Definition
Any relatively permanent change in behavior (or behavior portential) resulting from experience |
|
|
Term
|
Definition
A form of learning in which two stimulus events become associated in such a way that the occurance of one reliably predicts the occurance of another |
|
|
Term
|
Definition
- Discovered classical conditioning
- Dogs salivated from thing other than meat normally associated with recieving meat (i.e. the trainers or the sound of a bell)
|
|
|
Term
|
Definition
Evokes an unconditional (automatic) response the first time it's presented (i.e. meat) |
|
|
Term
|
Definition
Stimulus which does not evoke an automatic response (i.e. a bell) |
|
|
Term
|
Definition
Neutral stimulus repeatedly paired with unconditioned stimulus until it evokes a response |
|
|
Term
|
Definition
Repsonse to a conditioned stimulus (i.e. salivating at a bell) |
|
|
Term
|
Definition
- Proecess by which a neutral stimulus/conditioned stimulus (bell) gains the ability to elicit a condtioned response (salivation) through repeated pairings of an uncondtioned stimulus (meat) with neutral conditioned stimulus
- Proceeds rapidly at first,increasing as the number of pairings between conditioned stimulus and unconditioned stimulus increases
- There is a limit on this effect
|
|
|
Term
|
Definition
The conditioned stimulus gradually loses the ability to evoke a conditioned response when it is no longer follewed by an unconditioned stimulus |
|
|
Term
|
Definition
The pairing of an unconditioned stimulus with a neutral/condtioned stimulus once after the conditioned response had gone to extinction causes the reappearance of a weakened conditioned response |
|
|
Term
Classical Conditioning to Phobias |
|
Definition
- Little Albert was introduced to a netural stimulus, which was a white and fluffy rat.
- This stimulus was paired with a loud noise, which frightened Little Albert
- The pairing of the loud noise with the rat caused a conditioned response, which emerged in a fear response to rats
- This fear response became generalized to anything white and fluffy
- John Watson presiding psychologist on experiment
|
|
|
Term
|
Definition
Conditioned response to a stimulus similar to the conditioned stimulus |
|
|
Term
|
Definition
Only conditioned response to conditioned stimulus and not similar stimuli |
|
|
Term
Systematic desenstization |
|
Definition
A step-by-step process of desensitizing client to a feared object/experience |
|
|
Term
|
Definition
A person suffering from an anxiety disorder is taken directly into feared situation until anxiety subsides |
|
|
Term
|
Definition
Behavior is instrumental in bringing about rewarding consequences |
|
|
Term
|
Definition
- If a response is followed by a reqrds, then that response will be strenghtened
- Response with no reward/punishment is weakened
|

Edward Thorndike's Puzzle Boxes |
|
Definition
Cats learned relatively quickly to press buttons in a sequence to get food |
|
|
Term
|
Definition
The process in learning in which consequences of a response determine the probability that the response will be repeated |
|
|
Term
|
Definition
- Psychologist who worked with stimulus/event that increases the probability that the response it follows will be repeated
- The Skinner Box: Trained pidgeons to complete certain sequences of events (Pigeon torpedos, pingpong, etc.)
- Shaping: Reqrding successive approximations of a target behavior
|
|
|
Term
|
Definition
- Works to increase a behavior by adding a pleasant stimulus
- i.e. Gold stars
|
|
|
Term
|
Definition
- Works to increase a behavior by removing an unpleasant stimulus
- i.e. Allowing the class to go early for behaving well
|
|
|
Term
|
Definition
- Works to decrease a behavior by adding an unpleasant stimulus
- i.e. spanking, added chores
|
|
|
Term
|
Definition
- Works to decrease a behavior by removing a pleasant stimulus
- Removing freedom through grounding

Term
Fixed Interval reinforcement |
|
Definition
- Subject gets a reward based on the interval of time
- i.e. getting paid by the hour
|
|
|
Term
Variable Interval Reinforcement |
|
Definition
- The amount of time varies for the reward to be given
- i.e. Going fishing (variable time until a fish is caught)
|
|
|
Term
Fixed ratio reinforcement |
|
Definition
- A reward is given for the completion of a set number of behaviors
- i.e. Piecework--paid $10 for every five necklaces
|
|
|
Term
Variable Ratio Reinforcement |
|
Definition
- The number of behaviors rquired for the reward varies
- i.e. Slot machines--the number of pulls for a jackpot is random
- People will work the hardest for this kind of reinforcement
|
|
|
Term
|
Definition
- Also known as observational learning
- People learn through observing the behaviors of others
- Acquisition of and,later, action on new information, concepts or behaviors demonstrated by others
- Can be included with reinforcement (learning consequences)
|
|
|
Term
|
Definition
- Ran the Bobo Doll experiment--2 groups of kids showed video tapes of adults interacting with Bobo Doll
- 1st group shown a tape of violent behavior (i.e. punching, kicking) and perfomred similarly
- 2nd group shown nice behavior and treated the dolls nicely.
- When released into a room with many toys after a violent tape, some immediately went and hit on the Bobo doll like in the tape, others eventually went over, and the rest didn't go over but still exhibited attitudinal changes
- Results: Media affects some people in some manner some of the time; live models aren't needed
|
|
|
Term
|
Definition
People become more accepting of violence with increased exposure and don't resond as negatively as they should |
|

Term
Four Steps of Observational Learning |
|
Definition
- Attention: How much we consciously focus on other's behaviors
- Retention: Our ability to retain a representation of other's behavior in memory
- Production Process: Our ability to act on these memory representations
- Motivation: Theusefullness to us of the information acquired
|
|
|
Term
|
Definition
- The process of mentally working through a problem until the sudden realization of a solution occurs
- "Aha" phenomenon: sudden realization
- Wolfgang Kohler studied this aspect with apes as they used problem solving to receive fruit
|
|
|
Term
|
Definition
- Studied rats going through mazes
- Rats retained the information of the mazes (cognitive mapping) but showed no reason to exhibit their discoveriees until a reward was given
- When the reward was given, there was proof of latent learning
|
|
|
Term
|
Definition
The presentation of behavior from which an individual may learn |
|
|
Term
|
Definition
Studied learned helplessness, poverty, kidnapping, abuse in homes, etc. |
