PSYC 301 Exam Review
Behavioral genetics involves research is designed to
describe the genetic basis for behaviors.
If a fertilized egg begins to divide and multiply, and early in the process, the ball of cells splits into two, the woman will have
monozygotic twins.
Inter-rater reliability is established when
more than one observer looks at the same behavior and gets the same results.
Children who are victims of abuse can have many different long-term outcomes is an example of
multifinality.
When we have a negative correlation the value of one variable
increases as the value of the other variable decreases.
The American Academy of Pediatrics has recommended that
infants sleep close to their parents, but that they do not sleep in the same bed.
The unique advantage of experimental research is that
it can identify the causes of behavior.
The prefrontal cortex is responsible for
judgement, impulse control.
The Human Genome Project has the goal of
mapping all the human genes.
According to the text, what do educators and youth services workers need to have to support children and adolescents?
A strong foundation in the study of child development
Why do researchers want to discover which traits and behaviors are highly likely to develop from genetic input?
Because this will aid in the search for the specific genes responsible.
Which of the following statements about maternal smoking is true?
Maternal smoking has been associated with attention deficit disorder, conduct disorders, and learning disabilities.
What does developmental theory in non-Western cultures focus on?
The role of the individual in the context of the social group.
Which of the senses is least developed at birth?
Touch
One of the ways in which Vygotsky differs from Piaget in his view of how children learn is that
Vygotsky places more emphasis on the role of culture and the social world in cognitive development.
A conception that has one X and one Y chromosome in the 23rd position will become an individual who is
a male.
Fraternal twins are formed when
a mother's ovary releases two eggs during a menstrual cycle, and each is fertilized by a different sperm.
Children of mothers who are incarcerated are compared to children of mothers who reside with the children in their own homes on a number of cognitive outcomes. This is an example of
a natural or quasi-experiment.
A premature stereotype is
a stereotypically negative view of a premature infant that results in parents or others lowering their expectations for the child.
In the process of classical conditioning, the unconditioned stimulus is
a stimulus that naturally evokes an unconditioned response.
The embryonic stage of prenatal development is considered a critical period for development because
all major organs and structures are undergoing rapid development, and damage done at this point can be both severe and irreversible.
Reflexes
are involuntary patterned motor responses in infants.
You can have confidence in information that you find in scientific journals because
articles typically go through a peer review process.
The Apgar Scale is used to
assess the overall condition of a newborn at 1 minute and 5 minutes after birth.
The force that drives development can be
biological processes, environmental events, or a combination of both.
Professor Alsmith looks at changes in self-esteem across adolescence by measuring the self-esteem of 11 year olds, 13 year olds, 15 year olds, and 17 year olds, and comparing the results between the groups. This is an example of a
cross-sectional study.
Eleanor Gibson's research on infants and the visual cliff found that infants
can perceive depth, but do not show fear of the "drop off" until they can crawl.
Increased impulsivity and hyperactivity, as well as difficulty with organizing and integrating information, has been reported in children born to women who heavily used marijuana during their pregnancy. This is likely because
cannabis crosses through the placenta and alters the neurology in the prefrontal cortex, the part of the brain that handles higher cognitive functioning.
If a child younger than the age of about 4 or 5 were to have a large portion of their brain removed in a necessary surgery, their brains are plastic enough that
cells intended to serve one function could be turned into cells that serve another function.
When Piaget was conducting his research, he might present a story and then ask children questions about it. There were some questions he asked every child, but there also were questions that were specifically tied to the child's initial response. Piaget was using a
clinical interview.
One of the types of studies that has been used by behavioral genetics to determine the relative influence of genes and the environment is
comparisons of identical and fraternal twins.
The frontal lobe of the brain is primarily responsible for
complex thoughts, movement, language, and self-control.
The physical, cognitive, and socio-emotional domains of development
continually interact with each other.
The idea that biological maturation operates in interaction with the environment and the experiences it provides to children comes from
dynamic systems theory.
Maternal stress during pregnancy seems to have its greatest impact if it occurs
early in the prenatal period.
Canalization is the
extent that expression of a gene is influenced by the environment.
