关系如何塑造你的大脑 | Dr. Allan Schore

摘要

UCLA临床精神分析师兼神经科学家Dr. Allan Schore阐释了生命最初24个月如何通过与主要照料者的依恋互动来塑造大脑右半球。这些早期情绪调节模式成为所有成人关系的基础，并可通过模拟母婴互动的治疗过程加以改变。

核心要点

• 90–95%的行为是无意识的，由右脑处理过程支配，持续运作于意识觉知之下
• 右半球主导大脑发育，从妊娠最后三个月持续至2–3岁，这意味着所有早期依恋从根本上都是右脑过程
• 依恋风格（安全型、焦虑型、回避型、混乱型）由主要照料者同步并调节婴儿情绪唤醒状态的能力塑造
• 婴儿期形成的右脑回路在成年后直接被复用于浪漫关系、社交关系和职业关系
• 安全依恋需要两种能力：心理生理协调（与婴儿情绪状态同步）和修复失调（断开连接后重新建立联结）
• 有效的治疗通过与早期养育相同的右脑对右脑沟通发挥作用——治疗关系本身才是主要的改变机制
• 互动调节（与他人共同调节）比自我调节更为根本；过度依赖自我调节是回避型依恋模式的根源
• 情感高峰时刻——真实情感同步的短暂窗口（50–60秒）——是持久神经变化真正发生的时机
• 右脑使用广域注意（均匀悬浮的注意力），左脑使用狭窄的聚焦注意——在两者之间切换对于深度连接至关重要
• 正性情绪（喜悦、兴奋）与调节负性状态同等重要，却在依恋理论和治疗实践中被系统性地低估

详细笔记

左脑与右脑：基本架构

• 右半球处理情绪、内隐沟通、主观性、直觉、意象和自主神经调节
• 左半球处理语言、逻辑、外显/意识内容和客观推理
• 右半球从妊娠最后三个月至2–3岁进入主要的神经可塑性生长爆发期；左半球的生长爆发期始于第二年末至第三年
• 这一顺序解释了为何所有早期依恋动态都是非语言的、内隐的——彼时语言尚未存在
• 右脑主导周期在整个生命历程中反复出现，包括青春期，此时另一个生长爆发期以右半球阶段开始，随后向左转移

依恋的神经生物学

• 依恋被定义为互动调节——具体而言，是主要照料者对婴儿边缘系统和自主神经系统的调节
• 母亲通过面部、声音和手势调节婴儿的状态：解读面部表情、声音韵律以及触觉/手势信号
• 照料者逐时追踪婴儿的唤醒状态，与这些状态同步，然后进行上调或下调：
  • 下调：软化声调、平静面部表情以降低交感神经过度激活
  • 上调：生动的面部表情、上扬的声调，使婴儿进入积极兴奋的状态
• 涉及的关键神经化学物质：多巴胺（奖励/正性状态）、去甲肾上腺素/肾上腺素（唤醒）、皮质醇（应激反应）
• 右眶额皮质是右半球的最高执行调节器；它与杏仁核、脑岛和扣带回形成连接——治疗改变在神经层面就定位于此

四种依恋风格

风格	调节模式	成人表现
安全型	自我调节与互动调节均可用；整合正性与负性情绪	灵活、有韧性，能耐受亲密与自主
回避型/疏离型	主要依赖自我调节；去激活依恋系统	应激时情感疏离；声音趋于平淡；理智化
焦虑型/矛盾型	主要寻求互动调节；无法自我安抚	过度激活依恋系统；对被遗弃的信号高度敏感
混乱型（D型）	两种策略均无法使用；以解离关闭依恋系统	与创伤后应激障碍、边缘型人格障碍相关

心理生理协调与修复

• 心理生理协调：照料者不仅调节婴儿的心理体验，也调节其生理状态（自主神经系统）
• 失调不可避免，且本身并不造成伤害——关键在于修复
• “足够好”的照料者会失调，然后重新同步，教会婴儿破裂是可以承受的，联结可以恢复
• 持续无法修复 → 形成不安全型依恋

子宫内发育

• 大脑侧化从胎儿期即开始；早期记忆甚至在出生前就储存于右侧杏仁核
• 右脑岛和中央杏仁核在子宫内开始发育
• 自主神经调节跨越胎盘开始——母亲与胎儿在产前即同步神经系统
• 母体皮质醇穿越胎盘屏障：妊娠期慢性母体应激可在右侧杏仁核关键期内损害其最佳发育

