Introduction to Learning and Behavior: Historical Perspectives and Behavioral Schools

Introduction to Learning and Behavior

  • Course Source: These notes are based on Chapter 1 of the textbook Introduction to Learning and Behavior (4th Edition) by Powell et al., as presented by Dr. Ramos Nunez.

  • Overarching Goal: The study of learning and behavior is designed to answer fundamental research questions including:

    • Why do I behave the way I do?

    • Why do others behave the way they do?

    • What causes our behavior?

  • General Scope: While psychology is broadly defined as the study of behavior and mental processes, this specific course focuses almost exclusively on behavior rather than internal mental processes or the "mind."

Defining Key Concepts in Learning and Behavior

  • Learning: The course explores various facets of definition, including how psychologists define learning specifically versus general understanding.

  • Behavior Categories:

    • Overt Behavior: Behavior that can be directly observed by others.

    • Covert Behavior: Behavior that cannot be observed from the outside (internal processes).

  • Temporal and Qualitative Nature of Learning:

    • The change in behavior is considered "relatively permanent" rather than temporary.

    • Learning may not always manifest in immediate behavioral changes.

    • There is a distinct difference between Learning and Performance.

  • Innate vs. Acquired: The course questions whether all behaviors are learned and emphasizes the necessity of practice or experience in the learning process.

The Processes of Learning: Conditioning

  • Conditioning Defined: These are the actual procedures that modify behavior.

  • Two Fundamental Processes of Learning:

1. Classical Conditioning
  • Definition: The process of learning to make an involuntary or reflex response to a stimulus that was previously neutral.

  • Key Distinction: The behavior involved is involuntary (things we cannot control).

  • Notation Symbols:

    • Colon (::): Indicates that one event is followed by another (e.g., X:YX : Y means XX is followed by YY).

    • Arrow (\rightarrow): Indicates that an event produces a specific result (e.g., YZY \rightarrow Z means YY produces ZZ).

    • Study Example: Ivan Pavlov’s dog study.

      • Representation: Bell:FoodSalivation\text{Bell} : \text{Food} \rightarrow \text{Salivation}

      • This means the bell is followed by food, which leads to the response of salivation.

    • Target Behavior: In notation, the target behavior is identified by being underlined or italicized.

      • Example: BellSalivation\text{Bell} \rightarrow \underline{\text{Salivation}}

2. Operant Conditioning (Instrumental Conditioning)
  • Definition: The strengthening or weakening of a voluntary, goal-directed behavior as a result of its consequences.

  • Key Distinction: The behavior is voluntary and emitted by the organism rather than being a reflex.

  • Functional Example (Rat in a Box):

    • Behavior: Lever pressFood pellet\underline{\text{Lever press}} \rightarrow \text{Food pellet}

    • Future Effect: The likelihood of the lever press increases.

  • Mechanism: The behavior is emitted, a consequence follows, and this sequence makes it more likely the behavior will be repeated in the future.

  • Instrumental Nature: It is called "instrumental" because the behavior serves as a tool for the animal to get something it wants.

  • Real-World Example: Using an ATM.

    • Behavior: Inserting a debit card into the ATM.

    • Consequence: Receiving cash.

    • Future Effect: When cash is needed again, the behavior of using the ATM is repeated.

Philosophical and Historical Roots of Learning

The Nature vs. Nurture Debate
  • Plato (Nativism/Nature):

    • Everything humans know is inborn.

    • Knowledge is gained by reflecting on the contents of one's own mind.

    • This methodology refers to Introspection.

  • Aristotle (Empiricism/Nurture):

    • Everything we know is acquired through experience.

Aristotle’s Four Laws of Association
  1. Law of Similarity: Events that are similar to each other are readily associated.

  2. Law of Contrast: Events that are opposite of each other are readily associated.

  3. Law of Contiguity: Events occurring in close proximity to each other (in terms of time and space) are associated.

  4. Law of Frequency: The more frequently two items occur together, the more strongly they are associated.

Modern Roots and Dualism
  • René Descartes’ Dualistic Approach:

    • Proposed that humans have a dual nature.

    • The Mind has free will and controls voluntary behaviors.

    • The Body is mechanistic; behaviors are results of reflexes due to external stimulation.

    • The mind and body are viewed as separate entities.

  • British Empiricists:

    • Contradicted nativism; argued all knowledge is a function of experience (nurture).

    • John Locke: Proposed the concept of Tabula Rasa ("blank slate"), suggesting the mind is a blank slate that absorbs experiences from the world.

    • Other key figures: Thomas Hobbes, George Berkeley, David Hume, Immanuel Kant, and John Stuart Mill.

Early Schools of Thought in Psychology

Structuralism
  • Wilhelm Wundt: Known as the "Father of Psychology." He proposed using the scientific method to study human consciousness.

