Operant Applications

Operant Conditioning at Home

Operant Conditioning at Home

• Operant conditioning: Consequences shape behavior.

• Parents: Major influence on children's learning and development.

• Neglect: Lack of attention and response → Poor development.

• Key idea: Children learn through reinforcement and interaction.

Four Areas of Child Development

Four Areas of Child Development

1. Language Development

• Parents reinforce sounds that resemble words.

• Shaping: Babbling → Words → Sentences.

• More instruction and practice → Better language skills.

2. Self-Control

• Self-control: Learning to resist immediate rewards.

• Can be taught through instruction and reinforcement.

• Example: Waiting for a larger reward instead of taking a smaller one now.

3. Persistence

• Persistence: Continuing despite difficulty.

• Reinforcing effort → Greater persistence.

• Learned industriousness: Learning not to give up.

4. Behavior Management

• Reinforcement: Strengthens desirable behavior.

• DRI: Reinforce incompatible behavior.

• DRL: Reinforce lower rates of unwanted behavior.

• Time Out: Removes access to reinforcement temporarily.

Operant Conditioning in Treatment

Operant Conditioning in Treatment

• Operant learning: Uses consequences to change behavior.

• Clinical uses: Treating self-injury, delusions, and paralysis.

• Key idea: Reinforcement can change behaviors linked to medical disorders.

Self-Injurious Behavior

Self-Injurious Behavior

• Self-injury: Behaviors that cause harm to oneself.

• Lovaas & Simmons (1969): Showed punishment could stop self-injury.

• DRI: Reinforce behavior incompatible with self-injury.

  • Example: Playing with a ball instead of hitting oneself.

• Finding: DRI reduced self-injury by over 90% in one study.

• Key idea: Reinforcement can reduce self-injury without punishment.

Attention & Self-Injury

Attention & Self-Injury

• Carr & McDowell (1980): Studied a boy's excessive scratching.

• Finding: Parental attention reinforced scratching.

• Ignoring scratching → Scratching decreased.

• Giving attention → Scratching increased.

• Treatment: Time Out + reinforcement for fewer sores.

• Result: Scratching decreased significantly.

Delusions

Delusions

• Delusions: Strong false beliefs.

• Key idea: Reinforcement can maintain or reduce delusional behavior.

• Layng & Andronis (1984): Delusional behavior gained staff attention.

• Alford (1986): Reinforcing doubt reduced confidence in a delusion.

• Important: Delusions can have biological causes, but consequences can affect their expression.

Goldiamond's Paradox

Goldiamond's Paradox

• Goldiamond's Paradox: Unusual behavior may earn reinforcement even when normal behavior does not.

• Example: A patient receives attention only when acting strangely.

• Key idea: Reinforcement can unintentionally maintain problem behavior.

Paralysis & Rehabilitation

Paralysis & Rehabilitation

• Edward Taub: Studied recovery of movement after injury.

• Learned nonuse: Avoiding an injured limb despite some remaining ability.

• CIMT (Constraint-Induced Movement Therapy):

  • Restrict use of the healthy limb.

  • Force practice with the affected limb.

  • Use shaping and feedback to improve movement.

• Finding: CIMT improved movement in stroke patients.

Operant Conditioning at Work

Operant Conditioning at Work

• Operant conditioning: Uses consequences to improve worker behavior.

• Goals: Increase productivity, reduce costs, improve safety.

• Key idea: Reinforcement can benefit both workers and employers.

Performance Feedback

Performance Feedback

• Feedback: Telling workers how well they perform.

• Positive feedback: Can improve performance.

• Thorndike: Showed that feedback improved accuracy.

• Harrison (2009): Feedback reduced managers' overtime by about 40%.

• Key idea: Feedback alone can improve performance.

Feedback + Reinforcement

Feedback + Reinforcement

• Feedback + rewards: Often more effective than feedback alone.

• Bonuses: Reinforce good performance.

• Truck drivers: Feedback + bonuses increased productivity.

• Roofers: Feedback + bonuses reduced labor costs by 64%.

• Key idea: Rewarding performance strengthens desired behavior.

Workplace Safety

Workplace Safety

• Operant conditioning: Can reduce workplace accidents.

• Feedback: Helps workers follow safety rules.

• Reinforcement: Encourages safe behavior.

• Finding: Daily feedback improved safety compliance.

Operant Conditioning in Zoos

Operant Conditioning in Zoos

• Operant conditioning: Uses reinforcement to train animals.

• Purpose: Improve animal care, safety, and well-being.

• Key idea: Training reduces the need for force or restraints.

Veterinary Care

Veterinary Care

• Gary Wilkes (1994): Trained an aggressive elephant for foot care.

• Shaping: Reinforced small steps toward lifting its foot.

• Clicker: Conditioned reinforcer signaling a reward.

• Result: Elephant voluntarily allowed foot treatment.

• Benefit: Safer for animals and caregivers.

Stereotypic Behavior

Stereotypic Behavior

• Stereotypic behavior: Repetitive, often purposeless behavior.

• Examples: Pacing, swaying, rocking.

• Cause: Often linked to boredom or limited stimulation.

• Solution: Environmental enrichment.

Environmental Enrichment

Environmental Enrichment

• Enrichment: Making an animal's environment more stimulating.

• Hal Markowitz: Used operant conditioning to improve zoo animals' lives.

• Example: Bears searching for hidden food.

• Result: More natural behavior, less stereotypic behavior.
