NO RESPITE DURING SLEEP - HEART-RATE HYPERREACTIVITY TO RAPID EYE-MOVEMENT SLEEP IN ANGRY MEN CLASSIFIED AS TYPE-A

9 men scoring as Type A and Angry and 9 men scoring as Type B and Nona ngry on the Jenkins Activity Survey and Spielberger's Trait Anger Expr ession completed a 1-min. mental arithmetic task and slept through 1 p eriod of rapid eye movement. The Angry Type A scorers showed greater h eart-rare increases from baseline to that during mental arithmetic and from nonrapid eye movements ro periods of REM than the Nonangry Type B scorers. While the former showed equivalent reactivity to stressors while awake and asleep, the latter group showed less heart-rare reacti vity during the period of REM than during mental arithmetic. Neither g roup yielded clear descriptions of their dreams, and no differences be tween groups were noted for ratings on aggressivity in dreams. It appe ars that Angry Type A scorers show cardiovascular hyperreactivity even when asleep in the lab.
