What Is Learning?
By the end of this section, you will be able to:
Explain how learned behaviours are different from instincts and reflexes
Recognize and define three basic forms of learning—classical conditioning, operant conditioning, and observational learning
Birds build nests and migrate as winter approaches. Infants suckle at their mother’s breast. Dogs shake water off wet fur. Salmon swim upstream to spawn, and spiders spin intricate webs. What do these seemingly unrelated behaviours have in common? They all are unlearned behaviours. Both instincts and reflexes are innate behaviours that organisms are born with. Reflexes are a motor or neural reaction to a specific stimulus in the environment. They tend to be simpler than instincts, involve the activity of specific body parts and systems (e.g., the knee-jerk reflex and the contraction of the pupil in bright light), and involve more primitive centers of the central nervous system (e.g., the spinal cord and the medulla).
In contrast, instincts are innate behaviours that are triggered by a broader range of events, such as ageing and the change of seasons. They are more complex patterns of behaviour, involve movement of the organism as a whole (e.g., sexual activity and migration), and involve higher brain centers.
Both reflexes and instincts help an organism adapt to its environment and do not have to be learned. For example, every healthy human baby has a sucking reflex, present at birth. Babies are born knowing how to suck on a nipple, whether artificial (from a bottle) or human. Nobody teaches the baby to suck, just as no one teaches a sea turtle hatchling to move toward the ocean. Learning, like reflexes and instincts, allows an organism to adapt to its environment. But unlike instincts and reflexes, learned behaviours involve change and experience: learning is a relatively permanent change in behaviour or knowledge that results from experience. In contrast to the innate behaviours discussed above, learning involves acquiring knowledge and skills through experience. Looking back at our surfing scenario, Julian will have to spend much more time training with his surfboard before he learns how to ride the waves like his father.
A relatively permanent change in behaviour or knowledge that results from experience.
Learning to surf, as well as any complex learning process (e.g., learning about the discipline of psychology), involves a complex interaction of conscious and unconscious processes. Learning has traditionally been studied in terms of its simplest components—the associations our minds automatically make between events. Our minds have a natural tendency to connect events that occur closely together or in sequence. associative learning occurs when an organism makes connections between stimuli or events that occur together in the environment. You will see that 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. These learning processes will be discussed in detail later in the chapter, but it is helpful to have a brief overview of each as you begin to explore how learning is understood from a psychological perspective.
In classical conditioning, also known as Pavlovian conditioning, organisms learn to associate events—or stimuli—that repeatedly happen together. We experience this process throughout our daily lives. For example, you might see a flash of lightning in the sky during a storm and then hear a loud boom of thunder. The sound of the thunder naturally makes you jump (loud noises have that effect by reflex). Because lightning reliably predicts the impending boom of thunder, you may associate the two and jump when you see lightning. Behavioural researchers study this associative process by focusing on what can be seen and measured: behaviours. Researchers ask if one stimulus triggers a reflex, can we train a different stimulus to trigger that same reflex?
In operant conditioning, organisms learn, again, to associate events—a behaviour and its consequence (reinforcement or punishment). A pleasant consequence encourages more of that behaviour in the future, whereas a punishment deters the behaviour. Imagine you are teaching your dog, Hodor, to sit. You tell Hodor to sit, and give him a treat when he does. After repeated experiences, Hodor begins to associate the act of sitting with receiving a treat. He learns that the consequence of sitting is that he gets a doggie biscuit ([link]). Conversely, if the dog is punished when exhibiting a behaviour, it becomes conditioned to avoid that behaviour (e.g., receiving a small shock when crossing the boundary of an invisible electric fence).
Observational learning extends the effective range of both classical and operant conditioning. In contrast to classical and operant conditioning, in which learning occurs only through direct experience, observational learning is the process of watching others and then imitating what they do. A lot of learning among humans and other animals comes from observational learning. To get an idea of the extra effective range that observational learning brings, consider Ben and his son Julian from the introduction. How might observation help Julian learn to surf, as opposed to learning by trial and error alone? By watching his father, he can imitate the moves that bring success and avoid the moves that lead to failure. Can you think of something you have learned how to do after watching someone else?
All of the approaches covered in this chapter are part of a particular tradition in psychology, called behaviourism, which we discuss in the next section. However, these approaches do not represent the entire study of learning. Separate traditions of learning have taken shape within different fields of psychology, such as memory and cognition, so you will find that other chapters will round out your understanding of the topic. Over time these traditions tend to converge. For example, in this chapter you will see how cognition has come to play a larger role in behaviourism, whose more extreme adherents once insisted that behaviours are triggered by the environment with no intervening thought.
- Non-associative learning involves only one stimulus; habituation and
sensitization are examples.
In the former, there is a decrease in the response to an innocous stimulus. In the later, the response tendency increases.
Cognition involves mental processes such as thinking, knowing, problem-solving, and remembering According to cognitive theorists, these processes are critically important in a more complete, more comprehensive view of learning.
Three main types:
Latent learning, and
Instincts and reflexes are innate behaviours—they occur naturally and do not involve learning. In contrast, learning is a change in behaviour or knowledge that results from experience. There are three main types of learning: classical conditioning, operant conditioning, and observational learning. Both classical and operant conditioning are forms of associative learning where associations are made between events that occur together. Observational learning is just as it sounds: learning by observing others.
Which of the following is an example of a reflex that occurs at some point in the development of a human being?
child riding a bike
infant sucking on a nipple

occurs by observing others
Two forms of associative learning are ________ and ________.
classical conditioning; operant conditioning
classical conditioning; Pavlovian conditioning
operant conditioning; observational learning
operant conditioning; learning conditioning
In ________ the stimulus or experience occurs before the behaviour and then gets paired with the behaviour.
Critical Thinking Questions
Compare and contrast classical and operant conditioning. How are they alike? How do they differ?
Both classical and operant conditioning involve learning by association. In classical conditioning, responses are involuntary and automatic; however, responses are voluntary and learned in operant conditioning. In classical conditioning, the event that drives the behaviour (the stimulus) comes before the behaviour; in operant conditioning, the event that drives the behaviour (the consequence) comes after the behaviour. Also, whereas classical conditioning involves an organism forming an association between an involuntary (reflexive) response and a stimulus, operant conditioning involves an organism forming an association between a voluntary behaviour and a consequence.
What is the difference between a reflex and a learned behaviour?
A reflex is a behaviour that humans are born knowing how to do, such as sucking or blushing; these behaviours happen automatically in response to stimuli in the environment. Learned behaviours are things that humans are not born knowing how to do, such as swimming and surfing. Learned behaviours are not automatic; they occur as a result of practice or repeated experience in a situation.
