What the study found
Prior social feedback from an experimenter was linked to later differences in infant attention. Infants who were rarely responded to later showed higher vigilance, including more frequent visual scanning and shorter response latencies, than infants who received high response rates.
Why the authors say this matters
The authors suggest that contingent social feedback may help organize infant attention in later settings. They also say the findings provide strong experimental evidence and suggest possible mechanisms for interventions supporting adaptive outcomes.
What the researchers tested
The researchers experimentally manipulated social interactions in 6- to 7-month-old infants by changing the form and timing of an experimenter's responses to infants' looks and vocalizations. They used four response schedules that varied in contingency, meaning how often the adult responded to infant behavior, and joint focus, meaning whether the response matched the infant's attention.
What worked and what didn't
Experimenters' prior contingency predicted later infant attention in a behavioral vigilance task with a new adult. Low contingency, or rare responding, was associated with higher vigilance, while highly vigilant infants also attended more rigidly to highly salient stimuli across task trials.
What to keep in mind
The abstract does not describe specific limitations beyond the study's scope. The findings are reported for infants aged 6 to 7 months and for the particular interaction and vigilance tasks used here.
Key points
- Infants who were rarely responded to later showed higher vigilance.
- Higher vigilance included more frequent visual scanning and shorter response latencies.
- The experiment manipulated both contingency and joint focus in adult-infant interactions.
- Contingency, meaning how often the adult responded to infant behavior, predicted later attention.
- The abstract does not list additional limitations.
