A large number of studies, including single case and case series studies, have shown that patients with different types of frontotemporal dementia are characterized by the emergence of artistic abilities. This led to the hypothesis of enhanced creative thinking skills as a function of these pathological conditions. However, in the last years, it has been argued that these brain pathologies lead only to an augmented “drive to produce” rather than to the emergence of creativity. Moreover, only a few studies (...) analyzed specific creative skills, such as divergent thinking, by standardized tests. This Mini-Review aimed to examine the extent to which DT abilities are preserved in patients affected by FTD. Results showed that DT abilities are altered in different ways according to the specific anatomical and functional changes associated with the diverse forms of FTD. On the one hand, patients affected by the behavioral form of FTD can produce many ideas because of unimpaired access to memory stores, but are not able to recombine flexibly the information to produce original ideas because of damages in the pre-frontal cortex. On the other hand, patients affected by the semantic variant are impaired also in terms of fluency because of the degradation of their semantic memory store. Potential implications, limitations, and future research directions are discussed. (shrink)

Currently due to the COVID-19 pandemic, young people are experiencing a decrease in self-efficacy and an increase in mental illness. Though previous studies have shown that self-efficacy and divergent thinking training are positively related, little is known about the impact of divergent thinking training on self-efficacy and emotions. Therefore, our study seeks this answer to support teenagers injured psychologically during disastrous periods. We randomly assigned 70 students to a 2 × 2 mixed design. Participants in the (...) experimental group were given a 9-day divergent thinking training with the theme of “writing down 10 novel functions of the mask,” while those in the control group spent 10 min each day recording what they ate. The self-efficacy, anxiety, depression, and stress of two groups were measured before and after training. Results showed that, compared to the control group, self-efficacy ceased decreasing while anxiety decreased for the experimental group. These findings confirm the positive effect of divergent thinking on teenagers. Implications and limitations are discussed. (shrink)

Individual differences in convergent and divergent thinking may uniquely explain variation in analogical reasoning ability. Across two studies we investigated the relative influences of divergent and convergent thinking as predictors of verbal analogy performance. Performance on both convergent thinking and divergent thinking uniquely predicted performance on both analogy selection and analogical generation tasks. Moreover, convergent and divergent thinking were predictive above and beyond creative behaviours in Study 1 and a composite measure (...) of crystallised intelligence in Study 2. Verbal analogies in Study 2 also varied in semantic distance, with results demonstrating divergent thinking as a stronger predictor of analogy generation for semantically far than for semantically near analogies. Results thus further illuminate the link between analogical reasoning and creative cognition by demonstrating convergent and di.. (shrink)

The ability to generate diverse ideas is valuable in solving creative problems ; yet, however advantageous, this ability is insufficient to solve the problem alone and requires the ability to logically deduce an assessment of correctness of each solution. Positive schizotypy may help isolate the aspects of divergent thinking prevalent in insight problem solving. Participants were presented with a measure of schizotypy, divergent and convergent thinking tasks, insight problems, and non-insight problems. We found no evidence for (...) a relationship between schizotypy and insight problem solving. Relationships between divergent thinking and insight problem solving were also surprisingly weak; however, measures of convergent thinking had a stronger relationship with problem solving. These results suggest that convergent thinking is more important than divergent thinking in problem solving. (shrink)

The present study examined gender differences in the distribution of creative abilities through the lens of the greater male variability hypothesis, which postulated that men showed greater interindividual variability than women in both physical and psychological attributes. Two hundred and six undergraduate students in Hong Kong completed two creativity measures that evaluated different aspects of creativity, including: a divergent thinking test that aimed to assess idea generation and a creative problem-solving test that aimed to assess restructuring ability. The (...) present findings extended the research of greater male variability in creativity by showing that men generally exhibited greater variance than women in the overall distribution of the creativity scores in both divergent thinking and creative problem solving, despite trivial gender differences in mean scores. The findings further enriched the discourse of the greater male variability hypothesis by showing interesting domain-specific gendered patterns: greater male variability was more likely to occur in figural forms of creativity, with larger effect sizes, when compared to the variability in verbal forms of creativity; and mixed gendered patterns were found in the upper tails of the creativity score distribution with respect to the verbal domain but not the figural one, despite greater male representation being consistently observed in the lower tail of the distribution. Possible underlying mechanisms and implications were discussed. (shrink)

