Drew P. Cingel, a doctoral candidate in media, technology, and society at Northwestern University in Evanston, Ill., conducted the experiment when he was an undergraduate with the Media Effects Research Laboratory at Penn State University in University Park, Pa. under director S. Shyam Sundar. The researchers surveyed 228 6th, 7th, and 8th graders in central Pennsylvania on their daily habits, including the number of texts they sent and received, their attitudes about texting, and their other activities during the day, such as watching television or reading for pleasure. The researchers then assessed the students using 22 questions adapted from a 9th-grade grammar test to include only topics taught by 6th grade, including verb/noun agreement, use of correct tense, homophones, possessives, apostrophes, comma usage, punctuation, and capitalization.
Mr. Cingel, who published the study while at Wake Forest University in Winston-Salem, N.C., and Mr. Sundar found that the more often students sent text messages using text-speak (shortened words and homophones), the worse their grammar—a concern as 13- to 17-year-olds send more than twice the number of text messages each month than any other age group.
