A little bby from my PhD is published!

we did a complex study to answer a simple Q:
do day-to-day feelings impact choices?

A: Yes. When feeling motivated (independent of other stable or unstable feelings) choices changed because rewards seemed greater.

As the world grows scarier, let's talk about social connection!

We review its role in addiction & how it's influenced by opioids, now out in Biological Psychiatry (special issue on social homeostasis)

It's @loseth.bsky.social's brainchild & covers A LOT🧠

Overall, our results challenge the notion that individuals exhibit prosocial apathy when effort is required to help others and suggest that the type of incentive (avoiding harm vs. increasing wealth) is a key factor in shaping effortful prosocial behavior.
clamassaccesi.bsky.social
Last, using computational modelling, we show little credible evidence that discounting of pain reduction by effort differs between self and other
clamassaccesi.bsky.social
Participants also exerted a similar amount effort to reduce their and the other's pain, indicating that this prosocial motivation to protect others’ form harm extends beyond decision-making to action invigoration
clamassaccesi.bsky.social
We showed that when pain reduction is the outcome of the prosocial act individuals are similarly willing to mobilize effort to help themselves and a stranger
clamassaccesi.bsky.social
Prior research suggested that when effort is required to help, individuals become prosocially apathetic. Here we adapted a well-validated prosocial effort task (pubmed.ncbi.nlm.nih.gov/28819649/) and we examined if this is the case also for non-monetary rewards, i.e. reducing other’s pain
