“…The dominance times are irregular and rather unpredictable, so that they need to be described by their statistical properties. Since the classic work of Borsellino et al (1972) on gamma distribution of experimental perceptual dominance time series researchers have generally compared their experimental data or theoretical model results with gamma distributions, e.g., experiments by Go´mez et al (1995), Miller (1998), andVetter et al (2000) and models by Ditzinger and Haken (1990), Haken (1994), Nagao et al (2000), Otterpohl et al (2000), Wilson et al (2000), and Laing and Chow (2002). The gamma distribution is related to Poisson processes in which the numbers of changes in nonoverlapping intervals are independent for all intervals.…”

Perceptual multistability, alternative perceptions of an unchanging stimulus, gives important clues to neural dynamics. The present study examined 56 perceptual dominance time series for a Necker cube stimulus, for ambiguous motion, and for binocular rivalry. We made histograms of the perceptual dominance times, based on from 307 to 2478 responses per time series (median=612), and compared these histograms to gamma, lognormal and Weibull fitted distributions using the Kolmogorov-Smirnov goodness-of-fit test. In 40 of the 56 tested cases a lognormal distribution provided an acceptable fit to the histogram (in 24 cases it was the only fit). In 16 cases a gamma distribution, and in 11 cases a Weibull distribution, were acceptable but never as the only fit in either case. Any of the three distributions were acceptable in three cases and none provided acceptable fits in 12 cases. Considering only the 16 cases in which a lognormal distribution was rejected ( p<0.05) revealed that minor adjustments to the fourth-moment term of the lognormal characteristic function restored good fits. These findings suggest that random fractal theory might provide insight into the underlying mechanisms of multistable perceptions.

Selforganization is a process by which the interaction between the parts of a complex system gives rise to the spontaneous emergence of patterns, structures or functions. In this interaction the system elements exchange matter, energy and information. We focus our attention on the relations between selforganization and information in general and the way they are linked to cognitive processes in particular. We do so from the analytical and mathematical perspective of the "second foundation of synergetics" and its "synergetic computer" and with reference to several forms of information: Shannon's information that deals with the quantity of a message irrespective of its meaning, semantic and pragmatic forms of information that deal with the meaning conveyed by messages and information adaptation that refers to the interplay between Shannon's information and semantic or pragmatic information. We first elucidate the relations between selforganization and information theoretically and mathematically and then by means of specific case studies.

“…(1) applies to a system then the system may be described by means of extended synergetics. Extended synergetic models have been studied to describe selective attention and scene decomposition [6,7], the oscillatory perception of ambivalent figures [8,9] and the counterpart on the acoustic level, the so-called verbal transformation effect [10,11]. Moreover, the extended synergetic approach has been used to address transitions between perceptual-cognitive-behavioral patterns in the case of transitions that exhibit negative hysteresis [12,13].…”

A nonlinear physics model based on extended synergetics for the flow of infant actions during infant-mother face-to-face communications

The temporal ordering or flow of infant actions in the context of infant-mother face-to-face communication is discussed from a nonlinear physics perspective. The actions are considered as spatio-temporal patterns that emerge due to self-organization. The presence of a particular action is described in terms of a finite amplitude of the respective pattern. In line with benchmark models from synergetics and population dynamics, nonlinear amplitude equations that determine the evolution of the infant actions are defined. The model is extended to take selfinhibition and forgetting into account. More precisely, it is shown that the flow of infant actions during infant-mother communication can be explained by assuming that the infant behavior inhibits itself such that after a certain period of time the performed behavior becomes unstable and a transition towards a new behavior occurs. The proposed model is applied to literature data about three minute periods of infant-mother face-to-face communication. Since the model parameters determine the characteristic properties of the flow of infant actions, the conclusion is drawn that changes of the flow characteristics observed on the behavioral level during infant development correspond to changes of parameters on the neurobiological level that happen on the relative slow time scale of infant maturation.
