Figure 2

Selective sleep suppression and general affect. (a) REM sleep was significantly more reduced in the REMS group than in the other two groups, whereas SWS suppression was significantly stronger in the SWSS group than in the other two groups. Suppression scores for REM (SWS) sleep are the difference of percentage REM (SWS) of TST between the habituation night minus the experimental night. (b) Ratings of general positive and negative affect, measured with the Positive And Negative Affect Scale (PANAS)59 on the mornings after the habituation night and after the experimental night, separately for the three groups. (c) Changes in negative (right) but not positive affect (left) from the habituation night to the experimental night correlate significantly with REM sleep suppression scores across all groups. Shaded areas represent 95% confidence intervals for simple bivariate regression. Error bars represent standard error of the mean. n.s. not significant.
