Reinforcer choice as an antecedent versus consequence

Area of Science:

• Behavioral psychology
• Developmental psychology
• Autism Spectrum Disorder research

Background:

• Understanding motivation in children with autism spectrum disorder (ASD) is crucial for effective interventions.
• Choice-making opportunities are known to influence engagement and behavior in various populations.
• Previous research suggests reinforcement procedures can be tailored to individual preferences.

Purpose of the Study:

• To investigate the impact of antecedent versus consequent reinforcement choice on task responding in children with autism.
• To determine if children with autism prefer choosing reinforcement before or after task completion.
• To examine how varying response requirements interact with reinforcement choice conditions.

Main Methods:

• Four children diagnosed with autism spectrum disorder participated in the study.
• Participants were presented with opportunities to choose preferred stimuli either before (antecedent choice) or after (consequent choice) task completion.
• The response requirement for reinforcement was systematically increased within each session.

Main Results:

• Two out of four children demonstrated higher levels of task responding when reinforcement choice was provided as an antecedent to task completion.
• Three out of the four children exhibited a preference for the antecedent choice condition over the consequent choice condition.
• The study observed the effects of systematically increasing response requirements on behavior under different choice conditions.

Conclusions:

• Providing reinforcement choice as an antecedent to task completion may be a more effective strategy for increasing task responding in some children with autism.
• Children with autism may prefer having control over reinforcement selection prior to engaging in a task.
• These findings have implications for designing individualized and motivating behavioral interventions for autism.
