Can someone help with a brief comparison of one early theory of attention to the guided search theory of attention? Also, please help with describing how these theories can apply to visual search. What is an example of one cultural and one social variable that might influence attention?
I think I can help you with this one as well:
Let's subdivide this as simply as we can (this stuff can get really abstract) --
In terms of basic visual, guided search:
Features (or singularity) -
This approach to searching theory stresses a single ingredient that makes the target a unique thing (in a crowd of other, 'distracting' things). This is the simplest approach, since there is only one thing for which we are looking (this matters for the Posner theory below).
Conjunction or connectedness -
This is more complex, since the target is more complex, and contains many things that make it stand out from the 'distractors.' We here are looking for a broader 'idea' rather than a simple object. In a sense, it is a 'universal' because it is an object that, in fact, contains many other objects within it. These other objects have something in common (i.e. they are not contradictory, they support each other, like a lemon is oval and yellow - the two go together in that object).
(The basic idea)
This approach stresses 'preattentive' concepts - that is, what we ...
Theories of attention and the guided search theory is examined. How these theories can apply to visual search is determined.
