Module 4 Flashcards
Stages of Early Development
Prenatal Period Infancy - Birth to 15 months Toddler Period - 15 months to 2 ½ years Preschool Period - 2 ½ to 6 years The Middle Years - 6 to 12 years
Prenatal Period
The Germinal Period - First 2 weeks
Period of the Embryo - 3 to 7 weeks
Period of the Fetus - 8 weeks to birth
- One-celled zygote divides into
- 2 separate cells»_space; 4»_space; 8»_space; 16»_space; multicelled organism
- Most rapid growth of the entire life span
- Implantation one week after conception
The Germinal Period (First 2 weeks)
- Growth is rapid and orderly
- 2 directions of growth
1. Cephalo-caudal : from the head downward
2. Proximo-distal : from the center (spine) toward the extremities
Period of the Embryo (3 to 7 weeks)
Developmental Damage
- Damage at the fetal stage usually has a more global impact than damage after birth
- Rapidly growing organs are the most vulnerable
- Boys are more vulnerable
Behavior
- Fetal movements detected by 16 – 20 weeks
- Bright light flashed on the abdominal wall at 20 weeks causes changes in fetal heart rate and position
Behavior: Reflexes
Reflexes are present:
Grasp reflex appears at 17 weeks
Moro (startle) reflex at 25 weeks
Sucking reflex at 28 weeks
Maternal Stress
- High levels of stress hormones in the fetal bloodstream (Epinephrine, norepinephrine, and adrenocorticotropic hormone)
- Act directly on the fetal neuronal network to increase BP, HR and activity level
Mothers with high levels of __ are more likely to have babies who are hyperactive, irritable, of low birth weight and who have problems feeding and sleeping
anxiety
Maternal depression
- risk factor for the socioeconomic and cognitive development of children
- Women of childbearing age are prone to depression
- Premature birth
- Low birth weight
- Developmental problems - Less active, more agitated
INFANCY: Birth to 15 months
Developmental Landmarks
- Physical Development
- Language and Cognitive Development
- Emotional and Social Development
- Temperamental Differences
- Attachment
- Infant Care
Reflexes at Birth: 3 sets of reflexes critical for survival 1

Infancy: Size and Shape
- Size, shape and skills change daily
- Growth follows the same orderly sequence as prenatal growth:
- from the head downward and from the center outward
- Affected by the interaction of genes, diet, experience and the quality of care
Infancy: Vision
Near vision:
- In the first weeks of life, babies seem to focus reasonably well on objects between 7 to 10 inches away
Distance vision:
Newborn: 20/600
4 months: 20/150
Infancy: Development of Motor Abilities
- Follow the cephalo-caudal and proximo-distal sequences
- The upper part of the body is controlled before the lower part is
- The arms are controlled before the hands and fingers are
- By the end of infancy, infants have transformed reflexes into voluntary actions
Infancy: Language and Cognitive Development
- Birth – noises
- 8 weeks – babbling
- Jean Piaget’s stages of cognitive development: Sensorimotor
- Critical achievements:
Object permanence
Symbolization
Infancy: Dreams
- Reality and fantasy are not yet fully differentiated

Infancy: Emotional and Social Development
Imitative behaviors by the age of 3 weeks
Infancy: Smiling response occurs in 2 phases
- Endogenous smiling
- Occurs spontaneously within the first 2 months
- Unrelated to external stimulation - Exogenous smiling

- Intensity of reaction
9 Behavioral Dimensions (6-9)
- Threshold of responsiveness
- Quality of mood
- Distractibility
- Attention span and persistence
(Behavioral Dimensions)
- The motor component present in a given child’s functioning
- Some babies kick a lot in the uterus before they are born, they move around in their cribs, and as soon as they are old enough, they always climb or run.
- Other babies are much less active.
Activity Level
(Behavioral Dimensions)
- The predictability of such functions as hunger, feeding pattern, elimination, and the sleep-wake cycle
- Some babies have regular cycles of activity. They eat, sleep and defecate on schedule almost from birth.
- Other babies are much less predictable.
Rhythmicity
(Behavioral Dimensions)
- The response to a new stimulus, such as a food, toy or person
- Some babies delight in everything new; others withdraw from every new situation.
- The first bath makes some babies laugh and others cry; the first spoonful of cereal is gobbled up by one baby and spit out by the next.
Approach or Withdrawal
(Behavioral Dimensions)
- The speed and ease with which a current behavior can be modified in response to altered environmental structuring
*Some babies quickly adjust to change; others are unhappy at every disruption.
Adaptability
(Behavioral Dimensions)
- The amount of energy used in mood expression
- Some babies laugh when happy and howl when angry.
- Others are much calmer; they respond with a smile or a whimper
Intensity of Reaction
(Behavioral Dimensions)
- The stimulation intensity required to evoke a discernable response to sensory stimuli, environmental objects and social contacts
- Some babies seem aware of every sight, sound and touch.
- Others seem unaware of bright lights, street noises or wet diapers.
Threshold of Responsiveness
(Behavioral Dimensions)
- Pleasant, joyful, friendly behavior versus unpleasant, crying, unfriendly behavior
- Some babies are happy little people; almost anything makes them smile.
- Others are unhappy; they are ready to complain at any moment.
Quality of Mood
(Behavioral Dimensions)
- The effectiveness of extraneous environmental stimuli interfering with, or altering the direction of ongoing behavior
- Some babies forget that their diapers are being changed if someone hands them a rattle, or suck happily on a pacifier even though they would prefer a bottle.
- Others cannot be similarly distracted
Distractibility
(Behavioral Dimensions)

Easy Children
ATTACHMENT VS. BONDING
Bonding – intense emotional and psychological relationship a mother develops for her baby
Attachment – relationship the baby develops with his caregivers
- Attachment of infants to mothers
- Early separation of infants from their mothers had severe negative effects on children’s emotional and intellectual development
John Bowlby
Main points of Bowlby’s Theory
- Innate born to attach to ONE main attachment figure
- Child should receive continuous care from a single attachment figure for the first two years of life
- Long term consequences of maternal deprivation might include
* Delinquency, reduced intelligence, depression, aggression affectionless psychopathy
- Expanded on Bowlby’s observations
- Sensitive responsiveness to infant signals, such as cuddling the baby when she cries, causes infants to cry less in later months
- Close bodily contact with the mother when the baby signals for her is associated with the growth of self-reliance
Mary Ainsworth
Mary Ainsworth
- Unresponsive mothers produce anxious babies
- Secured base effect
- Enables a child to move away from the attachment figure and explore the environment
- Inanimate objects, such as a teddy bear or a blanket, also serve as a secure base (Often accompanies children as they investigate the world)
Mary Ainsworth
- Maternal sensitivity and responsiveness
- Main determinants of secure attachment
- Male infants are less likely to have secure attachments and are more vulnerable to changes in maternal sensitivity
Stranger Anxiety vs Separation Anxiety
Stranger Anxiety - 8 months
Separation Anxiety - 10 to 18 months
- Social learning and the effects of social isolation in monkeys
- Placed newborn rhesus monkeys with 2 types of surrogate mothers
1. A wire-mesh surrogate with a feeding bottle
2. A wire-mesh surrogate covered with terry cloth
Harry Harlow
social isolation of rhesus monkeys
- Terry-cloth surrogate preferred
- Provide contact and comfort
- When frightened, monkeys raised with terry-cloth surrogates showed intense clinging behavior and appeared to be comforted
- Both types were subsequently unable to adjust to life in a monkey colony
- Had difficulty learning to mate
- Females failed to mother their young
How well the mother/father relates to the newborn or developing infant
