The self in motion: The advantage for one's own movements at an implicit but not explicit level

Area of Science:

• Cognitive Neuroscience
• Body Representation
• Self-Awareness

Background:

• The distinction between self and other relies on integrating visual and sensorimotor body representations.
• A self-advantage effect exists for recognizing one's own body parts in implicit tasks, but not explicit ones.

Purpose of the Study:

• To investigate if a similar self-advantage effect occurs for implicit recognition of self-generated body movements.
• To explore the role of sensorimotor mechanisms in implicit self-recognition.

Main Methods:

• Participants performed implicit and explicit tasks judging schematic body movements.
• Implicit task: judge if movements were same or different.
• Explicit task: judge if movements were their own.

Main Results:

• A self-advantage effect was observed in the implicit task: faster and more accurate recognition of self-movements.
• This facilitation in self-movement recognition was absent in the explicit task.
• Results indicate a dissociation between implicit and explicit self-motion recognition.

Conclusions:

• Motor information significantly contributes to self-awareness and body representation.
• Sensorimotor mechanisms play a crucial role in the implicit recognition of the bodily self.
• Findings support the integration of sensorimotor and visual information for self-body distinction.
