Visual Search Task
Investigates attention by locating stimuli among distractors.
Spatial Attention
Assigns processing resources to relevant environmental stimuli.
Pop Out Phenomenon
Targets that stand out with little search time change.
Mean Response Time (RT)
Average time taken to respond in visual tasks.
Parallel Search
Simultaneous comparison of all display locations.
Serial Search
Sequentially focusing attention on each item.
Self-Terminating Serial Search
Stops searching upon finding the target.
Feature Integration Theory
Attention binds features into perceptual compounds.
Illusory Conjunctions
Miscombined features due to lack of attention.
Conjunction Targets
Targets defined by a combination of features.
Guided Search Theory
Two-stage search process for identifying targets.
Search Efficiency
Effectiveness of locating targets among distractors.
Automaticity
Fast, effortless processing without capacity requirements.
Stroop Effect
Demonstrates failure of focused attention with conflicting stimuli.
Controlled Processing
Deliberate, slow processing requiring attention.
Eriksen Flanker Task
Measures compatibility effects on attention.
Attentional Blink
Decline in detecting second target after first.
Rapid Serial Visual Presentation (RSVP)
Task presenting items quickly to study attention.
Visual Working Memory
Holds 4-5 items, enters serially at 50-60ms.
Candidate List
Initial targets identified in parallel search stage.
Display Size
Number of items presented in a visual search.
Slope Ratio
Indicates efficiency of search based on response time.
Feature Maps
Separate maps for different visual features.
Consistent Mapping
Distinct target and distractor sets in tasks.
Varied Mapping
Targets can also be distractors in some trials.
Cheetahs-in-the-Savannah
Analogy for visual search complexity control.
High-Level Properties
Complex characteristics influencing pop out effects.
