Does Family Cohesion Predict Children's Effort? The Mediating Roles of Sense of Coherence,Hope, and Loneliness

The degree of cohesion and support within families has often been considered a predictor of students' effort-investment and success in school. The objectives of this study are to examine the roles of personal factors (i.e., sense of coherence and hopeful thinking) as well as interpersonal factors (i.e., loneliness) in mediating the relationship between family cohesion and effort. The sample consists of 1719 elementary school children (781 boys and 938 girls) from the fifth and six grades (mean age = 10.25, SD = 0.70) of 29 elementary schools in central Israel. Students answered study questionnaires in the middle of their academic year. Analyses utilizing hierarchical multiple regression and Hayes' bootstrapping approach (PROCESS; Preacher & Hayes, 2008) were used. The results support the distinctive contribution of family cohesion and the mediating roles of sense of coherence and hope (as protective factors) as well as loneliness (as a risk factor) in predicting students' school effort. This study has important educational implications, emphasizing the value of promoting hopeful thinking and coping with loneliness in helping students to thrive in their studies.     

Narrative skill and testimonial accuracy in typically developing children and those with intellectual disabilities

Children must describe maltreatment coherently for their testimony to be influential in court. We know little about how well children with intellectual disabilities (CWID) describe their experiences relative to typically developing (TD) children, despite CWID's vulnerability to maltreatment. We investigated children's reports of an experienced event and compared coherence in CWID (mild to moderate impairment: 7–11 years) with TD children matched for mental (4–10 years) or chronological age (7–11 years). All children included important markers of narrative coherence in their reports. Children with lower mental ages, particularly those with an intellectual disability, included fewer markers of narrative coherence in their reports than children with higher mental ages. Individual markers of narrative coherence, particularly recall of content, predicted accuracy of testimony and resistance to suggestion even when disability and mental age were taken into account. These findings highlight the importance of helping children to describe their experiences coherently.     

Cosmology: What One Needs to Know

Cosmology, the study of the universe, has a past, which is reviewed here. The standard model—the Big Bang, or the hot, dense early universe that is still expanding—is based on observations that are basically consistent but which require additional input to improve the agreement. Out of the early universe came the galaxies and stars that shine today. The future of the universe depends on the density of matter: too much mass leads to the Big Crunch; too little leads to eternal expans ion and cooling. The dark-matter problem prevents us from knowing which will be the fate of the universe. Thelimits of what may be called "scientific" are addressed.     

Exploring the meso-levels of religious mappings: European religion in regional, urban, and local contexts

This is an introductory essay to a special issue on Local and Regional Perspectives on Religion in Western Europe. The introduction seeks to contextualize this special issue in the study of religion in Europe. Based on the articles of the special issue, the article introduces two meso-levels of investigation: regional and local studies, bridging the gap between the national level (the hitherto preferred level of aggregation) and the study of single groups.     

Local Food Environments: They’re All Stocked Differently

The obesity epidemic has widened the aims of prevention research to include the influence of local food environments on health outcomes. This mixed methods study extends existing research focused on local food environments by examining whether community members’ find food accessible. Data from food store audits and one-on-one interviews were analyzed. Results reveal that most of the food stores surrounding the three research sites were convenience stores and non-chain grocery stores; interviewees did not perceive these stores to be “real” food stores. Tobacco and alcohol products were more prevalent in the food stores than all varieties of milk, fresh fruits, or fresh vegetables. Food access varied by site in a manner that was designed to appeal to customers’ race, class, gender, or environment. Findings reveal that local food environments are reflections of social hierarchies. Unraveling the politics of space ought to be a part of broader efforts to promote the public’s health.     

ACACIA: an agent-based program for simulating behavior to reach long-term goals

We present ACACIA, an agent-based program implemented in Java StarLogo 2.0 that simulates a two-dimensional microworld populated by agents, obstacles and goals. Our program simulates how agents can reach long-term goals by following sensorial-motor couplings (SMCs) that control how the agents interact with their environment and other agents through a process of local categorization. Thus, while acting in accordance with this set of SMCs, the agents reach their goals through the emergence of global behaviors. This agent-based simulation program would allow us to understand some psychological processes such as planning behavior from the point of view that the complexity of these processes is the result of agent–environment interaction.     

