PROBLEM SOLVING AND THE AWARENESS OF THE MISSING PART

R aaheim , K. Problem solving and the awareness of the missing part. Scand. J. Psychol ., 1962, 3 , 129–131.—When university students were asked to solve the so-called Pea Problem, with the added instruction of first looking for the missing instrumental part, solutions were not more frequent than without this addition, although the latter may have led to a greater awareness of the reason for choosing the correct line of attack.     

大学生合作学习的问题解决过程及其对问题解决水平的影响

以认知风格为依据,将合作学习小组分为场依存同质组、场独立同质组以及异质组。通过小组对开放问题以及逻辑问题的解决,考察不同认知风格个体、不同类型小组的问题解决过程。同时考察问题解决过程对问题解决水平的影响。结果表明：（1）个体在解决不同类型问题时的过程体验不同。（2）问题解决过程在个体的认知风格和逻辑问题解决水平之间起调节作用。（3）不同类型小组的问题解决过程不同。（4）合作是影响小组合作学习效果的重要因素之一。     

SOLVING THE PROBLEM OF LOGICAL OMNISCIENCE

This paper looks at three ways of addressing probabilism's implausible requirement of logical omniscience. The first and most common strategy says it's okay to require an ideally rational person to be logically omniscient. I argue that this view is indefensible on any interpretation of ‘ideally rational’. The second strategy says probabilism should be formulated not in terms of logically possible worlds but in terms of doxastically possible worlds, ways you think the world might be. I argue that, on the interpretation of this approach that lifts the requirement of certainty in all logical truths, the view becomes vacuous, issuing no requirements on rational believers at all. Finally, I develop and endorse a new solution to the problem. This view proposes dynamic norms for reasoning with credences. The solution is based on an old proposal of Ian Hacking's that says you're required to be sensitive to logical facts only when you know they are logical facts.     

ASSOCIATIVE PROCESSES IN FALSE RECALL AND FALSE RECOGNITION

Abstract— Studying a list of words associated to a critical nonpresented word results in high rates of false recall and false recognition for that nonpresented item (Roediger & McDermott, 1995) Two experiments examined the effect of manipulating the number of associates presented on false recall and later false recognition of a nonpresented item. In Experiment 1, associate lists of varying lengths were studied, in Experiment 2, list length was held constant and the number of associates within the list was manipulated. In both experiments, the rate of critical intrusions in recall increased steadily with increasing number of associates studied Most notably, the filler words used in Experiment 2 to equate the list lengths did not affect the rate of critical intrusions, although they did depress recall of studied words. False recall and false recognition appear to be tied to the total, not the mean, associative strength of items in the list.     

PROBLEM SOLVING AND THE ABILITY TO FIND REPLACEMENTS

Problem situations of the practical construction type may be regarded as situations characterized by a 'missing part'. The solution of a problem depends on the subject's awareness of what is missing, along with his ability to find a replacement for it. Scores on a test measuring this ability are compared with performance on two practical construction problems. Subjects who are successful on the problems have a higher mean score on the 'replacement test'. Scores on a 'function-naming' test are not found to correlate with performance on the problem.     

教师解决结构不良问题策略的发展研究

以成人期个体解决结构不良问题的有关认知加工理论为框架,运用多因素设计的方法,对９０名不同年龄的教师在解决教育和教学实践中常见的三种冲突情景下使用策略的情况进行了探讨。结果发现,教师在解决结构不良问题时,从总体上说不存在年龄差异,但在处理教师与教师、教师与家长等较为复杂的冲突问题时,随着年龄的增长,更趋向于使用元认知和认识论认知策略。该研究对教师培训中如何根据不同年龄特点来进行教育机智训练有一定的理论意义和应用价值。     

换位棋问题规则的表征与解题正确率间关系的研究

本研究通过对被试求解换位棋过程的记录与分析,重点研究了问题表征在换位棋求解过程中的作用。实验结果表明：（1）正确表征问题规则是解题的必要前提.对问题规则信息的误解和遗漏,是影响解题正确率的重要因素。其中对非隐含问题规则的错误表征也占全部错误表征的很大比率。（2）“关键结构”的发现是解决换位棋的必要条件,对问题规则的错误表征影响“关键结构”的发现.（3）前置问题的解决经验对目标问题的正确表征无显著的影响作用。     

心理表征对正投影问题解决及轴测投影图再认水平的影响

借鉴内隐记忆的研究范式,采用平面、分离的正投影问题解决及其相应轴测投影图的再认任务,探讨问题表征的结构特征性对空间问题解决和再认水平的影响。实验结果表明,一般在正投影问题获得正确解决时,对其相应的、先前从未见到过的轴测投影图往往也可获得正确再认,而且基于正投影问题获得正确解决条件下的再认水平（PCC）显著地高于那些问题未得获得解决下的再认水平（PCI）。在结合被试口语记录的基础上,研究结果证明：基于正投影图上的问题解决过程是受到一个具有三维结构特性而非正投影图中二维特性心理表征的调节;并且,正是这一具有三维结构特性心理表征的建构,使得对具有相同结构特性的轴测投影图获得了更为有效的再认。     