Evidence suggests divergent thinking is the cognitive basis of creative thoughts. Neuroimaging literature using resting-state functional connectivity has revealed network reorganizations during divergent thinking. Recent studies have revealed the changes of network organizations when performing creativity tasks, but such brain reconfigurations may be prolonged after task and be modulated by the trait of creativity. To investigate the dynamic reconfiguration, 40 young participants were recruited to perform consecutive Alternative Uses Tasks for divergent thinking and two (...) resting-state scans were used for mapping the brain reorganizations after AUT. We split participants into high- and low-creative groups based on creative achievement questionnaire and targeted on reconfigurations of the two brain networks: default-mode network and the network seeded at the left inferior frontal gyrus because the between-group difference of AUT-induced brain activation located at the left IFG. The changes of post-AUT RSFCs indicated the prolonged effect of divergent thinking. More specifically, the alterations of RSFCIFG−AG and RSFCIFG−IPL in the high-creative group had positive relationship with their AUT performances, but not found in the low-creative group. Furthermore, the RSFC changes of DMN did not present significant relationships with AUT performances. The findings not only confirmed the possibility of brain dynamic reconfiguration following divergent thinking, but also suggested the distinct IFGN reconfiguration between individuals with different creativity levels.

The development of a `theory of mind' may not only be important for understanding the minds of others but also for using one's own mind. To investigate this supposition, forty children between the ages of three and four were given false-belief and creativity tasks. The numbers of appropriate and of original responses in the creativity test were found to correlate positively with performance on false-belief tasks. This association was robust, as it continued to be strong and significant even when age (...) and verbal intelligence were partialled out. The results support the hypothesis that the metarepresentational skills involved in theory of mind also affect the way children can access and scan their own mental repertoire beyond the areas of currently activated content (i.e. divergent thinking). With the advent of theory of mind a basic cognitive shift takes place in human development, and possibly took place in cognitive evolution. (shrink)

We attribute three major insights to Hegel: first, an understanding of the real numbers as the paradigmatic kind of number ; second, a recognition that a quantitative relation has three elements, which is embedded in his conception of measure; and third, a recognition of the phenomenon of divergence of measures such as in second-order or continuous phase transitions in which correlation length diverges. For ease of exposition, we will refer to these three insights as the R First Theory, Tripartite Relations, (...) and Divergence of Measures. Given the constraints of space, we emphasize the first and the third in this paper. (shrink)

While correctly describing the differences in current practices between experimental psychologists and economists, Hertwig and Ortmann do not provide a compelling explanation for these differences. Our explanation focuses on the fact that psychologists view the world as composed of categories and types. This discrete organizational scheme results in merely testing nulls and wider variation in observed practices in experimental psychology.

The essential role of creativity has been highlighted in several human knowledge areas. Regarding the neural underpinnings of creativity, there is evidence about the role of left dorsolateral prefrontal cortex (DLPFC) and left inferior frontal gyrus (IFG) on divergent thinking (DT) and convergent thinking (CT). Transcranial stimulation studies suggest that the left DLPFC is associated with both DT and CT, whereas left IFG is more related to DT. However, none of the previous studies have targeted both hubs (...) simultaneously and compared transcranial direct current stimulation (tDCS) and random noise stimulation (tRNS). Additionally, given the relationship between cognitive flexibility and creativity, we included it in order to check if the improvement in creativity may be mediated by cognitive flexibility. In this double-blind, between-subjects study, 66 healthy participants were randomly assigned to one of three groups (N = 22) that received a transcranial direct current stimulation (tDCS), transcranial random noise stimulation (tRNS), or sham for 20 min. The tDCS group received 1.5 mA with the anode over the left DLPFC and cathode over the left IFG. Locations in tRNS group were the same and they received 1.5 mA of high frequency tRNS (100–500 Hz). Divergent thinking was assessed before (baseline) and during stimulation with unusual uses (UU) and picture completion (PC) subtests from Torrance Creative thinking Test, whereas convergent thinking was evaluated with the remote association test (RAT). Stroop test was included to assess cognitive flexibility. ANCOVA results of performance under stimulation (controlling for baseline performance) showed that there were significant differences in PC (F = 3.35, p = 0.042, np2 = 0.10) but not in UU (F = 0.61, p = 0.546) and RAT (F = 2.65, p = 0.079) scores. Post-hoc analyses showed that tRNS group had significantly higher scores compared to sham (p = 0.004) in PC. More specifically, tRNS showed higher performance in fluency (p = 0.012) and originality (p = 0.021) dimensions of PC compared to sham. Regarding cognitive flexibility, we did not find any significant effect of any of the stimulation groups (F = 0.34, p = 0.711). Therefore, no further mediation analyses were performed. Finally, the group that received tDCS reported more adverse effects than sham group (F = 3.46, p = 0.035). Altogether, these results suggest that tRNS may have some advantages over tDCS in DT.

