Turing inspired a computer metaphor of the mind and brain that has been handy and has
spawned decades of empirical investigation, but he did much more and offered behavioral …

A rich and complex temporal structure of variability in postural sway characterizes healthy
and adaptable postural control. However, neurodegenerative disorders such as Parkinson's …

Biological and psychological processes routinely break ergodicity, meaning they fail to have
stable means (M ean) and independent variation over time that we might find in additive …

Dexterous postural control subtly complements movement variability with sensory
correlations at many scales. The expressive poise of gymnasts exemplifies this lyrical …

Biological and psychological processes have been conceptualized as emerging from
intricate multiplicative interactions among component processes across various spatial and …

Evidence of multifractal structures has spread to a wider set of physiological time series
supporting the intricate interplay of biological and psychological functioning. These …

Contemporary dynamical models of human postural control propose an intermittent
controller regulating the postural centre of pressure (CoP) about a stable saddle-shaped …

An adaptive response to unexpected perturbations requires near-term and long-term
adjustments over time. We used multifractal analysis to test how nonlinear interactions …

An enduring controversy in biological and psychological sciences has centered on the
tension between the role of random multiplicative cascade processes and the sometimes …

Quiet standing exhibits strongly intermittent variability that has inspired at least two
interpretations. First, variability can be intermittent through the alternating engagement and …
