Cellphones and laptops can be distracting for students in classrooms, and new research also shows that using electronic devices can even lower students’ grades.

Scientists who studied the effects of divided attention in people know that when attention is divided between two tasks, fewer items regarding those tasks may be recalled later — a concept called “retention” in psychology.

Additional research on electronic devices shows that smart phones can reduce the ability to think to a person’s full potential, and additional research from Stanford University reveals that intense multitasking decreases the efficiency of completing a given task.
