A new study has found that intelligence, in the form of general cognitive abilities such as perception, thinking and remembering, is more important than hitherto thought at predicting a person’s ability to complete common tasks with a PC. The study was published in the International Journal of Human-Computer Studies in August 2024.

“Our research findings are the first clear proof that cognitive abilities have a significant, independent and wide-ranging effect on people’s ability to use a computer. Contrary to what was previously thought, cognitive abilities are as important as previous experience of computer use,” says Aalto University’s Professor Antti Oulasvirta, who studied human-computer interaction extensively with his team.

The findings ha...

Electrodes for brain research
Virginia Tech researchers with the Fralin Biomedical Research Institute at VTC Center for Human Neuroscience Research construct carbon fiber microelectrodes for real-time detection of dopamine and serotonin activity in human patients. The in-house, custom-made electrodes are narrow and used during deep brain stimulation electrode implantation surgeries to measure activity of both dopamine and serotonin in patients.
