Both non-symbolic and symbolic quantity processing are important for arithmetical computation but not for mathematical reasoning

This study investigated whether numerical processing was important for two types of mathematical competence: arithmetical computation and mathematical reasoning. Thousand eight hundred and fifty-seven Chinese primary school children in third through sixth grades took eight computerised tasks: numerical processing (numerosity comparison, digit comparison), arithmetical computation, number series completion, non-verbal matrix reasoning, mental rotation, choice reaction time, and word rhyming. Hierarchical regressions showed that both non-symbolic numerical processing (numerosity comparison) and symbolic numerical processing (digit comparison) were independent predictors of arithmetical computation but neither was a predictor of mathematical reasoning (assessed by number series completion). These findings suggest that the cognitive basis of mathematical performance varies depending on the type of mathematical competence measured.     

Does Positivity Matter? The Impact of Interparental Interactions on Young Adult Conflict Management

The main purpose of our study was to examine the impact of positive inter-parental interactions on the conflict management of young adults. Based on social cognitive theory (SCT), it was hypothesized that exposure to interparental positive interactions would mediate the intergenerational transmission of conflict. The findings only partially supported SCT and provided evidence for intergenerational transmission of conflict. However positivity did not buffer this association. Important contributions of this study include a better theoretical understanding of positivity in relationships and evidence for the intergenerational transmission of positive and negative conflict management tactics. Implications for researchers, clinicians, and educators are presented.

Role of the NO/sGC/PKG signaling pathway of hippocampal CA1 in morphine-induced reward memory

Evidence suggests that the nitric oxide (NO)/soluble guanylyl cyclase (sGC)/cGMP dependent protein kinase (PKG) signaling pathway plays a key role in memory processing, but the actual participation of this signaling cascade in the hippocampal CA1 during morphine-induced reward memory remains unknown. In this study, we investigated the role of the NO/sGC/PKG signaling pathway in the CA1 on morphine-induced reward memory using a conditioned place preference (CPP) paradigm. We found that rats receiving an intraperitoneal (i.p.) injection of 4mg/kg morphine exhibited CPP, whereas rats treated with only 0.2mg/kg morphine failed to produce CPP. Intra-CA1 injection of the neuronal NO synthase (nNOS) inhibitor 7-NI, the sGC inhibitor ODQ or the PKG inhibitor Rp-8-Br-PET-cGMPS had no effect on the acquisition of CPP by 4mg/kg morphine. Intra-CA1 injection of 7-NI blocked the consolidation of CPP induced by 4mg/kg morphine, and this amnesic effect of 7-NI was mimicked by ODQ and Rp-8-Br-PET-cGMPS. Intra-CA1 injection of the NOS substrate L-arg or the sGC activator YC-1 with an ineffective dose of morphine (0.2mg/kg, i.p.) elicited CPP. This response induced by L-arg or YC-1 was reversed by pre-microinjection of Rp-8-Br-PET-cGMPS in the CA1. These results indicated that the activation of the NO/sGC/PKG signaling pathway in the CA1 is necessary for the consolidation of morphine-related reward memory.     

Shear band evolution during large plastic deformation of brittle and ductile metallic glasses

Four monolithic metallic glasses (MMGs) with different plasticities varying from brittle to ductile behavior under unconstrained loading were subjected to small punch testing. All specimens undergo large plastic deformation with multiple cobweb-like shear bands under these conditions. The process of shear band evolution was carefully controlled and investigated. Plasticity of MMGs is characterized by equivalent plastic strain ε* (product of shear band density and critical shear offset). Thus, this article provides an experimental basis for a better understanding of the shear band evolution during plastic deformation of MMGs.     

Parental Control, Adolescent Delinquency, and Young Adult Criminal Behavior

Adolescence and young adulthood are periods of increased autonomy. Higher levels of autonomy could increase the opportunities for risky behavior such as delinquency. During these periods of transition, the role of parental control becomes less clear. Previous studies have demonstrated the association between parental control and adolescent delinquency, but few have extended examination of such association into young adulthood. The purpose of the study is to examine the association between parental control and delinquency and parental control in adolescence and young adult criminal behavior. We propose that, even though adolescents seek autonomy during this stage, lack of parental control is positively associated with delinquency and has continued influence in young adulthood. Using a national longitudinal dataset, we analyzed the relationship between parental control and delinquency. Findings from regression analyses indicated that lack of parental control had a positive association with delinquency both concurrently and longitudinally into young adulthood. When analyzing delinquency in young adulthood, females reported a lower level of delinquency and younger age was associated with more delinquent behavior. Unexpectedly, parents’ college education was positively associated with delinquency in young adulthood. The findings suggest that parental control is still influential through the period of adolescence and early parental control is still influential in young adulthood. Ways to practice parental control and implications of results are further discussed.

从恢复体验到地方依恋:环境偏好与居住时长的作用

探究源自环境的恢复体验(如,放松、平静等)对居住者地方依恋(包括地方依赖和地方认同两个维度)的预测作用,并分析其中的内在过程与情境条件。采用问卷研究法(N=410),结果发现:(1)恢复体验能显著正向预测个体地方依恋;(2)环境偏好在恢复体验与地方依恋之间起完全中介作用;(3)居住时长调节环境偏好与地方依恋(主要是地方认同)之间的关系。研究将有助于探寻环境心理学视角下的压力管理与城市管理协同路径。     

Bootstrap standard error and confidence intervals for the correlations corrected for indirect range restriction

The standard Pearson correlation coefficient, r, is a biased estimator of the population correlation coefficient, ρ(XY) , when predictor X and criterion Y are indirectly range-restricted by a third variable Z (or S). Two correction algorithms, Thorndike's (1949) Case III, and Schmidt, Oh, and Le's (2006) Case IV, have been proposed to correct for the bias. However, to our knowledge, the two algorithms did not provide a procedure to estimate the associated standard error and confidence intervals. This paper suggests using the bootstrap procedure as an alternative. Two Monte Carlo simulations were conducted to systematically evaluate the empirical performance of the proposed bootstrap procedure. The results indicated that the bootstrap standard error and confidence intervals were generally accurate across simulation conditions (e.g., selection ratio, sample size). The proposed bootstrap procedure can provide a useful alternative for the estimation of the standard error and confidence intervals for the correlation corrected for indirect range restriction.     

宗教信仰对亲社会行为的影响

以往研究发现宗教信仰与亲社会行为之间存在显著的正相关, 据此研究者提出“信仰-亲社会假设”试图证实两者的因果关系。本文主要从研究方法、影响因素及心理机制三个方面对信仰影响亲社会行为的研究进展进行介绍和评述。在研究早期, 研究者主要考察宗教信仰的归属身份对个体亲社会行为的影响; 而近年来, 研究者则越来越关注信仰启动对亲社会行为的影响。信仰对亲社会行为的作用受到信仰程度、文化背景、信仰认知和信仰取向等多种因素的影响。未来研究需要有效控制宗教信仰身份对亲社会测量的影响, 明确宗教信仰的操作性定义并改进相关的测量指标, 关注精神性的作用机制、“信仰-亲社会假设”的跨文化效应以及信仰概念对非宗教信仰群体的影响。
