Reward Devaluation in Autistic Children and Adolescents with Complex Needs: A Feasibility Study

Area of Science:

• Neuroscience
• Developmental Psychology
• Behavioral Science

Background:

• Reward processing differences exist in autistic individuals without learning disabilities.
• Limited research explores reward processing in autistic individuals with complex needs.
• Understanding motivation is crucial for educational and intervention strategies.

Purpose of the Study:

• Assess the feasibility of an adapted reward devaluation paradigm for autistic individuals with complex needs.
• Investigate behavioral changes in response to reward value shifts in this population.
• Contribute to understanding fundamental learning processes in underrepresented autistic groups.

Main Methods:

• Adapted reward devaluation paradigm using a touchscreen laptop.
• Presented visual cues triggering video, music, or physical rewards.
• Devalued one reward through abundant presentation to assess motivational changes.
• Included 27 autistic children/adolescents with complex needs and 20 typically developing children.

Main Results:

• Participants showed decreased interest in devalued video and music rewards.
• The experimental setup was feasible for individuals with complex needs.
• Recommendations for using physical rewards were noted.
• Autistic participants with complex needs demonstrated goal-directed behavior.

Conclusions:

• It is feasible to develop experimental paradigms for studying learning in autistic individuals with complex needs.
• Findings suggest autistic individuals with complex needs exhibit adaptive goal-directed behavior.
• This research can inform educational and intervention strategies for underrepresented autistic populations.
