Relationships and the trauma-aware register — C2

In the past fifteen years, US relational discourse has been reshaped by clinical-trauma vocabulary that was once specialist. Attachment styles moved from John Bowlby and Mary Ainsworth’s developmental research into Sue Johnson’s couples therapy and then into Instagram. Parts work — Richard Schwartz’s Internal Family Systems (IFS) — went from a small somatic-psychotherapy niche to the New York Times’s magazine pages. Polyvagal theory (Stephen Porges) gave the broader public a vocabulary for nervous-system regulation, co-regulation, fight-flight-freeze-fawn, and the window of tolerance. Complex PTSD (C-PTSD), pioneered by Judith Herman in Trauma and Recovery (1992), is now in the ICD-11 (though not in the DSM). Bessel van der Kolk’s The Body Keeps the Score (2014) became an unlikely long-running bestseller and seeded a wider cultural literacy in somatic trauma.

This vocabulary is contested. Much of it is clinically useful, but it has also been popularized — and over-popularized — into pseudo-diagnostic identity claims (“I’m avoidant, you’re anxious; we’re doomed”). A C2 reader handles both the serious clinical register (van der Kolk, Schwartz, Porges, Herman, Maté, Gabor Maté, Pat Ogden) and the social-media vernacular (“trauma response”, “attachment wound”, “regulating my nervous system”) with calibration. Some terms carry real research weight; others are colloquial extensions that working clinicians use with caution.

This lesson maps the working vocabulary of 2026 US relational discourse — from the attachment quadrants to nervous-system literacy to the somatic-therapy modalities now widely practiced in the US.

Attachment theory — the four-style framework

Attachment theory began with John Bowlby and Mary Ainsworth’s developmental research on infant-caregiver bonding. Adult attachment styles (Hazan & Shaver, Mary Main, Mikulincer & Shaver) extended the framework to romantic relationships.

The four adult attachment styles

• secure attachment — comfortable with intimacy and autonomy; can give and receive support; tolerates relational stress.
• anxious attachment / anxious-preoccupied — preoccupied with relational availability; hypervigilant to abandonment cues; protest behavior when distressed.
• avoidant attachment / dismissive-avoidant — discomfort with intimacy; self-reliant to a defensive degree; minimizes attachment needs.
• disorganized attachment / fearful-avoidant — both wants and fears intimacy; often a marker of early relational trauma; the “approach-avoid” pattern.

Working terms:

• the secure base — caregiver as platform from which to explore.
• the safe haven — caregiver as refuge in distress.
• internal working models — Bowlby’s term for mental representations of self-and-other.
• the strange situation — Ainsworth’s classic experimental paradigm (infant-caregiver-stranger sequence).
• proximity-seeking — moving toward attachment figure under stress.
• protest behavior — anxious attempts to re-engage a withdrawing partner.
• deactivating strategies — avoidant suppression of attachment needs.
• hyperactivating strategies — anxious amplification of distress.
• earned secure — moving from insecure to secure in adulthood (often through a corrective relationship or therapy).
• attachment injury — relational rupture that damages trust.
• rupture and repair — the cycle that builds (or erodes) attachment security.

“Adult attachment research has largely converged on a continuum view: anxiety and avoidance as two dimensions, with categorical labels (anxious, avoidant) as useful shorthand but not natural kinds. The four-style infographic culture has flattened the science.” — The Atlantic, 2024.

Parts work and Internal Family Systems (IFS)

Richard Schwartz’s IFS framework, developed in the 1980s and now massively popular in US therapeutic practice.

