Wagner 'SOP' (improved) Model (15,16) Flashcards
What is re-acquisition, how does the RWM fail to explain this?
Re-acquisation - when after a US is extinguished, positive associative learning/conditioning is quicker than if CS was fully neutral
RWM predicts that CS would drop to 0 or even be negative, so learning should be the same or even slower. however learning about the CS is quicker
Spontaneous recovery is the _________, after some time, of a response that had been ________. RWM fails to account for this as it predicts what?
spontaneous recovery = reappearance of a response that had been extinguished.
RWM says that learning should have to occur for this to happen, which is not the reality
Wagner’s ‘SOP’ model stands for ________ _________ _________ or _________ _________ __________.
either
Standard operating procedure
or
sometimes opponent processes
The ‘SOP’ is an improvement on the RWM, as it explains everything the RWM model does, as well as what 2 main additional things, that the RWM failed to explain?
Latent Inhibition
One-trial overshadwing
Despite its improvements, the ‘SOP’ still fails to explain what 4 main things?
Extinction of pavlovian inhibitors
Downshift unblocking
spontaneous recovery
re-acquisition
What year did Wagner publish the ‘SOP’ model?
A 1966
B 1971
C1982
D1981
D 1981
Miller described the RWM as ____-_____, where the change in associative strength is computed after _____ _____, whereas the ‘SOP’ model operates more _________ in ____ _____.
RWM = trial wise, delta V calculated after each trial
Whereas ‘SOP’ operates more dynamically in real time
The ‘SOP’ can be described as elemental, what does this refer to?
Events like stimuli, are not stored as intact still images/photographs, but instead of divisible elements and representations.
Hebb’s law argues that cells that ______ _______, ______ ________
cells that wire together, fire together
Hebb’s law in terms of learning fails to explain the ________ of learning, as well as phenomena like ________.
fails to explain asymptote of learning
as well as blocking
Hebb’s law/ Konorski problem also implies that ______ and _________ conditioning would produce the same effect, simply because they occur __________.
Problem is that their idea suggest that forward and backward conditioning would produce the same effect, because they occur together
Wagner’s ‘SOP’ model can be thought of like Hebb’s model but with what difference?
A One main activity state
B Two different activity states
C Unlimited activity states
D No activity states
B Two different activity states
The ‘SOP’ model argues that Once a stimuli becomes activated, the stimuli nodes have 2 main states.
A1 is a state of high ______ and _________, however the stimulus node doesn’t ______ here for long, and A1 has _______ capacity
After the node in A1 state _____ it moves to A2, which is weaker. The A2 state is essentially ________ attention or a memory ______. It has a larger ______ than A1.
Two states of activity when CS/US are presented
A1 = high attention and perception of stimuli, However stimulus cannot stay here long, and A1 has limited capacity
A2 = after A1 state node decays, moved to A2. A2 state = peripheral attention or memory trace. Not in focal point. However larger capacity7 than A1.
There is also a third state called the _______ state, or ‘I’. This is when the stimulus node is not in our ______ at all, either before ________. or after it leaves
Inactive state (I), when stimulus node not in our attention. Either prior to activation or after it leaves A2.
A1 has a _____ capacity, whereas A2 and Inactive have an ________ capacity.
A1 = limited capacity
A2, I = unlimited capacity
