Scientific depth, direct writing, and disciplined inference.
John G. Grundy is a cognitive neuroscientist whose work examines how sustained experience reshapes attention, brain systems, and cognitive resilience across the lifespan.
Research background
My research focuses on experience-related neuroplasticity: how repeated cognitive demands alter attention, brain structure, neural function, and resilience. Bilingualism is one of the real-world models I use because managing multiple languages places sustained demands on selection, monitoring, switching, and adaptation. The consulting relevance is broader: this work requires separating plausible mechanisms from overextended claims, integrating evidence across very different methods, and identifying exactly where findings generalize and where they do not.
Across more than 40 peer-reviewed articles, I have worked with behavioral methods, EEG and event-related potentials, structural and functional neuroimaging, multivariate analysis, cognitive aging, and theory development. My work has appeared in journals including PNAS, NeuroImage, Cognition, Developmental Science, Human Brain Mapping, and Bilingualism: Language and Cognition.
Why that matters for diligence
Scientific review requires more than finding papers that mention the right concept. It requires determining whether the operational definitions, methods, comparisons, analyses, and inferential steps support the claim being made, and whether the result is likely to survive outside the setting in which it was produced.
My reviews are therefore structured around claim architecture: what is asserted, what must be assumed, which evidence is relevant, how strong the inference is, what credible alternatives exist, and which uncertainties matter to the decision.
Independent scope
This consulting service is offered independently. ERN Institute and the Journal of Experience-Related Neuroplasticity are separate scholarly initiatives. A consulting engagement does not imply endorsement by ERN Institute, its journal, or any affiliated scholar.
Working style
- Direct conclusions without overstating certainty
- Clear separation of established evidence, extrapolation, and speculation
- Attention to mechanisms and boundary conditions, not only headline effects
- Written outputs that can be retained, circulated, and scrutinized
- Scope discipline and transparent limits
The strength of the conclusion should never exceed the strength of the evidence.
That principle governs both the research and the consulting work.
