Two Massachusetts Institute of Technology students have developed a device called the Pavlov Poke that's intended to help them break their Facebook addictions. The gadget that resides inside a keyboard rest detects when a user has accessed Facebook and doles out painful electric shocks. "To be truly effective, many shock exposures are probably needed. ... Sadly, we found the shocks so aversive, we removed the device pretty quickly after installing it," said Robert Morris, one of the students.
