The goal of this post is to help you think like a scientist when it comes to evaluating questionable claims.

To support a causal claim, a study must meet three essential criteria: covariance, temporal precedence, and internal validity.

Interrogating association claims means asking three core questions: Were the variables measured well (construct validity)? Can the results be generalized to other populations (external validity)? And is the association statistically strong, significant, and precise (statistical validity)?

The four big validities offer a comprehensive toolkit for evaluating psychological research. Construct validity ensures that variables are accurately measured or manipulated. External validity tells us whether the results generalize. Statistical validity ensures the numbers are trustworthy. Internal validity confirms that cause-and-effect relationships are legitimate.

Association claims are foundational to psychological research because they help us identify variables that are connected and warrant further investigation. While they cannot prove causality, they provide essential groundwork for asking deeper questions.

Understanding how each variable was operationalized helps you evaluate whether results can be compared or generalized. It also helps you decide whether the measure actually reflects the concept you’re interested in.

At its core, ADHD is not about lacking attention—it's about struggling to control it.

Encephalopathy presents with polymorphic delta activity—delta waves that vary in shape and amplitude—over cortical areas.

Traveling waves in electroencephalography (EEG) represent coordinated patterns of electrical activity that move systematically across the cortex.

Diffuse slowing reflects a global disturbance of cortical–subcortical coupling and is therefore considered a biomarker of cerebral dysfunction rather than a discrete lesion.

EEG biomarkers offer incremental validity over behavioral observation alone.

IEDs are not incidental EEG findings, but markers of transient cortical dysfunction that disrupt cognition, emotion, and behavior.

Quantitative EEG (qEEG) normative databases can reveal the key parts of a network that need training and the required direction.

Dr. Davis wrote this frequently asked neurofeedback questions post as a resource for staff training and your clinic website.

Spindling excessive beta (SEB) represents a critical neurophysiological marker of cortical dysregulation identifiable on the EEG.

Breathing ensures healthy CO2 levels. The main functions of breathing are gas exchange and acid-base (pH) regulation.

I wrote this post to clear up confusion about frequency and amplitude, and give you a basic format for thinking about the EEG signal.

The IQCB guidelines formalize data collection, inspection, and analysis procedures to improve qEEG reliability and clinical acceptance.

The temporal and parietal lobes are the earliest affected, and the frontal and occipital lobes are the latest.

ADHD and ODD are distinct disorders with unique causes, symptoms, and treatment needs.
