Attachment theory
A relationship with a familiar caregiver can organize proximity seeking and exploration.
Theory The classification describes how this account is used here; it is not an evidence rating.
Central claim
Infants form selective emotional bonds with familiar caregivers that function as a secure base for exploration and a safe haven under threat, shaping relational expectations through repeated caregiving interactions.
Proposed mechanism
Under threat, attachment behavior promotes contact with an attachment figure; felt security can support exploration. Repeated interactions inform expectations, but patterns are relationship-specific and open to change.
Evidence: (Spielman et al., 2020)
What would it predict?
Separation and reunion should reveal differences in how an infant uses a familiar caregiver for comfort. Interpretation also needs home observation and sensitivity to cultural caregiving routines.
An original test formulation derived from the account, not a claim that this exact study was performed.
Evidence and status
Bowlby's (1969) evolutionary-developmental formulation and Ainsworth and colleagues' (1978) Strange Situation observations jointly shaped the field. OpenStax describes these infant attachment patterns and Harlow's (1958) primate studies showing that comfort and responsiveness matter beyond feeding alone.
Evidence: (Spielman et al., 2020)

John Bowlby; Mary Ainsworth; Mary Main and many later researchers

Apply the explanation
Original teaching scenario
An infant explores an unfamiliar room, seeks comfort after a brief separation and then resumes exploration with a familiar caregiver nearby.
Constructed for learning. This scenario does not report an empirical result.
Common confusion: Temperament alone or permanent adult relationship labels
Attachment describes the organization of a specific caregiver-child relationship rather than an infant's general reactivity alone or an unchangeable adult personality type.
Evidence: (Spielman et al., 2020)
Limits and alternatives
- An infant classification is not a permanent personality type or an adult dating diagnosis. Context, multiple caregivers and measurement conditions matter; observational associations alone do not establish causation.
Evidence: (Spielman et al., 2020)
