Insights
Preterm infants often experience under-diagnosed learning delays. This study found preterm infants showed less goal-directed behavior and delayed intentionality in problem-solving tasks compared to full-term infants.
Area of Science:
- Developmental Psychology
- Pediatric Neurology
Background:
- Preterm infants face risks for developmental delays in motor, perceptual, and cognitive areas.
- Learning delays in preterm infants are often under-diagnosed in early life.
Purpose of the Study:
- To longitudinally assess behavioral performance and learning in means-end problem-solving tasks.
- To compare preterm (PT) and full-term (FT) infants' performance across multiple age points.
- To identify early markers for learning delays in at-risk infants.
Main Methods:
- Longitudinal evaluation of 30 preterm and 23 full-term infants at 6, 9, 12, 18, and 24 months.
- Utilized two means-end problem-solving tasks: towel pulling and turntable rotation.
- Assessed behavioral performance, including goal-directed and non-goal-directed actions, and task success rates.
Main Results:
- Preterm infants exhibited more non-goal-directed and less goal-directed behavior than full-term infants.
- Preterm infants demonstrated a delayed emergence of intentionality in both problem-solving tasks.
- Behavioral performance amount and variability correlated with task success, varying by age.
Conclusions:
- Means-end problem-solving tasks may aid in the early detection of learning delays in preterm infants.
- Identifying age-specific behavioral indicators can guide interventions for at-risk infants.
- Documented learning differences highlight the need for targeted early support for preterm infants.
Abstract:
Preterm infants are at risk for delays in motor, perceptual, and cognitive development. While research has shown preterm infants may exhibit learning delays in the first months of life, these delays are commonly under-diagnosed. The purpose of this study was to longitudinally evaluate behavioral performance and learning in two means-end problem-solving tasks for 30 infants born preterm (PT) and 23 born full-term (FT). Infants were assessed at 6, 9, 12, 18, and 24 months-old in tasks that required towel pulling or turntable rotation to obtain a distant object. PT infants performed more non-goal-directed and less goal-directed behavior than FT infants throughout the study, resulting in a lower success rate among PT infants. PT infants showed delayed emergence of intentionality (prevalence of goal-directed behaviors) compared to FT infants in both tasks. Amount and variability of behavioral performance significantly correlated with task success differentially across age. The learning differences documented between PT and FT infants suggest means-end problem-solving tasks may be useful for the early detection of learning delays. The identification of behaviors associated with learning and success across age may be used to guide interventions aimed at advancing early learning for infants at risk.
