Effects of Noisy Distractors and Stimulus Redundancy on Visual Search
نویسندگان
چکیده
In a visual search task, subjects detected the presence of a target (long vertical line) among distractors that differed in length, orientation, or both. Distractors were designed to model the random variability found in naturalistic data by having them vary normally around the mean distractor. As predicted, adding variability to distractors eliminated popout by increasing reaction times and search function slopes, but redundant coding on two dimensions reduced search times and restored the popout effect.

Visual search for a target changing in synchrony with an auditory signal.
We examined whether the detection of audio-visual temporal synchrony is determined by a pre-attentive parallel process, or by an attentive serial process using a visual search paradigm. We found that detection of a visual target that changed in synchrony with an auditory stimulus was gradually impaired as the number of unsynchronized visual distractors increased (experiment 1), whereas synchron...
متن کاملA signal detection model predicts the effects of set size on visual search accuracy for feature, conjunction, triple conjunction, and disjunction displays.
Recently, quantitative models based on signal detection theory have been successfully applied to the prediction of human accuracy in visual search for a target that differs from distractors along a single attribute (feature search). The present paper extends these models for visual search accuracy to multidimensional search displays in which the target differs from the distractors along more th...
متن کاملDetection of multidimensional targets in visual search
Search performance for targets defined along multiple dimensions was investigated with an accuracy visual search task. Initially, threshold was measured for targets that differed from homogeneous distractors along a single dimension (e.g., a reddish target among achromatic distractors, or a right-tilted target among vertically oriented distractors). Threshold was then measured for a multidimens...
متن کاملCan intertrial priming account for the similarity effect in visual search?
In a visual search task, a salient distractor often elongates response times (RTs) even when it is task-irrelevant. These distraction costs are larger when the irrelevant distractor is similar than when dissimilar to the target. In the present study, we tested whether this similarity effect is mostly due to more frequent oculomotor capture by target-similar versus target-dissimilar distractors ...
متن کاملVisual Perception of Structured Symbols
A set of psychological experiments was conducted to explore the effects of stimulus structure on visual search processes. Results of the experiments, in which subjects searched for target stimuli among numerous other stimuli that served as distractors in stimulus displays, provide clear indications of interactive effects on visual search time of stimulus structure and the structure of the viewi...
