🤖 Can algorithms ACTUALLY recognize how we feel from the way we talk in naturalistic settings?
🎙️ We find that voice prosody reveals only limited information on affective experience and is outperformed by semantic content.

See our new chapter on how to collect and analyze data from mobile apps for research in psychology (with my great co-authors @ClemensStachl and @LarissaSust)!
Excited to announce our chapter on "Mobile Application Usage in Psychological Research" is now available in the freshly published handbook on "Mobile Sensing in Psychology" by @guilfordpress.

In a NEW PAPER out today @NatureHumBehav we show that some of the most popular strategies for increasing happiness are not well-supported by rigorous scientific evidence. A thread. xitter.cf/NaturePortfolio/status…
Some of the most commonly recommended happiness-increasing strategies in the media, such as mindfulness and exercise, have a weak basis of scientific evidence, suggests a systematic review published in @NatureHumBehav. go.nature.com/3K8x9q9
I'm thrilled to announce that I've successfully completed my PhD journey 🎉🥳
Huge thanks to my amazing supervisors, Markus Buehner and @ClemensStachl!
As one chapter ends, another begins. I'm grateful to continue my academic journey as a PostDoc at @HSGStGallen🇨🇭

Great paper for teaching & learning. Tell students: “Your goal is to feel awkward and uncomfortable.”
Giving an explicit goal of aiming to feel uncomfortable in order to grow makes folks persist in classes, write better, seek out more info & learn more from political opponents.
Timo Koch retweeted
Our new work is another piece of evidence that worrying about large scale AI-powered misinfo and mechanized persuasion hitting political and democratic processes like a tsunami in the near future is very much in order.
Scholars study how persuasive AI chatbots are. “These concerning findings call for immediate consideration of regulations of the use of AI for political activities.” stanford.io/3ZY302h

#GPT3 and #ChatGPT can produce appeals that persuade humans on political issues (even highly polarized ones), with effect sizes similar to appeals written by humans. New research from our lab, with @baixx062, @jgvoelkel, and @JEichstaedt. 🧵👇
New WP: 🚨Artificial Intelligence Can Persuade Humans on Political Issues🚨Large language models (like #ChatGPT and #GPT3) are changing the world. Here we show that GPT3 can write messages that change people’s attitudes on important policy issues osf.io/stakv 🧵1/11
Happy to have contributed to this new paper on how non-task expert physicians (i.e., non-radiologists) benefit most from correct explainable #AI advice when reviewing X-rays 🏥 🤖
Findings show nicely how AI can help improve workflows and patient safety in #healthcare
AI-enabled clinical decision support systems (#AICDSS) may improve efficiency and patient outcomes. #AIinHealthcare
New study by Gaube et al. shows non-task expert physicians benefit from correct explainable AI advice for X-rays.
