Procedure. (A) Experiment 3. In each trial two stimuli were presented simultaneously; test at a peripheral location, and standard at the center. Observers were asked to report which stimulus had a higher spatial frequency. (B) Experiment 4. Each session started with the presentation of the standard stimulus and continued with the presentation of the test trials at a peripheral location (N, S, E, or W). Observers were asked to report which stimulus (the memorized standard or the test) had a higher spatial frequency. (This figure is not representative of the actual stimuli in terms of eccentricity and spatial frequency.) RT, response time.
