Sense of agency and Time Perception

My master’s work centered on the sense of agency, particularly the phenomenon of intentional binding (IB), which refers to the temporal compression between one’s voluntary action and its sensory consequence.

The project investigated how much of the temporal compression between action and outcome is due to sensory characteristics rather than one’s sense of control. Using a modified Libet Clock paradigm, we systematically examined how changes in the sensory modality of the outcome (e.g., visual versus auditory) affect the magnitude of IB.

We discovered that the magnitude of IB changes across outcome modalities and visual information tends to dominate the effect in the audiovisual context. The results highlight the importance of sensory characteristics to temporal cognition and raise questions about the use of intentional binding as a measure of agency.

The results of the project have been published as my first journal article.
