The secular trend of intelligence test scores in the present century: The Danish experience - ScienceDirect

 The secular trend of intelligence test scores in the present century: The Danish experience - ScienceDirect 
https://www.sciencedirect.com/science/article/abs/pii/S016028962100009X

Highlights

•
Changes in mean intelligence test scores were minimal in Denmark in 2006–2019.
•
A change in the format of the intelligence test resulted in a sudden drop in scores.
•
Neither changes in parental age, dysgenics, or immigration can explain the findings.
•
Changes in sample composition may conceal a true decline in intelligence test scores.

Abstract
The present register-based study investigated the secular trend of intelligence test scores during the period from 2006 through 2019 in a Danish population-representative sample, as well as whether the observed trend could be explained by changes in parental age, dysgenics, and immigration or changes in the format of the intelligence test and sample characteristics. The study population consisted of all Danish men appearing before a draft board during the study period (N = 400,288). Intelligence test scores were obtained by the use of Børge Priens Prøve, typically at age 19. For each of the included draft board cohorts, the intelligence test score mean and standard deviation were estimated. The results showed that changes in mean intelligence test scores were minimal during the study period. A slight decline was observed from 2006 to 2010. Furthermore, there was a drop of 1.5 IQ points from 2010 to 2011, which coincided with the change in the format of the intelligence test from paper-and-pencil to computer-based, but there was essentially no change after 2011. Neither changes in parental age, dysgenics, or immigration seem to have influenced the observations. However, changes in sample composition may conceal a true decline in intelligence test scores given that a larger proportion of individuals with low intelligence seems to be exempted from testing. In conclusion, the study findings suggest no systematic change in intelligence test scores during the last decade, but due to changes in sample composition, it cannot be excluded that there has been a negative secular trend.

No negative Flynn effect in France: Why variations of intelligence should not be assessed using tests based on cultural knowledge - ScienceDirect

https://www.sciencedirect.com/science/article/pii/S0160289620300908

Abstract
In 2015, Dutton and Lynn published an account of a decrease of intelligence in France (negative Flynn effect) which had considerable societal impact. This decline was argued to be biological. However, there is good reason to be skeptical of these conclusions. The claim of intelligence decline was based on the finding of lower scores on the WAIS-III (normed in 1999) for a recent sample, but careful examination of the data suggests that this decline was in fact limited to subtests with a strong influence of culture-dependent declarative knowledge. In Study 1, we re-analyzed the data used by Dutton and Lynn (2015) and showed that only subtests of the WAIS primarily assessing cultural knowledge (Gc) demonstrated a significant decline. Study 2 replicated this finding and confirmed that performance was constant on other subtests. An analysis of differential item functioning in the five subtests with a decline showed that about one fourth of all items were significantly more difficult for subjects in a recent sample than in the original normative sample, for an equal level of ability. Decline on a subtest correlated 0.95 with its cultural load. These results confirm that there is currently no evidence for a decrease of intelligence in France, with prior findings being attributable to a drift of item difficulty for older versions of the WAIS, due to cultural changes. This highlights the role of culture in Wechsler's intelligence tests and indicates that when interpreting (negative) Flynn effects, the past should really be treated as a different country.

Abstract
Although performance validity tests (PVTs) are an integral element of neuropsychological assessment, most PVTs have historically been restricted to the memory domain. The Dot Counting Test (DCT) is a nonmemory PVT shown to reliably identify invalid performance. Although several traditional and abbreviated scoring methods have been derived, no study to date has directly compared the available scoring approaches within a single sample. This cross-sectional study cross-validated 4 different DCT scoring approaches, including the traditional rounded E-score proposed within the manual, an unrounded E-score, and 2 abbreviated scoring procedures based on 4- and 6-card versions (DCT-4 and DCT-6, respectively) in a diverse mixed clinical neuropsychiatric sample (N = 132). Validity groups were established by 5 independent criterion PVTs (102 valid and 30 invalid). Receiver operating characteristic curve analyses yielded significant areas under the curve (AUCs = .84−.86) for the overall sample, with sensitivities of 50%–67% at ≥ 89% specificity. The DCT scores had outstanding classification accuracy (AUCs ≥ .92; sensitivities = 80%−83%) in the unimpaired group and excellent classification accuracy in the impaired group (AUCs = .79−.81; sensitivities = 43%−60%). Whereas negligible differences emerged between the 4 scoring methods for the cognitively intact group, the DCT-4 showed notably stronger psychometric properties among the overall sample in general and the mild cognitive impairment group in particular. Results corroborate previous findings suggesting that the DCT is a robust PVT, regardless of the employed scoring procedure, and replicate support for the abbreviated DCT-4 as the recommended validity indicator.

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.

Abstract

In 1986, the USSC ruled that it was a violation of the Eighth Amendment to the Constitution (cruel and unusual punishment) to execute someone who was 'insane'. (Ford v. Wainwright) In capital cases, a sentencing proceeding has, for many years, consisted of a jury hearing 'aggravating factors' from the state and 'mitigating factors' from the defense. Defense attorneys are now able to proffer someone's mental health history as a possible mitigating factor in capital cases, arguing that the mental illness played some role in the commission of the crime, and that therefore, the defendant should be sentenced to life imprisonment rather than death. A case called Eddings v. Oklahoma (1982) argued in front of the USSC resulted in a finding that the defense is entitled to use any possible mitigating evidence in a capital trial. Of course, the prosecution wants to present a strong case for capital punishment and therefore will present aggravating factors that include the defendant's propensity for violent behavior. Unfortunately, all too often these predictions of dangerousness are made in expert testimony where the expert is unaware of the real limitations documented in the research of predicting future violent behavior. In 2002, the USSC ruled that it was unconstitutional (again Eighth Amendment violation) to execute a mentally retarded defendant (Atkins v. Virginia). Unfortunately, several individual states adopted rather idiosyncratic definitions of mental retardation and some allowed the artificial inflation of I.Q. scores based on testimony that it was an 'ethnic adjustment'. This chapter describes some of the ways mental health professionals can work in death penalty clinics with defense attorneys or with state prosecutors on these cases.
