A Theory of Visual Attention
A unified theory of visual recognition and attentional selection is developed by integrating the biased-choice model for single-stimulus recognition (Luce, 1963; Shepard, 1957) with a choice model for selection from multielement displays (Bundesen, Pedersen, & Larsen, 1984) in a race model framework. Mathematically, the theory is tractable, and it specifies the computations necessary for select...
متن کاملA Boolean map theory of visual attention.
UNLABELLED A theory is presented that attempts to answer two questions. What visual contents can an observer consciously access at one moment? ANSWER only one feature value (e.g., green) per dimension, but those feature values can be associated (as a group) with multiple spatially precise locations (comprising a single labeled Boolean map). How can an observer voluntarily select what to acces...
متن کاملVisual Attention Using Game Theory
The question “what is on the table?” is normally simple for a human, but difficult for a machine. The problem is that the machine does not know what to search for, as no visual properties of the targets are known. Machine-vision algorithms, in general, need explicit knowledge of visual properties to perform object detection. Moreover, several visual properties must be considered to provide robu...
متن کاملTesting Visual Attention in Dynamic Environments
We investigate attention as the active pursuit of useful information. This contrasts with attention as a mechanism for the attenuation of irrelevant information. We also consider the role of short-term memory, whose use is critical to any model incapable of simultaneously perceiving all information on which its output depends. We present several simple synthetic tasks, which become considerably...
متن کاملAttention Processing in Depressed Mood: Testing Defocused Attention Hypothesis
Depressed mood effects attention and its span. The present study aimed to compare the allocation of attention to relevant and irrelevant neutral stimuli in depressed and non-depressed participants. The studied populations include all the students from Azad university of Ahwaz and the undergraduate psychology students from Shahid Bahonar University of Kerman. After completion of Beck Depression ...
