Distractor rejection in visual search breaks down with more than a single distractor feature.
Previous research has established that interference from irrelevant-but-salient color distractors occurs when observers search for variable-shape singletons among uniform shapes (singleton detection), but not when they look for a specific shape among mixed shapes (feature search). In the current study, we replicated this finding, and additionally, we introduced a random variation of color. Inst...
متن کاملAge, target-distractor similarity, and visual search.
Younger and older adults were asked to find a single target in both feature- and conjunction- search conditions. Display size varied between 2 and 8 items, and target-distractor similarity ranged from relatively low to high levels. The accuracy data indicated that older adults had particular difficulty finding targets in high-similarity conjunction-search displays containing a large number of d...
متن کاملTarget-distractor discriminability in visual search.
Previous research has demonstrated that discriminability of target and background elements has powerful effects on visual search performance. Typically, discriminability has been manipulated between blocks or subjects, allowing subjects to anticipate the discriminability in advance of each trial, and the results, therefore, have been consistent with a wide range of models. Two experiments are r...
متن کاملTarget-to-distractor similarity can help visual search performance
We found an unexpected positive effect of target-to-distractor similarity (TD) in a visual search task, despite overwhelming evidence in the literature that TD similarity hurts visual search performance. Participants with no prior knowledge of Chinese performed 12 hour-long sessions over 4 weeks, where they had to find a briefly presented target character among a set of distractors. At the begi...
متن کاملReward Draws the Eye, Uncertainty Holds the Eye: Associative Learning Modulates Distractor Interference in Visual Search
Stimuli in our sensory environment differ with respect to their physical salience but moreover may acquire motivational salience by association with reward. If we repeatedly observed that reward is available in the context of a particular cue but absent in the context of another cue the former typically attracts more attention than the latter. However, we also may encounter cues uncorrelated wi...
