Figure 1

Illustration of task manipulating the scale of visuospatial attention at the location to be remembered over 3 sec. Circular precues varying in size (1.6°, 5.2°, and 8.1°) preceded a black target dot (100 msec duration) with an SOA of 500 msec. There was a requirement to remember dot location over a 3-sec delay. After the delay, a decision was required indicating whether the location of a red test dot matched that of the target dot. (A) Match trial, with test location matching target location. (B) Nonmatch trial illustrated with test dot at one of three distances (1.9°, 3.8°, 5.7°) from target location.
