Unit 6: Development Flashcards
Zygote
the fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo
embryo
the developing human organism from about 2 weeks after fertilization through the second month
fetus
the developing human organism from 9 weeks after conception to birth
Teratogens
agents, such as chemicals and viruses, that can reach the embryo or fetus during parental development and cause harm
Fetal alcohol syndrome (FAS)
physical and cognitive abnormality in children caused by a pregnant woman’s heavy drinking. In severe cases, signs include a small, out-of-proportion head and abnormal facial features
Habituation
decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner.
Nature vs. Nurture
how our genetic inheritance (our nature) interacts with our experiences (our nurture) to influence our development
Continuity vs. Change
certain parts of development are gradual and continuous, while other parts change abruptly in separate stages
Stability vs. Change
certain traits persist through life while others change as we age
Authoritarian
parents impose rules and expect obedience
Permissive indulgent
Parents submit to their children’s desires. They make few demands and use little punishment
Permissive Neglectful
Parents don’t show compassion to their children. They make few demands and use little punishment
Authoritative
parents are both demanding and responsive. They exert control by setting rules and enforcing them, but they also explain the reasons for the rules. And, especially with older children, they encourage open discussion when making the rules and allow exceptions.
Stranger Anxiety
the fear of strangers that infants commonly display, beginning by about 8 months of age
Attachment
an emotional tie with another person; shown in young children by their seeking closeness to the caregiver and showing distress on separation
Self-concept
children 15-18 months begin to be able to recognize themselves in the mirror, 2-5 years they can describe their traits, and from 8-10 years they begin to have a better understanding of self-image
Contact Comfort Theory (Harry Harlow)
disproved the belief that love is only based on physical needs, found that baby monkeys needed compassion and love from parental monkeys to promote healthy development
Critical period
an optimal period early in the life of an organism when exposure to certain stimuli or experiences produces normal development
Imprinting (Konrad Lorenz)
the process by which certain animals form strong attachments during an early-life critical period. Lorenz found in his experiments that the ducklings followed him - only valid for animals; not children)
