Locus of control in short and long sleepers.
As a test of the hypothesis that consistent short sleepers tend to be less reflective and more conformist in their thinking than long sleepers, the I-E scale scores of 15 short and 15 long sleepers were compared. Consistent with this hypothesis, we found that to a significant degree, short sleepers view themselves as more externally regulated than long sleepers.
