There is a revised version at: https://osf.io/4nx2vPrevious work (Glautier, 2013) showed that the responses made by humans on trial n insimple associative learning tasks were influenced by events that took place on trial n−1and a simple extension of the Rescorla-Wagner Model (RWM Rescorla & Wagner,1972), the Memory Environment Cue Array (MECA) model, was presented to accountfor those results. In the current work further evidence of non-local influences onresponding during associative learning

In two experiments the Akaikeweight analyses strongly supported the simpler Rescorla-Wagner model over the MECAmodel but the qualitive and näive maximum likelihood analyses strongly supported theMECA model model over the simpler Rescorla-Wagner model. In Experiment 2 thisapparent conflict was resolved using a generalisation criterion test (Ahn, Busemeyer,Wagenmakers, & Stout, 2008; Busemeyer & Wang, 2000) which gave clear support tothe MECA model over the Rescorla-Wagner model. These results demonstrate thesuperiority of model selection using predictive validity, where possible, over selectionusing statistical adjustments for model complexity.
