Five independent work packages will investigate fundamental predictions of summed error correction, especially that non-reinforced presentations of a cue are neither necessary nor sufficient to induce extinction. Instead, crucial factors should be type and strength of error signals triggered in the specific learning situation. Our aim is to understand how organisms integrate multiple signals to achieve a predictive model of their environment and how predictive values of multiple signals are modulated by experience in order to maintain a match between prediction and reality.
