What does the Navon experiment test?

Navon figures are used in tests of visual neglect. David Navon’s research demonstrated that global features are perceived more quickly than local features. Patients with simultanagnosia have difficulty identifying global features, and when presented with a Navon figure will identify only the local features.

What is global local task?

The local-global task measures the ability to focus attention on a specific feature of a stimulus – either global or local – while resisting distraction from other features (Navon, 1977). This is an important component of self-regulation, and could improve understanding of self-regulation and behavior.

How is Navon used in local and global processing?

Participants in local and global processing were shown three examples of a Navon letter on their screen while their task was explained depending on their encoding status. Global participants had to call out loud the large Navon letter while the Local participants had to name the small letters.

What do you need to know about the Navon figure?

Navon figure. Jump to navigation Jump to search. A Navon figure is made of a larger recognisable shape, such as a letter, composed of copies of a smaller different shape. Navon figures are used in tests of visual neglect. David Navon’s research demonstrated that global features are perceived more quickly than local features.

Which is an example of the Navon effect?

For example, a group of trees has local features (the individual trees) and the feature of a forest (the trees together). The basic finding of Navon’s work is that people are faster in identifying features at the global than at the local level. This effect is also known as global precedence. An example of a Navon figure is shown below.

Why are Navon figures used in visual neglect?

Navon figures are used in tests of visual neglect. David Navon’s research demonstrated that global features are perceived more quickly than local features. Jules Davidoff also performed research, but in a remote culture, finding opposite results; the participants more readily identified the local features.
