Animal Behavior Behavior: Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles The way an organism reacts to internal or external changes Stimulus vs. Response Note Outline: Stimulus -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Any signal that carries information Response A single specific reaction to a stimulus Occurs because of several systems working together Sense systems Nervous system Muscles hormones Behavioral Ecology Ethology: the study of animal behavior Why study animal behavior? New conclusions about animal communication, animal emotions, and learning Animal training Understanding the world around us Innate vs. Learned Behaviors Note Outline: Innate: born into the animal (inherited) -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Does not have to learn this Includes reflexes and instincts Learned: developed during an animal’s life Modified by life experiences Innate vs. Learned Behaviors Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Types of Animal Behavior –Individual Animals 1. Instinct Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Natural or innate impulse Inclination of a living organism toward a particular behavior 2. Habituation Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Loss of response to stimulus Stimulus occurs so often that the animal learns to ignore it The “cry wolf” effect Ex. animal reacting to loud noise 3. Imprinting Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Learning at a particular age that is rapid Ex. a young animal acquires several of its behavioral characteristics from its parent Konrad Lorenz Migration 3. Imprinting – Operation Migration Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles 4. Classical Conditioning: Note Outline: -Behavior -Stimulus vs. Response Animals learn to make a mental connection between an arbitrary stimulus and reward Response becomes “conditioned” Ivan Pavlov’s Dogs -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles http://vimeo.com/5371237 5. Operant Conditioning Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles A method of learning that occurs through rewards & punishments Trial and error learning Focus on the consequences Ex. Skinner Types of Animal Behavior –Social Behaviors Between Animals 1. Competition for Resources Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Threatening and submissive acts 2. Dominance Hierarchy Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Social ranking within a group 3. Territoriality Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Territories are used for mating, feeding, and raising young 4. Altruistic Behavior Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Reduces individual fitness but increases the fitness of the group Courtship: a way to attract a mate Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Pheromones: a chemical/ smell secreted to attract a mate. Types of Animal Behavior – Behavioral Cycles 1. Migration Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Moving to a more suitable location Orientation: animal detects compass directions and travels in a straight path Navigation: animal determines relative position and detects compass directions 2. Hibernation Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Store up food and then sleep for the winter when little food is available Save energy 3. Estivation Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Sleep through the warmest part of the summer To save energy 4. Circadian Rhythms Note Outline: -Behavior -Stimulus vs. Response -Innate vs. Learned -Individual Animals -Social Behaviors -Behavioral Cycles Daily patterns of behavior; sleeping and eating
