Securely attachedinfants can freely express distress, receive comforting care, and return to exploration. This teaches them that close others will be available and responsive when needed (Ainsworth, 1979).
Insecurely attached infants, who receive less sensitive care, develop alternative strategies for regulating distress that persist into adulthood (Main, 1996; Mikulincer & Shaver, 2007).
Deactivating strategies: suppressing/ minimizing negative emotions to limit the hurt and disappointment that is expected to occur when depending on close others.
Key Points
Rationale
No prior study has directly tested whether observed infant attachment security versus insecurity predicts specific emotion regulation strategies decades later when managing distress in adult romantic relationships.
This is a significant gap because attachment theory proposes that early caregiving shapes prototype strategies for regulating attachment-related emotions with close others throughout life.
This allowed a direct test of whether early attachment security/insecurity predicts attachment-relevantemotion regulation strategiesmuch later in development – an essential premise of attachment theory that has substantial implications for socioemotional functioning, but has not yet been empirically demonstrated over such an extended period.
The long-term prospective design targeting key attachment situations makes this study uniquely equipped to address this significant gap in our understanding of how early relationships shape lifelong emotion regulation capacities.
Method
The sample consisted of 102 adults who had participated in the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) since birth. This meant infant assessment data was available for them.
Infant Assessments
When participants were 12 and 18 months old, their attachment security with their mothers was directly assessed usingAinsworth’s Strange Situation procedure.
This is a standardized laboratory method that involves brief separations from and reunions with the mother, as well as interaction with a stranger.
Infant behaviors during the reunions are coded to classify them as securely attached or insecurely attached (avoidant or resistant/ambivalent).
Adult Assessments
Participants who were involved in romantic relationships lasting at least 4 months in adulthood were assessed at around ages 20, 23, 26, and 35.
Couples discussed a major unresolved relationship conflict on video for 10 minutes. Trained raters later coded these conflict discussion videos for expression of specific emotion regulation strategies (e.g. balanced-regulation, hypo-regulation, hyper-regulation).
Additional Measure
Friendship security with best friend at age 16 was assessed through interviewer ratings. Participants described their closest friendship, which interviewers scored for overall friendship security.
Results
Stable Infant Insecurity
Infants classified as insecurely attached to their mother at both the 12-month and 18-month assessments were considered stably insecure.
In adulthood, these individuals with a history of stable infant attachment insecurity displayed poorer emotion regulation habits when discussing relationship conflicts with romantic partners.
Additionally, stably insecure infants as infants showed greater hypo-regulation as adults during conflict discussions. This involves suppressing emotional displays, avoiding engagement, and interacting only at a superficial level without depth or intimacy.
Unstable Infant Insecurity
Infants classified as insecurely attached at only one of the two assessment points (12 or 18 months) were considered unstably insecure. Their insecurity was more sporadic over time.
As adults having conflict discussions with romantic partners, these individuals with a history of unstable infant attachment insecurity displayed higher rates of hyper-regulation strategies.
Friendship Insecurity
Participants who felt less secure in their closest friendship at age 16 also showed worse balanced-regulation, greater hypo-regulation, and more hyper-regulation during adult romantic relationship conflicts.
Insight
Infant attachment security serves as the prototype (internal working model) for how people regulate and express emotions in close relationships into adulthood.
Theseinitial working modelsessentially serve as a relational and regulatory prototype that persists unconsciously across development.
Additionally, the type of insecurity – whether stable or unstable – provides insight into caregiving histories.
Stable insecurity stems from more consistent harshness or deprivation, leading infants to suppress displays (hypo-regulation) for self-protection chronically. Unstable insecurity reflects more erratic care, teaching infants to heighten emotionality in hopes of receiving comfort when available (hyper-regulation).
In this way, internal working models and expected regulation strategies formed under varying conditions of early attachment insecurity go on to systematically guide emotional reactions and regulation efforts in close relationships through adulthood, for better or worse.
Strengths
Limitations
Clinical Implications
Suggests attachment security is vital for fostering constructive emotion regulation. Tailored therapeutic approaches may benefit individuals with different attachment-related regulation strategies.
Individuals displaying hypo-regulation strategies (suppression, avoidance) likely developed these means of managing distress to prevent further harm, rejection, or loss of caregiver support in childhood.
Treatment may focus first on validating these self-protective motivations and building emotional openness and trust. Gradually encouraging awareness, experience, and expression of vulnerability in safe contexts can help restore flexible regulation capacities.
In contrast, those exhibiting hyper-regulation patterns (heightening emotional displays to elicit reassurance) may have experienced unpredictable caregiving in early childhood. For them, therapy might prioritize stabilizing supports, consistency in the therapeutic relationship, and anxiety reduction before promoting emotional exploration.
