THE ACQUISITION OF GRAPHEME‐PHONEME CORRESPONDENCES IN A WORD LEARNING TASK

Abstract

The relationship between reading ability with receptive vocabulary level and the ability to induce grapheme‐phoneme relationships was investigated using grade one students. The ability to induce relationships was assessed by a word learning task in which the stimuli were six consonant‐vowel‐consonant trigrams composed of seven letter‐like forms with a 1:1 grapheme‐phoneme correspondence. The word learning task was followed by a test of each student's acquisition of the grapheme‐phoneme correspondences that appeared in the word stimuli. The ability to induce the relationships was found to be much more strongly related to reading ability than receptive vocabulary. The results suggest that good and poor readers applied different word learning strategies, with good readers appearing to apply more readily a principled solution and poor readers an associative solution. The results are consistent with the theory of reading acquisition advanced by Gibson and Levin.     

THE EFFECTS OF GOAL-CONTINGENT PAYMENT ON THE PERFORMANCE OF A COMPLEX TASK1

Using a highly complex, computerized decision-making task, 56 university students participated in a six-week long, repeated measures, goal-setting project, involving different payment systems. Results indicated that goal-contingent payment is superior to hourly payment in influencing performance, even though the perceived valence of payment and the actual amount paid is substantially less. Discussion pointed out the limitations of the findings, including some basic equivocality in determining why such results were obtained. Discussion then focused on the implications of the findings for future investigations.     

INDIVIDUAL PERFORMANCES IN A SINGLE-CUE PROBABILITY LEARNING TASK

B jörkman , M. Individual performances in a single-cue probability learning task. Scand. J. Psychol . 1969, 10 , 113–123. —Inference behavior was studied in a 2 times 2 cue-criterion task. Fifty subjects were distributed on five conditions varying in cue validity and base rate. They were studied individually with respect to four cognitive strategies: matching, maximizing, double matching and differential maximizing. The utilization coefficients of the average subject had a tendency to 'overshoot' when the cue validity was high and to 'undershoot' when the validity was low. Double matching and differential maximizing were the most common strategies. Cognitive activity is interpreted as a compromise between various type performances.     

THE EFFECTS OF DIFFERENTIAL GOAL WEIGHTS ON THE PERFORMANCE OF A COMPLEX FINANCIAL TASK

This study involved taking goal-setting research in a new direction. Its purpose was to determine whether people could attain outcomes on a complex task that would be in line with differential goal weights corresponding to different aspects of the task. One hundred twenty-nine bank lending officers were run through a four-period, lender-simulation exercise. Teams of two to six persons competed with two to five other teams in terms of five weighted performance goals: portfolio yield, portfolio size, net income, net charge-offs, and credit file deficiencies. Weights for each performance goal were equal for each team in Periods 1 and 2. In Period 3 teams could set their own goal weights within a range. During this period goal weights were significantly related to performance for three of four relevant criteria. In all but Period 4 each group had to maintain a minimum return on assets (ROA) standard or suffer penalties. In Period 4, when the ROA standard became inoperative, ROA performance decreased significantly. These results confirm the effectiveness of goal setting (1) with complex tasks, (2) using the group as the unit of analysis, and (3) using multiple goals with differential weights.

STRATEGY MODIFICATION IN CONCEPT LEARNING AS A FUNCTION OF INTRADIMENSIONAL VARIABILITY

LINDAHL, M.-B. Strategy modification in concept learning as a function of intradimensional variability. Scand. J. Psychol. , 1971, 12, 90–98.–60 subjects took part in a concept-learning-like task, where the independent variable was the intradimensional variability of the instances and the dependent variable was the type of strategy adopted by the subjects. Two main types of strategy were used by the subjects: one based on subtle cues and in principle requiring only one instance to lead to solution (conceptual-deductive strategy) and one based on salient cues and requiring a number of instances for solution (perceptual-inductive strategy). Adoptions of a conceptual-deductive type of strategy were shown to be significantly more frequent, when the variability was large than when it was small. It was concluded that the intradimensional variability of the instances influenced the subjects' choice of strategy in a seemingly rational way. This type of strategy modification was considered to be in line with theories describing concept learning as a sequence of, in principle, rational decisions.     

