care-giver infant intereactions

The two concepts of care-giver infant reactions are [blank_start]reciprocity[blank_end] and [blank_start]interactional synchrony[blank_end]

Aisha moves her head and Lola repeats this, this is called [blank_start]riprocity[blank_end]

Psychologists [blank_start]Metzlof[blank_end] and [blank_start]Moore[blank_end] conducted the study of interactional synchrony

In the systematic study of interactional synchrony children as young as how old imitated facial expressions and hand movements

The adult model pulled one of how many facial expressions?

Other psycologists carried out studies with [blank_start]two month[blank_end] old infants. They displayed a [blank_start]video[blank_end] of the mother interacting with the infant. The infant tried to [blank_start]attract the mothers attention[blank_end] but on rejection [blank_start]turned their heads[blank_end]. This suggests that behaviours are [blank_start]innate[blank_end] and not learned.

[blank_start]Isabella[blank_end] et al found that the more [blank_start]strongly[blank_end] attached the infant is, the [blank_start]greater[blank_end] the interacial synchrony
