WebAug 13, 2013 · Counterfactual learning signals (gray) correspond to fictive errors, operationalized as the difference between the best possible outcome and the actual outcome. c Functional data were restricted to a slab centered on the mesencephalon and tilted to cover the substantia nigra and ventral tegmental area Full size image 1. Webfictive reward information into behavior is compromised in addition. Chiu and colleagues found that fictive errors activate the caudate in smokers as well but that these signals do not influence subsequent choices [6], implicating impaired fictive learning in real-life problems like addiction and gambling (and playing the stock market as well).
