Quizplus · Accepted Answer

The number of items in the visual display is the major independent variable of interest in studies of visual search. This variable influences the speed and accuracy of the search process, and is often manipulated to investigate how different factors (e.g. target-distractor similarity, spatial arrangement of items) affect visual search performance. RT and accuracy in making the present-absent judgment are dependent variables that are affected by the number of items in the display, but are not independent variables themselves. The size of the visual display can also be manipulated, but it is typically less important than the number of items for studying the basic mechanisms of visual search.
