The merits of unconscious thought in creativity

Research has yielded weak empirical support for the idea that creative solutions may be discovered through unconscious thought, despite anecdotes to this effect. To understand this gap, we examined the effect of unconscious thought on two outcomes of a remote-association test (RAT): implicit accessibility and conscious reporting of answers. In Experiment 1, which used very difficult RAT items, a short period of unconscious thought (i.e., participants were distracted while holding the goal of solving the RAT items) increased the accessibility of RAT answers, but did not increase the number of correct answers compared with an equal duration of conscious thought or mere distraction. In Experiment 2, which used moderately difficult RAT items, unconscious thought led to a similar level of accessibility, but fewer correct answers, compared with conscious thought. These findings confirm and extend unconscious-thought theory by demonstrating that processes that increase the mental activation of correct solutions do not necessarily lead them into consciousness.     

Effects of working memory capacity on mental set due to domain knowledge

The present set of studies examines how working memory capacity (WMC) relates to performance on a Remote Associates Task (RAT), originally designed by Mednick as a quantifiable creative problem solving assessment. The source of fixation was manipulated across two sets of RAT items. One set was neutral with no specific fixation embedded in them, while the second set was baseball-misleading, designed so that prior knowledge of baseball would lead to an incorrect solution attempt. WMC scores were positively related to performance on RAT items in all conditions, except one. High baseball knowledge participants' WMC scores did not relate to performance on the baseball-misleading RAT. While in general WMC may lead to better RAT performance, these results suggest that when there is a candidate solution strongly activated by prior knowledge, WMC may actually lead to too much focus on the incorrect solution and exacerbate mental sets.     

Psychometric Evaluation of an Alternate Scoring for the Remote Associates Test

The Remote Associates Test (RAT; Mednick, 1962; Mednick & Mednick, 1967) is a commonly employed test of creative convergent thinking. The RAT is scored with a dichotomous scoring, scoring correct answers as 1 and all other answers as 0. Based on recent research into the information processing underlying RAT performance, we argued that the dichotomous scoring may lead to a loss of potentially relevant information. Thus, we proposed an alternate scoring based on semantic similarity between the answer given by the participant and the correct solution using Latent Semantic Analysis (LSA; Landauer & Dumais, 1997). We evaluate the psychometric properties of the alternate LSA scoring and found evidence of construct validity for the LSA scoring which was comparable to findings for the standard scoring, but not better as we would have expected. Thus, our expectations that LSA-based scoring of the RAT counteracts potential information loss were not met. However, LSA based scorings appear to be a promising alternative for hardly solvable RAT items. We conducted additional analyses comparing different RAT item types with regard to their validity as well as evaluating the information uniquely contained in the LSA scoring. Implications of all finding for existing research using RAT items are discussed.     

Computationally constructing a repository of compound remote associates test items in American English with comRAT-G

The Remote Associates Test (RAT) has been used to measure creativity, however few repositories or standardizations of test items exist, like the normative data on 144 items provided by Bowden and Jung-Beeman. comRAT is a computational solver which has been used to solve the compound RAT in linguistic and visual forms, showing correlation to human performance over the normative data provided by Bowden and Jung-Beeman. This paper describes using a variant of comRAT, comRAT-G, to generate and construct a repository of compound RAT items for use in the cognitive psychology and cognitive modeling community. Around 17 million compound Remote Associates Test items are created from nouns alone, aiming to provide control over (i) frequency of occurrence of query items, (ii) answer items, (iii) the probability of coming up with an answer, (iv) keeping one or more query items constant and (v) keeping the answer constant. Queries produced by comRAT-G are evaluated in a study in comparison with queries from the normative dataset of Bowden and Jung-Beeman, showing that comRAT-G queries are similar to the established query set.     

Thinking can cause forgetting: memory dynamics in creative problem solving

Research on retrieval-induced forgetting has shown that retrieval can cause the forgetting of related or competing items in memory (Anderson, Bjork, & Bjork, 1994). In the present research, we examined whether an analogous phenomenon occurs in the context of creative problem solving. Using the Remote Associates Test (RAT; Mednick, 1962), we found that attempting to generate a novel common associate to 3 cue words caused the forgetting of other strong associates related to those cue words. This problem-solving-induced forgetting effect occurred even when participants failed to generate a viable solution, increased in magnitude when participants spent additional time problem solving, and was positively correlated with problem-solving success on a separate set of RAT problems. These results implicate a role for forgetting in overcoming fixation in creative problem solving.     

