Fictions of the internal object

This paper examines internal objects in their role as theoretical constructs which analysts use to make sense of human experience. Object relations theory is based upon a vision that the personality is divided or split into parts. Clinical experience reveals that such splits are commonly expressed in the language of our analysing. However, a lexical reality is not a thing-in-itself, but a way of organizing and understanding experience. Jung's vision of the dynamics of the split self encompass a unique 'object relations theory' that is both similar and yet quite different from the object relations theories of Klein, Fairbairn, Winnicott and Thomas Ogden A clinical example is used to examine the way in which these different theoretical views explain the same clinical phenomenon. The last section of the paper is devoted to a narrational analysis of the place of internal objects in analytic theory. The split self, dynamic is seen as a narrative device - one that makes sense and provides coherence, but is neither the only view of psychic reality nor necessarily an accurate reflection of the nature of the internal world.     

Application of the bootstrap methods in factor analysis

A Monte Carlo experiment is conducted to investigate the performance of the bootstrap methods in normal theory maximum likelihood factor analysis both when the distributional assumption is satisfied and unsatisfied. The parameters and their functions of interest include unrotated loadings, analytically rotated loadings, and unique variances. The results reveal that (a) bootstrap bias estimation performs sometimes poorly for factor loadings and nonstandardized unique variances; (b) bootstrap variance estimation performs well even when the distributional assumption is violated; (c) bootstrap confidence intervals based on the Studentized statistics are recommended; (d) if structural hypothesis about the population covariance matrix is taken into account then the bootstrap distribution of the normal theory likelihood ratio test statistic is close to the corresponding sampling distribution with slightly heavier right tail.This study was carried out in part under the ISM cooperative research program (91-ISM · CRP-85, 92-ISM · CRP-102). The authors would like to thank the editor and three reviewers for their helpful comments and suggestions which improved the quality of this paper considerably.     

护士职业的人格特质研究

采用Ｙ－Ｇ性格测验问卷,对临床护士和在读护生共３９０人,进行了心理测评,展开了护士职业的人格特质研究。研究结果表明：优秀护士群体的性格类型和某些人格特质显著地优于一般护士群体;优秀护士与一般护士间所显现出显著差异的人格特质,对于护士角色人格的构成具有决定性影响;Ｙ－Ｇ性格测验的Ａ型性格类型评定对于护士职业的心理选拔显现特异性趋势;整个测评研究结果,基本支持＂护士个体人格特质与角色人格特质的匹配模式＂等理论假设．     

Infants' sensitivity to arbitrary object-odor pairings

The ability of 4-month-old infants to learn the arbitrary relationship between an object and a distinctive odor was assessed. Infants were familiarized with two objects while one of them was paired with a cherry odor. Results indicated that only female subjects showed evidence of matching. They increased their looking to the target object in the presence of the odor but not in the absence of the odor, relative to baseline levels.     

The percentage bend correlation coefficient

A well-known result is that the usual correlation coefficient,, is highly nonrobust: very slight changes in only one of the marginal distributions can alter by a substantial amount. There are a variety of methods for correcting this problem. This paper identifies one particular method which is useful in psychometrics and provides a simple test for independence. It is not recommended that the new test replace the usual test ofH ₀: = 0, but the new test has important advantages over the usual test in terms of both Type I errors and power.     

Identification of inconsistent variates in factor analysis

When some of observed variates do not conform to the model under consideration, they will have a serious effect on the results of statistical analysis. In factor analysis the model with inconsistent variates may result in improper solutions. In this article a useful method for identifying a variate as inconsistent is proposed in factor analysis. The procedure is based on the likelihood principle. Several statistical properties such as the effect of misspecified hypotheses, the problem of multiple comparisons, and robustness to violation of distributional assumptions are investigated. The procedure is illustrated by some examples.     

三种心理测量理论的信度观

目前,心理测量领域中主要存在三大理论派别。本文分别对这三种理论即经典测验理论、可概括性理论和项目反应理论作了简要介绍,着重分析这三种理论的信度观。文章讨论了这三种信度观的理论基础和研究方法,比较了它们的异同,指出经典测验理论存在的一些不足及概化理论和项目反应理论所作的改进。概化理论是对经典测验理论的扩展,它用多维的信度指标（概化系数）替代了经典测验理论的信度系数,项目反应理论则从信息量的角度出发,用项目信息函数、测验信息函数等指标更具体深入地反映项目、测验的测量可靠程度。     

Is Speech Arrest during Wada Testing a Valid Method for Determining Hemispheric Representation of Language?

Background and objective: The intracarotid amobarbital procedure, or Wada test, is the method of choice to determine hemispheric representation of language, and is routinely used in the presurgical evaluation for intractable epilepsy. Some investigators perform comprehensive language assessments, but others base language lateralization solely on speech arrest. This study sought to determine whether speech arrest alone during Wada testing provides valid data regarding language lateralization. Methods: The subjects (previously reported) were 21 patients evaluated for intractable epilepsy, who underwent language lateralization by Wada testing and functional MRI (FMRI). For each patient, language representation was determined by calculating: (1) a Wada laterality index based exclusively on speech arrest; (2) a Wada laterality index based on comprehensive language assessment; and (3) an FMRI laterality quotient. Correlation coefficients and categorical classifications were analyzed. Results: There was no significant correlation between the Wada laterality quotient derived from duration of speech arrest and either the comprehensive Wada language laterality score (r= .35,p= .12) or FMRI language laterality score (r= .32,p= .16). Categorical classification as left, right or bilateral language also showed marked discordance between speech arrest and the other two methods. Conclusion: Duration of speech arrest during Wada testing is not a valid measure of language dominance.
