采用同伴提名、同伴侵害问卷、不良同伴问卷和饮酒行为问卷调查广东地区4所普通初级中学1386名7年级学生,考察了同伴排斥与青少年早期饮酒行为的关系,以及同伴侵害和结交不良同伴在其中的链式中介效应。结果发现:(1)同伴排斥、同伴侵害和结交不良同伴均与青少年早期的饮酒行为呈显著正相关;(2)同伴侵害和结交不良同伴在同伴排斥影响青少年早期饮酒行为过程中的链式中介效应显著,即同伴排斥通过增加同伴侵害,从而提高结交不良同伴的风险,进而增加青少年早期的饮酒行为;(3)在控制同伴侵害和结交不良同伴后,同伴排斥对青少年早期的饮酒行为仍存在显著预测作用。 相似文献

Delay of gratification captures elements of temptation and self‐denial that characterize real‐life problems with money and other problem behaviors such as unhealthy risk taking. According to fuzzy‐trace theory, decision makers mentally represent social values such as delay of gratification in a coarse but meaningful form of memory called “gist.” Applying this theory, we developed a gist measure of delay of gratification that does not involve quantitative trade‐offs (as delay discounting does) and hypothesize that this construct explains unique variance beyond sensation seeking and inhibition in accounting for problem behaviors. Across four studies, we examine this Delay‐of‐gratification Gist Scale by using principal components analyses and evaluating convergent and divergent validity with other potentially related scales such as Future Orientation, Propensity to Plan, Time Perspectives Inventory, Spendthrift‐Tightwad, Sensation Seeking, Cognitive Reflection, Barratt Impulsiveness, and the Monetary Choice Questionnaire (delay discounting). The new 12‐item measure captured a single dimension of delay of gratification, correlated as predicted with other scales, but accounted for unique variance in predicting such outcomes as overdrawing bank accounts, substance abuse, and overall subjective well‐being. Results support a theoretical distinction between reward‐related approach motivation, including sensation seeking, and inhibitory faculties, including cognitive reflection. However, individuals' agreement with the qualitative gist of delay of gratification, as expressed in many cultural traditions, could not be reduced to such dualist distinctions nor to quantitative conceptions of delay discounting, shedding light on mechanisms of self‐control and risk taking.

采用ERP技术考察海洛因成瘾者相关线索下的用药行为的性质和神经机制, 在此基础上结合虚拟现实技术(VR)和途径偏向矫正训练(AAT), 探究基于“相关线索-习惯性用药”联结的自动化用药行为的动作消退、替代训练的有效性。研究发现, (1)相比对照线索, 成瘾者在相关线索下的反应时更长, N1波幅更小, N1潜伏期更短; 相比对照组被试, 成瘾者在相关线索下的行为任务的正确率更低, 反应时更长, N1波幅更小; N1波幅的组间组内差异和潜伏期的组内差异主要集中在中央区。(2)结合VR技术的途径偏向矫正训练后, 训练组被试的生理指标和途径偏向系数显著降低, 且显著低于对照组被试; 追踪测试中, 训练组被试的分数显著低于对照组。这表明相关线索下成瘾者的用药行为具有自动化、无意识的性质, 感觉运动区N1的异常活动是其神经机制之一。VR提取用药动作记忆-AAT消退替代训练, 可以有效削弱或消退成瘾者的成瘾动作倾向, 而且训练效果持续性较好, 可达到减少或停止现实情境中的用药和复吸行为的目的。 相似文献

以往研究探讨了父母控制与青少年问题性网络使用(PIU)的关系,但它们在父母控制的操作定义、独特效应检验、函数形式分析等方面不够完善,且较少对中介机制进行探讨。本研究考察了不同形式的父母控制(行为控制 vs. 心理控制)与青少年PIU的直接联系,以及越轨同伴交往在其中的中介效应。选取703名初中生作为被试,匿名填写人口学问卷、父母控制问卷、越轨同伴交往问卷和青少年PIU量表。回归分析表明:(1)在控制了性别、年龄和家庭社会经济地位后,父母行为控制和心理控制对青少年PIU分别具有线性的抑制效应和促进效应;(2)父母行为控制和心理控制对越轨同伴交往分别具有线性的抑制和促进效应,进而作用于青少年PIU。因此,父母行为控制和心理控制与青少年PIU具有密切的联系,且越轨同伴交往在其中具有中介效应。 相似文献

