时间节律的内隐学习及其特征:来自双维度SRT的证据

本文引入双维度SRT方法,以研究时间节律的内隐学习。在第一个实验中,时间节律的内隐学习得到了证明,双维度SRT方法的信度和效果也得到初步验证;实验二则从整体和局部启动角度比较了节律内隐学习和字母序列内隐学习的差异。两个实验得出结论:(1)节律信息可以被内隐地学习到;(2)节律内隐学习和字母序列内隐学习的显露时机不同,前者更加滞后;(3)两者的机制也不同,前者更倾向于以整体方式进行学习。     

How stable is sense of coherence? Changes following an intervention for unemployed individuals

The present investigation was concerned with the changeability of sense of coherence. We examined changes in sense of coherence (SOC) over a six-month period in a sample of Finnish unemployed individuals ( n = 74) participating in an intervention program designed to boost re-employment. Over the study period, participants' sense of coherence improved significantly and re-employed individuals reported the greatest changes. Different changes in the subcomponents of SOC, comprehensibility, manageability and meaningfulness, were found. Contrary to expectations, participants younger than 30 years of age did not show greater changes in their SOC. Initial personal resources were predictors of both positive and negative changes in SOC.     

Means-end coherence,stringency, and subjective reasons

Intentions matter. They have some kind of normative impact on our agency. Something goes wrong when an agent intends some end and fails to carry out the means she believes to be necessary for it, and something goes right when, intending the end, she adopts the means she thinks are required. This has even been claimed to be one of the only uncontroversial truths in ethical theory. But not only is there widespread disagreement about why this is so, there is widespread disagreement about in what sense it is so. In this paper I explore an underdeveloped answer to the question of in what sense it is so, and argue that resolving an apparent difficulty with this view leads to an attractive picture about why it is so.

Self-Controlled Practice to Achieve Neuro-Cognitive Engagement: Underlying Brain Processes to Enhance Cognitive-Motor Learning and Performance

Abstract

While self-controlled practice has been shown to be an effective practice methodology, the neuro-cognitive correlates of its effectiveness are unclear. We investigated whether learners participating in self-controlled practice exhibit increased neuro-cognitive engagement compared to externally controlled practice. Two groups (self-controlled and yoked) of 16 participants practiced and performed a golf putting task over 3 days. Working memory engagement, central executive activity, and cortical activation were assessed via electroencephalography as indicators of neuro-cognitive engagement. The self-controlled group exhibited more consistent working memory engagement, and greater central executive activity, compared to the yoked group during practice. Relationships were also observed between neuro-cognitive engagement during self-controlled practice and performance improvement, indicating that self-controlled practice uniquely benefitted from increased neuro-cognitive engagement.     

The impact of national integration policies on prejudice and psychological well-being: The fundamental role of the clarity and coherence of integration policies

Recent advances in social psychological research have shown that national integration policies influence how immigrants are perceived and treated by the mainstream population. However, the processes by which these policies come to have an impact on prejudice and well-being of the general population are largely unknown. Moreover, past research has often relied on unrepresentative samples limiting generalizability. The present research proposes that when the national integration policies of a given society are perceived as clearly defined and coherent, they have a direct impact on the perceived cultural norm related to those national integration policies. In turn, the perceived cultural norm affects personal attitudes toward cultural norms (i.e., the degree to which individuals support a given policy), which influence the level of anti-immigrant prejudice as well as psychological well-being. Findings from two correlational studies with representative samples of the mainstream population conducted in France on the policy of secularism (N = 940) and in Québec on the policy of interculturalism (N = 912) supported the proposed theoretical model.     

Promoting adolescent sense of coherence: Testing models of risk,protection, and resiliency

Sense of coherence (SOC) is a dispositional trait that has been linked to well‐being in a broad range of populations and contexts. Little is known, however, about the factors associated with SOC development and maintenance across the lifespan. Conceptualized as a condition of resiliency, SOC in adolescents was explored via measures of risk and protection as reported on by 8th and 10th grade students (N = 1619). Employing cumulative indexes of protection and risk, analyses focused on testing four models of resiliency. Further, the relative and cumulative effects of protection and risk were explored across ecological domains. Analyses revealed support for the compensatory model of resiliency for males and females, while the challenge model also was supported for females. Analyses also revealed that protection and risk influencing SOC emerge at multiple domains for males and females. In addition, protective factors present at multiple domains were related to higher SOC while risk factors present at multiple domains were related to lower SOC regardless of gender. Results suggest a resiliency framework that considers multiple ecological domains is useful for understanding SOC in adolescents. Implications for additional research are presented.

Evaluating Explanations in Law, Science, and Everyday Life

ABSTRACT— This article reviews a theory of explanatory coherence that provides a psychologically plausible account of how people evaluate competing explanations. The theory is implemented in a computational model that uses simple artificial neural networks to simulate many important cases of scientific and legal reasoning. Current research directions include extensions to emotional thinking and implementation in more biologically realistic neural networks.     

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.
