The affective consequences of artistic and scientific problem solving

Abstract

Although the influence of affect on creativity has received some theoretical and empirical attention, the role of affect as a consequence of creative problem solving has been neglected. This study is the one of the first to examine empirically the affect that results from creative problem solving. In a 2 (group) × 3 (time period) × 2 (task) factorial design, 122 art and science students were randomly assigned to complete an art or science task and to report on the kind and intensity of affect before, during, and after creative problem solving. It was predicted that art and science students would report different levels of affect only after the insight, not before or during, and that the effects of task, not just group, would contribute to affective variability between art and science students. Science students reported similar levels of (positive) affective intensity before and during creative insight as art students. It was only after the insight that art students reported more intense affective experiences than science students. Task differences accounted for a significant amount of variance in affective intensities, but primarily for art-oriented subjects. These findings suggest that viewing affect as a dependent variable of cognition, rather than primarily as an independent variable, is a direction that would benefit the field of empirical work on cognition and emotion. Current cognitive theories of emotion offer much potential in understanding the affective consequences of creative problem solving.     

Emergence and reduction in dynamical cognitive science

This paper examines the widespread intuition that the dynamical approach to cognitive science is importantly related to emergentism about the mind. The explanatory practices adopted by dynamical cognitive science rule out some conceptions of emergence; covering law explanations require a deducibility relationship between explanans and explanandum, whereas canonical theories of emergence require the absence of such deducibility. A response to this problem - one which would save the intuition that dynamics and emergence are related - is to reconstrue the concept of emergence as a relationship between laws. I call this “nomological emergence” and comment on the extent to which dynamicists would find it acceptable. Alternatively, dynamical cognitive science might be viewed as fitting better with the kind of “functional reductionism” which has recently been developed by authors such as Jaegwon Kim. Which of these two alternatives is preferable remains an open question pending the further development of dynamical cognitive science, particularly in its “non-classical” forms.     

A Test of the Testing Effect: Acquiring Problem‐Solving Skills From Worked Examples

The “testing effect” refers to the finding that after an initial study opportunity, testing is more effective for long‐term retention than restudying. The testing effect seems robust and is a finding from the field of cognitive science that has important implications for education. However, it is unclear whether this effect also applies to the acquisition of problem‐solving skills, which is important to establish given the key role problem solving plays in, for instance, math and science education. Worked examples are an effective and efficient way of acquiring problem‐solving skills. Forty students either only studied worked examples (SSSS) or engaged in testing after studying an example by solving an isomorphic problem (STST). Surprisingly, results showed equal performance in both conditions on an immediate retention test after 5 min, but the SSSS condition outperformed the STST condition on a delayed retention test after 1 week. These findings suggest the testing effect might not apply to acquiring problem‐solving skills from worked examples.     

Artists' vulnerability to psychopathology: Towards an integrative cognitive perspective

A relationship is commonly reported between high levels of artistic creativity and mental health problems (e.g., depression or psychosis), and it is now becoming clearer that the divergent cognitive style associated with creativity has commonalities with some of the processes involved in the development and maintenance of some psychological difficulties. Our aim was to investigate the nature of this cognitive style. More specifically, we considered the profile of probabilistic reasoning and associated problem solving abilities, as both of these mechanisms have been found to be integral to major forms of clinical dysfunction. We assessed levels of creative potential, mood, probabilistic reasoning, and problem solving abilities in 66 arts and 85 science undergraduate volunteers. As predicted, art students showed higher levels of creative potential and experienced lower levels of mood than their science peers. Differences in probabilistic reasoning were observed which are in keeping with the pattern reported to be present in those suffering with psychosis in that they tended to ‘jump to conclusions’. Art students also displayed both poorer problem solving abilities and self‐appraisal of their problem solving skills. Our results extend previous findings associated with the mediating role of cognitive processes in the relationship between creativity and some forms of psychopathology. Implications for the prevention and treatment of psychological difficulties in the creative are highlighted.     

Exploring the nature of cognitive flexibility

Cognitive flexibility is an important characteristic that helps humans pursue complex tasks, such as multitasking and finding novel, adaptable solutions to changing demands. Yet it is still a poorly understood construct. After briefly reviewing several investigations of this construct in cognitive science, I propose a unified account that considers cognitive flexibility a property of the cognitive system, rather than a cognitive skill. The emergence of cognitive flexibility is dependent on two kinds of interactions: the interaction of several cognitive mechanisms, and the interaction of sensorimotor mechanisms, cognition, and context in developmental time. The quest for a comprehensive and unified account of cognitive flexibility is highly justified given its potential usefulness in fostering efficient problem solving and creativity.     

