First preprint of my PhD! Thanks for amazing supervision from Clayton Curtis and all the cool people from Clayspace lab and help from everyone at NYU CBI without which this work would not have been successful. biorxiv.org/content/10.1101/…
Perturbing human V1 degrades the fidelity of visual working memory

Perturbing human V1 degrades the fidelity of visual working memory

The main function of working memory is to extend the duration with which information remains available for use by a host of high-level cognitive systems [1][1]. Decades of electrophysiological...

Before 2023 is over, here's another new preprint from me! In it, we attempt to elucidate the neural mechanisms of cognitive effort exertion on a working memory task. biorxiv.org/content/10.1101/…
Trying harder: how cognitive effort sculpts neural representations during working memory

Trying harder: how cognitive effort sculpts neural representations during working memory

The neural mechanisms by which motivational factors influence cognition remain unknown. Using fMRI, we tested how cognitive effort impacts working memory (WM). Participants were precued whether WM...

I have to acknowledge my amazing co-author @lindromat, who contributed a really cool analysis linking whole-brain delay period activity to decoding from visual cortex.

I also have to thank my mentor Clay Curtis, who from day 1 of my PhD was 100% on board with me pursuing my passion & studying all things cognitive effort. Clay is the real MVP!!!

Happy to share that our preprint titled “Policy abstraction as a predictor of cognitive effort” with @jordan_rubimac & @badrelab is out! In this work, we establish a performance-independent task feature that is predictive of cognitive effort avoidance psyarxiv.com/by7gk/ 1/15

Wagers for work: Decomposing the costs of cognitive effort

Wagers for work: Decomposing the costs of cognitive effort

Some aspects of cognition are more taxing than others. Accordingly, many people will avoid cognitively demanding tasks in favor of simpler alternatives. Which components of these tasks are costly,...

In this work, we use a novel task & computational model to perform cost decomposition on the N-back, revealing what makes it so subjectively costly for subjects to perform!

Interestingly, we find that specific working memory operations (like updating) are costly in themselves, independent of other potential costs, like error aversion, time on task, or feelings of fatigue.

New preprint with @milenamr7 and @Anne_On_Tw showing that age differences in learning were largely attributable to changes in a working memory system that was associated with levels of prefrontal glutamate! Congrats!!🎉 elifesciences.org/articles/8…

Age-related differences in prefrontal glutamate are associated with increased working memory decay...

Apparent age-related differences in learning are best accounted for by rapid decay of information in working memory, which is associated with levels of prefrontal glutamate.
