Fourteen‐and six‐per‐second positive spikes in a nonclinical male population

Abstract

Fourteen-and 6/-sec. positive spikes occurred in 25.2% of a sample of a nonclinical population of 119 17- to 25-year-old men. The 2 groups could not be differentiated by menas of GCT [General Classification Test] scores, MMPI [Minnesota Multiphasic Personality Inventory] responses, CMI [Cornell Medical Index] scores, age, or responses to questions on a personal history questionnaire. Fourteen- and 6/-sec. positive spikes were not consistently found from one recording time to another in the same individual. Fourteen- and 6/-sec. positive spikes are seen in both stage 1 and stage 2 sleep. A higher prevalence rate would be found if the recording times were prolonged and if several records were obtained from each subject.
