Psychology and neuroscience are concerned with the study of behavior, of internal cognitive
processes, and their neural foundations. However, most laboratory studies use constrained …

Traditional biomechanical analyses of human movement are generally derived from linear
mathematics. While these methods can be useful in many situations, they do not describe …

Most current decision-making research focuses on classical economic scenarios, where
choice offers are prespecified and where action dynamics play no role in the decision …

Derived from inverted pendulum dynamics, mediolateral Margin of Stability (MoS ML) is a
mechanically-grounded measure of instantaneous frontal-plane stability. However, average …

Many runners seek health professional advice regarding footwear recommendations to
reduce injury risk. Unfortunately, many clinicians, as well as runners, have ideas about how …

Variability is ubiquitous in human movement, arising from internal and external noise,
inherent biological redundancy, and from the neurophysiological control actions that help …

Older adults exhibit increased gait variability that is associated with fall history and predicts
future falls. It is not known to what extent this increased variability results from increased …

Walking humans display great versatility when achieving task goals, like avoiding obstacles
or walking alongside others, but the relevance of this to fall avoidance remains unknown …

A fundamental question in human motor neuroscience is to determine how the nervous
system generates goal-directed movements despite inherent physiological noise and …

In the last decade, the source and the functional meaning of motor variability have attracted
considerable attention in behavioral and brain sciences. This construct classically combined …
