In item response theory, modelling the item response times in addition to the item responses may improve the detection of possible between- and within-subject differences in the process that resulted in the responses. For instance, if respondents rely on rapid guessing on some items but not on all, the joint distribution of the responses and response times will be a multivariate within-subject mixture distribution. Suitable parametric methods to detect these within-subject differences have been proposed. In these approaches, a distribution needs to be assumed for the within-class response times. In this paper, it is demonstrated that these parametric within-subject approaches may produce false positives and biased parameter estimates if the assumption concerning the response time distribution is violated. A semi-parametric approach is proposed which resorts to categorized response times. This approach is shown to hardly produce false positives and parameter bias. In addition, the semi-parametric approach results in approximately the same power as the parametric approach. 相似文献

An efficient and accurate numerical approximation methodology useful for obtaining the observed information matrix and subsequent asymptotic covariance matrix when fitting models with the EM algorithm is presented. The numerical approximation approach is compared to existing algorithms intended for the same purpose, and the computational benefits and accuracy of this new approach are highlighted. Instructive and real-world examples are included to demonstrate the methodology concretely, properties of the estimator are discussed in detail, and a Monte Carlo simulation study is included to investigate the behaviour of a multi-parameter item response theory model using three competing finite-difference algorithms. 相似文献

This article discusses the role played by Konrad Raiser in the World Council of Churches (WCC), from 1969, when he joined the staff as a study secretary, to his time as general secretary from 1993 to 2003, and especially his role in the conciliar process for Justice, Peace, and the Integrity of Creation. As general secretary, Raiser played a key role in supporting and encouraging the churches' witness for peace and nonviolence, strengthening the fellowship of churches within the WCC through the process to develop a “Common Understanding and Vision” and the Special Commission on Orthodox Participation in the WCC. 相似文献

Response interruption and redirection (RIRD) is a common treatment for automatically reinforced vocal stereotypy; it involves the contingent presentation of task instructions. Tasks that are included in RIRD are typically selected based on caregiver report, which may affect the efficacy of RIRD. The purpose of the current study was to evaluate the role of task preference in the efficacy of RIRD for four participants who engaged in vocal stereotypy. We conducted task-preference assessments and selected tasks of varying preferences to include in RIRD. For three out of four participants, the results showed that RIRD with higher preference tasks was not effective at reducing vocal stereotypy, whereas RIRD with lower preference tasks was effective for all participants. 相似文献

The present study examined the roles of word concreteness and word valence in the immediate serial recall task. Emotion words (e.g. happy) were used to investigate these effects. Participants completed study-test trials with 7-item study lists consisting of positive or negative words with either high or low concreteness (Experiments 1 and 2) and neutral (i.e. non-emotion) words with either high or low concreteness (Experiment 2). In serial recall performance, we replicated the typical item concreteness effect (concrete words are better recalled than abstract words) and obtained an item valence effect (positive/neutral words are better recalled than negative words). However, there was no concreteness × valence interaction. We conclude that both word valence and word concreteness independently contribute to the serial order retention of emotion words in the immediate serial recall task. 相似文献

In commemoration of Dr. Aaron T. Beck’s enormous contributions to our field, I comment on the state of our knowledge regarding the role of homework in cognitive behavioral therapy. The available evidence suggests homework is a contributor to positive therapeutic outcomes in cognitive behavioral therapy. Although therapists play an important role in facilitating clients’ engagement with homework as they develop greater facility with CBT skills, little is known about the contributions of specific approaches to promoting homework engagement. I highlight some of these strategies and discuss the need for researchers to empirically evaluate them. 相似文献

A strong therapeutic relationship provides the optimal context for CBT, and an important component of this relationship is the alliance. An alliance rupture is a difficulty or deterioration in the alliance manifested by a lack of collaboration on therapy tasks or goals or a strain in the bond. The process of rupture repair can facilitate the work of therapy by renewing collaboration and strengthening the bond. Rupture repair can also provide the opportunity for a corrective experience of successfully navigating interpersonal conflict. A review of research on rupture repair in CBT treatments highlights that ruptures are common, and that failure to repair ruptures is associated with poor outcome and premature dropout. Therapists can reduce the likelihood of contributing to ruptures by adhering to the principle of collaborative empiricism. Therapists can facilitate rupture repair by recognizing ruptures when they occur and employing repair strategies: immediate repair strategies such as modifying the treatment task, or expressive repair strategies such as metacommunicating about the rupture and exploring the interpersonal schemas that underlie it. Training in rupture repair has demonstrated benefits for CBT therapists, particularly trainees. 相似文献

习得知识的意识觉知问题一直以来是内隐学习领域的研究热点和难点。以加工分离程序来分解击中率和虚报率、以结构知识中意识和无意识测量为视角,采用2(测验方式:SDTT,SKT)×2(学习程度:30试次,60试次)混合设计,试图去分离人工语法学习中习得的意识知识和无意识知识。结果发现:(1)学习程度影响到习得的无意识知识,但还未影响到习得的意识知识;(2)在分离人工语法学习的习得知识上,SDTT的敏感性高于SKT;(3)SKT夸大了元认知中的意识成分。 相似文献

ObjectiveThe objective of this study was to examine the psychometric properties of a French version of the pictorial scale of Perceived Movement Skill Competence for Young Children (PMSC), which is aligned with the third version of the Test of Gross Motor Development.MethodA sample of 219 French-speaking Canadian children (5 to 12 years old) participated in this study.ResultsResults supported the factor validity and reliability of a 13-item version of the PMSC encompassing two factors (i.e., ball skills and locomotor skills). Subsequent analyses supported the weak, partial strong, and partial strict invariance of responses to the PMSC as a function of sex. Additionally, analyses revealed that boys displayed significantly higher perceived ball skill competence than girls. Results also supported a lack of differential item functioning (DIF) and latent mean differences as a function of body mass index and physical activity/sport involvement, but revealed evidence of DIF and latent mean differences as a function of age. More precisely, these results show that older children displayed significantly: (a) higher scores on the sliding item and lower scores on the kicking item relative to younger children; and (b) lower scores on perceived locomotor skills competence than younger children.ConclusionOverall, results suggest that the French version of the PMSC has acceptable psychometric properties and can be confidently used in research or practice to assess children's perceived movement skill competence. 相似文献
