Disappointment

EB04 Loss & Separation
Emotional LayerMML-4

Version v2.0

Definition

An episodic response triggered by a negative discrepancy between expected and obtained outcomes, organizing disengagement, recalibration of expectations, and reprioritization.

Mechanism

Expectation-outcome comparator detects negative mismatch; motivation toward the target drops while recalibration system activates.

Trigger–Appraisal–Function

• Trigger: Outcome falls below expectation or promise.
• Appraisal: “I expected better / this didn’t deliver.”
• Function: Recalibrate expectations, reallocate effort, and update plans.

Observable Output

• Drop in motivation toward the target; disengagement or reprioritization.
• Attention to discrepancy and ‘what went wrong’ (brief).
• Reduced enthusiasm; muted affect; may prompt corrective planning.
• Somatic: deflation/low arousal.

Episode Profile

Onset: minutes. Peak: deflation drop; sometimes sharp. Duration: minutes–hours. Recovery: resolves with new plan or acceptance; may slide into sadness if loss is irreversible. KEY METRIC: magnitude of motivation drop; time to replan.

Dysregulation Risk

Chronic overexpectation cycles; self-blame turning into shame.

Change Potential

Regulation Trainability = High. Susceptibility Shift = High (expectation calibration, forecasting skill).

Empirical Anchor

Expectation violation theory; disappointment in decision research (van Dijk & Zeelenberg, 2002).
