In addition to making the leap to Mastodon, this year I am also leaping to a new position at the University of York. I'm rejoining the department of psychology almost 20 years after first starting my undergraduate there. A very happy homecoming.

Computational modelling of the BART task revealed no relationship between risk-taking or prior belief parameters and Catastrophizing scores. This might be due to the parameters of our model not fully explaining the risk-taking captured by the task.

In sum, individuals who catastrophize may perceive the probability of a negative outcome as higher, whether this is in a risky situation, or in one that is simply uncertain, resulting in apparent risk avoidance.

We measured participants' levels of catastrophizing with the catastrophizing scale (2021 by @alexandra_pike They also played a modified Balloon Analogue Risk Task (BART), where they had to win points by pumping the balloon up, which increased the risk of bursting.

Catastrophizing is when an individual overestimates the probability that a catastrophe will occur. Decatastrophizing has been used extensively in CBT to treat depression and anxiety, but we don’t know much about the cognitive underpinnings of catastrophizing.

Research has previously shown that risk aversion is elevated in anxiety (see the 2017 paper by @caro_charp et al). We hypothesized that catastrophizing may drive the relationship between anxiety and risk aversion.

Does catastrophizing make you less likely to take risks? Read our new paper ‘Catastrophizing and Risk-Taking’ to find out! @CPSYJournal: http://doi.org/10.5334/cpsy.91 @alexandra_pike , Nina Peleg, @olirobinson

Hi Mastodon - my first tweet (or how do you call it?) Is a big one: I am moving to take up a professorship at the university of Tübingen!
I have several positions to fill and if you want to know more - have a look at the (old school) twitter thread here: https://twitter.com/TobiasUHauser/status/1617817409402068992?t=BbuI3cbzByl63cnFyKHrkQ&s=19

First time with in-person participants as PI! Feels like a big milestone.

In response to helpful feedback from reviewers and readers, we have updated our preprint on #Bayesian repeated-measures ANOVA. Relevant if you have ever conducted one with {BayesFactor}, JASP, or Jamovi.

We hope it's now clear that the issue discussed is one of model specification and comparison—not a Bayes vs. Frequentism one.

We now also discuss a third model specification approach and discuss how to choose between them.

Passed my #PhD #viva with minor corrections! Very happy!! 🎉 Many thanks to my examiners Profs Nicola Walshe and Jamie Pearce! I was nervous, of course, but they really made this #exam a nice and enjoyable experience! I celebrated with some beers 🍻 and am now ready to focus on my new job at #UCL #psychiatry (which is going very well so far) 👍
