Descending Marr's levels: Standard observers are no panacea

Carlos Zednik, Frank Jäkel

Research output: Contribution to journalArticleAcademicpeer-review


According to Marr, explanations of perceptual behavior should address multiple levels of analysis. Rahnev & Denison (R&D) are perhaps overly dismissive of optimality considerations at the computational level. Also, an exclusive reliance on standard observer models may cause neglect of many other plausible hypotheses at the algorithmic level. Therefore, as far as explanation goes, standard observer modeling is no panacea.
