Insights
Infant persistence and maternal teaching are key predictors of early cognitive development. Both infant persistence (measured early) and mothers' teaching at 6 months significantly impact cognitive status by 14 months.
Area of Science:
- Developmental Psychology
- Child Cognitive Development
- Early Childhood Education
Background:
- Early childhood cognitive development is influenced by a complex interplay of infant and caregiver factors.
- Understanding these factors is crucial for identifying early developmental trajectories and potential interventions.
- Low-income dyads present unique challenges and opportunities for studying these influences.
Purpose of the Study:
- To investigate the independent contributions of infant persistence and maternal teaching to infant cognitive development.
- To examine these contributions at two key developmental points: 6 and 14 months of age.
- To determine the predictive power of early infant persistence and maternal teaching on cognitive status at 14 months.
Main Methods:
- A longitudinal study of 65 low-income mother-infant dyads.
- Infant persistence assessed via a persistence task (6 months) and the Behavior Record Scale of the Bayley Scales of Infant Development II (14 months).
- Maternal teaching evaluated using the Nursing Child Assessment Satellite Training (NCAST) teaching scale (6 and 14 months).
- Infant cognitive development measured by the Mental Scale of the Bayley Scales of Infant Development II (14 months).
Main Results:
- Infant persistence at 6 and 14 months uniquely predicted cognitive development at 14 months.
- Maternal teaching at 6 months also uniquely predicted infant cognitive development at 14 months.
- These findings highlight the distinct roles of infant characteristics and caregiver behaviors.
Conclusions:
- Infant persistence is a stable trait measurable early in life.
- Both early infant persistence and maternal teaching serve as direct pathways to cognitive development in the first year.
- Interventions supporting maternal teaching and fostering infant persistence may enhance early cognitive outcomes.
Abstract:
This study examined the relative contributions of infants' persistence and mothers' teaching at 6 and 14 months to infants' cognitive development at 14 months in a sample of 65 low-income mother-infant dyads. Infants' persistence was assessed from a videotaped persistence task at 6 months and from the Behavior Record Scale of the Bayley Scales of Infant Development, 2nd ed. (BSID II) at 14 months. Mothers' teaching was assessed from a videotaped teaching interaction at 6 and 14 months using the Nursing Child Assessment Satellite Training (NCAST) teaching scale. Cognitive development at 14 months was based on the Mental Scale, BSID II. Infants' persistence at both ages and mothers' teaching at 6 months each explained unique variance in infants' cognitive status at 14 months. Persistence appears to be a stable quality that can be measured early on, and both infants' early persistence and mothers' teaching are direct pathways to cognitive status at the start of the second year.

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
