Even when turned off, a phone on the table can disrupt work

Smartphones can disrupt focus at work, even when they are turned off but in sight, according to scientists from the University of Paderborn. The researchers conducted a study involving 42 participants aged 20 to 34.

The volunteers were divided into two groups. One group performed tests with a turned-off smartphone nearby, while the other group left their phones in another room. Keeping the phones out of sight helped participants switch between different tasks more effectively and be more attentive.

This effect can be explained by the fact that people involuntarily glance at their phones even while working. As a result, the brain has to suppress the desire to use the device, such as reading messages. This process consumes cognitive resources, including working memory.
