Animal Behavior Mrs. Rightler
Methods of Study Comparative psychology Ethology Behavioral ecology Sociobiology
Instinct Basic set of behaviors present at birth May need a trigger Behavior improves or changes with experience
Maturation Behavior seen after a period of development has occurred Improvement or change not based on experience but on time Ex. Tadpole swimming techniques
Imprinting Konrad Lorenz Critical time period ONLY Young animal develops attachment to another animal or object Rapid learning
Habituation Animal trained to ignore stimuli Dog examples
Classical Conditioning Pavlov’s dog Animal learns to respond to particular stimuli Basic obedience training
Instrumental Conditioning Trial-and-error learning Skinner Box Behavior can be “shaped”
Latent Learning Exploratory learning No obvious reward Helps animal learn about its surroundings
Insight Learning Animal uses experiences and thinking to solve problems. Tool use Primates
Behavior is Controlled by: Nervous system Endocrine system – Organizational effects – Activational effects
Animal Communication Transfer of information from one animal to the other (both must be mutually adapted) Visual Auditory Tacticle Chemical
Habitat Selection Two factors influence habitat choice – Physiological – Psychological
Foraging Behavior Process of locating food resources Cost vs. benefit analysis – Handling time – Nutritional value – Status value – Concentration/density
Specialists vs. Generalist
Social Behavior Members of the same species Usually live full-time in groups Can refer to predator-prey interactions
Group Living Animal society – stable group of individuals of the same species that have cooperative relationships outside of mating and raising young. Invertebrates and vertebrates
Advantages to Group Life Protection from predators Increase feeding efficiency Protection from elements Easy access to potential mates
Disadvantages of Group Life Competition for resources Diseases Parasites
Aggression Agonistic behavior Attacks Threat displays Maintains territory Maintains dominance hierarchy
Altruism Individual sacrifices reproductive potential for the benefit of others in the group – Honeybees – Turkeys – Naked mole rats Kin selection
Chapter 31 Animal Behavior
Behavioral Ecology Behavior-what an animal does and how it does it
Social Behavior Members of the same species Usually live full-time in groups Can refer to predator-prey interactions.

Animal Interactions Responses to the biotic environment.
Behavioral Ecology Chapter 37. Nature vs. Nurture Behavior To what degree do our genes (nature) and environmental influences (nurture) affect behavior?
Animal Behavior Chapter 34 /. What is a behavior? Any response to a stimulus (an external signal) Examples of stimuli Sounds Smells Sights (light vs dark)
Animal Behavior Ethology.
Animal Behavior Behavior What an animal does and how it does it Influenced by genes and environment (“nature and nurture”) Proximate and ultimate.
UNIT 10 Animal Behavior. Introduction Humans have always studied animal behavior Knowledge of animal behavior = human survival For example, understanding.
