Effects of Group Training in Problem‐Solving Style on Future Problem‐Solving Performance

Seventy‐five participants from one suburban high school formed 21 teams with 3–4 members each for the Future Problem Solving Program International (FPSPI). Students were selected to participate in either the regular FPSPI or an enhanced FPSPI, where multiple group training activities grounded in problem‐solving style were incorporated into a 9‐week treatment period. An ANCOVA procedure was used to examine the difference in team responses to a creative problem‐solving scenario for members of each group, after accounting for initial differences in creative problem‐solving performance, years of experience in FPSPI, and creative thinking related to fluency, flexibility, and originality. The ANCOVA resulted in a significant difference in problem‐solving performance in favor of students in the treatment group (F(1, 57) = 8.21, p = .006, partial eta squared = .126, medium), while there were no significant differences in years of experience or creativity scores. This result led researchers to conclude that students in both groups had equivalent creative ability and that participation in the group activities emphasizing problem‐solving style significantly contributed to creative performance.     

Regressive Imagery in Creative Problem‐Solving: Comparing Verbal Protocols of Expert and Novice Visual Artists and Computer Programmers

We applied computer‐based text analyses of regressive imagery to verbal protocols of individuals engaged in creative problem‐solving in two domains: visual art (23 experts, 23 novices) and computer programming (14 experts, 14 novices). Percentages of words involving primary process and secondary process thought, plus emotion‐related words, were tabulated. Visual art protocols were higher in primary process thought and emotion‐related words; those from programming were higher in secondary process thought. Almost no main effects of expertise or interactions were found. Correlations between the measures (particularly those involving emotion‐related words) also varied as a function of task. This pattern suggests cognitive processes vary considerably across different creative problem‐solving tasks or domains, and that a more domain‐specific approach to creative cognition may be advisable. Further implications for integrating and consolidating some extant lines of creativity research are discussed.     

The effects of preference assessment type on problem behavior

Individuals with intellectual and developmental disabilities who engage in problem behavior maintained by access to tangibles may exhibit more problem behavior during certain preference assessments. We compared three common preference assessments to determine which resulted in fewer problem behaviors. The paired stimulus and multiple‐stimulus without replacement assessments produced higher rates of problem behavior than the free operant (FO) assessment, suggesting that the FO assessment may be the most appropriate assessment for individuals who engage in problem behavior maintained by access to tangibles.     

Influence of Efficacy and Resilience on Problem Solving in the United States,Taiwan, and China

This study explores factors that influence problem‐solving coping style across cultures. There was no significant difference in applying problem solving across U.S., Taiwanese, and Chinese samples. The effective predictors of problem solving in the U.S. and Chinese samples were self‐efficacy and trait resilience, respectively. In the Taiwanese sample, predictors were self‐efficacy and trait resilience. Trait resilience was found to mediate the effect of self‐efficacy on problem solving in the Taiwanese and Chinese samples. Practical implications are discussed. Este estudio explora factores que influyen en el estilo de afrontamiento a la resolución de problemas aplicado a distintas culturas. No se halló una diferencia significativa en la aplicación de resolución de problemas entre muestras estadounidenses, taiwaneses y chinas. Los predictores efectivos de la resolución de problemas en las muestras estadounidense y china fueron respectivamente la autoeficacia y los rasgos de resiliencia. En la muestra taiwanesa, los predictores fueron las autoeficacia y los rasgos de resiliencia. Se halló que los rasgos de resiliencia mediaron el efecto de la autoeficacia sobre la resolución de problemas en las muestras taiwanesa y china. Se discuten las implicaciones prácticas.     

Metacognition and low achievement in mathematics: The effect of training in the use of metacognitive skills to solve mathematical word problems

The central question underlying this study was whether metacognition training could enhance the two metacognition components—knowledge and skills—and the mathematical problem-solving capacities of normal children in grade 3. We also investigated whether metacognitive training had a differential effect according to the children's mathematics level. A total of 48 participants took part in this study, divided into an experimental and a control group, each subdivided into a lower and a normal achievers group. The training programme took an interactive approach in accordance with Schraw's (1998 Schraw, G. 1998. Promoting general metacognitive awareness. Instructional Science, 26: 113–125. [Crossref], [Web of Science ®] , [Google Scholar]) recommendation and was carried out over five training sessions. Results indicated that children in the training group had significantly higher post-test metacognitive knowledge, metacognitive skills, and mathematical problem-solving scores. In addition, metacognitive training was particularly beneficial to the low achievers. Thus metacognitive training enabled the low achievers to make progress and solve the same number of problems on the post-test as the normal achievers solved on the pre-test.     

