Specificity and Abstraction of Examples: Opposite Effects on Fixation for Creative Ideation

Fixation is one of the major obstacles that individuals face in creative idea generation contexts. Several studies have shown that individuals unintentionally tend to fixate to the examples they are shown in a creative ideation task, even when instructed to avoid them. Most of these studies used examples formulated with high level of specificity. However, no study has examined individuals’ creative performance under an instruction to diverge from given examples, when these examples are formulated with a high level of abstraction. In the present study, we show that (a) instructing participants to avoid using common examples when formulated with a high level of specificity increases fixation; whereas (b) instructing participants to avoid such examples while using a more abstract level for stating these common examples—such as a categorization of these examples—mitigates fixation and doubles the number of creative ideas generated. These findings give new insights on the key role of categorization in creative ideation contexts.     

团队多样性与组织支持对团队创造力的影响

采用实验法在专业异质性与群体断层两个水平上操纵团队多样性, 通过两个实验考察团队多样性与组织支持的交互作用对团队创造力的影响。研究结果表明：(1)在独创性维度上, 专业异质团队在工具支持条件下的独创性显著高于专业同质团队, 情感和物质支持条件下二者差异不显著。当团队出现群体断层时, 情感支持与工具支持具有同样的促进作用, 即在这两种组织支持下, 强断层团队的独创性显著高于弱断层团队; 物质支持条件下二者差异不显著。(2)在适宜性维度上, 组织支持的主效应显著, 两个实验一致地发现物质支持条件下的适宜性显著高于情感支持和工具支持。本研究从团队多样性与组织支持交互作用的角度考察不同复杂程度、不同组织目标的多样性团队所需要的组织支持条件, 对促进团队创造力具有一定的理论与实践价值。     

Motivated information processing, social tuning, and group creativity

The extent to which groups are creative has wide implications for their overall performance, including the quality of their problem solutions, judgments, and decisions. To further understanding of group creativity, we integrate the motivated information processing in groups model (De Dreu, Nijstad, & Van Knippenberg, 2008) with work on epistemic social tuning (Lunn, Sinclair, Whitchurch, & Glenn, 2007). Three propositions were advanced: (a) Groups produce more ideas when members have high rather than low epistemic motivation, especially when members also have a prosocial rather than pro-self motivation; (b) these ideas are more original, appropriate, or feasible when a group norm favors originality, appropriateness, or feasibility; and (c) originality is valued more in individualistic cultures (e.g., the Netherlands), whereas appropriateness is valued more in collectivist cultures (e.g., Korea). Four studies involving 3-person groups generating ideas supported these propositions: Epistemic motivation (mild vs. intense time pressure; presence vs. absence of process accountability) stimulated production and originality, especially when prosocial rather than pro-self motives were present and participants were Dutch or originality norms were experimentally primed. When appropriateness norms were primed or participants were Korean, epistemic motivation stimulated production and appropriateness, especially when prosocial rather than pro-self motives were present. We discuss implications for research on group processes and for work on culture and creativity.     

The dual pathway to creativity model: Creative ideation as a function of flexibility and persistence

The dual pathway to creativity model argues that creativity—the generation of original and appropriate ideas—is a function of cognitive flexibility and cognitive persistence, and that dispositional or situational variables may influence creativity either through their effects on flexibility, on persistence, or both. This model is tested in a number of studies in which participants performed creative ideation tasks. We review work showing that cognitive flexibility, operationalised as the number of content categories surveyed, directly relates to idea originality, but that originality can also be achieved by exploring a few content categories in great depth (i.e., persistence). We also show that a global processing mode is associated with cognitive flexibility, but only leads to high originality in tasks that capitalise on cognitive flexibility. We finally show that activating positive mood states enhance creativity because they stimulate flexibility, while activating negative mood states can enhance creativity because they stimulate persistence. Implications for theory and practice are discussed.     