基于因果关系归类中的实验效应

采用与Rehder实验相同的程序,考察了不同非典型特征值用语和基本比率信息表达方式对基于因果关系归类的影响.实验1结果表明,非典型特征值采用"正常"或典型特征值的相反值并不会对归类中的实验效应产生不同的影响.实验2结果表明,与将基本比率信息表达为具体明确的一个值"75%"相比,"A倾向于具有特征X"的表达方式会削弱一致性效应.突显因果位置效应.这些结果说明.改变两种实验效应强度的是Marsh和Ahn实验中采用的基本比率信息的表达方式而不是Rehder实验中的非典型特征值用语.     

高功能孤独症幼儿空间工作记忆的组块加工缺陷

孤独症谱系障碍者存在空间工作记忆加工缺陷,其具体受损环节尚不明确。组块是一种有效的策略性信息编码方式,是空间工作记忆的关键环节。高度结构化的刺激容易形成高水平组块,因此,刺激结构化程度对记忆效果的影响能够反映个体的组块加工能力。研究采用Sternberg空间工作记忆任务、Corsi空间广度任务,加入刺激结构化因素,考察高功能孤独症幼儿是否存在组块加工缺陷,并探讨组块加工是否直接影响到空间工作记忆容量。实验1采用Sternberg空间工作记忆任务,结果表明,ASD幼儿存在明显的组块加工缺陷。在易于组块的高结构化条件下,健康幼儿的记忆成绩明显较高,而ASD幼儿在高、低结构化条件下的记忆成绩并无显著差异。实验2采用Corsi空间广度任务,结果显示,不论高、低结构化条件,ASD幼儿的空间工作记忆容量均显著低于健康幼儿。但ASD幼儿由于存在组块加工缺陷,在高、低结构化条件下的记忆成绩差异较健康幼儿小。因此,ASD幼儿的组块能力一定程度上影响了空间工作记忆容量。此外,记忆存储器的异常可能也是ASD幼儿空间工作记忆容量不足的重要原因。研究表明,ASD幼儿的空间组块缺陷主要由于弱中央统合的认知风格,他们缺乏自上而下的组块加工动机,难以主动对刺激形成高水平组块编码,从而影响记忆效果。     

The Truth-Conduciveness Problem of Coherentism and a Sellarsian Explanatory Coherence Theory

According to the truth-conduciveness problem of coherentism, the coherence theory of justification can hardly show that coherentist justification is truth-conducive. This problem is generally conceived as the most recalcitrant problem with the coherence theory. The purpose of this paper is to show that it does not pose a serious problem for a certain version of coherentism, namely a Sellarsian explanatory coherence theory of justification combined with the deflationary theory of truth. On this version of coherentism, our epistemic goal is to gradually improve our conceptual framework so as to maximize its explanatory coherence, and there is no substantial norm of truth independent of the norms of justification, so that we cannot evaluate the truth-conduciveness of a belief independently of the norms of justification. I argue that this version of coherentism can cope with the truth-conduciveness problem.     

Local context effects during emotional item directed forgetting in younger and older adults

This paper explored the differential sensitivity young and older adults exhibit to the local context of items entering memory. We examined trial-to-trial performance during an item directed forgetting task for positive, negative, and neutral (or baseline) words each cued as either to-be-remembered (TBR) or to-be-forgotten (TBF). This allowed us to focus on how variations in emotional valence (independent of arousal) and instruction (TBR vs. TBF) of the previous item (trial n-1) impacted memory for the current item (trial n) during encoding. Different from research showing impairing effects of emotional arousal, both age groups showed a memorial boost for stimuli when preceded by items high in positive or negative valence relative to those preceded by neutral items. This advantage was particularly prominent for neutral trial n items that followed emotional items suggesting that, regardless of age, neutral memories may be strengthened by a local context that is high in valence. A trending age difference also emerged with older adults showing greater sensitivity when encoding instructions changed between trial n-1 and n. Results are discussed in light of age-related theories of cognitive and emotional processing, highlighting the need to consider the dynamic, moment-to-moment fluctuations of these systems.
