The effects of fine motor movement and tactile stimulation on the math problem solving of students with attention problems

This study evaluated the effectiveness of fine motor physical activity with tactile stimulation during two conditions of math problem solving, visual and auditory. Eight 4th and 5th grade students with attention problems participated. Using an alternating treatments design, students solved as many math story problems as they could, presented on worksheets or verbally during two conditions, with and without tactile stimulation during 20 min. Motor behavior, recorded from videotape, and number of correctly completed word problems were measured. Results suggest that fine motor manipulation of a tactile stimulation object reduced excessive motor movement and increased task completion of students with attention problems.

Profiles in Problem Solving: Psychological Well-Being and Distress Among Persons with Diabetes Mellitus

Although social problem-solving abilities have been consistently associated with indicators of behavioral health, this work has been largely confined to tests of specific theoretical issues. Research has yet to demonstrate how the separate elements of the social problem-solving model relate to different patterns of adjustment, particularly among persons who live with chronic disease. We studied the occurrence of different profiles of social problem-solving abilities observed among persons living with diabetes mellitus. We then examined differences between clusters on measures of life satisfaction and depression. Results indicate that distinct profiles in problem-solving abilities do occur and these groupings can be distinguished by their different patterns of adjustment. Implications for theoretical models of problem solving and clinical assessment and interventions for persons with diabetes are discussed.     

科学发明中原型启发的创造性思维成分及其脑机制

目前对创造性思维的测量及神经机制的研究, 国际上大多采用发散思维任务、远距离联想测验、顿悟问题解决等任务。但这些测量工具大多停留在对非科学类问题解决的研究上, 因此生态效度和预测效度都不高。本项目在前面研究的基础上, 探讨更符合现实生活的科学发明中原型启发的创造性思维成分及机制。研究一通过两个行为实验探索原型启发能力的创造性思维成分测试的结构效度; 研究二运用大样本磁共振数据, 从脑机制上进一步验证创造性思维成分的结构效度; 研究三通过3个核磁任务态探索原型启发能力的主要创造性思维成分的脑机制; 研究四试图在高校和企业研发机构进行跟踪研究, 检验创造性思维成分测试的预测效度。通过本项目的开展, 希望开发具有更高预测效度和生态效度的用于发明创造领域的创造性测量工具。     

四字谜问题解决中原型启发的时间抵消与位置效应

根据顿悟的原型启发理论,通过两个实验考察原型启发的时间抵消和位置效应。实验1采用2（字谜类型）×2（原型呈现时间）混合设计,结果发现：松组块字谜的正确率显著高于紧组块字谜;原型谜面消失的正确率显著大于谜面存在的正确率。实验2采用2（原型位置）×2（字谜类型）×2（原型呈现时间）混合设计,结果不仅证明了实验1,且原型位置、字谜类型、原型呈现时间的交互作用显著,原型在靶字谜之前时,紧组块字谜上谜面消失的正确率显著大于谜面存在的正确率;原型在靶字谜之后时,松组块字谜上谜面消失的正确率显著大于谜面存在的正确率。表明字谜顿悟问题解决中存在原型的时间抵消和位置效应,二者连同任务难度共同影响问题解决。     

Finer Distinctions: Variability in Satisfied Older Couples’ Problem‐Solving Behaviors

This study utilized observational and self‐report data from 64 maritally satisfied and stable older couples to explore if there were meaningful differences in how couples approached marital disagreements. Using a typology approach to classify couples based on their behaviors in a 15‐minute problem‐solving interaction, findings revealed four types of couples: (1) problem solvers (characterized by both spouses’ higher problem‐solving skills and warmth), (2) supporters (characterized by both spouses’ notable warmth), (3) even couples (characterized by both spouses’ moderate problem‐solving skills and warmth), and (4) cool couples (characterized by both spouses’ greater negativity and lower problem‐solving skills and warmth). Despite the differences in these behaviors, all couples had relatively high marital satisfaction and functioning. However, across nearly all indices, spouses in the cool couple cluster reported poorer marital functioning, particularly when compared to the problem solvers and supporters. These findings suggest that even modest doses of negativity (e.g., eye roll) may be problematic for some satisfied couples later in life. The implications of these typologies are discussed as they pertain to practitioners’ efforts to tailor their approaches to a wider swath of the population.     