Constraining or Constructive? The Effects of Examples on Idea Novelty

The tendency to conform to prior examples can be viewed as a form of mental fixation that has negative consequences and limits the scope and quality of designs. Two experiments using the Smith, S. M., Ward, T. B., & Schumacher, J. S. [(1993) Memory & Cognition, 21, 837‐845] toy invention task were conducted to determine whether participants who viewed example toys would subsequently generate toys rated as less novel compared to a control group viewing no examples. Although participants who viewed examples tended to incorporate the example features into their own ideas, the novelty of their ideas was rated as higher than those of the control group. This effect occurred both with no specific instruction regarding the examples (Experiment 1), as well as when specifically instructed to be different from the examples (Experiment 2). These results indicate that examples do not always have a negative impact on creativity, and suggest they may sometimes help lead to more unusual ideas.     

Changing the logic of replication: A case from infant studies

Among infant researchers there is growing concern regarding the widespread practice of undertaking studies that have small sample sizes and employ tests with low statistical power (to detect a wide range of possible effects). For many researchers, issues of confidence may be partially resolved by relying on replications. Here, we bring further evidence that the classical logic of confirmation, according to which the result of a replication study confirms the original finding when it reaches statistical significance, could be usefully abandoned. With real examples taken from the infant literature and Monte Carlo simulations, we show that a very wide range of possible replication results would in a formal statistical sense constitute confirmation as they can be explained simply due to sampling error. Thus, often no useful conclusion can be derived from a single or small number of replication studies. We suggest that, in order to accumulate and generate new knowledge, the dichotomous view of replication as confirmatory/disconfirmatory can be replaced by an approach that emphasizes the estimation of effect sizes via meta-analysis. Moreover, we discuss possible solutions for reducing problems affecting the validity of conclusions drawn from meta-analyses in infant research.     

The Impact of Culture on the Creative Potential of American,Russian, and Iranian College Students

This study presents evidence for the impact of sociocultural environment on creative potential. The divergent thinking performance of American, Russian, and Iranian college students was compared on the Abbreviated Torrance Test for Adults. The study revealed that, compared to the Iranians, Americans and Russians have superior abilities to consider a problem from different perspectives and to generate original solutions to a problem. The performance differences on the originality measure of the representatives of the Western and Eastern countries calls for the possible revisions of the traditional definition of creativity as a construct emphasizing originality in thinking. Although originality and innovation are inherent properties of creative behavior in the Western thought, it might have lesser value in the East.     

Another Look at Reputational Paths and Case Studies

Two studies are reported on effects of salience of identity (personal or group), comparison of performance (individual or intergroup), and dispositional self-esteem on originality of thinking. Study 1, with 169 participants, had a measure of algorithm use as the dependent variable. Significant main effect interactive effects of the predictors on algorithm use were observed. The second study had 369 participants, and a dependent measure of rated originality (novelty) of individuals' problem-solving ideas. A statistically significant three-way interaction of identity salience, comparison type, and self-esteem was observed on the originality scores. The pattern of the results across the two studies is interpreted as indicating dispositional differences in how specific situational influences on identity affect inclination toward use of algorithmic versus original problem-solving approaches. Both theoretical and applied implications of the results are offered.

Children's original thinking: an empirical examination of alternative measures derived from divergent thinking tasks

Children's creative potential is often assessed using cognitive tests that require divergent thinking, such as the Torrance Tests of Creative Thinking (TTCT; E. P. Torrance, 1974, 1976, 1990). In this study the authors investigated the effect of various scoring systems on the originality index, evaluating the high intercorrelation of fluency and originality measures found in the TTCT scoring system and the applicability of TTCT scoring norms over time and across age groups. In 3 studies, the originality of elementary school children was measured using TTCT norms and various sample-specific scoring methods with the TTCT Unusual Uses of a Box test as well as social-problem-solving tasks. Results revealed an effect of scoring technique on creativity indices as well as on the reliability of originality scores and the relationship between originality and other ability measures. The usefulness of the various measures for understanding children's original thinking are discussed.     

Creativity,Originality, and Appropriateness: What do Explicit Instructions Tell Us About Their Relationships?

