2025 STRAIGHTERLINE PSY 101 ACTUAL EXAM QUESTIONS
WITH ANSWERS 2025/2026 GRADED A +
Psychology - A scientific discipline that studies behavior and mental processes.
Dependent variable - The factor in a formal experiment that is expected to vary in
response to changes in the independent variable.
Experimental group - Any group participating in an experiment that receives some
treatment or level of the independent variable.
Sample - A group of individuals taken from the larger population, ideally designed to be
representative of the whole.
Control group - The group in an experiment that is used for comparison purposes and
does not receive the treatment or condition being tested.
Placebo effect - Changes in behavior that occur simply due to people's expectations
and not due to actual treatment, such as when they feel better after being given a sugar
pill that has no active ingredient
Replication - Experiments that attempt to duplicate findings of a previous study in order
to confirm their validity and increase people's confidence in the results.
Random assignment - A method of assigning study participants to different groups by a
chance-based method (such as drawing names out of a hat, or random assignment by
computer).
Double-blind procedure - An experimental method where neither experimenter nor
participant know which was assigned to the experimental and control groups. This
prevents experimental bias.
Hypothesis - A precise prediction about some causal factor or other phenomenon that
can be tested in an experiment.
Theory - A tentative, broad explanation or prediction that is the starting point in
formulating a hypothesis.
Naturalistic observation - A research method in which behavior is simply recorded as it
happens in a natural setting.
Experimenter bias - The potential effect on study participants' behavior due to subtle,
unintentional influences exerted by the experimenter. Such influence can call the validity
of results into question
, Survey method - A research method that obtains information through the use of
questionnaires or interviews with subjects.
Informed consent - A document given to study participants in which they are informed of
the basic experimental procedures and told that they can withdraw at any time without
penalty. Participants read and sign the document to verify that they have understood it.
afferent neurons - Neurons that transmit messages from sense organs to the central
nervous system.
efferent neurons - Neurons that transmit messages from the central nervous system to
organs and muscles
somatic nervous system - The part of the peripheral nervous system that carries
messages from the sense organs to the central nervous system and from the central
nervous system to the skeletal muscles.
autonomic nervous system - The part of the peripheral nervous system that regulates
the actions of internal body organs, such as heartbeat.
sympathetic nervous system - The part of the autonomic nervous system that prepares
the body to respond to psychological or physical stress.
parasympathetic nervous system - The part of the autonomic nervous system that
promotes bodily maintenance and energy conservation and storage under nonstressful
conditions.
One advantage of naturalistic observation is that the researcher can examine behavior -
in a normal and realistic setting.
corpus callosum - Neurosurgeons can reduce the unbearable seizures some epileptics
experience by severing the
What was the main contribution of Hermann Ebbinghaus to psychology - He
demonstrated that carefully controlled experimentation can be conducted.
You have learned a list of 20 nonsense syllables. You are tested at 20 minutes, 1 hour,
10 hours, and 24 hours. If you fit Hermann Ebbinghaus's forgetting curve you will -
remember approximately the same number of syllables at 10 hours and 24 hours
