Recently, two research groups have reported that the depth and/or duration of Slow Wave Sleep (SWS) can be increased by playing short sounds with approximately 1 second intervals during or prior to SWS. These studies have used sounds with neutral or negative valence: sinusoidal I-kHz tones or short pink noise bursts. Since music therapy research shows(More)
In many data analysis tasks it is important to understand the relationships between different datasets. Several methods exist for this task but many of them are limited to two datasets and linear relationships. In this paper, we propose a new efficient algorithm, termed cocoreg, for the extraction of variation common to all datasets in a given collection of(More)
Individuals with job burnout symptoms often report having cognitive difficulties, but related electrophysiological studies are scarce. We assessed the impact of burnout on performing a visual task with varying memory loads, and on involuntary attention switch to distractor sounds using scalp recordings of event-related potentials (ERPs). Task performance(More)
Physiological changes, i.e., changes in the heart rate and its variability, respiratory patterns etc., are induced by listening to music. Both the low-level acoustic features of the sound and the perceived pleasantness of the music contribute to the type and strength of the physiological changes. Thus, for studying the effects of the pleasantness, it would(More)
