Unit 3 - Behaviorism Flashcards
Stimulus
Event that produces a response
Learning/Conditioning
Change in behavior as a result of experience
Sā>R
Stimulus yields response
Response
Reaction to stimulus
Operant Conditioning
Procedure developed by B. F. Skinner to change behavior based on a reinforcement principle that follows a response
Positive reinforcement
Increases the likelihood that a response will continue
Negative reinforcement
Decreases the likelihood that a response will continue
Skinner box
Apparatus used to develop the theory of operant conditioning
Shaping
Method of approximations in which responses become more and more similar to the desired final response
Extinction
A procedure or process in which an established behavior is undone
Two types of reinforcement schedules
- Continuous reinforcement schedule
2. Partial reinforcement schedule
Continuous reinforcement schedule
Reinforcement is given every time the response is made
Partial reinforcement schedule
Reinforcement is only given some of the time
4 types of partial reinforcements
- Variable-Interval
- Fixed-Interval
- Variable-Ratio
- Fixed-Ratio
Variable-Interval reinforcement schedule
Reinforcement occurs after a varying amount of time
Ex: drug dogs on campus, pop quiz, CHP speed traps
Fixed-Interval reinforcement schedule
Reinforcement occurs after a fixed amount of time
Ex: break/lunch, vacations, hourly pay, quiz every Friday
Variable-Ratio reinforcement schedule
Reinforcement occurs after a variable amount of responses have occurred
Ex: slot machine, lottery ticket, random assignment going in grade book
Fixed-Ratio reinforcement schedule
Reinforcement occurs after a fixed amount of responses have occurred
Ex: buying bonus (BOGO), driving lessons (3=license), 2 violations=Saturday school
Classical conditioning
A type of simple learning based on repeated association where two stimuli are linked together and either stimuli can yield the response. Developed by Ivan Pavlov by observing dogs
4 types of stimuli and responses
- Unconditioned stimulus
- Conditioned stimulus
- Unconditioned response
- Conditioned response
Unconditioned stimulus
A stimulus that elicits a response without conditioning
Ex: smell one of your favorite foods and you become hungry
Conditioned stimulus
A previously neutral stimulus that elicits a response as a result of an experience
Ex: here fire alarm and go to field
Conditioned response
The response that occurs as a result of conditioning
Ex: waking up exactly at 7 am in the morning
Unconditioned response
An automatic, unlearned response. A reflex (instinct)
Ex: slamming on the brakes in a car when someone pulls out in front of you
