AP Psychology Unit 6: Learning Flashcards
Learning
The process of acquiring through experience new and relatively enduring information or behaviors
Habituation
Decreasing responsiveness with repeated exposure to stimulus
Associative Learning
Learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequence (as in operant conditioning)
Forms of Conditioning
- Classical conditioning
- Operant conditioning
Habituation vs. Sensory Adaptation
Habituation is a type of learning or relatively permanent change in behavior (lower response) that involves a reduced response as a result of repeated but not constant exposure.
Sensory adaptation is a perceptual phenomenon that occurs when the brain stops recognizing a constant and unchanging stimulus.
Stimulus
Any event or situation that evokes a response
Respondent Behavior
Behavior that occurs as an automatic response to some stimulus
Operant Behavior
Behavior that operates on the environment, producing consequences
Cognitive Learning
The acquisition of mental information, whether by observing events, by watching others, or through language
Observational Learning
A form of cognitive learning that lets us learn from other experiences
Classical Conditioning
A type of learning in which we link two or more stimuli; as a result, to illustrate with Pavlov’s classic experiment, the first stimulus comes to elicit behavior in anticipation of the second stimulus. Respondent/automatic behavior
Behaviorism
The view that psychology should (1) be an objective science that (2) studies behavior without reference to mental processes. Most research psychologists today agree with (1) but not with (2)
Pavlov’s Experiment
Measured the salivation of dogs in response to a beeping noise, which they were made to associate with food. He found that dogs can learn through classical conditioning, as they associated the sound of the buzzer with food.
Neutral Stimulus (NS)
In classical conditioning, a stimulus that elicits no response before conditioning
Unconditioned Response (UR)
In classical conditioning, an unlearned, naturally occurring response to an unconditioned stimulus (US)
Unconditioned Stimulus (US)
In classical conditioning, a stimulus that unconditionally - naturally and automatically - triggers an unconditioned response (UR)
Conditioned Response (CR)
In classical conditioning, a learned response to a previously neutral (but now conditioned ) stimulus
Conditioned Stimulus (CS)
In classical conditioning, an originally neutral stimulus that, after association with an unconditional stimulus (US), comes to trigger a conditioned response (CR)
Five Major Conditioning Processes
- Acquisition
- Extinction
- Spontaneous Recovery
- Generalization
- Discrimination
Acquisition
In classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response
Higher-Order Conditioning
A procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that a light predicts te tone and begin responding to the light alone. (Also called second-order conditioning)
Extinction
The diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced
Spontaneous Recovery
The reappearance, after a pause, of an extinguished conditioned response
Generalization
The tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses (In operant conditioning, generalization occurs when responses learned in one situation occur in other, similar situations)
Discrimination
In classical conditioning, the learned ability to distinguish between a conditioned stimulus and similar stimuli that do not signal an unconditioned stimulus. (In operant conditioning, the ability to distinguish responses that are reinforced from similar responses that are not reinforced)
Why are Pavlov’s Ideas Important?
- Found that many other responses to many other stimuli can be classically conditioned in many other organisms. It is a way that organisms can adapt to their environment
- He showed us how a process like learning can be studied objectively
How Can Pavlov’s Principles Be Applied Today?
- Drug cravings: Addicts are advised to steer away from people who they associate with drug highs
- Food cravings: Overweight people often have conditioned pleasure responses to sugary foods, making dieting difficult
- Immune responses: When a taste accompanies a drug that influences immune responses, the taste itself may cause an immune reaction
Little Albert
John B. Watson and his graduate assistant
Rosalie Rayner conditioned “Little Albert” to fear a white rat (neutral stimulus) after repeatedly experiencing a loud noise as the rat was presented. He grew to fear the rat and eventually generalized this fear to dogs and rabbits.
Operant Conditioning
A type of learning in which a behavior becomes more likely to recur if followed by a reinforcer or less likely to recur if followed by a punishment. Voluntary behavior.
Law of Effect
Thorndike’s principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely
Operant Chamber
In operant conditioning research, a chamber (also known as a Skinner box) containing a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animal’s rate of bar pressing or key pecking
Reinforcement
In operant conditioning, any event that strengthens the behavior it follows
Shaping
An operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior. Also called “reward by successive approximations”
Discriminative Stimulus
In operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement)
Positive Reinforcement
Increasing behaviors by presenting positive reinforcers. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response
Negative Reinforcement
Increasing behaviors by stopping or reducing aversive stimuli. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (Negative reinforcement is not punishment)
Primary Reinforcer
An innately reinforcing stimulus, such as one that satisfies a biological need (eating food, relieving pain)
