This study examined whether there were differences in the joint attent
ion behaviours of adolescent mothers and toddlers and adult mothers an
d toddlers. The timing of mothers' attention-directing behaviours (i.e
. maintaining, introducing and redirecting) as well as the specific be
haviours (i.e. showing, offering and demonstrating toy) they used to d
irect their toddlers' attention to toys were observed. The observers a
lso coded the specific joint attention behaviours that the toddlers us
ed. The findings showed that the adolescent mothers redirected their t
oddlers' attention away from a toy they were interested in to a differ
ent toy more often and used fewer introducing behaviours than the adul
t mothers. Toddler age was also inversely related to mothers' redirect
ing behaviour. The results also indicated that the adolescent mothers
demonstrated toys and interfered with their toddlers' ongoing play beh
aviour more frequently than the adult mothers. Toddler age was also in
versely related to the frequency with which both groups of mothers dem
onstrated toys and positively related to the frequency with which moth
ers showed toys. The toddlers born to the adolescent mothers showed fe
wer social initiations and a higher frequency of non-verbal responses
than the toddlers born to the adult mothers. Toddler age was negativel
y related to the frequency of non-verbal responses.
