The growth of memory during infancy
Genetic Psychology Monographs
|February 1, 1979
Summary
Infant memory capacity significantly enhances in the latter half of the first year, improving recall and tolerance for delays and interference during cognitive tasks.
Area of Science:
- Developmental Psychology
- Cognitive Neuroscience
- Infant Studies
Background:
- Understanding cognitive development in infants is crucial for identifying developmental milestones.
- Early memory development influences later learning and behavior.
Purpose of the Study:
- To investigate changes in infant cognitive abilities, specifically memory, during the first year of life.
- To determine the role of memorial capacity in developmental phenomena.
Main Methods:
- Longitudinal study tracking eight middle-class infants from 5 to 14 months of age.
- Administered tasks assessing object permanence, memory for locations/pictures, and reactions to novelty/separation.
- Monitored performance over a nine-month period.
Main Results:
- Significant enhancement in retrieving past event representations observed in the second half of infancy.
- Improved ability to compare past representations with current experiences.
- Increased tolerance for longer delays and greater interference in memory tasks.
Conclusions:
- Amplification of memorial capacity is a key factor in cognitive advancements during the last half of the first year.
- Enhanced memory abilities likely mediate diverse developmental phenomena observed in infants.
- Findings suggest a critical period for memory development in early infancy.
