|
|
||
| ### Key Takeaways | ||
| 1. **Choice-Induced Preference Change:** Validated at both behavioral and neural levels. | ||
| 2. **Neural Correlates:** | ||
| - The anterior cingulate cortex (ACC) and dorsolateral prefrontal cortex (DLPFC) track cognitive dissonance. | ||
| - The anterior ventral striatum encodes post-choice changes in preferences. | ||
| 3. **Behavioral Impact:** Actions do not merely reflect preferences—they shape them. | ||
