A shame to only tweet papers 'hot off the press'. Today I enjoyed re-reading @valentinwyart, @KiaNobre & @summerfieldlab, illustrating - perhaps c.intuitively - how increasing sensitivity to expected features makes one a biased (not 'better') observer:https://www.pnas.org/content/109/9/3593 …

Thanks for this Daniel! One of the times when I felt our particular design (filtered visual noise + reverse-correlation analysis) was truly useful to falsify a pervasive hypothesis - in this case, that expectations only produce ‘late’ effects on perception.

Replying to @valentinwyart @danieljamesyon and
I love that design. We are currently running an adaptation of it to examine effects of aversive conditioning in lieu of task relevance (orientation indicates CS+ or CS-). So far we replicate probability bias & find more sensitivity to signal energy for CS+in signal absent trials.
