Module 4: Positive & Negative Punishment

Punishment: Definition & Characteristics

• Definition: Punishment is defined as when a response is followed immediately by a stimulus change that decreases the future frequency of that type of response.

  • Characteristics:

  • The decrease in response rate must occur for it to qualify as punishment.

  • Not every consequence that seems punishing is effective; the action's nature isn't the sole factor.

  • Example: Reprimands may not always lead to a decrease in behavior.

Positive Punishment

• Definition: Positive punishment occurs when the presentation of a stimulus (or the increase of an already present stimulus) immediately follows a behavior resulting in a decrease in the future frequency of that behavior.

  • Examples:

  • Stubbing your toe can serve as a form of positive punishment.

  • Reprimands can function as positive punishment in certain situations.

Negative Punishment

• Definition: Negative punishment occurs when the removal of an already present stimulus (or a decrease in its intensity) immediately follows a behavior and results in a decrease in the future frequency of that behavior.

  • Examples:

  • Turning your back on your food, leading to it being taken by a seagull.

  • Requires an Establishing Operation (EO) to be present; if an individual is full, they may not care if a seagull has taken their lunch.

Types of Punishers

• Punisher: A stimulus change that immediately follows a response and decreases the future occurrence of that type of behavior.

  • Categories:

  • Positive punishers

  • Negative punishers

  • Unconditioned punishers

  • Conditioned punishers

Unconditioned Punishers

• Definition: Also known as primary or unlearned punishers; these are stimuli whose presentation functions as punishment without having been paired with any other punishers.

  • Origin: Considered a product of evolutionary history, thus all members of a species are likely to find the same unconditioned punishers punishing.

  • Examples:

  • Physical trauma

  • Odors/tastes (e.g., lemon juice)

  • Physical restraint

  • Extreme muscular effort

Conditioned Punishers

• Definition: Also known as secondary or learned punishers; these stimuli function as punishment as a result of a person’s conditioning history.

  • Mechanism: Acquired through stimulus-stimulus pairing with one or more unconditioned or previously conditioned punishers.

  • Example: Pairing a shock with a tone will condition the tone as a punisher.

Verbal Analog Conditioning

• Conditioned punishers that occur without physical pairing.

  • Example: A parent telling a child that touching the stove will result in a burn, leading to a decrease in the child's reaching behavior.

Generalized Conditioned Punishers

• Definition: Stimuli that have been paired with numerous forms of unconditioned and conditioned punishers.

  • Examples:

  • Reprimands

  • Disapproving gestures (e.g., scowls, frowns)

  • Loss of privileges previously paired with other punishments.

Critical Point

• Punishers are defined by their function, meaning a stimulus may serve as either a punisher or reinforcer, depending on context.

  • Example: Food can function as a punisher if an individual is already full.

  • Example: A smiley face sticker might decrease a student's productivity.

Discriminative Effects of Punishment

• Discriminative Stimulus for Punishment (SDp): A stimulus condition in the presence of which a response has a lower probability of occurrence than it does in its absence due to response-contingent punishment delivery.

  • Example: SDp (Mom is cooking dinner), Response (going into the kitchen for a snack), SP (Mom yells at me); leads to a decreased likelihood of snacking during cooking.

Recovery from Punishment

• Likely to occur under the following conditions:

  • When the behavior is also being reinforced.

  • When the punishment is mild.

  • When the individual discriminates that the punishment is no longer active.

The Effectiveness of Punishment

• Factors Influencing Effectiveness:

  • Immediacy: Maximum suppressive effects occur when the punisher follows the target response immediately.

  • Intensity: A positive correlation exists between the intensity of the punisher and the suppression of the response.

  • A negative correlation is found between the intensity of the punishing stimulus and recovery from punishment.

  • High intensity stimuli presented at low intensity then increased may become ineffective as punishers.

  • Schedule or Frequency: Continuous punishment schedules maximize suppressive effects (FR1), while intermittent punishment might be effective under specific conditions.

  • Reinforcement for Target Behavior: Greater effectiveness of punishment occurs when the reinforcement for the behavior can be reduced; total withholding results in extinction, not punishment.

  • Reinforcement for Alternative Behavior: Allowing access to an alternative behavior that fulfills the same function as the behavior being punished enhances effectiveness.

