either the left or right side of the brain. For example, we looked at mathematical operations that typically involve the left hemisphere. While someone solved math problems, we used EEG to track how the results moved from the left to the right hemisphere when they communicated those results using sign language with their left hand, which requires the right hemisphere. Next, we reversed things. We focused on tasks related to recognizing art, something usually processed by the right hemisphere. Participants looked at a picture for about 12–15 s, and we could see their brain’s image processing region activate in the EEG. Then, we removed the picture and showed them a mix of jumbled-up picture details, including the one they'd seen. To answer, they had to access the image data stored in the right hemisphere, then use language processing in the left hemisphere to describe it and communicate the answer using sign language with their right hand. Through EEG, we observed clear transfers of information between the left and right hemispheres of the brain. Our study revealed that each person’s brain follows a unique information processing and transfer protocol between these hemispheres. We also found that ASMR can enhance this interhemispheric transfer, while periodic buzzer sounds can inhibit it. Brain plasticity, or its ability to adapt, appears to be linked to an individual’s typical cognitive processes.
