Unit 6: Developmental Psychology Flashcards
Developmental psychology
a branch of psychology that studied physical, cognitive, and social change throughout the life span
How do women and men differ concerning egg/sperm production?
Women are born with all the immature eggs they will ever have, whereas men produce sperm cells nonstop from puberty
Zygote
a 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
- “monster makers”
agents such as chemicals and viruses that can reach the embryo or fetus during prenatal development and cause harm (why women are asked to avoid smoking/alcohol when pregnant)
FAS
- Fetal Alcohol Syndrome
- physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. in severe causes, it can produce small/disproportionate head and abnormal facial features
Habituation
decreasing responsiveness with repeated exposure to a stimulus
** children lose interest in repeated exposure to the same toys/actions/sounds
Maturation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience
Infant brain development/memory
- we consciously recall little from before the age of four; despite this, our brain was still processing and storing information
- the brain areas underlying memory (hippocampus, frontal lobes) continue to mature through/during adolescence, and we lose the infantile amnesia that comes with being young
Schema
- a concept or framework that organizes/interprets information
- maturing builds schemas which we use in later experiences
Assimilation
interpreting our new experiences in terms of our existing schemas
Accommodation
adapting our current understanding/schemas to incorporate new information
Lev Vygotsky
- child development researcher
- emphasized how the child’s mind grows through interaction with the social environment
- focused on scaffolding and zone of proximal development
Scaffolding
a framework that offers children temporary support as they develop higher levels of thinking
Zone of proximal development
the zone between what a child can and cannot do (what they can do with help)
Autism spectrum disorder
a disorder that appears in childhood and is marked by significant deficiencies in communication and social interaction, and by rigidly fixated interests and repetitive behaviors
Piaget’s stages of cognitive development
SENSORIMOTOR
- birth to nearly 2 years old
- experiencing the world through senses and actions
** object permanence, stranger anxiety
PREOPERATIONAL
- 2 to about 6-7 years old
- representing things with words and images: using intuitive reasoning rather than logical
** pretend play, egocentricism
CONCRETE OPERATIONAL
- around 7-11 years old
- thinking logically about concrete events; grasping concrete analogies, and performing arithmetical operations
** conservation, mathematical transformations
FORMAL OPERATIONAL
- around 12 through adulthood
- abstract reasoning
** abstract logic, potential for mature moral reasoning
Stranger anxiety
a 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 their caregiver and showing distress upon separation
Harry Harlow’s attachment study
separating a monkey from it’s mother at birth and observing it’s attachment to a cloth shaped like a mother
- study recognized that intense attachment is not always associated with nourishment
- human attachment is similar; consists of one person providing a secure base from which to explore and a safe haven when stressed that changes with age/development
