Overview

Examines how evaluation direction influences decision-making processes, indicating flexibility in value assignment.

Key Points

  • The study investigates how shifting evaluation direction affects decision-making processes and their underlying cognitive and neural dynamics.
  • Recruited 36 participants for a value-based binary choice paradigm.
  • Manipulated evaluation direction through task framing.
  • Analyzed behavioral responses using hierarchical drift diffusion modeling and EEG.
  • Low-value evaluations led to longer reaction times and slower evidence accumulation.
  • Distinct neural signatures emerged, including enhanced N200 and centro-parietal positivity in low-value conditions.
  • Increased alpha and beta desynchronization indicated greater attentional resource demand.
