lifespan Flashcards
In terms of heredity what are the three gene combinations?
-Single gene-pair inheritance characteristic. A single pair of genes (two recessive genes or one recessive and one dominant gene).
-Sex-linked inheritance occurs when a characteristic is influenced by a gene on one of the sex chromosomes, most often the X chromosome.
-polygenic inheritance occurs when a characteristic is influenced by multiple genes. Most characteristics – e.g., height, weight, hair color, intelligence, and susceptibility to cancer – are polygenic.
What is a phenotype?
Observed characteristics which is a combination of nurture and nature, e.g. height.
What is a genotype?
Genetic inheritance?
Explain how height are a combination of genotype and phenotype.
well, heritability is the variability in phenotype(observed height, e.g. 6 feet), but say about 80 percent is due to genetics, and 20 percent is due to environment, e.g. good eats.
What is heritability?
which variability in phenotype in a given population is attributable to differences in genotype:
Explain heritability in intelligence
.7 for high economic families
but .1 for low economic families
explain critical and sensitive period in terms of environmental influence?
Critical period is a limited period of time when exposure to certain environmental events is necessary for development to occur.
sensitive period is usually longer than a critical period and is a period of time when it’s optimal (but not necessary) for certain environmental events to occur.
Explain by Bronfenbrenner’s ecological theory in terms of
-micro
-meso
-macro
-exo
chronosystem
-Microsystem is the child’s immediate environment and includes the child’s relationships with parents, siblings, friends, and others at home, school, and church.
-The mesosystem involves interactions between different microsystems in the child’s life. For example, open communication between a child’s parents and teachers provides consistency across both environments.
-exosystem It incorporates other formal and informal social structures. While not directly interacting with the child, the exosystem still influences the microsystems. e.g politics, finances, world events.
-macrosystem established society and culture in which the child is developing.
-Chronosystem is The chronosystem relates to shifts and transitions over the child’s lifetime.
e.g. environmental shifts.
What is fetal programming?
environmental events in utero during sensitive windows of development can have permanent and long-lasting effects.
e.g. undernutrition during prenatal development is predictive of an increased risk for coronary heart disease and type 2 diabetes in adulthood
What is the average genetic heritability for intelligence?
How does it change as we age?
-overall .5
.2 to start moves to .8 in adulthood and back to .6 as seniors
What is behaviour genetics?
it is the study of how genetics effects behavioral psychological traits.
What’s the deal with twin studies and equal environment assumption?
well monozygotic twins have a higher correlation for intelligence than fraternal. however, mono also have a more homogenous environment which kinda makes the twin studies invalid
What are the findings of adoption studies?
Higher correlation due to genetic than environmental influence.
What are twin adoption studies and why are they the best?
Well you can basically have the same genetic template raised in a separate environment to show the difference between nature vs. nurture.
What is the Genotype-Environment Correlation?
that a person’s genetic make-up not only affects a person’s characteristics directly but also indirectly by influencing the environments the person is exposed to.
What is Passive genotype-environment correlation?
children inherit genes from their parents that predispose them to have certain characteristics and are exposed to environments by their parents that support the development of those characteristics.
For example, the children of sociable parents are likely to be genetically predisposed to being sociable, and their parents will provide them with many opportunities to participate in social activities.
What is Evocative genotype-environment correlation?
-child’s genetic make-up evokes certain kinds of reactions from parents and other people that reinforce the child’s genetic make-up.
-A sociable child will react to others in ways that encourage them to respond to the child in socially reinforcing ways.
What is Active genotype-environment correlation?
niche-picking and occurs when children actively seek experiences that “fit” their genetic predispositions?
How do the three genotype-environment correlations changes over time?
When you are little you are passive then you get noticed then evocative then niche
Explain Gottesman reaction range and canalization?
Reaction range for certain traits that determine how people respond to environmental influences.
-canalization means that the range is limited regardless of environmental influences. eg. IQ
What is Dynamic Systems Theory (DST)?
In other words it’s complex
nature and nurture to be essential for development. It’s based on the assumption that development is not simply the result of physical maturation but, instead, “is a complex process that involves the interaction of biology, environment, how we control ourselves and interact with others, and how we think about, or represent, our experiences in our minds
What is epigenetics?
-the study of changes in organisms brought about by modification of gene expression rather than by alteration of the genetic code in the form of DNA.
-for example diet, environmental pollutants, and child abuse can all influence genetic expression.

