Physical punishment has received worldwide attention because of its negative impact on children's cognitive and social development and its implications for children's rights. Using UNICEF Multiple Indicator Cluster Surveys 4 and 5 data, we assessed the associations between positive discipline, harsh physical punishment, physical punishment and psychological aggression and preschoolers' literacy skills in 5628 preschool‐aged children and their caregivers in the developing nations of Belize, the Dominican Republic, Guyana, Jamaica and Suriname. Caregivers across countries used high levels of explanations and psychological aggression. There were significant country differences in the use of the four disciplinary practices. In the Dominican Republic and Guyana, physical punishment had negative associations with children's literacy skills, and in the Dominican Republic, positive discipline had a positive association with children's literacy skills. Findings are discussed with respect to the negative consequences of harsh disciplinary practices on preschoolers' early literacy skills in the developing world.  相似文献

In the present study the relative contributions of internal and external sources of variation in children's suggestibility in interrogative situations were examined. One hundred and eleven children (48 4- to 5-year-olds and 63 7- to 8-year-olds) were administered a suggestibility test (BTSS) and the most suggestible (N=36) and the least suggestible (N=36) children were randomly assigned to either an interview condition containing several suggestive techniques or to one containing only suggestive questions. The effects of internal sources of variation in suggestibility were compared with the effects of the interview styles on the children's answers. The former did influence the children, but the external sources of variation in suggestibility had a stronger impact. Influences of cognitive, developmental factors could be found, but not when abuse-related questions were asked and high pressured interview methods were used. These findings indicate that individual assessment of suggestibility can be of some assistance when interviewing children, but diminishing suggestive influences in interrogations must be given priority.  相似文献

Q矩阵标定是实施认知诊断评估的前提,已有Q矩阵修正方法并不太适合测验中已知属性向量的题目数较少的情形。根据拓展Q矩阵理论中可达阵R列与简化Q阵列存在布尔“或”关系,在一定认知假设下,率先提出可达阵R与简化Q阵的潜在反应列存在布尔“与”关系,并由此提出基于可达阵的Q矩阵标定方法。研究显示:在已知一个可达阵下,当可达阵项目的猜测或失误参数在.20以下且待标定项目的项目参数约在.30以下时,新方法所得Q矩阵元素返真率基本在.90以上,并且真实Q矩阵与估计Q矩阵下被试分类准确率差异很小;对于含5个属性的独立结构,新方法要求的随机样本的样本量较小;实证研究也印证了模拟研究的结论。新方法只需专家标定少量题目的Q矩阵,即已经标定的Q矩阵对应属性层级结构的可达阵。  相似文献

Pursuing the line of the difference models in IRT (Thissen &; Steinberg, 1986 Thissen, D., &; Steinberg, L. (1986). A taxonomy of item response models. Psychometrika, 51:567577. doi:10.1007/BF02295596.[Crossref], [Web of Science ®] [Google Scholar]), this article proposed a new cognitive diagnostic model for graded/polytomous data based on the deterministic input, noisy, and gate (Haertel, 1989 Haertel, E. H. (1989). Using restricted latent class models to map the skill structure of achievement items. Journal of Educational Measurement, 26, 333352. doi:10.1111/j.1745-3984.1989.tb00336.x.[Crossref], [Web of Science ®] [Google Scholar]; Junker &; Sijtsma, 2001 Junker, B. W., &; Sijtsma, K. (2001). Cognitive assessment models with few assumptions, and connections with nonparametric item response theory. Applied Psychological Measurement, 25, 258272. doi:10.1177/01466210122032064.[Crossref], [Web of Science ®] [Google Scholar]), which is named the DINA model for graded data (DINA-GD). We investigated the performance of a full Bayesian estimation of the proposed model. In the simulation, the classification accuracy and item recovery for the DINA-GD model were investigated. The results indicated that the proposed model had acceptable examinees' correct attribute classification rate and item parameter recovery. In addition, a real-data example was used to illustrate the application of this new model with the graded data or polytomously scored items.  相似文献

