Some problems rarely discussed in traditional philosophy of science are mentioned: The empirical sciences using mathematico-quantitative theoretical models are frequently confronted with several types of computational problems posing primarily methodological limitations on explanatory and prognostic matters. Such limitations may arise from the appearances of deterministic chaos and (too) high computational complexity in general. In many cases, however, scientists circumvent such limitations by utilizing reductional approximations or complexity reductions for intractable problem formulations, thus constructing new models which are computationally tractable. Such activities are compared with reduction types (more) established in philosophy of science. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

The global “problématique humaine” is described in terms of the “grand issues” of population, resources, development in the rich and poor countries, and the environment. Three competing paradigms about the future and their implications for the Canadian communities are examined, and a model is offered showing interrelationships between the different Canadian communities, organizational levels, and various societal/environmental activities. A comprehensive programme of future‐oriented studies is proposed.

This article is a shortened version of a monograph to appear as one of a series entitled Queen's Studies of the Future of the Canadian Communities, published by the Institute of Intergovernmental Relations, Queen's University, Kingston, Ontario. The research was funded by the Donner Canadian Foundation.  相似文献

Humans are sensitive to complexity and regularity in patterns (Falk & Konold, 1997; Yamada, Kawabe, & Miyazaki, 2013). The subjective perception of pattern complexity is correlated to algorithmic (or Kolmogorov-Chaitin) complexity as defined in computer science (Li & Vitányi, 2008), but also to the frequency of naturally occurring patterns (Hsu, Griffiths, & Schreiber, 2010). However, the possible mediational role of natural frequencies in the perception of algorithmic complexity remains unclear. Here we reanalyze Hsu et al. (2010) through a mediational analysis, and complement their results in a new experiment. We conclude that human perception of complexity seems partly shaped by natural scenes statistics, thereby establishing a link between the perception of complexity and the effect of natural scene statistics.  相似文献

Integrative complexity is a conceptually unique and very popular measurement of the complexity of human thought. We believe, however, that it is currently being underutilized because it takes quite a bit of time to score. More time‐efficient computer‐based measurements of complexity that are currently available are correlated with integrative complexity at fairly low levels. To help fill in this gap, we developed a novel automated integrative complexity system designed specifically from the integrative complexity theoretical framework. This new automated IC system achieved an alpha of .72 on the standard integrative complexity coding test. In addition, across nine datasets covering over 1,300 paragraphs, this new automated system consistently showed modest relationships with human‐scored integrative complexity (average alpha = .62; average r = .46). Further analyses revealed that this relationship consistently remained significant when controlling for superficial markers of complexity and that the new system accounted for both the differentiation and integration components of integrative complexity. Although the overlap between the automated and human‐scored systems is only modest (and thus suggests the continued usefulness of human scoring), it nonetheless provides the best automated integrative complexity measurement to date.  相似文献

The development of the unique, hierarchical, and endless combinatorial capacity in a human language requires neural maturation and learning through childhood. Compared with most non-human primates, where combinatorial capacity seems limited, chimpanzees present a complex vocal system comprising hundreds of vocal sequences. We investigated how such a complex vocal system develops and the processes involved. We recorded 10,929 vocal utterances of 98 wild chimpanzees aged 0–55 years, from Taï National Park, Ivory Coast. We developed customized Generalized non-Linear Models to estimate the ontogenetic trajectory of four structural components of vocal complexity: utterance length, diversity, probability of panting (requiring phonation across inhalation and exhalation), and probability of producing two adjacent panted units. We found chimpanzees need 10 years to reach adult levels of vocal complexity. In three variables, the steepest increase coincided with the age of first non-kin social interactions (2–5 years), and plateaued in sub-adults (8–10 years), as individuals integrate into adult social life. Producing two adjacent panted units may require more neuromuscular coordination of the articulators, as its emergence and steepest increase appear later in development. These results suggest prolonged maturational processes beyond those hitherto thought likely in species that do not learn their vocal repertoire. Our results suggest that multifaceted ontogenetic processes drive increases in vocal structural complexity in chimpanzees, particularly increases in social complexity and neuro-muscular maturation. As humans live in a complex social world, empirical support for the “social complexity hypothesis” may have relevance for theories of language evolution.

