We propose in this paper a reassessment of the original data Hausdorff et al. (Hausdorff JM, Purdon PL, Peng C-K, Ladin Z, Wei JY, Goldberger AR. J Appl Physiol 80: 1448-1457, 1996). confirm, using autoregressive fractionally integrated moving average modeling, presence genuine fractal correlations stride interval series self-paced conditions. In contrast with conclusions authors, we show that did not disappear metronomic The intervals presented antipersistent correlations, and 1/f...
The displacement of the center-of-pressure (COP) during quiet stance has often been accounted for by control COP position dynamics. In this paper, we discuss conclusions drawn from previous analyses dynamics using fractal-related methods. On basis some methodological clarification and analysis experimental data stabilogram diffusion analysis, detrended fluctuation an improved version spectral show that velocity is typically bounded between upper lower limits. We argue hypothesis intermittent...
A number of recent research works tried to apply fractal methods psychological or behavioral variables. Quite often, nevertheless, the use analyses remains rudimentary, and goal researchers seems limited evidencing presence long- range correlation in data sets. This article presents some developments monofractals theory, related methodological refinements. We also discuss a specific issues application research. Finally, we consider potential such approach for renewal classical psychology science.
We evaluate the performance of autoregressive, fractionally integrated, moving average (ARFIMA) modelling for detecting long-range dependence and estimating fractal exponents. More specifically, we test procedure proposed by Wagenmakers, Farrell, Ratcliff, compare results obtained with Akaike information criterion (AIC) Bayes (BIC). The present studies show that ARFIMA is able to adequately detect in simulated series. Conversely, this method tends produce a non-negligible rate false...
The complexity matching effect refers to a maximization of information exchange, when interacting systems share similar complexities. A working conjecture states that tend match their complexities in order enhance synchronization. This has been observed number synchronization experiments, and interpreted as transfer multifractality between systems. Finally, it shown two different levels interact, this operates from the most complex system less complex, yielding an increase latter....
Introduction: The hypothesis of the loss complexity with aging and disease has received strong attention. Especially, decrease stride interval series in older people, during walking, was shown to correlate falling propensity. However, recent experiments showed that a restoration walking people could occur through prolonged experience synchronized younger companion. This result interpreted as consequence matching effect. Experiment: aim present study analyze link between clinical measures...
The aim of the present study was to examine effects an exercise moderate intensity (60% maximal aerobic power) on specific information-processing mechanisms. 22 students completed 3 10-min. bouts a bicycle ergometer. Concomitantly, participants performed six manual-choice-reaction tasks manipulating task variables (Signal Intensity, Stimulus-Response Compatibility, and Time Uncertainty) two levels. Reaction tests, randomly ordered, were administered at rest during exercise. A significant...
Based on the dynamical systems perspective, present study aimed to explore how states of involvement toward mastery, performance-approach, and performance-avoidance goals (Elliot & Church, 1997) flow, are interrelated, activated during a practice judo combat. Using retrospective video recall method, two male national level competitors expressed computer their moment-to-moment each goal. Self-confrontation interviews also based were immediately conducted. Analyses variance revealed...
We analyzed serial dependencies in periods and asynchronies collected during oscillations performed synchrony with a metronome. Results showed that contain 1/f fluctuations, the series of antipersistent dependence. The analysis phase portrait revealed specific asymmetry induced by synchronization. propose hybrid limit cycle model including cycle-dependent stiffness parameter provided fractal properties, parametric driving function based on velocity. This accounts for most experimentally...
The fractional Gaussian noise/fractional Brownian motion framework (fGn/fBm) has been widely used for modeling and interpreting physiological behavioral data. concept of 1/ f noise, reflecting a kind optimal complexity in the underlying systems, is central interest this approach. It generally considered that fGn fBm represent continuum, punctuated by boundary “ideal” noise. In present paper, we focus on correlation properties discrete-time versions these processes (dfGn dfBm). We especially...