Possible Side Effects of Punishment

• Emotional and aggressive behaviors may arise (respondent or operant).

• Escape and avoidance behaviors may manifest, such as lying, cheating, or hiding.

• Behavioral Contrast: A change in one component of a multiple schedule leads to an increase or decrease in response rates in the opposite direction on the unaltered component.

• Punishment can model undesirable behaviors, e.g., spanking.

• Punishment may be overused due to negative reinforcement of the punishing agent's behavior, leading to temporary cessation of the undesired behavior affecting another person.

Positive Punishment Interventions

• Reprimands: Quick verbal corrections (e.g., “No,” “Stop,” “Don’t do that”) immediately following the target behavior.

• Response Blocking: Physically intervening as soon as the target behavior begins; often used for self-injurious or self-stimulatory behaviors.

• Response Interruption & Redirection: Interrupting stereotypic behavior at onset and redirecting to a high-probability behavior.

  • Types:

    • Motor RIRD (e.g., physical redirection).

    • Vocal RIRD (e.g., verbal instructions).

• Contingent Exercise: Engaging in a behavior not directly related to the problem behavior.

• Overcorrection: Involves two types:

  • Restitutional Overcorrection: Repairing damage from the problem behavior by restoring the environment to its original state and then improving it.

  • Positive Practice Overcorrection: Repeating a correct form of behavior or an incompatible behavior for a designated duration/number of responses.

  • Example: Wiping feet when tracking mud inside the home 5 times after muddying the floor.

Overcorrection Factors to Consider

• Type and severity of the problem behavior.

• Effects on the environment.

• Setting in which punishment occurs.

• Desired alternative behavior.

• Labor intensity of the procedure; overseer must not reinforce behavior.

• Resistance from individuals frequently engaging in problem behavior concerning compliance.

Guidelines for Using Punishment

• Appropriate when: serious harm results from problem behavior, reinforcement-based treatments fail, and reinforcers maintaining the problem behavior can't be identified or withheld.

• Effective and Appropriate Punishers: Conduct assessments measuring suppression, negative verbalizations, avoidance movements, escape attempts, or disruptions related to potential punishers.

• Use varied punishers in terms of quality and intensity; effectiveness may diminish with repeated use.

• Deliver punishment at the beginning of the behavioral sequence; punish as soon as the behavior starts.

• Maintain consistency in punishment delivery (initially, follow each instance at FR1).

• Gradually transition to intermittent punishment schedules.

• Mediate unavoidable delays in the response-to-punishment connection; strive to intervene if punishment cannot occur immediately.

• Supplement punishment with complementary interventions, combining differential reinforcement, extinction, and antecedent interventions.

  • DR Procedures: Include reinforcement and extinction components.

• Monitor and prepare for negative side effects, noting potential suppression of one behavior prompting increases in others. Daily data recording, graphing, and evaluation is essential.

Ethical Considerations

• Right to Safe & Humane Treatment: Ensures no physical, psychological, or social risks; therapeutic methods must be effective, compassionate, and responsive to individual needs.

• Least Restrictive Alternative: Less intrusive methods should be tried before punitive measures; restrictiveness varies based on procedural details.

• Generally acceptable procedures shouldn't cause pain or require medical attention and must align with typical societal norms.

• Right to Effective Treatment: Particularly significant for severe behaviors; punishment can be justifiable when it alleviates more severe consequences of habitual behavior.

• Policy, Procedure, Evaluation: Adhere to laws and ethics codes, ensuring all staff are properly trained and that each instance of behavior and punishment is recorded. Implement plans for generalization and maintenance, and obtaining necessary consent.

Comments on Punishment

• Punishment is vital for survival and learning; it occurs naturally in daily life.

• The need for more research into punishment approaches exists.

• Practical applications of punishment should be carefully considered, using unconditioned punishers only as a last resort, termed as a default technology.

Summary

• Positive punishment occurs when a response is followed by a stimulus change that reduces future frequency of similar behaviors.

• The definitive factor of punishment is the decrease in responding, not just the action or consequence's nature.

• Numerous ethical dimensions accompany the application of punishment, which should not deter its implementation altogether.

• Clinicians must prepare for potential side effects of punishment, ensuring comprehensive strategies for effective management.
