视场亮度变化对视觉对比感受性的影响

前 言 人的视觉系统对一定视场亮度适应以后,视场亮度突然改变产生视觉的调整过程,表现为对比感受性的变化。这是生活实践中经常遇到的情形。比如,汽车司机突然从亮度较高的公路照明转向较暗的公路照明;仪表监视人员在看了暗的环境之后,突然阅读亮度高的仪表板;工厂的工人在注视了亮度高的对象之后,有时须将眼睛移向较暗的工作对象。所有上述情况对视觉感受性造成的影响,我们称为过渡适应效果。     

Counseling the Children of Handicapped Parents

The children of the handicapped frequently need counseling to help them cope with the consequences of their parents' handicaps. Parental handicaps typically lead to modifications in parenting behavior and family structure that may be perceived as deficiencies. Kennedy and Bush discuss the child's reaction to parental handicap in the context of object loss and attachment. Evidence suggests that the children of the handicapped are overrepresented among those who are in some way maladjusted or in need of counseling. This article focuses on multiple sclerosis in parents, including its impact on children, suggested interventions, and a case study.     

Divorced Parents in Family Therapy in a Residential Treatment Setting

Divorced parents are required to participate together in the family therapy of their child placed in a residential treatment center. Different sources of resistance and treatment techniques are identified and discussed through a theoretical analysis and case study material. The therapy of these fractured families contributed to an elimination of recidivism and, according to followup reports, to significant and sustained improvement in the children's functioning in school, home, and community activities.     

被动性社交网站使用与青少年体像烦恼的关系:体像比较和体像自我差异的中介作用

为探讨被动性社交网站使用和青少年体像烦恼的关系,基于社会比较理论和自我差异理论,采用被动性社交网站使用问卷、社交网站体像比较量表、理想体像问卷和体像烦恼量表,对789名初、高中生进行调查。结果表明：（1）被动性社交网站使用对青少年体像烦恼具有显著的正向预测作用;（2）体像比较和体像自我差异能在被动性社交网站使用和体像烦恼的关系中起中介作用;（3）在被动性社交网站使用与体像烦恼的关系中,女生的体像比较和体像自我差异起并行中介作用,而对男生而言,体像比较和体像自我差异起链式中介作用。研究结果表明被动性社交网站使用不仅能直接影响青少年的体像烦恼,还可通过体像比较和体像自我差异的间接作用对青少年体像烦恼产生影响,且中介路径存在性别差异。
