In-Depth Notes on Learning Processes

Learning Objectives

• Define learning: A relatively enduring change in behavior resulting from experience.

• Identify three types of learning processes.

  • Nonassociative learning

  • Associative learning

  • Social learning

• Describe nonassociative learning processes: Habituation and sensitization, and explain significance of each.

Types of Learning

• Nonassociative Learning:

  • Involves a change in behavioral response after repeated exposure to a single stimulus.

  • Example: Moving to a new house near train tracks; initially disturbed by noise but eventually habituated to it.

• Associative Learning:

  • Involves linking two stimuli or events that occur together.

  • Example: Dog running to door when it sees a leash, associating it with going for a walk.

• Social Learning:

  • Learning that occurs through social means—observing others or receiving verbal instructions.

  • Example: Learning about mask-wearing during COVID-19 through media and social observation.

Nonassociative Learning

• Habituation:

  • Decrease in behavioral response after repeated exposure to a stimulus.

  • Example: Ignoring city sirens after living near them for a while.

• Sensitization:

  • Increased behavioral response after exposure to a meaningful stimulus (often threatening).

  • Example: Heightened response to the smell of smoke while studying, focusing attention to potential dangers.

Classical Conditioning

• Classical Conditioning:

  • Involves learning that a stimulus predicts another stimulus (Pavlovian conditioning).

  • Key Terms:

  • Unconditioned Stimulus (US): Stimulus that elicits a response without prior learning.

  • Unconditioned Response (UR): The unlearned response to the US.

  • Conditioned Stimulus (CS): Initially neutral stimulus that comes to elicit a response after it is associated with the US.

  • Conditioned Response (CR): The learned response to the CS.

• Example of Classical Conditioning: Pavlov’s dogs salivating to the sound of a metronome after training.

Operant Conditioning

• Operant Conditioning:

  • Learning process in which the consequences of an action determine the likelihood of that action being performed in the future.

  • Law of Effect: Behaviors leading to satisfying outcomes become more likely to occur.

• Reinforcement: Increases behavior.

  • Positive Reinforcement: Adding a stimulus to increase the probability of a behavior (e.g., giving treats).

  • Negative Reinforcement: Removing an unpleasant stimulus to increase behavior (e.g., turning off an alarm by getting up).

• Punishment: Decreases behavior.

  • Positive Punishment: Adding an unpleasant stimulus to decrease behavior (e.g., scolding).

  • Negative Punishment: Taking away a desired stimulus to decrease behavior (e.g., losing privileges).

Schedules of Reinforcement

• Continuous Reinforcement: Behavior is reinforced every time it occurs.

• Partial Reinforcement: Behavior is reinforced intermittently.

  • Schedules include:

  • Fixed Interval (FI): Reinforcement after a set time period.

  • Variable Interval (VI): Reinforcement after varying time periods.

  • Fixed Ratio (FR): Reinforcement after a set number of responses.

  • Variable Ratio (VR): Reinforcement after an unpredictable number of responses.

Social Learning Theory

• Modeling: Imitating observed behavior, influenced by the model's attractiveness or status.

• Vicarious Learning: Learning consequences by watching others (e.g., seeing someone else get punished for misbehaving).

• Instructed Learning: Children learn through verbal instructions about behaviors and associations.

Phobias and Addictions

• Phobias: Fear responses that are disproportionately high relative to the actual threat, often learned through classical conditioning or social observation.

• Addiction: Involves operant conditioning where drug use is reinforced by positive effects and can be linked to environmental cues through classical conditioning, leading to cravings and habitual use.

Conclusion

Understanding learning processes enables adaptation to environments, drives behavior, and shapes responses to stimuli and social contexts. Different theories emphasize various components of learning, from behavioral outcomes to the role of observation and instruction in social settings.
