环境因素与成人认知关系的研究   总被引:1,自引:0,他引:1  
本研究旨在考察环境因素与认知发展的关系.采用问卷和心理测量的方法对121名21~80岁成人被试的基本认知能力和环境影响变量进行测量.结果发现,在基本认知能力上存在显著的年龄差异;在环境测量的环境维度因素方面仅出现年龄差异,而环境测量的休闲维度因素方面却存在显著的年龄和性别双重差异;多项环境因素与基本认知能力存在显著相关.结论老年人基本认知能力低于年轻被试,且环境因素对认知发展有一定影响.  相似文献

研究变异性心绞痛患者 ST 段抬高对心率变异性的影响。回顾性分析122例变异性心绞痛患者 ST 段抬高幅度及持续时间对心率变异性的影响;心率变异性与冠状动脉病变及病变支数、狭窄程度有相关性。结果心率变异性在 ST 段抬高≥0.4mv 患者中较 ST 段抬高<0.4mv 患者中明显降低(P<0.05);其在 ST 段抬高持续时间≥3min 患者中较 ST 段抬高持续时间<3min 患者中明显降低(P<0.05);其在冠状动脉狭窄≥50%患者中较冠状动脉狭窄<50%患者中明显降低(P<0.05);心率变异性在多支较单支病变明显降低(P <0.05),单支病变狭窄程度≥75%较50%~75%者明显降低(P<0.05)。提示变异性心绞痛患者自主神经系统受损程度与冠状动脉缺血严重程度,缺血持续时间密切相关,心率变异性能一定程度反映变异性心绞痛患者冠状动脉病变严重程度。  相似文献

出生缺陷是严重影响出生人口素质的重要因素之一。引起出生缺陷的因素分为遗传因素和环境因素,单纯由遗传因素或环境因素引起的出生缺陷不到其总数的1/3,另外2/3以上的出生缺陷是由遗传因素和环境因素共同作用所导致的。因此,只有不断深入研究和认识导致出生缺陷发生的原因,辩证地分析不同环境因素在出生缺陷中的作用,才能采取相应的预防和治疗措施,这对于提高出生人口素质具有十分重要的现实意义。  相似文献

该研究采用实验法,以183名大学生运动员为被试,以心率变异性为指标,在情绪诱发和认知任务的两种情况下,系统考察了不同情绪状态、不同情绪调节策略下运动员自主神经反应的特点,结果表明:情绪诱发情况下,运动员心率变异性分别受情绪状态和情绪调节策略影响.正性情绪的情绪稳定性小于负性情绪,认知重评策略更为有效;认知任务情况下,运动员心率变异性受情绪状态和情绪调节策略的共同影响.负性情绪条件下表达抑制策略的效果减弱,正性情绪条件下认知重评策略更为有效.  相似文献

本研究探讨心率变异性(HRV)特征在高水平应激条件下对神经质水平的区分力。研究选取200名被试以大五人格量表测量情绪稳定性,实施了应激诱发实验,利用光体积扫描传感器采集被试者HRV指标;利用LASSO回归分析筛选参数构建对神经质的预测模型。结果显示:模型的预测数据与神经质得分高低显著正相关;不同阶段内预测数据与神经质得分显著正相关;两两比较中实验条件阶段与其他阶段预测值差异显著。研究表明,在高应激条件下,HRV是人格神经质较好的预测指标。  相似文献

以183名运动员为被试,以心率变异性为指标,考察不同情绪状态、不同情绪调节策略下运动员自主神经反应的性别、运动年限、运动等级特点。结果发现:(1)快乐情绪状态下的心率变异性显著高于悲伤情绪状态下;表达抑制的心率变异性显著高于认知重评;短运动年限运动员的心率变异性显著高于长运动年限运动员;男性运动员的心率变异性显著高于女性运动员。(2)在快乐情绪状态下采用表达抑制策略时,低运动等级运动员的心率变异性显著高于高运动等级运动员;在悲伤情绪状态下,高运动等级运动员采用表达抑制策略比认知重评策略产生更高的心率变异性  相似文献

