Neuropsychological assessment methodology revisited: metatheoretical reflections

Area of Science:

• Neuropsychology
• Philosophy of Science
• Cognitive Neuroscience

Background:

• Metatheoretical assumptions shape research methodologies and assessment strategies in neuropsychology.
• The relationship between psychological and physiological variables is influenced by these underlying philosophical assumptions.
• Understanding these connections is crucial for advancing the field.

Purpose of the Study:

• To illustrate the link between metatheory and methodology in neuropsychology.
• To re-examine the classic Double Dissociation (DD) procedure.
• To explore how DD can be interpreted through different metatheoretical lenses.

Main Methods:

• Revisiting the Double Dissociation (DD) procedure.
• Analyzing DD within localizationist and modular brain views.
• Interpreting DD through the generalized neuro-lens model.
• Connecting to systemic-network perspectives and ecological validation.

Main Results:

• Double Dissociation (DD) can be understood as supporting either brain modularity or a systemic-network view.
• The neuro-lens model offers a framework compatible with systemic-network perspectives.
• This approach facilitates ecological validation and integrates phenomenological insights.

Conclusions:

• Metatheory provides a foundation for understanding neuropsychological assessment strategies.
• Both localizationist and system science approaches can converge on a dynamical network view of the brain.
• Metatheory offers new avenues for reconciling different perspectives in neuropsychology.
