    Human Sensory Development (from t-9 to t+9 months)
    Project: The Voyager update project


    The way we humans communicate with our very young, and vice versa, is very much like a project of communicating to an alien species. Think about a baby crying, for example. The baby is sending a message to its mother, but does not have the means of communicating exactly what that message is. It is up to the mother or caretaker to decode, through trial and error and through a learned understanding of her baby, what these cries mean.

    18 months old is the earliest point at which most people are able to have memories. Salvador Dali claims to remember the womb, but for most regular folk, everything prior to this point is absolutely repressed. Freud called this the oral phase of development, in which the primary mode of stimulus is through the mouth and through taste; Erik Eriksen highlighted this period of psycho-social development as a crisis of Trust vs. Mistrust: how does a baby trust, in his dependency on a person he cannot communicate clearly with, that his message will get across and his needs will be met?

    As far as development goes, this is the period within which the senses and motor skills are refined, and after which, a toddler is able to walk - able to interact with the world as a place with which he is familiar with, not as an alien species. This development of course begins while the baby is still a fetus within the womb.

    FETAL DEVELOPMENT

    T-8 - Brain, head, and spinal cord develop rapidly, laying groundwork for the nervous system. (Carnegie Stage 14, illustrated at right)

    T-7 - End of embryonic period. The face becomes sensitive to touch.

    T-6 - The genitals, palms, and soles of feet become sensitive to touch. Taste and smell first develops, and the fetus increases its rate of swallowing when immersed in sweet tasting fluids. Swallowing reflexes decrease with bitter and sour tastes.

    T-5 - Fetal thumbsucking arises. Preference for sucking a particular thumb in utero has been shown to correlate with right or left-handedness. Abdomen and buttocks also become sensitive to touch. Reactive listening occurs at this stage, two months before the ear is structurally complete. Twins in utero at 20 weeks have no trouble locating each other and holding hands.

    T-4 - Initial responses to sound occur as early as 23 weeks gestation, and the fetus can respond to maternal speech with a slowing of the heart rate, possibly showing that the experience of speech prenatally is a foundation for the development of language postnatally. Dreaming and REM sleep is first observed around 23 weeks.

    T-2 - The entire body is sensitive to touch. Visual focus and horizontal and vertical tracking are developed in the eyes of premature babies.

    BIRTH

    Vision is statically and perfectly focused at 8-12 inches - the distance to the mother's face when breast-feeding. Full term newborns have contrast sensitivity, binocular function, distance and depth perception, color vision, and sensitivity to flicker and motion patterns.

    T+1 - Babies respond to loud noises and even subtle household sounds.

    T+3 - Vision has developed to the point where a baby will be easily distracted.

    T+5 - Vision becomes fully developed and eye coordination improves; the baby human can grasp a finger or a soft object. Babbling begins.

    T+7 - Communication through sounds, gestures, and facial expressions. Interest in mirror images develops.

    T+9 - Language and the understanding of dawns evolve.

    Ciao, nice and useful article. See also this link where you can find few pics about the 3D/4D Eco. The feto seems an alien :-)
