Assessing visual search performance differences between Transportation Security Administration Officers and nonprofessional visual searchers
Some visual searches depend upon accuracy (e.g., radiology, airport security screening), and it is important for both theoretical and applied reasons to understand what factors best predict
Examining perceptual and conceptual set biases in multiple-target visual search
“big data” obtained from the mobile application Airport Scanner revealed that multiple-target search errors were substantially reduced when the two targets were identical, suggesting that the first-found target did indeed create biases during subsequent search.
The Ultra-Rare-Item Effect
By assessing search performance across millions of trials from the Airport Scanner smartphone application, it is demonstrated that the detection of ultra-rare items was disturbingly poor and had catastrophically low detection rates relative to targets with higher frequencies.
Competition between color salience and perceptual load during visual selection can be biased by top-down set
The present findings suggest that the competition between color salience and perceptual load can vary as a function oftask context, thereby supporting top-down accounts, although the precise aspect of task context remains to be identified.

The existing literature is reviewed to clarify the appropriate scenarios where subsequent search errors could be observed and several different measurement methods are used with several existing datasets to contrast and compare how each method would have affected the results and conclusions of those studies.
Visual salience can co-exist with dilution during visual selection.

The results of two experiments showed that the relative salience of the distractor influenced the magnitude of distractor interference under conditions of low perceptual load and dilution, suggesting that the effects of visual salience can coexist with theeffects of dilution (and load).
Improving the Efficacy of Security Screening Tasks: A Review of Visual Search Challenges and Ways to Mitigate Their Adverse Effects
This work reviews and discusses four specific challenges of the task itself that can negatively affect the accuracy of a security screening: target visibility, an unknown target set, the possible presence of multiple targets, and low target prevalence.
Cognitive Training for Military Application: a Review of the Literature and Practical Guide
In recent years, the potential to improve cognitive skills through training has captured the attention of academic researchers, the commercial market, and the general public. Numerous clinical and
Different Predictors of Multiple-Target Search Accuracy between Nonprofessional and Professional Visual Searchers
It is suggested that professional searchers may utilize different search strategies from those of nonprofessionals, and that search consistency, in particular, may provide a valuable tool for enhancing professional search accuracy.
Semantic and affective salience: the role of meaning and preference in attentional capture and disengagement.
The results suggested that increases in meaning can reduce attentional capture, and that while increased knowledge can reduce capture, affect can restore an item's ability to capture attention.
