午睡剥夺对科学发明问题解决中的原型启发效应的影响

选取生态效度较高的科学发明问题材料(分为高启发量与低启发量两类),采用“1对1”和“8对8”的“学习-测试”实验范式,考察午睡剥夺对科学发明问题解决中的原型启发效应的影响.结果发现:午睡剥夺处理、范式(“1对1”和“8对8”)和材料启发量高低在原型激活率和问题解决率上主效应均显著,午睡剥夺和范式以及启发量高低在问题解决率以及原型激活率上的交互作用不显著.这一结果说明,午睡剥夺影响科学发明问题解决中的原型启发效应,这种影响是通过对启发信息应用和原型激活两个加工过程的影响而实现的.     

问题解决中顿悟的原型位置效应的fMRI研究

科学发明创造中, 人们往往对一个问题百思不得其解, 但在看到某一启发性事物(原型)时, 突然产生顿悟, 继而发现解决问题的新思路。本研究以科学发明创造问题为实验材料, 采取“先呈现问题、后呈现原型”和“先呈现原型、后呈现问题”两种范式, 探讨问题解决中顿悟的原型位置效应, 并采用fMRI技术记录大脑的BOLD信号变化。结果发现：行为结果上, “问题在先”条件下正确率显著高于“原型在先”条件; 大脑激活结果上, 问题先导条件下的原型启发的大脑机制主要表现为左侧颞中回(left middle temporal gyrus)和左侧额中回(left middle frontal gyrus)的显著激活, “原型在先”条件下, 主要激活左侧扣带回(left cingulate gyrus)、左侧中央前回(left middle frontal gyrus)。     

父母教养态度与儿童在2-4岁期间的问题行

考察父母的教养态度和儿童在2—4岁间的问题行为的发展变化。采用交叉时序滞后设计,对172名儿童从2岁起进行2年追踪,在被试2岁和4岁时,分别对他们的父母进行间卷调查。结果发现：儿童外显问题行为与父母教养态度的相互作用较强,儿童在2岁时的外显问题行为可以预测4岁时母亲的惩罚性,内隐问题行为与父母教养态度的相互作用较弱;从2岁到4岁之间,儿童外显问题行为具有较高的稳定性,内隐问题行为的稳定性相对略低,父母教养态度也都具有一定的稳定性。     

青少年感恩与问题行为的关系:学校联结的中介作用

采用青少年感恩量表、学校联结量表、青少年外化问题行为调查表和焦虑抑郁量表对1217名中学生进行调查,考察了青少年感恩与其问题行为的关系,以及学校联结的同学支持、教师支持和学校归属感三大成分在其中的系列中介作用。结果表明:(1)青少年感恩与其外化问题行为和内化问题行为(以焦虑抑郁为指标)均显著负相关;(2)学校联结三大成分在感恩与其外化和内化问题行为之间均起着系列中介作用,即感恩对青少年学校归属感既有直接影响,也通过增强同学支持和教师支持间接促进其发展,进而学校联结的三成分共同作用减少青少年的外化和内化问题行为。     

Experiencing whole type: living into the archetypal Self

Expanding on Jung’s use of the role of the superior and inferior functions, Angelo Spoto advances a new typological model based on ‘whole type’ that utilizes a typological perspective on the archetypal Self. In this new model four cognitive modes taking superior positions are developed in the first half of life and four cognitive modes taking inferior positions are encountered in the second half of life. This model indicates that type development and type dynamics take place through the holding of the tension of opposites between superior and inferior functions, helped by the transcendent function operating differently in the first and second halves of life. Specifically, in the first half of life, the transcendent function produces a tertium that moves typological development along to consolidate an ego-pattern. In the second half of life, the transcendent function takes the individual into encounters having to do with an appreciation of sacrifice, transformation, and symbol-making, as the personality advances towards a greater awareness of wholeness, by way of the inferiors.     

解决“乙肝”问题亟须“四化”

乙型病毒性肝炎是一个严重的社会问题,而不是简单的医患之间的医疗和接受医疗的问题,它涉及到医疗机构、制药厂家以及社会、家庭、婚姻、就业等很多问题。要想从根本上解决乙型病毒性肝炎所带来的诸多问题需要全社会共同努力,形成一种“社会监督法制化、诊疗方案规范化、社会关爱人性化、具体施治个性化”的格局。     

Improving assignment preference through interspersing additional problems: Brief versus easy problems

College students were exposed to a control mathematics assignment containing 16 three-digit by two-digit multiplication (3×2) problems and two experimental assignments that contained 16 equivalent 3×2 problems and six additional interspersed problems. On one experimental assignment, 4-digit plus 4-digit problems (4+4) were interspersed. On the other experimental assignment, 2-digit divided by 1-digit with whole number answers problems (2/1) were interspersed. When given a choice, significantly more students choose the 2/1 assignment over the control and 1+4 assignment. Students also ranked the 2/1 sheet as requiring less time to complete than the control or 4+4 assignment but no differences were found on assignment difficulty rankings between the 4+4 and 2/1 assignments. No differences were found on accuracy levels or rates of responding on the target 3×2 problems across assignments. Results showed that interspersing additional problems that take relatively less time to complete may be more important for altering student preference for assignments than interspersing easier problems. Discussion focuses on schedules of reinforcement and resource efficient procedures for increasing student preference for assignment without compromising curricula integrity.     

SLEEP DEPRIVATION,ALLERGY SYMPTOMS,AND NEGATIVELY REINFORCED PROBLEM BEHAVIOR

We studied the relation between the presence versus the absence of sleep deprivation or allergy symptoms and the rate and function of problem behavior. Three students whose problem behavior was negatively reinforced by escape from instruction were studied across several weeks using analogue functional analyses. Our results indicated that the extraexperimental events were associated with (a) termination of instruction functioning as a negative reinforcer, (b) increased rates of negatively reinforced problem behavior, or (c) increased rates of problem behavior across all conditions.     

A factor related to the strength of an "Aha!" experience

Abstract: It is natural to assume that the strength of an "Aha!" becomes stronger when an unexpected solution is correct. In this study, this assumption is examined experimentally through a list of possible correct solutions. In the experiment, subjects listed the possible correct solutions before solving the problems, and evaluated the strength of their "Aha!" experience after they solved the problems. It was shown that the strength of the "Aha!" experience was strongest if the correct answer had not been included in the list of possible correct solutions; if included, the strength of the "Aha!" experience corresponded to the answer's position in the list, that is, the later the correct solution listed, the stronger the feeling became. It is suggested that the strength of an "Aha!" experience can be used as an error function in the learning process.
