Summary
Conscious experience of intentional action relies on predictive links between intentions and outcomes, not retrospective inference. This finding is crucial for understanding agency and motor control.
Area of Science:
- Cognitive Neuroscience
- Philosophy of Mind
- Psychology
Background:
- Intentional action involves neural processes and a conscious sense of agency.
- Motor prediction models are key to understanding neural control and conscious experience of action.
- The relationship between neural events and the subjective experience of authorship is not fully understood.
Purpose of the Study:
- To investigate the relationship between neural and phenomenal events in intentional action.
- To determine if conscious experience of action depends on precise prediction matching or retrospective inference.
- To explore the role of predictive processing in the sense of agency.
Main Methods:
- An experiment was conducted with normal subjects judging perceived timing.
- Subjects assessed the timing of intentional actions, involuntary movements, and subsequent auditory tones.
- The study manipulated the continuity of intention and action by introducing involuntary movements.
Main Results:
- Intentional action led to 'intentional binding,' a temporal link between action and effect perception.
- Interrupting intention with involuntary movement abolished this temporal binding.
- The presence of an appropriate predictive link between intention and effect was critical.
Conclusions:
- The phenomenology of intentional action requires a predictive link between intentions and their consequences.
- Conscious authorship of action is not based on retrospective inference but on predictive processing.
- These findings advance our understanding of agency, prediction, and conscious experience in motor control.
