expressionstested for may be confused with other movements rather than synchrony
e.g tongue thrust reflex babies are born with includes stickingtongue out
difficult to distinguish between general physicalactivity & imitation
? internal
not certain these expressions are in directresponse to cg
cannot accuratelymeasureextent to which they reinforce att bond due to confoundingvariables
X culturally bias research?
reciprocity & i.s found in western cultures
e.g reported that kenyan mothers have little interaction with their kids but still go onto form normal att
? population
these cg interaction not essential for att in allcountries
findings cannot be generalised to att in wider population
* research used controlled observations?
observations of mother - infant interactions well controlled & filmed so fine details can be recorded & analysed
babies do not know they are being observed/understandpurpose of research so behaviour is natural
reliable & valid
rm used are well controlled & standardised
allows for replicability
nature of sample means no risk of dcs influencing results
increases ecological validity
X observations do not explain behaviour?
feldman 2012 points out that r & i.s simply describebehaviours that occur
does not tell us purpose of these behaviours that babies demonstrate
? internal
observational methods used to identify these interactions do notexplain why infant behaves this way
cannot establish cause & effect relationship between infantsbehaviour & formation of att bond
* imitative behaviour forms basis for social development
meltzoff 2005 believes that by imitating cg behaviour associating their own actions with this behaviour & then projecting their internal experiences onto others infants begin to understand mental state of others
reseach into r & i.s explains how children begin to understand what others think & feel
fundamental for conducting social relationship
evidence to support that these aspects of cg infant interactions are essential for forming & reinforcing att bond
