A Navon figure is a type of visual stimulus used in psychological and neuroscientific research to study perception and attention. It is named after the psychologist David Navon, who first introduced this concept in 1977.

Description

Navon figures are composed of a large, global shape that is made up of smaller, local shapes. For example, a large letter "H" might be constructed out of many small letter "S"s. This type of figure is used to investigate how people process visual information, specifically whether they focus on the global shape or the local details.

Research Applications

Navon figures are used in studies of visual perception to understand how individuals prioritize different levels of visual information. Research has shown that people tend to process the global shape before the local details, a phenomenon known as the "global precedence effect."

Clinical Relevance

In clinical settings, Navon figures can be used to assess cognitive function in patients with neurological disorders. For example, individuals with autism spectrum disorder or schizophrenia may show different patterns of processing when viewing Navon figures compared to neurotypical individuals.
