Psychology Exam 1
random assignment
Betty decided to conduct an experiment on the effectiveness of a new anti-anxiety pill. She decided that participants who had been diagnosed with anxiety would be in the treatment group and participants who had never been treated for anxiety would be the control group. Which aspect of proper research design did Betty ignore?
a confounding variable
An article headline claimed that "Drugs Cause Homelessness" due to a positive relationship found between homeless populations and drug use. Educated psychologists thought this might be flawed, because they thought unemployment was influencing both drug use and homelessness. This is an example of:
a measure of the strength of the relationship between individual differences in a given trait and individual genetic differences
A heritability coefficient is:
The placebo effect
A researcher would like to determine the effect of caffeine on memory. Participants are randomly assigned to receive a caffeine pill or a sugar pill. Both groups complete a recall task that assesses their memory. However, even those who received the sugar pill had a small increase in memory. This is likely due to:
Vision, motion tracking
what does the occipital lobe have control over?
Integration of sensory information; touch
what does the parietal lobe have control over?
sounds, smell
what does the temporal lobe have control over?
Somatic Nervous system, Autonomic Nervous System
what makes up the Peripheral Nervous System?
exam performance
Students who study for 7 hours over the course of a week will perform better than students who cram for 7 hours the night before the exam. The dependent variable in this hypothesis is:
method of studying (spaced or crammed)
Students who study for 7 hours over the course of a week will perform better than students who cram for 7 hours the night before the exam. The independent variable in this hypothesis is:
made up of the brain and spinal cord
The Central Nervous System is
Neurotransmitters
The chemical signals that travel from one neuron to another, enabling them to communicate with one another, are called:
External Validity
The degree to which a study ensures that potential findings apply to settings and samples other than the ones being studied refers to:
to conduct electrical signals that help cells communicate
The primary function of an axon is:
Magnetic Resonance Image (MRI)
To generate a structural image of the human brain, researchers typically use:
electroencephalogram (EEG)
To image electrical activity of neurons firing in the brain researchers use _________ which attaches electrodes to the outside of a person's head.
Longitudinal Fissure
What divides the cortex into the left and right cerebral hemispheres?
Process sensory info and controls voluntary movements
What does the Somatic Nervous System do
Problem solving, planning, coordination of speech
What does the frontal lobe have control over?
Corpus Callusum
What is the bundle of nerve fibers that connect left and right hemispheres?
a number that indicates the strength and direction of an association between variables
What is the correlation coefficient?
Fight or flight, mobilizing, control over involuntary actions
What is the sympathetic nervous system?
the laboratory experiment
What kind of research is traditionally considered to be the "gold standard" in psychology research?
Cranial Nerves, Spinal Nerves
What makes up the Somatic Nervous System:
must be determined by a review board established by the sponsoring institution
Whether or not a given study has the possibility of causing harm to participants:
Privacy
Which ethical guideline would a scientist be breaking if they videotaped children, without asking their guardians, while the children were taking a test in class?
A study should only be conducted if the study's benefits outweigh the risks
Which of the following is an example of an empirical question that could be tested using systematic observation?
Most psychological traits have a genetic component but nature also has the ability to change even supposedly "fixed" traits such as height
Which of the following sentences best describes current thinking on the nature-nurture debate?
Observations provide the basic data that allow scientists to track, tally, or otherwise organize information about the natural world.
Why is it beneficial for scientists to use systematic observation in order to acquire knowledge?
Informed Consent
____________ is important to obtain before starting a research study to ensure people know they are involved in the study, what will happen in the study, and understand they can choose to stop participating at any time.
It divides traits' determinants into two portions: genes and environments.
issue with the heritability coefficient?
Deception; Debriefed
Betty took part in a study where she was told the purpose was to further examine perceptual cognitive processes. Once the study was over, however, the researcher explained to her that the study's real purpose was to assess automaticity of stereotypes. This study is an example of research that used _________ in their methods to hide the true nature of the study. And we see that as a result, the researchers fully _________ participants afterwards.
Participant Demand
Blake is selected for a study on music preference and happiness. He thinks the experimenter's hypothesis is that people who listen to classical music are happier. As a result, Blake reports listening to classical music more often than he really does, as well as inflated scores on self-reported happiness. This is an example of
Correlational Design
Children's behavior on a playground is observed and later parents complete a questionnaire regarding home behavior of these same children. The researcher is interested in the relationship between aggressive displays with peers and aggressive behavior at home. This method would best be described as a:
Occipital Lobe
If you see a bird flying toward you this information is most likely processed in the:
confounding variables
In order for researchers to be able to say that Variable A causes Variable B, they must eliminate the possible influence of ________.

Informed consent to serve as a subject in research requires signing a document that states:

One of the best ways to answer questions associated with the nature-nurture debate is to complete twin studies, especially with __________ twins.
