An internal working model resembles a schema in that it is a mental structure in long-term memory that provides the basis for forming expectations. In the case of attachment, this relates to a person’s expectations about relationships and their own success as a parent.
Strength (early attachment influence)
Supporting Research - as suggested by Bowlby’s view, that an infant’s first relationship with a primary attachment figure forms a mental representation for later relationship.
Limitation (early attachment influence on later life)
Mixed Findings – In contrast to the support for the internal working model, findings from Zimmerman et al’s (2000) longitudinal studies yielded mixed results. They found that childhood attachment type was not a good predictor of attachments in adolescence, and that life events often altered secure attachments to an insecure type in adulthood.
