Commitment Mechanics Slides Psychology of Relationships
The Investment Model of Commitment Processes
Why do people stay? Beyond satisfaction to the mechanics of persistence.
Graduate Seminar
Research Focus: Caryl Rusbult
The Persistence Paradox
"Commitment is not just the desire to stay, but the psychological state that represents a long-term orientation toward a relationship."
The Central Inquiry
Why do individuals remain in relationships that are objectively unsatisfying, high-conflict, or even abusive?
Thesis: Satisfaction is only one of three critical pillars supporting commitment.
The Structural Model
Satisfaction
Degree of positive vs. negative affect experienced. Does this relationship meet my needs?
Alternatives
Quality of perceived alternatives. Could my needs be better met elsewhere (or alone)?
Investment
Resources linked to the relationship that would be lost or decline in value if it ended.
Commitment = (Satisfaction - Alternatives) + Investment
The "Sunk Cost" of Love
Extrinsic Investments
Shared possessions and mutual finances
Social networks and community ties
Children and co-parenting structures
Intrinsic Investments
Time and emotional energy expended
Self-disclosure and shared history
Personal identity fusion ("We" vs "I")
Le & Agnew (2003) Meta-Analysis
Correlation with Commitment
Satisfaction Level r = .68
Investment Size r = .46
Quality of Alternatives r = -.48
Finding: The model explained 61% of the variance in commitment across 52 independent samples (N = 11,582).
The model holds across marital status (married vs. dating), gender, and sexual orientation, proving its robustness as a universal mechanism for persistence.
Why do they stay in abusive relationships?
The Rusbult & Martz (1995) Study
Interviewed women at a shelter for domestic violence. Commitment (intent to return to partner) was predicted not by the severity of abuse, but by:
Predictor 1
Higher investments (e.g., married, children, longer duration)
Predictor 2
Poor alternatives (e.g., lower education, no independent income, nowhere else to live)

Model Parameters: The Investment Model
In this exercise, we will apply Rusbult’s Investment Model to three distinct case profiles. Recall that commitment is hypothesized to be a function of three variables: Satisfaction Level (S), Quality of Alternatives (Alt), and Investment Size (I). The formulaic representation is: C = (S - Alt) + I.
Case Profile Alpha: "The Inertial Marriage"
PROFILE TYPE: HIGH STABILITY
Satisfaction
"We don't really argue, but we don't have much to say to each other. It's fine. 4/10."
Alternatives
"The dating scene seems exhausting. Being alone sounds lonely. 2/10."
Investment
"We've been together 15 years, share a mortgage, and have three kids. 9/10."
Task: Predict the Commitment Level and provide a psychological rationale based on the interplay of variables.
Case Profile Beta: "The High-Peak Fling"
PROFILE TYPE: VOLATILE
Satisfaction
"The chemistry is incredible. Every time we're together, it's a high. 10/10."
Alternatives
"I'm at a point where I'm meeting a lot of interesting people at work. 8/10."
Investment
"We've only been dating for 3 months. We live separately. 2/10."
Task: Predict the likelihood of persistence if a significant conflict (stressor) occurs. Justify using the model.
Critical Synthesis
While the Investment Model is a powerful predictor, modern critics argue it may be less effective in explaining "Decision-to-Leave" in Avoidant-Attached populations compared to Securely-Attached ones.
Research Question: How might "Quality of Alternatives" be psychologically inflated for an individual with an avoidant attachment style? How would this affect the commitment score (C)?

