Gender Differences in Problem Solving: Expectancy and Problem Context

In this study, we investigated gender differences in problem solving as a function of problem context and expectations for success. Subjects were 90 women and 56 men from introductory psychology classes who were administered a set of mathematical problems varying in gender context under male-expectancy, female-expectancy, and neutral-expectancy conditions. No significant gender differences or interaction of gender with problem context were found. However, significant effects of problem context and expectancy were found. Both male and female subjects made higher scores on female-context problems and lower scores in the female-expectancy condition. When mathematics aptitude was used as a covariate, an interaction of gender with expectancy was found. Men in the female-expectancy condition made significantly lower scores than either men or women in the male-expectancy condition.     

Problem Solving and Suicidal Behavior

Research on suicidal behavior falls into two main areas: studies that aim to identify demographic and social risk factors, and studies that aim to investigate the psychological processes mediating suicidal behavior. Within the latter approach, impaired problem-solving ability has been found to be an important variable. This paper reviews recent research focusing on problem-solving deficits and their relation to suicidal behavior and considers some of the methodological problems that arise. These findings are discussed in terms of active versus passive problem solving, state or trait factors, and the psychological processes underlying problem solving. Suggestions for further research are made, focusing on the links between suicidal behavior, problem solving, and autobiographical memory.     

Gender and Mathematical Problem Solving

The relationship between gender and mathematical problem-solving among high ability students depends on the attributes of the problem solving questions. This was evident in the present study of 12-year-olds. The children were from predominately White families. Eighty-three males and 76 females were tested in both the fall and the spring on the Fennema-Sherman Mathematics Attitudes Scales and on the Canadian Test of Basic Skills (CTBS). In the Spring, students were also tested on the GAUSS. Both the CTBS and the GAUSS measure mathematical problem solving. Among high ability students, there were gender differences on the problem-solving scale of the CTBS but not on the GAUSS, even though the GAUSS was independently rated as the more abstract and difficult of the two tests. The present study describes the implications of this for the question of the origin of gender differences in mathematics, and also looked at the relationship between attitudes toward mathematics and mathematical problem-solving performance.     

Simulating Benevolence: Obstructing Systemic Problem Solving

Traditional methods of evaluating and solving world problems are insufficient to deal with today's issues, which are complex and interconnected, and therefore cannot be understood, or solved, in isolation. The author's study aimed to better understand behaviors that impact systemic problems in the capacity-building community. The resultant theory of simulating benevolence conceptualizes a collection of behaviors where change agents undertake activities that are not in the best interest of community members. Instead, activities satisfy the need for activity, involvement, and excitement. This theory has real-world implications in the pursuit of systemic social change. In any social context, a change agent cannot merely go through the motions of change, seemingly behaving active and engaged, at the expense of those that he or she claims to help.

Suicide Ideation and Creative Problem Solving

This investigation utilized the recent technology for the assessment of creativity to examine the association between problem solving and suicide ideation. Three kinds of problem-finding and -solving tasks were administered to 81 (nonclinical) college students. One of these tasks assesses “problem generation” and was expected to be particularly informative, given that individuals considering suicide may perceive many problems but find few solutions. Results supported this expectation: Problem generation scores were significantly correlated with suicide ideation, even after stress was statistically controlled. A secondary analysis suggested that the originality and flexibility of solutions may be influenced by the particular problem an individual faces.     

On Runco's Problem Finding,Problem Solving,and Creativity

The relative significance of the "golden section" (? 0.618) and other notable proportions was investigated using a new unobtrusive methodology, a modified Fechnerian method of production. Fourteen professional painters each sketched under controlled conditions--"veridically, accurately, and realistically" (but without there being any mention of proportions)--27 complex stimuli presented as slides, thus producing a total of 378 sketches. The stimuli in the slides were (a) vase cutouts of various proportions placed in a mantelpiece context and (b) paintings by Kodama, Mondrian, and Whistler. The golden section and other significant and control proportions (a total of 120 occurrences) were identified beforehand by the researcher in the 27 stimuli. The 378 painters' sketches were subsequently measured by the researcher and two assistants to determine the accuracy with which the various proportions had been reproduced by the painters (a grand total of 1680--14 x 120--possible occurrences). The overall accuracy of rendering the proportions was found to be low for the vases and Kodama's paintings, but increased considerably for the Whistlers and Mondrians. As predicted, the accuracy of rendering the golden section increased from the vases to the Kodamas to the Whistlers and Mondrians. For the latter two, the golden section was in fact the most accurately rendered proportion, followed by 1.00 (found, for example, in the square and circle). The golden section is clearly important in art and to artists, but both its use and detection are subtle and must be pursued with great analytic care. The use of professional artists as informants and research participants may be of considerable help.     

Everyday Problem Solving and Emotion: An Adult Developmental Perspective

ABSTRACT— Despite cognitive declines that occur with aging, older adults solve emotionally salient and interpersonal problems in more effective ways than young adults do. I review evidence suggesting that older adults (a) tailor their strategies to the contextual features of the problem and (b) effectively use a combination of instrumental and emotion-regulation strategies. I identify factors of problem-solving contexts that affect what types of problem-solving strategies will be effective. Finally, I discuss how this identification of factors affects what we know about developmental differences in everyday problem-solving competence.     

Intuition and Visualization in Mathematical Problem Solving

In this article, I will discuss the relationship between mathematical intuition and mathematical visualization. I will argue that in order to investigate this relationship, it is necessary to consider mathematical activity as a complex phenomenon, which involves many different cognitive resources. I will focus on two kinds of danger in recurring to visualization and I will show that they are not a good reason to conclude that visualization is not reliable, if we consider its use in mathematical practice. Then, I will give an example of mathematical reasoning with a figure, and show that both visualization and intuition are involved. I claim that mathematical intuition depends on background knowledge and expertise, and that it allows to see the generality of the conclusions obtained by means of visualization.     

Teaching a Problem Solving Strategy to Inpatient Adolescents:

This study evaluated a recently developed program for teaching problem solving skills. Six inpatient adolescents received training in four general areas: Authority Figures; Peer Issues; Community Resources; and Alcohol and Drugs. The program featured response-specific feedback, modeling, self-monitoring, visual cues, positive reinforcement, response practice, self-correction, and individualized performance criterion levels. A multiple baseline across groups design was used in which each group (N + 3) received baseline, training, probes, and pre/post training generalization assessments. Generalization was assessed to two different sets of untrained problem situations that contained similar and dissimilar situations to those used in training. One set was assessed during probes and the other in pre/post evaluations. Both the probes and post assessment results revealed that the subjects' verbal problem solving skills had generalized to both types of situations. Furthermore, the subjects' three-month post assessment scores demonstrated partial maintenance and were comparable to those of a group of normal high school students. Issues related to these results and suggestions for future research are discussed.     

Training Insightful Problem Solving: Effects of Realistic and Puzzle-Like Contexts

Attempts to train people to be more insightful problem solvers have met with mixed success. This article reports the results of a controlled investigation on the effects of training with 40 participants who were equally divided into training and control conditions. Training consisted of 10 minutes of instruction and practice at avoiding or responding to the impasses that arise in insight problems. All participants were then tested on three types of problem, half of them receiving the problems in an artificial puzzle-like format, and half received the same problems set in a more realistic context. The results extended previous findings by indicating an impact of training on a range of puzzle-like problems, but not on the more realistic versions of problems, where performance with or without training was as good as that of puzzle-like problems after training. Future research will investigate whether the training procedure can be adapted to be effective with real-like problems and will examine the implications for training in the field.
