![]() ![]() The episodic memory tested in the rodents was the memory of an aversive experience: a mild foot shock received upon entering in a new place. In addressing this matter, Alberini and her colleagues compared rats’ infantile memory with that when they reached 24 days old-that is, when they are capable of forming and retaining long-term memories and at an age that roughly corresponds to humans at six to nine years old. The phenomenon, referred as to “infantile or childhood amnesia,” is in fact the inability of adults to retrieve episodic memories that took place during the first two to four years of life. ![]() This is the equivalent of humans under the age of three and when memories of who, what, when, and where-known as episodic memories-are rapidly forgotten. ![]() In their study, which appears in the journal Nature Neuroscience, the researchers examined the mechanisms of infantile memory in rats-i.e., memories created 17 days after birth. Sinai and Robert Blitzer, a professor at the Icahn School of Medicine at Mt. Sinai, included: Alessio Travaglia, a post-doctoral researcher at NYU Reto Bisaz, an NYU research scientist at the time of the study Eric Sweet, a post-doctoral fellow at the Icahn School of Medicine at Mt. The other authors of the study, conducted in collaboration with the Icahn School of Medicine at Mt. “Without this, the neurological system runs the risk of not properly developing learning and memory functions.” “What our findings tell us is that children’s brains need to get enough and healthy activation even before they enter pre-school,” explains Cristina Alberini, a professor in NYU’s Center for Neural Science, who led the study. The research, conducted by scientists at New York University’s Center for Neural Science, reveals the significance of learning experiences over the first two to four years of human life this is when memories are believed to be quickly forgotten-a phenomenon known as infantile amnesia. The findings suggest that a major source of childhood amnesia is a constant rate of forgetting in childhood, seemingly resulting from failed consolidation, the outcome of which is a smaller pool of memories available for later retrieval.A new study on infantile memory formation in rats points to the importance of critical periods in early-life learning on functional development of the brain. Among adults, the distributions were best fit by the power function, whereas among children, the exponential function provided a better fit to the distributions of memories. In the present research, we examined the issue by using the cue word technique to chart the distributions of autobiographical memories in samples of children ages 7 to 11 years and samples of young and middle-aged adults. Why early memories seemingly are lost to recollection is an unanswered question. Childhood amnesia is observed in spite of strong evidence that during the period eventually obscured by the amnesia, children construct and preserve autobiographical memories. Within the memory literature, a robust finding is of childhood amnesia: a relative paucity among adults for autobiographical or personal memories from the first 3 to 4 years of life, and from the first 7 years, a smaller number of memories than would be expected based on normal forgetting. ![]()