Seminar Discussion Hooks
1. The Sunk Cost Fallacy in Love
"Is the 'Investment' component of Rusbult's model a rational assessment of resources, or is it a psychological trap (the sunk cost fallacy)? Does the perception of investment change as the relationship degrades?"
— Target: Evolutionary vs. Cognitive Cognitive debate.
2. Digital Alternatives
"How has the advent of dating apps (Tinder/Hinge) altered the 'Quality of Alternatives' parameter? In a graduate seminar context, discuss whether the *perceived* availability of alternatives now chronically suppresses commitment scores in younger cohorts."
— Target: Modern sociotechnical impact on model validity.
Expert Context: Rusbult vs. Social Exchange
"The Investment Model is an extension of Social Exchange Theory (Thibaut & Kelley, 1959). While SET focuses on immediate rewards/costs and comparison levels (CL and CL-alt), Rusbult argued that these alone cannot explain why people stay during 'lean' times. The addition of **Investment** is the critical moderator that accounts for persistence during low-satisfaction periods."
Student Misconceptions
The "Happiness" Bias
Students often assume that low satisfaction (unhappiness) is the primary driver of dissolution. Remind them that satisfaction is the *weakest* predictor of persistence compared to the other two pillars in high-investment contexts.
Defining Alternatives
Clarify that "Alternatives" includes being alone. For some individuals, especially those with anxious attachment or low self-efficacy, the "Alternative" of being single is perceived as extremely low quality, thus artificially inflating commitment.

The Four Horsemen of the Apocalypse
1. Criticism
"You always..." / "What is wrong with you?"
Attacking the partner's character rather than a specific behavior.
2. Contempt
"I'm so much more mature than you."
The #1 predictor of divorce.
Eye-rolling, sarcasm, sneering. Asserting superiority.
3. Defensiveness
"It's not my fault! I only did it because..."
Self-protection through righteous indignation or playing the victim.
4. Stonewalling
(Silence / Looking away)
Withdrawing from interaction to avoid conflict. Shutting down.
Diffuse Physiological Arousal (DPA)
Flooding
The sensation of being overwhelmed by a partner's negativity. The nervous system enters "Fight-or-Flight" mode.
Heart rate exceeding 100 BPM
Shallow breathing
Cognitive shut-down
The Repair Attempt
"A secret weapon: Any statement or action that prevents negativity from escalating out of control."
In stable couples, repair attempts are accepted. In unstable couples, they are ignored or rejected.
The Magic Ratio
5
:
1
For every 1 negative interaction during conflict, stable couples have at least 5 positive interactions.
"It’s not the absence of conflict that matters, but the presence of positive affect during conflict."

Behavioral Synthesis
Identify the most prevalent negative affect and any attempted 'Repairs'. Were repairs accepted?
Predictive Logic
Based on the 5:1 ratio and the presence of the 'Horsemen', what is your prediction for this couple's long-term stability?
Clinical Note: Contempt is the only affect that actually correlates with physical illness (weakened immune system) in the partner. Observe facial asymmetry (sneer) closely.

