Attending Lectures Stimulates the Brain as much as Watching TV

Source: MIT news office, Mar 2013

During the first panel, “Blended Models of Learning: Bringing Online to On-Campus,” Eric Mazur, a professor of physics at Harvard, cited a study (see PDF) by MIT professor of media arts and sciences Rosalind Picard and her students in which subjects were fitted with wristbands that measured skin conductance as an index of the “arousal associated with emotion, cognition and attention.”

Mazur presented a figure from the Picard group’s paper showing wrist-sensor readings for a single MIT student over the course of week. The sensor recorded regular, strong spikes during periods of study, lab work and homework, but the readout flatlined during two activities: attending class and watching TV.
