Early oculomotor capture by new onsets driven by the contents of working memory.

abstract：:It is commonly believed that objects viewed in certain contexts may be more or less salient. Measurements of salience have usually relied on asking observers "How much does this object stand out against the background?". In this study, we measured the salience of objects by assessing the distraction they produce for s...

abstract：:Edge detection is widely believed to be an important early stage in human visual processing. However, there have been relatively few attempts to map human edge detection filters. In this study, observers had to locate a randomly placed step edge in brown noise (the integral of white noise) with a 1/f2 power spectrum. ...

A consequence of seeing the world from a single point in space is that the outlines of occluding and occluded surfaces have the same shape.