ON THE EINSTELLUNG EFFECT IN PROBLEM SOLVING: Some critical remarks

Objections are raised to Luchins' interpretation of the Einstellung effect and his negative evaluation of this effect. It is proposed to shift the emphasis from behavior to perception. The subject does not develop a 'bad' habit, but acts according to the specific type of problem which the experienced situation seems to present. Two types of problems are distinguished: whole problems, in which the critical problems in the Einstellung experiments are perceived as application situations, and part problems, in which the critical problems are perceived as problems in their own right.     

DIRECTIONAL PREFERENCE IN PROBLEM SOLVING

The study investigated the influence of acquired directional scanning habits on two versions (horizontal versus vertical presentation of stimuli) of an inductive reasoning test by contrasting Japanese-speaking and English-speaking (Australian) groups. The developmental trend of that influence was also investigated. Subjects were Grades 1, 5 and 7 students in both groups. The results indicated that the Japanese sample scored higher on the vertical version of the experimental test, while the Australian group scored higher on the horizontal version when timed group testing was administered to the subjects. For the individually administered test without time limit, the most marked effect was with the Australian Grade 5 students who performed better on the horizontal version than on the vertical version.     

启发信息对个体顿悟问题解决影响的眼动研究

本研究以火柴棒算式问题为实验材料,采用2(问题类型:问题A、问题B)×2(启发类型:有、无)×2(认知风格:场独立型、场依存型)×5(兴趣区:第一个加数、加号、第二个加数、等号和结果)实验设计,考察顿悟问题解决时个体的眼动差异。结果发现:相对于场依存型个体,场独立型个体能够更有效地利用启发信息来减小表征变换时的心理加工负荷,进而提高加工效率;启发信息促进问题解决者对问题的表征从数值表征转变到符号表征,从而成功地产生了顿悟。     

PROBLEM SOLVING,PLANNING AND PERSONALITY*

The present study was designed to investigate student behaviour in a river-crossing problem in light of prior experience, intelligence, personality, mode of presentation and age. Ninety-six students at Year 6 and 61 students at Year 8 from schools in Australia were administered the Eysenck Junior EPQ and IVE scales, together with six cognitive tasks used to index the Luria successive and simultaneous processing and planning functional units. Each student was given a river-crossing problem presented in one of two modes and at one of two levels of difficulty. Success on the river-crossing problem was found to be independent of age, mode of presentation or prior experience on the task. There was a significant effect due to problem awareness, intelligence and empathy and a mode by success interaction. An attempt was made to group students into problem-solver ‘types’. The results were discussed in terms of the link between cognitive and affective variables and intervention programmes.     

THE CRISIS OF HISTORICISM: AND THE PROBLEM OF HISTORICAL MEANING IN NEW TESTAMENT STUDIES

The rapid rise of varieties of historicism in Germany, during the mid‐ to late‐nineteenth century, and subsequently in England and America, resulted in a radical transformation of the principles of coherence and methods of analysis within biblical studies. 1 This paper will argue that the foundational ‘subject/object’ metaphysics of historicism has been subverted over the past century. For this reason, historical positivism should no longer be accorded the status of ‘normative paradigm’ and ‘gatekeeper’ over and against other interpretive approaches. This paper next lays out five principles for a renewed practice of historical inquiry. It argues, first, that historical inquiry continues to serve a vital function within biblical studies in its ability to call attention to historical difference, and, thereby, to contribute to a strategy of resistance to ideology and to totalizing theories; second, that the traditional appeal to historical ‘context’ and ‘author’ in the interpretation of texts continues to be a useful practice – despite the provisional and constructed nature of both – as a way of taking into account extra‐lingual reference and of avoiding presentism; third, that the substitution of new ‘grand narratives’ of Christian origins in place of the (quasi‐theological) ‘historical’ narrative of traditional Christianity – under the claim of historical objectivity – should be abandoned because the very concept of ‘origins’ is the result of a literalizing of a metaphor. Such totalizing narratives always reduce history's inherent polycentricism. Fourth, I will argue that the continued use of historicism in the antiquarian attempt to reconstruct the past, disconnected from both a quest for social justice and a desire for personal self‐creation, represents a form of thought that alienates scholars from themselves and from their real material contexts. Finally, and following on the previous point, this paper submits that the practice of historical analysis has an ethical dimension by virtue of the fact that the personhood of the biblical historian is indissolubly linked to other dimensions of life including the social and ethical aspects of life. These added dimensions complicate the making of choices, which is implicit within all practices of interpretation. These five principles are here suggested as points of departure for the reconceptualization of the scope and function of historical inquiry within the discipline of New Testament studies.