Instructor Focus
Ensure students distinguish between Criticism (behavioral complaint gone wrong) and Contempt (position of moral superiority). Contempt is the most frequent coding error.
01
The "Thin Slice" Provocation
"How can 180 seconds of conversation determine the fate of a decades-long marriage? If we believe Gottman's accuracy, what does this suggest about the 'personality' of a relationship versus the personality of the individuals?"
Discussion target: Dynamic Systems Theory in Relationships.
02
Physiological Flooding vs. Cognitive Agency
"Gottman observes that when heart rates cross 100 BPM, the 'listening' part of the brain effectively shuts down. In a clinical setting, should the focus be on communication skills, or on biological regulation first?"
Discussion target: Somatic vs. Cognitive Interventions.
03
The Gender Narrative in Stonewalling
"85% of stonewallers in Gottman’s heterosexual lab samples are men. Is this an evolutionary trait (minimizing escalation), a socialized behavior, or a physiological difference in recovery time from flooding?"
Discussion target: Sociocultural vs. Biological gender differences.
Observer Calibration Tips
Contempt Detection
Look for the unilateral lip-corner pull (sneer) or mocking voice tone. It is distinct from anger by the presence of 'looking down' on the partner.
Repair Detection
Repairs can be subtle: a silly face, a touch on the arm, or saying "I'm sorry, I'm stressed." The coding isn't just the action, but the reception .
The Lab Debrief
"At the end of the coding session, ask students if they felt a physical reaction (empathy or stress) while watching the clips. Use this to pivot to the 'contagion' of affect in relationships and the clinician's own risk of vicarious trauma when working with high-conflict couples."
Cultural Maintenance Slides Global Psychology Seminar #04
Cultural Contexts
Deconstructing Western Models of Relationship Maintenance
Collectivism vs. Individualism
Construct Validity Focus
The WEIRD Problem
Most relationship research is conducted on samples that are Western, Educated, Industrialized, Rich, and Democratic.
Central Critique
Is "marital satisfaction" a universal goal, or is it a luxury construct of individualistic cultures?
Individualism
Marriage as a vehicle for personal self-actualization and romantic fulfillment.
Collectivism
Marriage as a vehicle for social stability, kinship ties, and generational continuity.
The Maintenance Paradox
"Love Marriages"
Intensity starts high and often shows a "decay curve" as passion habituates.
Satisfaction over time
"Arranged Marriages"
Intensity starts low/neutral and often shows an "accrual curve" through shared investment.
Satisfaction over time
The Validity Gap
01
Linguistic Equivalency
Does "Love" (English) capture the same neurobiological or social phenomena as "Amae" (Japanese) or "Yuanfen" (Chinese)?
02
Measurement Invariance
Standardized scales (e.g., DAS, CSI) often weigh "individual autonomy" highly. This penalizes collectivist maintenance strategies as "co-dependent" or "oppressive."
03
Ecological Validity
Is a high-conflict marriage a "failure" in a culture where divorce is non-viable, or is "peaceful coexistence" a more valid success metric?
"Is the pursuit of 'Happiness' in marriage actually a predictor of instability?"
Discuss the irony that cultures prioritizing individual happiness have the highest dissolution rates, while those prioritizing duty have the highest persistence.

Critical Synthesis: Construct Validity
Prompt 01: The Autonomy Trap
"If relationship maintenance in a collectivist culture relies on 'endurance' (Gaman) rather than 'happiness,' is it psychologically valid for Western researchers to label these relationships as 'unsuccessful' or 'distressed'?"
Prompt 02: Accrual vs. Erosion
"Evaluate the 'accrual' model of love often found in arranged marriages. How does the Investment Model (Lesson 1) need to be modified to account for relationships where investment *precedes* satisfaction?"
Note: Students should reference Fiske's Relational Models Theory when completing the 'Definition of Failure' section.

Culture & Validity Discussion Guide
Challenging the Hegemony of Western Relationship Science
Core Seminar Theme
"The export of Western psychology as a 'universal' science often functions as a form of cultural imperialism, pathologizing collectivist stability as co-dependence."
Discussion Objectives
Critique the construct validity of "Marital Satisfaction."
Analyze the "Arranged Marriage Paradox" (Satisfaction increasing over time).
Evaluate the role of the "Extended Family" as a maintenance mechanism.
The "Autonomy" Bias
"In the US, we view the 'we' as a choice made by two 'I's. In many collectivist cultures, the 'I' is inseparable from the 'we.' If individual autonomy is not the goal, how must we redesign our clinical intake forms for these couples?"
Target: Clinical practice adaptation.
The Duty vs. Desire Dilemma
"Is a relationship sustained by duty 'worse' than one sustained by desire? Or is duty a more stable, less volatile maintenance mechanism for long-term societal health?"
Target: Philosophical foundations of maintenance.
Essential Literature & Construct Validity
The WEIRD Bias
Henrich, Heine, & Norenzayan (2010). This is the seminal paper on the unrepresentative nature of psychology's participant pool. Use this to ground the critique of "Universal" findings.
The Arranged Marriage Curve
Gupta & Singh (1982). A classic study showing that love in arranged marriages often starts low but surpasses love-match satisfaction after 5-10 years.
Facilitation Alert
"Students often conflate 'Arranged Marriage' with 'Forced Marriage.' Be vigilant in correcting this. An arranged marriage in a modern graduate-level context often involves veto power and high agency. Focusing on the 'forced' narrative prevents a deep dive into the *mechanics* of how love can be built by design rather than by accident."
Dissolution Psychology Slides Capstone Seminar #05
Dissolution
Self-Expansion, Recovery, and Post-Relationship Growth
The "Me" after "We"
Post-Traumatic Growth
Self-Expansion Loss
Aron’s model posits that relationships allow us to "expand" our self-concept by incorporating the partner’s identity, resources, and perspectives.
The Breakup Void
Dissolution is not just the loss of a person; it is a contraction of the self . We literally lose parts of who we were.
THE SELF
PARTNER
Neural Withdrawal
Love as Addiction
Fisher (2010) fMRI studies show that looking at photos of an ex-partner activates the ventral tegmental area and nucleus accumbens .
> Brain activity mirrors cocaine withdrawal.
Physical Pain
Social rejection activates the same neural pathways as physical pain (somatosensory cortex).
"Taking Tylenol (Acetaminophen) has been shown in some studies to reduce the 'pain' of social exclusion."
The Recovery Arc
Identity Re-discovery
Engaging in novel activities that were previously restricted by the relationship to "re-expand" the self.
Personal Strength
A renewed sense of self-efficacy: "If I survived that, I can survive anything."
New Perspectives
Shifting from "The Ending" to "The Beginning" of a new developmental phase.
Intervention Design

