3/3 Here we show that their deconvolution approach eliminates these same signatures when applied to a ground-truth EA signal. We also recap the many other signatures of sensory EA that the CPP has been shown to exhibit.

2/3 Frömer et al (2024) used a signal deconvolution method to show that one signature of evidence accumulation (EA) observed in the centro-parietal positivity (CPP) - trial-averaged response-locked buildup effects - could arise artifactually from overlapping stimulus- and response-locked components.

Check out our new paper in which we identify a model that can jointly account for the timing and accuracy of perceptual choices, the timing and level of subsequent confidence judgments and the pre- and post-choice dynamics of neural decision signals

“Regressing common choice signals away does not make them artifacts" Please check out our commentary on the Frömer et al paper (2024, Nature Human Behaviour) in which we highlight important problems with the analysis and interpretation of their perceptual choice data. www.biorxiv.org/content/10.1...

Regressing Away Common Neural Choice Signals does not make them Artifacts. Comment on Frömer et al (2024, Nature Human Behaviour)

The recent paper by Frömer et al (2024, Nature Human Behaviour) examines a component of the event-related potential (ERP) known as the centro-parietal positivity (CPP) that has been widely implicated ...

Our results have interesting implications for modelling 2 choice and continuous outcome dot motion tasks, and open the door to future research to help further develop our understanding of ODMR 5/5

We found supporting evidence that temporal filters are involved in ODMR, with the higher frame rate display seeming to induce more ODMR than the lower frame rate display. Confidence data interestingly distinguished ODMR both from error and correct responses. 4/5

Inspired by Bae and Luck's 2022 Visual Cognition paper, we decided to investigate if changing the display frame rate would impact ODMR rates - hypothesising that temporal filtering may be involved. We also gathered confidence data to compare ODMR to correct and error responses. 3/5

Pat was frustrated at consistently responding in the opposite direction to the true dot motion direction displayed during piloting for a related study. Diving into the literature revealed he was not the only one responding in such a way. 2/5

New paper from our very own @patmckeown.bsky.social in Visual Cognition, investigating opposite direction motion reports (ODMR) in RDKs. We looked at the role of display frame rate and confidence in these peculiar reports. 1/5 w/ Elaine Corbett and @redmondoconnell.bsky.social
