Natural image coding in V1: how much use is orientation selectivity?

Apr 2009 Orientation selectivity is the most striking feature of simple cell coding in V1 that has been shown to emerge from the reduction of higher-order correlations in natural images in a large variety of statistical image models. The most parsimonious ... Read more...

Encouraging the perceptual underdog: positive affective priming of nonpreferred local-global processes.

30 Mar 2009 Two experiments examined affective priming of global and local perception. Participants attempted to detect a target that might be present as either a global or a local shape. Verbal primes were used in 1 experiment, and pictorial primes were used ... Read more...

Operation compatibility: a neglected contribution to dual-task costs.

30 Mar 2009 Traditionally, dual-task interference has been attributed to the consequences of task load exceeding capacity limitations. However, the current study demonstrates that in addition to task load, the mutual compatibility of the concurrent processes ... Read more...