Capstone: Post-Relationship Identity Recovery
Project ID: DIS-CAP-05
The Challenge
"You are tasked with designing a hypothetical 4-week clinical intervention for individuals experiencing 'Complicated Grief' following a high-investment relationship dissolution. Your proposal must leverage Self-Expansion Theory and Neural Regulation strategies."
01
Phase I: The Neuro-Somatic Detox (Week 1)
Based on Fisher's "Love as Addiction" research, what specific behavioral interventions would you mandate to manage the 'dopaminergic withdrawal' of a fresh breakup?
02
Phase II: Self-Concept Re-Expansion (Weeks 2-3)
Using Aron’s Self-Expansion Model, design one 'Novel Activity' exercise aimed at decoupling the client’s identity from the former partner’s resources and perspectives.
03
Phase III: Narrative Integration (Week 4)
How will you facilitate the shift from 'Victim Narrative' to 'Growth Narrative'? What qualitative metrics would indicate a successful move toward Post-Traumatic Growth?
Submission Requirement
Proposals must include at least three citations from the semester reading list. Ensure you address the "Social Contagion" of breakups—how will the client manage the loss of the shared social network as part of their recovery?

Clarity & Academic Rigor 10%
Criteria Exemplary (90-100) Proficient (75-89) Model Application Deeply integrates the Investment Model and Self-Expansion Theory; uses specific data to justify interventions. Refers to models accurately but lacks depth in connecting research data to specific clinical actions. Neuro-Somatic Awareness Interventions specifically address DPA (Flooding) and neural withdrawal mechanisms (Fisher/Gottman). Mentions physiological aspects but interventions are primarily cognitive/conversational. Cultural Competency Acknowledges the Western bias of the models; proposes adaptations for non-WEIRD populations. Mentions cultural context but the intervention remains largely Western-centric.
Final Seminar Debrief Prompts
The Persistence vs. Dissolution Ethic
"As psychologists, is our primary duty to help couples maintain their relationships (persistence) or to help individuals maximize their growth (dissolution)? How does the Investment Model complicate this ethical choice?"
Future Research Frontiers
"Where is the 'blind spot' in relationship science? Based on our 5 lessons, what is the one variable we haven't discussed that might be the next major predictor of relationship stability in the 2030s?"
Closing the Loop
"Encourage students to reflect on their own 'Self-Expansion' over the course of this unit. By deconstructing the mechanics of love, they have expanded their professional identity to include rigorous scientific skepticism alongside clinical empathy. This is the hallmark of a graduate-level practitioner."
