Document Summary
Stimulus: response to changes in the environment. Elucidation of fixed action pattern innate, highly stereotypical behavior. Sign stimuli: exchanged between members of the same species. Sophisticated process; responses of organisms are modified as a result of experience. Capacity to learn is tied to length of life and complexity of the brain. Habituation: simplest form of learning; animal comes to ignore a persistent stimulus so it can go about its business. Associative learning: one stimulus becomes linked to another through experience; classical conditioning and operant conditioning. Classical conditioning: ivan pavlov; associative learning dogs associate sound of bell with food. Operant conditioning: trial and error learning ; animal learns to associate one of its own behaviors with a reward or punishment (repeats or avoids behavior) Imprinting: occurs during sensitive or critical period in early life of an individual and is irreversible. Any kind of interaction between two or more animals.