青少年疏离感与病理性互联网使用的关系:家庭功能和同伴接纳的调节效应检验 总被引:1,自引:0,他引:1
通过对549名初一至高二年级城市青少年的问卷调查, 考察了青少年病理性互联网使用的特点及其与疏离感之间的关系, 并对家庭功能和同伴接纳是否可以调节疏离感与病理性互联网使用之间的关系进行了检验。结果发现:(1)在所有使用互联网的青少年被试中, 网络成瘾群体的检出率为8.93%; (2)女青少年病理性互联网使用的突显性水平高于男青少年。在病理性互联网使用的消极后果上, 初一青少年高于高一、初三和高二青少年。但青少年病理性互联网使用总体上不存在显著的性别和年级差异; (3)疏离感较高的青少年病理性互联网使用的水平也较高, 健康的家庭功能可以保护疏离感高的青少年减少病理性互联网使用, 但同伴接纳对高疏离感青少年减少病理性互联网使用不具有保护性作用。 相似文献

Reliability of drug use responses in a longitudinal study 总被引:3,自引:0,他引:3
WILLY PEDERSEN 《Scandinavian journal of psychology》1990,31(1):28-33
In a prospective longitudinal study of adolescents' drug use, the trustfulness of the self-reports about drug use was investigated by means of a test for logical consistency. A sample of 1936 high school students completed a written survey in the fall of 1987 and again in spring 1988, seven to eight months later. The findings indicate that the information obtained is logically consistent at one particular point in time. Analyses show, however, that the consistency drops somewhat over time. The legal drug use responses show the highest consistency, the answers regarding hard drugs like amphetamine and heroin show the least favourable consistency, with cannabis and inhalants somewhere in the middle. There seem to be two main reasons for the inconsistent answers: some respondents wilfully underreport their drug consumption. This seems partly to be a function of the level of illegality of the drug. However, poor memory and episodic uses of such drugs seem also to be important. Generally this study agrees with other studies and indicates an overall relatively high level of longitudinal consistency regarding drug use responses. This kind of survey must therefore be regarded as a relatively reliable instrument in collecting information regarding drug use. 相似文献

Abstract: Chimpanzees have a large repertoire of tool-use behaviors. This study reports on the variety and the extent of tool use exhibited by the chimpanzees of the Arnhem Zoo community in The Netherlands, living in an enriched captive setting since 1971. The use of tools by 29 chimpanzees aged from 0 to 37 years was observed. We identified 13 types of tool use comparable to those found in the wild. Some of these types of tool use seem to be specific to this community, and can be explained by the ecological characteristics of this captive setting. Chimpanzees started to use tools from the age of 2 years. Young chimpanzees, from 5 to 9 years old, showed a greater repertoire of tool use than infants and adults. All types of tool use in the community have appeared by the age of 10, the age of puberty for chimpanzees. Multivariate analysis was applied for the 29 individuals by 13 types of tool use in a one-zero matrix. The results show two major categories of tool use, one in a practical or substantial context and the other in a nonpractical or play context. The subjects clustered into groups reflecting developmental stages, although there are great individual differences. In conclusion, this captive community provides a unique opportunity to clarify the details of tool use by chimpanzees. 相似文献

Conventional covariance structure analysis, such as factor analysis, is often applied to data that are obtained in a hierarchical fashion, such as siblings observed within families. A more appropriate specification is demonstrated which explicitly models the within-level and between-level covariance matrices of sibling substance use and intrafamily conflict. Participants were 267 target adolescents (mean age=13.11 years) and 318 siblings (mean age=15.03 years). The level of homogeneity within sibling clusters, and heterogeneity among families, was sufficient to conduct a multilevel covariance structure analysis (MCA). Parental and family-level variables consisting of marital status, socioeconomic status, marital discord, parent use, and modeling of substances were used to explain heterogeneity among families. Marital discord predicted intrafamily conflict, and parent marital status and modeling of substances predicted sibling substance use. Advantages and uses of hierarchical designs and conventional covariance structure software for multilevel data are discussed. 相似文献
