A recent study in Research in Higher Education Journal demonstrates that texting has a negative impact on grade performance.  Researchers randomly split an introductory accounting class of sixty-two students in half. One half was requested to text the professor three times during a lecture, the other half was requested to refrain from texting during the lecture. Unknown to the students was that they would be taking a test after the lecture.
Texting students achieved a 42.81 mean, non-texting students received a 58.67 mean, a statistically significant difference. Controlling for gender, the study found no differences, that is, females who texted did worse than females who did not text. They also controlled for GPA (grade point average). Students with higher GPAs who text did not perform as well on the test as high GPA students who did not text.
Neuroscience suggests that for memory tasks that require understanding and recalling unfamiliar material, multitasking reduces performance. It would appear that texting is a distraction that negatively impacts performance when engaging with unfamiliar material.
What is the bottom line for the average working stiff? Although multitasking might seem like a productivity boon, it isn’t. In fact, it could decrease your performance.
I’m going to leave you with a quote from John DallaCosta, Centre for Ethical Orientation about Broken Busy-ness:
“We adhere to busy-ness to get done the most possible within our talents. But it is a trap locking us into the churn of never doing enough, never catching up, never attaining what truly satisfies.”
