Assessment

Why?

Strongest counted support: The study reports anatomically distinct, oppositely directed medial and lateral OFC signals before approach decisions in six implanted patients. weight 2.000000 evidence

Suppressed as dependent: The quoted passage directly supports opposing medial and lateral OFC activity before approach in the gamified task.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Leans supported.

Qualifications

• The study sampled six clinically implanted patients across UCSF and WUSTL, with electrode placement guided exclusively by clinical needs.

  Limits sample and electrode-selection generalization.

• The experiment used a six-second gamified approach-or-avoid decision epoch after a 600-millisecond pan-in period.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
