2. Communication Protocol: Conflict Dimension
John Gottman's Relationship Stability Research (1994)
Theoretical Background
Theoretical Origins & Development: The Conflict dimension is grounded in Professor John Gottman's relationship stability research at the University of Washington. Since the 1970s, Gottman established the "Love Lab," using physiological monitoring, behavioral coding, and longitudinal tracking to study interaction patterns of over 3,000 couples. His team developed the Specific Affect Coding System (SPAFF), which predicts divorce with 94% accuracy. These findings, published in top journals including the Journal of Marriage and Family, established the empirical foundation of modern relationship science.
Core Findings: Gottman's research overturned the traditional view that "conflict harms relationships." He found that the presence of conflict isn't the issue—how conflict is handled is the key variable predicting relationship outcomes. He identified three stable conflict styles: Volatile, Validating, and Avoiding; plus one dysfunctional type: Hostile. The common characteristic of the three stable types is maintaining a positive-to-negative interaction ratio of approximately 5:1.
RSTI's Simplification Logic: Considering test usability and discriminant validity, RSTI condenses Gottman's classification into two core styles—Expressive (Volatile) and Regulated (Calm)—focusing on emotional expression intensity and processing timing preferences in conflict situations.
Volatile (V)
Expressive / Directly Externalized
Expressive individuals tend to immediately externalize emotional reactions in conflict situations, adopting active discussion strategies. Characteristics include: rapid and intense emotional responses, preference for immediate problem-addressing rather than postponement, and high engagement and passion during arguments. Expressive types believe direct communication quickly clarifies issues, releases tension, and enables rapid restoration of emotional connection post-conflict. Gottman's research indicates that expressive couples have greater positive-negative interaction fluctuation, but remain equally stable as long as sufficient positive interaction ratios are maintained. This type is more prevalent in Latin American and Mediterranean cultures.
Calm (C)
Regulated / Rationally Processed
Regulated individuals tend to suppress immediate emotional reactions in conflict situations, adopting delayed processing or rational analysis strategies. Characteristics include: needing solitary time to process emotions, preferring discussion after emotional recovery, and valuing logical discourse over emotional venting. Regulated types believe calm minds make rational decisions, avoiding hurtful language during heightened emotions. Gottman's research shows overlap between regulated and avoidant types, but regulated types don't completely avoid conflict—they choose to address it in controlled settings. This type is more common in East Asian and Nordic cultures.
Key Insights
- 1
Style Matching Research: Gottman found that partners with the same conflict style (e.g., two expressive types or two regulated types) are typically more stable than mixed pairings, as both share consensus on "normal conflict handling."
- 2
Demand-Withdraw Cycle: When expressive and regulated types pair, the most common dysfunctional pattern is the "Demand-Withdraw Pattern": expressive types feel ignored and intensify pursuit, regulated types feel pressured and withdraw further, creating a negative spiral. Breaking this cycle requires both parties to understand that the other's processing style is not hostile.

The Four Horsemen: Gottman identified that truly destructive elements are not conflict styles themselves, but four harmful communication patterns: Criticism, Contempt, Defensiveness, and Stonewalling. Regardless of conflict style, when these four behaviors appear, relationships face significant risk.