Freethinking seems to be desirable because the human being is seen as an independently thinking being. However, as is well known, freethinking should not be taken for granted: ideological indoctrination, manipulation and propaganda, inter alia, are versatile tools for rulers and, in consequence, regularly repeated phenomena. One of the most drastic intellectual turning points in history occurred in the seventeenth and eighteenth centuries, when the incontestable religious world view of European civilization changed along with early modern science and the (...) Age of Enlightenment. Although freethinking and religion do not have to be thought of as opposed, the period in question includes instances of complex and delicate phenomena, which in this article are termed intellectual purism and socio-intellectual control. The discussion includes how five thinkers operated in a restrictive politico-religio-theological framework and how they manifest religious deviance. (shrink)

The thesis of instrumental convergence holds that a wide range of ends have common means: for instance, self preservation, desire preservation, self improvement, and resource acquisition. Bostrom contends that instrumental convergence gives us reason to think that "the default outcome of the creation of machine superintelligence is existential catastrophe". I use the tools of decision theory to investigate whether this thesis is true. I find that, even if intrinsic desires are randomly selected, instrumental rationality induces biases towards certain kinds of (...) choices. Firstly, a bias towards choices which leave less up to chance. Secondly, a bias towards desire preservation, in line with Bostrom's conjecture. And thirdly, a bias towards choices which afford more choices later on. I do not find biases towards any other of the convergent instrumental means on Bostrom's list. I conclude that the biases induced by instrumental rationality at best weakly support Bostrom's conclusion that machine superintelligence is likely to lead to existential catastrophe. (shrink)

Two new modes of thinking have spread through systematics in the twentieth century. Both have deep historical roots, but they have been widely accepted only during this century. Population thinking overtook the field in the early part of the century, culminating in the full development of population systematics in the 1930s and 1940s, and the subsequent growth of the entire field of population biology. Population thinking rejects the idea that each species has a natural type (as the (...) earlier essentialist view had assumed), and instead sees every species as a varying population of interbreeding individuals. Tree thinking has spread through the field since the 1960s with the development of phylogenetic systematics. Tree thinking recognizes that species are not independent replicates within a class (as earlier group thinkers had tended to see them), but are instead interconnected parts of an evolutionary tree. It lays emphasis on the explanation of evolutionary events in the context of a tree, rather than on the states exhibited by collections of species, and it sees evolutionary history as a story of divergence rather than a story of development. Just as population thinking gave rise to the new field of population biology, so tree thinking is giving rise to the new field of phylogenetic biology. (shrink)

This remarkable book is about everything from echidnas to evolution, cosmology to cooking, sex and science and spirits to Schrodinger's cat. Tyson Yunkaporta looks at global systems from an Indigenous perspective. He asks how contemporary life diverges from the pattern of creation. How does this affect us? How can we do things differently? Sand Talk provides a template for living. It's about how lines and symbols and shapes can help us make sense of the world. It's about how we learn (...) and how we remember. It's about talking to everybody and listening carefully. It's about finding different ways to look at things. Most of all it's about Indigenous thinking, and how it can save the world. (shrink)

Two questions are examined (a) the differences between creative and uncreative individuals and (b) the differences between artists and scientists. It is concluded that while divergent thinking is a necessary feature of the creative process alike in art and in science the scientific intellect exemplifies more the convergent type. Contrary to what most authorities have said it is here argued that creativity depends more upon the presence of a certain inborn flair than upon personality dynamics.

