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.

Contextual Cueing

Visual search in which some distractor configurations repeat across blocks; faster search on repeated configurations indexes implicit spatial context learning. Engages 4 processes.

Multiple Object Tracking

Participants track a subset of identical moving objects among distractors for several seconds; tracking accuracy indexes sustained multifocal attention. Engages 5 processes.

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. Engages 5 processes.

Marked for review

The filing of these tasks is a judgement call; the note says why they are here and where else they could go.

Contextual Cueing

Visual search with repeated layouts; the learning could argue for conditioning and implicit learning
