What can 1 billion trials tell us about visual search? (2015)
Journal Article

Mobile technology (e.g., smartphones and tablets) has provided psychologists with a wonderful opportunity: through careful design and implementation, mobile applications can be used to crowd source data collection. By garnering massive amounts of dat... Read More about What can 1 billion trials tell us about visual search?.

Perception and human information processing in visual search (2015)
Book Chapter

© Cambridge University Press 2015. Visual search is the process of finding specific target items within an environment using particular visual features or prior knowledge. Searches can be as easy as finding your friend with purple hair in a lecture h... Read More about Perception and human information processing in visual search.

Improvement in visual search with practice: Mapping learning-related changes in neurocognitive stages of processing (2015)
Journal Article

© 2015 the authors. Practice can improve performance on visual search tasks; the neural mechanisms underlying such improvements, however, are not clear. Response time typically shortens with practice, but which components of the stimulus–response pro...

Variation in visual search abilities and performance (2014)
Thesis

Visual search, the process of detecting relevant items within an environment, is a vital skill required for navigating one’s visual environment as well as for careers, such as radiology and airport security, that rely upon accurate searching. Researc... Read More about Variation in visual search abilities and performance.

I knew you were going to miss that: Predicting future visual search performance from initial search abilities (2013)
Presentation / Conference Contribution

A unique data source—hundreds of thousands of individuals who voluntarily played a smartphone game (Airport Scanner; Kedlin Company)—was used to assess predictors of visual search accuracy. Baseline performance was assessed on easy levels at the star... Read More about I knew you were going to miss that: Predicting future visual search performance from initial search abilities.

Face symmetry assessment abilities: Clinical implications for diagnosing asymmetry (2013)
Journal Article

Introduction An accurate assessment of face symmetry is necessary for the development of a dentofacial diagnosis in orthodontics, and an understanding of individual differences in perception of face symmetry between patients and providers is needed t...

Context matters: The structure of task goals affects accuracy in multiple-target visual search (2013)
Journal Article

Career visual searchers such as radiologists and airport security screeners strive to conduct accurate visual searches, but despite extensive training, errors still occur. A key difference between searches in radiology and airport security is the str... Read More about Context matters: The structure of task goals affects accuracy in multiple-target visual search.

Enhanced facial symmetry assessment in orthodontists (2013)
Journal Article

Assessing facial symmetry is an evolutionarily important process, which suggests that individual differences in this ability should exist. As existing data are inconclusive, the current study explored whether a group trained in facial symmetry assess... Read More about Enhanced facial symmetry assessment in orthodontists.

Assessing visual search performance differences between Transportation Security Administration Officers and nonprofessional visual searchers (2013)
Journal Article

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 performance. The current study administered a visual search...

Visual expertise: Insights gained by comparing professional populations (2013)
Presentation / Conference Contribution

Professionals whose careers depend on visual skills typically demonstrate superior performance on career-related tasks; farmers better determine the sex of day-old chicks (Biederman & Shiffrar, 1987), and bank tellers better detect counterfeit curren...

Characterizing clinical skill acquisition: Face symmetry assessment abilities in orthodontists (2013)
Presentation / Conference Contribution

Objectives: Assessing face symmetry is key to diagnosis in dentistry. By comparing performance on tests of visual cognition (symmetry assessment) across dental students, orthodontics residents, orthodontics faculty, and untrained controls, we explore...

Face symmetry assessment: Evidence for malleability and expertise (2012)
Presentation / Conference Contribution

Evaluating symmetry is an important element of face processing and contributes to judgments about attractiveness, healthiness, and mate selection. Although general face processing in healthy adult humans is well studied, less is known about whether s... Read More about Face symmetry assessment: Evidence for malleability and expertise.

In search of experience effects: How TSA officers differ from undergraduates on visual search tasks. (2012)
Presentation / Conference Contribution

Visual search is a routine activity that people perform countless times each day. Search is also crucial for certain professions (e.g., airport security, radiology), and here we examine how the extensive practice gained through these careers alters s...

Cognitive and neural plasticity due to visual search training (2012)
Presentation / Conference Contribution

Successful visual search is the endpoint of a cascade of cognitive processes including sensory analysis, attentional orienting, target discrimination, and response generation. These processes are governed by underlying neural mechanisms that can be... Read More about Cognitive and neural plasticity due to visual search training.

Visual search at the airport: Testing TSA officers (2012)
Presentation / Conference Contribution

A significant challenge for laboratory-based research is to adequately replicate conditions found in the real world. Likewise, a challenge for field-based research is to appropriately maintain the precision and control found within the laboratory. Th...

Neural correlates of learning during a visual search task (2012)
Presentation / Conference Contribution

Performance on visual search tasks can be improved with training; however, the neural mechanisms underlying such improvement are not clear. For example, although response times (RTs) typically shorten with training, it is unclear which components of... Read More about Neural correlates of learning during a visual search task.

Overcoming hurdles in translating visual search research between the lab and the field (2012)
Book Chapter

Research in visual search can be vital to improving performance in careers such as radiology and airport security screening. In these applied, or "field," searches, accuracy is critical, and misses are potentially fatal; however, despite the importan...

A Bayesian Optimal Foraging Model of Human Visual Search (2012)
Journal Article

Real-world visual searches often contain a variable and unknown number of targets. Such searches present difficult metacognitive challenges, as searchers must decide when to stop looking for additional targets, which results in high miss rates in mul...

Expertise in radiological screening and satisfaction of search (2011)
Presentation / Conference Contribution

Cognitive psychology studies of visual search typically use
novice searchers (often undergraduate students). Such studies have provided valuable insight into visual search performance, but how might expert searchers differ in their performance? Radi... Read More about Expertise in radiological screening and satisfaction of search.

Optimal models of human multiple-target visual search (2011)
Presentation / Conference Contribution

Unlike laboratory experiments, real-world visual search can contain multiple targets. Searching for an unknown number of targets creates a unique set of challenges for the observer, and often produces serious errors. We propose a Bayesian optimal for...
