PSYC 230 – UNC CHANON EXAM 1 QUESTIONS AND
VERIFIED ANSWERS LATEST VERSION
The mind cannot study itself, according to the early 1800s.
In the later 1800s—ANSWER I. Donders: RT for making decisions
II. Ebbinghaus-time forgetting process
ANSWER Watson & Skinner: behaviourism, early 1900s
In the middle of the 20th century, ANSWER PC and Al's, Chomsky, and
Neisser's first textbook
Neuropsychology: ANSWER investigates brain damage cases
Attention-ANSWER research accuracy and reaction time in experimental
psychology
ANSWER cell body, or soma; nucleus
Dendrites: ANSWER gathers information (receives), many
Axon-ANSWER transmits information, one of which is myelinated.
A signal is sent to neurones... A physical or chemical response
Sensory neurones, or receptor cells, respond to physical stimuli, rods, cones, or
touch.
Neurones that transmit impulses between other neurones, particularly as part of
a reflex arc, are known as interneurons.
, Dendrites allow sodium to permeate into the cell body. The answer is passive
current, which is powerful enough to cross a threshold before action current
starts.
Potential Action Steps: ANSWER a. Depolarisation causes sodium channels to
open.
a) Initiated by dendrites transferring sodium to the cell body
b. The opening of potassium channels (hyperpolarisation)
c. The resting potential of the axon is restored.
d. The sodium and potassium ion distribution is returned to normal by the ion
pump.
at rest... In comparison to the outside of the cell, the answer inside the cell is
negative.
When does the cell's interior feel the most positive? ANSWER The refractory
nature of Na+ channels
Why does myelination occur? ANSWER a. speeds up the transmission of
signals.
b. The ion channels cannot open where myelin is encircling the axons.
c. Grow as you grow.
High spatial resolution and accurate timing (temporal) are two advantages of
single cell recording.
Cons: Cell behaviour is more complex than the sum of its components, it is
difficult to identify individual cells and what causes their activity, and it is
typically not possible to do intrusive procedures on humans.
ERP-ANSWER advantages include noninvasiveness and accurate timing
(temporal).
Cons: needs a lot of trials and has terrible spatial
EEG-ANSWER broad states of consciousness, which are similar to ERP but
worse
ANSWER structure in MRI
