问题解决测验中过程数据的特征抽取与能力评估

基于计算机的问题解决测验可以实时记录被试探索环境和解决问题时的详细行动痕迹,并保存为过程数据。首先介绍了过程数据的分析流程,然后从问题解决测验入手,分别对过程数据的特征抽取和能力估计建模两方面的研究进行了梳理和评价。未来研究应注意：提高分析结果的可解释性;特征提取时纳入更多信息;实现更复杂问题情景下的能力评估;注重方法的实用性;以及融合与借鉴不同领域的分析方法。     

铁钦纳的存在主义

铁钦纳(E.B.Titchener 1867—1927)自称他的心理学为存在主义的。铁钦纳把他的心理学与当时美国的机能主义心理学相对立。西方心理学界一般称铁钦纳的心理学为构造主义。 铁钦纳认为心理学的问题,如其他自然科学一样,是:什么?怎样?和为什么?三个问题。心理学的什么,是将心理现象分析为它的元素;心理学的怎样,是寻求这些元素如何互相联系的规律;心理学的为什么,是以一个心理过程相应的神经过程来解释这     

The role of dark pattern stimuli and personality in online impulse shopping: An application of S-O-R theory

Online impulse shopping is a growing industry. This paper uses the Stimulus-Organism-Response framework to model online impulse purchase behavior using a novel combination of stimuli and organism characteristics. The stimuli: social proof, limited-quantity scarcity, and high-demand, are three commonly used website features known as dark patterns. The organism characteristic personality is measured by the big 5 personality traits and persona generated through latent profile analysis. Using the machine learning algorithm XGBoost, impulse purchasing response was predicted separately for each dark pattern stimuli. Results show personality characteristics are important features when predicting consumer impulse purchasing in response to dark pattern messages. Moreover, the personality traits (and personas) most predictive of impulse shopping behavior varied by type of dark pattern. Findings suggest personality influences susceptibility to different dark patterns, indicating a need for tailored interventions to mitigate individual consumer vulnerabilities to impulse shopping.     

The precision of velocity discrimination across spatial frequency

The precision of velocity coding for moving stimuli of different spatial frequencies was assessed by measuring velocity discrimination thresholds for a 1-c/deg grating paired with a grating whose spatial frequency ranged from 0.25 to 4 c/deg and for grating pairs of the same spatial frequency (0.25, 1, and 4 c/deg). The gratings always moved upward, with velocities ranging from 0.5 to 16 deg/sec, Velocity discrimination was as precise for stimuli that varied in spatial frequency by: ±2 octaves (0.25 vs. 1 c/deg and 4 vs. 1 c/deg) as for stimuli of the same spatial frequency, for specific ranges of velocity that depended on the spatial and, therefore, the temporal frequencies of the stimuli. Compared with a 1-c/deg grating, the perceived velocity of 4-c/deg gratings was about 1.3 times faster and that of 0.25-c/deg gratings was about 1.3 times slower. Although these perceived velocity biases imply variation of velocity-signal processing among spatial frequency channels, the discrimination results indicate that the motion-sensing system can compare signals across different spatial frequency channels to make fine velocity discrimination within appropriate temporal frequency limits.     

An intensional epistemic logic

One of the fundamental properties inclassical equational reasoning isLeibniz's principle of substitution. Unfortunately, this propertydoes not hold instandard epistemic logic. Furthermore,Herbrand's lifting theorem which isessential to thecompleteness ofresolution andParamodulation in theclassical first order logic (FOL), turns out to be invalid in standard epistemic logic. In particular, unlike classical logic, there is no skolemization normal form for standard epistemic logic. To solve these problems, we introduce anintensional epistemic logic, based on avariation of Kripke's possible-worlds semantics that need not have a constant domain. We show how a weaker notion of substitution through indexed terms can retain the Herbrand theorem. We prove how the logic can yield a satisfibility preserving skolemization form. In particular, we present an intensional principle for unifing indexed terms. Finally, we describe asound andcomplete inference system for a Horn subset of the logic withequality, based onepistemic SLD-resolution.     

儿童镜像书写的研究

本实验选择了幼儿园大班,小学一、三、五年级的5—12岁右利儿童133人,用八种书写方式书写自己的姓名、阿拉伯数字1—10和八个汉字,同时检查了儿童的定向能力。结果表明:随着年龄的增大,镜像书写出现的人次和数目减少;自左往右的习惯方向书写所出现的镜像人次和数目比自右往左的非习惯方向少;左手出现镜像书写比右手多;双手同时书写比单手出现的镜像书写多;有空间定向力的比仅有自身定向和无定向力的人出现的镜像书写少。本文验证了镜像书写形成的传统假说后,进一步提出了熟练理论:随着对汉字和数字的认知与视-书写运动图式的牢固掌握,镜像字体的出现就逐渐减少,并认为镜像书写存在着一个复杂的机制,是受多因素控制的。     

反思自我评价的性质

反思自我评价是指个体对于他人如何看待自己的知觉;它对自我概念、种族认同的形成起着重要作用。反思自我评价并不完全准确,它受熟悉性,自尊水平等多种因素的影响。关于反思自我评价的形成,目前主要有三种理论：直接观察模型、他人反馈模型和自我理论模型。由于中西方在文化、社会和历史背景上的不同,应加强建构适合我国文化背景的反思自我评价理论;另外,也应加强对反思自我评价研究的应用探讨。     

熟练汉-英双语者的语码切换机制—— 来自短语水平的证据

以熟练汉-英双语者为被试, 考察了在短语水平上语码切换的机制及切换代价的来源。结果表明：(1)汉语与英语表示空间方所的短语的差异和表示量的短语的对应与否影响语码切换过程, 但对于两种语言的切换代价的影响不显著, 表明语码切换代价未受特定语言的语法特征影响; (2)熟练汉-英双语者在短语水平上表现出语码切换代价的不对称性：切换至熟练语言的代价比切换至非熟练语言的代价大; (3)熟练汉-英双语者的切换代价源于两种语言短语的激活和竞争, 支持非特定语言选择假说, 可以用抑制控制模型来解释。整个研究表明, 熟练双语者的语码切换代价源于语言表征系统之外。     

越富有越不支持再分配?——社会阶层与再分配偏向的关系及其心理机制

社会阶层是影响再分配偏向的重要因素。研究发现, 与低阶层者相比, 高阶层者再分配偏向更低。基于以往研究, 提出高社会阶层者低再分配偏向的作用机制及干预模型。依据该模型, 动机方面的经济自利与系统合理信念, 认知方面的经济不平等感知、贫富差距归因与刻板印象, 情感方面的同情心与地位焦虑是影响高阶层者再分配偏向的中介因素; 培育谦卑心态、进行反刻板印象干预、利用不平等框架效应、提高同情心、改变阶层文化价值观有助于提升高阶层者的再分配偏向。未来研究可对高阶层者的慈善行为及部分低阶层者拒绝再分配的现象加以关注, 深入考察和完善该模型的作用机制, 探索提升高阶层者再分配偏向的策略。
