Experimental analysis shows low-dimensional representations arise during working memory processing in decision tasks, suggesting new computational roles in learning.
Key Points
MAIN FINDING: Working memory influences neural geometry and leads to low-dimensional representations during learning.
KEY EVIDENCE: Participants transformed sensory information into abstract forms while solving an XOR task.
APPROACH: EEG recordings from 25 participants were used to study the effects of working memory on decision-making tasks.
SIGNIFICANCE: These findings suggest a novel role for working memory in shaping representations that facilitate learning and decision-making.