• parts work — psychotherapy that treats the psyche as composed of distinct “parts” (sub-personalities, internal voices).
• IFS (Internal Family Systems) — the most influential parts-work modality.
• the Self (capital S in IFS) — the calm, curious, compassionate core; the leadership the system needs.
• parts — sub-personalities, often with distinct ages, voices, agendas.
• exiles — wounded young parts holding pain.
• managers — proactive protectors that organize life to prevent exiles from being triggered.
• firefighters — reactive protectors that activate when exiles’ pain breaks through (often via substances, food, sex, rage, dissociation).
• the 8 C’s of Self (Schwartz) — calm, curiosity, clarity, compassion, confidence, creativity, courage, connectedness.
• unblending — separating Self from a part that has “taken over” consciousness.
• the part’s positive intent — IFS assumption that every part is trying to help.
• the burden — the painful belief or emotion a part carries.
• unburdening — IFS’s term for the release of the burden in therapy.
• internal alliance — Self collaborating with parts.

Related parts-vocabulary used outside IFS proper:

• the inner child — a more popularized parts-framing.
• the inner critic — a critical-internalized-voice part.
• the protector — generally any defensive part.
• the wounded part — generic for younger pain-carrying part.

“What IFS gets right — and what makes it endure even among clinicians skeptical of its metaphysics — is that human beings really do experience themselves as multiple: the part that wants the cigarette and the part that wants to quit are not arguing about a single underlying preference. They are different parts with different agendas, and treating the inner conflict as a negotiation rather than a contradiction often works.” — NYT Magazine, 2023.

Polyvagal theory and the autonomic-nervous-system vocabulary

Stephen Porges’s polyvagal theory has become the dominant framework in popularized trauma therapy.

• polyvagal theory — Porges’s account of vagus-nerve organization and its role in autonomic regulation.
• the autonomic nervous system (ANS) — controls involuntary functions; sympathetic and parasympathetic branches.
• the sympathetic nervous system — mobilizing, fight-or-flight.
• the parasympathetic nervous system — rest-and-digest.
• the vagus nerve — the tenth cranial nerve, central to parasympathetic regulation.
• ventral vagal — the newer (mammalian) branch; supports social engagement, calm-and-connected states.
• dorsal vagal — the older branch; immobilization, freeze, shutdown.
• the polyvagal ladder — popularization: ventral vagal (safe) ↑, sympathetic (mobilized) middle, dorsal vagal (shutdown) ↓.
• neuroception (Porges) — subconscious detection of safety/threat.
• co-regulation — using another person’s nervous system to regulate one’s own.
• self-regulation — managing one’s own state.
• dysregulation — out-of-window state; either hyperaroused or hypoaroused.
• the window of tolerance (Dan Siegel) — the optimal arousal zone for processing experience.
• hyperarousal — anxiety, agitation, hypervigilance, panic.
• hypoarousal — numbness, dissociation, shutdown, collapse.
• the four F’s — fight, flight, freeze, fawn (Walker’s addition).
• the fawn response — Pete Walker’s term for trauma-driven appeasement and people-pleasing.
• felt sense (Gendlin) — bodily-felt awareness of an experience; pre-conceptual.
• interoceptive awareness — perception of internal bodily signals.
• HRV (heart rate variability) — proxy measure for vagal tone; higher HRV correlates with resilience.

Complex PTSD (C-PTSD) — the diagnostic frame

Judith Herman’s 1992 Trauma and Recovery and the ICD-11 codification.

• PTSD (Post-Traumatic Stress Disorder) — DSM/ICD diagnosis; classically tied to single-event trauma.
• C-PTSD (Complex PTSD) — Herman’s framework for prolonged, repeated, interpersonal trauma (childhood abuse, captivity, long-term domestic violence); recognized in ICD-11 (2018) but not in DSM-5-TR.
• the symptom clusters of PTSD: intrusion (flashbacks, nightmares), avoidance, negative alterations in mood/cognition, hyperarousal.
• the additional clusters in C-PTSD: disturbances in self-organization (DSO), affect dysregulation, negative self-concept, interpersonal difficulties.
• single-event trauma vs developmental trauma vs relational trauma.
• little-t trauma vs big-T Trauma — informal distinction; the former for less acute but cumulative, the latter for classically traumatic events. Many trauma clinicians now reject the distinction as flattening.
• adverse childhood experiences (ACEs) — Felitti & Anda’s framework; 10-item questionnaire of childhood adversity types; correlates with adult health outcomes.
• developmental trauma disorder (DTD) — van der Kolk’s proposed (and rejected by DSM) diagnostic category.
• trauma response — colloquial; in clinical use refers to specific behavioral/physiological patterns activated by reminders.
• trigger / triggered — clinical term meaning stimulus that activates a trauma response; widely overused and trivialized in popular discourse.
• flashback — vivid intrusive re-experiencing.
• emotional flashback — Pete Walker’s term for affective re-experiencing without explicit memory.
• dissociation — disruption in integration of consciousness, memory, identity, perception.
• the dissociative spectrum — from mild absorption to DID (Dissociative Identity Disorder).
• depersonalization — feeling unreal or detached from self.
• derealization — feeling the world is unreal.
• flashbacks vs emotional flashbacks vs somatic flashbacks — different intrusion modes.