分布式群体在动态系统控制决策中的内隐学习

采用计算机网络模拟技术,考察分布式群体在动态系统控制决策过程中对系统规则的内隐学习效应及其迁移。结果表明,在决策者的显性规则知识量极少且没有增加的情况下,决策绩效随决策进程适应性提高。决策者所能报告的规则知识量与决策绩效的相关也不显著。同时,当决策任务目标转换时,决策的高绩效得以维持。这表明群体决策者能对动态系统规则进行内隐学习,且能正迁移到类似的决策情景中。研究进一步指出,群体决策行为的动态适应与内隐过程有关。     

QUANTUM REALITY,THE EMERGENCE OF COMPLEX ORDER FROM VIRTUAL STATES,AND THE IMPORTANCE OF CONSCIOUSNESS IN THE UNIVERSE

Abstract. I review some characteristic aspects of quantum reality and make the connection to Pierre Teilhard de Chardin's vision and a generally new quantum perspective of biological evolution. The quantum phenomena make it possible to conclude that the basis of the material world is nonmaterial; that the nature of reality is that of an indivisible wholeness; and that elementary particles possess aspects of consciousness in a rudimentary way. The quantum perspective of evolution makes it possible to conclude that the emergence of complex order in the biosphere is not from nothing (ex nihilo) but by the actualization of virtual quantum states—that is, by actualizing empty states which are part of the mathematical structure of material systems, representing a logical order that is not real in a material sense but, predetermined by system conditions, has the potential to become real in quantum jumps. I show how the existence of virtual states makes it possible to suggest that a transcendent reality underlies the visible order of the world and is immanent to it; and constantly new forms evolve from it.     

智力和元认知技能在发现学习中的作用:任务复杂性的影响

采用自编的计算机模拟发现学习任务,以49名大学生为被试,探讨了在简单和复杂发现学习任务中,智力、元认知技能和学习成绩三者之间的关系。结果发现:在简单任务中,三者关系基本符合混合模型;进行过多的元认知活动,并不能提高学习效果。在复杂任务中,智力对学习成绩起主要预测作用。随着任务复杂性的增加,智力对学习的影响也随之变化,符合难度阈限理论的假设。任务复杂性不同时,智力、元认知技能和发现学习成绩之间的关系也不同,在一定程度上验证了难度阈限扩展理论。     

猜谜作业中顿悟的ERP效应

采用事件相关电位(ERP)探索问题解决过程中顿悟的神经机制。以猜谜作业为实验程序,对“有顿悟”和“无顿悟”答案引发的脑电分别进行叠加和平均,并将二者相减（有顿悟-无顿悟）得到差异波。在250~500 ms “有顿悟”比“无顿悟”的ERP波形有一个更加负性的偏移,在差异波中,这个负成分的潜伏期约为380 ms（N380）。地形图和电流密度图显示,N380在额中央区活动最强。偶极子源定位分析结果显示,N380可能起源于扣带前回。因此,N380可能反映顿悟问题解决过程中思维定势的突破。     

MELODY: IMPORTANCE IN LEARNING ORAL AND BOOK LANGUAGE

This paper reviews the concept that the melodic features of language play a major role in the child's acquisition of both oral and book language. The first linguistic features learned by children when acquiring oral language are the melodic or rhythmic structures (stress, intonation and juncture) and these features are learned before the phonemic. Therefore, it is feasible to claim that the melodic features of book language are learned before awareness of print. Exposure to text language read aloud and instructional methods, such as, repeated readings may supply the necessary experiential background needed to learn the rhythmic rule system of the text.

THE ROLE OF TASK AND CONTEXT IN PREFERENCE MEASUREMENT

Abstract— The present studies show that preferences change systematically depending on the global context and the measurement task Subjects evaluated apartments described by monthly rent and distance to campus using two different tasks (choices and attractiveness ratings) in two different global contexts (one with a narrow range of rents and a wide range of distances, and the other with a wide range of rents and a narrow range of distances) With the task held constant, preference orders for the same pair of apartments reversed in the two different contexts Similarly, with the context held constant, preference orders for the same pair of apartments reversed in the two tasks Taken together, the effects are startling Out of 25 apartments common to all four conditions, the preference rank of the apartment that was most expensive and closest to campus ranged from the 28th percentile to the 80th percentile We argue that, in the present experiments, the global context influences the scale values (or the perceptions of the attributes), and the task influences the weights (or the psychological importance) of the attributes.     

在内隐学习条件下任务难度对于判断准确率的影响

本研究利用自行设计的复杂规则产生出不同难度的任务系统,进而通过实验阐明了内隐学习的三个特征;（一）在任务难度极大的情况下,内隐学习并不发挥作用;（二）在任务难度降低到一定程度的时间,内隐学习开始发挥作用,这仿佛是一个“阈限”;（三）随着任务难度逐渐降低,内隐学习的效率也随着提高,但是最科停止在一个较高的水平而再继续上升,可以间接推断,内隐学习获得了样例的具体信息。
