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…

The scientific approach to the study of creative problem-solving has shifted from using classic insight problems (e.g., the "Nine-dots" problem), toward sets of problems that have more robust psychometric properties, such as the Remote Associate Test (RAT). Because it is homogeneous, compact, quickly solvable, and easy to score, the RAT…

The effect of napping versus wakefulness was studied on primed and repeated Remote Associate Tests (RATs) and on divergent creativity tests. The participants were 42 students from the USA, studying international courses at a Swedish university. The hypotheses for the RATs were (1), when the correct answers were primed before the nap, the RAT…

Many important problems require consideration of multiple constraints, such as choosing a job based on salary, location, and responsibilities. We used the Remote Associates Test to study how people solve such multiply-constrained problems by asking participants to make guesses as they came to mind. We evaluated how people generated these guesses…

This study examined the impact of teaching creativity in the form of associative thinking strategies within a metacognitive framework. A representative sample of 30 university design students was selected from a larger section (N = 122) to participate in a 16-week supplemental course. Each week a new creative thinking strategy was integrated with…

Although previous research has suggested that people with subclinical levels of schizophrenic symptoms achieve a greater number of creative accomplishments, the contention that there is a creative cognitive advantage in schizotypy has received mixed support. It was hypothesized that accounting for complex relationships between (a) creative…

Incubation has long been proposed as a mechanism in creative problem solving (Wallas, 1926). A new trial-by-trial method for observing incubation effects was used to compare the forgetting fixation hypothesis with the conscious work hypothesis. Two experiments examined the effects of incubation on initially unsolved Remote Associates Test (RAT)…
