Paper
What is the paper investigating?
A randomised controlled trial to test the effect ofpromoting caregiver contingent talk on language development in infants from diverse socioeconomic status background
What is the backgroud of this paper
Early language skills are critical for later academic success. Lower SES)children tend to start school with limited language skills compared to advantaged peers.
What was the method used?
Randomised controlled trial with high and low SES families.
11-month olds and their caregivers were randomly allocated to either a contingent talk intervention or a dental health control.
Families in the language intervention watched a video about contingent talk and were asked to practise it for 15min/day for a month. Caregiver communication was assessed at baseline and after 1 month. Infant communication was assessed at baseline, 12, 15, 18 and 24 months
What was the results?
At baseline, social gradients were observed in caregiver contingent talk to their 11-month olds (but not in infant communication).
At posttest, when infants were 12 months old, caregivers across the SES spectrum who had been allocated to the language interventiongroup engaged in significantly more contingent talk.
Lower SES caregivers in this intervention group also reported that their children produced significantly more words at 15 and 18 months.
Effects of the intervention did not persistat 24 months.
Instead expressive vocabulary at this age was best predicted by baseline infant communication, baseline contingent talk and SES.
What was the conclusion of the paper?
A social gradient in children’s communication emerges during thesecond year of life.
A low-intensity intervention demonstrated that it is possible to increase caregiver contingent talk and that this is effective in promoting vocabulary growth for lower SES infants in the short term.
However, these effects are not long-lasting, suggesting that follow-up interventions may be necessary to yield benefits lasting to school entry.
