鼓励条件下幼儿提问的发展

以7所幼儿园的141名3～6岁儿童为被试,采用实验方法,探讨幼儿在8种新异刺激条件下提问的发展.结果表明:(1)3～6岁幼儿提问生成的数量随着年龄的增长而提高;(2)幼儿在对当前刺激产生陌生感或出现认知混乱时更容易生成问题;(3)立体刺激材料和平面刺激材料在引发幼儿提问生成上不存在差异;(4)3～6岁幼儿提问元认知随年龄的增长而提高.3～4岁期间是提问原因元认知快速发展时期.     

Deontic Interpreted Systems

We investigate an extension of the formalism of interpreted systems by Halpern and colleagues to model the correct behaviour of agents. The semantical model allows for the representation and reasoning about states of correct and incorrect functioning behaviour of the agents, and of the system as a whole. We axiomatise this semantic class by mapping it into a suitable class of Kripke models. The resulting logic, KD45_n ^i-j, is a stronger version of KD, the system often referred to as Standard Deontic Logic. We extend this formal framework to include the standard epistemic notions defined on interpreted systems, and introduce a new doubly-indexed operator representing the knowledge that an agent would have if it operates under the assumption that a group of agents is functioning correctly. We discuss these issues both theoretically and in terms of applications, and present further directions of work.     

中国与英国儿童对待欺负问题态度的比较研究

采用修订的Olweus欺负问卷,对中国和英国近万名(中国8937名,英国1035名)中小学儿童对待欺负的态度进行调查。结果发现:(1)中国儿童对待欺负的态度比英国儿童积极。(2)儿童对待欺负问题的态度存在性别和年龄差异。女孩比男孩对待欺负的态度较积极;小学儿童对待欺负的态度比初中儿童积极。(3)儿童在欺负/受欺负关系中的角色与其对待欺负问题的态度有联系。未参与者对欺负的态度最积极,其次是受欺负者、欺负/受欺负者,而欺负者对待欺负的态度最消极;(4)儿童对受欺负者的同情多,而去帮助受欺负者的行为倾向少。     

Chaplains' Engagement with Suicidality among Their Service Users: Findings from the VA/DoD Integrated Mental Health Strategy

Chaplains play an important role in supporting the mental health of current and former military personnel; in this study, the engagement of Department of Veterans Affairs (VA), Army, Navy, and Air Force chaplains with suicidality among their service users were examined. An online survey was used to collect data from 440 VA and 1,723 Department of Defense (DoD) chaplains as part of the VA/DoD Integrated Mental Health Strategy. Differences were noted for demographics, work setting characteristics, encountering suicidality, and self‐perceived preparation for dealing with suicidality. Compared to DoD chaplains, VA chaplains encounter more at‐risk service users, yet feel less prepared for dealing with suicidality.     

The impacts of task relevance and cognitive load on adults’ decision information search

ABSTRACT

Higher relevance may increase older adults’ engagement in cognitively demanding activities; however, whether this effect will maintain when available cognitive resources are limited? Consequently, we investigated the joint impact of task relevance and cognitive load on older and younger adults’ decision search behaviors. We adopted a 2 (age: young/old) × 2 (cognitive load: without load/with load) × 2 (task relevance: high/low) mixed design. Sixty-one younger and 63 older adults completed high-relevance and low-relevance decisions. Our results revealed that older (vs. younger) adults took more time and more alternative-based search before decision-making. Both age groups sampled less information with an additional memory task. Additionally, they spent more time and effort to sample more information on high-relevance (vs. low-relevance) decisions; however, such differences disappeared when with an additional memory task. Task relevance promoted both age groups' search engagement, but this effect was subjected to their available cognitive resources.     

Association Between Suicidal Ideation and Exposure to Suicide in Social Relationships Among Family,Friend, and Acquaintance Survivors in South Korea

Exposure to suicide in social relationships may be associated with suicidal ideation among survivors. In South Korea, which is known for having the highest suicide rate among OECD countries, exposure to suicide in social relationships can have serious consequences as social relationships are greatly emphasized in the society. The purpose of this study was to examine the association between survivors' suicidal ideation and their exposure to suicide in close relationships. Data collected through a telephone survey of a total of 1,000 men and women selected from across the nation using a stratified sampling method were analyzed. The results show that individuals who lost a family member, friend, or acquaintance in their lifetime are 4.5 times, 3.7 times, 2.2 times, respectively, more likely to have suicidal ideation in the past year compared to those without such experience. These findings suggest that special intervention for suicide survivors should be considered for those who experience suicide in close relationships.
