Konkle, Talia; Oliva, Aude – Journal of Experimental Psychology: Human Perception and Performance, 2012
When we recognize an object, do we automatically know how big it is in the world? We employed a Stroop-like paradigm, in which two familiar objects were presented at different visual sizes on the screen. Observers were faster to indicate which was bigger or smaller on the screen when the real-world size of the objects was congruent with the visual…

Arnold, Derek H.; Wegener, Signy V.; Brown, Francesca; Mattingley, Jason B. – Journal of Experimental Psychology: Human Perception and Performance, 2012
Grapheme-color synesthesia is an atypical condition in which individuals experience sensations of color when reading printed graphemes such as letters and digits. For some grapheme-color synesthetes, seeing a printed grapheme triggers a sensation of color, but "hearing" the name of a grapheme does not. This dissociation allowed us to…

Palmer, Evan M.; Horowitz, Todd S.; Torralba, Antonio; Wolfe, Jeremy M. – Journal of Experimental Psychology: Human Perception and Performance, 2011
Many visual search experiments measure response time (RT) as their primary dependent variable. Analyses typically focus on mean (or median) RT. However, given enough data, the RT distribution can be a rich source of information. For this paper, we collected about 500 trials per cell per observer for both target-present and target-absent displays…

Stroud, Michael J.; Menneer, Tamaryn; Cave, Kyle R.; Donnelly, Nick – Journal of Experimental Psychology: Human Perception and Performance, 2012
Eye movements were monitored to examine search efficiency and infer how color is mentally represented to guide search for multiple targets. Observers located a single color target very efficiently by fixating colors similar to the target. However, simultaneous search for 2 colors produced a dual-target cost. In addition, as the similarity between…

Andrews, Lucy S.; Watson, Derrick G.; Humphreys, Glyn W.; Braithwaite, Jason J. – Journal of Experimental Psychology: Human Perception and Performance, 2011
Evidence for inhibitory processes in visual search comes from studies using preview conditions, where responses to new targets are delayed if they carry a featural attribute belonging to the old distractor items that are currently being ignored--the negative carry-over effect (Braithwaite, Humphreys, & Hodsoll, 2003). We examined whether…

Chao, Hsuan-Fu – Journal of Experimental Psychology: Human Perception and Performance, 2011
The current study investigated attentional control through active inhibition of the identity of the distractor. Adapting a Stroop paradigm, the distractor word was presented in advance and made to disappear, followed by the presentation of a Stroop stimulus. Participants were instructed to inhibit the distractor in order to reduce its…

Anderson, Giles M.; Heinke, Dietmar; Humphreys, Glyn W. – Journal of Experimental Psychology: Human Perception and Performance, 2010
Four experiments examined the effects of precues on visual search for targets defined by a color-orientation conjunction. Experiment 1 showed that cueing the identity of targets enhanced the efficiency of search. Cueing effects were stronger with color than with orientation cues, but this advantage was additive across array size. Experiment 2…

Brockmole, James R.; Boot, Walter R. – Journal of Experimental Psychology: Human Perception and Performance, 2009
Distinctive aspects of a scene can capture attention even when they are irrelevant to one's goals. The authors address whether visually unique, unexpected, but task-irrelevant features also tend to hold attention. Observers searched through displays in which the color of each item was irrelevant. At the start of search, all objects changed color.…

Roelofs, Ardi – Journal of Experimental Psychology: Human Perception and Performance, 2011
Two experiments are reported in which the role of attribute exposure duration in naming performance was examined by tracking eye movements. Participants were presented with color-word Stroop stimuli and left- or right-pointing arrows on different sides of a computer screen. They named the color attribute and shifted their gaze to the arrow to…

Treccani, Barbara; Milanese, Nadia; Umilta, Carlo – Journal of Experimental Psychology: Human Perception and Performance, 2010
In 4 experiments, we intermixed trials in which the stimulus color was relevant with trials where participants had to judge the stimulus shape or parity and found that the logical-recoding rule (Hedge & Marsh, 1975) applied to the relevant dimension in a task can generalize to the irrelevant dimension of the other task. The mapping…

Leboe, Jason P.; Leboe, Launa C.; Milliken, Bruce – Journal of Experimental Psychology: Human Perception and Performance, 2010
According to a transfer-appropriate processing framework, immediate priming costs arise from a match between a prime and probe event on 1 dimension and a difference between those 2 events on some other dimension (i.e., a partial match). In Experiment 1, the authors used a Stroop priming procedure to generate 6 variants of partial match, yet only 1…

Williams, Carrick C.; Pollatsek, Alexander; Cave, Kyle R.; Stroud, Michael J. – Journal of Experimental Psychology: Human Perception and Performance, 2009
In 2 experiments, eye movements were examined during searches in which elements were grouped into four 9-item clusters. The target (a red or blue "T") was known in advance, and each cluster contained different numbers of target-color elements. Rather than color composition of a cluster invariantly guiding the order of search though…

Hirose, Nobuyuki; Osaka, Naoyuki – Journal of Experimental Psychology: Human Perception and Performance, 2010
A sparse mask that persists beyond the duration of a target can reduce its visibility, a phenomenon called "object substitution masking". Y. Jiang and M. M. Chun (2001a) found an asymmetric pattern of substitution masking such that a mask on the peripheral side of the target caused stronger substitution masking than on the central side.…

Makovski, Tal; Jiang, Yuhong V. – Journal of Experimental Psychology: Human Perception and Performance, 2009
When tracking moving objects in space humans usually attend to the objects' spatial locations and update this information over time. To what extent do surface features assist attentive tracking? In this study we asked participants to track identical or uniquely colored objects. Tracking was enhanced when objects were unique in color. The benefit…

Muller, Hermann J.; Geyer, Thomas; Zehetleitner, Michael; Krummenacher, Joseph – Journal of Experimental Psychology: Human Perception and Performance, 2009
Three experiments examined whether salient color singleton distractors automatically interfere with the detection singleton form targets in visual search (e.g., J. Theeuwes, 1992), or whether the degree of interference is top-down modulable. In Experiments 1 and 2, observers started with a pure block of trials, which contained either never a…
