  1. Know Tinbergen's study of digger wasp behavior.
    How he did it and what he found out.
    Pine cones placed around nest, then moved. Digger wasp maps arrangement of landmarks to locate nest.
  2. Define fixed action pattern and give an example.
    • An unchangeable sequence of actions (innate behavior).
    • Graylag goose sees an egg outside her nest. Fixed action pattern will begin as she leaves the nest-circles the egg back to the nest with her beak. If she sees the egg go outside the nest, then you take the egg away? She will still push the nonexistent egg.
  3. What amount of time is a circadian rhythm based on?
    Innate rhythms within 24 hours.
  4. Know the difference between independent and dependent variables in an experiment.
    • Independent = one that stands alone and isn't changed by the other variables you are trying to measure.
    • Dependent = one that depends on other factors, such as depending on what you do with the independent variable.
  5. What type of learning is portrayed when people near an airport get used to the sound of the airplanes and do not notice it anymore?
    Habituation through desensitization.
  6. Knot the definition of habituation.
    When an animal learns NOT to respond to a repeated stimulus that gives little or no information.
  7. What is imprinting?
    Know Lorenz' experiment.
    • Learning that is limited to a specific time period in an animal's life and is usually irreversible.
    • Lorenz divided goose eggs into two groups.  The eggs hatched to mom followed her. The ones hatched to Lorenz followed him.
  8. Know Pavlov's dog experiment. What did he do?
    What do we call this behavior?
    What is the definition?
    • Trained a dog to salivate to the sound of a bell ringing whenever he was fed.
    • Classical conditioning
    • Conditioning = learning in which a particular stimulus or response is linked to a reward or punishment.
  9. A rat that learns a maze by getting cheese as a reward at the end is learning by _____ _____.
    operant conditioning
  10. Be able to pick out the control (what doesn't change) in an experiment.
    Look over the Spongebob examples.
    The non-changing condition.
  11. Know the 3 main graphs and what each is used to show.
    • Pie/circle graphs = used to show parts of a whole
    • Bar graphs = used to compare amounts
    • Line graphs = used to show the change of one piece of information as it relates to another change
  12. Know how to do mean, median, and mode.
    • Mean = add the numbers, then divide by the number of values you added together.
    • Median = put the numbers in order from least to greatest. The middle number is the mean. (If even number set, then take the two middle numbers and find their mean.)
    • Mode = the number that occurs most often in a set of data.
