VI. Conclusion

 

The database we have considered here is infinitely depressing. There was only actual relief in 12.4% of the cases that raised Atkins issues, and this grouping of nine cases includes two in which the defendant died before the final relief could be implemented. What it reveals is a Court with little or no interest in the thoughtful opinions of Justice Stevens in Atkins and of Justice Kennedy in Hall. The science is ignored, and the jurisprudence is ignored. Baseless fears of undetected malingering, the mindless use of lay stereotypes of what “looks like” remorse, and the corrupt employment of “ethnic adjustments” to lawlessly raise IQ scores making certain minority defendants improperly eligible for execution all are reflected in the cases decided by the Fifth Circuit. Certainly, the earlier conclusion reached by Professor John Blume and his colleagues (in their empirical study of all Atkins claims) – that “Atkins is not evenhandedly protecting those it was designed to protect”296—rings as true today as it did when written eleven years ago. On the other hand, the cases reveal important potential strategies for defense counsel: (1) It is essential that allegations of malingering be vigorously rebutted through expert testimony; (2) even though the Fifth Circuit has not yet acknowledged its scientific validity, the Flynn effect must be brought to the Court’s attention, (3) the defendant should be given a WAIS test, and the WISC test must be avoided, (4) the use of lay stereotypes of “showing remorse” must be firmly discredited. If these are all done, then there is at least some chance that Atkins and its progeny will be given life in subsequent cases.

Objective

This paper summarizes the findings of the Neuropsychological Norms for the U.S.-Mexico Border Region in Spanish (NP-NUMBRS) Project and offers a roadmap for future research.

Methods

The NP-NUMBRS project represents the largest and most comprehensive co-normed neuropsychological battery to date for native Spanish-speaking healthy adults from the U.S. (California/Arizona)-Mexico borderland region (N = 254; ages 19–60 years). These norms provide demographic adjustments for tests across numerous domains (i.e., verbal fluency, processing speed, attention/working memory, executive function, episodic memory [learning and delayed recall], visuospatial, and fine motor skills).

Conclusions

This project: 1) shows that the NP-NUMBRS norms consistently outperformed previously published norms for English-speaking non-Hispanic (White and African-American) adults in identifying impairment; 2) explores the role of Spanish-English bilingualism in test performance; and 3) provides support for the diagnostic validity of these norms in detecting HIV-associated neurocognitive impairment. Study limitations include the limited assessment of sociocultural variables and generalizability (e.g., other Latina/o populations, age limit [19 − 60 years]). Future research is needed to: 1) investigate these norms with U.S.-dwelling Spanish-speakers of non-Mexican heritage and other clinical subpopulations; 2) expand coverage of cognitive domains (e.g. language, visuospatial); 3) develop large normative datasets for children and older Latina/o populations; 4) examine how sociocultural factors impact performance (e.g., bilingualism, acculturation); 5) investigate these norms' diagnostic and ecological validity; and 6) develop norms for neurocognitive change across time. It is hoped that the NP-NUMBRS norms will aid researchers and clinicians working with U.S.-dwelling Spanish-speakers from the U.S.-Mexico borderland to conduct research and evidence-based neuropsychological evaluations in a more culturally responsive and ethical manner.