父亲的角色

• 父亲通常在第二年成为主要依恋人物，此时左半球开始其生长爆发期
• 父亲的玩耍往往更具唤醒性和身体刺激性（粗犷玩耍），教导孩子耐受更高的交感神经唤醒状态并培养冒险精神
• Dr. Schore认为，母亲主要塑造第一年婴儿的右脑；父亲主要塑造第二至三年婴儿的左脑
• 在单亲家庭中，一位照料者可以在整个发育历程中提供这两方面的功能

治疗如何修复早期依恋

• 有效的治疗通过治疗师与患者之间的右脑对右脑沟通，重现母婴互动动态
• 治疗师必须放开自我——从左脑分析性倾听转向右脑广域注意（弗洛伊德所说的”均匀悬浮的注意力”）
• 治疗过程映射养育过程：
  1. 与患者的情绪/自主神经状态同步
  2. 追踪唤醒的高潮与低潮
  3. 通过声调、面部表情和手势进行内隐调节
  4. 共同创造情感高峰时刻——真实情感同步的短暂窗口，在此神经变化成为可能
• 治疗关系是改变的主要机制——而非解释或认知洞察
• 改善表现为右眶额皮质与杏仁核/脑岛/扣带回之间形成新的连接

两种注意类型

• 狭窄注意（左脑）：顺序性的、逻辑性的、逐字追踪
• 广域注意（右脑）：同时觉察外部情绪线索以及内部身体状态（通过右脑岛）
• 切换至广域注意会抑制狭窄注意——两者相互竞争；无法同时完全占据两种模式
• 有意识地扩展视野、放松分析性专注，有助于转换进入右脑模式

人际同步与右侧颞顶联合区

• **右侧颞顶联合区（rTPJ）**将面部、声音韵律和手势整合为情感沟通的统一信号
• 在真实的共情连接中，一方的rTPJ与另一方的rTPJ同步——已由超扫描神经影像学研究（fNIRS、EEG）证实
• 这种右脑对右脑的同步是共情的神经学基底，具有关系性——需要两个人的参与
• 关系无意识持续与另一个关系无意识沟通；无意识并非单纯内心的，而是从根本上具有人际性

正性情绪与调节

• 依恋理论历来过于强调负性状态的下调；正性状态（喜悦、兴奋、热情）的上调同等重要
• 两种形式的爱（D.W. Winnicott）：平静的爱（副交感

How Relationships Shape Your Brain | Dr. Allan Schore

Summary

Dr. Allan Schore, a clinical psychoanalyst and neuroscientist at UCLA, explains how the first 24 months of life shape the brain’s right hemisphere through attachment interactions with primary caregivers. These early patterns of emotional regulation become the foundation for all adult relationships and can be modified through therapeutic processes that mirror the original mother-infant dynamic.

---

Key Takeaways

• 90–95% of behavior is unconscious, governed by right brain processing that operates continuously beneath conscious awareness
• The right hemisphere dominates brain development from the last trimester of pregnancy through age 2–3, meaning all early attachment is fundamentally a right-brain process
• Attachment styles (secure, anxious, avoidant, disorganized) are shaped by how well a primary caregiver synchronized and regulated the infant’s emotional arousal states
• The same right-brain circuits formed in infancy are directly repurposed for adult romantic, social, and professional relationships
• Secure attachment requires two skills: psychobiological attunement (synchronizing with the infant’s emotional state) and repair of misattunement (re-connecting after disconnection)
• Effective therapy works through the same right-brain-to-right-brain communication as early caregiving — the therapeutic relationship itself is the primary change mechanism
• Interactive regulation (co-regulating with another person) is more foundational than auto-regulation; over-reliance on auto-regulation underlies avoidant attachment patterns
• Heightened affective moments — brief windows (50–60 seconds) of genuine emotional synchrony — are when lasting neurological change actually occurs
• The right brain uses wide-ranging attention (evenly suspended attention), while the left brain uses narrow, focused attention — switching between them is critical for deep connection
• Positive emotion (joy, excitement) is equally important to regulating negative states and is systematically underemphasized in both attachment theory and therapy

Detailed Notes

Right Brain vs. Left Brain: Basic Architecture

• The right hemisphere processes emotion, implicit communication, subjectivity, intuition, imagery, and autonomic regulation
• The left hemisphere processes language, logic, explicit/conscious content, and objective reasoning
• The right hemisphere enters its major neuroplasticity growth spurt from the last trimester of pregnancy through age 2–3; the left hemisphere’s growth spurt begins at the end of year two into year three
• This sequence explains why all early attachment dynamics are non-verbal and implicit — language simply doesn’t exist yet
• Right-brain dominance cycles recur across the lifespan, including during adolescence, when another growth spurt begins with a right-hemisphere phase before shifting left

