Visual search is modulated by action intentions.
The influence of action intentions on visual selection processes was investigated in a visual search paradigm. A predefined target object with a certain orientation and color was presented among distractors, and subjects had to either look and point at the target or look at and grasp the target. Target selection processes prior to the first saccadic eye movement were modulated by the different ...
متن کاملSemantic category effects in visual word search
The initial question was whether subjects could categorize a word semantically before they precisely identified the word itself. This failed to occur. When searching a visual display for a single target word, subjects searched at the same rate whether the distractors were in the same or in a different semantic category. However, when the size of the target set was increased to three, then six, ...
متن کاملPreparatory patterns of neural activity predict visual category search speed
Rapidly detecting target object categories when objects are embedded in naturalistic scenes is facilitated by preparatory baseline signal changes. However, it is unclear as to what information most strongly predicts perceptual speed in terms of the minimal exposure duration required for accurate detection. Using novel surface-based spatiotemporal pattern classification, we found that while cate...
متن کاملCategory Search for Video Using Semantic Visual Templates
We tackle the problem of category search for video using Semantic Visual Templates (SVTs). SVTs represent personalized views of a concept and define an effective set of queries to retrieve a general category of images and videos. The system generates SVTs in two stages: training initial templates and Bayesian relevance feedback. Given a labeled database of videos, the system trains an initial s...
متن کاملSelection-for-action in visual search.
Grasping an object rather than pointing to it enhances processing of its orientation but not its color. Apparently, visual discrimination is selectively enhanced for a behaviorally relevant feature. In two experiments we investigated the limitations and targets of this bias. Specifically, in Experiment 1 we were interested to find out whether the effect is capacity demanding, therefore we manip...
