Comparing set summary statistics and outlier pop out in vision

Vision: Filling in and pop out

The 'pop out' of a distinctive element embedded in a regular pattern, and the 'filling in' of a blind spot, are dramatic manifestations of the way context affects visual perception. Recent studies shed light on the neurophysiological bases of these phenomena.

Summary statistics in vision

Cueing and pop-out

We describe experiments on the dynamics of pop-out from orientation. Target lines at an oblique orientation and orthogonal background elements were presented with various onset delays, and subjects' performance in target detection was measured. Detection rates increased for short delays compared to synchronous stimulus presentation, with a maximum at delta t = 30-60 ms. Control experiments show...

Do People “Pop Out”?

The human body is a highly familiar and socially very important object. Does this mean that the human body has a special status with respect to visual attention? In the current paper we tested whether people in natural scenes attract attention and "pop out" or, alternatively, are at least searched for more efficiently than targets of another category (machines). Observers in our study searched ...

False pop out.

A single, unique target often pops out quickly and efficiently from a field of homogenous distractors in visual search. Pop out has helped shape theories of visual attention and feature integration as well as to identify basic features in human vision. Here we report a new phenomenon, false pop out, wherein one of the homogenous distractors competes with the singleton target to pop out, perhaps...
