The Complexity of Complexity

Human Development, 2009
The study dealt with the following questions about the nature and effects of complexity in children: Are responses to stimuli exemplifying any of the complexity dimensions (heterogeneity of elements, irregularity of arrangement, amount of material, irregularity of shape, incongruities) interrelated? Are these dimensions interrelated ?

On the complexity of communication complexity

Proceedings of the forty-first annual ACM symposium on Theory of computing, 2009
We consider the following question: given a two-argument boolean function f, represented as an N x N binary matrix, how hard is it to determine the (deterministic) communication complexity of f?We address two aspects of this question. On the computational side, we prove that, under appropriate cryptographic assumptions (such as the intractability of ...

Complexities of complex contrast

SPIE Proceedings, 2012
For the visual system, luminance contrast is a fundamental property of images, and is one of the main inputs of any simulation of visual processing. Many models intended to evaluate visual properties such as image discriminability compute perceived contrast by using contrast sensitivity functions derived from studies of human spatial vision.
