| Inciting instead of coercing, 'nudges' prove their effectiveness Posted: 17 Jan 2022 06:30 AM PST To get through challenges such as the pandemic or the climate change, citizens must change their habits and behaviors. But how can this be achieved without resorting to coercive measures? The answer to this question may be the 'nudges' that have been gaining popularity over the last decade. By making small changes in our environment, these interventions aim to encourage changes in our behavior, while preserving our freedom of choice. From adding informative labels to reorganizing the food offer in a cafeteria, the overall effectiveness of these interventions has now been demonstrated. |

| The free-energy principle explains the brain Posted: 14 Jan 2022 04:45 AM PST The free-energy principle can explain how neural networks are optimized for efficiency, according to new research. This finding will be useful for analyzing impaired brain function in thought disorders as well as for generating optimized neural networks for artificial intelligences. |
| Like our social media feeds, our brains take a little while to update Posted: 13 Jan 2022 04:41 PM PST Our brains are constantly uploading rich visual stimuli. But instead of seeing the latest image in real time, we actually see earlier versions because our brain's refresh time is about 15 seconds. The findings add to a growing body of research about the mechanism behind the 'continuity field,' a function of perception in which our brain merges what we see to give us a sense of visual stability. |
