(P) A problem with caregiver infant interaction is that it is not found in all cultures.
(E) Le Vine et al (1994) reported that Kenyan mothers have little physical interactions or physical contact with their infants, but such infants do have a high proportion of secure attachments
(E) Therefore, the research may be ethnocentric because it ignores how attachments may be formed within other cultures
(L) This reduces the validity of the research as all cultures should be taken into account in order to generalise findings as much as possible
Evaluation (PEEL structure): against
(P) Observations do not tell us the purpose of reciprocity and interactional synchrony
(E) For example, Feldman points out that synchrony and reciprocity simply describe behaviours that occur at the sametime
(E) These can reliably be observed, but it still doesn't tell us the purpose
(L) Further research may be needed to tell us the purpose of these interactions.
