大学生问题发现过程的思维特点*

用团体实验考察大学生在生活与科学两个领域中问题发现过程的思维特点。620名大学生参与实验,从问题数量、思维产品、思维层次、思维开放性和思维品质等维度对问题评分。结果显示:(1)不同年级与性别大学生发现问题的整体思维水平相当,男生在思维层次与精致性上占优,态度对问题发现有影响;(2)问题思维评分的领域差异显著;(3)依据问题发现思维的差异可将大学生分为能力强与弱两个类别;(4)大学生发现的大部分问题涉及中等偏下的思维水平。     

6-9岁儿童工作记忆的发展研究

以Baddeley工作记忆模型为基础考察儿童语音环路、视觉空间模板、中央执行的发展及其与复杂广度的关系。225名6-9岁被试完成9个任务,分别测量听力广度及工作记忆三个子系统的功能。发现工作记忆各个子成分的功能在6-9岁期间发展速度不同;中央执行与语音环路和视觉空间模板的联系随年龄增长加强;结构方程模型分析发现中央执行和语音环路功能对儿童听力广度都有显著的直接影响,表明言语复杂广度任务既涉及中央执行功能也涉及语音环路的存贮功能。     

内隐数学-性别刻板印象的SEB研究

本研究采用SEB实验设计,考察大学生的内隐数学-性别刻板印象。结果发现,SEB方法能显著地检测到大学生普遍存在“男性比女性更擅长数学”这样的内隐数学-性别刻板印象;SEB所测量到的内隐数学-性别刻板印象没有性别差异,所测得的内隐数学-性别刻板印象也没有专业差异。     

日常前瞻记忆的年龄差异

在年龄—前瞻记忆悖论现象中,老年人在完成日常前瞻记忆任务时,其表现优于年轻人的现象尤其引人注意。研究者一方面探讨了动机水平、责任心、生活状态以及外部帮助与提示等与主体有关的因素等对这一结果的影响;另一方面也研究了任务本身因素的影响,根据不同任务情境和任务性质的前瞻记忆年龄比较的结果,可以推断日常前瞻记忆年龄差异的来源在于任务的性质而非任务的情境。将来的研究可通过元分析、中介效应检验等手段进一步确定日常前瞻记忆年龄差异的机制。     

运动员与大学生两类人群间内隐攻击性的实验研究

本研究采用IAT测量两类人群(即普通高校大学生与专业运动员)的内隐攻击性并且比较其内隐攻击性在程度上是否存在差异.研究发现个体在攻击性行为倾向上表现出自动化的特征,并且两类人群间内隐攻击性在程度上差异显著,普通大学生和专业运动员的内隐攻击性在性别方面差异不显著.     

中学生心理求助意愿问卷的编制

目的:编制中学生心理求助意愿问卷。方法:经过初测后再选取260名中学生测试该问卷,并进行信度和效度的检验。结果:全量表的克隆巴赫a一致性系数为0.873(n=235,p<0.01);因素分析结果显示为经过初测后确定的四个因子的总方差贡献率为53.644%,四个因子分别为意愿倾向、评价、效果预期、心理卫生知识。结论:中学生心理求助意愿问卷具有较好的信效度,可以作为测查中学生心理求助态度和意愿的工具使用。     

Grandiose and Vulnerable Narcissism,Materialism, Money Attitudes,and Consumption Preferences

Narcissism is increasingly being investigated in the context of consumer attitudes and behavior. Previous research showed that narcissism is reflected in materialistic tendencies and money-related attitudes. However, almost all of these studies concerned the grandiose type of narcissism. We examined relationships of both grandiose and vulnerable narcissism with materialism, money attitudes, and consumption preferences in a nonstudent sample. The results showed that the two types of narcissism are equally associated with materialism and a tendency to conspicuous (public) consumption. Differences between grandiose and vulnerable narcissism with regard to money attitudes were observed. Materialism mediated most of the relationships between narcissism, money attitudes, and consumption preferences, but the patterns of mediation were different for grandiose and vulnerable subtypes. Mutual suppression occurred when grandiose narcissism and materialism predicted anxiety associated with money and when vulnerable narcissism and materialism predicted money perceived as a source of evil. The results suggested that not only grandiose, but also vulnerable narcissists may be prone to excessive consumption and that this can be explained by their materialistic tendencies.     

“When the going gets tough,the tough get going”: Motivation towards closure and effort investment in the performance of cognitive tasks

Previous studies have demonstrated that the need for closure (NFC), which refers to an individual’s aversion toward uncertainty and the desire to quickly reduce it, leads to reluctance to invest effort in judgments and decision making. However, we argue that NFC may lead to either an increase or a decrease in effort depending on the availability of easy vs. difficult means to achieve closure and perceived importance of the task goal. We found that when closure could be achieved via both less and more demanding means, NFC was associated with decreased effort unless the task was perceived as important (Study 1). However, when attaining closure was possible via demanding means only, NFC was associated with increased effort, regardless of the task importance (Study 2). Moreover, NFC was related to choosing a more instrumental strategy for the goal of closure, even if this strategy required effort (Study 3). The results are discussed in the light of cognitive energetics theory.     

类别使用目的对类别典型性效应的影响

采用ERPs技术,对不同类别使用目的的典型性效应进行研究。通过分类方式控制类别使用目的,分别采用包含法和排除法对材料进行类属判断。结果表明:(1)排除组反应时显著短于包含组,表明两种条件下被试可能采取了不同的认知加工策略;(2)在认知加工早期阶段210ms-310ms,包含组引发了更大的N2波幅,这说明类别使用目的对类别典型性表征的影响在早期认知加工阶段就已有所表现。(3)370ms-470ms阶段,典型性样例在排除组引发了比包含组更大的N400;表明类别使用目的影响了典型性表征的加工。
