子图问题学习对几何解题迁移的影响

将一个图形（称为母图）的若干条线段删除后得到的图形叫做母图的子图。运用实验方法探讨了子图结构学习和子图变式学习对解决问题的迁移效果。结果表明：子图结构学习仅对解决“图形结构相同、逻辑结构相同”问题有明显迁移作用;子图变式学习对解决“图形结构相同、逻辑结构相同”没有明显迁移作用,对“图形结构相似、逻辑结构相同”、“图形结构相同、逻辑结构相似”以及“图形结构相似、逻辑结构相似”四类问题均有明显迁移作用。     

Insight into illness and adherence to psychotropic medications are separately associated with violence severity in a forensic sample

Violence towards others by a minority of psychotic individuals is a significant public health concern. The severity of this other-directed violence (ODV) in the community may be influenced by insight into illness and adherence to psychotropic medications; however, few studies have tested these associations. Sixty male psychotic inpatients, legally detained at a forensic unit in New York City, were assessed with semi-structured interviews, supplemented with information from hospital and official records, family members and the treating clinician. Results indicated that in this unique sample of detained persons with psychotic disorders; (1) increase in the severity of community violence is associated with medication non-adherence, all dimensions of poor insight into illness, and several previously reported covariates such as substance use comorbidity; (2) no relationship was found between insight and adherence in this particular sample; (3) multivariate analyses showed that select covariates, along with medication adherence, and select insight domains predicted a total of 73% of the magnitude of ODV behavior in this sample. Overall, medication non-adherence explained a large amount of how violently participants behaved toward others. Since non-adherence was independent of poor insight, it may be more worthwhile for clinicians to develop treatment strategies to target medication adherence without directly addressing an elusive target such as insight into illness. Treatment addressing medication adherence needs to concomitantly target substance use behaviors since the latter was responsible for a substantial increase in ODV.     

Problem-Solving in the Nursing Home Environment: Age and Experience Differences in Emotional Reactions and Responses

This study examined age differences in the perception of problems occurring in a nursing home. A predominantly female sample (N = 120) varying in age and in exposure to nursing homes watched videotaped vignettes depicting a woman experiencing problems in a nursing home. For each vignette, research participants reported how they thought the protagonist felt, how she should respond, and how confident they would feel to respond similarly if faced with the same situation. Age, more than experience, was related to differences in perceptions, with older adults reporting that the protagonist felt sad more often than did younger adults, who perceived the protagonist as feeling angry. Younger age was associated with more action-oriented coping strategies. No age differences emerged for how well the participants felt they could handle the situation. Results suggest that nursing home employees differ from the residents in both their perceptions of the problems and recommended strategies used to deal with the problem.     

工作同盟和领悟对咨询效果的影响

为了解短程咨询中工作同盟和领悟对咨询效果的影响,以12个个案94次会谈为对象,考察工作同盟、领悟分别与会谈效果、治疗效果的关系,并考察二者共同作用于效果的方式。结果表明,咨访双方评定的工作同盟都可以正向预测会谈效果,但不能预测治疗效果;领悟与会谈有效性正相关,领悟正向预测治疗效果;咨询师评定的同盟的三个维度以领悟为中介影响其对会谈效果的评价。     

四字谜问题解决中原型启发的时间抵消与位置效应

根据顿悟的原型启发理论,通过两个实验考察原型启发的时间抵消和位置效应。实验1采用2（字谜类型）×2（原型呈现时间）混合设计,结果发现：松组块字谜的正确率显著高于紧组块字谜;原型谜面消失的正确率显著大于谜面存在的正确率。实验2采用2（原型位置）×2（字谜类型）×2（原型呈现时间）混合设计,结果不仅证明了实验1,且原型位置、字谜类型、原型呈现时间的交互作用显著,原型在靶字谜之前时,紧组块字谜上谜面消失的正确率显著大于谜面存在的正确率;原型在靶字谜之后时,松组块字谜上谜面消失的正确率显著大于谜面存在的正确率。表明字谜顿悟问题解决中存在原型的时间抵消和位置效应,二者连同任务难度共同影响问题解决。     

情绪影响创造性认知过程的神经机制

Occupational gender stereotypes and problem-solving in Italian adolescents

The first purpose of the study was to establish how Italian adolescents perceive jobs in the newly emerging economy sectors as well as more traditional jobs from gender-stereotyped and gender-segregated perspectives. The second purpose was to verify the role of problem-solving and gender in gender-role stereotyping. A total of 217 Italian high school students were involved. A questionnaire developed by Miller and Hayward was used to examine the students’ occupational gender-role stereotyping, segregation and interests. The Problem-Solving Inventory was administered to examine problem-solving. Adolescents perceived most jobs as being gender-stereotyped and -segregated. Female gender and problem-solving ability were associated with a reduced tendency to perceive jobs as gender-stereotyped.     

创造性思维四阶段的神经基础

华莱士(Wallas)四阶段论是创造性思维过程研究的重要模型, 该模型认为创造性思维包括准备期、酝酿期、明朗期、验证期。相关神经机制研究表明, 准备期主要包括题目呈现前大脑状态和静息状态的研究, 内侧额叶/ACC及颞叶构成准备期网络; 酝酿期主要包括酝酿期提示、延迟顿悟以及心智游移的相关研究, 这一阶段涉及左右脑的共同参与, 海马、腹内侧前额叶等脑区在酝酿过程中起重要作用; 现有顿悟研究反映明朗期和验证期神经活动, 前额叶、扣带回、颞上回、海马、楔叶、楔前叶、舌回、小脑等在内的脑区构成其神经基础, 其中, 扣带回、前额叶在不同角度进行的研究中均有参与, 颞上回是负责远距离联想的关键脑区, 海马参与定势打破与新颖联系形成, 外侧额叶是定势转移的关键脑区, 楔前叶、左侧额下/额中回、舌回在原型激活中起关键作用, 左外侧前额叶参与对答案细节性的验证加工。未来研究可从研究对象、研究内容、研究手段三方面加以改进, 以对创造性思维过程作更系统的探讨。     

再探猜谜作业中“顿悟”的ERP效应

采用事件相关电位(ERP)技术探讨顿悟问题（字谜）解决中提供答案后的脑内时程动态变化。结果发现,在250~400 ms内,“有顿悟”和“不理解”比“无顿悟”的ERP波形均有一个更为负向的偏移。在“有顿悟—无顿悟”和“不理解—无顿悟”的差异波中,这个负成分的潜伏期约为320 ms (N320),地形图显示,N320在中后部活动最强。进一步对“有顿悟—无顿悟”差异波作偶极子溯源分析,发现N320主要起源于扣带前回（ACC）附近。这似乎表明,N320可能反映了提供答案瞬间新旧思路之间的认知冲突,但是却不能真正揭示顿悟问题解决中思维定势的成功突破以及“恍然大悟”所对应的独特脑内时程变化
