Types of Learning - Animal Behaviour
Page 1: Introduction to Influences on Animal Behaviour
Lecture 2 focuses on innate and learned behaviours.
Page 2: Understanding Models
Model Definition: A simplified representation of a complex whole.
Used to understand and predict behaviours and processes.
Learning involves developing a personal working model of the world.
The term "model" comes from the Greek word meaning "misshapen ball of clay."
Page 3: Innate vs Learned Behaviours
Innate Behaviours: Previously termed "instinctive", now referred to as "unlearned" or "innate"; examples include suckling in newborns.
Learned Behaviours: Acquired through experience; examples include dietary choices based on past experiences.
Page 4: The Complexity of Behaviour Classification
The division into innate and learned behaviours is an oversimplification.
Imprinting: Young birds imprint on the first living object they encounter, typically a parent.
Birdsong: Innate preference for learning their species' song, but specific identity is learned.
Page 5: Personal Implications of Innate Behaviours
Questions arise about the potential discomfort from innate behaviours.
Encourages introspection on learned discomforts.
Page 6: Trypophobia Example
Introduction to the concept of “trypophobia,” an adverse reaction to certain images.
Page 7: Definition of Learning
Learning is converting flexible behaviours into more permanent actions.
It allows rapid implementation of behaviours based on experience—a crucial adaptation for survival.
Page 8: Utility of Learning
Prediction: Helps in associating causes and effects (e.g., rain clouds indicate rain).
Protection from Exploitation: Example of the Thynnine wasp and its interaction with the orchid.
Page 9: Advantages and Disadvantages of Innate and Learned Responses
Innate Responses:
Advantages: Quick, effective from a young age, essential for survival.
Disadvantages: Rigid, can be exploitable, less adaptive to complex environments.
Learned Responses:
Advantages: Adaptable to changing environments and complex interactions.
Disadvantages: Slower, requires prior knowledge or experience, demands higher cognitive resources.
Page 10: Tabula Rasa Concept
The "blank slate" idea suggests individuals are shaped primarily by experiences.
This is an oversimplification; animals possess innate structures shaping behaviour based on experiences.
Page 11: Shapes and Learning
Engages with concepts of perception and categorization using shapes named "Kiki" and "Bouba."
Page 12: Levels of Learning
Learning can occur at varying levels of complexity: habituation, associative learning, instrumental learning, and cognitive reasoning.

Habituation
Innate Behaviours
Page 14: Understanding Complexity in Learning
Sophistication does not imply superiority. Different learning mechanisms serve distinct purposes.
Page 15: Habituation Explained
Definition: A reduction in response to a benign stimulus after repeated exposure.
Examples include tube worms ceasing to respond and flavour aversion in humans.
Page 16: Everyday Examples of Habituation
Example: Desensitization to unpleasant smells, showcasing memory retention and recalibration of responses.
Page 17: Associative Learning
Known as Classical Conditioning (Pavlovian Conditioning).
Involves forming an association between a stimulus and an outcome: Pavlov's experiment with dogs.
Page 18: Classical Conditioning Components
Unconditioned Stimulus (US): Naturally elicits a response (e.g., meat).
Conditioned Stimulus (CS): Initially neutral, but becomes associated (e.g., bell).
Conditioned Response (CR): Learned reaction to the CS (e.g., salivating).
Reinforcers: Positive or negative incentives that affect future responses.
Page 19: Factors Affecting Learning Speed
Influenced by multiple factors:
Intensity of the US
Novelty of the situation
Speed of reinforcement following the CS
Intensity of the CS
Page 20: Instrumental Learning
Learning based on the association between an action and its consequences (rewards).
Differentiated from classical conditioning as it focuses on voluntary behaviours.
Page 21: Edward Thorndike’s Experiment
Demonstrated trial and error learning via cats escaping a box, illustrating instrumental learning concepts.
Page 22: Skinner's Operant Conditioning
Emphasized shaping existing behaviours rather than creating new ones in animal training contexts.
Page 23: Behaviour Relocation in Pigeons
Pigeons adapt their approach based on the type of reward (drinking vs. pecking), demonstrating flexibility in learnt behaviours.
Page 24: Bee Cognition Experiment
Bumblebee learning and social learning through observation; ability to innovate in complex behaviours.
Page 25: Facilitating Learning Associations
Focuses on simplicity versus complexity in associative learning based on natural pairings, as shown in Garcia's study.
Page 26: Image Recognition Exercise
Engages students to identify commonalities across different visuals.
Page 27: Follow-up Exercise
Further categorization tests to assess recognition and response patterns among students.
Page 28: Image Relation Task
Encourages participants to connect visuals identifying similarity.
Page 29: Categorization Difficulty
Highlights variability in learningabilities across species (e.g., pigeons vs. primates).
Page 30: Cognitive Reasoning Exposition
Insight learning defined; mechanisms for understanding complex problems recognized across species.
Page 31: Importance in Experimental Design
The example of Clever Hans showcases the need for stringent controls in behavioural experiments.
Page 32: Language Learning Queries
Questions regarding animal communication and understanding language nuances.
