Evaluation

• Methodological issues

  -Hazan and Shavers research used self report method and in Bailey's research interviews are used which introduces social desirability bias. Adults may give answers which make it look like they have a positive relationships with their child which decreases validity.
• Deterministic

  -It suggests poor experiences with primary caregiver in infancy will result in negative and insecure internal working model which will later effect social relationships.

  -Underestimates free will, have conscious ability to change behaviour so cause a child sensitively even if they had poor parental experiences previously.
