Animal Behavior Theories

Clever Hans and Lloyd Morgan's Canon

• The case of Clever Hans, a horse, demonstrated a flawed approach to studying animal behavior by attributing human-like problem-solving ability to a horse responding to cues.
• Lloyd Morgan's Canon emphasizes using the simplest explanation for animal behavior, avoiding complex interpretations unless supported by strong evidence.
• Scientists should avoid attributing human-like reasoning or emotions to animals without concrete evidence.
• Morgan's Canon suggests that simplicity is preferable to complicated explanations in interpreting animal behavior.

Tinbergen's Four Questions

• Niko Tinbergen's four questions (causation, mechanism, development, and function) provide a framework for understanding animal behavior.
• Causation (Mechanism): What are the internal stimuli and physiological mechanisms that trigger a given behavior?
• Development (Ontogeny): How does a behavior develop across an animal's lifespan?
• Function (Adaptation): How does a behavior contribute to survival and reproduction?
• Evolution (Phylogeny): How did behavior evolve in the species?

Fathers of Ethology

• Niko Tinbergen, Konrad Lorenz, and Karl von Frisch were pioneers in the study of animal behavior, sharing a Nobel Prize.
• Tinbergen introduced the concept of Fixed Action Patterns (FAPs) and developed the four questions approach, offering a way of analyzing animal behaviors and their evolutionary origins and purposes.
• Lorenz is known for his work on filial imprinting, exploring the formation of attachments in young animals.
• Von Frisch's work focused on animal communication, particularly with honeybees.

Fixed Action Patterns

• Fixed Action Patterns (FAPs) are instinctive, stereotypic behaviors triggered by specific stimuli.
• They are predictable and follow a specific sequence.
• They are innate and occur without learning.
• They complete themselves.
• They are triggered by a specific sign stimulus or releaser

Comparative Method

• The comparative method examines behavior across species to understand evolutionary origins and functions.
• Comparing species reveals evolutionary links and similarities and highlights the diverse cognitive strategies animals use.

Umwelt

• Umwelt, coined by Jakob von Uexküll, describes how an organism's sensory world is shaped by its environment.
• The umwelt is species-specific and highlights how organisms perceive their interactions with their environment based on needs and survival.

Animal Perception Experiments

• Animal perception is studied using controlled experiments involving tasks like shape discrimination, color recognition, and reactions to visual illusions.
• These experiments evaluate how animals process information based on their sensory capabilities.
• Studies use specific tasks and stimuli to test how animals approach and solve problems in relation to their sensitivities and abilities.

Imprinting

• Imprinting is a rapid learning process where animals form attachments to specific objects or individuals shortly after birth.
• This process happens during a critical period.
• Primary imprinting forms attachments with parents/carriers, facilitating care and survival.
• Secondary imprinting later may occur with a different object.
• Different types of objects lead to different degrees of success.

Ebbinghaus Illusion

• The Ebbinghaus illusion shows how surrounding shapes influence our perception of a central target shape.
• Studies on infants and animals suggest that cultural and biological factors influence how we perceive the illusion.
• A mix of evolutionary, cultural, and biological elements shape the way in which different species view or experience the world around them.
