EARLY COGNITIVE TESTING …
• Assessed one individual at a time, often in extraordinary circumstances
• Used physical objects or pen and paper responses that had to be set up,
monitored, and scored by hand.
• Were based on performance and intuition and had only loose connections with
the brain.

IS WEB-BASED TESTING VALID?
• High correlation between in-lab and at-home
testing (r > 0.85).
• No significant difference between scores collected
in-lab vs. at-home.
• Both healthy and clinical populations.
• Interactive tutorials and practice rounds can
increase reliability of unsupervised testing.
• Database allows for detection of invalid results.

APA SPONSORED WEBINAR SERIES
IS INTELLIGENCE UNITARY?
• An unresolved question after more than 100 years of study—can modernized
cognitive testing help?
• The study used 12 computerized cognitive tasks, based on well-established
paradigms, and validated through decades of research
• Spanning different cognitive domains (planning, reasoning, attention, working
memory, verbal ability)
• Given to two cohorts: a large internet cohort, and smaller neuroimaging cohort
APA SPONSORED WEBINAR SERIES
THE NEURON STUDY
• Internet cohort:
• Over 46,000 participants with complete data on all
12 tasks at home
• Factor analysis of behavioral data
• Neuroimaging cohort:
• 16 healthy participants completing the same 12
tasks in an fMRI scanner
• Factor analysis of brain imaging data

SO, IS INTELLIGENCE UNITARY?
COMPUTERIZED TESTS HELP PROVIDE ANSWERS
• An adequate model of the distribution of test
scores in the population requires at least 3 factors.
• These factors:
• Are associated with distinct specialized brain networks,
• Are recruited in combination for specific cognitive tasks,
• And, correlate with demographic variables in a dissociable
manner (e.g., age, lifestyle, mental health).

2010-2021: A USEFUL SCIENTIFIC
FRAMEWORK
APA SPONSORED WEBINAR SERIES
FROM 50,000 PARTICIPANTS TO
INDIVIDUAL PATIENTS
• Additional studies and testing have resulted in over
80,000 people in the Cambridge Brain Sciences database.
• Represents the general healthy population and can be
broken down by age but maintain a large normative
sample.
• Comparisons to the database provide age-matched
percentiles and standard scores for any individual.

APPLYING MODERN COGNITIVE
TESTING TO HEALTHCARE
• Healthcare often relies on subjective reports, lengthy and costly
neuropsychological evaluations, or tests only appropriate for some patients.
• Computerized testing takes less time, is automatically scored, can be selfadministered, and is instantly compared to normative data.
• Healthcare providers can use the same tests refined over 35+ years to assess
patient cognition at baseline, during treatment, and through long-term
monitoring.

TASK DEMONSTRATION: DOUBLE
TROUBLE
A TEST OF RESPONSE INHIBITION
• A “double” variant on the Stroop task
(Stroop, 1935).
• Patients must focus on the color of the
word at the top and choose the word at
the bottom that describes it.
• Three difficulty levels: congruent,
incongruent, or doubly incongruent,
depending on whether or not the color
of each word matches the color that it is
written in.

“If Hillary's climbers were sitting in their tents today,
they would not be sorting cards. They would be logged
on to the internet while their brains were monitored in
real time and compared to the brains of millions of
others at sea level, for signs that altitude and fatigue
were affecting their cognitive function. We’ve come a
long way in 60 years.”

QUESTIONS & ANSWERS
APA SPONSORED WEBINAR SERIES
• How can psychological testing be best done now with remote telehealth?
• I'm curious about results obtained from individuals who have had SARS-CoV-2 and
recovered (cognitive tests predominantly).
• How are these cognitive tests becoming more culture-fair and applicable to persons
of color? Do they need to?
• What is the correlation between intelligence and success in typical measurements?
• How does this connect with the latest psychedelic research.
• How is intuition addressed?
• Will more advanced imaging techniques eventually make cognitive testing for
diagnosis obsolete?
