Russell Barkley's Model of Executive Functions
I cannot provide a comprehensive answer about Russell Barkley's specific model of executive functions based on the evidence provided, as none of the studies directly describe Barkley's theoretical framework in detail.
Limited Evidence Available
The provided evidence contains only one brief reference to Barkley's work:
- A 2004 study tested "Barkley's hybrid model of executive functions," which predicts that individuals with deficient inhibitory control should show impairment of executive functions 1
- This study found that effective executive functioning is associated with sufficient inhibitory control, providing partial support for Barkley's theory 1
What the Evidence Does NOT Contain
The evidence provided focuses primarily on:
- Physical activity interventions in preschoolers 2
- Vascular cognitive impairment assessment protocols 2
- OCD-related cognitive deficits 2, 3
- General executive function testing guidelines 4
- Broad definitions of executive functions from other researchers 5, 6, 7
None of these sources describe Barkley's specific conceptualization of executive functions beyond the single mention that his model emphasizes the relationship between behavioral inhibition and executive function 1.
General Executive Function Framework (Not Barkley-Specific)
Based on the available evidence, executive functions broadly encompass:
- Inhibitory control (behavioral inhibition) 2, 7, 1
- Working memory 2, 7
- Cognitive flexibility/shifting 2, 7
- Planning and problem-solving 7, 8
- Processing speed and activation 2
However, this represents a general consensus framework, not Barkley's specific model.
