title = "Effects of a cognitive intrusion manipulation on the sleep-onset latency of good sleepers",
abstract = "Thirty-eight female good sleepers were instructed to go to sleep as quickly as possible in a daytime nap session under one of three instructional sets designed to manipulate the likelihood of cognitive intrusions. Subjects informed that they would be required to present a speech after their sleep period and told the topic of the speech required significantly longer to fall asleep and obtained less sleep than subjects in two control conditions. Analysis of heart rate and skin conductance measures failed to support the mediational role of autonomic activity in retarding sleep-onset.",

note = "Funding Information: While physiological hyperactivity has been advanced as a hypothesized mediator for insomnia (e.g., Monroe, 1967), subsequent comparisons of insomniacs and good sleepers have not corroborated this view (VanOot, Lane, & Borkovec, in press). A competing theory suggests cognitive hyperactivity as the underlying mechanism. This notion derives support from the frequently replicated finding of elevated MMPI profiles, characterized by the neurotic triad among insomniacs (e.g., Carskadon, Dement, Mitler, Guilleminault, Zarcone, & Spiegel, 1976; Coursey, Buchs-baum, & Frankel, 1975), the finding of dysphoric daydreaming styles among poor sleepers (Starker & Hasenfeld, 1976), clinical observations of obsessive worry over sleep reported by insomniacs (Hauri, Note 1; Roth, Kramer, & Lutz, 1976), and the reduction of cognitive intrusion This study was based on the honors thesis of the first author at the University of Iowa.
