Thinking Inside the Tool Box: Creativity,Constraints, and the Colossal Portraits of Chuck Close

This article presents a problem‐solving model to examine the often problematic relationship between expertise and creativity. The model has two premises, each the opposite of a common cliché. The first cliché asserts that creativity requires thinking outside‐the‐box. The first premise argues that experts can only think and problem solve inside the tool boxes of their expertise. The second cliché, that creativity requires freedom from constraints, points to the problem with expertise. Free to do anything, experts repeat what has worked best in the past. A solution is suggested by the second premise: to circumvent the liabilities of expertise, creativity requires constraints of a particular paired kind. The model is introduced as an expansion of prior process models focused on problem identification and construction. Problem‐finding is reanalyzed as constraint‐finding. A case study shows how one recognized creator, painter Chuck Close, uses constraints as a tool to solve the expertise‐creativity problem.     

How perceiving additional targets modifies teams’ tactical behavior during football small-sided games

This study aimed to measure how the change on targets information modifies teams’ tactical behavior during football small-sided games. 20 male senior professional players divided in 4 teams of 5 players participated in the study. Each team played two small-sided games, one with 2 official targets with goalkeeper and one with 6 small targets. Positional data of each player were recorded using a 15 Hz portable GPS. The distance between the centers of gravity (CG) of both team, the stretch index and the relative stretch index were measured and differences accessed via standardized differences, coefficient intervals and meta-analysis procedures. A moderate increase on the distance between the CG of each team and a small decrease on the stretch index and on the relative stretch index from 2 targets to the 6 targets games was observed. It was also identified that pitch location affected the interaction between teams. When the game was played in lateral corridors or defensive sectors, the differences between game conditions increased. Emphasizing the information for attacking team to shoot at goal, by manipulating the number of targets constrained tactical behavior of teams. The amplification of specific information on small-sided games can help coaches to promote players and teams’ emergent adapted behaviors.     

形状-宜人性的内隐联结及其对公平决策的影响

已有研究表明,形状感知与抽象概念之间具有隐喻联结并能够影响个体的判断与决策。当前研究在此基础上提出,不同形状与人格的宜人性存在关联且能够影响个体决策。实验1采用内隐联想范式的变式探讨不同形状与宜人性词汇之间的联系,结果未发现长方形和圆形与宜人性词汇存在内隐联结。实验2采用内隐联想测验探讨圆润面孔与棱角面孔与宜人性词汇之间的联系,结果发现圆润面孔与宜人词、棱角面孔与非宜人词之间存在内隐联结。实验3进一步考察形状与宜人性词汇的联结对公平决策的影响,结果发现圆润面孔更易知觉为宜人,个体更容易接受其作出的不公平分配,而棱角面孔更易知觉为非宜人,个体更容易拒绝其作出的不公平分配; 并且,宜人性感知在面孔形状与被试的接受率之间起中介作用。研究结果表明,圆润形状面孔与宜人词、棱角形状面孔与非宜人词存在隐喻联结,且这一联结能够进一步影响个体公平决策。     

Overvaluation of shape and weight among overweight children and adolescents with loss of control eating

Little is known about the phenomenology of pediatric loss of control (LOC) eating. Overvaluation of shape and weight, however, appears to be diagnostically meaningful among binge eating adults. We explored the significance of shape and weight overvaluation among children and adolescents with LOC eating. Participants (n = 526) included 149 overweight youth with LOC eating and 377 overweight controls (CON). Participants were categorized as those reporting at least moderate overvaluation (LOC-Mod, n = 74; CON-Mod, n = 106) or less than moderate overvaluation (LOC-Low, n = 75; CON-Low, n = 271), and compared on measures of eating-related and general psychopathology. LOC-Mod evidenced lower self-esteem than CON-Low, and greater behavioral problems than CON-Mod and CON-Low, but did not differ from LOC-Low in these domains. With the exception of LOC-Low and CON-Mod, all groups differed on global eating-disorder severity, with LOC-Mod scoring the highest. Overvaluation of shape and weight appears to be of questionable importance in defining subtypes of youth with LOC eating. However, as overvaluation and LOC eating each independently predicts eating-disorder onset, their confluence may confer even further risk for eating-disorder development. Longitudinal studies should address this possibility. Developmentally appropriate discussion about body image disturbance may be indicated in interventions targeting pediatric LOC eating and/or obesity.     

