Why Blind-Variation Selective-Retention is an Inappropriate Explanatory Framework for Creativity

Simonton is attempting to salvage the Blind Variation Selective Retention theory of creativity (often referred to as the Darwinian theory of creativity) by dissociating it from Darwinism. This is a necessary move for complex reasons outlined in detail elsewhere. However, whether or not one calls BVSR a Darwinian theory, it is still a variation-and-selection theory. Variation-and-selection was put forward to solve a certain kind of paradox, that of how biological change accumulates (that is, over generations, species become more adapted to their environment) despite being discarded at the end of each generation (that is, parents don't transmit to offspring knowledge or bodily changes acquired during their lifetimes, e.g., you don't inherit your mother's ear piercings). This paradox does not exist with respect to creative thought. There is no discarding of acquired change when ideas are transmitted amongst individuals; we share with others modified versions of the ideas we were exposed to on a regular basis.Comment: 6 page

Contextual Focus: A Cognitive Explanation for the Cultural Revolution of the Middle/Upper Paleolithic

Many elements of culture made their first appearance in the Upper Paleolithic. Previous hypotheses put forth to explain this unprecedented burst of creativity are found wanting. Examination of the psychological basis of creativity leads to the suggestion that it resulted from the onset of contextual focus: the capacity to focus or defocus attention in response to the situation, thereby shifting between analytic and associative modes of thought. New ideas germinate in a defocused state in which one is receptive to the possible relevance of many dimensions of a situation. They are refined in a focused state, conducive to filtering out irrelevant dimensions and condensing relevant ones.Comment: 6 page

Toward a Theory of Creative Inklings

It is perhaps not so baffling that we have the ability to develop, refine, and manifest a creative idea, once it has been conceived. But what sort of a system could spawn the initial seed of creativity from which an idea grows? This paper looks at how the mind is structured in such a way that we can experience a glimmer of insight or inkling of artistic inspiration.Comment: arXiv admin note: substantial text overlap with arXiv:1309.741

Why Cognitive Science is Needed for a Viable Theoretical Framework for Cultural Evolution

Although Darwinian models are rampant in the social sciences, social scientists do not face the problem that motivated Darwin's theory of natural selection: the problem of explaining how lineages evolve despite that any traits they acquire are regularly discarded at the end of the lifetime of the individuals that acquired them. While the rationale for framing culture as an evolutionary process is correct, it does not follow that culture is a Darwinian or selectionist process, or that population genetics provides viable starting points for modeling cultural change. This paper lays out step-by-step arguments as to why a selectionist approach to cultural evolution is inappropriate, focusing on the lack of randomness, and lack of a self-assembly code. It summarizes an alternative evolutionary approach to culture: self-other reorganization via context-driven actualization of potential.Comment: 7 pages (10 point font); 1 table

Conceptual Closure: How Memories are Woven into an Interconnected Worldview

This paper describes a tentative model for how discrete memories transform into an interconnected conceptual network, or worldview, wherein relationships between memories are forged by way of abstractions. The model draws on Kauffman's theory of how an information-evolving system could emerge through the formation and closure of an autocatalytic network. Here, the information units are not catalytic molecules, but memories and abstractions, and the process that connects them is not catalysis but reminding events (i.e. one memory evokes another). The result is a worldview that both structures, and is structured by, self-triggered streams of thought.Comment: 11 pages. arXiv admin note: substantial text overlap with arXiv:adap-org/990100

Modeling Cultural Dynamics

EVOC (for EVOlution of Culture) is a computer model of culture that enables us to investigate how various factors such as barriers to cultural diffusion, the presence and choice of leaders, or changes in the ratio of innovation to imitation affect the diversity and effectiveness of ideas. It consists of neural network based agents that invent ideas for actions, and imitate neighbors' actions. The model is based on a theory of culture according to which what evolves through culture is not memes or artifacts, but the internal models of the world that give rise to them, and they evolve not through a Darwinian process of competitive exclusion but a Lamarckian process involving exchange of innovation protocols. EVOC shows an increase in mean fitness of actions over time, and an increase and then decrease in the diversity of actions. Diversity of actions is positively correlated with population size and density, and with barriers between populations. Slowly eroding borders increase fitness without sacrificing diversity by fostering specialization followed by sharing of fit actions. Introducing a leader that broadcasts its actions throughout the population increases the fitness of actions but reduces diversity of actions. Increasing the number of leaders reduces this effect. Efforts are underway to simulate the conditions under which an agent immigrating from one culture to another contributes new ideas while still fitting in.Comment: 8 pages. arXiv admin note: text overlap with arXiv:1005.151

How Creative Ideas Take Shape

According to the honing theory of creativity, creative thought works not on individually considered, discrete, predefined representations but on a contextually-elicited amalgam of items which exist in a state of potentiality and may not be readily separable. This leads to the prediction that analogy making proceeds not by mapping correspondences from candidate sources to target, as predicted by the structure mapping theory of analogy, but by weeding out non-correspondences, thereby whittling away at potentiality. Participants were given an analogy problem, interrupted before they had time to solve it, and asked to write down what they had by way of a solution. Na\"ive judges categorized responses as significantly more supportive of the predictions of honing theory than those of structure mapping.Comment: Psychology Today (online).

Are Effective Leaders Creative?

This paper explains in layperson's terms how an agent-based model was used to investigate the widely held belief that creativity is an important component of effective leadership. Creative leadership was found to increase the mean fitness of cultural outputs across an artificial society, but the more creative the followers were, the greater the extent to which the beneficial effect of creative leadership was washed out. Early in a run when the fitness of ideas was low, a form of leadership that entails the highest possible degree of creativity was best for the mean fitness of outputs across the society. As the mean fitness of outputs increased a transition inevitably occurs after which point a less creative style of leadership proved most effective. Implications of these findings are discussed.Comment: 5 pages in Psychology Today (online). (2010). https://www.psychologytoday.com/blog/mindbloggling/201102/are-effective-leaders-creativ

The Silver Lining Around Fearful Living

This paper discusses in layperson's terms human and computational studies of the impact of threat and fear on exploration and creativity. A first study showed that both killifish from a lake with predators and from a lake without predators explore a new environment to the same degree and plotting number of new spaces covered over time generates a hump-shaped curve. However, for the fish from the lake with predators the curve is shifted to the right; they take longer. This pattern was replicated by a computer model of exploratory behavior varying only one parameter, the fear parameter. A second study showed that stories inspired by threatening photographs were rated as more creative than stories inspired by non-threatening photographs. Various explanations for the findings are discussed.Comment: 4 pages, Psychology Today (online). https://www.psychologytoday.com/blog/mindbloggling/201502/the-silver-lining-around-fearful-living-0 (2015

Reframing Convergent and Divergent Thought for the 21st Century

Convergent thought is defined and measured in terms of the ability to perform on tasks where there is a single correct solution, and divergent thought is defined and measured in terms of the ability to generate multiple different solutions. However, this characterization of them presents inconsistencies, and despite that they are promoted as key constructs of creativity, they do not capture the capacity to reiteratively modify an idea in light of new perspectives arising out of an overarching conceptual framework. Research on formal models of concepts and their interactions suggests that different creative outputs may be projections of the same underlying idea at different phases of this kind of 'honing' process. This leads us to redefine convergent thought as thought in which the relevant concepts are considered from conventional contexts, and divergent thought as thought in which they are considered from unconventional contexts. Implications for the assessment of creativity are discussed.Comment: 7 pages; 2 figures