母亲抑郁和惩罚对儿童早期问题行为的影响及父亲的保护作用

儿童早期是母亲消极情绪和行为的易感期,母亲抑郁和消极的教养行为可能导致儿童早期多方面的发展问题,而父亲的积极教养则可能对孩子的健康发展起到保护作用。本研究以184名学前儿童的父亲和母亲为被试,考察母亲抑郁情绪和惩罚行为对儿童问题行为的影响及作用机制,以及父亲积极鼓励在其中的调节作用。结果发现:(1)母亲抑郁显著预测儿童的内向问题行为,母亲惩罚显著预测内向和外向问题行为;(2)母亲抑郁完全通过其惩罚行为影响儿童的外向问题行为,部分通过惩罚影响儿童的内向问题行为;(3)父亲积极鼓励显著调节母亲抑郁对外向问题行为的影响,边缘显著调节母亲抑郁对内向问题行为的影响;父亲积极鼓励对母亲惩罚与内、外向问题行为之间的关系的调节不显著,表明积极的父亲鼓励可以缓冲母亲抑郁对儿童问题行为的影响。     

A PROBLEM-SOLVING APPROACH TO SOCIAL SKILLS TRAINING IN EMPLOYMENT SETTINGS WITH MENTALLY RETARDED YOUTH

The present study examined two approaches to teaching social behaviors to 3 developmentally disabled youths in work contexts. In one approach, a problem-solving procedure was learned and transferred to different materials. Conversational probes monitored interactions between disabled employees and their co-workers and customers. A multiple baseline design demonstrated that the training produced generalization and maintenance of the targeted social behaviors to the work settings. A second approach based on a role-playing intervention produced no substantial generalization in the work setting. A social validation questionnaire administered to co-workers supported the efficacy of the problem-solving training procedure. The efficacy of social problem-solving training was discussed in terms of sufficient exemplars, common stimuli, and self-mediations.     

On the relation between justification of solution method and correctness of solution in statistical problem solving

The relation between the justification of a choice of solution method and the correctness of that choice in statistical problem solving was investigated. In the first of two studies 16 subjects were asked to think aloud while solving two statistical problems. The results showed that an incorrect choice of solution method was more common when subjects did not justify their choice of solution as compared to when they justified their choice with domain-specific knowledge. Study 2 employed an experimental design. A group of 20 subjects were instructed to provide a justification for each choice of solution method, while another group of 20 subjects received no such instructions. The results showed no difference between the groups with respect to number of correct choices of solution method. A qualitative analysis of the justifications in the instructed group showed that the justifications for incorrect solution methods were more often incorrect than subjects' justifications for correct solution methods. The results in Study 2 suggested that the association found between incorrect choice of solution method and lack of justification in Study 1 was not in the first place due to a strategical deficiency on the part of the subjects but due to a lack of domain-specific knowledge.     

More factors than subjects,tests and treatments: An indeterminacy theorem for canonical decomposition and individual differences scaling

Some methods that analyze three-way arrays of data (including INDSCAL and CANDECOMP/PARAFAC) provide solutions that are not subject to arbitrary rotation. This property is studied in this paper by means of the triple product [A, B, C] of three matrices. The question is how well the triple product determines the three factors. The answer: up to permutation of columns and multiplication of columns by scalars—under certain conditions. In this paper we greatly expand the conditions under which the result is known to hold. A surprising fact is that the nonrotatability characteristic can hold even when the number of factors extracted is greater thanevery dimension of the three-way array, namely, the number of subjects, the number of tests, and the number of treatments.This paper is being published in place of Dr. Kruskal's presidential address to the Psychometric Society, April, 1975. Further results like those in this paper, as well as a surprising connection with an area of mathematics called arithmetic complexity theory, will be found in a more recent paper [Kruskal, in press].     

Uniqueness proof for a family of models sharing features of Tucker's three-mode factor analysis and PARAFAC/candecomp

Some existing three-way factor analysis and MDS models incorporate Cattell's “Principle of Parallel Proportional Profiles”. These models can—with appropriate data—empirically determine a unique best fitting axis orientation without the need for a separate factor rotation stage, but they have not been general enough to deal with what Tucker has called “interactions” among dimensions. This article presents a proof of unique axis orientation for a considerably more general parallel profiles model which incorporates interacting dimensions. The model, X_k=A^AD_k H^BD_k B', does not assume symmetry in the data or in the interactions among factors. A second proof is presented for the symmetrically weighted case (i.e., where^AD_k=^BD_k). The generality of these models allows one to impose successive restrictions to obtain several useful special cases, including PARAFAC2 and three-way DEDICOM. We want to express appreciation for the contributions of several colleagues: Jos M. F. ten Berge and Henk A. L. Kiers carefully went through more than one version of this article, found an important error, and contributed many improvements. J. Douglas Carroll and Shizuhiko Nishisato acted with unusual editorial preserverance and flexibility, thereby making possible the successful completion of a difficult assessment and revision process. Joseph B. Kruskal has long provided crucial mathematical insights and inspiration to those working in this area, but this is particularly true for us. His contributions to this specific article include early discussion of basic questions and careful examination of some earlier attempted proofs, finding them to be invalid. The anonymous reviewers also made useful suggestions. Some portions of this work were supported in part by a grant from the Natural Sciences and Engineering Research Council of Canada.
