Experimental data (left) and simulated results (right) of a human predictive learning experiment by Dibbets, Maen and Bossen (2000), which studied the blocking effect with stimuli whose spatial position either remained fixed or varied across training trials. The experiment found a reliable blocking effect with spatially fixed stimuli, but not with randomly positioned stimuli. The simulation reproduced these results.
