Q1. What are the contributions in this paper?
S from the above 779 articles were reviewed. An intermediate shortlist of 109 articles of interest was then constructed, which were studied in detail. Inclusion criteria were as follows: ( 1 ) primary research studies using human adult participants ; ( 2 ) prediction error calculated using Rescorla Wagner or TD models, or from models derived from either of these ; ( 3 ) coordinates of prediction error provided in Montreal Neurological Institute ( MNI ) or Talairach standard stereotactic space ; ( 4 ) the study involved use of an experimental reinforcement learning task providing subject feedback ( n. b. studies were excluded where tasks involved the simple probabilistic allocation of reward or punishment such as monetary incentive delay tasks ).
