Chapter 6- Operant Punishment Flashcards
What percentage of Americans approve of the use of physical or corporal punishment in schools?
50%
The procedure of providing consequences for a behaviour that reduces the strength of that behaviour
Punishment
What are the three characteristic features of punishment?
A behaviour must have a consequence, the behaviour must decrease in strength, the reduction in strength must be the result of the consequence
Any consequence of a behaviour that decreases the strength of that behaviour
Punisher
What are the two types of punishment?
Positive punishment and negative punishment
A punishment procedure in which a behaviour is followed by the presentation of, or an increase in the intensity of, a stimulus
Positive punishment
A punishment procedure in which a behaviour is followed by the removal of, or a decrease in the intensity of, a stimulus
Negative punishment
Describe how punishment differs from negative reinforcement
Positive punishment and negative reinforcement are often confused partly because both involve aversive events.
To punish is to weaken behavior, so any punishment procedure, positive or negative, makes behaviour less likely to occur. Thus, positive punishment means weakening behaviour by adding an aversive
Both use aversives, but one adds them and the other takes them away. The key is to remember that positive means add, and negative means subtract
Describe how the contingency variable influences the effectiveness of punishment
The degree to which the procedure weakens a behavior, or reduces its frequency, varies with the degree to which a punishing event is correlated with that behaviour
The greater the degree of contingency between a behaviour and a punishing event, the faster behaviour changes
Example: A person who is left every time they smile but not when they are not smiling makes it clear that that behaviour is contingent on slapping
Describe how the contiguity variable influences the effectiveness of punishment
The interval between a behaviour and a punishing consequence has a powerful effect on the rate of operant learning. The longer the delay the less effective is the procedure
Slapping a person for smiling immediately after doing so will result in more effectiveness and slapping them five seconds after they smile
Describe how Abramowitz and O’Leary demonstrated the relative effectiveness of immediate punishment in examining off-task behaviour
Teachers reprimanded first and second graders either immediately or two minutes after the off task behaviour had begun. Reprimands were effective in suppressing forms of off task behaviour in which the child interacted with another student, but only the immediate reprimands got results; delayed reprimands were useless
May be because during the delay interval, other behaviours are bound to occur, and these behaviours may be suppressed rather than the intended behaviour
Describe how the intensity of punishment influences it’s effectiveness
Very mild punishers have little effect. The greater the intensity of the punishing stimulus, the greater is the reduction of the punished responses
Example: a mild electric shock will probably not reduce behavior, but a painful shock will
Both Thorndike and skinner performed experiments that showed that punishment was in effective in reducing the strength of responding. What was wrong with these experiments?
The punishers they used were very weak, and studies with stronger punishers got much better results
Explain why the initial selection of punishment intensity is important in making punishment effective. Describe the implications this has for parents, teachers, and judges
Using an effective level of punishment from the very beginning is extremely important because beginning with a weak punisher and gradually increasing its intensity will tend to allow the punished behaviour to persist during these increases and in the end, a far greater level of punisher may be required to suppress the behaviour
By slowly increasing the level of punishment, it is as if we were trying to increase the persons tolerance for successively higher levels of punishment. If punishment is to be used, one must begin with a punisher that is intense enough to suppress the behaviour dramatically
Describe how the effectiveness of punishment is influenced by the reinforcers available for the punished behavior. Describe how inappropriate behaviour in a psychiatric hospital was differentially reinforced
The behaviours concerned and punishment are usually being maintained by reinforcement, therefore, the effectiveness of a punishment procedure depends on the frequency, amount, and quality of reinforcement the behaviour produces. If behaviour produces reinforcement, it may persist despite aversive consequences
Example: a child who throws tantrums is probably being reinforced by the attention they get from their parents
Inappropriate behaviour in a psychiatric hospital was differentially reinforced because it was the only way a patient could get the staff to interact with them at all. by creating a disturbance through shouting, fighting, and throwing things, which usually resulted in harsh treatment produced reinforcers such as attention
Describe how the availability of sources of reinforcement for alternative behaviours influences the effectiveness of punishment
Example: if pressing a lever is a rats only means of obtaining food, it is likely to continue pressing despite the shocks. On the other hand, if the rat has another way of obtaining food, the shocks will likely suppress lever pressing
When punishing and unwanted behavior, be sure to provide an alternative means of obtaining the reinforcers that maintained the undesirable behaviour
Example: if a child receives adult attention by playing with his food at the dinner table, make sure that he can obtain attention in more acceptable ways
Explain how the level of deprivation influences the effectiveness of punishment
Example: a rat that receives both shocks and food when I press is a lever made press the lever steadily if it is very hungry; however, the rat me not press the lever at all if it has recently eaten
In general, the greater the level of reinforcer deprivation, the more effective a punisher is
What is the disruption theory of punishment? Describe the evidence that supports/refutes this theory
Proposes that response suppression was due to the disruptive effect of aversive stimuli. Pointed out that when a rat is shocked it may jump, then freeze or run hurriedly about, behaviour that is clearly incompatible with, say, pressing a lever, so the rate of lever pressing is bound to decline
Research has undermined this explanation by producing Tukey findings: first, the effects of punishment are not as transient as Skinner thought it sufficiently strong of her symptoms are used
Secondly, punishment has a greater suppressive effect on behaviour than does aversive stimulation that is independent of behaviour
The disruption theory of punishment could not explain the discrepancy between contingent and non-contingent aversives
Describe the two-process theory of punishment
Says that punishment involves both Pavlovian and operant procedures.
Example: if a rat press is a lever and receives a shock, the lever is paired with the shock. Through Pavlovian conditioning, the lever then becomes a CS for the same behaviour aroused by the shop, including fear. The rat me escape the lever by moving away from it. Moving away from the lever is reinforced by a reduction of fear, and moving away from the lever necessarily reduces the rate of lever pressing
Flaws: the theory predicts that punishment would reduce responding in proportion to its proximity to the punished behaviour but this may not be the case. Birds who had learned to peck a sequence of discs who were then shocked did not peck the disk that was further removed from punishment, but behaviour rates on the two keys declined together
Describe the one-process theory of punishment. Who originally advocated this idea?
One process, operant learning, is involved in punishment. Punishment weakens behaviour in the same manner that reinforcement strengthens it
Thorndike originally advocated this idea
The pre-Mac principle supports this theory, low probability behaviour tends to punish high probability behaviour
Why is punishment used so frequently? Explain in terms of the effects of punishment, including the beneficial side effects
Punishment is used so frequently because it is effective, at least in the short term. Using punishment is reinforcing both positively and negatively.
Punishment is a very powerful procedure, it typically produces a very rapid and substantial reduction in the punished behaviour
Punishment is fast
Punishment has beneficial side effects such as when autistic children become more sociable, cooperative, affectionate, and make more eye contact and smile more.
What are the potential problems associated with the use of punishment?
Escape, aggression, apathy, abuse, and imitation of the abuser
One potential problem associated with the use of punishment is escape, explain
You can escape without actually fleeing, humans do this by “tuning out”.
People also escape or avoid punishment by cheating and lying, and the ultimate escape is suicide
One potential problem of using punishment is to use aggression
An alternative to escaping punishment is to attack those who punish. Aggression is particularly likely when escape is impossible and is often an effective way of exerting control over those who punish
