Understanding Learning 

As humans, we have the incredible ability to learn and adapt to our surroundings. Learning is a fundamental aspect of our lives, allowing us to develop new behaviors that help us navigate the changing world. For example, we learn to anticipate important events like receiving food or experiencing pain. Through learning, we also discover which actions lead to rewards and which result in negative outcomes. Moreover, we can acquire new behaviors by observing events and individuals, even those we have never directly encountered. In AP Psychology, we explore how learning shapes our behaviors and interactions with the environment. From understanding how children learn to examine the influence of culture and social roles on our behavior, this unit offers a comprehensive understanding of the complexities of human learning processes, including associative learning. 

Learning is a complex process that involves acquiring new knowledge or behaviors through experiences, interactions, and observations. In psychology, the behavioral perspective emphasizes the importance of conditioning in shaping our learning experiences. Behaviorists who follow this perspective concentrate on studying observable behaviors rather than focusing on internal mental processes. Some basic forms of learning include classical conditioning, where we associate two stimuli together to produce a learned response, and operant conditioning, where behaviors are reinforced or punished to increase or decrease the likelihood of them occurring again. These foundational principles provide insights into learning and adapting to our environment.

Classical ConditioningPhotograph of Ivan Pavlov

The first is Ivan Pavlov's classical conditioning theory. Pavlov accidentally discovered the principles of classical conditioning during his research on dogs' digestive systems. His research helped us understand how we learn to associate noteworthy events with automatic responses. B.F. Skinner later introduced the idea of operant conditioning, which switches the emphasis from reflex-based learning to learning shaped by consequences. Later, Albert Bandura illustrated the power of observational learning in his experiment with the Bobo doll, thus introducing the concept that behavior is learned through the environment.  

Ivan Pavlov devoted two decades to studying dogs' digestive systems. In his experiments, he presented the dog with food and measured saliva. Pavlov found that the dogs began salivating before the food presentation and decided to investigate further. His findings showed that the animals created an association between two stimuli, thus producing a reflective response. This accidental discovery was the beginning of classical conditioning.

Special Terms Created by Pavlov to describe Classical Conditioning:

Unconditioned Stimulus (UCS)

A stimulus that elicits a natural, reflexive response.

Unconditional Response (UCR)

The natural reflexive response to the UCS.

Neutral Stimulus

A stimulus that by itself elicits no response.

Conditioned Stimulus (CS)

The former neutral stimulus has now acquired the ability to elicit the reflexive response.

Conditioned Response (CR)

 The learned reflexive response to a conditioned stimulus.

Acquisition

 

The initial phase of learning when the neutral stimulus is paired with the UCS.

During acquisition the neutral stimulus is paired with the UCS over and over again. Timing is important during this phase. It is best to present the neutral stimulus right before the UCS.

 

 

 

View the stages of Pavlov's Classical Conditioning of dogs:

Summary of Pavlov's Method: 1. Prior to conditioning, the food is the UCS and the salivating is the UCR. 2. Prior to conditioning, the bell is the neutral stimulus. At this point it does not elicit the reflex. 3. During conditioning, the bell (neutral stimulus) is presented immediately before the food. The natural reflex is produced. 4. After conditioning, the bell is no longer neutral. It can now be called the CS because it elicits the conditioned reflex. The salivation response is now the CR.

Understanding the Significance of Pavlov's Work

Pavlov's work remains crucial in the field of psychology for various reasons. His research on classical conditioning laid the foundation for the behavioral perspective, which focuses on learning through conditioning. Behaviorists, inspired by Pavlov, emphasize observable behavior over mental processes. By demonstrating that psychological phenomena can be objectively studied, Pavlov highlighted the importance of empirical evidence in psychological research. Additionally, his findings on classical conditioning being a fundamental form of learning applicable to all species revolutionized our understanding of behavior and learning processes.
