Chapter 12 - Skinner Flashcards
Respondent behaviour
Responses made to or elicited by specific environmental stimuli (I.e. knee jerk)
Reinforcement
The act of strengthening a response by adding a reward, thus increasing the likelihood that the response will be repeated
Extinction
The process of eliminating a behaviour by withholding reinforcement
Operant behaviour
Behaviour emitted spontaneously or voluntarily that operates on the environment to change it
Operant conditioning
The procedure by which a change in the consequences of a response will affect the rate at which the response occurs (behaviour under control of reinforcers)
Reinforcement schedules
Patterns or rates of providing or withholding reinforcers:
- fixed interval
- fixed ratio
- variable interval
- variable ratio
(I.e reinforcement doesn’t occur every time)
Conditioning
Substitution of one stimulus for another
Fixed interval (schedule of reinforcement)
Reinforcer following a fixed amount of time after response
Example: buy 9 cups of coffee and get the 10th for free
Fixed ratio (schedules of reinforcement)
Reinforcer following a fixed number of responses
Example: being paid every 2nd week, yet still go to work every day because you know the pay is coming - showing up allows you to be paid at the end of the pay period
Variable interval (schedules of reinforcement)
Reinforcer after unpredictable amount of time
Example: fishing - unpredictable time to catch a fish, if at all
Variable ratio (schedules of reinforcement)
Reinforcer after unpredictable number of responses (based on an average number of responses between reinforcers, but there is great variability around that average)
Example: gambling
Successive approximation
An explanation for the acquisition of complex behaviour. Behaviour such as learning to speak will be reinforced only as it comes to approximate or approach the final desired behaviour
Behaviour that is closer and closer to the desired behaviour is rewarded until only the desired behaviour will elicit a reward
Superstitious behaviour
Persistent behaviour that has a coincidental and not a functional relationship to the reinforcement received (but behaviour is continued even when reinforcement does not continue)
Self-control
The ability to exert control over the variables that determine our behaviour. Some control is exerted over external variables through self-control techniques such as:
- stimulus avoidance
- self-administered satiation
- aversive stimulation
- self-reinforcement
Stimulus avoidance
Removing oneself from an external variable
Example: alcoholic removing the liquor from their house
