人格的生理基础研究综述

从生理基础来解释人格的产生,是人格研究的重要方面。随着脑科学技术等研究方法的进展,西方心理学家越来越重视这个途径,而国内对此的介绍和研究很少。该文对人格的生理基础研究进行了综述,重点从体型、神经类型和生理节律、脑中枢定位及神经递质四个层面介绍了八种主要理论。     

自传体广告优势效应的实验研究

自传体广告能够唤起消费者对产品或品牌的某些以往记忆,它会影响人们对广告信息的加工方式,同时更为重要的是它能够改变人们的认知。在营销实战和研究中,都备受关注。本研究试图通过两个实验探讨它的内在机制,以及与事实性广告相比,在感知觉、情绪情感、认知改变等方面的优势。结果发现自传体广告确实在感知觉、情绪情感、认知改变等方面具有优势效应。此外还发现了自传体广告的特异性。     

The gender paradigm in domestic violence research and theory: Part 1—The conflict of theory and data

Feminist theory of intimate violence is critically reviewed in the light of data from numerous incidence studies reporting levels of violence by female perpetrators higher than those reported for males, particularly in younger age samples. A critical analysis of the methodology of these studies is made with particular reference to the Conflict Tactics Scale developed and utilised by Straus and his colleagues. Results show that the gender disparity in injuries from domestic violence is less than originally portrayed by feminist theory. Studies are also reviewed indicating high levels of unilateral intimate violence by females to both males and females. Males appear to report their own victimization less than females do and to not view female violence against them as a crime. Hence, they differentially under-report being victimized by partners on crime victim surveys. It is concluded that feminist theory is contradicted by these findings and that the call for “qualitative” studies by feminists is really a means of avoiding this conclusion. A case is made for a paradigm having developed amongst family violence activists and researchers that precludes the notion of female violence, trivializes injuries to males and maintains a monolithic view of a complex social problem.     

毒扁豆碱对吗啡导致的大鼠行为敏感化的抑制作用

药物滥用导致的行为敏感化被认为与成瘾过程密切相关。本实验探讨吗啡导致的大鼠行为敏感化与神经递质乙酰胆碱的关系。实验动物分为3组,分别进行生理盐水、吗啡（10.0mg/kg）、吗啡（10.0mg/kg）＋胆碱酯酶抑制剂毒扁豆碱（0.2mg/kg）前处理,36小时腹腔注射4次。前处理结束1周所有动物注射小剂量吗啡（4.0mg/kg）;使用生理盐水前处理的动物,第2周注射毒扁豆碱（0.2mg/kg）;使用吗啡前处理的动物,第2周注射小剂量吗啡＋毒扁豆碱（0.2mg/kg）,第3周再次注射小剂量吗啡。动物每次接受注射后立即记录其在两小时内的活动量(10分钟为一个记录单元)。结果表明,毒扁豆碱既能够抑制吗啡诱导的行为敏感化,也能够阻断小剂量吗啡对行为敏感化的“点燃”作用。由此推论,吗啡导致的行为敏感化与其抑制乙酰胆碱分泌有关。     

从儿童赌博任务看热执行功能的发展

为考察热执行功能的发展,本研究通过儿童赌博任务检测了60名3～4岁儿童(男女各半)的情感决策。实验结果表明,3岁和4岁儿童在此任务上存在显著的年龄差异,4岁组在各试验组的分数呈上升趋势,他们在试验组2、尤其在试验组4和5中选择有利纸牌的次数显著多于3岁儿童,这反映出情感决策在3～4岁期间发展迅速。此外,儿童在此任务上的成绩存在很多可变性,可能掩盖了性别差异,因而,尽管男孩在最后两个试验组的成绩优于女孩,但性别差异在统计上并不显著。     

凋亡--一个令人困惑的名称

就"细胞凋亡"这个热点名称进行探讨,从凋亡的起因及定义、由凋亡定义引起的哲学思考及就定义所做的建议进行分别论述.凋亡最初提出的是一种形态学特点,描述与坏死相对应的细胞解体的主动过程,之后大多数文章把凋亡定义为程序性的细胞死亡,并逐步演绎把死亡之前的细胞内生化变化称为凋亡.由此引起凋亡判断标准的混乱,并产生相关的药理学问题.细胞凋亡的实际情况与人类冠以的定义产生矛盾,其根本原因是真正实体与人为定义概念的哲学思维的混淆.提出应用直接描述真正实体的名称较凋亡更为可取.     

