Every life - stage has its share of bauble — first kiss , first tax return , first twinge of certain death — but when it comes to new experiences most of us peak in infancy . Just laying there , gargling and soiling our diapers , we as baby bike through yard of firsts . It would be nice to remember some of them , as our lives slow down — as we take root into the same place chair for the 200th time , and sip from the same gaud deep brown mug . But early childhood scan as a lacuna for most of us .
Still : deal of multitude claim to commend being brook , and not all of them have done ayahuasca . Are these the great unwashed all misguided , and/or liars ? Is it possible to call back what life was like at , say , six months old ? For this week’sGiz Asks , we reached out to a numeral of experts — in pediatrics , psychology , neuroscience , etc.—to notice out . As it turns out , science still has n’t landed on why , on the nose , we forget well-nigh all of our first few age awake — but there are slew of compelling theory out there .

You likely remember the name of the grade schooling teacher who made learnedness come up alive , but when it add up to remember our lives in infancy , you draw a blank . When it comes to declaratory memories — the kind of computer storage that lets you recall specific experiences — we eventually see what the field holler infantile amnesia : the inability to remember specific experience before the age of 2 - 3 year .
This does n’t mean that our brains become mush around 2 - 3 yr . As anyone who has ever been around a babe can attest , the amount of learning that happens in the first few years is astounding . We are capable to think of information we discover ( we do n’t have to re - learn the speech we learned as infants ) , we learn how to walk , and we also get a line significant information about the humanity that sticks with us for a lifespan ( for instance , we learn whether our needs will be match or if those around us will abuse us ) . From find out a language , to learning to how to count , to learning who you could trust in the earth , a fully grown part of the piece of work of the early long time is learning ( and remembering ) newfangled data , even if we ca n’t remember specific experiences .

But there are other kinds of memory that are more similar from babyhood to adulthood . A few years ago , I worked with Lisa Feigenson at The Johns Hopkins University , and we explore infants ’ working memory , or their ability to remember entropy in the short - term . We used a prototype to research if babe were able to remember the identity of object that we hide in a box . When we made the undertaking too hard for things like counting or retention tricks , infants could , like adults , remember up to 3 objects , but , if asked to retrieve more , they experienced catastrophic forgetting . We also found that as the number of item increase from 1 to 3 , what infants could remember about the hidden objects lessen . For representative , if we ask babe to remember that a little miniature cad was in a box and then they pulled out a fiddling truck , they would keep searching for that short toy dog . But , as we increased the items in the box , infant knew that they were searching for a certain numeral of point , but they did n’t seem to retrieve what those items were . In this way , infant store architecture is much like adult storage architecture — we just get better at using it .

Few adults actually remember being a baby . Scientists call this “ infantile amnesia . ” This refers to the fact that adults report very few memories from earlier than age 3 or 4 year .
But enquiry shows that infants themselves have excellent memory board — they can recognize the face , spokesperson , and action of people around them , larn epithet for things , and delight in special objects , familiar number , and places . A study we conducted in my lab found that 3 - month - quondam babe could recognize the movement ( swing versus circling ) of an target they had seen for just 2 minute , 3 month later — at the age of 6 months !
Another grounds one might expect to remember early childhood is that the first class of our lives are recognise to have endure consequence across the lifespan . They lay the foundation for our social excited , perceptual , and cognitive development . For example , the words we learn in babyhood are retained through practice across the lifespan , as are mutual routines such as holding a fork , drinking from a cup , and putting on a brake shoe . fit in to some experts the first years mold our personality and determine the nature of our attachments to others — shaped by how firmly attach we are to our primary caretakers as infants . So , although we may not explicitly remember being an baby , the experiences of infancy are not lost — they are systematically built upon across time . Scientists have nominate a phone number of reasons for infantile amnesia ( for example , a switch from visual to verbal encryption of memories , or unionize memories around the develop horse sense of self ) but there is no agreed upon explanation .
This being said , there are big individual differences in how much we remember from babyhood and former childhood . Some of us , including myself , report have clear memories from long time two and earlier , while others describe have virtually no memories until long time 7 , 8 or 9 .
For those who wish to enhance their storage of being an infant , there are technique that can be used . Imagine yourself in the setting of the habitation you lived in as an infant . Reconstruct the quad : think the colors , reek , and sample . Imagine the sounds and sights of conversant masses and their voice . endeavor to invoke all the Mary Jane . opine see life from the position of a small child , crawling or being carried or hold . focalize on whatever sense intimate and go deeper ( the smell of baby powder , taste of Milk River , the feel of being strolled , the sound of the lullaby ) . Most mass can recover some specific computer storage in this way .

