Hypnotizability, Sleepiness, and Subjective Experience

Absorption, openness to experience, and hypnotizability.

Absorption, a correlate of hypnotizability, is conceptually related to openness to experience. Study 1 found no evidence that gender moderated the correlation between absorption and hypnotizability, or of nonlinear trends. Study 2 showed that openness was factorially complex, and that absorption was related to imaginative involvement, but not to social-political liberalism. Study 3 found small ...

Yawning and subjective sleepiness in the elderly.

Yawning is related to sleep/wake transitions and time of day, probably reflecting the time course of sleepiness. As aging modifies sleep-wake and sleepiness rhythms, we suppose that yawning frequency and its time course vary as a function of age. Thirteen aged healthy subjects (77.15 +/- 4.09 years) and 12 young adults (24.41 +/- 3.31 years) were instructed to keep their habitual sleep schedule...

Subjective sleepiness and accident risk avoiding the ecological fallacy.

The present study of sleepiness and accident risk in a HI-FI car simulator aimed to provide subject-level relative risks (RR) with 95% confidence intervals (CI) for different levels of subjective sleepiness measured with the Karolinska Sleepiness Scale (KSS), 1 = very alert, 9 = very sleepy, fighting sleep, an effort to staying awake. Five male and five female shift workers, mean age 37 years, ...

Subjective Daytime Sleepiness and Related Predictors in Finnish Schoolchildren

Daytime sleepiness in children and adolescents has negative consequences on schoolchildren's daily life and functioning (1-3). Thus it is important to evaluate the prevalence of daytime sleepiness and to find out its predictors. The prevalence of excessive daytime sleepiness in children and adolescents has varied between 0 and 35% in epidemiological studies (4-10). An increase of daytime sleepi...
