In the thirteenth Cognitive Webinar, we welcomed Patrick Haggard (PhD) from College Londan to talk about the "post-Libet Experiment and Free Will". In the talk, we first considered what Haggard has observed through his own experimental work and the criticisms of the simplicity of Libet's experiment. His new measurements and experiments confirm Libet's findings. We tried to interpret scientific approaches to volition in three ways that could enrich the scientific understanding of volition. In the final topic of the talk, we thank Haggard for accepting our invitation to talk about how the view of volition can be related to individual autonomy and responsibility. We hope to see you again, our participants, who listened to the talk and enriched it with their questions and comments!
