Subjective sleep quality deteriorates with aging, but the extent to which this is a product of age itself, as opposed to the medical or psychiatric problems associated with aging, has not been carefully studied. To investigate this issue, we examined the subjective sleep quality of 44 healthy subjects over 80 years of age (20 men, 24 women), and 35 healthy(More)
OBJECTIVE AND METHOD Sleep disturbances are commonly reported by victims of extraordinary stress and can persist for decades. This study was designed to test the hypothesis that survivors of the Nazi Holocaust would have significantly more and different sleep problems than depressed and healthy comparison subjects and that the severity of the survivors'(More)
Non-response of the autonomic orienting response (OR), as indexed jointly by deficient skin conductance (SCR) and finger pulse amplitude responding (FPAR), has been shown to occur with excessive frequency in the schizophrenic population. The present study is an attempt to replicate earlier evidence that SCR-OR and FPAR-OR, when measured in concert, could(More)
Sixteen male outpatients with major depression and 20 age-equated healthy controls were awakened from rapid eye movement (REM) sleep between 1:30 and 3:30 AM, and the rapidity of return to REM sleep was determined. The time it took to return to REM sleep was reduced in depressives compared with controls: 61.6 (17.9 SD) min versus 80.6 (24.9 SD) min,(More)
Schizophrenic patients are frequently orienting nonresponders to innocuous stimuli, become responsive to significant target signals, and become hyporesponsive again on prolonged repetition. We wish to a) determine whether schizophrenic patients can display orienting response (OR) flexibility, responding to newly designated targets and ceasing to respond to(More)
