LIT-1438: The current status of research on the structure of evaluative space

StatusActive — read 2026-10-23 (NOTE-1101): in full, from the NIH author manuscript in PubMed Central (PMC2894997, NIHMS165251). Worth reading as the evaluative space model's own later summary, written with Berntson and Cacioppo. Positivity and negativity are separable systems, whose combined output is a bipolar predisposition to approach or withdraw. They can be activated reciprocally, independently or together, and coactivation is ambivalence. Ambivalence and neutrality give the same middling output from different underlying states. Negativity has the higher gain and positivity the higher intercept. It stands in for the unread 1994 and 1997 papers (LIT-1453, LIT-1456).

ExtendsLIT-1456 — Beyond Bipolar Conceptualizations and Measures: The Case of Attitudes and Evaluative Space
SupportsCLAIM-440 — An organization's appraisal is the negotiation among its perspectives, a common currency is that negotiation's admitting an ordering of the options it faces, and goal-conduciveness valence is a regime in which an ordering of the organization's own states by their bearing on its maintenance prevails in the negotiation; so valence presupposes contested rankings, not frustrated demands, its sign is whether the organization runs ahead of or behind a reference course along the potential ordering, its intensity is how far the negotiation's decisions follow that ordering, and ambivalence, where no ordering prevails, differs from neutrality, where one prevails and the organization keeps to its course

Key takeaways

  • Separable channels, bipolar output. Behaviour “may be constrained to a single bipolar dimension” of approach and withdrawal. The mechanisms feeding it are two systems, positivity and negativity, that are “not equivalent in their constitution, operations, or consequences” (functional separability). Their combined outputs “produce a behavioral predisposition to either approach or avoid the stimulus”.
  • Three modes. “Positivity and negativity can be reciprocally activated, independently activated or co-activated” (Table 1). Reciprocal activation is the usual mode and is the more stable one (energetic efficiency).
  • Ambivalence is coactivation. Coactivation is “objective ambivalence”, “resulting in a conflict between approach and avoidant behaviors”. It is “generally rare and highly arousing, as they provide indeterminant guidance for behavior”. Fast oscillation between opposite stimuli produces the same state, acting as a low-pass filter.
  • Neutral and ambivalent give the same output. On the response surface (Figure 2), the coactivity diagonal “which represents different evaluative processes (e.g., neutral to ambivalent) – yields the same middling expression”. The mapping from evaluative space to output is many-to-one.
  • Asymmetric activation functions. The gain for negativity is higher (negativity bias), and the intercept for positivity is higher (positivity offset). Both recalibrate with context, like light-adaptation in vision.
  • Heterarchy. Evaluation is represented from the spinal cord to the frontal lobes. At low levels responses may be constrained to reciprocal activation. “higher levels of the neuraxis have the ability to override these dominant responses”.
  • Clinical. Depression and anxiety differ in which channel is dysregulated: heightened negativity in both, and diminished positivity in depression.

Standing in the record

Filed on 2026-10-23 for the record’s proposal that hedonic valence is one ordering serving as the negotiation’s potential (CLAIM-440, TERM-076). That proposal separates ambivalence from neutrality, and the evaluative space model did so first. It is the only first-hand statement of the model the record could reach lawfully: the 1994 and 1997 papers are Unavailable. The bearing is set out in NOTE-1101. In short:

  • the model anticipates the distinction;
  • it locates ambivalence in the activation of two channels, not in a failed or split ordering;
  • its output is always an ordering, a net approach–avoid predisposition;
  • its asymmetries are something the proposal’s symmetric sign clause does not predict.

The record’s other dimensional account, Barrett’s (LIT-1353, LIT-542), takes valence as one bipolar dimension of core affect. This model denies that.

No instruction for machine-learning practice; nothing here belongs in the anthology.
