Using 30 Sprague-Dawley female rats, threshold to pain was measured over the course of recovery from REM sleep deprivation. Relative to the untreated controls and to their own pretreatment thresholds, the REM-deprived animals showed significantly reduced pain thresholds which were still evident 96 hours after the termination of the REM deprivation.

The handedness distribution of a group of 578 gifted elementary school children (I.Q. = 132) was compared to handedness distribution of 391 non-gifted children (I.Q. less than 132), with the result that the gifted group was significantly less right-handed than their non-gifted peers. These data were discussed relative to Bakan's hypothesis that(More)
Several studies that used Jouvet's platform-in-the-water technique to deprive rats of REM sleep are reviewed. It is observed that a consistent feature of the design of these studies was to ignore the ratio between the size of the animal and the diameter of the platform when the REM deprivation was manipulated. Some contradictory studies are considered, and(More)
As evidence for an hypothesis that pupil size plays an important role in nonverbal communication, Hess (1975) has reported that adults draw in appropriately sized pupils on his happy and angry faces task. However, he did not report a statistical test of his data. In this study, we replicated Hess' research and found congruent with his hypothesis that(More)
Beginning in 1956, major San Francisco Bay area employers were sampled at 10-year intervals for a 30-year period to assess attitudes toward the employment of epileptic workers. In this time, we documented a trend of sustained positive change that appears to validate the efforts of organizations that have focused on raising public awareness of this disorder.
