Secure attachment is an emotional bond in which a child feels safe and protected with a caregiver and uses that caregiver as a secure base to explore the environment, showing distress at separation but quick comfort upon reunion (Ainsworth's Strange Situation, AP Psych Topic 6.2).
Secure attachment is the healthiest attachment style identified in developmental psychology. A securely attached child trusts that the caregiver will be there, so the child feels free to explore new places and people. The caregiver works like a home base in a game of tag. The child ventures out, checks back, and returns for comfort when stressed.
This idea comes from John Bowlby's attachment theory, which argued that forming a bond with a primary caregiver is a biologically built-in survival mechanism (an idea he connected to Darwin's evolutionary thinking, since infants who stayed close to caregivers were more likely to survive). Mary Ainsworth then tested attachment with her Strange Situation procedure. Securely attached infants explored while the caregiver was present, showed some distress when the caregiver left, and were easily soothed when the caregiver returned. That reunion behavior is the giveaway. Insecure infants either avoided the caregiver or clung and stayed upset.
Secure attachment lives in Topic 6.2 (Social Development in Childhood), with roots in Topic 6.1's coverage of physical and lifespan development. It's one of the core ideas you need for explaining how early relationships shape later social and emotional functioning. The AP exam expects you to apply attachment concepts, not just define them. You should be able to read a scenario about an infant's behavior in the Strange Situation and label the attachment style, explain why responsive caregiving produces security, and connect attachment to broader developmental frameworks like Erikson's trust vs. mistrust stage. Secure attachment is also a favorite for research-methods crossover questions, since Ainsworth's procedure is a classic example of structured observation.

Attachment Theory (Unit 6)
Secure attachment is one outcome within Bowlby's broader attachment theory. Bowlby supplies the why (attachment is an evolved survival mechanism), and secure attachment describes what the bond looks like when caregiving is consistent and responsive.
Separation Anxiety (Unit 6)
Securely attached infants do show separation anxiety, and that's actually a good sign. Mild distress when the caregiver leaves means the bond exists. The difference shows up at reunion, when secure infants calm down quickly.
Erikson's Stages of Psychosocial Development (Unit 6)
Secure attachment maps almost perfectly onto Erikson's first stage, trust vs. mistrust. A responsive caregiver helps the infant resolve that crisis on the trust side, which is basically secure attachment described in Erikson's vocabulary.
Authoritative Parenting Style (Unit 6)
Authoritative parenting (warm but with clear expectations) is the parenting style most associated with secure attachment. Both involve a caregiver who is responsive and reliable, and both predict better social outcomes later.
Secure attachment shows up most often in multiple-choice scenario questions. A stem describes an infant's behavior, often in a Strange Situation setup, and asks you to identify the attachment style or the researcher behind the concept. You should be able to name Bowlby and Ainsworth, explain how evolutionary theory supports Bowlby's claim that attachment is innate, and identify the defining behaviors of secure attachment (exploring with the caregiver present, distress at separation, comfort at reunion). Practice questions also ask application-level things, like proposing an intervention for a child who hasn't developed secure attachment, where the answer centers on increasing consistent, responsive caregiving. No released FRQ has required this term verbatim, but attachment concepts fit naturally into FRQs about development, research methods, or applying a concept to a scenario.
All attached infants may react to separation, so don't use crying alone to classify them. Secure infants explore freely with the caregiver nearby, get upset at separation, and are quickly soothed at reunion. Avoidant infants ignore the caregiver at reunion, and anxious/ambivalent infants stay distressed and can't be comforted. The reunion behavior, not the separation, is what separates the styles.
Secure attachment means a child uses the caregiver as a secure base, exploring confidently when the caregiver is near and seeking comfort when stressed.
John Bowlby developed attachment theory and argued attachment is an evolved survival mechanism, an idea consistent with Darwin's theory of evolution.
Mary Ainsworth's Strange Situation is the classic procedure used to classify attachment styles by observing infant behavior during separation and reunion.
The clearest sign of secure attachment is the reunion, where the child is distressed by separation but calms quickly when the caregiver returns.
Secure attachment develops from consistent, responsive caregiving and connects to Erikson's trust vs. mistrust stage and to authoritative parenting.
On the AP exam, expect scenario-based questions that ask you to classify an attachment style or explain how caregiving produces it.
Secure attachment is an emotional bond in which a child feels safe with a caregiver and uses them as a secure base to explore. In Ainsworth's Strange Situation, secure infants show some distress at separation but are easily comforted at reunion. It's covered in AP Psych Topic 6.2, Social Development in Childhood.
No. Some separation distress is actually typical of securely attached infants because it shows the bond exists. Insecurity shows up at reunion, when avoidant infants ignore the caregiver and anxious/ambivalent infants can't be soothed.
Secure infants explore with the caregiver present and calm down quickly when the caregiver returns after separation. Insecure infants either avoid the caregiver at reunion (avoidant) or remain distressed and clingy (anxious/ambivalent). Reunion behavior is the key distinction Ainsworth measured.
Both, in different ways. Bowlby created attachment theory, arguing the infant-caregiver bond is biologically built in for survival. Ainsworth designed the Strange Situation procedure that identified secure attachment as a distinct, observable style.
Secure attachment lines up with Erikson's first psychosocial stage, trust vs. mistrust. A responsive caregiver helps the infant develop basic trust, which is essentially the same outcome attachment theorists call security.
