In studies investigating infant-caregiver attachment classifications, researchers observe infants aged 12 to 18 months in a novel play environment with their fathers (such as Marcus and his son, Leo). The researchers currently write a continuous, detailed narrative of every movement and vocalisation made by both Marcus and Leo, recording their own subjective opinions about the infant's distress levels.
Explain how this observational study could be improved by using structured behavioural categories.
