Welcome to Green's Publishing

We produce tests which help in discriminating between genuine cognitive impairment versus feigned impairment or results that are unreliable for some other reason (e.g. lack of engagement in testing).  These tests are used by neuropsychologists in 24+ countries and all 50 States of the USA.  They are widely used in the US Military and in the VA system.  They are available in many different languages.  The author, Dr. Paul Green, has published many papers in professional journals and book chapters, reporting the extensive research on which the tests are based.  In keeping with the fact that this is science, not religion, there are many independent replication studies, spanning several different countries, as shown in the bibliography (also under “References” or “Background” from the menu above).

Obituary for Dr. Paul Green

It is with heavy hearts that we announce the passing of Dr. Paul Green on August 15, 2020 after a valiant battle with metastatic prostate cancer.  Click here for a link to his obituary and a video of his funeral service.  We will continue to provide full support for his tests as we have done for the past 25+ years (including the past 4 years while Dr. Green was mainly retired).

The Advanced Interpretation (AI) program automatically extracts all data from the WMT, MSVT, NV-MSVT and MCI.  It lays out the data in an automated way and also applies the principles used to interpret data from these tests.

Those who are very experienced in using these tests find the AI program helpful because it does all the little calculations for them and saves the professional a lot of time.

Newcomers find that the AI program puts them on a fast learning curve, giving them added confidence.

Using a simple flow chart, it shows and applies the steps in interpreting results from the WMT, MSVT, and NV-MSVT.  A step-by-step decision process is laid out visually to check all the different criteria and come to a conclusion.  Thus, rules of interpretation are operationalized and objective.

Various graph options are available, including one that searches all comparison groups to find the groups with test curves most similar to the current case.

High specificity even in dementia and mentally handicapped children

People with dementia are of major importance in studying effort tests.  The reason is that they are more cognitively impaired than almost all other groups.  Therefore, they face the highest risk of being classified as poor effort when they are actually trying their best.  Children with a FSIQ below 70 are also important to study for the same reasons.  If we can achieve extremely few false positives for poor effort in these samples, which we can, then it follows that those groups with less impairment will also have very few false positives (e.g. adults with mild brain injury).

Q) Which effort tests can achieve 95% or 100% specificity in dementia and also in developmentally disabled children?

A) Most effort tests cannot do so.  The outcome of such tests (e.g. TOMM, CARB, ASTM) is only a pass or a fail and many people with dementia cannot pass.  Lowering the cut-off does not solve the problem.  However, the WMT, MSVT & NV-MSVT produce specific profiles in dementia, which are not the same as those arising from poor effort in people feigning dementia.  As a result, all three tests can each achieve 95% or 100% specificity in dementia and also in developmentally disabled children, including those with mental retardation.  Using the WMT, MSVT and NV-MSVT in combination does not lower specificity in those with genuine very severe impairment (e.g. dementia) but it enhances sensitivity to poor effort.  If we know that a test has extremely high specificity in very impaired people, then when someone fails it, they are either very severely impaired, which will usually be obvious, well documented and clinically evident, or their effort is poor.  The emphasis within this approach is in avoiding false positives at all costs.

NV-MSVT vs. TOMM

Many people will pass TOMM but fail the NV-MSVT and we can prove that these are not false positives for the NV-MSVT.

The latter study has already been independently replicated by Dr. Jehle, using data from Dr. Gervais.  Dr. Jehle is a U.S. Army Neuropsychologist, who is totally independent of both Dr. Gervais and Dr. Green.  Neither Dr. Jehle nor Dr. Gervais have any vested interests in the NV-MSVT or other Green’s Publishing tests.

Our programs makes it easy for you to contrast scores in a single case with any of the comparison groups, using graphs and report tables.

The AI program contains many more comparison groups than the original WMT, MSVT, NV-MSVT and MCI programs. It also converts WMT Free Recall and Long Delayed Free Recall scores to T-scores by age, gender and education.
