Keeping the lights on in the cave shouldn't make any difference since it is the individual who is deciding, not an external 24-hour driven event. My recollection is that the rhythm is not specifically 25 hours but is nevertheless longer than 24 hours and varies in individuals as to how much longer.
Nevertheless, we are probably older due to all the stress of keeping up with the alarm clocks! --Mike --- On Thu, 7/31/08, John Kulig <[EMAIL PROTECTED]> wrote: From: John Kulig <[EMAIL PROTECTED]> Subject: RE: [tips] info: brain birthday calendar To: "Teaching in the Psychological Sciences (TIPS)" <[email protected]> Date: Thursday, July 31, 2008, 11:09 AM It is my understanding, based on hallway conversations form someone who DOES know this area, that it is a 24 hour clock with a margin of error, and the margin of error allows the clock to drift, which permits adjustments and resettings. As to why, in a cave, it drifts to 25 and not 23, I may ask him. Most of us have a tendency to stay up later when stimuli are present ..... and isn;t it true that in the "cave" research participamts are free to keep lights on as long as they wish? ----------------------------- John W.
