Non‐ignorable missingness item response theory models for choice effects in examinee‐selected items

Examinee‐selected item (ESI) design, in which examinees are required to respond to a fixed number of items in a given set, always yields incomplete data (i.e., when only the selected items are answered, data are missing for the others) that are likely non‐ignorable in likelihood inference. Standard item response theory (IRT) models become infeasible when ESI data are missing not at random (MNAR). To solve this problem, the authors propose a two‐dimensional IRT model that posits one unidimensional IRT model for observed data and another for nominal selection patterns. The two latent variables are assumed to follow a bivariate normal distribution. In this study, the mirt freeware package was adopted to estimate parameters. The authors conduct an experiment to demonstrate that ESI data are often non‐ignorable and to determine how to apply the new model to the data collected. Two follow‐up simulation studies are conducted to assess the parameter recovery of the new model and the consequences for parameter estimation of ignoring MNAR data. The results of the two simulation studies indicate good parameter recovery of the new model and poor parameter recovery when non‐ignorable missing data were mistakenly treated as ignorable.     

Maximus the Confessor and the Problem of Participation

In defining the theological problem of participation as the question of how created beings, namely human beings, can participate (μ?θεξι?) in the transcendent Uncreated God towards deification (θ?ωσι?) without a pantheistic blurring of essences, this article examines the Christologically intuitive way in which Maximus the Confessor (580–662) would have responded. Specifically, Maximus’ Cyrilline Chalcednonianism, featuring an unconfused perichoretic union between Christ's two natures in his hypostatic union, serves directly as an apologetic and hermeneutic for humanity's and creation's participation in God. In addition, taking into account the scholarly debate over Maximus’ understanding of the relationship between the Logos and the logoi, it is argued that this indirectly provides a second Christological way forward to resolve the problem at hand, particularly when the two types of logoi (that ‘of being’ and that ‘of virtue’) are correctly distinguished. Insofar as the Logos and the logoi, not to mention the notions of participation and deification, were viewed by Maximus through his Cyrilline Chalcedonian lens, his Cyrilline Chalcednonian Christology was ultimately his answer to the theological problem of participation.     

Inconsistent Responding in a Criminal Forensic Setting: An Evaluation of the VRIN-r and TRIN-r Scales of the MMPI–2–RF

Criminal forensic evaluations are complicated by the risk that examinees will respond in an unreliable manner. Unreliable responding could occur due to lack of personal investment in the evaluation, severe mental illness, and low cognitive abilities. In this study, 31% of Minnesota Multiphasic Personality Inventory–2 Restructured Form (MMPI–2–RF; Ben-Porath & Tellegen, 2008/2011) profiles were invalid due to random or fixed-responding (T score ≥ 80 on the VRIN–r or TRIN–r scales) in a sample of pretrial criminal defendants evaluated in the context of treatment for competency restoration. Hierarchical regression models showed that symptom exaggeration variables, as measured by inconsistently reported psychiatric symptoms, contributed over and above education and intellectual functioning in their prediction of both random responding and fixed responding. Psychopathology variables, as measured by mood disturbance, better predicted fixed responding after controlling for estimates of cognitive abilities, but did not improve the prediction for random responding. These findings suggest that random responding and fixed responding are not only affected by education and intellectual functioning, but also by intentional exaggeration and aspects of psychopathology. Measures of intellectual functioning and effort and response style should be considered for administration in conjunction with self-report personality measures to rule out rival hypotheses of invalid profiles.     

运动技能水平与躯体感觉输入对运动表象的影响

运动表象质量与运动技能水平有关,运动表象质量随着运动技能水平的提高而上升。器械使用可使人脑产生可塑性改变,使用者会将器械纳入身体图式。然而,两者影响运动表象的神经心理机制还不清楚。本研究采用功能性磁共振成像探析篮球运动员与新手在不同持球条件下表象投篮时脑功能活动的差异。结果表明运动员表象质量较好,镜像神经系统激活高于新手;持球条件下运动员表象质量显著高于不持球条件下,镜像神经系统激活程度显著低于不持球条件下。研究说明持器械可以显著提高运动员的表象质量,器械使用带来镜像神经系统的可塑性变化。     

