该研究基于项目反应理论的Samejima等级反应模型(GRM),在MULTILOG软件支持下,应用参数检测方法,对某年度全国性资格考试的某科目试卷中经济法部分的21个项目做了DIF检测分析。结果如下:存在性别DIF的项目一个,存在民族DIF的项目四个,存在工作性质DIF的项目一个。其中项目68在民族层面上表现为一致性DIF,项目64既存在民族DIF又存在工作性质DIF。通过对项目统计量、反应曲线的分析和专家的讨论,文章最后还分析了产生这些DIF的几个可能的原因。     

Global and Local Feature Distinctiveness Effects in Language Acquisition

Various aspects of semantic features drive early vocabulary development, but less is known about how the global and local structure of the overall semantic feature space influences language acquisition. A feature network of English words was constructed from a large database of adult feature production norms such that edges in the network represented feature distances between words (i.e., Manhattan distances of probability distributions of features elicited for each pair of words). A word's global feature distinctiveness is measured with respect to all other words in the network and a word's local feature distinctiveness is measured relative to words in sub-networks derived from clustering analyses. This paper investigates how feature distinctiveness of individual words at local and global scales of the network influences language acquisition. Regression analyses indicate that global feature distinctiveness was associated with earlier age of acquisition ratings, and was a stronger predictor of age of acquisition than local feature distinctiveness. These results suggest that the global structure of the semantic feature network could play an important role in language acquisition, whereby globally distinctive concepts help to structure vocabulary development over the lifespan.     

Self-Concepts of Hospitalized and Day-Care Psychiatric Patients

Abstract

The authors administered questionnaires to 44 hospitalized and 55 day-care psychiatric patients in Hong Kong. The groups were similar in sex, age, and education. The hospitalized participants, compared with the day-care participants, showed significantly higher self-concepts in general as well as in the particular aspects of social and personal aspirations. The findings indicate that support at the community level is important to help the psychiatric patients' transition from hospital care to day care.     

“Hit Me, Maybe, One More Time”: Brief measures of impulsivity and sensation seeking and their prediction of blackjack bets and sexual promiscuity

We sought to construct an efficient, reliable, and valid self-report measure of impulsivity and sensation-seeking. We used item response theory to identify the 8 best items (ImpSS-8) from the 19-item Impulsivity and Sensation-Seeking Scale (Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993; Study 1). The ImpSS-8 interacted with a manipulated ego threat to predict blackjack bets: in a weak situation (no ego threat), individual differences were strong (a positive ImpSS-8-bets relationship); in a strong situation (ego threat), individual differences were weak (no relationship; Study 2). The ImpSS-8’s 4-item impulsivity and sensation-seeking subscales related differentially to the Balloon Analogue Risk Task (Study 2) as well as trait measures of openness and conscientiousness, hostility and physical aggression, and sexually promiscuous attitudes and timing (Study 3).     

Psycholinguistic variables involved in concept recall from the successive presentation of features / Variables psicolingüísticas involucradas en la evocación de conceptos a partir de la presentación de atributos sucesivos

Abstract

The aim of this study was to analyse the psycholinguistic variables of the attributes and concepts involved in the recall of a concept. One hundred and twenty adults (18–40 years old) participated. A lexical recall task was administered by presenting a successive list of defining attributes. Forty concepts from different semantic categories were used. The attributes were obtained empirically from local Semantic Features Production Norms. The influence of the characteristics and attributes of the concepts on the number of participants who accessed the name of the concept and the correct guess trend was analysed. Significant values for Age of Acquisition, Presence of Distinctive Attributes and Presence of Taxonomic Attributes were observed. Results show that concepts which are acquired earliest are more easily recalled; presenting taxonomic categories narrows the search and the presence of distinctive attributes allow differentiating between such concepts within a category.     

二参数逻辑斯蒂模型项目参数的估计精度

项目参数的估计精度对于测验的编制尤其是题库的建立十分重要。目前,国内外对项目参数估计精度的研究,大部分是基于在已知项目参数真值的情况下,运用各种参数估计方法产生新的估计值,再和真值进行偏度(BIAS)和均方根差(RMSE)的比较,从而说明该种估计方法的有效性。但是这种方法不能提供不同的参数真值之间的估计误差的变化规律。为了弥补这一缺陷,本文尝试从项目参数估计信息函数的角度出发研究项目参数的估计精度问题。本研究以二参数Logistic模型作为研究对象,首先定义了项目参数的估计信息函数,然后基于完全随机实验设计,通过模拟研究的方法探索影响项目参数的估计精度的因素,实验共设计了(2×3×2)种情形。研究结果表明：(1)项目参数(a,b)的估计精度均随着被试样本量的增大而提高;(2)被试的能力分布对难度参数的估计精度影响较大,对区分度参数的估计精度影响相对较小;(3)难度参数和区分度参数的估计精度都分别受到参数a和参数b的共同作用。     

Directed forgetting of complex pictures in an item method paradigm

An item-cued directed forgetting paradigm was used to investigate the ability to control episodic memory and selectively encode complex coloured pictures. A series of photographs was presented to 21 participants who were instructed to either remember or forget each picture after it was presented. Memory performance was later tested with a recognition task where all presented items had to be retrieved, regardless of the initial instructions. A directed forgetting effect—that is, better recognition of “to-be-remembered” than of “to-be-forgotten” pictures—was observed, although its size was smaller than previously reported for words or line drawings. The magnitude of the directed forgetting effect correlated negatively with participants’ depression and dissociation scores. The results indicate that, at least in an item method, directed forgetting occurs for complex pictures as well as words and simple line drawings. Furthermore, people with higher levels of dissociative or depressive symptoms exhibit altered memory encoding patterns.     

A Factorial Analysis of Responses to the Comic as a Study in Personality

Modeling techniques were used to model moderate disclosure to high and low disclosers. Eighty female undergraduates (40 low disclosers and 40 high disclosers) listened to a model select items that were rated as moderate disclosures for discussion. Two modeling conditions were employed; in one condition the model was reinforced by the E (vicarious reinforcement), in the second condition the model was not reinforced. Two control conditions, one with the model present, the other with the model absent were also included. The results of two separate 2 × 4 × 2 repeated measures, hierarchical analyses of variance on the subject distance from modeled intimacy, and the number of moderate items selected on pre- and posttests, indicated that both modeling conditions were successful in producing moderation of self-disclosure.     

Evolutionary Perspectives and Transdisciplinary Intersections: A Roadmap to Generative Areas of Overlap in Discussing Human Nature

This essay assesses a subset of approaches to the topic of human nature(s) and endeavors to identify generative areas of overlap for transdisciplinary conversation. Rather than pursue a resolution to the problem of potentially incompatible frameworks across perspectives, I seek to provide a template, or a roadmap, for a better conversation. My conclusions derive from a targeted literature assessment of subareas within the disciplines of philosophy, biology, anthropology, psychology, and theology, emphasizing those open to evolutionary contexts. I highlight eighteen core elements/themes and propose a few central thematic clusters as foci for moving the exchange on human nature between theology and science forward.
