Q & A with Dr. Bruce/reem


By Kimberly Moore Kneas, Ph.D. and Bruce D. Perry, M.D., Ph.D.
Early Childhood Today: Are young children's brains (ages three through six) well suited to the use of technology? (We define technology as children using cameras, computers, tape recorders and video cameras in classroom projects.) If so, how? Are some forms of technology better than others for these specific age levels?
Dr. Perry: In order to answer that question we must consider some of the genetic biases of the human brain. For 99 percent of the time we have been on the planet, we lived in small hunter-gatherer groups of about 40 to 50 people. Our brains developed specialized capabilities for social affiliation, communication and various kinds of symbolic representation. Our cultures evolved through social interactions, initially without written language. The development of written language changed the way human beings developed, in large part by influencing brain development and expressed new brain-mediated capabilities that had previously been un-expressed.
I see technology doing the same things today. The brain clearly could not have a "genetics" specific for the use of a joystick. Nor could the brain have a genetics specific for continuous attention to a two-dimensional moving image such as those in the television. Yet external symbolic representation such as the written word, visual images on television, and complex three-dimensional videography are all sensed, processed, stored, and acted on by the human brain. Because the brain literally changes in response to experiences, these "new" (from a historical perspective) experiences (the written word or television) cause changes in brain development, brain organization, and brain function that were never expressed hundreds of generations ago.
Modern technologies are very powerful because they rely on one of the most powerful genetic biases we do have — the preference for visually presented information. The human brain has a tremendous bias for visually presented information. Television, movies, videos, and most computer programs are very visually oriented and therefore attract and maintain the attention of young children.
The problem with this is that many of the modern technologies are very passive. Because of this they do not provide children with the quality and quantity of crucial emotional, social, cognitive, or physical experiences they require when they are young. The developing child requires the right combination of these experiences at the right times during development in order to develop optimally. This cannot happen if the child is sitting for hours passively watching television.
Sitting young children in front of a television for hours also prevents that child from having hours of other developmental experiences. Children need real-time social interactions; technology such as television can prevent that from happening.
On the other hand there are many positive qualities to modern technologies. The technologies that benefit young children the greatest are those that are interactive and allow the child to develop their curiosity, problem solving and independent thinking skills.
ECT: Do you see the use of specific things like computers as part of an early childhood curriculum as being powerful enough to change brain development the same way you've just described television?
Dr. Perry: Absolutely. I think the difference between computers and television is that television tends to be quite passive. You sit and you are watching and things are happening in front of you but you don't do anything. Children are natural "manipulators" of the world — they learn through controlling the movement and interactions between objects in their world — dolls, blocks, toy cars, their own bodies. With television, they watch and do not control anything. Computers allow interaction. Children can control the pace and activity and make things happen on computers. They can also repeat an activity again and again if they choose.