阅读水平调节儿童阅读眼动注视模式的发展:基于9～11岁儿童的证据

按照3~5年级小学生的语文阅读水平,在各年级中分别选取年龄相同的高、中、低三组儿童作为被试,要求他们阅读适合本年级阅读水平的5篇短文,探讨同一年龄段内读者阅读水平的高低对阅读眼动注视模式的影响是否存在发展上的差异。通过记录其眼动轨迹,结果发现:9岁儿童的阅读眼动注视模式受读者本身阅读水平的影响最大,10岁次之,到11岁,随着儿童基本眼动行为的成熟,这种影响随之消失。表明读者阅读眼动注视模式的发展动力来源于语言操作技能和眼球运动协调性提高的交互作用。     

亲子关系与青少年冒险行为的关系:一个有调节的中介模型

该研究探讨了亲子关系与青少年冒险行为的关系,并提出一个有调节的中介模型,考察自控力的中介效应和不良同伴交往对该效应的调节效应。对1263名青少年采用问卷调查,研究工具包括关系网络问卷、中学生自我控制能力量表、同伴群体特征问卷、青少年冒险行为问卷。结果表明：（1）自控力在亲子关系与青少年冒险行为之间起中介作用,即亲子关系通过自控力间接影响青少年的冒险行为。（2）亲子关系通过自控力的间接效应受到不良同伴交往的调节,交往较多的不良同伴使低自控力青少年的冒险行为增多。因此,自控力在亲子关系与冒险行为之间存在中介效应,且该效应受到不良同伴交往的调节。

Psychometric Properties of the Acceptance and Action Questionnaire – II for Taiwanese College Students and Elite Athletes

The aim of this study was to validate the Taiwanese version of the Acceptance and Action Questionnaire-II (AAQ-II) using a population that consisted of college students and athletes. The authors conducted three independent studies to examine the psychometric properties of the AAQ-II. Study 1 examined the validity of the AAQ-II in a sample of undergraduate students. Study 2 examined the group invariance of the AAQ-II between undergraduate students and athletes. Study 3 examined nomological validity by testing the mediating role of experiential avoidance in the relationship between perceived autonomy support and well?/ill-being indicators. Overall, the results of the confirmatory factor analyses conducted in Study 1 demonstrated the existence of a unidimensional AAQ-II. AAQ-II was positively correlated with depression. The internal consistency of the scale was 0.81. In Study 2, factorial invariance of the AAQ-II was demonstrated across undergraduate students and adolescent athletes. Study 3 showed that perceived autonomy support was related to both depression and negative emotion through experiential avoidance. However, experiential avoidance did not mediate the relationship between perceived autonomy support and positive emotion and life satisfaction. In summary, this study provided preliminary evidence to support the validity and reliability of the AAQ-II and opened a new avenue for cross-cultural researchers.     

感觉寻求、同伴压力对高中生烟酒使用的影响

对来自山东日照市两所普通高中1~3年级的689名学生进行问卷调查,考察感觉寻求、同伴压力（包括烟酒使用同伴压力与其他同伴压力）对高中生烟酒使用的影响,以及同伴压力的调节作用。结果表明：（1）感觉寻求、烟酒使用同伴压力对高中生烟酒使用有正向预测作用,其他同伴压力也能显著预测其饮酒行为。（2）烟酒共用同伴压力调节感觉寻求和高中生烟酒共用间的关系,只有在高烟酒共用同伴压力下感觉寻求才会显著预测烟酒共用;饮酒同伴压力也调节感觉寻求和高中生饮酒间的关系,只有在高饮酒同伴压力下高感觉寻求者才会有较多饮酒行为;其他同伴压力无此调节作用。（3）吸烟同伴压力不能调节感觉寻求和高中生吸烟间的关系。     

干预胆碱M受体对药物成瘾的影响及其与多巴胺的关系

药物成瘾是一类精神及行为障碍, 涉及到中枢神经系统的病变。毒蕈碱受体(Muscarinic receptor, M受体)属于胆碱能受体, 分5种亚型。行为学研究表明, 干预M受体能有效影响药物成瘾行为, 但其神经机制还亟待探索。阿片类药物与精神活性药物均能激活中枢多巴胺系统, 而M受体与多巴胺系统在多个脑区产生了交互作用。其中激动M2及M4受体抑制了多巴胺系统功能, 而激动M5受体增强了多巴胺系统功能, 与干预M2、M4、M5受体对药物成瘾行为的影响相对应。以上证据提示, 干预M受体可能通过影响多巴胺系统对药物成瘾起作用。
