COGNITIVE SCIENCE SAMPLE. MIDTERM EXAM REVISION
QUESTIONS AND CORRECT ANSWERS (GRADED A+) (100%
GUARANTEE) (2024 UPDATE)
Mystery - ANSWER- An issue that we don't know how to approach
What is the most common answer to the mind/body problem? - ANSWER- Dualism
Dualism - ANSWER- The belief that mind and body are two distinct entities that interact
Introspection - ANSWER- Examination of one's own thoughts and feelings
New Mysterianism - ANSWER- A theory that consciousness will never be understood by
humans
Who discovered evolution? - ANSWER- Charles Darwin
What are the steps that explain evolution? - ANSWER- 1. Reproductive math - organisms have
offspring that have offspring, etc, it's a geometric sequence
#2 eventually they use too many resources so certain species' populations will dwindle
#3 it's not a lottery, biological advantages bias the sample so that some species have a greater
chance of reproducing
#4 if there's strong inheritance then any biasing advantages amplify over time (tall people have tall
kids who have tall kids, etc)
#5 best idea of all time! Future generations will be more equipped to survive
, What are the parts of the neuron? - ANSWER- cell body (soma), dendrites, axon, axon
terminals, myelin sheath, etc
Synapses - ANSWER- Gaps between neurons where signals are sent
Single Cell Recording - ANSWER- A technique by which the firing rate and pattern of a single
receptor cell can be measured in response to stimuli
Is there a specific neuron for each face? - ANSWER- No, there is a neuron for a single principal,
e.g. they fire more when eyebrows are bushier
EEGs and ERPs - ANSWER- Record electrical signals of firing neurons and measure changes
in electrical potential - high temporal resolution but poor spatial resolution
fMRI - ANSWER- A technique for revealing blood flow to the brain - blood flow increases as
activity increases
BOLD - ANSWER- Blood oxygen level detection
How does fMRI work? - ANSWER- Protons are spinning -> have an orientation, angular
momentum, causes precession as they slow down
Magnetic field -> axes of spinning protons will align themselves
Resonance imaging -> radiofrequency pulses change the axes and the magnetic field pulls them
back into orientation
Blood flow - the brain uses much oxygen that is delivered through hemoglobin in the blood,
increased activity -> oxygen depletion -> over-replenishes level of oxygen