“Herman’s Trauma and Recovery did for complex trauma what DSM-III had done for single-event PTSD: it produced a vocabulary that allowed survivors and clinicians to recognize a previously unnamed clinical picture. Three decades later, complex PTSD remains absent from the DSM and present in nearly every actual clinical practice.” — NYRB, 2022.

Somatic therapies — the modalities

The modalities now widely practiced in US trauma therapy.

• somatic experiencing (SE) — Peter Levine’s body-based approach focused on completing thwarted survival responses.
• sensorimotor psychotherapy (Pat Ogden) — combines somatic awareness with traditional psychotherapy.
• EMDR (Eye Movement Desensitization and Reprocessing) — Francine Shapiro’s bilateral-stimulation protocol; despite skeptical mechanistic evidence, robust outcome data for PTSD.
• brainspotting (David Grand) — eye-position-based variant.
• IFS (Internal Family Systems) — Schwartz’s parts-work (covered above).
• AEDP (Accelerated Experiential Dynamic Psychotherapy, Diana Fosha) — emotion-focused dynamic therapy.
• Hakomi — Ron Kurtz’s mindfulness-based body-centered therapy.
• NARM (NeuroAffective Relational Model, Laurence Heller) — developmental trauma approach.
• Internal Family Systems-informed — adjective for clinicians integrating parts work without full IFS training.
• trauma-informed — broader descriptor for practices recognizing trauma’s effects.
• trauma-sensitive — softer version.
• bottom-up vs top-down therapy — body-first vs cognition-first approaches; both are needed.
• pendulation (Levine) — alternating between activation and resourcing in SE.
• titration — small-dose exposure to traumatic material.
• resourcing — building safety and capacity before processing trauma.
• the felt sense — Gendlin’s term (covered above).
• the body keeps the score — van der Kolk’s title, now a meme; the somatic-memory hypothesis.

Couples therapy and relational-process vocabulary

• EFT (Emotionally Focused Therapy, Sue Johnson) — attachment-based couples therapy.
• the cycle (EFT) — the negative interaction pattern partners get stuck in.
• demand-withdraw pattern — one partner pursues, the other withdraws.
• pursuer/distancer dynamic — same.
• the four horsemen (Gottman) — criticism, contempt, defensiveness, stonewalling; predictors of divorce.
• stonewalling — emotional shutdown during conflict.
• flooding — autonomic overwhelm during conflict.
• contempt — the most predictive of the four (per Gottman research); communicates superiority.
• bids for connection (Gottman) — small attempts to engage; partner can turn toward, turn away, turn against.
• turning toward vs turning away vs turning against — Gottman’s response taxonomy.
• the love map (Gottman) — knowledge of partner’s inner world.
• the magic ratio (5:1 positive to negative interactions) — Gottman’s correlational finding.
• repair attempt — actions to de-escalate during conflict.
• rupture and repair — the broader pattern.
• attunement — present, responsive attention to partner’s state.
• misattunement — failures to read partner’s state correctly.
• bid — Gottman’s term for a small connection request.

“Gottman’s lab found that the difference between marriages that lasted and those that didn’t was not whether couples fought — every couple fights — but whether the fighting included contempt. Contempt corrodes; criticism wounds; defensiveness deflects; stonewalling kills. The ‘four horsemen’ framing has held up across thirty years of replication.” — Atlantic, 2023.