Originality is a necessary part of creativity, but creative things are more than just original. They also solve a problem, or more generally are somehow fitting or appropriate. Yet previous research found an inverse relationship between ratings of originality and ratings of appropriateness. The present investigation employed a different methodology — it focused on the generation of ideas instead of judgments about them — to reexamine the relationships between originality, appropriateness, and creativity. Undergraduate students (N = 170) from two large universities received either realistic or unrealistic divergent thinking tasks. These were given with one of four types of instructions. These asked them to give (a) as many ideas as possible (which is the standard type of instruction for these kinds of tests), (b) only original ideas, (c) only appropriate ideas, or (d) only creative ideas. Brief definitions of originality, appropriateness, or creativity were also provided. Comparisons of the four groups indicated that there were significant differences between the different kinds of tasks, with the realistic set eliciting more appropriate ideas than the unrealistic, but the unrealistic tasks eliciting more original and varied (flexible) ideas. There was an interaction indicating that the magnitude of the impact of the instructions varied across tasks. Correlational analyses indicated that the correlation between the originality and appropriateness scores was the lowest among all possible inter‐index relationships (only 7% shared variance). Future research and practical implications are explored.

Studies in social influence IV: Minority influence in a context of original judgments

This research was devoted to the studv of minoritv influence in a context of originality of judgments. It was stimulated by a consideration of the role pla-ved by the normative context in influence processes. In most research, this implicitlv underlies the phenomena studied. Thus, studies of social control have naturally appealed to the objectivity context. Innovation, in the social milieu in which it is involved, frequentlv implies an originality context. We hoped to study experimentally its effects on the process of social change. To this end, five experimental conditions were created, in which the originality norm was introduced in different ways – by experimental instructions, by influencing the perception of his own creativity by each individual and by using the time factor to encourage the fuller acceptance of this norm. In each condition, a consistent minority defended a deviant response in a colour perception task (the experimental paradigm used in our previous research using an objectivity context). The originality context affected the development of minority influence. Judgment based on perceptual evidence was abandoned to a significant degree, and new influence behaviours appeared. Individuals followed the minority or avoided the conflict by apparently original compromise responses. They were able to adopt several modes of response in the destructured way during the experiment, as they could oppose the minority by adopting a counter-norm. Although these reactions depended on the way in which the originality norm was introduced, theprimary role in this process was nevertheless played by the minority, which provided the pole of attraction and persuasion in the group.     

A Latent Profile Analysis of the Criterion-related Validity of a Divergent Thinking Test

The criterion-related validity of divergent thinking (DT) tests has been questioned because of relatively low correlations between DT test scores and creative performance. A possible inhibiting factor in previous correlations—heterogeneity of the sample—has been ignored. If groups with different DT profiles are involved in this line of research, low correlations would not necessarily be indicative of actual relationships, and criterion-related validity would appear to be lower than it is. Thus, this study identified groups with their own unique DT profiles and examined their creative performance. To this end, elementary children’s (N = 325) responses in 3 DT tasks were analyzed using latent profile analysis. Results suggested 3 groups with unique DT profiles: One group scored moderate on fluency and low on originality; another group scored moderate on fluency and high on originality; the third group scored uniformly low across fluency, originality, and flexibility. Surprisingly, only the low-originality group excelled in creative achievement, but the hypothesis of this investigation was supported by the fact that only the high-originality group significantly excelled in ideation. These results confirm that low correlations between DT indices and creative performance do not necessarily indicate a lack of the criterion-related validity of DT tests. Differences between the creative achievement and the ideation criterion measures are detailed, and idiosyncratic properties in DT profiles and their corresponding creative strengths are discussed as educational implications.     

The Effects of Domain Knowledge and Instructional Manipulation on Creative Idea Generation

The experiment was designed to explore the effects of domain knowledge, instructional manipulation, and the interaction between them on creative idea generation. Three groups of participants who respectively possessed the domain knowledge of biology, sports, or neither were asked to finish two tasks: imagining an extraterrestrial animal and creating a new sport. Participants in each group were randomly assigned to one of three instructions, in order to encourage them to perform the tasks using a specific instance strategy (relying on specific instances), an abstract strategy (relying on abstract principles), or their habitual ways. Based on an analysis of the participants' verbal reports and their creations, the results suggested that domain knowledge enhanced the tendency to use the abstract strategy, and improved the originality and practicality of the generated ideas. Instructions also influenced the strategy participants used in creative idea generation. The instruction to use abstract principles brought forth the most original creations. Moreover, there was an interaction between domain knowledge and instructions. Encouraging participants to use the specific instance strategy blocked the knowledgeable people from developing novel ideas. Other factors, such as age, grade and gender, were found to be unrelated to either the originality or the practicality of the creations. The implications of the results were discussed in detail.     

