糖尿病与睡眠的相互关系 总被引:2,自引:0,他引:2
人一生中有1/3的时间在睡眠中度过,睡眠质量直接关系到一个人的身体健康。睡眠时间过少或过多的人糖尿病患病率大大增加。糖尿病本身的病理、生理特点,严重影响患者的睡眠质量,睡眠质量又可以反过来影响糖尿病患者的血糖水平。有研究显示,糖尿病患者最佳睡眠时间为8小时。同时糖尿病患者中睡眠呼吸暂停综合征(OSAS)患病率高,0SA... 相似文献

引入数量比较信息,采用移动窗口阅读技术对文本阅读中推理的过程与内容进行研究。实验1探讨当文本阅读中存在数量比较信息时,是否能够进行即时整合,实验2和实验3分别探讨了数量比较信息即时整合的过程与内容。结果发现:当文本阅读中存在数量比较信息时,读者能够进行即时的信息整合,这种整合是自下而上的,支持记忆基础文本加工理论,如果时间足够,这种整合能够达到量化程度。 相似文献

This experiment investigated the role of context in the expression of conditioned flavour preferences. Rats were trained on a mixture of almond and sucrose and were then given intermixed exposures to almond in one context (Context A) and to sucrose in a second context (Context S). Finally, choice tests were given in both contexts, with one group given almond-versus-water tests and the other almond + sucrose-versus-sucrose tests. Preference for almond over water was greater in Context A than in Context S. Conversely, preference for almond + sucrose over sucrose was greater in Context S than in Context A. These results suggest that the perceived sweetness of a flavour depends on the context in which it is presented and confirm that expression of a flavour preference depends on the type of test employed. 相似文献

Two outlined geometric figures, an equilateral triangle and a circle, of equal contour length, were randomly presented at a fixed position in the lower or upper part of the visual field (LVF and UVF). Transient visual evoked potentials (VEPs) were recorded monopolarly from the inion (I), 5, 10, 15 cm above it (I5, I10, I15) and Fz, for 12 subjects. Grand-averaged VEPs were computed. A negative (N) wave (averaged peak latency 155 ms) was identified in the LVF and a positive (P) wave (130 ms) in the UVF. In the LVF, the N amplitude of the triangle was significantly larger than that of the circle at I5 and I. Regarding the P wave in the UVF, the triangle was of a significantly longer latency than the circle at I15, I10 and I5. The enhancement of the N amplitude for the triangle in the LVF is not attributable to the arousal caused by the preparatory state for the figure, since the subject could not predict the figure to be presented next or its position. 相似文献

不确定性风险选择的抱负水平—相对效用整合理论 总被引:2,自引:0,他引:2
本文认为不确定性风险决策备择方案的选择标准既不是规范效用理论所主张的效用最大化,也不只是研究者们基于西蒙有限理性决策理论而提出的抱负水平,而是存在于决策不同阶段上的、由启发式策略控制着的这两种标准的整合,我们称之为抱负水平-相对效用整合标准。为此,我们在研究抱负水平结构的基础上提出了负险选择的抱负水平-相对效用整合理论及其支持性研究证据,并就有关问题进行了讨论与思考。指出抱负水平-相对效用整合是风 相似文献

The biomotometer, an electronic device that simultaneously measures activity and provides auditory feedback to the subject, was used in combination with material reinforcers in two experiments attempting to modify activity level in children. In the first study the activity level of an 11-year-old highly active boy was decreased below mean baseline during conditioning in a classroom setting. His level of activity returned to baseline when feedback was withdrawn. In the second study, activity level of a 10-year-old hypoactive boy was increased over mean baseline level during conditioning in a free-play setting, and returned to slightly below baseline during five extinction trials. Results of these studies indicate that the biomotometer is a useful instrument for modification of activity level. 相似文献

On distractor-identification tests students mark as many distractors as possible on each test item. A grading scale is developed for this type testing. The scale is optimal in that it is the unique scale giving an unbiased estimate of the student's true score, i.e., the score that would result if no guessing occurred. If the test is administered as a usual multiple choice test and graded using the usual correction for guessing scale, the expected item score is the same as for the distractor-identification testing using the optimal grading scale. However, the variance of the item score is shown to be less for distractor-identification testing than for usual multiple choice testing under certain conditions. 相似文献

This study assessed the relationship between sensation seeking measured as a trait variable and drinking behaviors observed unobtrusively in the laboratory. It was hypothesized that high-sensation-seeking subjects would consume more alcohol than low sensation seekers and experience greater enhancement of positive moods and body sensations associated with intoxication. Thirty female and 31 male subjects divided into high- and low-sensation-seeking subgroups participated in an ad libitum drinking situation with the manifest task of taste rating three types of vodka (actually 95% alcohol) or tonic. Dependent variables included beverage consumption, positive/negative mood states, body sensations, breath estimates of blood alcohol levels, and self-rated level of intoxication. All subjects reported feeling the effects of alcohol. Contrary to predictions, high-sensation-seeking subjects neither consumed more alcohol than their low-sensation-seeking counterparts nor drank more alcohol than tonic, Paradoxically, low-sensation-seeking women displayed significantly greater alcohol intake and intoxication than all other groups. Possible explanations for findings were considered as well as the necessity for multimethod assessments of both predictor (i.e., sensation seeking) and criterion (i.e., alcohol consumption) variables across time and situations.This research was supported by Grant Award AA04042-03 from the National Institute on Alcohol Abuse and Alcoholism to the first and third authors. Special Appreciation is expressed to Anne T. Patsiokas, Susan W. Altman, Victoria Molony-Sinnott, and Pamela J. Thompson for their invaluable assistance in collecting and analyzing the data. 相似文献

Poverty impedes children's executive function (EF). Therefore, it is necessary to mitigate the negative effect of poverty by developing efficient interventions to improve poor children's cognitive function. In three studies, we examined whether high-level construals can improve EF among poor children in China. In Study 1, we observed a positive relationship between family socioeconomic status and children's EF, which was moderated by construal level (n = 206; Mage = 9.71; 45.6% girls). In Study 2a, we experimentally induced high- versus low-level construals and found that poor children with high-level construals exhibited better EF than those with low-level construals (n = 65; Mage = 11.32; 47.7% girls). However, the same intervention did not affect the performance of affluent children in Study 2b (n = 63; Mage = 10.54; 54% girls). Moreover, we found that the interventional effects of high-level construals improved the ability of children living in poverty to make healthy decisions and delayed gratification in Study 3 (n = 74; Mage = 11.10; 45.9% girls). These findings may have implications for using high-level construals as an effective intervention to improve poor children's EF and cognitive capacity. 相似文献
