  1. A sequence of unlearned acts that is unchangeable- one initiated it is usually carried to completion- triggered by an external sensory stimulus known as a sign stimulus
    ex. spiders because they make their webs look the same, circular
    Fixed action pattern (FAP)
  2. A powerful chemical attractant used to manipulate the behavior of others
  3. In animals, trigger that initiates a fixed action pattern of behavior
    Sign stimulus
  4. Behaviors that seem to be genetically programmed
    Innate behavior
  5. A simple change in activity or turning rate in response to a stimulus
    ex. Sowbugs
  6. The process by which new behavior is learned
    ex. learning to read and write
    Learned behavior
  7. An oriented movement toward (positive) or away (negative) from a stimulus
    ex. trout
  8. A loss of responsiveness to stimuli that convey little or no new information- one of the simplest forms of learning
    ex. the "cry-wolf" effect
  9. Critical period- a limited developmental time period when certain behaviors can be learned
    ex. geese and whooping cranes
  10. The ability to associate one environmental feature with another
    ex. Monarch butterfly and victory butterfly (look very similar, slightly different color but pretty much the same markings)
    Associative learning
  11. An arbitrary stimulus becomes associated with a particular outcome
    Classical conditioning
  12. An animal learns to associate one of its own behaviors with a reward or punishment
    ex. "Trial and error" learning
    Operant conditioning
  13. Behavior that appears to benefit others at a cost to oneself- selfishness
  14. Natural selection favors altruism when the benefits to the recipient multiplied by the coefficient of relatedness exceeds the cost to the altruist rB>C
    Hamilton's Rule
  15. The probability that two individuals will share a copy of a particular gene
    Coefficient of relatedness
