⚠️ Warning: Joining our team as a postdoc has a known side effect of receiving multiple job offers shortly after. We currently have 3 such cases. ​If you are willing to take that risk, applications close in 1 week. The upside is you'll be in a supportive and stimulating environment in munich.

Publication alert! Our latest paper with @kristinwitte.bsky.social and @ericschulz.bsky.social is out in Scientific Reports: rdcu.be/eydDQ! We explore whether model-based exploration strategies can be used to capture individual differences. Curious how cognitive models meet personality science?

ChatGPT gets ‘anxiety’ from violent and disturbing user inputs, so researchers are teaching the chatbot mindfulness techniques to ‘soothe’ it
A study on how to “calm down” chatbots could advance how AI is applied in mental health interventions, according to the authors.

Thank a lot! That is very interesting indeed. We also found that across all tasks the model-free switch probability (probability of choosing a different option than on the previous trial) is more reliable and has greater convergent validity. Very happy to discuss more about this.

In sum, we show that simplified modelling and creating latent factors improves robustness. Still, extracted strategies are more linked to working memory than real-world exploration, raising questions about the validity of few-armed bandit tasks for studying exploration.

Kristin Witte @kristinwitte.bsky.social · 10/12/2024
Our changes improved the convergence of exploration strategies across tasks. The latent factors were however still not related to any self-reported measures of exploration or to any psychiatric constructs. They did however show a strong correlation with working memory capacity.

Kristin Witte @kristinwitte.bsky.social · 10/12/2024
We subsequently made two main changes to the analyses: 1) We simplified and unified the computational modelling for the Horizon task and the 2-armed bandit. 2) We constructed theoretically informed latent constructs for the exploration strategies across all tasks.

Kristin Witte @kristinwitte.bsky.social · 10/12/2024
When using the standard modelling approaches, the test-retest reliability of all model parameters and most task measures was rather poor. We also found low correlations between model parameters from different tasks, despite these parameters measuring the same strategies.
100
Kristin Witte @kristinwitte.bsky.social · 10/12/2024
We tested these requirements by collecting data on three bandit tasks, five questionnaires and three working memory tasks. We retested participants on all tasks after 6 weeks, to test for temporal stability.

Kristin Witte @kristinwitte.bsky.social · 10/12/2024
This type of approach is very valuable. However, for treating individual differences in model parameters as cognitive traits, we need the model parameters to be: 🕐stable over time 🔗converging across tasks 📋related to real-world exploration

Kristin Witte @kristinwitte.bsky.social · 10/12/2024
A growing number of studies uses few-armed bandit tasks to test how people explore. Recently, an increasing body of research (including our own) turned to individual differences in this behaviour and related model parameters to questionnaire measures of psychiatric traits.

Kristin Witte @kristinwitte.bsky.social · 10/12/2024
Preprint alert! We explore 3 exploration tasks, testing if they measure a stable construct & its link to real-world exploration. We find improved robustness of latent factors compared to single-task estimates. With Mirko Thalmann & @ericschulz.bsky.social 🔗https://osf.io/preprints/psyarxiv/tzuey
