Students’ Academic Cheating in Chinese Universities: Prevalence, Influencing Factors, and Proposed Action

Quantitative research about academic cheating among Chinese college students is minimal. This paper discusses a large survey conducted in Chinese colleges and universities which examined the prevalence of different kinds of student cheating and explored factors that influence cheating behavior. A structural equation model was used to analyze the data. Results indicate that organizational deterrence and individual performance have a negative impact on cheating while individual perceived pressure, peers’ cheating, and extracurricular activities have a positive impact. Recommendations are proposed to reduce the level of academic cheating in China. Many of these are universal in nature and applicable outside of China as well.     

干扰任务对说谎影响的研究

摘要:本文将干扰任务对记忆的影响同测谎结合起来,试图运用这一方法来对求职者的真实学历和虚假学历进行区分。实验采用模拟面试的方式,对被试在有或无干扰任务条件下进行两次提问,结果发现,四种任务条件对被试真实经历和虚假经历都具有区分度,其中双双条件的区分度是最高的。并且,被试在双双任务条件下虚假经历的得分显著低于其他三种任务条件。     

数字线和离散物体任务训练对儿童整数偏向的影响

通过数字线任务和离散物体任务对81名拥有错误整数偏向的儿童进行干预,再进行分数比较任务,以考查不同干预对错误整数偏向的影响以及分数在心理数字线上的表征方式。结果表明：（1）离散物体组儿童在干预任务中表现较好,在分数比较任务中得分也显著高于数字线组儿童,但反应时要慢于数字线组儿童。（2）正确比较分数时,两组均出现正确整数偏向,但错误的整数偏向依然存在,二者在整数系统扩展到有理数系统这个过渡期同时存在。     

家庭因素中父母情感温暖、文化性与责任心对大学生职业决策自我效能的中介与中介调节研究

目的：探讨大学生家庭因素中父母情感温暖教养方式、文化性家庭环境与责任心对职业决策自我效能的中介效应与中介调节效应。方法：采用责任心量表、职业决策自我效能量表、父母教养方式评价量表和家庭环境量表,对大学四个年级1207名学生进行测量,运用SPSS12.0、AMOS17.0对数据进行统计分析。结果：（1）父母情感温暖通过责任心对大学生职业决策自我效能具有稳定而持久的间接作用。（2）文化性作为父母情感温暖的调节变量,其与父母情感温暖的交互作用对责任心具有明显的预测作用,并通过责任心中介变量,对大学生职业决策自我效能产生稳定而持久的间接作用。     

大学生脑科学素养现状调查

采用《大学生脑科学素养问卷》,对天津市1450名大学生脑科学素养现状进行了调查分析。结果显示:(1)大学生总体脑科学问卷正确率显著低于60%,其中,脑的功能、脑的组织结构和脑与学方面的得分更低;(2)书籍、网络和电视是大学生获取脑科学知识的重要渠道;(3)大学生对脑科学知识的总体关心程度偏低;(4)大学生脑科学素养水平受成长环境和父母文化程度因素的影响,存在年级和性别差异。     

加工时间和加工速度对工作记忆广度的影响

对工作记忆广度机制的四个模型:资源共享模型、任务转换假说、干扰说和时间资源共享模型进行了检验。以60名大学本科生为被试,完成工作记忆广度任务和转换任务。结果表明:加工时间和加工项目数不是影响工作记忆广度的主要因素;工作记忆广度受到加工速度的影响;工作记忆广度和线索-任务转换代价呈显著的负相关关系。结果支持时间资源共享模型,工作记忆广度取决于注意在加工和存储之间快速、灵活的转换。     

视觉和听觉通道下减法与乘法心算加工的ERP特征

研究加工通道的差异以及减法和乘法心算的编码特征,选择100道心算算式,在视觉和听觉两种输入通道下记录并分析了14例正常人的脑事件相关电位(ERP)。结果发现,视觉和听觉通道引发了趋势相反的早中期成分,在额区和中央区产生了显著分离。在慢波阶段,听觉通道下更多激活了颞区,而视觉通道下更多激活了顶-枕区,且慢电位的ERP特征也表现出通道差异。减法和乘法运算以左半球激活为主,但听觉通道下的顶区和颞区出现了显著的右半球优势。减法在视觉通道下优势较大,说明其主要依赖视空间表征;而乘法在听觉通道下更具优势,则主要是由于其以听觉的言语表征方式为主。     

辩证思维与辩证情绪的因果关系探究

辩证情绪是指个体对同一刺激同时体验到积极和消极情绪的一种心理状态.为探索辩证思维和辩证情绪的因果关系,在研究1中首先收集和筛选了诱发辩证情绪的视频;在研究2中,选取219个被试,先通过思维启动改变被试的辩证思维程度,然后考察辩证思维程度的改变对随后诱发辩证情绪强度的影响.结果发现,思维启动(辩证思维和线性思维)引起的辩证思维程度的差异显著,辩证情绪诱发效果显著,辩证思维在启动类型和辩证情绪之间的中介作用显著.这揭示了辩证思维程度的改变确实引起随后诱发的辩证情绪强度的变化,即辩证思维和辩证情绪存在因果关系.     

单侧化准备电位启始时间点的测算:刀切法*

刀切法是统计学家Quenouille提出的一种参数估计方法,由Miller等在1998年首次将刀切法应用在单侧化准备电位(LRP)启始时间点(onset)的测量中。相对于以往单个被试法而言,它是较新的一种统计方法。本文综述了刀切法的统计原理和基本使用过程,并和单个被试法进行了差异比较,最后对这一方法的发展趋势做了展望。     

Mechanisms for attentional modulation by threatening emotions of fear,anger, and disgust

Appropriately attending to threatening environmental stimuli is evolutionarily adaptive and crucial for survival. This study revealed that nonconscious attentional modulation of disgust has different behavioral and event-related potential (ERP) patterns, as compared to fear and anger. To facilitate its evolutionary purpose of avoidance, disgust first diverts rather than attracts attention. Accordingly, the N1 was smaller in a validly than in an invalidly disgust-cued condition. Furthermore, the frontal P3a for disgust, anger, and fear was found to be larger in the valid than in the invalid condition, which was interpreted as an involuntary switching of attention toward threat-related events to mobilize cognitive resources for action or defense. On the contrary, the parietal P3b only occurred at the conscious level; the enhanced P3b indicated that more cognitive resources were being allocated toward the task-relevant but previously less attended location, to ensure the effective achievement of task goals. In addition, group comparisons between individuals with low and high disgust sensitivity showed that the ERP differences between the disgust and the anger/fear conditions at the unconscious level may be attributed only to individuals with high disgust sensitivity. These findings, together with previous knowledge of the effects of fear and anger on attention, strengthen our confidence in the two-stage scheme of attentional modulation by threats, which consists of an early stage of bottom-up response scaling of sensory processing (reflected by the P1 and N1) and a later stage of top-down integration and regulation of emotion and behavior (reflected by the P3).