A cognitive style approach to creative thought.

Creative thinking was explored from several approaches to further understanding of the interrelationship of perception, personality, and cognition. College students (N = 45) were administered the Group Embedded Figures Test (GEFT), the Remote Associates Test (RAT), a questionnaire concerning RAT strategy, and two self-report scales. Field independent subjects were found to be significantly (p less than .001) more creative than field dependents. Correlations between the RAT and GEFT and the self-report measures of conformity and creativity, while largely nonsignificant, were in the predicted directions. Results demonstrated that advanced strategy levels and insightful responses were significantly related to high performance on the RAT. Theoretical links between cognitive style and Piagetian concepts were discussed in regard to creative thought. Overall, these findings support the contention that the creative processes should be studied, not as isolated structures, but with relational and multifaceted emphasis.     

Cognitive Complexity in the Remote Association Test - Chinese Version

The remote association test (RAT) has been applied in various fields; however, evidence of construct validity for the original version and subsequent extensions of the RAT remains limited. This study aimed to elucidate the dimensionality and the relationship between item features and item difficulties for the RAT—Chinese Version (RAT-C) using the Rasch model and the linear logistic test model (LLTM). The revised 30-item RAT-C was administered to 475 undergraduates (263 women and 212 men) in 8 universities in Taiwan. Item features (including types of associations among stimulus words, and frequency and concreteness of target words) were recoded. The analysis found that the RAT-C measured a single latent construct, with all 30 items conforming to the Rasch model’s expectation. Furthermore, according to the LLTM analysis, most item features predicted Rasch item difficulty, suggesting that these features can explain why some items were more difficult than others and can be used to create new items with known item difficulty to tailor the difficulty level for different groups of participants in the future.     

Assessment of Personality Organization in Couple Relationships: Factorial Structure of the Inventory of Personality Organization and Incremental Validity Over Neuroticism

Summary: Creative thinking was explored from several approaches to further understanding of the interrelationship of perception, personality, and cognition. College students (N = 45) were administered the Group Embedded Figures Test (GEFT), the Remote Associates Test (RAT), a questionnaire concerning RAT strategy, and two self-report scales. Field independent subjects were found to be significantly (p < .001) more creative than field dependents. Correlations between the RAT and GEFT and the self-report measures of conformity and creativity, while largely nonsignificant, were in the predicted directions. Results demonstrated that advanced strategy levels and insightful responses were significantly related to high performance on the RAT. Theoretical links between cognitive style and Piagetian concepts were discussed in regard to creative thought. Overall, these findings support the contention that the creative processes should be studied, not as isolated structures, but with relational and multifaceted emphasis.     

Validation of the Italian Remote Associate Test

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 has been used more frequently in recent creativity studies. We applied the Item Response Theory (IRT) to develop an Italian version of this task. The final 51-item test was reliable (α = .89) and provided information over a wide range of ability levels, as revealed by the IRT analysis. The RAT correlated with five measures of creative performance: The Raven's Standard Progressive Matrices (SPM), three classic insight problems, a set of anagrams purposefully developed, the fluency and flexibility scores of the Alternative Uses Task (AUT), and the Creative Achievements Questionnaire (CAQ). The new measure provided is meant to encourage the study of creativity and problem-solving in the Italian language.     

Autonomy and control in dyads: effects on interaction quality and joint creative performance

Two studies examined interaction quality and joint performance on two creative tasks in unacquainted dyads primed for autonomy or control orientations. It was hypothesized that autonomy-primed dyads would interact more constructively, experience more positive mood, and engage the task more readily, and as a result these dyads would perform better. To test this, Study 1 primed orientation and explored verbal creative performance on the Remote Associates Task (RAT). In Study 2, dyads were primed with autonomy and control orientation and videotaped during two joint creative tasks, one verbal (RAT) and one nonverbal (charades). Videotapes were coded for behavioral indicators of closeness and task engagement. Results showed that autonomy-primed dyads felt closer, were more emotionally and cognitively attuned, provided empathy and encouragement to partners, and performed more effectively. The effects of primed autonomy on creative performance were mediated by interpersonal quality, mood, and joint engagement.     