Babies do n’t have language , or witting thought , so memories of their experiences are dissimilar from what we conventionally call back of as “ memories . ” Whatever they “ think of ” is in their body , not encode in words . From the second you ’re bear you begin to make sense of what ’s perish in the world , through interact with the citizenry who take care of you : the manner you ’re harbor , the room you ’re changed , the way people speak to you . That experience informs the way you are in the world , in your body . It informs the development of your brainpower and your gut and your whole autonomic nervous organization — all those things develop through interactions with the citizenry who care for you when you ’re a infant , and all of that becomes literally part of your trunk , not just your brain .
For example , if you have a very nurturing kinship , it signals your genes to make a sealed amount of protein that determines your tenseness response . It also determines how different theatrical role of your wit get , through a cognitive process called epigenetics . The fashion your gene are turned on is influenced by the direction you ’re cared for in the earliest weeks and months of life .
Let ’s say you go somewhere you have no witting memory board of going to before , but you have a strong-arm reaction to it . It reminds you of something that ’s not in your witting memory — it ’s in your corporeal store . You have this variety of physical reaction to it even tho your conscious memory tells you “ oh , this place is o.k. , there ’s nothing dangerous about this . ” Your torso can have a dissimilar chemical reaction based on earlier experience .

I ’d wish to slightly reframe this question as “ how much do we remember from the first years of spirit ? ”
This is an eld - old debate , typically gestate as “ infantile blackout . ” The big question has been the paradox that 40 + years of enquiry has present some remarkable feats of memory that are potential in the first months and year of life story , and yet mostly , we remember nothing of our lives before the age of 2 ( the average is really 4 years ) . Why is this ?
Several reasonableness have been proposed . Sigmund Freud claimed that through we repress these early memories , they are indeed keep on — we just do n’t have accession to them ( there is zero evidence for this ) . Others have suggested that without a language system in place , we do n’t know how to map these memory , and thus can not organize and recover them . There is also the mastermind theory — although the neural systems involved in forming a memory come online pretty early in lifetime , the systems for store these memory for the long - term are unripened in those early yr ; as a answer , encode something as a memory is not translated into long terminal figure storehouse
A related to theme is that the genuine system of the brain that are involved in retrieval — most of which are in the prefrontal cortex — are immature in those early class .

Overall , study asking people to recall their early computer storage conclude that people can not remember events from before their third or fourth natal day . This is an medium frame , so naturally there ’s some variation . A few people remember upshot from even earlier than that , while many others ca n’t think back anything from before age 6 or 7 or 8 .
It ’s deserving noting that this descent of inquiry rely on the assumption that mass can really sleep together that they remember something , which is not always well-situated today , with so many photograph and picture of our first geezerhood . Do I really call up , or have I created a memory based on stories I ’ve been told , or videos I ’ve encounter ? It ’s not always easy to tell — we are very susceptible creatures , and easily build retentiveness we after believe to have experienced firsthand . That said , elision to infantile amnesia can occur if or when we experience something unique — something charged with strong emotion . Even if you do n’t call up your second natal day , you could still have a substantial visual memory of the new red shoe you got even before you turned two .
Even if we as adult can not remember events early on on , a baby or an infant can . A very large body of inquiry has shown that infants as young as 6 months old remember an event they experience very briefly for a couple of days ( and , with a monitor , much foresightful ) . So why is it that we can not remember events from our early age but infants can ? We really do not know for sure , but it is suspected that wit , linguistic process , and psychological ontogenesis in combining are the key factors . The brain undergo massive growing during our first years of life , change that most credibly affect how memories are stored and retrieved . As for language , it is suspected that when the child enters the world of spoken language ( the language explosion unremarkably starts by the end of the 2d year ) it will also touch how our memories are organize . in conclusion , from a psychological head of view , the self or the ego - awareness that starts to forge as you get honest-to-god might be central factors . When you start to have a core feeling of being someone , of being you , it influence how and what you remember .
We should also remember that block might be a good matter . We ’re not helped by remembering every detail in our life . rather we are often better off letting generalized storage and experiences steer us in our day-to-day life sentence .
