Rapid size scaling in visual search
In order to compute a representation of an object's size within a 3D scene, the visual system must scale retinal size by an estimate of the distance to the object. Evidence from size discrimination and visual search studies suggests that we have no access to the representation of retinal size when performing such tasks. In this study we investigate whether observers have early access to retinal...
متن کاملSimilarity relations in visual search predict rapid visual categorization.
How do we perform rapid visual categorization?It is widely thought that categorization involves evaluating the similarity of an object to other category items, but the underlying features and similarity relations remain unknown. Here, we hypothesized that categorization performance is based on perceived similarity relations between items within and outside the category. To this end, we measured...
متن کاملSize-based selection in rapid serial visual presentation
Several recent studies [Farell, B., & Pelli, D. (1993). Can we attend to large and small at the same time? Vision Research, 33, 2757-72; Shih, S., & Sperling, G. (1996). Is there feature-based attentional selection in visual search? Journal of Experimental Psychology: Human Perception and Performance, 22, 758-79] have found that visual selection based on the size of stimuli is impossible when t...
متن کاملEffects of set-size and lateral masking in visual search.
In the present research, the roles of lateral masking and central processing limitations in visual search were studied. Two search conditions were used: (1) target differed from distractors by presence/absence of a simple feature; (2) target differed by relative position of the same components only. The number of displayed stimuli (set-size) and the distance between neighbouring stimuli were va...
متن کاملSize Matters: Large Objects Capture Attention in Visual Search
Can objects or events ever capture one's attention in a purely stimulus-driven manner? A recent review of the literature set out the criteria required to find stimulus-driven attentional capture independent of goal-directed influences, and concluded that no published study has satisfied that criteria. Here visual search experiments assessed whether an irrelevantly large object can capture atten...
