基于改进的Wald统计量,将适用于两群组的DIF检测方法拓展至多群组的项目功能差异(DIF)检验;改进的Wald统计量将分别通过计算观察信息矩阵(Obs)和经验交叉相乘信息矩阵(XPD)而得到。模拟研究探讨了此二者与传统计算方法在多个群组下的DIF检验情况,结果表明:(1)Obs和XPD的一类错误率明显低于传统方法,DINA模型估计下Obs和XPD的一类错误率接近理论水平;(2)样本量和DIF量较大时,Obs和XPD具有与传统Wald统计量大体相同的统计检验力。  相似文献

In this study, the history of psychological testing in Japan is described using the oral history method. Seven test developers discussed the development of Japanese versions of the Wechsler Intelligence Scale, Binet-Simon Intelligence Scale, and Kaufman Assessment Battery for Children. Three conclusions were identified. First, the motivation for developing the tests shifted from one of personal aspiration to a wider responsibility of specialists' desiring to make social contributions. Second, the test developers shifted from working in small, familiar, collaborative groups to working in groups of specialists conducting well-organized projects. Third, the development of tests has variously been led by researchers, publishers, researcher-and-publisher collaborations, or institutes. In addition, this study identifies contemporary challenges for developing psychological tests, specifically due to insufficient numbers of participants and test developers.  相似文献

As a core component of most cognitive diagnosis models, the Q-matrix, or item and attribute association matrix, is typically developed by domain experts, and tends to be subjective. It is critical to validate the Q-matrix empirically because a misspecified Q-matrix could result in erroneous attribute estimation. Most existing Q-matrix validation procedures are developed for dichotomous responses. However, in this paper, we propose a method to empirically detect and correct the misspecifications in the Q-matrix for graded response data based on the sequential generalized deterministic inputs, noisy ‘and’ gate (G-DINA) model. The proposed Q-matrix validation procedure is implemented in a stepwise manner based on the Wald test and an effect size measure. The feasibility of the proposed method is examined using simulation studies. Also, a set of data from the Trends in International Mathematics and Science Study (TIMSS) 2011 mathematics assessment is analysed for illustration.  相似文献

Disengaged test taking tends to be most prevalent with low-stakes tests. This has led to questions about the validity of aggregated scores from large-scale international assessments such as PISA and TIMSS, as previous research has found a meaningful correlation between the mean engagement and mean performance of countries. The current study, using data from the computer-based version of the PISA-Based Test for Schools, examined the distortive effects of differential engagement on aggregated school-level scores. The results showed that, although there was considerable differential engagement among schools, the school means were highly stable due to two factors. First, any distortive effects of disengagement in a school were diluted by a high proportion of the students exhibiting no non-effortful behavior. Second, and most interestingly, disengagement produced both positive and negative distortion of individual student scores, which tended to cancel out much of the net distortive effect on the school’s mean.  相似文献

Accurate tests of cognition are vital in (neuro)psychology. Cancellation tasks are popular tests of attention and executive function, in which participants find and ‘cancel’ targets among distractors. Despite extensive use in neurological patients, it remains unclear whether demographic variables (that vary among patients) affect cancellation performance. Here, we describe performance in 523 healthy participants of a web-based cancellation task. Age, sex, and level of education did not affect cancellation performance in this sample. We provide norm scores for indices of spatial bias, perseverations, revisits, processing speed, and search organisation. Furthermore, a cluster analysis identified four cognitive profiles among participants, characterised by many omissions (N=18), many revisits (N=18), relatively poor search organisation (N=125), and relatively good search organisation (N=362). Thus, patient scores pertaining to search organisation should be interpreted cautiously: Given the large proportion of healthy individuals with poor search organisation, disorganised search in patients might be pre-existing rather than disorder-related.  相似文献

ABSTRACT

Aging seems to be associated with impairment of attentional network functioning. It is not known whether social information can modulate this age-related decline. We used three variants of Attention Network test to examine the age-related decline of attentional effects in response to stimuli with and without social-cognitive content. Three groups of younger, middle-aged, and older participants performed the ANT, using fish, drawings, or photographs of faces looking to the left or right as target and flanker stimuli. The results showed that both executive attention and alerting were more resistant to the age-related decline with social stimuli and that orienting attention scores showed a progressive increase with age in the presence of this kind of stimuli. These findings underline the importance of social information in modulating and contrasting the age-related decline and support the status of human faces as a special class of visual stimuli for the human attentional systems.  相似文献

This study examined the factorial structure of the Theory of Mind (ToM) Storybooks, a comprehensive 93‐item instrument tapping the five components in Wellman's model of ToM (emotion recognition, understanding of desire and beliefs, ability to distinguish between physical and mental entities, and awareness of the link between perception and knowledge). A sample of 681 three‐ to eight‐year‐old Italian children was divided into three age groups to assess whether factorial structure varied across different age ranges. Partial credit model analysis was applied to the data, leading to the empirical identification of 23 composite variables aggregating the ToM Storybooks items. Confirmatory factor analysis was then conducted on the composite variables, providing support for the theoretical model. There were partial differences in the specific composite variables making up the dimensions for each of the three age groups. A single test evaluating distinct dimensions of ToM is a valuable resource for clinical practice which may be used to define differential profiles for specific populations.  相似文献

Aggressiveness has been one of the behavioral traits most examined with various standard testing methods. We used two distinct methods (the mirror and the real opponent tests) to evaluate individual aggression and relate it to the activity and individual stress of chub (Squalius cephalus L.). Three hypotheses were formulated and tested: (a) there is a significant positive relationship between the aggressiveness of individuals measured with the mirror and the real opponent tests, indicating their convergent validity; (b) the irregularities in response to the aggressiveness and activity tests lead to the context-specific expression of the behavioral syndromes; and (c) there is a significant positive relationship between the stress induced in individuals by both tests of aggressiveness, demonstrating individually consistent stress-coping strategies. The first and the second hypothesis were confirmed, while the third hypothesis was rejected. Our results suggest that particular tests of aggressiveness could act as a situation with high strength, leaving little variation between individual responses. Thus, we propose that for the proper interpretation of various studies using different tests to study identical behavioral traits, it is important to consider the convergent validity of not only the tested behavioral traits but also the individual stress responses. The chub also showed stress relieve through aggressiveness, suggesting the species as a prospective animal model to the study interaction between the stress and the aggressiveness. A detailed aggression ethogram of chub was provided to facilitate the use of this specie in future studies.  相似文献
