  2. What is a fixed-action pattern?
    • innate behavioral response to specific patterns of stimulation (releaser) in the environment.
    • An example is the swimming action of fish
  3. Can circadian rythyms be modified by external factors?
    • Yes, sleep patterns can be changed by dark and light
    • Internal control of salivating while eating compared to external of being hungry when a clock rings
  4. The capacity for learning adaptive responses is closely correlated with what?
    degree of neurologic development
  5. What is habituation?
    decreased responsiveness to a repeated stimulation
  6. What is another name for classical conditioning and what is it?
    • Pavlovian conditioning
    • a conditioned reflex where a nuetral stimulus eventually elicits a conditioned response
  7. What is psuedoconditioning?
    When someone thinks they're using a nuetral stimulus and it's really not
  8. What is operant or instrumental conditioning?
    conditioning responses to stimuli with the use of reward or reinforcement
  9. Who is B.F. Skinner?

  10. How does negative reinforcement compare to punishment?
    • Negative reinforcement: When an action results in lack of a reward
    • Punishment: When action results in punishment
  11. What is habit family hierarchy?
    When there are many different results to a certain stimulus, an order is created on how we result to that stimulus based on past experience.
  12. How does stimulus generalization compare to stimulus discrimination?
    • Stimulus generalization: response to similiar, but not identical stimulus
    • Stimulus discrimination: response to identical or extremely close stimulus
  13. What is imprinting?
    When a behavior is "stamped in" during a critical period, usually right after birth (Konrad Lorenz)
  14. What are the different types of behavioral displays?
    Reproductive, agonistic, antagonistic
  15. What is the difference between pecking order and territoriality?
    • Pecking order: a dominant memeber of the species will prevail over a subordinate one.
    • Territoriality: distribution and defense of a piece of land
  16. What are the two types of pheromones and their purpose?
    • Releaser: reversible behavioral change (mating, alarm, toxic defense)
    • Primer: long term behavioral changes (estrous cycle in females)