Boundaries, consent, and the relational-ethics register

• boundaries — clinical term for limits one sets to protect one’s wellbeing.
• healthy boundaries vs rigid boundaries vs enmeshed/diffuse boundaries.
• the porous boundary — overly permeable; common in anxious attachment.
• the rigid boundary — overly walled; common in avoidant attachment.
• to set a boundary / to hold a boundary / to enforce a boundary — the verb collocations.
• boundary violation — crossing of a limit.
• enmeshment — boundaries collapsed; one identity bleeding into another.
• codependency — a popularized (and now somewhat dated) term for over-functioning in a partner’s life at one’s own expense.
• interdependence — the healthier version codependency literature aimed at.
• consent — explicit agreement to participate.
• affirmative consent — yes means yes (vs absence of no).
• ongoing consent — consent is continuous, not point-in-time.
• the consent culture — the broader cultural project around consent.
• enthusiastic consent — the rhetorical bar.
• conditional consent — consent given on specific terms.
• withdrawn consent — withdrawal mid-act.
• coercive control (Evan Stark) — pattern of coercive intimate-partner behavior beyond physical violence.
• gaslighting — manipulation that makes the victim doubt their reality (term from the 1944 film); the most overused trauma-vocabulary import in the 2020s.
• DARVO (Deny, Attack, Reverse Victim and Offender) — Jennifer Freyd’s term for a specific gaslighting pattern.

Non-monogamy and relationship-structure vocabulary

• monogamy — sexually and romantically exclusive pairing.
• serial monogamy — sequential exclusive relationships.
• non-monogamy — umbrella for non-exclusive arrangements.

Common Russian-speaker mistakes

1. *Boyfriend* / *girlfriend* for adult partners only in early dating. Russians sometimes find these terms juvenile (because парень/девушка feel young in Russian). In AmE, boyfriend and girlfriend are used at any age — 60-year-olds say my girlfriend. Partner is the higher-register gender-neutral option, popular in queer and increasingly hetero contexts. Avoiding boyfriend by saying my young man (Russian-influenced; Victorian) is dated and odd.
2. *Marry with* for marry. Calque of жениться с. AmE: marry takes a direct object, no preposition. She married John (not with John). The preposition to appears with engaged: engaged to John; not with marry. Russians overproduce with here.
3. *Sympathy* for liking someone. Catastrophic false friend with симпатия. Sympathy in English = feeling sorry for someone in distress (I have sympathy for the victims). For Russian симпатия (= attraction, fondness), AmE uses a crush (romantic, often early), fondness, affection, affinity, liking, chemistry. I have sympathy for her implies pity, not attraction.
4. *To meet* for to date. Calque of встречаться. To meet someone = either first encounter (we met at a party) or appointment (let’s meet for coffee). To date = romantic involvement (we’re dating). Russians often say we’re meeting meaning we’re dating — this is wrong; native is we’re seeing each other or we’re dating.
5. *Pretty* as default for women in adult/professional contexts. Russian красивая is general. AmE pretty is mild praise (often for younger or for a momentary look); beautiful is stronger; gorgeous stronger still; stunning intense. For adult women in professional contexts, pretty sounds slightly diminishing — beautiful, striking, radiant, elegant avoid the diminutive tone.
6. *To divorce with* for to divorce. Calque of развестись с. AmE: divorce takes a direct object without preposition for the act (she divorced him); the resulting state takes from: divorced from her first husband. To get a divorce is the most common phrasing. I divorced with my husband is wrong; I divorced my husband or I got divorced is right.
7. *Family* for extended kin. Russian семья often includes parents, grandparents, siblings. In AmE, family can mean either the nuclear family (spouse + children) or the extended family depending on context; for the latter, AmE often specifies: my extended family, my relatives, my folks. My family is coming for Christmas could mean five or fifty; native speakers clarify if needed. The word folks is friendly AmE for one’s family (how are your folks?).
