Depriving rats of REM sleep: the identification of a methodological problem.

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 it is shown that the discrepant outcomes in the literature could be the result of inattention to that ratio.

Cultural deprivation and the relative preferences of preschool children for complex and novel stimuli.

To determine their relative effects, the preferences of 19 deprived and 21 non-deprived preschoolers for both complex stimuli and novel stimuli was measured. The deprived children showed a lack of preference for the novel stimuli but did not differ from the non-deprived group in their preference for complexity. These data clarified a confounding of these stimulus dimensions which had occurred in previous studies.

Perception of less irregular and more irregular stimuli.

Berlyne's stimuli were presented in a stereoscope to test his hypothesis that Ss prefer the more irregular member of a pair of stimuli. 32 Ss, screened for normal acuity and phorias, were tested. Contrary to Berlyne's hypothesis and consistent with earlier stereoscopic studies, Ss tend to report more frequently the less irregular member of a pair of stimuli. These data can be explained by an information-conflict model; however, the clearest implication of this study was that experiments concerned with familiarity of stimuli should be qualified by the method.

Attitudes of major employers toward the employment of people with epilepsy: a 30-year study.

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.
