Self-other distinction (SOD) processes for motor, cognitive, and affective representations are largely distinct, with limited overlap with cognitive control. This complexity has implications for understanding disorders involving SOD deficits.
Area of Science:
- Cognitive Neuroscience
- Social Psychology
- Neuroscience
Background:
- The self-other distinction (SOD) is crucial for differentiating self from other mental representations.
- Unresolved questions exist regarding shared processes across different SOD domains and overlap with cognitive control.
Purpose of the Study:
- To investigate if motor, cognitive, and affective SOD share underlying processes.
- To examine the overlap between SOD and domain-general cognitive control.
Main Methods:
- An online study with 243 participants.
- Utilized three SOD tasks (automatic imitation inhibition, visual perspective-taking, emotional egocentricity bias) and two cognitive control tasks (Stroop, stop-signal reaction time).
- Employed correlation, hierarchical clustering, and multidimensional scaling analyses.
Main Results:
- No significant associations were found among motor, cognitive, and affective SOD indexes.
- Hierarchical clustering revealed distinct SOD clusters.
- Multidimensional scaling suggested a potential two-cluster tendency, with motor and cognitive SOD showing some proximity.
- Cognitive control tasks (Stroop, SSRT) showed limited or no association with SOD measures.
Conclusions:
- SOD processes for motor, cognitive, and affective domains appear largely independent.
- There is minimal overlap between SOD and domain-general cognitive control processes.
- Findings highlight the complexity of SOD and its relevance to clinical disorders.
