PSY 550 FINAL EXAM 2026 FINAL REVIEW
QUESTIONS ANSWERS BUNDLED PRACTICE
COLLECTION
◉ Belief Perseverance
Answer: tendency to stick to our initial beliefs even when evidence
contradicts them
◉ Six Principles of Scientific Thinking
Answer: Ruling out rival hypotheses, correlation versus causation,
falsifiability, replicability, extraordinary claims and Occam's Razor
◉ Descriptive approach
Answer: describing the world as it is
◉ Correlational Methods
Answer: uses statistics to explore
◉ Confounds
Answer: a factor that might effect the outcome of an experiment
after
,◉ Experimenter expectancy effect
Answer: researcher's hypothesis lead them to unintentionally bias a
study's outcome
◉ double-blind research design
Answer: neither the administrator nor the participant know the true
meaning of the experiment
◉ Measures of central tendency
Answer: mean, median, mode
◉ standard deviation
Answer: takes into account the highest and lowest scores
◉ normal curve
Answer: normal distribution that many human attributes and
behaviors, when measured take
◉ descriptive statistics
Answer: used to describe data
◉ Inferential statistics
,Answer: used to determine how much we can generalize findings
from our sample to the full population
◉ Statistical significance
Answer: measure of if the statistics are actually useable
◉ Reliability
Answer: consistency of measurement
◉ validity
Answer: extent to which a measure assesses what it intends to
measure
◉ ethical principles
Answer: informed consent and deception
◉ heuristics
Answer: mental short cut, rule of thumb
◉ System 1 thinking
Answer: fast, automatic, intuitive approach
, ◉ system 2 thinking
Answer: slower, analytical mode, where reason dominates
◉ Biological psychology
Answer: study of the neural substrates of behavior and mental
processes
◉ How are human brains and animal brains similar?
Answer: similarities in parts of brain, location or parts and
behaviors produced from certain parts
◉ How do human brains differ from animal brains?
Answer: much larger and more complicated, medulla and
cerebellum typically smaller, neocortex is larger
◉ Why use animals in research?
Answer: allows for use of move invasive procedures and provides a
simplified model
◉ parts of the neuron
Answer: cell body, dendrites, axons, synapse, synaptic cleft
◉ resting potential
