In study, real-time feedback on metrics of collaborative processes failed to boost performance, collective intelligence

A new study by Carnegie Mellon University researchers found that real-time feedback on collaboration metrics does not improve team performance and can even make it worse. By narrowing the feedback to a single metric, teams focused too much on that signal and neglected coordination strategy, leading to decreased overall performance.

ECNU Review of Education study explores how large language models can revolutionize teaching as personalized assistants

A study explores how large language models (LLMs) can transform teaching by generating customized educational materials, assessing student progress, and providing targeted feedback. LLMs excel at automating routine tasks, reducing teachers' workload and enabling them to focus on mentoring students.

What social rejection teaches your brain

A USC study reveals that forming social ties relies on learning from positive outcomes, such as rewards, and tracking relational value. The findings help explain why we are drawn to certain people and how we navigate relationships, with implications for mental health and social behavior.

Study indicates delayed feedback enhances learning performance in individuals with traumatic brain injury

A novel study found that delayed feedback improves learning outcomes for individuals with moderate-to-severe traumatic brain injury. Delayed feedback may engage brain regions associated with memory retrieval and confidence, bypassing impaired pathways. The study suggests a valuable tool for improving learning in TBI individuals.

Pink elephants in the brain?

A study published in Neuron reveals that neurons are wired to connect seemingly unrelated concepts, enhancing the brain's ability to predict what we see based on past experiences. Visual experience influences the organisation of feedback projections, which store information about the world.

Subtropical clouds key to southern ocean teleconnections to the tropical pacific

A research team at UNIST has identified subtropical low cloud feedback as a key mechanism driving teleconnections between the Southern Ocean and tropical precipitation. Their findings suggest that this impact is stronger than previously thought, with implications for mid-latitude climate predictions.

Changes in oxygen concentrations in our ocean can disrupt fundamental biological cycles

Researchers found that a decline in ocean oxygen can break down feedback mechanisms controlling the marine nitrogen cycle, which is essential for all forms of life. The team used a data-constrained earth system model to show that extreme deoxygenation can lead to a collapse of the ocean's bioavailable nitrogen inventory.

Helping the nose know

Researchers describe how feedback mechanism works by identifying where signals go and which neurons receive them. The study reveals that higher brain regions communicate with lower parts of the brain on a near-constant basis, helping to interpret olfactory information.

Shrinking snow and ice cover intensify global warming

New research from the University of Michigan reveals that decreasing snow and ice cover in the Northern Hemisphere has exacerbated global warming, with a stronger positive feedback mechanism than initially predicted. The study shows that the cryospheric albedo feedback is almost twice as strong as models have simulated, contributing to...

Sahara's abrupt desertification started by changes in Earth's orbit, accelerated by atmospheric and vegetation feedbacks

German scientists used a climate model to conclude that the Sahara's desertification began abruptly 5,440 years ago due to subtle changes in Earth's orbit. The resulting desertification had significant impacts on ancient civilizations, with some of the most severe changes occurring between 4,000 and 3,600 years ago.