Response to commentary on the multimodal treatment study of ADHD (MTA): mining the meaning of the MTA

In the December 2000 issue of the Journal of Abnormal Child Psychology, we published a set of papers presenting secondary analyses of the Multimodal Treatment Study of ADHD (MTA), and R. A. Barkley (2000) provided a commentary. A critique of the design of the study (MTA Cooperative Group, 1999) was presented based on a theoretical perspective of a behavioral inhibition deficit that has been hypothesized as the core deficit of ADHD (R. A. Barkley, 1997). The commentary questioned the design and analysis of the MTA in terms of (1) the empirical criteria for selection of components of behavioral (Beh) intervention, (2) the effectiveness of the Beh intervention, (3) the methods for analyses at the group and individual level, (4) implications of the MTA findings for clinical practice, (5) the role of genetics in response to treatment, and (6) the lack of a nontreatment control group. In this response, we relate the content of the papers to the commentary, (1) by reviewing the selection criteria for the Beh treatment, as outlined by K. C. Wells, W. E. Pelham, et al. (2000), (2) by addressing the myth that the MTA Beh treatment was ineffective (Pelham, 1999), (3) by describing the use of analyses at the level of the individual participant, as presented by J. S. March et al. (2000) and W. E. Pelham et al. (2000) as well as elsewhere by J. M. Swanson et al. (2001) and C. K. Conners et al. (2001), (4) by relating some of the suggestions from the secondary analyses about clinically relevant factors such as comorbidity (as presented by J. S. March et al., 2000) and family and parental characteristics (as presented by B. Hoza et al., 2000, S. P. Hinshaw et al., 2000, and K. C. Wells, J. N. Epstein, et al., 2000), (5) by discussing the statistical concept of heritability and the lack of a significant difference in the presence of ADHD symptoms in parents of the MTA families compared to parents in the classmate-control families (as presented by J. N. Epstein, et al., 2000), and (6) by acknowledging that an ethically necessary weakness of the MTA design is that it did not include a no-treatment control group. We discuss the use of secondary analyses to suggest how, when, and for what subgroups effectiveness of the Beh treatment may have been manifested. Finally, we invite others to use the large and rich data set that will soon be available in the public domain, to perform secondary analyses to mine the meaning of the MTA and to evaluate theories of ADHD and response to treatments.     

Comparative differences in the self-perceptions of disadvantaged and advantaged students

Previous research had indicated positive and significantly higher self-perceptions for disadvantaged children in comparison to advantaged children in grades four through eight. The intention of this research was to determine whether disadvantaged children maintain their more positive self-images when they enter the more integrated environment with advantaged children. It was discovered that both disadvantaged and advantaged high school students had significantly lower self-perception scores than did the elementary school pupils. The importance of the study is in the continued non-support of the hypothesis that disadvantaged children of all ages have negative self concepts—whether in segregated or integrated situations. However, the study further shows that high school students' self-images are not as high as those of younger children—whether they are disadvantaged or advantaged.     

Variations in the intelligence test performance of referred boys of differing racial and socioeconomic backgrounds as a function of feedback or monetary reinforcement

One hundred fifty-six elementary school males referred to school psychologists were characterized as lower-class whites, lower-class Negroes, or middle-class whites. Each of these groups was tested with the verbal scale of the WISC under either standardized conditions, feedback concerning correct answers, or contingent monetary reinforcement for correct answers. Middle-class whites and lower-class Negroes did not differ across treatments. However, lower-class whites tested under feedback or monetary conditions performed significantly better than lower-class whites tested under standardized conditions. Implications for testing procedures or the interpretation of test scores were evident.     

Use of the Peabody Picture Vocabulary Test with the educationally handicapped

Despite widespread use of the Peabody Picture Vocabulary Test (PPVT) as a measure of intelligence for educationally handicapped students, few studies have related PPVT scores of such students to their scores on the Wechsler Intelligence Scale for Children (WISC). Using 100 public school students consecutively referred for learning difficulties, their mean PPVT IQ (97.75) was found to be consistently and significantly higher than WISC Full Scale IQ (89.65), Verbal IQ (88.68), and Performance IQ (92.73). Correlations between the PPVT IQ and the WISC Full Scale, Verbal, and Performance IQs were .70, .69, and .54, respectively. A tabular summary of previous studies comparing PPVT and WISC IQs is included.