Effects of Alcohol On Scientific Thought During the Incubation Phase of The Creative Process

The present study examined whether or not acute alcohol intoxication inhibits or facilitates the incubation phase of Wallas' (1926/1970) four-stage model of creativity. Sixty male and female participants were randomly assigned to three groups of equal size: a Control group, a Placebo group and an Alcohol group (alcohol dose: 1.0 ml of 100% alcohol/kg body weight, delivered on two occasions). It was shown that the Alcohol group produced significantly more incubations and significantly higher levels of originality. No differences between groups regarding the scientific value of the products were obtained. Possible consequences of alcohol intoxication for creative production are discussed and a theoretical framework is introduced.     

Creativity on tap 2: Investigating dose effects of alcohol on cognitive control and creative cognition

This preregistered study aimed to replicate and extend research on the role of cognitive control in creative cognition by examining dose effects of alcohol in a randomized controlled trial. A sample of 125 participants was randomly assigned to three experimental groups, either drinking alcoholic beer (BAC = 0.03 or 0.06) or drinking non-alcoholic beer (placebo-control group). Before and after the alcohol intervention, participants completed two tests of cognitive control and two established creative thinking tasks. A BAC of 0.06 led to an impairment of verbal fluency, while working memory performance was unaffected at both alcohol levels. Alcohol had no facilitative or detrimental effects on creative thinking performance, neither in terms of RAT performance, divergent thinking fluency or divergent thinking creativity. These results indicate that moderate alcohol levels have dose-dependent, selective effects on cognitive control, and that minor impairments of cognitive control do not generally increase or attenuate creative thinking performance.     

What determines creative association? Revealing two factors which separately influence the creative process when solving the Remote Associates Test

The Remote Associates Test is a well‐established measure, frequently used to assess individuals’ creative abilities, as a function of the ability to elicit remote associates. The nature of the involved associative processes is still poorly understood. This hampers a deeper understanding of the creative process, rendering it difficult to determine what factors are controlled for, when the RAT is employed. We report an experiment that sheds further light on the nature of the associative process by manipulating (a) the frequency with which a pair of items are associated as associative strength, and (b) the probability of reaching the answer given the strength and the spread. Experimental results indicate a clear and surprisingly separate influence of frequency and probability on accuracy and response times. Frequency and probability both are thus factors that need to be included in the modeling process and controlled for when using the RAT to assess creativity.     

Creativity on tap? Effects of alcohol intoxication on creative cognition

Anecdotal reports link alcohol intoxication to creativity, while cognitive research highlights the crucial role of cognitive control for creative thought. This study examined the effects of mild alcohol intoxication on creative cognition in a placebo-controlled design. Participants completed executive and creative cognition tasks before and after consuming either alcoholic beer (BAC of 0.03) or non-alcoholic beer (placebo). Alcohol impaired executive control, but improved performance in the Remote Associates Test, and did not affect divergent thinking ability. The findings indicate that certain aspects of creative cognition benefit from mild attenuations of cognitive control, and contribute to the growing evidence that higher cognitive control is not always associated with better cognitive performance.     

Normative data for Chinese compound remote associate problems

The Remote Associates Test (RAT) is a well-known measure of creativity, with each item on the RAT is composed of three unrelated stimulus words. The participant’s task is to find an answer in the form of a word that could combine with each of the stimulus words, thus forming three new actual nouns. Researchers have modified the RAT to develop compound remote associate problems that emphasize combining vocabulary to form compound words. In the field of creativity research for Mandarin speakers, the Chinese RAT has been widely applied for over 10 years. The original RAT, compound remote associate problems, and Chinese RAT have various common advantages, such as being convenient to use and having objective scoring; additionally, the development of items for certain tests is easy and satisfies the requirements of psychological assessments in terms of the quantity of items. Currently, many language editions of the RAT and compound remote associate problems already exist. In particular, the English and Italian versions of these tests already have derived normative data. Because approximately 20% of the world’s population are native Mandarin speakers, and because increasing numbers of people are choosing Mandarin as a second language, the need to increase Mandarin-language resources is growing; however, normative data for the Chinese RAT still do not exist. To address this issue, in the present study we developed Chinese compound remote associate problems and analyzed the passing rates by items, problem solving times, and various normative data, using the responses of 253 subjects in three experiments.     

