Problem behavior in autism spectrum disorders: A paradigmatic self-organized perspective of network structures

Area of Science:

• Neuroscience
• Complex Systems Science
• Psychiatry

Background:

• Autism spectrum disorder (ASD) is characterized by behavioral challenges, including acute agitation and aggressiveness, termed problem behaviors.
• These problem behaviors in ASD subjects have been observed to occur intermittently.

Purpose of the Study:

• To investigate the potential application of self-organized criticality (SOC) models in understanding problem behaviors within Autism Spectrum Disorder (ASD).
• To explore whether ASD psychopathology networks can be conceptualized as self-organized systems.

Main Methods:

• Analysis of behavioral data from ASD subjects exhibiting problem behaviors.
• Modeling of these behaviors using principles of self-organized criticality (SOC).

Main Results:

• Observed problem behaviors in ASD subjects demonstrated consistency with the theoretical framework of self-organized criticality (SOC).
• The intermittent "catastrophic events" (problem behaviors) appear necessary for maintaining a "critical equilibrium" within the system.

Conclusions:

• The self-organized criticality (SOC) model provides a viable framework for representing the network structures of psychopathology in ASD.
• ASD can be conceptualized as a complex self-organizing system where problem behaviors play a role in system regulation.
