According to Crain and Nakayama (1987) , when forming complex yes/no questions, children do not make errors such as Is the boy who smoking is crazy? because they have innate knowledge of structure dependence and so will not move the auxiliary from the relative clause. However, simple recurrent networks are also able to avoid such errors, on the basis of surface distributional properties of the input ( Lewis & Elman, 2001 ; Reali & Christiansen, 2005 ). Two new elicited production studies revealed that (a) children occasionally produce structure‐dependence errors and (b) the pattern of children's auxiliary‐doubling errors (Is the boy who is smoking is crazy?) suggests a sensitivity to surface co‐occurrence patterns in the input. This article concludes that current data do not provide any support for the claim that structure dependence is an innate constraint, and that it is possible that children form a structure‐dependent grammar on the basis of exposure to input that exhibits this property. 相似文献

Judgment aggregation problems are language dependent in that they may be framed in different yet equivalent ways. We formalize
this dependence via the notion of translation invariance, adopted from the philosophy of science, and we argue for the normative
desirability of translation invariance. We characterize the class of translation invariant aggregation functions in the canonical
judgment aggregation model, which requires collective judgments to be complete. Since there are reasonable translation invariant
aggregation functions, our result can be viewed as a possibility theorem. At the same time, we show that translation invariance
does have certain normatively undesirable consequences (e.g. failure of anonymity). We present a way of circumventing them
by moving to a more general model of judgment aggregation, one that allows for incomplete collective judgments. 相似文献

考察气质(意志控制、愤怒挫折、感觉寻求)对青少年烟酒使用的主效应,气质与教养方式(权威、专制、纵容)对烟酒使用的交互效应以及气质间的交互效应.采用随机整群抽样的方法,选取660名青少年为被试,匿名完成气质问卷、教养方式问卷和烟酒使用问卷.结果显示:(1)在控制了性别、年龄、社会经济地位后,气质对青少年烟酒使用具有预测作用,低意志控制、高愤怒挫折、高感觉寻求正向预测烟酒使用;(2)教养方式调节部分气质因素与烟酒使用的关系,具体为:权威和专制教养缓冲感觉寻求的风险作用,符合风险缓冲模型;纵容教养增强感觉寻求的风险作用,符合风险增强模型;(3)气质内部在影响青少年烟酒使用时也存在交互作用,愤怒挫折增强感觉寻求的风险作用,符合风险增强模型.因此,烟酒使用是气质与教养方式及气质间交互作用的产物. 相似文献

This study examined exposure to environmental tobacco smoke (ETS), a major public health problem. ETS has been found to be
associated with an increased risk of adverse health effects in children. This study utilizes data from a community-based,
longitudinal investigation examining the relation between children’s exposure to ETS and later internalizing symptoms and
externalizing behaviors. Interviews were administered to a representative community sample of participants from two New York
State counties in 1983, with subsequent interviews in 1985–1986, 1992, 1997, and 2002–2003 (when the participants’ mean age
was 32). Data was collected on various personality and behavioral characteristics of the participants, and on internalizing
symptoms and externalizing behaviors demonstrated by their children. Results indicated that children’s exposure to ETS was
associated with an increased risk for both internalizing symptoms and externalizing behaviors. This relationship was maintained
despite control on a number of parental psychosocial risk factors (e.g., demographic variables, personality and behavioral
attributes) that have been found to be associated with both parental cigarette smoking and behavior problems among children.
These data, which indicate an association between exposure to ETS and internalizing symptoms and externalizing behaviors among
children, support public health policies to further restrict children’s exposure to ETS. 相似文献

Random variables A and B, whose joint distribution depends on factors (x,y), are selectively influenced by x and y, respectively, if A and B can be represented as functions of, respectively, (x,SA,C) and (y,SB,C), where SA,SB,C are stochastically independent and do not depend on (x,y). Selective influence implies selective dependence of marginal distributions on the respective factors: thus no parameter of A may depend on y. But parameters characterizing stochastic interdependence of A and B, such as their mixed moments, are generally functions of both x and y. We derive two simple necessary conditions for selective dependence of (A,B) on (x,y), which can be used to conduct a potential infinity of selectiveness tests. One condition is that, for any factor values x,x′ and y,y′,

An item response theory model for dealing with test speededness is proposed. The model consists of two random processes, a
problem solving process and a random guessing process, with the random guessing gradually taking over from the problem solving
process. The involved change point and change rate are considered random parameters in order to model examinee differences
in both respects. The proposed model is evaluated on simulated data and in a case study.

This case report describes the assessment and treatment of a 69-year-old male medical patient with urethral catheter dependence. Assessment revealed an anxiety/phobic component to the dependence and hypothesized detrusor muscle deconditioning. Retraining of the bladder and desensitization to the anxiety-provoking situation were achieved by exposure to decatheterization in the context of a supportive adult day health care setting. Interdisciplinary collaboration between nursing and psychology were associated with successful functional, social, and psychological outcomes.A psychology intern at the Portland VA Medical Center at the time the study was conducted. 相似文献

Contrasting beliefs and attitudes held by sharecroppers and their landlord on a fazenda in Northeastern Brazil reveal a tendency to split one another into positively and negatively idealized images. Sharecroppers who ambivalently seek patronage construct good vs. bad landlords/patrons. The landlord, defensive about envy and hostility among sharecroppers, constructs good vs. bad tenants/workers. Theory from the Kleinian school of psychoanalysis concerning envy, splitting, and idealization provides a framework for interpreting ethnographic case materials. 相似文献

The experimental evaluation of two components of a community intervention to prevent adolescent tobacco use are described. Youth antitobacco activities (e.g., peer quizzes, sidewalk art, poster and T-shirt giveaways, etc.) and family communications activities (pamphlets to parents and student quizzes of parents) were evaluated in two time-series experiments, each of which was conducted in two experimental and one control community. Students in Grades 6 and 8 and their parents were assessed in a series of four phone surveys in the first experiment and six phone surveys in the second. Implementation of the youth antitobacco and family communications activities led to significantly greater exposure of young people to antitobacco information. They led to increases in parent and youth knowledge about tobacco use and more negative attitudes toward tobacco. In Experiment 2, youths in intervention communities had significantly lower rated intentions to smoke. The findings suggest the value of a modular approach to community interventions for influencing the social context relevant to the onset of adolescent tobacco use. 相似文献
