However, the potential applications and relevance of this approach are contingent on several (often implicit) assumptions, including that computational parameters 1) are recoverable, 2) are reliable over time, 3) reflect conceptually similar processes across different tasks, and 4) relate to symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291726105340_sec2\" sec-type=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      To illustrate and test these assumptions for a selection of commonly used cognitive tasks, we recruited a large online sample of participants (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a0548), who completed seven mental health questionnaires and five tasks.

Finally, only parameters from two of the five tasks (four-armed bandit and cognitive effort) related to symptoms, and these relationships were weak.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291726105340_sec4\" sec-type=\"conclusions\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>It seems that at least some of the implicit assumptions made when advocating for the use of computational models in psychiatry are not met for these popular tasks and computational models.
