After scrolling Twitter, it will take you a while to get back into work mode. Why? In our new work (now out in Psych Rev) with @JasonLeng5, @smusslick, @amitaishenhav, we explore the costs of adjusting cognitive control to meet different goals: https://t.co/UyrqGJOD8G

Our newest chapter, “Breaking the tug-of-war,” reviews the lab’s latest @NIH- and @NSF-funded research that has changed the way we think about decision-making (and we hope how you do also): https://t.co/9icpvmaNtn

Led by @JasonLeng5, along  with @YiHsinSu1 and @froemero1

Our paper is finally in press! Many thanks to @froemero1, Thomas Summe, @amitaishenhav, and everyone in @ShenhavLab!

Xiamin Leng and colleagues find that framing options in a choice set as inclusive (instead of mutually exclusive) increases the efficiency of choices and reduces feelings of conflict.

All in all, these studies show that choices can improve and feel less costly when enacted as though there are still other options possible. These benefits result from options no longer competing as strongly with one another, relieving a major source of tension in choice.

Excited to share my latest preprint with @froemero1, Thomas Summe, & @amitaishenhav:
“Mutual inclusivity improves decision-making by smoothing out choice’s competitive edge” https://t.co/AMf1O0X57C

A short 🧵

[Xiamin (Jason) Leng @JasonLeng5]

Another way people have been shown to facilitate choices is to set a tight deadline. We confirm that this is the case. However, we find that this process is enacted via a different decision mechanism than inclusivity, and led people to feel more, rather than less, conflicted.

We’re looking for a new postdoc! If you’re interested in how people make cost-benefit decisions, including about mental effort, this offers the chance to explore such questions using multiple (neural, comp) methods with an amazing group of people. Pls RT! https://t.co/kYmRG53fdJ

Excited to share my first preprint “Dissociable influences of reward and punishment on adaptive cognitive control” looking at how reward and punishment modulate cognitive control allocation in a new temporal cognitive control task!
