Iniulat ng AI Larawang ginawa ng AI Fact checked
University of Notre Dame researchers report evidence that general intelligence is associated with how efficiently and flexibly brain networks coordinate across the whole connectome, rather than being localized to a single “smart” region. The findings, published in Nature Communications, are based on neuroimaging and cognitive data from 831 Human Connectome Project participants and an additional 145 adults from the INSIGHT Study.

Researchers have conducted the first quantitative study on post-game depression, concluding that role-playing games trigger the strongest feelings compared to other genres. The study, involving 373 participants, was published in the Current Psychology journal. RPG completers showed stronger depressive symptoms and emotional processing disturbances.
Neuroscientists at Northwestern University have demonstrated that subtle sound cues during REM sleep can influence dream content, leading to improved creativity in solving brain teasers. In a study with 20 participants, 75% reported dreams related to cued puzzles, which they solved at higher rates the next day. The findings suggest sleep may play a key role in creative problem-solving.

A University of Illinois Urbana-Champaign study of 589 U.S. adults found that people who more often “savor” positive experiences with their partner—by revisiting good memories, enjoying the moment, or anticipating future events—reported higher relationship satisfaction, less communication conflict and greater confidence their relationship will last. The analysis also suggests joint savoring may help buffer the negative link between stress and both relationship confidence and psychological distress.
A new brain imaging study has found that recalling facts and personal experiences activates nearly identical neural networks, challenging long-held views on memory systems. Researchers from the University of Nottingham and University of Cambridge used fMRI scans on 40 participants to compare these memory types. The results, published in Nature Human Behaviour, suggest a rethink in how memory is studied and could inform treatments for Alzheimer's and dementia.

New research suggests that having a positive impact on other people is a crucial element in feeling that life has meaning. Psychologists Joffrey Fuhrer and Florian Cova analyzed surveys to identify four dimensions of meaning, including this new factor beyond traditional ones like coherence and purpose. Their findings highlight how helping others, even in small ways, can enhance personal fulfillment.