Increasing and decreasing motor and cognitive output: a model of general action and inaction goals

General action and inaction goals can influence the amount of motor or cognitive output irrespective of the type of behavior in question, with the same stimuli producing trivial and important motor and cognitive manifestations normally viewed as parts of different systems. A series of experiments examined the effects of instilling general action and inaction goals using word primes, such as "action" and "rest." The first 5 experiments showed that the same stimuli influenced motor output, such as doodling on a piece of paper and eating, as well as cognitive output, such as recall and problem solving. The last 2 experiments supported the prediction that these diverse effects can result from the instigation of general action and inaction goals. Specifically, these last 2 studies confirmed that participants were motivated to achieve active or inactive states and that attaining them decreased the effects of the primes on behavior.     

Does cognitive science show belief in god to be irrational? The epistemic consequences of the cognitive science of religion

The last 15 years or so has seen the development of a fascinating new area of cognitive science: the cognitive science of religion (CSR). Scientists in this field aim to explain religious beliefs and various other religious human activities by appeal to basic cognitive structures that all humans possess. The CSR scientific theories raise an interesting philosophical question: do they somehow show that religious belief, more specifically belief in a god of some kind, is irrational? In this paper I investigate this question and argue that CSR does not show that belief in god is irrational.     

The Moderation Role of Self‐perceived Maternal Empathy in Observed Mother–Child Collaborative Problem Solving

Based on L. S. Vygotsky's sociocultural theory, previous scaffolding studies have examined some factors associated with adjustment of parental support during collaborative problem solving. However, a factor that remains unexplored in the literature is the potential relationship between parental empathy and parental support in collaborative problem solving. The present study addresses this question through the observation of 45 preschool children and their mothers cooperating in a problem‐solving task with two levels of difficulty. Teachers rated the children's fine motor skills, and sampled mothers reported their empathy levels towards their children. Consistent with the notion of scaffolding, negative correlations were found between observed maternal verbal support (cognitive, autonomy, and emotional) and child age, and between observed maternal cognitive support and teacher reports of child motor skills. An analysis of covariance revealed significant empathy‐by‐difficulty interactions for physical and cognitive support after controlling for the effect of child motor skills. Implications of these findings are discussed in terms of the role of child motor skills and the importance of parental empathy in collaborative problem solving.

Gains in fluid intelligence after training non-verbal reasoning in 4-year-old children: a controlled, randomized study

Fluid intelligence (Gf) predicts performance on a wide range of cognitive activities, and children with impaired Gf often experience academic difficulties. Previous attempts to improve Gf have been hampered by poor control conditions and single outcome measures. It is thus still an open question whether Gf can be improved by training. This study included 4-year-old children (N = 101) who performed computerized training (15 min/day for 25 days) of either non-verbal reasoning, working memory, a combination of both, or a placebo version of the combined training. Compared to the placebo group, the non-verbal reasoning training group improved significantly on Gf when analysed as a latent variable of several reasoning tasks. Smaller gains on problem solving tests were seen in the combination training group. The group training working memory improved on measures of working memory, but not on problem solving tests. This study shows that it is possible to improve Gf with training, which could have implications for early interventions in children.     

Situated problem solving in Kashmiri carpet weaving practice

This paper discusses situated problem solving accomplished in the three constituent domains of Kashmiri carpet weaving practice viz. designing, coding and weaving. While, the designers’ problem relates to carving spatial regions on graph-sheets, the coders’ problem relates to cognitively demarcating relevant coding area in those graphs while generating code. Likewise, the weavers’ problem lies in demarcating weaving-territory on the loom, while the manufacturers’ problem relates to determining a particular spatial area for quality assessment. The paper discusses how the actors create fixed, transient and negotiable boundaries on the graph, the loom and the carpet to solve this problem of area determination and demarcation.Section 1 introduces this practice, its task domains and the problem of area determination and demarcation, Section 2 discusses the methodology, Section 3 discusses in detail the problem of area-determination in each task domain and the problem solving strategies employed by the actors using material available in their task-environments itself. In addition, the problem and resolution of area determination as encountered by the manufacturers is discussed. The paper concludes with a discussion on findings of this study with larger findings in cognitive science and accentuates the role played by situated and distributed cognition in unearthing the findings reported in this paper.     

