Who doesn't like a good model of the brain? Yet, from simple regression to neural nets, some limitations keep popping up (e.g., overfitting) @mjwolff.bsky.social & I saw some cool but puzzling data, ran a quick analysis & found one such limitation: model mimicry. Now in #naturecommunications &π§΅below

If you work with perceptual confidence judgments, you may be interested in our CNCB model of confidence ratings. Joint work with Vincent de Gardelle.

turns out, u can analyze meta-d' w/ just reaction times rather than confidence. loses some info & also a bit different. but maybe RT really isn't so metacognitive, so we might have to call it pseudo-meta-d'

Visual experience orthogonalizes visual cortical responses
Training in a visual task changes V1 tuning curves in odd ways. This effect is explained by a simple convex transformation. It orthogonalizes the population, making it easier to decode.
