You would think people might have learned from BF Skinner not to experiment on their own children, but a Dad at UCLA is busily hooking up sensors to everything and everybody in a first grade classroom–a project that was inspired by his daughter. The sensors will track where the students go, what they look at, and will record everything they say.
You might wonder about the ethical considerations of such a project. Maybe only I do. In any event, I have started looking at the intersection of privacy preferences and content rights at the intersection of real physical and media spaces. Leaving aside questions of whether the seven-year-olds or their parents are aware of the potential hazards of such research, there are serious questions of incidental collection (are the people who the students talk to recorded) and combinatorial privacy (will data mining reveal connections that invade private realms that surface recording of events may not), among others.
All of this gives me yet another reason to have some kids: research subjects!