Critical thinking always involves logical and metacognitive skills. However, different modes of thinking critically with regard to psychology evince diverse sensibilities, that is, different ways of envisioning what might be wrong with a project or approach and how it could be improved. Fostering critical thinking thus is about developing distinctive modes of responsiveness and discernment, of which there can be more than one type. Literature on critical thinking for psychologists can be parsed into several ideal types. (...) Critical-thinking-in-psychology texts display a sensibility that accords great legitimacy and status to forms of psychological inquiry that emulate a certain vision of the natural sciences, as well as what Max Weber called formal rationality. Texts that advocate “critical thinking about psychology” or identify themselves as “critical psychology” all argue that psychologists need to analyze and challenge fundamental assumptions that usually go unquestioned in the conventional literature, but they also diverge significantly from one another. They generally embody one or more of four distinctive sensibilities: experiential, relational, emancipatory-activist, or emancipatory-ironic. 2012 APA, all rights reserved). (shrink)

For one to simply think, philosophy as a rational investigation of truths and principles of knowledge, being, and conduct, that is, philosophy as a "science," is not required. For thinking, what requisite is a reason, a human endowment constitutive of one's intelligence. One only needs a mind to be able to think. But something more is exigent for one to think twice, is to think again, to reconsider and see something from a different perspective. To think things twice, one (...) needs a conscious apprehension of the notion of truth, a deliberate and critical engagement with principles, and a learned competency of habits of thinking that discloses the eternal freshness of reality. These are the elements that constitute philosophy not simply as a way of life, but as an academic discipline with methods and theories. Here lies philosophy's vocational relevance. Thinking things twice is not the mental disorder of indecisiveness or the unfortunate product of capriciousness. To think things twice is the stubborn instinct of human intelligence which remains restless in entrenched patterns of thought. The apprehension of the possibility of thinking things twice is the initial promise of liberation, the first step towards unshackling the mind and its powers from mental scripts that do not give birth to creativity. This explains why it is said that in the domain of philosophical discourses, questions always outlive their answers. Indeed, though philosophy, in its many faces and guises, has offered opinions, beliefs and sometimes divergent truths to the fundamental questions of life. The more important are the questions asked than the answers proffered. The convoluted transformations and shifting grounds in the history of ideas show to us how, philosophically considered, answers have no finality. (shrink)

The role of prefrontal cortex (PFC) in influencing creative thinking has been investigated by many researchers who, while succeeding in proving an effective involvement of PFC, reported suggestive but sometimes conflicting results. In order to better understand the relationships between creative thinking and brain activation in a more specific area of the PFC, we explored the role of dorsolateral PFC. We devised an experimental protocol using transcranial direct-current stimulation (tDCS). The study was based on a 3 (kind of (...) stimulation: anodal vs. cathodal vs. sham) X 2 (priming: divergent vs. convergent) design. Forty-five healthy adults were randomly assigned to one stimulation condition. Participants’ creativity skills were assessed using the Product Improvement subtest from the Torrance Tests of Creative Thinking. After 20 minutes of tDCS stimulation, participants were presented with visual images of common objects. Half of the participants were instructed to visualize themselves using the object in an unusual way (divergent priming), whereas the other half were asked to visualize themselves while using the object in a common way (convergent priming). Priming was aimed at inducing participants to adopt different attitudes toward the creative task. Afterwards, participants were asked to describe all of the possible uses of the objects that were presented. Participants’ physiological activation was recorded using a biofeedback equipment. Results showed a significant effect of anodal stimulation that enhanced creative performance, but only after divergent priming. Participants showed lower skin temperature values after cathodal stimulation, a findings which is coherent with studies reporting that, when a task is not creative or creative thinking is not prompted, people show lower levels of arousal. The involvement of dorsolateral PFC in creativity has been supported, presumably in association to shift of attention modulated by priming. (shrink)

The present paper analyzes the dialogue between Gilles Deleuze and François Jullien. We focus on three axes articulated by the idea of immanence. Firstly, we shall compare the usage of the expression “absolutization of immanence”, coined by the sinologist in order to play down transcendence in Chinese thought, which was eventually applied by Deleuze within the realm of belief in this world. Secondly, we shall examine Jullien’s critic to Deleuze on the relation between philosophy and wisdom. We sustain that even (...) if the deleuzian description presents ambivalence in the “pre-philosophical” plane of immanence, it does not entail the superiority of philosophy. Thirdly, we shall confront the divergent perspectives on immanence: Deleuze’s treatment as plan and Jullien’s conception as fonds. Finally, we shall expose the hardship to think the idea of immanence present in the work of both authors. (shrink)