Why we still need a mark of the cognitive

What makes a process a cognitive process? I’m not just asking for a list of cognitive processes, but for what makes an item on that list a cognitive process. Why should it be on the list? This is a question that has been ignored far too long in the domain of research calling itself cognitive science. It is time to give an answer and that is what I propose in this paper. I contrast my answer with others that have been given and defend the need against some claims in the literature that a mark of the cognitive is not needed.     

Early maternal stimulation and the development of cognitive competence and attention of preterm infants

The aim of the study was to investigate the relationship between several dimensions of maternal interactive behaviours, and cognitive development and attention in preterm infants. Of special interest was the question of whether high levels of maternal stimulation and activity may have negative consequences for the development of preterm infants. Sixty-six preterm infants and their mothers were followed longitudinally and videotaped in interaction situations at home, at the infant age of 6, 9 and 12 months. Mothers behaviours were scored on involvement, sensitive responsiveness, non-intrusiveness and level of activity. Moreover, infant cognitive status was assessed at 6, 12 and 24 months of age, using the Bayley Scales of Infant Development. Infant ability in problem solving and attention were assessed in two problem solving tasks at 18 and 24 months of age. The results showed that infant cognitive status at 12 and 24 months was best predicted by maternal involvement and infant responsiveness. No significant relationships were found between maternal interactive behaviours and infant ability in problem solving and attention. More importantly, there was no indication that high levels of maternal stimulation or intrusiveness may have a negative impact on later cognitive development and attention in preterm infants. © 1998 John Wiley & Sons, Ltd.

Cognitive Load During Problem Solving: Effects on Learning

Considerable evidence indicates that domain specific knowledge in the form of schemas is the primary factor distinguishing experts from novices in problem-solving skill. Evidence that conventional problem-solving activity is not effective in schema acquisition is also accumulating. It is suggested that a major reason for the ineffectiveness of problem solving as a learning device, is that the cognitive processes required by the two activities overlap insufficiently, and that conventional problem solving in the form of means-ends analysis requires a relatively large amount of cognitive processing capacity which is consequently unavailable for schema acquisition. A computational model and experimental evidence provide support for this contention. Theoretical and practical implications are discussed.     

The physical symbol grounding problem

This paper presents an approach to solve the symbol grounding problem within the framework of embodied cognitive science. It will be argued that symbolic structures can be used within the paradigm of embodied cognitive science by adopting an alternative definition of a symbol. In this alternative definition, the symbol may be viewed as a structural coupling between an agent’s sensorimotor activations and its environment. A robotic experiment is presented in which mobile robots develop a symbolic structure from scratch by engaging in a series of language games. In this experiment it is shown that robots can develop a symbolic structure with which they can communicate the names of a few objects with a remarkable degree of success. It is further shown that, although the referents may be interpreted differently on different occasions, the objects are usually named with only one form.     

“认知科学”与“第二代认知科学”刍议

以计算隐喻为核心假设的传统认知心理学以及联结主义心理学均不能克服离身心智（disembodied mind）的根本缺陷,当代认知心理学正面临着新的范型转换。以具身性和情境性为重要特征的第二代认知科学将日受重视,并促使认知神经科学进入新的发展阶段。作者认为在身心关系上应该坚持生理只是心理的必要条件,而非充分条件的立场,克服生理还原论的危险;应该重新审视基于二元论的生理机制这种说法;心理学传统中的科学主义和人文主义有可能在第二代认知科学强调认知情境性的基础上达成某种融合;第一代认知科学对意识的研究是不成功的,因为对知觉、注意、记忆、思维等心理过程的研究不能代替意识的研究,同时还应避免以意识内容的研究取代心理学研究的倾向。第二代认知科学中的动力系统理论关于变量（因素）之间的偶合（coupling）关系完全不同于变差分析中的变量之间的交互作用关系”,其动力系统模式可能更有助于破解意识的产生（涌现）之谜,并引发心理学研究的方法论的变革新潮。第二代认知科学的兴起将启发人们对身心关系、生理还原论、意识研究在心理学中的地位、人工智能对心智完全模拟的可能性等重大问题重新思考
