- Evidence on continuity of attachment is mixed
E - Some studies do appear to support continuity and so provide evidence to support internal working models. However, Zimmerman (2000) assessed infant attachment type and adolescent attachment to parents. The findings indicated that there was very little relationship between quality of infant and adolescent attachment.
E - This outcome is not what would be expected if the internal working models were important in development.
L - Therefore, we have to consider that the internal working model might not have validity.
