Contrasting effects of sensory limits and capacity limits in visual selective attention.
The effects of perceptual load and those of target-stimulus degradation on distractor processing were contrasted. Targets either had to be found among several nontargets (high perceptual load) or were presented alone and were intact (low perceptual load), had reduced size and contrast (Experiment 1), had reduced duration and were followed by a mask (Experiment 2), or had reduced visual acuity o...
متن کاملProcessing Capacity Limits Are Not Explained by Storage Limits
Cowan’s review shows that a short-term memory limit of four items is consistent with a wide range of phenomena in the field. However he does not explain that limit, whereas an existing theory does offer an explanation for capacity limitations. Furthermore processing capacity limits cannot be reduced to storage limits as Cowan claims. In his excellent review, Cowan concludes that short term memo...
متن کاملDiscrete capacity limits in visual working memory.
The amount of information we can actively maintain 'in mind' is very limited. This capacity limitation, known as working memory (WM) capacity, has been of great interest because of its wide scope influence on the variety of intellectual abilities. Recently, there has been an ongoing debate about how this capacity should be best characterized. One viewpoint argues that WM capacity is allocated i...
متن کاملPerceptual capacity limits in visual detection and search
The present research tests limitedand unlimited-capacity theories of perception by comparing accuracy in detection and search tasks under conditions of simultaneous and successive presentation of array items. The unlimited-capacity approach predicts no difference between simultaneous and successive presentation when nonperceptual factors are controlled. The limitedcapacity approach predicts an ...
متن کاملThe Scope and Limits of Top-Down Attention in Unconscious Visual Processing
Attentional selection plays a critical role in conscious perception. When attention is diverted, even salient stimuli fail to reach visual awareness. Attention can be voluntarily directed to a spatial location or a visual feature for facilitating the processing of information relevant to current goals. In everyday situations, attention and awareness are tightly coupled. This has led some to sug...
