6-9 Flashcards
What is the general definition of learning?
Any relatively durable change in behaviour or knowledge due to experience
What specific type of learning is referred to as conditioning?
Learning connections between events that occur in an organism’s environment
Define classical conditioning.
A type of learning where a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus
Who first described classical conditioning?
Ivan Pavlov
What is an unconditioned stimulus (UCS)?
A stimulus that evokes an unconditioned response without previous conditioning
What is an unconditioned response (UCR)?
An unlearned reaction to an unconditioned stimulus that occurs without previous conditioning
What is a conditioned stimulus (CS)?
A previously neutral stimulus that now evokes a conditioned response due to conditioning
What is a conditioned response (CR)?
A learned response to a conditioned stimulus due to conditioning
Differentiate between unconditioned association and conditioned association.
Unconditioned association is natural and unlearned, while conditioned association is established through pairing
What does Thorndike’s law of effect state?
When a response to a stimulus is associated with satisfying effects, the response is more likely to be repeated in that context
What is operant conditioning?
A form of learning in which responses come to be controlled by their consequences
What is the difference between primary and secondary reinforcers?
Primary reinforcers satisfy biological needs; secondary reinforcers acquire reinforcing qualities through association with primary reinforcers
What is the process of acquisition in conditioning?
The initial stage of learning
What is extinction in classical conditioning?
The gradual weakening and disappearance of a conditioned response tendency
What is spontaneous recovery?
The reappearance of an extinguished response after a period of nonexposure to the conditioned stimulus
What is the renewal effect in conditioning?
If acquisition occurs in one context and extinction in another, the responding will reappear when placed back in the original context
Define stimulus generalization.
When conditioning generalizes to stimuli that are similar to the original stimulus used to develop the conditioning
Define stimulus discrimination.
When an organism learns a response to a specific stimulus and does not respond the same way to new stimuli that are similar
What is continuous reinforcement?
When every single time a response is provided it is reinforced
What is intermittent reinforcement?
When a specific response is reinforced only some of the times it occurs
What is a fixed-ratio schedule?
The reinforcer is given after a fixed number of nonreinforced responses
