Document Summary
Process of acquiring a new learned or conditioned response is generally referred to as the acquisition phase of learning is gradual. Extinction: the gradual weakening and disappearance of a conditional response: conditioned stimulus would be presented, after several trials there would be no salivation in response to it (weakens gradually) Higher order conditioning: use an already conditional stimulus as an unconditional stimulus for a response to another stimulus you are trying to condition. Discrimination: generalization: graded conditional response often appears based on similarity of some stimulus to the conditional stimulus during conditioning, discrimination: responding is solely to the stimulus of interest. Intermittent reinforcement makes behaviour more resistant to extinction. Lecture 3: reinforcement and punishment reinforcer: stimulus that increases the frequency or probability of a behavior that it follows: positive (add something) & negative (taking away stimulus, primary (unlearned), secondary (conditioned/learned) reinforcers.
