Psychology Midterm 1-4
A study that aims to examine gender differences in visual perception would most likely use
which method? - ANS quasi-experimental
Which of the following statements best represents the behaviorist approach within the field of
psychology? - ANS It proposed that natural selection could help explain why humans behave
the way they do.
What is the purpose of an Institutional Review Board (IRB)? - ANS to ensure research meets
ethical standards
A psychologist is conducting a study on the effect of music on math ability. She hypothesizes
that participants who listen to classical music will perform better on a math test than those who
listen to pop music. She randomly assigns participants a music condition (classical or pop) and
then asks them to complete a timed measure of math ability. Which variable in her study is the
independent variable? - ANS music type
What is one advantage over surveys that case studies can provide? - ANS They generalize to
other people or settings.
Baz found a correlation of 0.56 between students' level of extraversion and the time they spent
participating in class discussion. How should they interpret this finding? - ANS Students with
high extraversion scores spent more time speaking.
In a study on emotions, participants are randomly assigned to watch either a happy or a sad
short-film and then asked to complete a puzzle while being timed. In this experiment, what is the
independent variable? - ANS the type of film the participants watched
Jacob wondered whether Floridians were more likely to return a lost wallet than New Yorkers.
So, he set up a camera and had a confederate drop her wallet in the middle of a busy street in
each city. Results indicated that Floridians were more likely to give the wallet back to the
confederate than New Yorkers. What type of method does this study employ? - ANS naturalistic
observation
Which of the following principles of ethical practice involves providing participants with
knowledge of the potential risks of a study before they agree to participate? - ANS informed
consent
Someone who designs the cockpits of planes so that he or she can easily be operated by pilots
could be described as - ANS a human factors psychologist.
, A psychologist who studies how people change as they age could be described as a: - ANS
developmental psychologist.
A psychologist who seeks to understand and enhance the quality of life for individuals and their
communities would most likely come from which of the following specialty areas in psychology?
- ANS community psychology
The structuralist technique of observations involves: - ANS a self-observation
* Psychology is defined as the ____. - ANS scientific study of behavior and mental processes
The chemical messengers that carry signals across the space between two neurons are known
as the: - ANS neurotransmitters.
The disease characterized by loss of myelin that results in a progressing inability to control the
body and respond to sensory information is called: - ANS multiple sclerosis.
The neuron that sends the signal at the synapse is known as the: - ANS presynaptic neuron.
A brain cell that provides information support functions and helps produce myelin is referred to
as - ANS a glial cell
The neuron that receives the signal at the synapse is known as the: - ANS postsynaptic
neuron.
Approximately how many synapses exist in the average human brain? - ANS 100 trillion
Approximately how many neurons can an individual neuron form a synapse with? - ANS 10,000
A fatty, waxy substance that insulates portions of some neurons in the nervous system is known
as - ANS myelin
The branch-like structure on the head of the neuron that receives incoming signals from other
neurons is known as the - ANS dendrite.
The charged particles that play an important role in the firing action of potentials in the nervous
system are known as - ANS ions
The part of a cell that contains the nucleus and its DNA is known as the: - ANS nucleus
The part of a cell that contains the DNA inside a cell body is known as the: - ANS nuleus