在认知诊断评估实践中,属性层级合理性的验证非常重要,而现有指标仅停留在0-1计分测验,无法适应考试形式和评分方式多样化的实践需求。研究将0-1计分层级一致性指标(MHCI)拓展至多级计分的层级一致性指标(GHCI),模拟和实证研究结果表明:(1)GHCI具有和MHCI相同的本质含义,考虑了父项目和子项目得分的多种可能性,从而将MHCI纳入GHCI体系;(2)在多级或混合计分情境,MHCI会有信息损失,容易发生低估,且易受转换比例的影响;(3)GHCI在模拟和实践情境均具较好的适宜性,拟合截断值的设置可依属性层级而定。  相似文献

Re-reading has been shown to have a minimal benefit on text comprehension, in comparison to reading only once or other types of study techniques (e.g., testing; self-explanation). In two experiments we examined the effect of re-reading on mind wandering. Participants read two texts, during which they responded to intermittent mind wandering probes. One text was read once and the other twice. Consistent with previous findings, there was no effect of re-reading on comprehension even though participants reported feeling more competent when they re-read the text. Critically, participants mind wandered more while re-reading. Furthermore, the effect of re-reading on mind wandering was specific to intentional forms of mind wandering rather than unintentional. The implications of these results for understanding mind wandering and the limited effectiveness of re-reading as a mnemonic are discussed.  相似文献

When causal life-event explanations for disorder symptoms are available, clinicians tend to explain away those symptoms (Ahn, Novick, &; Kim, 2003 Ahn, W., Novick, L. R., &; Kim, N. S. (2003). Understanding behavior makes it normal. Psychonomic Bulletin Review, 10(3), 746752. doi:10.3758/BF03196541[Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Meehl, 1973 Meehl, P. E. (1973). Why I do not attend case conferences. In P. Meehl (Ed.), Psychodiagnosis: Selected papers (pp. 225302). Minneapolis, MN: University of Minnesota Press. [Google Scholar]), eschewing formal diagnostic guidelines such as the DSM-5 (American Psychiatric Association, 2013 American Psychiatric Association [APA]. (2013). Diagnostic and statistical manual of mental disorders (5th ed.). Arlington, VA: American Psychiatric Publishing.[Crossref] [Google Scholar]). We asked whether this effect is attenuated in the context of a structured diagnostic clinical interview procedure, which deliberately directs evaluators' attention to symptoms alone, or whether it is robust enough to continue to emerge. Across two experiments, lay evaluators given causal life-event explanations for disordered behaviors gave them lower judgments of abnormality and need for treatment compared to evaluators not given such explanations, regardless of whether they used a structured clinical interview. Thus, causal life-event explanations may have significant impact on clinical evaluations regardless of the mode of assessment. Implications for the clinical utility of structured interviews and the role of life-event context in diagnosis and classification are discussed.  相似文献

The test-retest reliability of the Spanish Diagnostic Interview Schedule for Children (DISC-IV) is presented. This version was developed in Puerto Rico in consultation with an international bilingual committee, sponsored by NIMH. The sample (N = 146) consisted of children recruited from outpatient mental health clinics and a drug residential treatment facility. Two different pairs of nonclinicians administered the DISC twice to the parent and child respondents. Results indicated fair to moderate agreement for parent reports on most diagnoses. Relatively similar agreement levels were observed for last month and last year time frames. Surprisingly, the inclusion of impairment as a criterion for diagnosis did not substantially change the pattern of results for specific disorders. Parents were more reliable when reporting on diagnoses of younger (4–10) than older children. Children 11–17 years old were reliable informants on disruptive and substance abuse/dependence disorders, but unreliable for anxiety and depressive disorders. Hence, parents were more reliable when reporting about anxiety and depressive disorders whereas children were more reliable than their parents when reporting about disruptive and substance disorders.  相似文献

Chronic Fatigue Syndrome (CFS) is an illness that involves severe, prolonged fatigue as well as neurological, immunological, and endocrinological system pathology. Because the pathogenesis of CFS has yet to be determined, case definitions have relied on clinical observation in classifying signs and symptoms for diagnosis. In an attempt to address various criticisms and inconsistencies in diagnostic criteria, there have been several revisions of the CFS case definition. The current investigation examined the differences between 1988 and 1994 definitions as well as participants who had a psychiatric explanation for their fatigue. Dependent measures included psychiatric comorbidity, symptom frequency, and functional impairment. The 1988 criteria, compared to the 1994 criteria, appeared to select a group of participants with more symptomatology and functional impairment, but these groups did not significantly differ in psychiatric comorbidity. Implications of these findings are discussed.  相似文献
