Human neural and behavioral activities have been reported to exhibit fractal dynamics known as 1/f noise, which is more aptly named 1/f scaling. Some argue that 1/f scaling is a general and pervasive property of the dynamical substrate from which cognitive functions are formed. Others argue that it is an idiosyncratic property of domain‐specific processes. An experiment was conducted to investigate whether 1/f scaling pervades the intrinsic fluctuations of a spoken word. Ten participants each repeated the word bucket over 1,000 (...) times, and fluctuations in acoustic measurements across repetitions generally followed the 1/f scaling relation, including numerous parallel yet distinct series of 1/f fluctuations. On the basis of work showing that 1/f scaling is a universal earmark of metastability, it is proposed that the observed pervasiveness of 1/f fluctuations in speech reflects the fact that cognitive functions are formed as metastable patterns of activity in brain, body, and environment.

The complex-systems approach to cognitive science seeks to move beyond the formalism of information exchange and to situate cognition within the broader formalism of energy flow. Changes in cognitive performance exhibit a fractal (i.e., power-law) relationship between size and time scale. These fractal fluctuations reflect the flow of energy at all scales governing cognition. Information transfer, as traditionally understood in the cognitive sciences, may be a subset of this multiscale energy flow. The cognitive system exhibits not just a single power-law (...) relationship between fluctuation size and time scale but actually exhibits many power-law relationships, whether over time or space. This change in fractal scaling, that is, multifractality, provides new insights into changes in energy flow through the cognitive system. We survey recent findings demonstrating the role of multifractality in (a) understanding atypical developmental outcomes, and (b) predicting cognitive change. We propose that multifractality provides insights into energy flows driving the emergence of cognitive structure. (shrink)

In this reproduction of his original publication of 1649, Rene Descartes discusses how seekers of knowledge can best attain true insight of the world around them. Often referred to as simply the Discourse on the Method, this work is frequently cited as one of the most important to appear during the Enlightenment era. It discusses the ideal means through which those in search of knowledge can approach the world, and the practice of science, as a means of attaining true and (...) definitive insight. The Discourse on Method is influential chiefly for its role in establishing the scientific method; a technique which scientists have used to make valid discoveries over the centuries. Descartes instructs the reader to doubt everything, and to use this universal doubt as a starting point from which to approach a problem. In addition to matters of science, Descartes reflects upon his own personal, religious beliefs. In addition to his Method, Descartes also explains certain social and personal notions such as obeying the laws and statutes of his country and prioritizing self-advancement over the achievement of material wealth or fortune. Famous for including the much-quoted phrase "Je pense, donc je suis" - "I think, therefore I am" - the Discourse on Method today stands as a crucial cornerstone of countless educational courses on philosophy.

The growth of esports as a recognized, organized, competitive activity in North America and Europe has evolved steadily from one of the most prominent sport industries in several Asian countries. Esports, which is still pursuing a widely accepted governance structure, has struggled to control the factors that typically act as a breeding ground for sport corruption. Within the esports industry, there is alleged widespread use of both prescription and off-label use of stimulants, such as modafinil, methylphenidate, and dextroamphetamine. Anti-doping policy (...) implementation in this environment may result in either the abuse of the Therapeutic Use Exemptions system or excluding too many competitors who have a legitimate need for these medications. In this paper, we contextualize esports and substance use within this emerging industry. Subsequently, we outline the specific challenges faced by esports organizations in crafting policies to address PEDs—one of the industry’s most pressing issues. Furt... (shrink)

The social and cognitive science replication crisis is partly due to the limitations of commonly used statistical tools. Inferential statistics require that unsystematic measurement variation is independent of system history, and weak relative to systematic or causal sources of variation. However, contemporary systems research underscores the dynamic, adaptive nature of social, cognitive, and behavioral systems. Variation in human activity includes the influences of intrinsic dynamics intertwined with changing contextual circumstances. Conventional inferential techniques presume milder forms of variability, such as unsystematic (...) measurement error, as in a Gaussian distribution. Inferential statistics indicate an elementary Newtonian cause-effect metaphor for change that is inconsistent with known principles of change in complex systems. Pattern formation in self-organizing systems and quantum probability are used to illustrate theoretical metaphors that instantiate alternative notions of change in complex systems. Inferential statistics and related techniques are crucial scientific resources. However, in the social and behavioral sciences, they must be practiced in conjunction with an appropriate general systems framework that accommodates intrinsic fluctuations and contextual adaptation.
