当前人格心理学研究中存在的问题与对策 总被引:1,自引:0,他引:1
人格心理学立足于整体性与差异性以揭示个体行为规律与内部作用机制,是心理学中极富特色的研究领域,并彰显出旺盛的发展势头。但由于人格现象本身的宽泛性与复杂性,当前该领域存在诸多纷争与问题。该文从四个方面剖析了人格心理学面临的主要问题,并提出相应的发展建议与对策。 相似文献

ABSTRACTThe basic mechanisms governing the process of cracking of single-layer brittle films have been extensively explored through both simulations and experiments. However, the role that an adhesive interlayer plays in the cracking of the overlying brittle film remains unclear. By performing three-point bending experiments, we observed that the insertion of a 100?nm thick Ti interlayer changed the cracking behaviour of TiN films from a continuous pattern to a discontinuous pattern. The slight change in the microstructure of the film and the increase in film thickness arising from the addition of the Ti interlayer are unlikely to cause the observed cracking morphology. The combination of the different interface between the Ti and the steel substrate and the fracture of the Ti interlayer are responsible for the transition in the TiN film cracking morphologies. 相似文献

中国科学心理学是在20世纪初复杂的社会背景下通过传入西方心理学而建立和发展起来的.在这一过程中,心理学图书的出版和传播起到了重要作用.文章以《民国时期总书目》中收录的心理学图书为研究对象,通过对心理学图书的年出版量、编著与译著的比较、出版数量的地域差异、分支学科的出版特征等四个方面的出版状况进行计量分析,探讨其形成原因和历史背景,试图从出版视角对民国时期科学心理学在中国的发展做微观的历史考察. 相似文献

采用内隐联想测验(Implicit Association Test简称IAT)对不同类网络信息态度进行测量和研究。结果显示,无论是词汇测验还是图片测验,相容联结的平均反应时均小于不相容联结平均反应时,且差异显著。结论:(1)人们对于不同类的网络信息有一定的偏好,产生了IAT效应;(2)与政策信息相比,被试对娱乐信息的形式和内容(即实验中所采用的截图与词语)都表现出显著的偏好;(3)在内隐社会认知领域,存在对娱乐信息的偏好,且男女之间无性别差异。 相似文献

This paper extends the self-categorisation model of symptom perception to predict that people aged 50 years and over will report higher levels of hearing handicap when they categorise themselves as members of a group of older people. This prediction is supported with an opportunity sample ( N = 50; mean age = 63 years) who completed a questionnaire designed to screen for hearing handicap in "the elderly" ( sic ). Participants also underwent pure-tone audiometry, which confirmed that the observed difference in hearing handicap was not attributable to any difference in hearing threshold level. Hence these findings offer further support for the self-categorisation model of symptom perception. Their theoretical, clinical, and methodological implications together with possible therapeutic applications of self-categorisation theory to auditory rehabilitation of older people are discussed. 相似文献

The Strengths and Difficulties Questionnaire (SDQ) is one of the most commonly used instruments for screening psychopathology in children and adolescents. This study evaluated the hypothesized five-factor structure of the SDQ and examined its convergent validity against comprehensive clinical diagnostic assessments. Data were derived from the National Comorbidity Survey - Adolescent Supplement (NCS-A), a nationally representative sample of U.S. adolescents aged 13 to 18 years. Parents/parent surrogates (n=6,483) was asked to complete a self-administered questionnaire including the SDQ and DSM-IV comprehensive diagnostic information on the participating adolescents. Confirmatory factor analysis (CFA) was conducted to assess the factor structure of the SDQ. The five-factor solution of the SDQ (including emotional, conduct, hyperactivity-inattention, peer relationship, and prosocial) provided a satisfactory fit to the data, and was invariant across sex, age, race/ethnicity and income subgroups. SDQ scores predicted a significantly increased probability of meeting criteria for a DSM-IV disorder, with better prediction for behavior disorders than for mood disorders. Decreasing the SDQ cutoffs to the 80th percentile significantly increased the sensitivity from 39% to 63% for the SDQ Total Difficulties Score, with an expected decrease in specificity from 93% to 87%. This work confirms the five-factor structure of the SDQ in an ethnically and sociodemogrpahically diverse community sample of adolescents. Our findings strengthen empirical evidence for the use of the parent-reported SDQ as a screening tool for DSM-IV behavioral and emotional disorders in adolescents identified in the general population. 相似文献

The biomechanical difference between the dominant and non-dominant limb has seldom been studied during double-leg landing. The objective of this study was to evaluate the effectiveness of limb laterality on the ankle kinematics, kinetics and electromyogram (EMG) during drop landing. Sixteen healthy adults were recruited and dropped individually from platforms with three different heights (0.32 m, 0.52 m, and 0.72 m). The ground reaction force, ankle joint kinematics, and surface EMG of tibialis anterior (TA) and lateral gastrocnemius (LG) were measured in both lower extremities. Two-way analysis of variance was used to analyze the effects of laterality and dropping height. The peak angular velocities in dorsiflexion and abduction were significantly higher in the dominant ankle, whereas the pre- and post-landing EMG amplitudes of the TA were significantly higher in the non-dominant limb. Compared with the dominant side, the non-dominant ankle has a more effective protective mechanism in that excessive joint motion is restrained by greater ankle flexor activity. Compared with the non-dominant side, the dominant ankle joint is in greater injury risk during drop landing, and data measured in the dominant limb may produce more conservative conclusions for injury protection or prediction. 相似文献
