Definition

A somatic marker is a bodily value tag associated with a scenario or remembered outcome that biases choice toward or away from an option. In the Damasio-attributed account, reactivated body-state patterns help reduce an otherwise unmanageable decision space. RB2 allows neural simulation as well as actual bodily responses; the disputed gambling-task mechanism is not treated as settled proof.

Explanation

AB introduces markers through Damasio's patient Elliot and describes felt warmth or dread as bodily records of earlier outcomes. Its card-game illustration is explicitly qualified: later studies found conscious knowledge earlier than the original interpretation allowed, so the example is used as illustration rather than proof. RB2 develops the hypothesis, including simulated or actual body-state reactivation, and its native note distinguishes the contested mechanism from the clinical profile it reports.

RB3 applies the account to weighting and stakes: Elliot could enumerate options without valuing them adequately, whereas action requires differential weight. The subsequent distinction is crucial: representing a value, being weighted by it and having something matter are different achievements. Functional weighting in current AI does not establish felt valuation.

PB's reproduced AI exchange merely lists Damasio's somatic markers among approaches missed by a hardware-only understanding of embodiment. It supplies attribution and a local occurrence, not an independent account of the mechanism. AB also explicitly borrows Damasio's physiology without adopting his verdict on the hard problem of consciousness; marker use should not imply wholesale doctrinal agreement.

Scope and attribution

Substantive support belongs to AB, RB2 and RB3. PB is an attributed AI-exchange mention only. No RB1 treatment was found; generic markers and the hypothesis identity are not aliases.

AB — The Actual Book

Bodily tags bias options through remembered outcomes. The task illustrates rather than proves the account, and the notes limit agreement with Damasio on consciousness.

Occurrence locators: 80, 81, 157; Thinker register: 228; Notes: 240, 245.

PB — The Possible Book

Mention-only in a reproduced AI exchange: Damasio's markers are listed among approaches missed by hardware-only embodiment.

Occurrence locators: Reproduced AI exchange: 15.

RB2 — The Real Book, Volume II: Becoming Is Being

Actual or simulated body states guide complex choice. Clinical and gambling-task discussions retain criticism of the proposed mechanism.

Occurrence locators: 15, 16, 17, 18, 27, 34, 37, 38, 39; Notes: 17.

RB3 — The Real Book, Volume III: Murmurations

Markers make decision spaces manageable, but functional weighting is distinguished from felt valuation.

Occurrence locators: 164, 165; Reproduced AI exchange: 398.
