Revisiting Drive Reduction Theory: Motivational Foundations and Therapeutic Implications for Autism Spectrum Disorder

This review paper provides a short overview of Clark Hull’s Drive Reduction Theory (DRT) with its equation, and its relevance to our current understanding of behavioral patterns in children with autism spectrum disorder (ASD). DRT proposes that conative behavior is motivated by the need to reduce the internal tension resulting from unmet physiological or psychological needs. Although contemporary frameworks, such as Self-Determination Theory and Expectancy-Value Theory, have expanded the motivational constructs, DRT remains valuable for its systematic and quantifiable approach. Applying DRT to ASD reveals that repetitive movements, sensory-seeking or sensory-avoidant behaviors, insistence on sameness, and engagement in restricted interests may function as drive-reducing strategies aimed at restoring homeostasis. This interpretation supports more empathetic and targeted intervention design. The paper has gone on to discuss briefly the varied therapeutic applications, including sensory-based strategies, structured routines, interest-based learning strategies, and family-centered approaches that leverage intrinsic motivational drives. Overall, DRT offers a useful theoretical bridge between classical motivation science and contemporary therapeutic practice for children with ASD.
