Not only children but also adolescents and adults encounter great difficulties in learning to reason proportionally. Despite these difficulties, research increasingly shows that proportional reasoning emerges early, before it is being instructed in school. There have however been very few attempts to stimulate this early emerging ability. The aim…

Chance favors the prepared mind, said Louis Pasteur. Sometimes, significant breakthroughs occur when we creatively integrate new information, leading to a creative insight or an Aha! moment, while at other times when we fail to use a clue, we remain stuck in our habitual thinking patterns. In this study, we hypothesized that the brain's transient…

The objective of this study was to measure the contribution of the left frontopolar cortex (FPC) to analogical reasoning. Our measure of analogical reasoning derives from performance on the radiation problem, a creative problem-solving task first used in Gestalt psychology (Duncker, 1945). Success on this task is as low as 10 % without the…

Transcranial random noise stimulation (tRNS) increases performance in some perceptual tasks. However, little is known about its effect on creativity. Although dorsolateral prefrontal cortex (DLPFC) has been postulated as an important cortical area related to creativity, the relative role of left and right DLPFC is still unclear. We aimed to…

Problem-solving activities have been studied from a diversity of epistemological perspectives. In problem-solving activities, the initial tensions of a problematic situation led to a cognitive dissonance between conflicting motives and instruments to reach the activity goal. We analyze problem-solving in the continuation of Sannino and Laitinen's…

Transformational leadership has been acknowledged as an important influencing factor in knowledge management and innovation systems across a range of industries. However, there is a lack of research linking transformational leadership, knowledge sharing, and innovation within higher education, specifically within developing countries such as Iraq.…

Leadership emerges as a powerful force in the effort toward achieving quality education. The transformational leadership style inspires leaders to work toward a common goal to create change. The purpose of this basic qualitative study was to explore higher education deans' and faculty directors' perspectives on their practice of transformational…

Student modeling in intelligent tutoring systems is mostly concerned with modeling correctness of students' answers. As interactive problem solving activities become increasingly common in educational systems, it is useful to focus also on timing information associated with problem solving. We argue that the focus on timing is natural for certain…

In this article, we study the relationships between culturally existing general strategy concepts and a small information and communication technology firm's specific strategic challenge in its management team's search for a new strategy concept. We apply three theoretical ideas of cultural historical activity theory: (a) the idea of double…

Divergent thinking tasks are a popular basis for research on group creative problem solving, or brainstorming. The brainstorming literature has been dominated by research that investigates group performance by measuring the total number of generated ideas using the original rules put forth by Osborn (1953). This review of empirical literature on…

The present experiment examined whether or not the type of associations (close (e.g. apple-pear) and distant (e.g. apple-fish) word associations) and memory instruction (paying attention to the ideas of others) had effects on the idea generation performances in the brainwriting paradigm in which all participants shared their ideas by using paper…

This study evaluated the influence of the frequency of reading and writing habits (RWH) associated with education on the performance of adults in brief neuropsychological tasks. A sample of 489 Brazilian subjects, composed of 71% women, aged 21-80 years, with 2-23 years of formal education, was evaluated by the Brazilian Brief Neuropsychological…

This study examined the degree to which dimensions of parenting predicted early academic outcomes in a sample of 111 low-income African American children. Three aspects of parenting were assessed when the children were 36 months old: language stimulation, math-related stimulation, and maternal sensitivity. Academic outcomes were assessed at 54…

The remote associates test (RAT) is a complex verbal task with associations to both creative thought and general intelligence. RAT problems require not only lateral associations and the internal production of many words but a convergent focus on a single answer. Complex problem-solving of this sort may thus require both substantial verbal…

Two exploratory studies assessed the effects of an intervention on the math problem solving of students with Attention Deficit Hyperactivity Disorder (ADHD). In the first study, students were assessed on a visual task in a high stimulation classroom analog setting with and without the use of a fine motor activity. Results showed that the fine…
