Changing preference from tangible to social activities through an observation procedure.

Area of Science:

• Behavioral Psychology
• Developmental Psychology
• Autism Spectrum Disorder Research

Background:

• Individuals with autism spectrum disorder (ASD) often show a preference for tangible or food reinforcers over social ones.
• Therapists frequently utilize tangible items or food as primary reinforcers for behavior modification in children with ASD.
• Understanding and shifting reinforcement preferences is crucial for effective social skills development in ASD.

Purpose of the Study:

• To investigate the effectiveness of observational conditioning in shifting preference from tangible items to social reinforcers in children with ASD.
• To determine if observing a peer select a social reinforcer could increase its desirability for participants.
• To assess the maintenance of preference changes following the intervention.

Main Methods:

• An observational conditioning procedure was employed where participants watched a peer interact with reinforcers.
• Participants observed a peer select an initially non-preferred social reinforcer over a highly preferred tangible item.
• Preference shifts were measured before and after the observational trials.

Main Results:

• All participants demonstrated a shift in preference towards the social reinforcer after the observational procedure.
• Preference changes were largely maintained, with one participant quickly re-establishing the preference after additional trials.
• The findings indicate that observational learning can effectively alter reinforcement hierarchies.

Conclusions:

• Observational conditioning is a viable procedure for modifying reinforcement preferences in children with autism spectrum disorder.
• This method offers a promising alternative or supplement to traditional reinforcement strategies in therapeutic settings.
• Further research can explore the long-term effects and broader applications of observational procedures in ASD interventions.
