坚毅力的代际传递:父母教养方式的中介作用

从代际传递的角度,考察父母坚毅力和子女坚毅力的关系,同时检验教养方式在二者之间的中介作用。方法：采用问卷法对北京市三所中学初一、初二年级共302名青少年及其父母的数据进行调查,研究工具采用坚毅力问卷（Grit-Scales）、父母教养方式问卷（PBI）。结果：（1）父亲和母亲的坚毅力总分及两个维度兴趣一致性、坚持努力均可正向预测青少年坚毅力总分及各维度;（2）父亲教养方式的关爱维度在父亲坚毅力与孩子坚毅力之间起中介作用,母亲教养方式的关爱维度在母亲坚毅力与孩子坚毅力之间起中介作用。结论：坚毅力存在代际之间的传递,并且教养方式的关爱维度在代际传递过程中起部分中介作用。     

基于视听双通道的音乐情绪冲突效应及优势通道研究

为探讨基于视听双通道的音乐情绪冲突效应、冲突情境下的优势加工通道和音乐经验对结果的影响,本研究采用音乐表演视频为材料,比较音乐组和非音乐组被试在一致型和不一致型视听双通道下的情绪评定速度、准确性及强度。结果发现:(1)一致型条件下的情绪评定更准确且更强烈;(2)不一致型条件下,被试更多以听觉通道的情绪线索为依据进行情绪类型评定;(3)非音乐组被试比音乐组被试更依赖视觉通道的情绪线索。结果表明:通道间情绪信息的不一致阻碍了音乐情绪加工; 听觉通道是音乐情绪冲突情境下的优势加工通道; 音乐经验降低了情绪冲突效应对音乐组被试的干扰。     

“有声有色”的触觉体验：来自多感觉通道整合的线索

虚拟现实技术通过提供视觉、听觉和触觉等信息为用户创造身临其境的感知体验, 其中触觉反馈面临诸多技术瓶颈使得虚拟现实中的自然交互受限。基于多感官错觉的伪触觉技术可以借助其他通道的信息强化和丰富触觉感受, 是目前虚拟现实环境中优化触觉体验的有效途径。本文聚焦于触觉中最重要的维度之一——粗糙度, 试图为解决虚拟现实中触觉反馈的受限问题提供新思路。探讨了粗糙度感知中, 视、听、触多感觉通道整合的关系, 分析了视觉线索(表面纹理密度、表面光影、控制显示比)和听觉线索(音调/频率、响度)如何影响触觉粗糙度感知, 总结了当下调控这些因素来改变粗糙度感知的方法。最后, 探讨了使用伪触觉反馈技术时, 虚拟现实环境中视、听、触觉信息在呈现效果、感知整合等方面与真实世界相比可能存在的差异, 提出可借鉴的改善触觉体验的适用方法和未来待研究的方向。     

正念训练对康复期精神分裂症患者抑制控制的影响

探究正念训练对康复期精神分裂症患者正念觉知水平和抑制控制能力的影响。选取54名康复期精神分裂症住院患者随机分为正念组和对照组。对照组予以常规康复治疗,正念组在常规康复治疗基础上进行8周正念训练。结果发现：（1）在正念觉知方面,正念组后测得分显著高于前测,对照组前后测得分无显著差异;正念组后测得分显著高于对照组。（2）在抑制控制方面,正念组后测Stroop任务反应时显著低于前测,对照组前后测反应时无显著差异;正念组后测反应时显著低于对照组。结果表明,正念训练有助于提高康复期精神分裂症患者正念觉知水平和改善其抑制控制能力。     

Therapy with Families in China: Cultural Factors Influencing the Therapeutic Alliance and Therapy Goals

Rapid economic and social development in China is producing opportunities for a better standard of living for many families but also is associated with significant stress. Family therapy is one of the forms of mental health services that have become increasingly available. Western-derived models of family therapy are being used and adapted to meet the cultural traditions and needs of Chinese families. This article describes a variety of Chinese cultural factors that can influence the establishment of therapeutic alliances with family members (communication styles, collectivist values, family roles, and structure) and those that can shape family therapy interventions by addressing contextual factors affecting Chinese families (economic development, migration patterns, academic pressure, and changing gender roles for women). Suggestions are offered for using cultural sensitivity to address these factors tactfully to build strong therapeutic alliances and help families cope with significant life stresses.     

Local intracortical circuitry not only for feature binding but also for rapid neuronal responses

Neurons of primary sensory cortices are known to have specific responsiveness to elemental features. To express more complex sensory attributes that are embedded in objects or events, the brain must integrate them. This is referred to as feature binding and is reflected in correlated neuronal activity. We investigated how local intracortical circuitry modulates ongoing-spontaneous neuronal activity, which would have a great impact on the processing of subsequent combinatorial input, namely, on the correlating (binding) of relevant features. We simulated a functional, minimal neural network model of primary visual cortex, in which lateral excitatory connections were made in a diffusive manner between cell assemblies that function as orientation columns. A pair of bars oriented at specific angles, expressing a visual corner, was applied to the network. The local intracortical circuitry contributed not only to inducing correlated neuronal activation and thus to binding the paired features but also to making membrane potentials oscillate at firing-subthreshold during an ongoing-spontaneous time period. This led to accelerating the reaction speed of principal cells to the input. If the lateral excitatory connections were selectively (instead of “diffusively”) made, hyperpolarization in ongoing membrane potential occurred and thus the reaction speed was decelerated. We suggest that the local intracortical circuitry with diffusive connections between cell assemblies might endow the network with an ongoing subthreshold neuronal state, by which it can send the information about combinations of elemental features rapidly to higher cortical stages for their full and precise analyses.     

内隐联系测验的修正——简式内隐联系测验

简式内隐联系测验(Brief Implicit Association Test,BIAT),是对内隐联系测验(Implicit Association Test,IAT)(也称为内隐联想测验)的修正,它由两部分联合任务组成,使用传统IAT中的两类别的属性材料和两类别的概念材料以及与IAT相同的联接-反应对。在设计BIAT时,焦点类别的选定对其测量效果有着至关重要的影响,Sriram和Greenwald的研究已经初步证明BIAT方法可以成功运用于测量内隐态度,认同和刻板印象。本文回顾了内隐联系测验发展过程中的各种变式,着重介绍了简式内隐联系测验,结合Sriram的应用对其进行综合评价并建议在今后的研究中对此方法进行验证。     

Reconceptualizing Excitation Transfer as Motivational Activation Changes and a Test of the Television Program Context Effects

This study theorizes that activation and decay of dual motivational systems function as the mechanisms underlying excitation transfer theory. Following this reconceptualization, a physiological experiment simultaneously examines the influence of program valence and arousing content on subsequent ads. As predicted, sympathetic arousal (indicated by skin conductance) was greater during ads following arousing compared to calm programs, and in both conditions, it decreased across ad blocks. Cognitive effort was higher (indicated by slower heart rate) during ads following the positive arousing program and was lower (indicated by faster heart rate) following the negative arousing program. The recognition and free recall data generally support the prediction that, immediately following the program, they would be at the levels predicted by the motivational activation elicited by the program context.     

Grain growth as a stochastic and curvature-driven process

Grain growth subjected to the interplay of stochastic and curvature-driven mechanisms in a single-phase system has been investigated. Numerical results have shown that when the grains are smaller than several tens of nanometres the dominating mechanism is stochastic diffusion control of boundaries. As the grains grow the influence of the deterministic curvature-driven mechanism increases and finally controls the process. In terms of finite-difference solutions to the Fokker–Planck continuity equation, the predicted grain size approaches a log-normal distribution, which agrees well with experimental observations.
