Gilbert Ryle
|
believes that their is no seperation between mind and the body; behaviorist, science of mind=science of behavior; mind and body not mutually exclusive
|
Gilbert Ryle
|
|
|
Descartes idea
|
The mind and body are 2 seperate entities; actions of the body are public, while actions of the mind are private, one can not know what another is thinking but can only analyze their actions based on your own behavior; 2 collateral histories 1 of mind one of body
-Gilbert Ryle BELIEVES IS FALSE |

|
|
|
Category Mistake
|
assuming that the university is in the same category as its subdivisions, instead of being composed of the subdivisions

|
Pavlov
|
behaviorist, studied conditioned reflexes through the salivary glands of dogs
|
Pavlov
|
|
|
unconditioned reflex
|
a reflex that requires no conditioning, ie. touching hot plate- pulling away
|
Pavlov
|
|
|
conditioned reflex
|
can be conditioned using an unconditioned reflex; root for understanding behavior, ex) light+food= salivation run many trials and light=salivation
|
Pavlov
|
|
|
secondary conditioned reflex
|
paired with conditioned reflex and never reinforced
ex) Light+tone(no food)=salivation then tone=salivation(though less) |
Pavlov
|
|
|
inhibitor
|
light and tone pairing continues w/o reinforcement after a time tone stops producing saliva then T+L=no salivation proving it to be inhibitory
|
Pavlov
|
|
|
inhibitor of the inhibitor
|
metronome paired with L+T at first no drops but always reinforced. M is slight inhibitor b/c L+M=6, but L+T+M=4 proving that m is inhibitor of T
|
Pavlov
|
|
|
equilibrium
|
after continued reinforcement w/ food M becomes a stimulator, so that L+M=10, meaning that we are back to the start neither more positive nor more negative
|
Pavlov
|
|
|
Norman Dixon
|
studied the conscious and preconscious aspects of thought
|
Dixon
|
|
|
2 systems of consciousness
|
the two systems of consciousness, one for transmission(fast unable to rest and think about transitory states), and the other for rep. in conscious experience(what we consider our thoughts)

Dixon
|
|
|
Studies in monkeys
|
if leminiscal pathways were destroyed they could still be roused by sound and touch; but if lem. left intact and the reticualar system was destroyed they remained in a coma, but showed cortical potential to auditory and somatosensory perception
|
Dixon
|
|
|
how 2 systems interact
|
they can work independantly, one can have consciousness w/o sensory input; one can also have sensory input w/o consciousness

priorities of consciousness
|
anything that is: changing, novel, or of emotional importance. unimportant info drops out of consciousness to make room for new info

using electrodes one can cause a patient to relive a memory; enters the same stream of consciousness. aware of 2 consciousness's past and present. irrelevant data lost but all other info retained.
|
Penfield and Roberts
|
|
|
interpretive responses
|
there is no recall of the past only an interpretation of the present(deja vu)
or a patient when applied w/ electrodes can feel strange and absurd. relationship of patient to environment is altered feels distance from events or proximity. |
Penfield and Roberts
|
|
|
real memory v. stimulated memory
|
real memory is a generalization while stim. memory is more vivid, as if reliving them. pain taste or smell is not represented in stim memories, andmost are unimportant memories
|
Penfield and Roberts
|
|
|
experiences w/ electrode do not go backwards or cross and stop when the electrode is removed it can not be voluntarily reactivated must be achieved through other mechanisms

|
patients were fully aware of present and adressed doctor instead of ppl in memory
|
d
|

|
problem of perception
|
perception may not requre activity in any particular cells, but learning must depend on changes in particular cells
|
Hebb
|
|
|
Learning
|
Changed pattern of brain conduction, resulting from experience and changes response potential. Simple(S->R).
|
Hebb
|
|
|
Simple learing proccess
|
S->R new connection is formed

|
|
Complex learning proccess
|
no resonse at time of learning, later a response shows learing did occur.
|
Hebb
|
|
|
What is a memory(hebb)
|
if changed pattern of conduction persists it's a memory, persistance is due to changed relation to particular pathways, and neurons, localized effect
|
Hebb
|
|
|
Cell assemmly theory(2)
|
when we proccess things it isnt always broken down to its base parts, it must be done 1st so we can learn to represent the whole directly
|
Hebb
|
|
|
when excitation reaches the cortex instead of having to be transmitted at once to a motor path or die out it may travel around the closed paths and continue to do so after the orig. signal is gone(hebb) makes delayed response and theoretical thought plausible(ready go)
|
a
|
Hebb
|
|
|
set go theory
|
the effect of the first must be held to till the 2nd is present. The 1st prepares the mind and makes the 2nd connection happen faster

chimpanzees deprivation/ learning processes
|
reared in dark did not develop the right way could not percieve sight b/c they were not capable even after being brought into the light

|
|
Deficit reactions
|
Emotion is a disruption of cell assembly. Even in the simple abscence of accustomed sensory input cell assemblies might b disrupted
|
Hebb

|
|
Hebbs test on Rats
|
hebb tested the difference between animals that had been raised in a poor environment v. animals that had been raised in a healthy environment. Rats raised in environments that lack sensory input were inferior to those raised in a hich stim. environment. This effect only occurs during the growth period(one group raised restricted then free as adults the other the opposite) 2nd group much better. Effects of early environment on intelligence irreversible. Visual even if unable to explore physically greatly enhances intelectual development

|
Hebbs expiriments on Dogs
|
(either raised in restricted enviro or given freedom of a pet). Those raised in restricted environment happy since they knew nothing else, though adults in those environments would be miserable. More extreme reactions. Dogs raised in restricted environments were untrainable, abnormal in personality, and difficult to describe social behavior. They also ignored pain. Less likely to form conditioned responses. Motivation and emotional ties of pain are functions of infant experience

use of words is important. ie smashing v. bumping. can create memory of object never seen or mentioned false info can either suplement or change a memory |
