New concepts and computational models that integrate behavioral and neurophysiological
observations have addressed several of the most fundamental long-standing problems in …

The two contrasting theoretical approaches to visual perception, the constructivist and the
ecological, are briefly presented and illustrated through their analyses of space and size …

Todorov, Emanuel and Michael I. Jordan. Smoothness maximization along a predefined
path accurately predicts the speed profiles of complex arm movements. J. Neurophysiol. 80 …

The movements of the human arm have been extensively studied for a variety of goal-
directed experimental tasks. Analyses of the trajectory and velocity of the arm have led to …

Among the infinite number of possible movements that can be produced, humans are
commonly assumed to choose those that optimize criteria such as minimizing movement …

Monkeys traced spirals on a planar surface as unitary activity was recorded from either
premotor or primary motor cortex. Using the population vector algorithm, the hand's …

Behavioral and modeling studies have established that curved and drawing human hand
movements obey the 2/3 power law, which dictates a strong coupling between movement …

We propose a new camera-based biometric: visual signature identification. We discuss the
importance of the parameterization of the signatures in order to achieve good classification …

It is often claimed that point-light displays provide sufficient information to easily recognize
properties of the actor and action being performed. We examined this claim by obtaining …

To rekindle interest in investigating the cognitive and neuroscientific aspects of drawing, we
proposed to Cortex to set up a special issue covering the different theoretical and …
