SUMMARY The occurrence of lucid dreaming (dreaming while being conscious that one is dreaming) has been verified for 5 selected subjects who signaled that they knew they were dreaming while continuing to dream during unequivocal REM sleep. The signals consisted of particular dream actions having observable concomitants and were performed in accordance with pre-sleep agreement. The ability of pr...

In this paper we introduce the class of Wp scale mixture random vectors with a particular radial decomposition and a independent splitting property specified by some random variable Wp, p ∈ (0,∞). We derive several conditional limit results assuming that the distribution of the random radius is in the max-domain of attraction of a univariate extreme value distribution andWp has a certain tail a...

College women who are prehypertensive and matched controls were exposed to emotion-provoking situations, psychologic tests, and psychiatric interviews. Patterns of response differentiating the groups were observed. The prehypertensives were less well controlled, more impulsive, more egocentric, and generally less adaptable in the stressful situations. In the psychiatric interviews, behavior sim...

All 12 cases who received a diagnosis of depersonalisation neurosis over a 6½ year period were studied. The illness was found to occur in young males. It usually took a deteroriating course after starting insidiously. Anxiety, depression and derealisation were common concomitants. Other associated symptoms included deaffectualisation, disturbed sleep and appetite, obsessive ruminations and hypo...

ume to or from the lung affect the pulmonary capillary blood volume (Vc) as measured with carbon monoxide diffusing techniques.'-5 However, the available information suggests that this mechanism is inadequate to explain the larger increases in diffusing capacity (DL,.O ) observed during exercise.1-6 Other concomitants of exercise which have been examined do not affect DL00.7' 8 The purpose of t...

We review neural correlates of perceptual and motor decisions, examining whether the time they occupy explains the duration and variability of behavioral reaction times. The location of a salient target is identified through a spatiotemporal evolution of visually evoked activation throughout the visual system. Selection of the target leads to stochastic growth of movement-related activity towar...

Although little is known empirically of the physiology of human hunting, arguments for innate biological bases of gender-dimorphic behaviors such as aggression frequently point to the role of hunting in human evolution. Study of !Kung San hunter-gatherer men demonstrated that the diurnal pattern in serum testosterone was altered during a six-day hunt, compared to pre- and post-hunt levels, due ...

Historically, industrialization has been associated with falling relative returns to skills. This fact is at odds with most unified theories of industrialization, which tend to imply rising skill premia as natural concomitants to economic growth. This paper develops a very simple model of historical growth to help solve this puzzle. Assuming that human capital is both a consumption good and an ...
