The extent to which sentence imagery elicits effects comparable to those produced by long narratives was investigated. Smokers imagined sentences with varying affective content and that either contained or were devoid of smoking cues. Physiological responses were monitored, and smokers rated their urges and affect. Startle responses were also collected as an index of negative affect processing. Smoking-cue sentences produced augmented urges and startle responding. Smoking material also elevated negative affect during imagery of positive affect sentences. The affect manipulation produced changes in self-reported affect and facial electromyography consistent with the affective valence of the sentences. This procedure is similar to narrative imagery in the manipulation of smoking urges and affect under laboratory conditions. Results support the hypothesis that smoking urges enhance negative affect processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

From previous studies, chippers (very light, long-time cigarette smokers) seem not to be nicotine dependent, despite decades of smoking. The effect of tobacco deprivation on chippers' withdrawal reactions was examined. Matched groups of 26 chippers and 25 regular smokers were studied while abstaining or smoking for 2-day blocks, with assessments administered 5 times daily by palm-top computers. As hypothesized, chippers showed no changes as a result of nicotine deprivation. In contrast, regular smokers demonstrated distinct changes in craving, mood, arousal, and sleep disturbance. The computers also tested participants' cognitive performance. Unlike chippers, regular smokers' performance on complex tasks was slower under deprivation; the effect could not be explained by changes in motor performance or simple reaction time. Results suggest performance may have been improved by nicotine rather than worsened by withdrawal. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

One of Canada's newest hospices, located in Oakville, Ont., was designed to help dying patients live and die peacefully. Another of its important roles is to help family members cope with the uncertainty and loneliness that surrounds a death in the family. "There are so many people out there without support," says its founder, Margaret Anderson. 相似文献

The impact of a transdermal nicotine patch on smokers' craving for cigarettes and reactivity to smoking cues was investigated. Sixty-one smokers were assessed during 2 sessions separated by 6 hr. Cue reactivity to imaginal and in vivo smoking and nonsmoking stimuli was evaluated during both sessions. During the interval between sessions, participants were abstinent from cigarettes and wore either a nicotine transdermal (21 mg) or placebo patch. In both sessions, exposure to in vivo and imaginal smoking stimuli elicited cue-specific increases in craving, negative affect, vividness, heart rate, and skin conductance. The nicotine patch attenuated craving and other effects induced by abstinence from cigarettes but had no selective impact on craving or any other reaction elicited by smoking cues. These results are discussed in terms of models of craving and clinical implications of transdermal nicotine for craving reduction. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