Abnormal facial features, small stature, a small head, cognitive deficits, and trouble controlling behavior and emotions are all characteristics associated with
fetal alcohol syndrome.
Freud would say that an adult who smokes heavily or one who constantly bites her nails is
fixated at the oral stage.
The most common cause of miscarriage is
genetic abnormalities.
The best research evidence today supports the idea that autism
has a genetic component and/or structural differences in the brain.
We know that infants can hear the voice of their mother before they are born because
newborns will suck on a pacifier to hear a recording of a story their mother read out loud during her pregnancy.
A severely restricted diet during pregnancy can lower a woman's basal metabolic rate, later putting her child at risk of
obesity.
If you read that a correlational study has found that children who participate in more extracurricular activities have higher self-esteem, you could conclude that
participation in extracurricular activities is associated with higher self-esteem.
A parent who suffers from a mental disorder may also provide a dysfunctional family environment for his or her children. In this case, we would describe the genes for the disorder as
passive.
Bandura's social cognitive theory added a third learning principle to classical and operant conditioning, which was that
people also can learn through imitation of behaviors they observe.
Because most human characteristics are complex, many genes act together to determine a trait. This is called
polygenic inheritance.
The scientific process cannot
prove a theory beyond a shadow of a doubt, but can provide evidence that supports or opposes the ideas in it.
Stage theories describe
qualitative changes.
Socioeconomic status (SES) is an important context for development because it is
related to the amount of resources that a family has.
If you wanted to encourage a child to eat a healthier diet, at first you might smile or not when the child was willing to take a small bite of a healthy food item on her plate. Then you might only smile and nod when the child took a full bite of the food. Then you might only respond when the child ate several bites, and finally only when the child finished the serving on her plate. You are changing this child's behavior through the process of
shaping.
A concordance rate allows us to look at the
similarity between relatives on a trait.
The best research on autism suggests
that it is caused by structural differences in the brain.
A child who has only heard English since birth loses the ability to distinguish sounds of another language because
the synapses associated with the sounds other language were pruned away.
Epigenetics is the term used to describe
the system by which genes can be turned on or off by environmental expression.
When we are interpreting the results of a study, it is important to remember that
the conclusions are generalizations that apply to groups of people, not to every single individual.
The two hemispheres of the brain are connected through
the corpus callosum.
Conditions such as depression, alcoholism, or schizophrenia have some genetic basis, but each results from
the interaction of many genes with environmental influences.
Independent variable is
the one that the researcher controls or manipulates in the experiment.
Dependent variable is
the outcome that is measured at the end of the experiment.
When the results of a study are statistically significant, it means that
the results are not likely to have occurred by chance.
The reason that a child who has only heard English since birth loses the ability to distinguish sounds in the Arabic language, is because
the synapses associated with the sounds in the Arabic language were not used and therefore pruned away.
Research that has measured the event-related potentials (ERPs) of infants found that infants paid more attention to a stimulus when
their caregivers reacted to the stimulus in a negative way than in a positive way.
A difference between a sexually transmitted bacterial infection such as Chlamydia or gonorrhea and a viral infection is
these bacterial infections can be treated and cured, but the viral infections are not curable.
Erik Erikson's psychosocial theory would suggest that the best way to help toddlers develop a sense of autonomy would be
to be patient and allow the child to do things on her own, even if she struggles a bit.
Behavioral genetics involves research designed
to describe the genetic basis for behaviors.
Freud believed that the key to healthy psychological functioning involved
uncovering thoughts in the unconscious mind that were associated with the psychological symptoms of the person's problem.
Brofenbrenner would say that it is important that we
understand the individual within all of the contexts that affect development.
One of the advantages of doing research by using observations is that
we can observe behavior as it naturally occurs.
The normal pruning that occurs in the prefrontal cortex is not complete until
well into adolescence and early adulthood.
The normal pruning that occurs in the prefrontal cortex (the portion of the brain that has to do with judgement and impulse control) is not complete until
well into adolescence or early adulthood.
Nature includes the influence of
what we bring to development as a result of our genetic inheritance.
