Lifespan Development Flashcards
The offspring of women who consume alcohol during pregnancy are most likely to have serious structural abnormalities involving the brain, heart, eyes, limbs and external genitalia when the woman drinks alcohol during which trimester?
first
most traits are ____, which means they are influenced by multiple genes,.
polygenic
child who is homozygous
has inherited the gene from both parents
a child who is heterozygous
has inherited the gene from only one parent
When a trait is due to a recessive gene, a child must be ______, with regard to that gene in order to display that trait.
homozygous
____ refers to a person’s genetic inheritance
genotype
_____ refers to a person’s observed characteristic (which are due to a combination of heredity and environment)
phenotype
Heredity accounts for only ____ % of variability for many characteristics

Bronfenbrenner’s Ecological model
believed development involves interactions between the person and their environment
Ecological model: describes context in terms of 5 environmental systems:
1-microsystem: child’s immediate environment and relationships within the
home, school, etc
2- mesosytem: interactions between components of the microsystem;
EX: influence of family factors on the child’s behavior at school
3- exosystem: elements in the broader environment that affect the child’s
immediate environment (EX: parent’s workplace, school board, community
agencies, mass media)
4- macrosystem: overarching influences like cultural beliefs and practices,
economic conditions, political ideologies
5- chronosystem: environmental events that occur over a person’s lifespan
and impact them in ways that depend on their circumstances and and
developmental stage (EX: SES or immediate and long term effects of
change in family structure.
Rutter’s Indicators
accurate predictors of child psychopathology
1-severe marital discord
2- low SES
3- overcrowding/ large family size
4- parental criminality
5- maternal psychopathology
6- placement of the child outside the home
findings:
high risk children can be resilient and such negative effects are not irreversible if they receive fewer stressors following birth, had easy temperaments, and had support from a caregiver.
The contribution of heredity to an observed characteristic can be expressed in terms of heritability estimate, which indicates the extent to which phenotypes vary within groups as the result of differences in ______.
genotype
Research investigating the impact of early stress on development suggests that high-risk babies are less likely to have negative outcomes when babies experience fewer stressors following birth and have an easy temperament marked by a high degree of _______ and good communication skill.s
social responsivity
Research by Werner and Smith (1982)
Three types of genotype environment correlation have been proposed to explain how genetic and environmental factors combine to produce an individual’s attributes:
1_____
2_____
3_____
passive
evocative
active
Active genotype-environmental correlation is also known as ______ and occurs when kids seek out experiences that are consistent with their genetic predispositions,
niche-picking
In contrast to critical periods, _____ periods are more flexible and longer in duration.
sensitive
Birth defects are caused by many factors. PKU is due to the presence of a pair of ________.
recessive genes
Down Syndrome is caused by
an extra 21st chromosome
_____ Syndrome is caused by the presence of two or more X chromosomes along with a single Y chromosome.
Kleinfelter
_____ Syndrome is caused by a chromosomal deletion.
Prader-Willi
The critical period for teratogens varies from organ to organ, but, overall, exposure during the _____ stage is most likely to cause structural abnormalities.
embryonic
Alcohol consumption by a pregnant woman can cause _______, which encompasses a range of conditions that involves largely irreversible, physical, behavioral, and cognitive impairments.
fetal alcohol spectrum disorder (FASD)
Prenatal malnutrition is associated with a number of abnormalities, with severe ______ deficiency during the _____ trimester being especially detrimental for the developing brain.
protein
third
Prolonged _____ during the birth process can result in delayed motor and cognitive development, ID, and in severe cases, cerebral palsy.
anoxia
____ use in pregnant women increases the risk for spontaneous abortion and still birth, SIDS, low birthweight, an exaggerated startle response, and developmental delays.
