More novel stimuli result in ___ rapid conditioning |
More |
|
Latent-inhibition effect |
Previous exposure to a CS slows the acquisition of a CS-US relationship |
|
US preexposure effect |
Previous exposure to a US slows acquisition of a CR |
|
Contiguity predicts that a shorter delay results in ___ conditioning |
Stronger |
|
CS-US relevance/belongingness |
A relationship is learned faster if it is naturally related |
|
Higher order conditioning |
When a CS1 is strongly trained to a CR, pairing a CS1 with a CS2 will cause the CS2 to elicit the CR |
|
Sensory preconditioning |
When a CS1 and CS2 are already associated with one another, training a CS1 to elicit a CR will also train the CS2 to elicit the CR |
|
Stimulus substitution |
Treating the CS as a surrogate US. Emphasizes importance of the US and assumes the UR and CR are identical. |
|
Homeostasis |
Special case of stimulus substitution where the CR is only identical to the compensatory aspect of the UR |
|
S-R learning |
Thorndike. CS directly elicits CR. |
|
S-S learning |
Pavlov. CS triggers US which elicits the UR. |
|
Conditioned diminution of UR |
CS that predicts a US triggers compensatory reactions that reduce the intensity of the UR |
|
Blocking effect |
A CS1 strongly paired to a US will not allow a CS2 to be paired with the same US |
|
Overshadowing effect |
If a CS1 and CS2 are simultaneously paired with a US, but one is more salient, the other will be blocked |
|
Rescorla-Wagner model |
Predicts that the level of surprise of a US determines the effectiveness |
|
Problems with the RW model |
Predicts extinction of conditioned inhibition. Predicts the extinction is the reversal of acquisition. |
|
The comparator hypothesis |
Predicts that a CS elicits recall via both a direct and indirect pathway |
|
If the direct pathway is stronger than the indirect pathway |
Excitatory CR training |
|
If the direct pathway is weaker than the indirect pathway |
Inhibitory CS training |
|
Comparator hypothesis - Recovery from blocking |
If CS1 undergoes extinction, the indirect pathway between loses strength therefore allowing the direct pathway to dominate and cause a strong CR |
|
Comparator hypothesis - Conditioned inhibition |
If CS+ predicts US, but CS+CS- does not, CS- alone will not elicit any direct pathway and therefore will inhibit the CR |
|
Looking for action |
Attention a CS commands after it is trained and elicits a CR effortlessly |
|
Looking for learning |
Attention a CS commands when they aren't paired with anything yet (have much to be learned about) |
|
Looking for liking |
Attention a stimuli commands due to its emotional value |
|
Mackintosh attentional model |
Attention to CS increases with subsequent trials if it's already a good US predictor |
|
Pearce and Hall attentional model |
Attention to CS decreases with subsequent trials if it's already a good US predictor |
|
Temporal account of conditioning |
CS is learned faster if ISI is constant and ITI is longer or ISI is shorter and ITI is constant |
|
Thorndike vs. Skinner |
Thorndike = operant training is the result of new S-R relationships Skinner = operant training is the result of strengthened, existing S-R relationships |
|
Law of effect |
If the consequence (reinforcer) of a response is satisfying, the S-R relationship will be strengthened |
|
Response shaping |
Reinforcing behaviors that are succeaively closer to the operand response. Requires a clear desired response and division into appropriate steps |
|
Positive reinforcement |
Positive contingency, appetitive stimulus |
|
Punishment |
Positive contingency, aversive stimulus |
|
Negative reinforcement |
Negative contingency, aversive stimulus |
|
Ommision training |
Negative contingency, appetitive stimulus |
|
Variability vs. Stereotypy |
Rewarding behavior that has/has not been done before. Variable behavior can be successfully reinforced. |
|
Relevance/belongingness |
Operant response cannot be learned unless it is in some way natural to the subject |
|
Shifting reinforced quality/quantity |
Positive contrast encourages operant response while negative contrast discourages operant response |
|
Contiguity of response-reinforcer |
Shorter delay = stronger reinforcment |
|
Conditioned reinforcer |
Secondary reinforcment given when primary reinforcement cannot be to differentiate a behavior |
|
Marking |
Marking every response to make it more salient |
|
Adventitious reinforcement |
Belief that your behaviors are causing a reinforcment when they aren't |
|
Terminal responses |
Activities that increase when reinforcement is about to be delivered |
|
Interim responses |
Behaviors that increase in the middle of the ISI |
|
Learned-heplessness effect |
Impeded learning due to previous exposure to uncontrollable reinforcement |
|
Activity deficit hypothesis |
LHE is actually due to a learned conditioned response to freeze |
|
Attention deficit hypothesis |
LHE is due to the animal's unawareness of its own behavior after repeated shock |
|
Stimulus relations in escape |
Examines why escapable shock isn't nearly as bad for learning as inescapable shock |
