Observers can look {visual search} for objects, features, locations, or times {target, search} in scenes or lists.
distractors
Other objects {distractor, search} are not targets. Search time is directly proportional to number of targets and distractors {set size, search}.
types
Searches {conjunction search} can be for feature conjunctions, such as both color and orientation. Conjunction searches {serial self-terminating search} can look at items in sequence until finding target. Speed decreases with number of targets and distractors.
Searches {feature search} can be for color, size, orientation, shadow, or motion. Feature searches are fastest, because mind searches objects in parallel.
Searches {spatial search} can be for feature conjunctions that have shapes or patterns, such as two features that cross. Mind performs spatial searches in parallel but can only search feature subsets {limited capacity parallel process}.
guided search theory
A parallel process {preattentive stage} suggests serial-search candidates {attentive stage} {guided search theory, search}.
