  1. What is learning?
    a systematic, relatively permanent change in behavior that occurs through experience.
  2. What is classical conditioning?
    learning process in which a neutral stimulus becomes associated with a meaningful stimulus and accquires the capacity to elicit a similar response
  3. Who was Pavlov?
    Russian physiologist that studied how dogs digest food
  4. What are the NS,UCS,UCR,CS,and CR? be able to identify each in an example and in Pavlov's original studies.
    • UCS(unconditional stimulus) produces a response without prior learning.
    • NS(neutral stimulus) can detect but no reaction.
    • UCR(unconditional response) reaction that is unlearned.
    • CS(conditional stimulus)learned reaction detectwith 5 senses.
    • CR(conditional response) learned
  5. Pavlov experinment
    • UCS- meat powder
    • UCR- dog salivates
    • NS- sound of pavlov bell( prior to pairing with the meat powder)
    • CS-sound of pavlov bell
    • CR-dog salivates
  6. What are extinction and spontaneous recovery?
    extinction- the conditional response is weakened by the conditional stimlus and the unconditional stimulus.(pavlov rang bell but did not present food and the dog stop salivating)

    spontaneous recovery-conditional response recurs after a time delay and without additional learning(when pavlov rang the bell the next day, the dog salivated)
  7. Who was little Albert? Whose research is he associated with? What were the NS,UCS, etc in the famous study?
    • little Albert was the baby in Watson and Rayner study with the rats,
    • CS- the white rats
    • UCS- the bell
    • UCR- the noise that caused albert to cry
    • CR- albert began to fear the rat when the noise was not sounded
  8. What is aversive conditioning?
    a form of treatment that consists of repeated pairings of a stimulus with a very unpleasant stimulus
  9. What is operant conditioning?
    also called instrumental conditioning, a form of associative learning in which the consequence of a behavior change the probabiltiy of the behaviors occurence.
  10. What is a consequence? What type of conditioning involves the power of consequence?
    a type of action either a negative or positive response according to behavior, operant conditioning.
  11. Who was Thorndike? What appartus did he use? What law did he propose?
    an american psychologist, studying cats in a puzzle box, he proposed the law of effect( behaviors followed by positive outcomes are strengthned and that behaviors followed by negative outcomes are weakened)
  12. What kind of animal did the following work with: Pavlov, watson, skinner, thorndike, kohler, and tolman?
    • Pavlov- dogs
    • Watson- white rats
    • Skinner-pigeon
    • Thorndike-cats
    • Kohler-apes
    • Tolman-apes
  13. What is shaping?
    rewarding approximations of the desired behavior
  14. What is contionous versus partial reinforcement?
    contionous reinforcement is when a behavior is reinforced everytime it occurs, versus partial reinforcement when a reinforcer follows a behavior only a portion of the time.
  15. What are the different schedules of partial reinforcement?
    fixed ratio- reinforcement follows a set # of behaviors

    variable ratio- reinforcement follows an unpredicitable # of behaviors(slot machine)

    fixed interval- reinforcement follows behavior that occurs after a set amount of time has elapsed(paid every two weeks)

    variable interval-reinforcement follows behavior that occurs afetr an unpredictable amount of time has elapsed( fishing, class with pop quiz required points)
  16. What is reinforcement and punsihment?
    reinforcement is the process by which rewarding stimulus or event following a particular behavior increases the probabiltiy that the behavior will happen again.

    punishment is a consequence that decreases the likelyhood of a behavior happening again
  17. What is a primary versus secondary reinforcer.
    a primary reinforcer is innately satisfying that is a primary reinforcer does not take any learning on the organism part to make it pleasurable

    a secondary acquires its positive value through an organisms experience, a secondary reinforcer is a learned or conditioned reinforcer.
  18. What is positive versus negative reinforcement?
    positive reinforcement- behavior followed by a rwarding consequence( rewarding stimulus is added)you turn in your project on time and the manager praises you for turning it in on time

    negative reinforcement- behavior followed by a rewarding consequence aversive unpleasant behavior is removed( you take asprin for a headache and your headache goes away)
  19. What is postive versus negative punishment?
    positive punishment- behavior followed by aversive consequence unpleasant stimulus is added(you don't replace the tires on the family car when your parent asks you to, your parents get angry with you for not replacing the tires)

    negative punishment-behavior followed by aversive consequence rewarding stimulus is removed( your younger sister comes home two hours late and she gets grounded for two weeks)
  20. What is vicarious conditioning?
    vicarious reinforcement- a reward for an activity increases the chances that an observer will repeat the behavior

    vicarious punishment-seeing the model punished makes the observer less likely to repeat the behavior
  21. What is observational learning?
    learning that occurs when a person observes and imitates behavior(modeling) Albert Bandura- social cognitive theory BoBo Doll
  22. What is a BoBo Doll and why do we care about it in this class?
    a BoBo Doll is a clown that bobbles back and forth when hit and the BoBo Doll was used to represent observational learning when kids see someone doing something it influences their actions
  23. What is biological prepardness and instinctive drift?
    instinctive drift- the tendency of animals to revert to instinctive behavior that interfers with learning

    biological prepardness- the species specific biological predisposition to learn in certain ways but not others
  24. What is latent learning? Who described it first?
    also called implicit learning, unreinforced learnign that is not immediately reflected in behavior(Tolman and Honzik)
  25. What is developnmental psychology?
    the pattern of continuity and change that occurs throughout the lifespan
  26. What are the cross sectionals and longitudinal designs? What are the advantages and disadvantages of both?
    Cross sectional studies recruit people of different age groups and then compare them the disadvantage is cohort when you have people born around the same time

    Longitudinal studies recruit people and follow them over time disadvantage is attrition losing thing overtime
  27. What is the nature vrs nuture debate?
