Health Motivation & Outcome Expectations

← Back to Domain-Specific Families

Abstractions about expectancy, perceived value, confidence, nocebo responses, action planning, policy judgment, and prioritization of outcomes.

6 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Expectancy-value theory — A family of motivation and choice models in which behavior depends jointly on expected success or outcome and the subjective value assigned to that outcome or task.
• Health action process approach — A stage-based health-behavior theory separating motivation to form an intention from volitional planning, action and maintenance processes.
• Nocebo — Worsening symptoms or adverse outcomes caused or amplified by negative expectations, conditioning and treatment context rather than the specific harmful action of an intervention.
• Outcome primacy — A learning bias in which the result of an initial experience with a task exerts disproportionate and persistent influence on later choices and probability weighting.
• Overconfidence effect — Miscalibration in which confidence, perceived performance, comparative rank, or precision systematically exceeds warranted accuracy.
• Policy capturing — A judgment-analysis method that fits a statistical model to repeated decisions in order to estimate how a person weights available cues.
