A translational evaluation of transitions.

Area of Science:

• Behavioral Psychology
• Autism Spectrum Disorder Research
• Applied Behavior Analysis

Background:

• Transitions are often viewed as changes in reinforcement schedules, causing response pauses, especially from rich to lean schedules.
• In applied research, transitions are physical shifts that can trigger problem behaviors linked to escaping aversive events or seeking preferred ones.
• Existing research on transitions lacks focus on socially significant behaviors and contexts.

Purpose of the Study:

• To extend the understanding of transitions to socially significant behaviors and contexts.
• To evaluate a novel treatment for dawdling in children with autism spectrum disorder (ASD) during rich-to-lean transitions.
• To analyze the relationship between dawdling and lean reinforcement contexts.

Main Methods:

• Experiment 1 observed dawdling in three boys with ASD during physical transitions to lean reinforcement contexts.
• Experiment 2 implemented a treatment by shortening transition duration and programming unsignaled, probabilistic rich reinforcement in the upcoming context.
• Behavioral data on dawdling was collected and analyzed across both experimental phases.

Main Results:

• Dawdling was most pronounced during transitions to lean reinforcement contexts.
• The novel treatment significantly reduced dawdling duration and frequency.
• Shortening transition duration and introducing probabilistic reinforcement proved effective in mitigating dawdling behavior.

Conclusions:

• Dawdling during physical transitions in children with ASD is influenced by the shift to less preferred (lean) reinforcement contexts.
• A treatment combining reduced transition duration and programmed reinforcement is effective for addressing dawdling.
• Findings support the extension of reinforcement schedule principles to understand and treat socially significant transition-related behaviors in ASD.
