自由回忆和线索回忆测验中的系列位置效应 总被引:3,自引:1,他引:2
本文以96个中国汉字为材料,使用自由回忆和线索回忆测验方法,对20名被试进行6组分测验和最后所有汉字的总测验。发现自由回忆分测验中存在明显的系列位置效应,总测验出现负近因现象;线索回忆分测验也表现出明显的系列位置效应,但最后的总测验没有出现负近因现象。上述结果验证了Bjork和Whitten(1974)提出的顺序或情景理论。 相似文献

卡车驾驶员速度估计研究 总被引:4,自引:0,他引:4
用速度知觉测试仪,对251名男性卡车驾驶员在四种实验条件下的速度估计准确性进行了测量。结果发现:安全组卡车驾驶员的速度估计准确性优于事故组卡车驾驶员,两者在低速条件下差异不显著,高速条件下差异显著;事故组卡车驾驶员的高估次数高于安全组卡车驾驶员,低速条件下两者不显著.高速条件下差异显著;事故多发组与安全组卡车驾驶员的速度估计准确性在高速及低速长距离条件下差异显著;速度及距离对速度估计准确性有显著影响,且两者之间存在显著的交互作用;年龄对速度估计准确性无显著影响。 相似文献

This paper discusses two forms of separability of item and person parameters in the context of response time (RT) models. The first is separate sufficiency: the existence of sufficient statistics for the item (person) parameters that do not depend on the person (item) parameters. The second is ranking independence: the likelihood of the item (person) ranking with respect to RTs does not depend on the person (item) parameters. For each form a theorem stating sufficient conditions, is proved. The two forms of separability are shown to include several (special cases of) models from psychometric and biometric literature. Ranking independence imposes no restrictions on the general distribution form, but on its parametrization. An estimation procedure based upon ranks and pseudolikelihood theory is discussed, as well as the relation of ranking independence to the concept of double monotonicity.I am indebted to Wim van der Linden for bringing Thissen's (1983) paper to my notice, and to Martijn Berger, Frans Tan, and the anonymous reviewers for their constructive comments on earlier drafts of this paper. 相似文献

The question asked in this study of 70 clinically referred 6- to 12-year-old boys with behavior problems was whether or not childhood inattention-overactivity and aggression are transmitted specifically from biological fathers to sons. Fathers' self-reported childhood inattention-overactivity on a retrospectively valid measure was exclusively associated with parents' ratings of their sons' current attention problems on the Mothers' Operational Measure for Sub-grouping (MOMS), the Revised Child Behavior Checklist (RCBCL), and an approximated DSM-IV inattention dimension. Fathers' self-reported childhood aggression was not associated with ratings of their sons' aggression on the MOMS or DADS (a parallel instrument for fathers), nor on DSM-III oppositional or conduct disorder dimensions, but it was exclusively associated with RCBCL ratings of sons' aggressive and delinquent behavior. None of the nonspecific correlations (father inattention-overactivity with son aggression or father aggression with son inattention-overactivity) was significant. 相似文献

The author examines the position of a child from whom important matters in his or her own life or key events in the family have been kept secret, outlines criteria by which the decision whether or not to unveil the secret should be made, and urges colleagues to gather more data and examine further family secrets. 相似文献

Immigration and remarriage are two stressful events that impact on family's functioning and well being. This article examines the effects on families of experiencing both of these transitions simultaneously. A case illustration is presented and implications for practice and for future research are discussed. The article is based on the clinical experience of the writer as well as on her study of stepfamilies from diverse cultural backgrounds. 相似文献

Although choices of required textbooks are important decisions in developing a course curriculum, faculty in marriage and family therapy training programs have few convenient resources to guide curriculum development. This article presents results of a survey of textbook selections of accredited marriage and family therapy programs within a regional affiliate of AAMFT. The five programs surveyed listed 108 different titles used in their curriculum. Only 12 texts were used by two programs, and only one text was used by more than two programs. This article presents the textbook selections by the six curricular areas of COAMFTE accreditation standards. The wide variety of textbooks used by programs leads us to conclude that no consensus exists about what textbooks best represent the core knowledge of marriage and family therapy. The body of knowledge taught in accredited marriage and family training programs reflects a distinct and autonomous body of knowledge. 相似文献

The results of a qualitative research study designed to better understand the developmental processes active in beginning therapists during the first three months of clinical contact is reported. Thirteen beginning therapists were asked to complete a monthly log describing experiences impacting their clinical work and themselves as therapists during their first three months of client contact. Data analysis revealed that the primary developmental theme active during this period of time is the development of therapist confidence. Two additional themes, the development of an internal gauge on which to evaluate current experiences and the development of boundaries around the self as a professional, were also found to be active during this time. These additional themes support the development of therapist confidence. Implications for training and research are identified. 相似文献

The thesis of this paper is that even some of the most fundamental concepts of Marxism have been used and abused to fit their advocates' purposes. More specifically, the interpretation of the concept of the "dictatorship of the proletariat" has been subject to a dual development. First, the dictatorship of the proletariat has come to denote an increasingly violent regime. Second, the term has been used to refer to a rule exercised by an ever smaller segment of society. This paper seeks to analyze and elucidate this much disputed and frequently misunderstood Marxist concept. In the first part Marx's use of the term is examined. The second section explores how the same concept was explicated in the writings of some of the most important first generation Marxist thinkers and "practitioners" like Engels, Lenin, Kautsky, Bukharin, and Stalin. Following the summary of my findings I attempt to formulate some meaningful generalizations about the usage of the concept by Marxist thinkers. 相似文献
