What three concepts describe how behaviours are learned, unlearned, and potentially re-emerge?
Acquisition, extinction and spontaneous recovery.
Describe the concept of acquisition.
-initial stage of learning when an organism learns to associate two stimuli
-when an organism learns to connect a neutral stimulus and an unconditioned stimulus
-neutral stimulus begins to elicit the conditioned response, and eventually the neutral stimulus becomes a conditioned stimulus capable of eliciting the conditioned response by itself
Describe the concept of extinction.
-decrease in the conditioned response when the
unconditioned stimulus is no longer presented with the conditioned stimulus.
-When presented with the conditioned stimulus alone, the dog, cat, or other organism would show a weaker and weaker response, and finally no response. In classical conditioning terms, there is a gradual weakening and disappearance of the conditioned response.
Describe the concept of spontaneous recovery.
-the return of a previously extinguished conditioned response following a rest period
Define stimulus generalization.
Process by which the CR is observed even though the CS is slightly different from the original one used during acquisition
Define stimulus discrimination.
Capacity to distinguish between similar but
distinct stimuli.
Define habituation.
Repeated or prolonged exposure to a stimulus
results in a gradual reduction in responsing.
How did this affect psychology?
-John B.Watson influenced by Pavlov
-great thing for behaviourism
-goal of john watson: if ppl coming into the world as blank slate then we can push them into smt/ shape who they are/control ppl
What was the research that John Watson did?
The Little Albert Study
1. Presented with neutral stimuli (rabbit, dog, cotton wool, a white rat etc).
2. Watson then paired these with a loud sound every time Little Albert touched the stimulus that caused him
to feel fear.
3. After repeated pairings, Little Albert became fearful of the stimulus alone.
- Little Albert demonstrated stimulus generalization—he became afraid of other furry things: a rabbit, a furry coat, and even a Santa Claus mask
-Emotions could become conditioned responses
What is a more ethical study that was done?
Mary Cover Jones: a study with three-year- old Peter, who already showed a fear of rabbits
* Successfully eliminates the fear response through conditioning
* Precursor to behavioral therapy
Are certain things easier to condition?
clown phobia, spiders, love, vomiting.
Are there evolutionary elements of classical conditioning?
yes! adaptive behaviours allow us to survive.
Define biological preparedness.
Propensity (an inclination or natural tendency to behave in a particular way) for learning particular kinds
of associations over others
Give an example of taste aversion.
For example, rats do not throw up so they can simply die if they digest the wrong foods. So they develop taste aversion (strong dislike or disinclination) towards things that are bad for them) - higher awareness.
Is everything we learn based on reflexes?
No. for example, if the teacher asks a question will we all raise our hands, no! we learn through reward and punishment through social acceptance.
Define operant conditioning.
-organisms learn to associate a behaviour and its consequence. A pleasant consequence makes that behaviour more likely to be repeated in the future.
-Behaviour that an organism produces that has some impact on the environment; coined by B.F. Skinner Demonstrated using the operant chamber or Skinner Box
What is the law of effect?
first proposed by psychologist Edward Thorndike… Behaviors that are followed by consequences that are satisfying to the organism are more likely to be repeated, and behaviors that are followed by unpleasant consequences are less likely to be repeated
When we talk about operand conditioning, it’s reinforcement and punishment. For the example of the rat pressing the lever to get food, does it initially know?
No, not at all. It knows by the off chance.
In operant conditioning, what do positive and negative mean?
+: you are adding something
-: taking something away
In operant conditioning, what does reinforcement and punishment mean?
Reinforcement: increasing a behaviour
Punishment: decreasing a behaviour
