Facilitation of color discrimination by verbal and visual cues

Fundamental differences in visual search with verbal and pictorial cues

Three experiments examined the effects of using informative verbal and pictorial cues on participants' abilities to perform visual search. By providing participants with more time to encode the cues than had been used previously, all three experiments revealed long-lasting pictorially cued search advantages that stabilized over time. Experiments 1 and 3 demonstrated that searching for changing ...

Color discrimination in Caspian pony

Combination of texture and color cues in visual segmentation

The visual system can use various cues to segment the visual scene into figure and background. We studied how human observers combine two of these cues, texture and color, in visual segmentation. In our task, the observers identified the orientation of an edge that was defined by a texture difference, a color difference, or both (cue combination). In a fourth condition, both texture and color i...

Regional cues and visual discrimination in the rabbit.

Rabbits were trained to discriminate patterns consisting of straight bars and rows of dots of different orientation. It was found that using proximal pattern presentation, at a distance of 5 cm in front of the animal, dot rows of different orientation are not discriminated on the basis of tilt extrapolation, but by the use of regional cues.

No evidence for overshadowing or facilitation of spatial pattern learning by visual cues.

Two experiments were conducted to examine the effects of redundant and relevant visual cues on spatial pattern learning. Rats searched for hidden food items on the tops of poles that formed a square (Experiment 1) or a checkerboard (Experiment 2) pattern. The experimental groups were trained with visual cues that specified the locations of the baited poles. All groups were tested without visual...
