Differential electrodermal and phasic heart rate responses to personally relevant information: Comparing sleep and wakefulness

2010

This study examined autonomic physiological responses to personally relevant information presented during sleep and wakefulness. Heart rate and electrodermal reactions to subjects’ own first name and other first names were measured during sleep stage 2, rapid eye movement (REM) sleep, and wakefulness. Across all conditions, larger skin conductance responses were elicited by subjects’ own first name. During REM sleep, personally relevant information led to larger heart rate acceleration, whereas an enhanced deceleration was examined during wakefulness. These findings suggest that auditory information is processed on a semantic level even during sleep. However, personally relevant information…
