| Visual Distractor/Visual Attention | task | This category is a catch-all for visuoattention paradigms. Examples include: subjects press a button when a visual target (letters, bars, circles, asterisks, LEDs, etc) appears; subjects detect changes in luminance, shape, or color of visual stimuli; subjects fixate on a central stimuli while ignoring peripheral distractors... |
| visual imagery | concept | or mental image, is an experience that, on most occasions, significantly resembles the experience of perceiving some object, event, or scene, but occurs when the relevant object, event, or scene is not actually present to the senses... |
| visual masking | concept | the reduction or elimination of the visibility of a brief (≤ 50 ms) stimulus, called the “target”, by the presentation of a second brief stimulus, called the “mask”. |
