what are the strengths of research into infant-caregiver interactions
+ there are benefits of using controlled observations when researching infants: other activities that may distract them are controlled (control of EV's) film recordings are also used to record behavior and analyse it later - unlikely to miss behavior
This increases validity as the data is more accurate because other variables won't influence.
Also using babies reduces demand characteristics and social desirability bias
+ Practical applications: parents being taught the importance of interactions with their child, research shows those with secure attachments with parents will grow to form secure attachments later in life - a cycle of good attachments with parents