From the Dawn of Humanity to the 21st Century: Creativity as an Enduring Survival Skill

While the scientific investigation into creativity is a recent phenomenon, creative thinking has always been a crucial feature of humanity. The ability to creatively solve problems enabled early humans to survive and laid the foundation for the creative imagination that has resulted in our modern society. While most humans no longer face physical threats, life and work in the 21st century demands heightened creativity skills. To meet these demands, educational practices must leverage the insights and strategies gained through research into the trainability of creative thinking.     

CAN WE STILL TALK ABOUT “TRUTH” AND “PROGRESS” IN INTERDISCIPLINARY THINKING TODAY?

On a cultural level, and for Christian theology as part of a long tradition in the evolution of religion, evolutionary epistemology “sets the stage,” as it were, for understanding the deep evolutionary impact of our ancestral history on the evolution of culture, and eventually on the evolution of disciplinary and interdisciplinary reflection. In the process of the evolution of human knowledge, our interpreted experiences and expectations of the world (and of the ultimate questions we humans typically pose to the world) have a central role to play. What evolutionary epistemology also shows us is that we humans can indeed take on cognitive goals and ideals that cannot be explained or justified in terms of survival‐promotion or reproductive advantage only. Therefore, once the capacities for rational knowledge, moral sensibility, aesthetic appreciation of beauty, and the propensity for religious belief have emerged in our biological history, they cannot be explained only in biological/evolutionary terms. Finally, in this way a door is opened for seeing problem solving as a central activity of our research traditions. As philosophers of science have argued, one of the most important shared rational resources between even widely divergent disciplines is problem solving as the most central and defining activity of all research traditions. As will become clear, the very diverse reasoning strategies of theology and the sciences clearly overlap in their shared quests for intelligible problem solving, including problem solving on an empirical, experiential, and conceptual level.     

Decoding dyadic interactive nonverbal behaviour in Chinese and Australian cohorts: A novel dyadic puzzle‐solving task

The current study used a novel problem‐solving task in which the solution could only be reached via interactions between members of dyads. The study aimed to systematically examine how nonverbal interactive behaviour was related to the cultural background of the dyads, the participant's role in the dyad (viz., instructor, problem solver) and task repetition. Twenty‐one Australian dyads and 32 Chinese dyads performed the dyadic puzzle‐solving task while their interactions were video‐recorded. In each dyad, one instructor and one problem solver worked together to solve a seven‐piece puzzle. Six trials, each comprising a different puzzle, were completed. Results indicate that the Australian instructors engaged in significantly more eye gazing and displayed more hand gestures but smiled less than the Chinese instructors. The Australian problem solvers maintained longer eye gazing, displayed more hand gestures and more echoing than their Chinese counterparts. Over trials, the Chinese instructors reduced their total talking time, hand gestures, nodding behaviour and smiling during self‐talking more than the Australian instructors. Moreover, the problem solvers in the dyads from both countries significantly reduced their smiling across trials. The current study shows that nonverbal behaviours during dyadic interactions are related to one's cultural background, role in the task and task repetition.     

认知抑制——问题解决研究的新视角

抑制是一种领域一般(domain-general)的认知过程,它使儿童和成人能够抗拒习惯、自动化、诱惑、分心物或干扰从而适应存在冲突的情境(Diamond,2013)。抑制控制模型认为儿童或成人在问题解决中的失败并非是缺少相关知识与概念,而是抑制控制失败造成的。研究者采用负启动研究范式和脑成像技术在类皮杰任务、数学和科学问题解决中证实了认知抑制的作用。未来研究应把认知抑制与元认知的研究结合起来,探究认知抑制的发展轨迹及二者在问题解决中的相对重要性。同时,针对认知抑制训练的干预研究也值得重视。
