Secrets of the baby brain: What can they remember at 3 days old?
As babies grow, memory development is an ongoing process that begins almost immediately early in their lives. Babies as young as three days old already show a surprising ability to remember their mother's voice, "Empirical Research" shows. This study challenges our understanding of infant memory development and reveals its importance in brain neuroscience.
Not only can babies remember their mother's voice within three days of birth, but they can also build a more complex memory system in subsequent life.
Research on memory development usually focuses on the growth stages of infants, young children and adolescents. However, the memory development of adults and the elderly is equally important and cannot be ignored. Memory plays a key role throughout an individual's lifespan. Especially in early childhood, memory development will reflect their knowledge and understanding of the world.
Types of memory: explicit memory and implicit memory
Explicit memories, memories that can be actively recalled later, often develop rapidly early in a baby's life. Studies have pointed out that explicit memory relies on structures in the medial temporal lobe of the brain such as the hippocampus and parahippocampal cortex, and these structures do not reach maturity until infants are eight to ten months old.
Structural development in the brain shows that infants' memory abilities are closely linked to cognitive development over time.
On the other hand, suggestive memory appears earlier and is influenced by early development systems such as the basal ganglia, cerebellum and brainstem. These systems help build fundamental abilities related to motor learning and memory. As neural cues become myelinated, the baby's information processing speed increases.
The development of working memory
Working memory is another key component of memory development. According to Baddeley's model, working memory consists of three parts: the central executive system, the phonological loop, and the visuospatial sketch. The relationship between these parts develops gradually with age.
During the growth process from infant to toddler, working memory performance will increase linearly with age.
Not only that, the central executive system also plays a central role in guiding infants' attention and problem solving. As children grow, the processing of information will become more and more efficient, and the storage space will become larger.
The connection between emotion and memory
The impact of emotion on memory has received increasing attention. Research shows that emotionally intense experiences are more likely to be remembered, and babies are especially sensitive to positive emotional events. When the researchers showed shapes associated with positive emotions, the babies showed stronger signs of memory.
If babies form positive emotional connections during the memory process, their ability to recall events will be improved.
These observations not only provide insights into infant memory development, but also suggest potential for future applications in education and psychological development.
Conclusion
In summary, babies' memory abilities begin to develop from birth, and they can remember important information even when they are only three days old. This is not only about the connections individuals make early in life, but also the foundation for future learning, social interaction and self-understanding. With the deepening of research, can we fully understand the mysteries of infant brains, and how can we make full use of this knowledge to promote their growth and learning?
