Visual search and tracking tasks

A target must be found among, or followed through, a field of distractors; search slopes, detection accuracy or tracking capacity are the measures.

This family contains 4 tasks and cross-lists 1 more.

Contextual Cueing

Visual search in which some distractor configurations repeat across blocks; faster search on repeated configurations indexes implicit spatial context learning.

Multiple Object Tracking

Participants track a subset of identical moving objects among distractors for several seconds; tracking accuracy indexes sustained multifocal attention.

Useful Field of View

Brief central identification combined with peripheral localization under increasing distractor and divided-attention load; thresholds index processing speed and divided attention.

Visual Search

Detection of a target in a display of distractors; search slopes across set size dissociate feature (parallel) from conjunction (serial) search.

Marked for review

A review mark means the assignment is a judgement call the curator has flagged for a second opinion. On the family an entry is filed under it means “not sure this is the right home”; on a cross-listing it means “not sure this belongs here at all”. The note names the alternative or the doubt. Comments go to the issue tracker.
