Understanding Executive Function Skills

• Definition: Executive function refers to the brain's ability to activate, organize, integrate, and manage other cognitive functions, enabling planning, foresight, and real-time self-adjustment.
• Connection to ADHD: Executive function impairments are considered highly interrelated to ADHD symptoms, particularly regarding the inability to self-regulate and delay responses.
• Russell Barkley’s Model: Focuses on the root cause being an inability to self-regulate. He categorizes executive function into four areas:
  • Nonverbal working memory
  • Internalization of speech (verbal working memory)
  • Self-regulation of affect, motivation, and arousal
  • Reconstitution (planning and generativity)
• Tom Brown’s Model: Proposes six integrated "clusters" of executive function; impairments in these areas often appear together:
  • Organizing, prioritizing, and activating for tasks
  • Focusing, sustaining, and shifting attention
  • Regulating alertness, sustaining effort, and processing speed
  • Managing frustration and modulating emotions
  • Utilizing working memory and accessing recall
  • Monitoring and self-regulating action
• Impact: Deficits in these areas significantly hinder an individual's ability to initiate, maintain focus on, and complete tasks.
