Classical and Operant Conditioning: Reflexes, Instincts, and Learning Processes, Lecture notes of Psychology

An overview of classical and operant conditioning, focusing on reflexes, instincts, and associative learning. Topics include unconditioned and conditioned stimuli, classical conditioning processes, and operant conditioning principles. The text also discusses the role of timing, spontaneous recovery, and stimulus discrimination in conditioning.

Reflexes are a motor or neural reaction to a specific stimulus in the
environment.
Reflexes involve more activity of specific body parts
Instincts are innate behaviors that are triggered by a broader range of
events, such as aging and the change of seasons
Reflexes and Instincts help an organism adapt to its environment and does
not have to be learned;learning is a relatively permanent change in
behavior or knowledge that results from experience
Associative learning occurs when an organism makes connections
between stimuli or events that occur together in the environment.
Associative learning is central to all three basic learning processes
discussed in this chapter; classical conditioning tends to involve
unconscious processes, operant conditioning tends to involve conscious
processes, and observational learning adds social and cognitive layers to
all the basic associative processes, both conscious and unconscious.In
classical conditioning, organisms learn to associate events or stimuli—that
repeatedly happen together. Observational learning extends the effective
range of both classical and operant conditioning. Observational learning is
the process of watching others and then imitating what they do. Humans
and other animals comes from observational learning.

Unconditioned stimulus is a stimulus that elicits a reflexive response in an
organism. Unconditioned response is a natural (unlearned) reaction to a
given stimulus. In classical conditioning, a neutral stimulus is presented
immediately before an unconditioned stimulus
Neutral stimulus is a stimulus that does not naturally elicit a response.
The conditioned stimulus is a stimulus that elicits a response after
repeatedly being paired with an unconditioned stimulus. Pairing a new
neutral stimulus with the conditioned stimulus is called higher-order
conditioning, or second-order conditioning. Classical conditioning also
applies to humans, even babies. In classical conditioning, the initial period
of learning is known as acquisition, which is when an organism learns to
connect a neutral stimulus and an unconditioned stimulus. During
acquisition, the neutral stimulus begins to elicit the conditioned response,

6. Unconditioned stimulus is a stimulus that elicits a reflexive response in an organism. Unconditioned response is a natural (unlearned) reaction to a given stimulus. In classical conditioning, a neutral stimulus is presented immediately before an unconditioned stimulus Neutral stimulus is a stimulus that does not naturally elicit a response. The conditioned stimulus is a stimulus that elicits a response after repeatedly being paired with an unconditioned stimulus. Pairing a new neutral stimulus with the conditioned stimulus is called higher-order conditioning, or second-order conditioning. Classical conditioning also applies to humans, even babies. In classical conditioning, the initial period of learning is known as acquisition, which is when an organism learns to connect a neutral stimulus and an unconditioned stimulus. During acquisition, the 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.Timing is important for conditioning to occur.Spontaneous recovery is the return of a previously extinguished conditioned response following a rest period. Acquisition and extinction involve the strengthening and weakening of a learned association.Two other learning processes are stimulus discrimination and stimulus generalization and they are involved in distinguishing which stimuli will trigger the learned association. Stimulus discrimination is when an organism learns to respond differently to various stimuli that are similar. Stimulus generalization is when an organism demonstrates the conditioned response to stimuli that are similar to the condition stimulus. Classical conditioning can lead to habituation. Habituation occurs when we learn not to respond to a stimulus that is presented repeatedly without change.As the stimulus occurs over and over, we learn not to focus our attention on it. John B. Watson is the founder of behaviorism. Behaviorism is a school of thought that arose during the first part of the 20th century, which incorporates elements of Pavlov’s classical conditioning.

6. The second type of associative learning is operant conditioning.In operant conditioning, organisms learn to associate a behavior and its consequence A pleasant consequence makes that behavior more likely to be repeated in the future. The law of effect are 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. In operant conditioning, positive and negative do not mean good and bad. Instead, positive means you are adding something, and negative means you are taking something away. Reinforcement means you are increasing a behavior, and punishment means you are decreasing a behavior. Reinforcement can be positive or negative, and punishment can also be positive or negative. All reinforcers increase the likelihood of a behavioral response. All punishers decrease the likelihood of a behavioral response. Positive reinforcement is something that is added to increase the likelihood of a behavior. Positive punishment is something that is added to decrease the likelihood of a behavior. Negative Reinforcement is something that is

fictional characters or real people who demonstrate behaviors in books, movies, television shows, video games, or Internet sources) There are specific steps in modeling attention, retention, reproduction, and motivation. First, you must be focused on what the model is doing. Next, you must be able to retain, or remember, what you observed; this is retention. Then, you must be able to perform the behavior that you observed and committed to memory; this is reproduction. Finally, you must have motivation. Vicarious reinforcement is if you saw that the model was reinforced for her behavior, you will be more motivated to copy her. Vicarious punishment is hand, if you observed the model being punished, you would be less motivated to copy her.
