title: Daytime state and night-time sleep; a sleep study after a marathon group experience.
abstract: The nocturnal sleep of 9 subjects was recorded under two conditions following a "normal" weekend and following a weekend in which the subjects participated in a psychodynamic marathon group activity. Differences between the two experimental conditions were found for sleep latency and on one measurement of D-latency. Both latencies were reduced after the marathon group. No differences were found on the remaining 12 measurements. These findings tend to reaffirm the stability of sleep patterns under various pre-sleep conditions.