Research Highlights

  • Chimpanzees need around 10 years to develop the vocal structural complexity present in the adult repertoire, way beyond the age of emergence of every single vocal unit.
  • Multifaceted ontogenetic processes may drive increases in vocal structural complexity in chimpanzees, particularly increases in social complexity and neuro-muscular maturation.
  • Non-linear increases in vocal complexity coincide with social developmental milestones.
  • Vocal sequences requiring rapid articulatory change emerge later than other vocal sequences, suggesting neuro-muscular maturational processes continue through the juvenile years.

Integrative complexity reflects the degree to which the source of a communication perceives several dimensions and points of view relevant to the topic (differentiation) and the degree to which such characteristics are seen as related to each other (integration). During international crises, bilateral decreases in the integrative complexity of communications frequently precede the outbreak of war; a unilateral decrease reliably precedes surprise strategic attacks. In the current study, complexity was scored in the messages of selected leaders from before to approximately a month after the terrorist attacks of 11 September 2001. Even this limited database replicated some of the complexity patterns found previously, as well as showing some novel characteristics. This was the first application of the method to hostilities other than inter–nation or civil wars.  相似文献

Conway, Conway, Gornick, and Houck (2014) report a major effort to automate integrative complexity coding. Judging this effort requires researchers to be more explicit in articulating key methodological assumptions about the coding process and theoretical assumptions about the construct. Unresolved issues include: (1) when, and on what basis, we should attribute divergences between human coders and algorithms to overestimations or underestimations by one or the other approach; and (2) to what extent second‐generation algorithms can yield Pareto improvements that reduce errors of both underestimation and overestimation. Further progress in developing natural language processing measures of this cognitive style will require sharper definitions of target constructs: in particular, different types of differentiation (dialectical and elaborative) and integration (hierarchical and flexible) and clearer guidelines for factoring context into assessments.  相似文献

Prior research suggests that liberals are more complex than conservatives. However, it may be that liberals are not more complex in general, but rather only more complex on certain topic domains (while conservatives are more complex in other domains). Four studies (comprised of over 2,500 participants) evaluated this idea. Study 1 involves the domain specificity of a self‐report questionnaire related to complexity (dogmatism). By making only small adjustments to a popularly used dogmatism scale, results show that liberals can be significantly more dogmatic if a liberal domain is made salient. Studies 2–4 involve the domain specificity of integrative complexity. A large number of open‐ended responses from college students (Studies 2 and 3) and candidates in the 2004 Presidential election (Study 4) across an array of topic domains reveals little or no main effect of political ideology on integrative complexity, but rather topic domain by ideology interactions. Liberals are higher in complexity on some topics, but conservatives are higher on others. Overall, this large dataset calls into question the typical interpretation that conservatives are less complex than liberals in a domain‐general way.  相似文献

Using integrative complexity scoring, the current study addresses how communications by leaders of India and Pakistan have revealed their information processing and decision-making strategies. The hostility between India and Pakistan started with the official creation of the two states and has lasted through more than a half-century. It has been marked by four full-scale wars and almost constant ethnopolitical, terrorist, and guerrilla violence. It is one of the most enduring and bloody binational rivalries of recent decades. Shared aspects of history and culture make the comparisons relatively free of confounding factors. In common with previous findings, complexity scores have shown reliable associations with impending war and with continued peace (or low-intensity conflict).  相似文献

Indigenization in psychology leads to modes of theorizing based within local knowledge communities and defined in terms of culturally relevant criteria. The present study offers a conceptualization of the social psychology of science in terms of complexity theory. The value of alternative choices in advancing psychological knowledge is shown by a knowledge landscape whose shape depends on the diversity of paradigms within the community. Dominance by a single paradigm (such as a Western world view) leads to a single-peaked landscape where advances in knowledge are judged using only the criteria of that paradigm. Here, the most effective form of working is incremental step-by-step research; but this ignores the historical context of the indigenous community and runs the risk of promoting a kind of psychology that is irrelevant to its values and priorities. Indigenization is presented as a complexification of the knowledge community building on a diversity of world views, leading to a rugged, multiple-peaked knowledge landscape. Four features of working on rugged landscapes are examined: path dependence, showing the importance of history for shaping the direction of research; fostering research progress through seeding of multiple starting points; the benefits of locally dense networks within knowledge communities; and the role of policy-makers in tuning knowledge landscapes. Examples are drawn from the development of indigenous psychology within a number of countries.  相似文献

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information‐theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments.  相似文献