  • Edward Titchener: Brought structuralism to America.

  • Core Belief: It is possible to determine the structure of the mind by identifying basic elements through Introspection (self-reflection on thoughts and memory).

Functionalism
  • William James: The American psychologist who founded functionalism.

  • Core Belief: Consciousness functions as a unity. Study should focus on how the mind allows an organism to adjust to its environment.

  • Darwinian Influence: Heavily influenced by Charles Darwin’s Theory of Evolution.

    • Traits vary within species.

    • Many traits are heritable (passed from parents).

    • Organisms compete for limited resources, leading to the "survival of the fittest."

    • Those who survive reproduce and pass on adaptable traits (including behaviors and the ability to learn) to future generations.

Behaviorism
  • John B. Watson: Founder of behaviorism.

  • Core Belief: Consciousness cannot be reliably or scientifically studied because it is not visible.

  • Focus: Emphasis on environmental influences and observable (overt) behaviors.

  • Methodological Behaviorism: The specific branch focused on what can be measured and seen with the eyes.

The Five Schools of Behaviorism

1. Watson’s Methodological Behaviorism
  • Type: Stimulus-Response (SRS \rightarrow R) theory.

  • Learning: Involves a connection between a specific stimulus (SS) and a specific response (RR).

  • Stance: Became extremely "nurture" focused (empiricist).

  • Internal Events: Overlooks internal events (thoughts/feelings) because they cannot be observed or measured.

2. Hull’s Neo-Behaviorism
  • Definition: "New" behaviorism.

  • Internal Events: Suggested psychologists can make inferences about unobservable events if they are operationalized (defined in measurable terms).

  • Intervening Variables: Included internal physiological processes that mediate the environment and behavior.

  • Formula: Environmental Events (SS) \rightarrow Intervening Variables (Internal physiological processes like hunger, thirst, fatigue) \rightarrow Observable Behavior (RR).

3. Tolman’s Cognitive Behaviorism
  • Approach: Behavior is more than just an S-R chain; it is an overall pattern directed toward outcomes.

  • Cognitive Intervening Variables: Utilizes mental representations to explain behavior.

  • Cognitive Maps: A mental representation of spatial surroundings.

    • Example: Knowing the way from the Mariners Galley to the library at the College of Coastal Georgia because of an internal spatial map.

  • Intervening Variables: Expectations, hypotheses, and beliefs.

  • Formula: Environmental Events \rightarrow Internal Cognitive Processes \rightarrow Observable Behavior.

4. Bandura’s Social Learning Theory
  • Focus: Emphasizes observational learning.

  • Reciprocal Determinism: The idea that three factors influence each other:

    1. Internal Events (Person variables: thoughts and feelings).

    2. Environmental Events.

    3. Observable Behavior.

5. Skinner’s Radical Behaviorism
  • Core Stance: Rejects the use of internal events to explain behavior.

  • Covert Behaviors: Views thoughts and feelings as "covert behaviors" that themselves need to be explained, rather than using them as the explanation for other behaviors.

  • Influence: Stresses environmental consequences (past history) and acknowledges a role for genes.

  • Formula: Environmental Events \leftrightarrow Observable Behaviors \leftrightarrow Private Behaviors (Internal events).

Detailed Case Study: Tolman’s Latent Learning Study

  • Concept of Latent Learning: The idea that organisms may be learning even if they do not immediately show it, due to a lack of motivation. When motivation (a reward) is introduced, the learning becomes apparent.

  • Study Setup (Rats in a Maze):

    • Group 1 (Red Line\text{Red Line}): Rewarded with food every time they reached the end of the maze throughout the 16-day period.

    • Group 3 (Highest Error Group\text{Highest Error Group}): Never received a reward.

    • Group 2 (Green Line\text{Green Line}): No reward for the first 10 days; reward introduced on Day 11.

  • Variables:

    • Dependent Variable (yy-axis): Number of errors made in the maze.

    • Independent Variable (xx-axis): Time (16 days) and the reward condition (the three groups).

  • Results:

    • Group 1 showed a steady decrease in errors (learning).

    • Group 3 showed some decrease but maintained the highest error rate.

    • The Latent Learning Effect: Group 2 performed like Group 3 for the first 10 days. However, as soon as they received a reward on Day 11, their errors dropped drastically—even below the error rate of Group 1.

  • Conclusion: The rats in Group 2 were learning the maze the entire time (latently), but only demonstrated that learning once they had a reason (motivation/food) to do so.

  • Personal Application by Dr. Ramos Nunez: During community college, a lack of clear goals or documents for transfer led to poor performance. Once the situation changed and the goal of transferring to San Diego State University became achievable (motivation), grades improved dramatically, suggesting the "student skills" had been learned latently but weren't fully expressed until motivated.
