Informativeness of visual features guides search
While visual search is known to be heavily guided by visual features similar to those in the search target, little is known about how we select the feature dimensions – such as luminance or orientation to guide search so efficiently. Here we introduce a novel measure of the informativeness of individual feature dimensions for a given search task. By analyzing human eye movements during search i...
متن کاملRace Guides Attention in Visual Search.
It is known that faces are rapidly and even unconsciously categorized into social groups (black vs. white, male vs. female). Here, I test whether preferences for specific social groups guide attention, using a visual search paradigm. In Experiment 1 participants searched displays of neutral faces for an angry or frightened target face. Black target faces were detected more efficiently than whit...
متن کاملHaptic Shape Processing in Visual Cortex
Humans typically rely upon vision to identify object shape, but we can also recognize shape via touch (haptics). Our haptic shape recognition ability raises an intriguing question: To what extent do visual cortical shape recognition mechanisms support haptic object recognition? We addressed this question using a haptic fMRI repetition design, which allowed us to identify neuronal populations se...
متن کاملHow Chromaticity Guides Visual Search in Real-World Scenes
To study visual attention during search processes, numerous studies measured the selectivity of observers’ saccadic eye movements for local display features. These experiments almost entirely relied on simple, artificial displays with discrete search items and features. Recently, a first study on saccadic selectivity in real-world scenes was conducted, demonstrating visual guidance by low-level...
متن کاملScene context guides eye movements during visual search
How does scene context guide search behavior to likely target locations? We had observers search for scene-constrained and scene-unconstrained targets, and found that scene-constrained targets were detected faster and with fewer eye movements. Observers also directed more initial saccades to target-consistent scene regions and devoted more time to searching these regions. However, final checkin...
