Prediction Accuracy and Average Response for Different Pattern Lengths in Both Tasks (Pattern, Random).

The prediction accuracy and average response for different pattern lengths in both tasks: Pattern, when the sequence was formed by a repeating pattern, and Random, when the sequence was shuffled randomly. In different simulations, the animats had 4 (figure panel A) or 8 (figure panel B) hidden nodes. The error bars are the standard errors for n = 12. PM  =  Expected average response for animats that do probability matching. Max  =  Expected average response for animats that perseverate. Random PM  =  Expected accuracy for animats that do probability matching in the random task. Random Max  =  Expected accuracy for animats that perseverate in the random task.
