Summary

In this talk, Marta Gerosa presents her PhD project investigating the influence of cardiorespiratory fluctuations on sense of agency, specifically focusing on the intentional binding effect. She explains that sense of agency refers to the experience of being in control of one’s actions and their consequences, and that intentional binding is a measure of this, where the perceived time between an action and its outcome is compressed. The project aims to explore whether voluntary actions are preferentially initiated in specific phases of the cardiac and respiratory cycles, and whether this influences the sense of agency. Preliminary results from a pilot study show that intentional binding effects are present, with both action and tone binding observed. The analysis pipeline for ECG data has been developed in Python, and future analyses will include circular statistics and binary analysis to examine the modulation of binding by cardiac and respiratory phases. The study is pre-registered on OSF, and data collection is ongoing. The talk concludes with a Q&A session where predictions and future directions are discussed.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides valuable insights into an emerging area of research linking interoceptive signals to sense of agency. The argumentation is solid, grounded in existing literature and a clear theoretical framework. The presenter acknowledges the preliminary nature of the results and outlines a rigorous analysis plan. The discussion of potential mechanisms and predictions adds depth to the presentation.

Scientific Rigor, Source Quality, Title Accuracy

The scientific rigor is evident through the mention of pre-registration and the use of established measures like intentional binding. The sources cited are not explicitly listed, but the talk references prior literature and the OSF pre-registration. The title accurately reflects the content, focusing on body-brain interactions. The presentation is well-structured and transparent about the ongoing nature of the research.
