|
What is the difference between probability and fuzzy logic?
|
probability is the degree to it happening and fuzzy logic is the degree to which they are ALL happening

What is functionalism?
|
it relies heavily on "hardware & software"; mental states are not just physical but functioning or operation of those physical states

radical and logical;

What is physicalism?
|
type identity theory (mental state), token identity theory (differences in reactions with same mental state)
|
|
|
What is dualism?
|
when one postulates both a physical brain that influences behavior to some degree and a non-physical mind that also influences behavior
|
|
|
What is monism?
|
the belief that the mental and physical consist of a single type of state or substance
|
|
|
What is a dendrite?
|
they send electrical signals through cells
|
|
|
What is an axon?
|
it gives direction of action potential
|
|
|
How does the electrochemical signal travel from one neuron to another neuron?
|
from the axon --> to the synaptic cleft --> to the dendrite --> to the cell body
|
|
|
What phrase characterizes Gestalt Psychology?

|
|
What does the Broca's Area do?
|
an area in the left frontal lobe that underlies language, and a deficit in production

|
What is fuzzy logic?
|
a method for translating uncertain knowledge into equivalent but precise linguistic representation and drawing conclusions on which to act.

|
recording of brain activity in response to a particular event

What is a wada test?
|
it finds which hemisphere has language dominantly

|
|
What is a cooling coil?
|
they freeze the brain to cells to fire
|
|
|
