Unit 4 Flashcards
Nature vs Nurture
Nature refers to heredity - the influence of inherited charactersitics on personality and physcial growth. Nurture refers to the influence of the environment on all of those same things that includes parenting styles and environmental surroundings
Genetics
science of heredity. This is understanding how genes transmit human characteristics and traits involves defining a few basic terms
Dominant gene
This gene will always be expressed in the observable trait
Recessive genes
tend to recede or fade into the background when paired with a dominant gene
dizygotic twins
this is when two eggs are fertilzed during pregnancy
monozygotic twins
meaning the egg spit from one egg to create two babies
germinal period
The first part of pregnancy (for about 2 weeks)
embryonic period
lasts from about two weeks after conception to eight weeks. During this time the cells continue to specialize and become various organs of the human. At the end of 8 weeks, all organs are there even though they are not functioning properly
critical periods
times during which environmental influence can have an impact. These consist of the heart ( 2 weeks to 6 weeks and the limbs (3.5 to 8 weeks)
teragtogen
This is any birth defect that is caused by a drug
fetal alcohol syndrome
a series of physical and mental defects including stunted growth, facial deformities, and brain damage
fetal period
period of time from 8 weeks to the conception of birth . This is the time that the baby grows the most
sensorimotor stage
first stage of Piaget’s stages. Occurs from birth to age 2. This is when they learn about all of their senses. They also have a full understanding of object permanence by the end of the stage
preoperational stage
ages 2-7. a time of developing language and concepts. During this stage a child will go through the understanding of egocentrsim, centration, conservation , and irreversibility.
centration
wanting the piece of pie that has two slices regardless of if the other slice is bigger
conservation
conservation of water example
concrete operations stage
ages 7-12. children become capable of conservation and reversible thinking. They are able to recognize that certain fantasy’s are not real. They cannot think abstractly though
Formal operations stage
ages 12-adulthood. Abstract thinking becomes possible. Teenagers are able to think hypothetically .
Who came up with the four stages of cognitive development?
Piaget
Vygotsky’s theory
He had theories about development in children. But rather than dealing with objects, he dealt with social and culture factors
What are the 5 stages of Language development
Cooing, babbling, one-word speech, telegraphic speech, whole sentences
cooing
around 2 month old. vowel-like sounds
babbling
at about six month, infants add consonant sounds to the vowels which at times sounds like real speech.
one-word speech
just before age 1, most children are able to say words
telegraphic speech
around 1 and half. toddlers begin to string words together to form short sentences
Whole sentences
by age 6, they are usually as fluent as most adults
temperament
the emotional and behavioral characteristics that are fairly well established at birth. There are 3 basic temperament styles: Easy, Difficult, Slow to warm up
What are the attachment styles (Mary Ainsworth)
Secure, avoidant, ambivalent, disorganized - disoriented
Secure attachment
these babies did not like when the stranger came into the room and were very happy that the mother was in there
Avoidant
willing to explore. They did not “touch base” with their mothers and reacted very little to her return
