基于HO-DINA模型的多级评分认知诊断模型的开发

本文对具有较好发展前景的HO-DINA模型进行拓展,将仅适用于0-1评分题型的HO-DINA模型拓广至可用于多级评分题型,采用MCMC算法实现了对模型参数的估计,并对新模型性能进行了研究。研究发现: （1）本文拓展的多级评分HO-DINA模型参数估计精度较高且诊断正确率较高。（2）多级评分的HO-DINA模型诊断的属性个数越多,属性参数（ 和 ）和s参数估计的精度越差、属性诊断的正确率（MMR和PRM）越低,但能力参数（ ）和g参数的估计精度反而越高。（3）在当前条件下,若想保证属性模式判准率在80%以上,建议诊断的属性个数不宜超过7个。     

视觉空间关系判断的分离与协同

采用任务表征相互影响范式,通过三个实验探讨了类别空间关系判断和数量空间关系判断的加工特性和相互关系.结果表明:(1)先行类别关系启动有利于数量空间关系判断,对类别空间关系判断没有影响;先行数量关系启动对两个判断任务均无影响.(2)先行类别关系干扰降低两个空间关系判断的绩效,先行数量关系干扰对两个空间关系判断没有影响.(3)先行类别关系对空间关系判断的启动和干扰效应不局限于特定条件,具有普遍性.研究提示,右脑为优势半球的数量关系加工以左脑为优势半球的类别关系加工为基础,支持视觉空间认知加工既分离又协同的观点.     

Supervisors’ Ethical Leadership and Employee Job Satisfaction: A Social Cognitive Perspective

Although several studies explored the relationship between supervisors’ ethical leadership and employee job satisfaction, little information is available on this relationship in the Chinese context. We propose that moral cognition is an essential process in the relationship between supervisor’s ethical leadership and employee subjective well-being. The present study, through the lens of the social cognitive theory, examined the relationship between supervisors’ ethical leadership and employee job satisfaction, as well as the employee moral-cognitive processes between them. Based on 371 employees in a Chinese enterprise, the present study employed structural equation modeling to examine the hypothesized research model. The results confirmed that supervisors’ ethical leadership was positively related to employee moral awareness, moral identity and job satisfaction, respectively. Moreover, employee moral awareness and moral identity partially mediated the relationship between supervisors’ ethical leadership and employee job satisfaction. The theoretical and managerial implications were further discussed.     

Therapists as fixed versus random effects-some statistical and conceptual issues: a comment on Siemer and Joormann (2003)

The authors disagree with M. Siemer and J. Joormann's assertion that therapist should be a fixed effect in psychotherapy treatment outcome studies. If treatment is properly standardized, therapist effects can be examined in preliminary tests and the therapist term deleted from analyses if such differences approach zero. If therapist effects are anticipated and either cannot be minimized through standardization or are specifically of interest because of the nature of the research question, the study has to be planned with adequate statistical power for including therapist as a random term. Simulation studies conducted by Siemer and Joormann confounded bias due to small sample size and inconsistent estimates.     

Measuring stress responses in postpartum mothers: perspectives from studies in human and animal populations

Reduced hypothalamic-pituitary-adrenal (HPA) responses to stress during the last week of pregnancy and lactation have been consistently observed in rat studies. Several contributing factors have been proposed for this phenomenon in lactation, including the suckling stimulus from the pups, hormones (oxytocin and prolactin) and opioids, a decrease in the ability of noradrenaline to potentiate hypothalamic responses and changes in pituitary responsiveness to ACTH secretagogues (AVP and CRF). In contrast to this vast literature using the rat model, only few studies have addressed this issue in the human population. The consensus is that women engaging in breastfeeding activities exhibit reduced anxiety, although the reductions in neuroendocrine and autonomic responses to stressors are variable, in part because of the different nature of the stressors used. Further work is required to investigate how additional factors, such as maternal parity or emotional salience of the stressor can affect stress responsiveness in postpartum women. Here, we review first the findings regarding stress responsiveness during lactation in both rat and human studies, and then discuss potential research avenues and methodological issues that could be the lead to future research protocols in human subjects. Knowing the reciprocal relationship in the mother-infant dyad, it is clear that investigation of the mechanisms regulating stress responses and mental health in postpartum mothers can only be beneficial to the development of the infant.

Development and current status of counselling psychology in Taiwan

This article details the three stages of counselling psychology’s development in Taiwan, including pre-legislation, legislation and post-legislation. In pre-legislation stage, a brief historical review of the growth of counselling and guidance is introduced, which is the root of the contemporary counselling psychology. The process of the Psychology Act’s legislation is described in legislation stage and the relationships between counselling teachers and clinical psychologist are also discussed. In the post-legislation stage, the licensure system, training programmes, main professional organizations, work settings, and the major opportunities and challenges for the counselling psychology field are presented. In addition, the article refers to data from a national survey of 124 counselling psychologists to provide a profile of the counselling psychologists in Taiwan.     

Intervention to Strengthen Emotional Self-Regulation in Children with Emerging Mental Health Problems: Proximal Impact on School Behavior

A model for teaching children skills to strengthen emotional self-regulation is introduced, informed by the developmental concept of scaffolding. Adult modeling/instruction, role-play and in vivo coaching are tailored to children’s level of understanding and skill to promote use of skills in reallife contexts. Two-hundred twenty-six kindergarten—3rd grade children identified with elevated behavioral and social classroom problems from a population-based screening participated in a waitlisted randomized trial of the Rochester Resilience Project derived from this model. In 14 lessons with school-based mentors, children were taught a hierarchical set of skills: monitoring of emotions; selfcontrol/ reducing escalation of emotions; and maintaining control and regaining equilibrium. Mentors provided classroom reinforcement of skill use. Multi-level modeling accounting for the nesting of children in schools and classrooms showed the following effects at post-intervention: reduced problems rated by teachers in behavior control, peer social skills, shy-withdrawn and off-task behaviors (ES 0.31–0.47). Peer social skills improved for girls but not for boys. Children receiving the intervention had a 46% mean decrease in disciplinary referrals and a 43% decrease in suspensions during the 4-month intervention period. Limitations and future directions to promote skill transfer are discussed.     

Investigation of fine motor performance in children younger than 36-month-old using PDMS-2 and Bayley-III

ABSTRACT

The aim of the study was to investigate the concurrent validity of fine motor (FM) development scores between the Peabody Developmental Motor Scales, Second Edition (PDMS-2), and Bayley Scale of Infant and Toddler Development, Third Edition (Bayley-III). Both tests were administered to 223 children aged 13–36 months with suspected developmental delays from a medical centre. Concurrent validity and agreement of FM delay were assessed. The Bayley-III FM scale scores (FMSS) and motor composite quotients were moderately correlated with PDMS-2 FM quotients. The agreement of FM delay between the two instruments was excellent (Kappa coefficient value = .80) in children aged 13–18 months and good in children aged 19–36 months. When using PDMS-2 as the reference standard, Bayley-III (FMSS < 7) identified fewer children aged 19–24 months as delayed but more in children aged 25–36 months as delayed. When adjusting the cut-off point of Bayley-III FMSS to 8 for children aged 19–24 months and to 6 for children aged 25–36 months, the agreement improved between these two instruments. FM delays might be underestimated solely using Bayley-III in children aged 19–24 months. Additional tests, such as PDMS-2 should be considered to avoid delays in accessing early intervention services.