心率变异性在心身疾病和情绪障碍研究中的应用   总被引:6,自引:0,他引:6  
心率变异性的频谱成分可单独反映交感神经和副交感神经活动的影响。高频(HF)是由迷走神经单独介导;低频(LF)受迷走神经和交感神经共同调制,但主要反映交感神经的活动性 。此指标可对高血压、冠心病和月经前期烦躁等心身障碍进行评价。该文还探讨了它用于情绪研究的价值,并认为在不同情绪体验期间的自主神经活动有多种搭配模式,正常人与情绪障碍者之间以及情绪障碍(抑郁、焦虑、恐怖、强迫)患者在自主神经活动方面可能存在显著差别  相似文献

过敏性鼻炎和支气管哮喘是常见的上下气道联合炎性疾病.尽管其治疗手段多样,效果良好,但由于目前对过敏性鼻炎的认识及重视程度不够,治疗现状并不乐观.从哲学上辩证统一的认识过敏性鼻炎和支气管哮喘的治疗,并以现代整体医学的观点分析两者的同一性,为临床实践中针对两者进行整体治疗提供理论依据.  相似文献

A few studies have shown that untreated seasonal allergic rhinitis (hay fever) may have unfavorable effects on performance. However, prior research has employed tasks of limited or moderate difficulty (e.g., verbal learning) or has focused on visual‐motor efforts (e.g., driving a vehicle). The present research compared performance in the absence (asymptomatic) versus presence (symptomatic) of rhinitis, using the validated strategic management simulation (SMS). Obtained data indicated that whenever task‐demands were contextual (e.g., cued by the environment), no differences between symptomatic and asymptomatic conditions were obtained. Whenever task‐demands were more difficult, untreated seasonal allergic rhinitis decreased effectiveness. To avoid loss of productivity and limit decrements in quality of life, treatment of seasonal allergic rhinitis with medications without sedating effects appears of value.  相似文献

Much empirical research has examined the psychological well-being of individuals with varying gender role orientations. This research has typically shown masculinity to be a strong correlate of self-esteem and femininity to be relatively unrelated to self-esteem. This research has often failed to consider the relative environmental influences impacting this process. This study examines the relationships of masculinity and femininity to self-esteem and environmental presses for each of these sets of behavioral characteristics. Results indicate a stronger press for masculine characteristics than feminine characteristics. The person-environment interaction suggests that a masculine environment may place women who are low in masculinity at particular risk for low self-esteem. Implications for both research and practice are discussed.  相似文献

Researchers only recently have begun to examine the environmental and contextual factors that influence adolescent drinking behavior. The objective of this study was to create and test a comprehensive model of adolescent problem drinking. Items from the National Education Longitudinal Study: 1988–1994 (NELS:88; National Center for Educational Statistics, 1996) were used to create measurement models for all latent variables in the hypothesized structural model. Results indicated that high levels of parental support and a positive school climate in the 8th grade influence the formation of relationships with peers with positive values in the 10th grade that guarded against problem‐drinking behavior in the 10th grade.  相似文献

During the past few years urban fire companies have responded to a vastly increased number of false alarms, especially from lower income areas. In a preliminary attempt to understand this phenomenon, two studies were conducted. In the first, several environmental variables, in addition to average neighborhood income, reported harrassments of firemen, and type of alarm box, were correlated with false alarm frequencies for randomly selected alarm boxes in lower income sections of Brooklyn. Results of a step-wise multiple regression analysis indicated that (a) a linear combination of six environmental variables accounts for 73% of the variance in false alarms, (b) this relationship is not due simply to differences in average neighborhood income, and (c) false alarms are associated geographically with harassments. The results suggested that false alarms should be interpreted as expressions of protest. The second study explored the beliefs and attitudes of ghetto residents and revealed that young nonwhites showed most hostility to the fire department. Although most respondents expressed positive attitudes toward firemen, many believed they do unnecessary damage; and some respondents linked this with racism. Other causes for anger not directly related to the fire department were also mentioned, including the environmental factors emphasized in the first study. The findings raise several questions amenable to social psychological investigation and suggest ways to reduce false alarms, but it seems unlikely that the problem can be solved until deeper racial and class antagonisms are reduced.  相似文献
