Depth of visual information processing

Depth of visual information processing.

The depth of visual information processing is identified with the longest randomly-generated binary-encoded spatial pattern whose partial repetitions can be detected. In contrast with the auditory detection of sequentially-presented constraints, the depth of perceptible visual encoding of spatially-presented constraints is sharply limited. Depths of about 35 were achieved for one-dimensional co...

evaluation of visual information processing speed in depressed people.

depression disorders are associated with serious dysfunction and depressive symptoms. cognitive slowing is a clear symptom observed in all depressed people. pvsat is a measure of cognitive function that specifically assesses visual information processing speed and flexibility, as well as calculation ability. the aim of the present study was to determine whether the paced visual serial addition ...

Evoked Potentials Studies of Visual Information Processing

Preattentive Processing of Numerical Visual Information

Humans can perceive and estimate approximate numerical information, even when accurate counting is impossible e.g., due to short presentation time. If the number of objects to be estimated is small, typically around 1-4 items, observers are able to give very fast and precise judgments with high confidence-an effect that is called subitizing. Due to its speed and effortless nature subitizing has...

Visual information processing: the structure and creation of visual representations.

For human vision to be explained by a computational theory, the first question is plain: What are the problems that the brain solves when we see? It is argued that vision is the construction of efficient symbolic descriptions from images of the world. An important aspect of vision is therefore the choice of representations for the different kinds of information in a visual scene. An overall fra...