The Neurobiology of Attachment

• Attachment is defined as interactive regulation — specifically, the regulation of the infant’s limbic system and autonomic nervous system by the primary caregiver
• The mother regulates the baby’s states through face, voice, and gesture: reading facial expressions, vocal prosody, and tactile/gestural signals
• The caregiver tracks the baby’s arousal moment-to-moment, synchronizes with those states, and then up- or down-regulates them:
  • Down-regulation: softening voice tone, quieting facial expression to reduce sympathetic hyperarousal
  • Up-regulation: animated face, rising vocal tone to bring baby into positive excited states
• Key neurochemicals involved: dopamine (reward/positive states), noradrenaline/adrenaline (arousal), cortisol (stress response)
• The right orbital frontal cortex is the highest executive regulator of the right hemisphere; it forms connections with the amygdala, insula, and cingulate — this is where therapeutic change is neurologically localized

The Four Attachment Styles

Style	Regulatory Pattern	Adult Expression
Secure	Both auto- and interactive regulation available; integrates positive and negative emotion	Flexible, resilient, tolerates closeness and autonomy
Avoidant/Dismissive	Primarily auto-regulates; deactivates attachment system	Emotionally distant under stress; voice flattens; intellectualizes
Anxious/Ambivalent	Primarily seeks interactive regulation; cannot self-soothe	Hyperactivates attachment; highly sensitive to cues of abandonment
Disorganized (Type D)	Cannot use either strategy; uses dissociation to shut down attachment system	Associated with PTSD, borderline personality disorder

Psychobiological Attunement and Repair

• Psychobiological attunement: the caregiver regulates not only the infant’s psychological experience but also its physiological state (autonomic nervous system)
• Misattunement is inevitable and not inherently damaging — what matters is the repair
• A “good enough” caregiver mis-attunes and then re-synchronizes, teaching the infant that rupture is survivable and connection can be restored
• Failure to repair consistently → insecure attachment formation

In Utero Development

• Lateralization begins in the fetus; early memories are stored in the right amygdala even before birth
• The right insula and central amygdala begin developing in utero
• Autonomic regulation begins across the placenta — mother and fetus synchronize nervous systems prenatally
• Maternal cortisol crosses the placental barrier: chronic maternal stress during pregnancy can impair optimal development of the right amygdala during its critical period

Role of the Father

• Fathers typically become a primary attachment figure in year two, as the left hemisphere begins its growth spurt
• Father’s play tends to be more arousing and physically stimulating (rough-and-tumble play), teaching tolerance of higher sympathetic arousal states and risk-taking
• Dr. Schore proposes the mother primarily shapes the baby’s right brain in year one; the father primarily shapes the baby’s left brain in year two–three
• In single-parent households, one caregiver can provide both functions across developmental time

How Therapy Repairs Early Attachment

• Effective therapy recreates the mother-infant dynamic through right-brain-to-right-brain communication between therapist and patient
• The therapist must surrender — shifting out of left-brain analytical listening into right-brain, wide-ranging attention (Freud’s “evenly suspended attention”)
• Therapeutic process mirrors caregiving:
  1. Synchronize with the patient’s emotional/autonomic state
  2. Track crescendos and decrescendos of arousal
  3. Implicitly regulate through voice tone, facial expression, and gesture
  4. Co-create heightened affective moments — brief windows of genuine emotional synchrony where neurological change becomes possible
• The therapeutic relationship is the primary mechanism of change — not interpretation or cognitive insight
• Improvements manifest as new connections between the right orbital frontal cortex and the amygdala/insula/cingulate

Two Types of Attention

• Narrow attention (left brain): sequential, logical, word-by-word tracking
• Wide-ranging attention (right brain): simultaneous awareness of external emotional cues AND internal bodily states (via the right insula)
• Shifting to wide-ranging attention suppresses narrow attention — the two compete; you cannot fully occupy both simultaneously
• Intentionally widening gaze and relaxing analytical focus facilitates the shift into right-brain mode

Interpersonal Synchrony and the Right Temporal Parietal Junction

• The right temporal parietal junction (rTPJ) integrates face, vocal prosody, and gesture into a unified signal for emotional communication
• During genuine empathic connection, the rTPJ of one person synchronizes with the rTPJ of the other — confirmed by hyperscanning neuroimaging studies (fNIRS, EEG)
• This right-brain-to-right-brain synchrony is the neurological substrate of empathy and is relational — it requires two people
• The relational unconscious communicates continuously with another relational unconscious; the unconscious is not solely intrapsychic but fundamentally interpersonal

Positive Emotion and Regulation

• Attachment theory has historically over-emphasized downregulation of negative states; upregulation of positive states (joy, excitement, enthusiasm) is equally critical
• Two forms of love (D.W. Winnicott): quiet love (parasympathetic
