A15 – Understanding the prediction error driving extinction

Harald Lachnit, Metin Üngör (associated investigator)

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. 

Guiding questions of A15:

  • Is extinction modulated by the strength of negative prediction errors?
  • Do outcome omissions lead to acquisition when the outcome is under-expected?
  • Do outcome parings lead to extinction when the outcome is over-expected?
  • Is acquisition modulated by the strength of positive prediction errors?
  • Is extinction in multiple stimuli driven by the same error signal?