Relative accessibility of domain knowledge and creativity: The effects of knowledge activation on the quantity and originality of generated ideas

In brainstorming research, quantity is assumed to breed quality. However, little is known about the cognitive mechanisms underlying this relationship. A parsimonious explanation assumes a random process, in which every idea has an equal chance of being a high-quality (original and feasible) idea. In contrast, a ‘deep exploration’ approach suggests that the originality (but not the feasibility) of generated ideas is dependent on the degree to which people engage in deep exploration of their knowledge. We conducted two experiments to test the latter hypothesis. Prior to a brainstorming task, participants were primed with subcategories of the brainstorming topic. Priming caused a higher relative productivity and average originality within the primed subcategory, but did not affect global productivity and originality across categories. This effect was replicated in dyadic interactions. These results support the deep exploration hypothesis, and suggest that the relationship between quantity and quality is more complex than has previously been assumed.     

身体姿势启动的内隐权力感对公平决策的影响

已有研究表明, 扩张身体姿势可启动个体的权力感。基于具身认知的视角, 实验1考察身体姿势对免惩罚游戏的提议者进行金钱分配时的影响, 实验2和实验3分别考察最后通牒游戏、免惩罚游戏的回应者在蜷缩和扩张姿势下对各种分配类型方案的拒绝率。结果表明, 与蜷缩姿势相比, 扩张姿势使个体更倾向于在免惩罚游戏提议者角色时做出更多的利己不公平分配, 同时使个体更倾向于拒绝最后通牒游戏和免惩罚游戏中的不公平分配。本研究证明了扩张姿势启动的权力感可影响个体的公平决策。     

先前知识和样例设计对学习分数乘法规则的影响

研究通过3个实验,以6年级学生为被试,考察了先前知识在分数乘法规则单、双内容样例学习中的作用以及“标记法”、“标记+注释法”样例设计方法对低先前知识学生学习双内容样例的促进效果。结果发现：（1）高先前知识学生学习两种样例的迁移成绩无显著差异,且均好于低先前知识学生的成绩;（2）低先前知识学生学习单内容样例的迁移成绩明显优于双内容样例;（3）与学习普通样例相比,低先前知识学生学习“标记法”双内容样例的后测成绩无显著差异,但学习“标记+注释法”设计的样例的成绩明显更好。结果表明,学生单、双内容样例的学习效果受其先前知识水平的影响;低先前知识学生未能从“标记法”设计的双内容样例中获益,但学习“标记+注释法”设计的样例效果更佳。     

动画教学代理对多媒体学习的影响:学习者经验与偏好的调节作用

以往研究发现,动画教学代理对多媒体学习效果的影响不一致,可能受到学习者特征和偏好的调节。本研究以“空调的组成部分及工作原理”为实验材料,采用两个实验控制教学代理有无、经验高低和代理偏好,探讨动画教学代理对多媒体学习的影响。实验1发现与无代理组相比,代理组对教学视频的注视点个数更多,平均眼跳潜伏期更短,学习兴趣也更高;低经验者在代理条件下的迁移成绩更好。实验2发现学习者在偏好代理和非偏好代理条件下的迁移成绩好于无代理组;偏好代理组感知到更低的认知负荷,对总体视频的注视点个数和注视频率更多,平均眼跳潜伏期更短,对学习内容的注视点个数更多。结论认为：在多媒体中加入教学代理不会减少学习者对学习内容的注意,能提高多媒体学习效果,支持社会代理理论假设;教学代理能提高低经验者的学习效果,但对高知识经验者无明显作用;加入学习者偏好的代理形象会促进学习,但加入学习者非偏好的代理形象并没有阻碍学习。
