概念性内隐记忆和外显记忆中熟悉性的关系研究

该文运用任务分离法和Remember/Know程序,以汉词为材料,研究集中注意和重度分散注意条件下概念性内隐记忆和熟悉性提取的关系。结果表明:(1)概念性内隐记忆和线索回忆中的熟悉性在两种注意水平下差异均显著,它们随注意负荷的增加而提高;(2)类别范例测验中不存在错误记忆,而线索回忆中出现了错误记得和错误知道。     

飞行员动态空间表征建构的策略研究

运用动态视觉空间工作记忆任务探讨了飞行员和对照组的动态空间表征的建构特征。从两个方面考察策略运用:(1)在客体运动轨迹表征反应选择项上,根据客体运动轨迹的几何特征将选择项设置为整体型策略和局部型策略;(2)有关策略运用的问卷测试。结果发现,在完成运动轨迹的动态工作记忆时,飞行员更多采用整体策略,控制组更多采用局部。结果提示具有较高空间能力的飞行员在合并运动刺激元素、整合客体表征转化为整体表征时具有优势。最后提出延时动态空间表征表达运动客体运动轨迹表征,其空间构型依赖于一段时间的客体运动特性的积累。     

航线飞行技术性技能与航线飞行阶段任务的关系研究

通过文献、专家意见和问卷调查,构建了现代航线飞行技术性技能多维评价量表。对118名航线飞行员测评数据的验证性因素分析表明,由倾斜控制、偏航控制、平衡控制和速度控制构成的4维模型在飞行准备/滑行、起飞/爬升、巡航、下降/进近/着陆四个飞行阶段均有较好的信度和效度;多元回归分析发现,各维度对不同航线飞行阶段任务均有显著影响。航线飞行技术性技能评价量表的构建为现代航线飞行员选拔与训练、机组驾驶行为规范性评价以及飞行安全管理考核模式的设计奠定了一个良好的工作基础。     

我国中学语文和历史教学目标分类取向的研究

本研究采用文献研究法,查阅了2000年以来中学语文和历史教案共303篇,对教案中教学目标的相关信息作点计数据处理,并进行卡方检验,结果表明:⒈近几年来我国中学语文和历史教学绝大多数采用布卢姆的教育目标分类取向;⒉两者的教学目标侧重于认知领域;⒊两者在认知和情感领域的目标要求学生达到的水平偏低,在动作技能领域的目标要求学生达到的水平偏高;⒋中学历史教学目标中对动作技能领域的理解有偏差;⒌两者在认知和情感领域的教学目标陈述时用词单一或含糊,而动作技能领域教学目标的陈述较清晰。研究结果提示,提高广大一线教师有关教学目标的分类理论及科学地运用教学目标的陈述技术仍有很长的路要走。     

Representing Sudden Shifts in Intensive Dyadic Interaction Data Using Differential Equation Models with Regime Switching

A growing number of social scientists have turned to differential equations as a tool for capturing the dynamic interdependence among a system of variables. Current tools for fitting differential equation models do not provide a straightforward mechanism for diagnosing evidence for qualitative shifts in dynamics, nor do they provide ways of identifying the timing and possible determinants of such shifts. In this paper, we discuss regime-switching differential equation models, a novel modeling framework for representing abrupt changes in a system of differential equation models. Estimation was performed by combining the Kim filter (Kim and Nelson State-space models with regime switching: classical and Gibbs-sampling approaches with applications, MIT Press, Cambridge, 1999) and a numerical differential equation solver that can handle both ordinary and stochastic differential equations. The proposed approach was motivated by the need to represent discrete shifts in the movement dynamics of \(n= 29\) mother–infant dyads during the Strange Situation Procedure (SSP), a behavioral assessment where the infant is separated from and reunited with the mother twice. We illustrate the utility of a novel regime-switching differential equation model in representing children’s tendency to exhibit shifts between the goal of staying close to their mothers and intermittent interest in moving away from their mothers to explore the room during the SSP. Results from empirical model fitting were supplemented with a Monte Carlo simulation study to evaluate the use of information criterion measures to diagnose sudden shifts in dynamics.     

自我效能感影响航线飞行安全绩效的多重中介模型

采用问卷法调查了138名民航飞行员,探讨了自我效能感对飞行安全绩效的影响,以及在这一影响过程中组织信任、组织承诺和工作投入的作用。结果显示,自我效能感对组织信任、组织承诺、工作投入和安全绩效有直接正向作用。组织信任在自我效能感对组织承诺、工作投入、安全绩效的影响中有部分中介作用。组织承诺与工作投入在自我效能感对安全绩效影响中发挥着部分中介作用。结论:自我效能感对安全绩效有直接效应,并可通过组织信任、组织承诺和工作投入对安全绩效产生间接影响。     

TISK 1.0: An easy-to-use Python implementation of the time-invariant string kernel model of spoken word recognition

This article describes a new Python distribution of TISK, the time-invariant string kernel model of spoken word recognition (Hannagan et al. in Frontiers in Psychology, 4, 563, 2013). TISK is an interactive-activation model similar to the TRACE model (McClelland & Elman in Cognitive Psychology, 18, 1–86, 1986), but TISK replaces most of TRACE’s reduplicated, time-specific nodes with theoretically motivated time-invariant, open-diphone nodes. We discuss the utility of computational models as theory development tools, the relative merits of TISK as compared to other models, and the ways in which researchers might use this implementation to guide their own research and theory development. We describe a TISK model that includes features that facilitate in-line graphing of simulation results, integration with standard Python data formats, and graph and data export. The distribution can be downloaded from https://github.com/maglab-uconn/TISK1.0.     

Space-time compatibility effects in the auditory modality

Previous research suggests that past and future temporal concepts are spatially represented from left to right along a mental line. And these concepts can both prime motor responses to left or right space and direct visual spatial attention. The present study aimed at investigating the nature of this space-time conceptual metaphor in different auditory tasks. In the first experiment, subjects categorized time-related words (past or future) that were presented binaurally. In the second experiment, subjects detected left-ear or right-ear targets following time-related words. The similar space-time compatibility effects were found in these two experiments. Our results demonstrate that the activation of temporal concepts can both prime motor responses to left or right space and influence the orientation of auditory spatial attention, suggesting that the modality of the stimulus input is unimportant for the left-right mapping of time. These results are explained by the "intermediate coding" account.     

视觉表象产生加工的可塑性水平研究

采用标准化的视觉表象产生任务,以经过系统训练以及三个不同年龄阶段被试为研究对象来研究视觉表象产生加工时所表现出的可塑性水平。研究结果表明,视觉表象产生加工水平会因外界系统训练而发生功能增强的练习效应,也表现出随着个体的发展所呈现出的年龄效应,年幼儿童还不能产生空间表征,9岁左右可能是儿童类别表象产生能力发展的一个重要时期,也是个体视觉表象产生加工能力可塑性最高的时期。说明由于受大脑神经细胞活动特性改变的影响,视觉表象产生能力具有相对较高的可塑性和易变性特点。