Intact retention in acute alcohol amnesia

Research on alcohol amnesia has focused on memory processes that are disrupted during intoxication. The present experiment examined the possibility that certain memory processes might be resistant to the amnesic effects of alcohol. Intoxicated and sober subjects studied a list of 29 words. They were then given one of three different retention tests: free recall, identification of degraded words based on the procedure used by Warrington and Weiskrantz (1970), and yes/no recognition. As expected, free recall was significantly impaired by alcohol intoxication. In contrast, in the identification test, intoxicated subjects benefited to the same degree as sober subjects from prior exposure to the items. The two groups did not differ in immediate recognition memory. The results of the free-recall and identification tasks are similar to findings with chronic amnesic patients and suggest that perceptual fluency is not affected by alcohol, whereas elaborative processes supporting recall are particularly sensitive to disruption during intoxication. The failure to find recognition impairment at the level of intoxication used in this study distinguishes temporary alcohol amnesia from chronic amnesia.     

Chasing red herrings: Memory of distractors causes fixation in creative problem solving

Two experiments tested the red herring retrieval hypothesis, which states that fixation in creative problem solving is worse when memory for red herrings (i.e., inappropriate or incorrect solutions) is strengthened. In Experiment 1, when associations between Remote Associates Test (RAT) problem words (e.g., COTTAGE, SWISS, CAKE) and related red herring words (e.g., hut, chocolate, icing) were strengthened via repetition, an encoding variable, fixation was found to increase. In Experiment 2, when associations were formed between RAT problem contexts and red herrings, then subsequent reinstatement of problem contexts during RAT problem solving trials (as compared with showing new contexts) also worsened fixation effects. Our results add to the increasing body of research that connects memory with creative problem solving, and they suggest possible ways for overcoming fixation effects.     

Effects of Alcohol on Picture Drawing During the Verification Phase of the Creative Process

This study tested effects of acute alcohol intoxication on elaboration and revision in the verification phase of Wallas' (1926/1970) four stage model of creativity. Forty-two male and female participants were randomly assigned to three groups of equal size--a control group, a placebo group, and an alcohol group. The alcohol dose was I ml 100% alcohol/kg body weight. Participants were instructed to read a poem and to draw a picture using the poem. These pictures were judged by 2 separate panels of judges. Panel A was comprised of 3 professional artists. Panel B was comprised of 3 college art instructors. No group differences were apparent in ratings given by Panel A, but Panel B gave the work of the alcohol group low handicraft ratings. Results were interpreted as an indication that a moderate dose of alcohol inhibits certain relevant abilities during the verification phase of the creative process.     

Effects of Alcohol on Persistent Effort and Deductive Thinking During the Preparation Phase of the Creative Process

According to the four stage model of creativity (Wallas, 1926/1970) the first stage is a phase of preparation, which requires a persistent intellectual effort over time and ability to reason deductively. The present study explored whether alcohol intoxication would impair these two abilities. 42 men and women were randomly assigned to either an Alcohol, a Placebo, or a Control group. After drinking subjects completed two tests measuring persistent effort and deductive reasoning. Results indicated that the Alcohol and Placebo groups were impaired with respect to persistent effort and that the Alcohol group also was impaired with respect to deductive reasoning. Consequences for the creative production under alcohol intoxication were discussed.     

Effects of alcohol intoxication on metamemory and on retrieval from long-term memory

In a balanced-placebo design, people expected either an alcohol drink or placebo drink and consumed either alcohol (1 ml/kg) or placebo. Shortly thereafter, each person attempted to recall the answers to general-information questions (e.g., "What is the capital of Chile?"), made confidence judgments about the accuracy of recall, made feeling-of-knowing judgments on all nonrecalled items, and received a recognition test. Unanticipated outcomes included: Alcohol intoxication significantly hindered recall from long-term memory, contrary to previous conclusions that alcohol does not affect retrieval; people's expectancy of alcohol had no significant effect on memory or metamemory performance, contrary to its established effects on other kinds of performance; and alcohol intoxication produced no significant overconfidence in judgments about recall or in feeling-of-knowing judgments, contrary to the overconfidence produced in other kinds of judgments such as an intoxicated person's assessment of his driving ability. This last outcome implies that alcohol intoxication does not produce a general lowering of the threshold for confidence but rather has effects that are situation specific.
