INFANCY

The past few years, teaching developmental psychology, I always saw this part of the course as boring. Infancy was something that we had to ăget throughä as a class, so we could get on to the more interesting topics such as language development, identity crisis, self-esteem, etc.

THEN... I had another baby. I had forgotten how fascinating infants can be. As your textbook says, there is no other period of life which even comes close to infancy in the rapid pace of growth. You can literally watch a baby grow in a few weeks. Our baby, Julia, is one month old today. When she was born, she weighed 8 pounds, 4 ounces and was 20 1/2 inches long. After two weeks, she had gained two pounds and grown two inches. In other words, she had increased her weight by almost 25% and her length by 10%. For my next youngest daughter, who is 11, to show a similar growth rate, she would need to gain 20 pounds and grow five inches - IN TWO WEEKS! Think, for a minute, of that amazing growth rate. Speaking of my 11-year-old daughter, I think her comments provide a useful introduction to this chapter.
 
 
 
 

     Actually, while you may think Ronda is being inordinately harsh in her description of her baby sister,  and perhaps well on her way to causing lasting damage to the baby's self-esteem, she has hit on some very appropriate points, which are covered in your textbook as well. First of all, there is the description of what babies do.

Wolff identified six states of infants:
 

Notice that four of these states are similar to those mentioned by Ronda - crying, two types of sleep and almost asleep. While this use of time strikes an eleven-year-old as extremely boring, it is necessary for a couple of reasons. First,  all that growing takes a lot of energy, and, consequently, wears a body out. Second, babies are exposed to new stimuli constantly. My husband commented that being a newborn must be like being constantly high. (Having attended the University of California in the early seventies, he had the opportunity to witness many people in such a state!)

It is true that newborns are constantly being bombarded with new sights, sounds, smells, tastes and textures that they have never experienced before. The world is a completely different experience to infants than it is to us. Adults ignore much of the stimuli around them, because they have learned what to ătune outä. For example, you may be sitting in a computer lab at this very minute. Without looking, can you answer the following questions:
 
 
 
 

The point is, there are hundreds of questions I could ask you about the thousands of aspects of your environment that you have ignored because either a) you have learned that those pieces of information are unimportant, or b) you have experienced the same event so many times, such as walking into this room, that you pay absolutely no attention to the details - you do it automatically. According to Brazelton, infantsâ defense against this rush of stimuli is to sleep - and sleep infants do - sixteen hours a day and more. Unfortunately, these sixteen hours do not come in one lump, but are broken up into many naps, interspersed with periods of wakefulness. In our house, the longest one of those periods comes between midnight and 4 a.m. most nights! One reason knowledge of infant states is important is to understand the behavior of normal infants, and to be able to communicate to parents what kind of behavior to expect.
 
 

So, this is another reason that knowledge of infant states is important, so that when we do assess children, for example, testing their reflexes. In fact, Ronda was incorrect in stating that ALL the baby could do was sleep, cry and emit bodily fluids. In fact, babies are typically born with many reflexes. Testing these reflexes allows you to know whether an infant is functioning normally or not. If a child does not show many of the expected reflexes, it is a signal that something is wrong. Without further testing, it is impossible to say whether that something is physical (involving the muscles) or neurological
(involving the brain and/or central nervous system).
 
 
 
ASSIGNMENT # 5

1. Find an infant
2. Test for these seven reflexes described in Table 4.1 of your textbook:
 
 
 
 

    startle reflex              rooting reflex
    sucking reflex            Plantar grasp reflex
    stepping reflex             Palmar grasp reflex
    Babinksi reflex

    Do NOT test the Moro reflex or swimming reflex. I do not want to be responsible for any dropped or drowned babies.
     
     
     
     

3. Write up a description of your results. For example:
    "I tested the stepping reflex on seven-month old Brandon by holding him up so his feet were just touching on the floor. He just hung there. If he had shown the stepping reflex, he would have picked his feet up and acted like he was walking. Maybe he didn't do this because he was asleep. Maybe I should have woke him up to test the reflexes.!"

    HINT: DON'T  test reflexes on a sleeping infant.
