Our mission is to study children, teens, and emerging adults’ interaction with the newer forms of interactive digital media and to see how these interactions both affect and reflect their offline lives and long-term development. We endeavor to keep up with the latest technologies used by young people.

Welcome to the homepage of Children’s Digital Media Center, Los Angeles (CDMCLA), a collaboration between researchers at the University of California, Los Angeles (UCLA)  and California State University, Los Angeles (CSULA).  CDMCLA began in 2001 as part of a consortium funded for five years by the National Science Foundation. It is currently a collaborative effort between faculty, students, and visiting researchers in the Departments of Psychology at UCLA and CSULA.

We invite you to browse through these pages for more information about our projects and publications.

    Face Time Tops Screen Time

    By Daniel Akst

Most of us take for granted our ability to read emotions, such as anger or happiness, on the faces of others. But most adults came of age before computer screens became ubiquitous.

Researchers at the University of California, Los Angeles, wondered if all that screen time might be affecting children's ability to read emotions in others. To find out, they took advantage of a rustic science-education program, 70 miles east of L.A., which doesn't permit students to use electronic devices.

That let the scientists assess two groups of about 50 sixth-graders, each from the same public school. One group was at the program for five days, while the other hadn't yet attended. Both groups were tested on Monday and then again on Friday for their ability to detect emotions from people's faces. In two tests, each given twice, the pupils looked at 48 still photos and 10 videos scrubbed of verbal content.

After five days without electronics, the campers had pulled way ahead in reading faces. The camp group reduced its errors on the still-photo test by nearly twice as much as did the control group. (That the control group had any reduction at all was likely due to the practice offered by the first test, the scientists said.) On the video test, the campers improved by nearly 20% while the non-campers showed no change.

Overall, the children owned up to spending an average of 4.5 hours a day texting, watching TV and playing videogames. And the mix of screen time—TV versus phones, for instance—made no difference to the results. Nor did gender.

The findings suggest that children need more face time—and less screen time—to sharpen their social skills. But based on the results after just five screen-free days, improvement appears to be rapid.
