From Body to Brain and Back: Multimodal Evidence for Interoceptive Alterations in Schizophrenia Spectrum Disorders When the brain and body misalign, emotional experience and sense of reality can be disrupted. Although such atypical experiences are central to schizophrenia spectrum disorders (SSD), interoception, p...

How the brain listens to the body matters.
Our new preprint investigates interoceptive processing in schizophrenia spectrum disorders across phenomenology, behavior, and heartbeat-evoked brain responses. 🧠🫀DOI: doi.org/10.64898/202...

Our studies confirmed AffectTracker is reliable, with high user experience and low interference. It opens new avenues for linking subjective experience to physiological dynamics. The tool is open-source and available on GitHub!
#OpenScience

AffectTracker allows users to continuously rate their valence and arousal during VR experiences. It features customizable feedback options, including a simplified affect grid and a novel abstract shape ("Flubber"), designed to be intuitive and minimally interfering.

📢Our peer-reviewed article about the AffectTracker is finally out! 😲🕹️📈
Traditional methods for rating emotion often miss the dynamic, moment-to-moment nature of feelings. We designed a tool to capture this continuous affective experience in real-time during dynamic emotional stimulation.

📣 We're at the #MindBrainBody Symposium in Berlin, starting today! Looking forward to connect with everyone and share our latest research 🧠

Our group has an exciting lineup of posters - come chat with us! 💬 Check out the previews below to see where and when to meet us 📌

The 1-min videos in study 1 are monoscopic, chosen as intermediate stimuli between static images and long videos to extend the classical short event-related stimulus approach. Also finding suitable free videos was challenging. Study 2's 23-min video is stereoscopic, a step further in stimuli type

3️⃣Tool offers a novel way to study affective dynamics with minimal interference, effectively capturing the nuances of subjective experiences. It opens new research opportunities to link affective states with physiological dynamics
🌟Stay tuned for the full paper & we welcome feedback & discussions! 💭

2️⃣Empirically evaluated in 2 studies at 2 sites (Berlin & Torino; N = 134) with both shorter 1-min 360° videos (low affective variability [AV] 〰️) and longer more dynamic 23-min stimulus (high AV 📈)
Both Grid & Flubber ➡️ high user experience 😃 & low interference with the affective experience itself

1️⃣Participants can rate in real-time and continuously, using the touchpad or joystick of a VR controller 🎮(here: HTC Vive Pro). It comprises three customizable feedback options: a simplified affect grid (Grid), an abstract pulsating variant (Flubber), and no visual feedback (Proprioceptive)

Title: Real-time continuous rating of affective experience in immersive Virtual Reality

P.361 (Session 1)
@toninfrc.bsky.social

In collaboration with Torino University, we developed a fun and intuitive new tool to record moment-by-moment feelings!

We are coming to Psychologie und Gihirn 2024 (PUG) in Hamburg! Come chat with us! See the some teezers in the comments 💬 #PuG2024

Thank you!

We contribute to shed light on the complex relationship between emotions & the nervous systems (or MindBrainBody coupling) under naturalistic stimulation. 🌟 Stay tuned for the full paper & we’re very happy about feedback and discussions! 💭
