In an often replicated experiment, college age subjects were asked to complete two tests. One required them to solve math problems while simultaneously remembering a random series of numbers. The other required them to solve problems using pattern recognition or inference skills. They were sorted into three groups based on their phone location:
- Group 1: phones on desk
- Group 2: phones in pocket or bag
- Group 3: phone in another room
The results indicated that all three groups self-reported not thinking about their phone at all during the time they were completing the tests. However, the results of their tests indicated differently. Predictably:
- Group 1 had the lowest working memory capacity and fluid intelligence
- Group 3 had the highest
- Group 2 fell in the middle
The researchers’ interpretation of their results said, “the mere presence of one’s smartphone may impair cognitive functioning even when it does not occupy the contents of consciousness.”
As our students are in the final stretch of the school year we can share the results of this study with them. They can do their best work and achieve their best results when their phone is located in another room while they are focusing and concentrating.
