A common System of Calssification
Species
A classification given to a group of living organisms who can exchange genes and reproduce.
instinct
Innate responses of a species
Natural Selection
Ensures that appropriate responses lead to survival and that the less successful responses lead to death. (Gezz)
Ethology
A science of Animal Behavior
Evolution
A natural process of change and development. Charles Darwin believed that it leads to a new species.
Charles Darwin (1809-1882)
A British Scientist from the 19th century.
Konrad Zacharias Lorenz
(1903-1989)
One of the founding fathers of modern ethology.
Imprinting
A process by which young animals acquire responses from a auditory and visual cue from the parents.
Tinbergen’s four Questions
Ethology / study of animal behavior
- Function; survival , & reproduction
- Mechanism ; stimuli cause and effect
- Development ; does behavior change w/ age? What causes the behavior?
- Evolutionary History ;
Behaviorism Timeline
First half of the twentieth century, behaviorism became the dominant school of animal psychology.
Behaviorism
The theory that behavior is learned, rather than genetically programmed
John B Watson
American Psychologist who originated Behaviorism
John B Watson’s
Stimulus Response Theroy
All complex forms of behavior, include emotions, thoughts, and habits are complex muscular and glandular responses that can be observed and measured.
Behaviorists Theorized
Animals are born a “blank slate” where behavior can develop through environment, learning, & conditioning.
Behaviorists recognize Conditioning ; 2 types
- Classical Conditioning
- Operant Conditioning
Classical Conditioning
Is the association of stimuli that happens at approximately the same time, or the same area
Operant Conditioning
Is the association of punishment or reward
BF Skinner (1904-1990)
American Psychologist
Devised experiments on caged rats conditioning using operant conditioning.
Instrumental Learning
Trial and error learning
Reinforcement
- Positive Reinforcement; Adding something to increase behavior . ( a treat for sitting on cue)
- You take something away to increase a behavior.
Punishment
- Positive Punishment occurs when you add something to decrease a behavior. ( using an air horn to stop a dog from barking)
- Negative punishment
Removing something to decrease behavior ( turning your back when a dog jumps on you)
Primary reinforcers
Stimuli that have a biological basis.
Secondary reinforcers
Completely neutral or weakly positive reinforcement. (Games, tug on rope)
Sociobiology
The study of biological basis of a social behavior. Extends the concept of Natural Selection to the social behavior of an animal.
Instincts
Inherited or genetic coded responses to environmental stimuli. Instincts enable members of a species to respond appropriately to a wide range of situations in the natural world.
Imprinting
A rapid learning process that enables the very young to recognize and bond with their caretaker
