Rhythm is perceptually salient to the listener. This claim is central to the research project briefly described below: a large-scale investigation of listening, in which the principal issue was how listeners segment continuous speech into words. Listeners must recognize spoken utterances as a sequence of individual words, because the utterances may never previously have been heard. Indeed, list...

The chronological distributions of enamel hypoplasias (indicators of nonspecific stress) are assessed for 111 individuals from two prehistoric populations from Dickson Mounds, Lewiston, Illinois. The earlier population (circa A.D. 950-1150) involves a transition from an indigenous gathering-hunting tradition to increasing adoption of Mississippian lifeways. The later population (circa A.D. 1150...

Sustained weightlessness affects all body functions, among these also cardiac autonomic control mechanisms. How this may influence neural response to central stimulation by a mental arithmetic task remains an open question. The hypothesis was tested that microgravity alters cardiovascular neural response to standardized cognitive load stimuli. Beat-to-beat heart rate, brachial blood pressure, a...

In 1988, Andersen and Williams proposed a model to explain the stressinjury relationship. The present study tested portions of this framework by investigating frequency and severity of injury occurrence in track and field athletes from four NCAA Division I and I1 universities. Personality characteristics (locus of control and sport competition trait anxiety), history of stressors (life stress, ...

OBJECTIVE Although an association between energy drinks and suicide has been suggested, few prior studies have considered the role of emotional factors including stress, sleep, and school performance in adolescents. This study aimed to evaluate the association of energy drinks with suicide, independent of possible confounders including stress, sleep, and school performance. METHODS In total, ...
