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.

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

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.

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.

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.
