RUTGERS PSYCHOLOGY FINAL EXAM 2024 QUESTIONS WITH
COMPLETE VERIFIED ANSWERS GRADED A++
What is an operational definition?
A worded statement of the exact procedures used in a research study
what is a case study
study of one individual in great detail
What is a survey method
Asking people questions about their thoughts, feelings, desires, and actions and
recording their answers
What is a observational study
Describes and measures people and/or animals behavior systematically
What is a correlational study
measures strength and direction of relationship between two variables
What is an experimental study
method in which one researches manipulates one variable and measures the effects of
that change on another variable
What is random sampling
Where a researcher randomly selects a subset of participants from a population
What is a positive correlation
suggests that variables change in the same direction
What is a negative correlation
suggests that variables change in opposite directions
Does correlation indicate causation
NO- Instead of A causing B, B could cause A, or C could be causing both A and B
What is random assignment
Procedure where every participant has an equal chance of being either the
experimental or control group
What is the independent variable
What is manipulated by experimenter
,What is the dependent variable
outcome that depends on other factors
What is the experimental control
Where researchers make sure that no factors other than the independent variable are
changing and thus could affect the dependent variable
What is the confounding variable
variable that is potentially responsible for the results, but is not the variable of interest
(the independent variable)
What is generalizability (regarding experiments)
A measure of how useful the results of a study are for a broader group of people or
situations
What does a myelin sheath do
Myelin sheath help speed neural impulses and cover axons of some neurons
What is an action potential
electrical impulse that travels from the cell body down to the end of the axon
What is the synapse
junction between two neurons (messages are transmitted across synapse via
transmitters)
What are neurotransmitters
Chemical messengers that facilitate communication between neurons
What do endorphins do
Involved in reducing pain and promoting pleasure
What does dopamine do
involved with voluntary movement, reward, learning, and memory
What does seretonin do?
involved in sleep, appetite, and mood
What is epinephrine involved in
involved in stress response
What is an agonist
Increase activity of a neurotransmitter
What is antagonist
, Decrease activity of a neurotransmitter
Sympathetic nervous system
Increases physiological arousal (stress)
parasympthetic nervous system
Decreases physiological arousal (stress)
What does the endocrine system do
secretes hormones, regulates bodily processes
what does the pitutary gland do?
Controls other glands in the body "master gland"
What do adrenal glands do?
regulates circadian rhythm and also produce epinephrine
what is an electroencephalogram (EEG)
Detects electrical activity of neurons in particular regions of the brain. Assesses function
but does not produce image
what is a functional MRI (FMRI)
Uses MRI to measure relative activity of various brain areas. Assesses function and
produces image.
What is the brainstem?
Controls involuntary movements
What is the amygdala
controls emotions such as fear and anger
What is the hippocampus?
Enables formation of new memories "gateway to memory"
What does the frontal lobe control?
at front of brain. involved in planning, creative thinking, and personality. Contains
broca's areas (involved with speech production) and motor cortex
What does the parietal lobe control?
at top of brain, contains somatosensory cortex
What does the occiptal lobe control?
in back of head contains visual cortex which processes visual signals
What does the temporal lobe control?
