Classical Conditioning
Mechanisms Part 2
- SS and SR
Theories
stress the
importance of
the US and the
CS.
- Newer Models and Theories
- Rescorla-Wagner Model
- Determines the strength
of an association on a trial
by trial basis.
- Two factors
determine
associative
strength
- The
subject’s
expectation
- The
salience
of the US
- The
subject’s
expectation
- Mathematical
Model
- V=CS salience (US
salience-0)= % 2nd Trial:
V=CS salience(US
salience-%)=%%
%+%%=Trial 2 %
- V=CS salience (US
salience-0)= % 2nd Trial:
V=CS salience(US
salience-%)=%%
%+%%=Trial 2 %
- Six Rules
- Two factors
determine
associative
strength
- Determines the strength
of an association on a trial
by trial basis.
- Attentional Model
- Cocktail Party
Phenomenon
(all about
attention)
- Associations
formed on a
trial by trial
basis
- CS salience
and attention
to CS
determine
associations
- Procedures or
expereinces that
distract attention
from CS disrupt
learning
- No
difficulty
explaining
blocking
- Cocktail Party
Phenomenon
(all about
attention)
- Rate Estimation Theory
- Associations are formed based
on the temporal relationship
between the CS and US Interval
relative to the Trial Duration
- Scalar Expectancy theory
or Relative-Waiting-Time
Hypothesis
- The association strength is determine
or can be scaled by comparing the
CS-US Interval with the Trial Duration
The difference between the CS-US
interval and the Trial Duration is the
relative-waiting-time.
- The association strength is determine
or can be scaled by comparing the
CS-US Interval with the Trial Duration
The difference between the CS-US
interval and the Trial Duration is the
relative-waiting-time.
- Associations are formed based
on the temporal relationship
between the CS and US Interval
relative to the Trial Duration
- Comparator Hypothesis
- All stimuli within a
context develop some
association
- Strength is
determine by
comparing:
- The association
between the
target CS and the
US
- And other stimuli
(or comparators)
in the
environment
- The association
between the
target CS and the
US
- All stimuli within a
context develop some
association
- Connectionist Model
- Conceptual Nervous System
- Associations formed in neural networks
- Response comes from activation
across a network
- Spreading Activation Model
- Supported by Priming
- Spreading Activation Model
- The Delta Rule
- Conceptual Nervous System
- Behavior Systems Approach
- Stimuli
are not
neutral
- Stimuli have
biological
significance
- The strength of the
association is, in part,
determined by the CS-US
Relevance or Belongingness
- Stimuli
are not
neutral
- Rescorla-Wagner Model
