Evaluate research into infant-caregiver interactions
:) - Controlled observations in a controlled experimental setting with standardised procedures and operationalised behavioural categories with filming from multiple angles. High reliability as can be repeated to check consistency.
:) - These observations are less prone to demand characteristics as obviously babies are unaware an experiment is taking place and thus will not change their natural behaviours.
:( - Observations susceptible to observer bias as they require subjective interpretation from researches who may perceive behaviour as being something else to what it really is, this can lower the validity.
:( - Observations only look at the changes in hand movements and gestures. It is very difficult to be certain that the moves or gestures etc, were actually deliberate or accidental, this reduces the value of the insight into caregiver-infant interaction.
:( - These studies don't tell us the purpose of synchrony or reciprocity, they simply state that it happens and don't imply anything about why and what the purpose is. Other studies have said that it is important in the development of empathy and morals.
:( - Conducting research into mother-infant interactions is controversial as it sates that certain people may be at a disadvantage for certain reasons. ie. Mothers going back to work...
