Chapter 6 Flashcards
Habituation
The process whereby someone responds less strongly over time to a given stimulus represents of the simplest forms of learning, which is Habituation.
Stimulus
any event or object in the environment to which a organism responds
Classical Conditioning
form of learning in which animals come to respond to a previously neutral stimulus that had been paired with another stimulus that elicits an automatic response
Neutral Stimulus
No real reaction, usually since it’s a caused from something of past knowledge.
Unconditioned Stimulus (UCS)
(UCS) Stimulus that elicits an automatic response without prior conditioning
It’s unlearned behaviour
What kind of stimulus is flinching your eye to an oncoming ball to your face
UCS
Unconditioned Response (UCR)
(UCR) Automatic response to a nonneutral stimulus that does not need to be learned
The reflexive response to an unconditioned stimulus
UCR
Conditioned Response (CR)
(CR) A response previously associated with a nonneutral stimulus that is elicited by a neutral stimulus through conditioning
A response that is elicited by the conditioned stimulus
CR
Conditioned Stimulus (CS)
(CS) Initially neutral stimulus that comes to elicit a response due to association with an unconditioned stimulus
An initially neutral stimulus that comes to elicit a conditioned response after being paired with an unconditioned stimulus
CS
Two important components in classical conditioning and brief explanations
Timing of Events:
Must be short delay between the NS and rhe US for conditioning to occur
Sequence of Events:
The NS must be presented before th US for conditioning to occur
Three Phases of Classical Conditioning
Acquisition
Extinction
Spontaneous Recovery
Acquisition
Learning phase during which a conditioned response is established
Acquisition is the repeated pairing of UCS and CS, increasing the CR’s Strength
Backward conditioning
Which the UCS is presented before the CS—is extremely difficult to achieve
We see that as the CS and UCS pair over and over, the CR increases progressively in strength. The steepness of this curve varies depending how close together in time the CS and UCS are presented
The closer in time the pairing of CS and UCS, the faster learning occurs.
About a half second delay is typically the optimal pairing for learning. Longer delays usually decrease the speed and strength of organism’s response
Acquisition
Extinction
Elimination of a response that occurs when the CS is repeatedly presented without being followed by the US
Gradual reduction and eventual elimination of the conditioned response after the conditioned stimulus is presented repeatedly without the unconditioned stimulus
Extinction
Spontaneous Recovery
Sudden re-emergence of an extinct conditioned response after a delay following an extinction procedure
Renewal Effect
The reappearance of a conditioned response that had previously been extinguished in a novel setting.
A phenomenon in which a seemingly extinct CR reappears (Often in somewhat weaker form)
Spontaneous Recovery
Stimulus Generalization
Process in which conditioned stimuli that are similar, but not identical, to the original conditioned stimulus elicit a conditioned response
Stimulus Discrimination
the ability to distinguish between one stimulus and similar stimuli
Carla takes a new job as a bee keepr. On her first day she is stung by a bee. The bee sting is the ___
Carlas feeling of excruiciating pain to the bee sting is the ___
Now when carla sees a bee she becomes very fearful. The fear when she sees a bee is the ___
The bee has now become the ___
Carla’s fear is not just tied to seeing a bee. She becomes fearful anytime she sees a largish flyin insect. This is an example of ____
After a few days though she is no longer fearful of flying insects like flies and dragonflies; only to the stinging bees. This is an example of__
In order to keep her job Carla knows that she must keep working around bees. She finds that after a couple of weeks she is no longer afraid of bees. This is an example of____
After taking a month off of work from beekeping to travel the world, carla returns only to find she once again Is a little afraid of the bees. This is an example of ____
UCS
UCR
CR
CS
Stimulus generalization
Stimulus discrimination
Extinction
Spontaneous Recovery
Higher-Order Conditioning
Developing a conditioned response to a conditioned stimulus by virtue of its association with another conditioned stimulus
How do Organism develop Higher-Order Conditioning?
Organisms learn to develop conditioned associations to previously neutral stimulus that come to be associated with the original CS.
Latent Inhibition
A stimulus often experienced Alone may be resistant to conditioning
Conditioned compensatory response (CCR)
CR that is opposite of the UCR
Example: Drugs taken in same room
Cues in initiate defensive response (I.E. A CCR) which prepares body for drugs effect
Your body is used to its environement, so if you consume drugs in the same room often you’re likely to have you body prepare itself naturally better, however if you consume a high dosage somewhere new, like a hotel room. Then you might find that your body is not prepared as well and may suffer an overdose
The Law of Effect
Principle asserting that if a stimulus followed by a behaviour results in a reward, the stimulus Is more likely to give rise to the behaviour in the future.
Skinner Box
Small animal chamber constructed by B.F. Skinner to allow sustained periods of conditioning to be administered and behaviors to be recorded unsupervised
AKA an Operant chamber
Three Key concepts in Skinnerian psychology
Reinforcement, punishment, and discriminative stimulus.
Reinforcement
Outcome or consequence of a behavior that strengthens the probability of the behavior (Both have an increase in behavior)
Positive and Negative Reinforcement
The presentation of a stimulus (what we would usually think of as a pleasant stimulus) following a behavior that strengthens the probability of the behavior. (When a reward follows some behavior)
he removal of a stimulus (what we would usually think of as an unpleasant stimulus) following a behavior that strengthens the probability of the behavior. (When something unpleasant is removed after some behavior)
Positive =
Negative =
Reinforcement =
Punishment =
presentation of something
removal of something
Increase Behaviour
Decrease behaviour
Punishment
Outcome or consequence of a behaviour that weakens the probability of the behaviour (Reduction of behaviour)
Positive Punishment
Typically involves administering a stimulus that the organism wants to avoid, such as physical shock, or an unpleasant social outcome, such as laughing at someone