Exclusion constraints facilitate statistical word learning

The roles of linguistic, cognitive, and social-pragmatic processes in word learning are well established. If statistical mechanisms also contribute to word learning, they must interact with these processes; however, there exists little evidence for such mechanistic synergy. Adults use co-occurrence statistics to encode speech-object pairings with detailed sensitivity in stochastic learning environments (Vouloumanos, 2008). Here, we replicate this statistical work with nonspeech sounds and compare the results with the previous speech studies to examine whether exclusion constraints contribute equally to the statistical learning of speech-object and nonspeech-object associations. In environments in which performance could benefit from exclusion, we find a learning advantage for speech over nonspeech, revealing an interaction between statistical and exclusion processes in associative word learning.     

THE CLASSICAL CONFUCIAN POSITION ON THE LEGITIMATE USE OF MILITARY FORCE

Focusing on the thought of Mencius and Xunzi, this essay reconstructs and examines the classical Confucian position on the legitimate use of military force. It begins by sketching historically important political concepts, such as types of political leaders, politics of the kingly way versus politics of the hegemonic way, and the controversial role of lords‐protector. It then moves on to explore Confucian criteria for justifying resort to the use of force, giving special attention to undertaking punitive expeditions to interdict and punish aggression and tyranny. Following this discussion, the essay then attends to important Confucian moral constraints on how military force is properly employed, including prohibitions on attacking the defenseless, indiscriminate slaughter of enemy forces, destruction of civilian infrastructure, prisoner abuse, and non‐consensual annexation of territory. The essay concludes by first discussing an illustrative case from Mencius and then comparing its reconstruction of the Confucian position to those offered by other scholars.     

Do Programmers Prefer Predictable Expressions in Code?

Source code is a form of human communication, albeit one where the information shared between the programmers reading and writing the code is constrained by the requirement that the code executes correctly. Programming languages are more syntactically constrained than natural languages, but they are also very expressive, allowing a great many different ways to express even very simple computations. Still, code written by developers is highly predictable, and many programming tools have taken advantage of this phenomenon, relying on language model surprisal as a guiding mechanism. While surprisal has been validated as a measure of cognitive load in natural language, its relation to human cognitive processes in code is still poorly understood. In this paper, we explore the relationship between surprisal and programmer preference at a small granularity—do programmers prefer more predictable expressions in code? Using meaning-preserving transformations, we produce equivalent alternatives to developer-written code expressions and run a corpus study on Java and Python projects. In general, language models rate the code expressions developers choose to write as more predictable than these transformed alternatives. Then, we perform two human subject studies asking participants to choose between two equivalent snippets of Java code with different surprisal scores (one original and transformed). We find that programmers do prefer more predictable variants, and that stronger language models like the transformer align more often and more consistently with these preferences.     

Reducing Proactive Interference in Motor Tasks

Abstract

Changing automatized movement patterns often leads to initial performance decrements caused by proactive interference. In this study, we scrutinized whether proactive interference could be reduced by inhibiting the to-be-changed movement pattern by means of a physical movement constraint and verbal inhibition instructions, and whether any of the two interventions may be superior. Skilled typists typed short texts as fast and accurately as possible on a regular QWERTZ keyboard. After baseline measures, a new rule prohibiting the use of the left index finger was introduced. Subsequently, participants took part in either a verbal instruction or an additional motor restriction intervention phase. Results revealed that the original rule change was successful in inducing proactive interference in skilled typists. Most importantly, the two interventions similarly reduced proactive interference both immediately following the rule change and after ten practice sessions. We conclude that reducing proactive interference by means of physical motor restrictions and verbal instructions may be equally effective.
