Visual search can be aided by a search template: a preparatory representation of relevant target features. But which features are relevant in complex, real-world category search? Previous research suggests that this template must be flexible to account for variations in naturalistic stimulus properties such as size and occlusion, and that shapes of diagnostic parts of objects are a likely candidate. Here, in three experiments, we systematically evaluated the contribution of diagnostic object parts and whole object shape to the category-level search template. Our hypothesis was that features that better match the active search template will capture attention during search more strongly than partially-matching features. Results showed that while whole objects captured attention reliably and globally across the visual field, diagnostic parts failed to do so in all three experiments. This suggests that whole object shape is a necessary component of the category-level search template.

All models of attention include the concept of an attentional template (or a target or search template). The template is conceptualized as target information held in memory that is used for prioritizi...
Humans are able to achieve visual object recognition rapidly and effortlessly. Object categorization is commonly believed to be achieved by interaction between bottom-up and top-down cognitive process...
In real-world environments, information is typically multisensory, and objects are a primary unit of information processing. Object recognition and action necessitate attentional selection of task-rel...

Many aspects of our everyday behaviour require that we search for objects. However, in real situations search is often conducted while internal and external factors compete for our attention resources...

A highly customized interactive medium or program that allows individuals to learn and practice real world activities in an accurate, realistic, safe and secure environment.
A genus of snakes of the family VIPERIDAE. About 30 species are currently recognized, found in southeast Asia and adjacent island chains. The Okinawa habu frequently enters dwellings in search of rats and mice; the Chinese habu is often found in suburban and agricultural areas. They are quite irritable. (Moore: Poisonous Snakes of the World, 1980, p136)
A system using beamed and reflected radio signals to and from an object in such a way that range, bearing, and other characteristics of the object may be determined.
The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION.
The act of "taking account" of an object or state of affairs. It does not imply assessment of nor attention to the qualities or nature of the object.