-Females with this disorder don’t develop secondary sex characteristics and are infertile,
What is Rett syndome disorder?
-X-linked dominant disorder
-caused by mutations in the MECP2 gene and almost exclusively affects females.
-Infants with this disorder appear to develop normally during the first 6 to 18 months of life but then develop characteristic symptoms that include slowed head and brain growth, loss of speech and motor skills, abnormal hand movements, sleep disturbances, breathing abnormalities, and seizures.
-Children with Rett syndrome may also have autistic-like symptoms (e.g., deficits in social interactions) during the early stages of the disorder.
What is down syndrome?
autosomal disorder, which means it’s caused by an abnormality on a chromosome that’s not a sex chromosome.
type 1—trisomy 21, which is also referred to as regular and standard trisomy 21 and accounts for about 95% of all cases of Down syndrome.
- It’s due to the presence of an extra 21 chromosome in all cells of the body so that each cell contains 47 (instead of the usual 46) chromosomes.
-Mosaic trisomy 21 accounts for about 1% of all cases. It occurs when only some cells in the body contain an extra 21 chromosome.
-Translocation trisomy 21 accounts for about 4% of all cases. It is characterized by 46 chromosomes in all cells of the body with some cells having a full or partial chromosome 21 attached (translocated) to another chromosome, most often chromosome 14.
What are the causes of down syndrome?
- genetic heritability
- age-over 30

Tell me about Huntington’s disease?
-Autosomal dominant disorder, which means it is caused by a single autosomal dominant gene.
What is Phenylketonuria (PKU) caused by?
-Caused by two autosomal recessive genes
-when a biological child inherits the PKU gene from both parents and, consequently, is homozygous with regard to that gene. When both parents are carriers of the recessive gene (i.e., they each have only one recessive gene for PKU), each of their biological children has a 25% chance of having the disease.
-A person with PKU is unable to adequately metabolize the amino acid phenylalanine.
-Consequently, treatment is a diet low in phenylalanine that begins soon after birth and is maintained through the lifespan (e.g., no milk, cheese, meat, fish, or eggs).
-Without treatment, the build-up of phenylalanine causes intellectual disability, hyperactivity, seizures, eczema, a musty body odor, hypopigmentation, and stunted growth.

- Partial fetal alcohol syndrome (pFAS) has the same central nervous system dysfunction as FAS, but facial anomalies are less severe and retarded physical growth may or may not be present.
- Alcohol-related neurodevelopmental disorder (ARND) involves central nervous system dysfunction without prominent facial anomalies, retarded physical growth, or physical defects.
- Alcohol-related birth defects (ARBD) is characterized by heart, kidney, vision, and other physical defects without other prominent symptoms.

What are Piaget’s 3 stages of moral development? Give as much info as you can.
(a) Premoral Stage:
0-5
(b) Heteronomous Stage: 5-6
rules can’t be changed they judge life by consequences. e.g. accident or purpose it don’t matter its what is the effect.
(c) Autonomous Stage: starts at 10 or 11. believe rules can be changed. Intent is important.

- it’s universal
- everyone goes through the stages in the same sequential order
- based upon cognitive development and perspective taking.
What are kholberg’s stages of moral development?
Level 1: Preconventional Morality:
(a) the punishment and obedience stage
(b) the instrumental hedonism stage, behavior depends on rewards or satisfies the person’s needs.
Level 2: Conventional Morality: The two stages of this level are (a) the “good boy/good girl” stage, during which the acceptability of a behavior depends on socially approved of or liked
(b) the law and order orientation stage, during which behavior depends on laws and rules that have been established by legitimate authorities.
Level 3: Postconventional Morality: The two stages of this level are (a) the morality of contract, individual rights, and democratically accepted laws, during which the acceptability of a behavior is whether or not it’s consistent with democratically chosen laws, and (b) the morality of individual principles of conscience, during which the acceptability of a behavior is whether or not it’s consistent with broad, universally applicable general principles (e.g., justice, fairness).
criticisms of Kohlberg’s theory
- does not take into kids’ cognitive development.
- not culturally universal
- studies only done on men
- don’t accurately reflect reality.
