Behavior-Chapter 4
Introduction to Learning and Behavior-Chapter 4 Vocab
| Term | Definition |
|---|---|
| Acquisition | The process of developing and strengthening a conditioned response through repeated pairings of an NS (or CS) with a US |
| Blocking | The phenomenon whereby the presence of an established CS interferes with conditioning of a new CS |
| Compound Stimulus | A complex stimulus that consists of the simultaneous presentation of two or more individual stimuli |
| Disinhibition | The sudden recovery of a response during an extinction procedure when a novel stimulus is introduced |
| Experimental neurosis | An experimentally produced disorder in which animals exposed to unpredictable events develop neurotic-like symptoms |
| External inhibition | A decrease in the strength of the conditioned response due to the presentation of a novel stimulus at the same time as the conditioned stimulus |
| Extinction | The process whereby a conditioned response can be weakened or eliminated when the CS is repeatebly presented in the absence of the US; also, the procedure whereby this happens, namely, the repeated presentation of the CS in the absence of the US |
| Higher-order conditioning | The process whereby a stimulus that is associated with a CS also becomes a CS |
| Latent inhibition | The phenomenon whereby a familiar stimulus is more difficult to condition as a CS is likely to be followed by the US with which it is associated |
| Occasion setting | A procedure in which a stimulus (known as an occasion setter) signals that a CS is likely to be followed by the US with which it is associated |
| Overshadowing | The phenomenon whereby the most salient member of a compound stimulus is more readily conditioned as a CS and thereby interferes with conditioning of the less salient member |
| Pseudoconditioning | A situation in which an elicited response that appears to be a CR is actually the result of sensitization rather than conditioning |
| Semantic generalization | The generalization of a conditioned response to verbal stimuli that are similar in meaning to the CS |
| Sensory preconditioning | In this phenomenon, when one stimulus is conditioned as a CS, another stimulus with which it was previously associated can also become a CS |
| Spontaneous recovery | The reappearance of a conditioned response following a rest period after extinction |
| Stimulus discrimination | The tendency for a response to be elicited by one stimulus and not another |
| Stimulus generalization | The tendency for a CR to occur in the presence of a stimulus that is similar to the CS |
| Temporal conditioning | A form of classical conditioning in which the CS is the passage of time |
| US revaluation | A process that involves the postconditioning presentation of the US at a different level of intensity, thereby altering the strength of response to the previously conditioned CS. |
