Multiple studies have documented significant IQ gains over time, a phenomenon labeled the Flynn effect. Data from 20 industrialized nations show massive IQ gains over time, most notably in culturally reduced tests like the Raven's Progressive Matrices. To our knowledge, however, this is the first study to document the Flynn effect in a rural area of a developing country. Data for this project were collected during two large studies in Embu, Kenya, in 1984 and 1998. Results strongly support a… Expand

Generational gains on the Draw-a-Person IQ scores: A three-decade comparison from Turkey
Abstract In 1977 Draw-a-Person test was administered to fifth grade school children in a city and its surrounding rural villages in Turkey. In 2010, more than thirty years later, the test wasExpand

Findings include that IQ gains vary according to domain, are stronger for adults than children, and have decreased in more recent decades, while factors associated with life history speed seem mainly responsible for the Flynn effect’s general trajectory. Expand
The flynn effect in the caribbean : Generational change of cognitive test performance in dominica
Mental ability, as assessed by standardized tests, is not fixed in time. Large IQ gains have been recorded in many industrialized countries during the 20th century, but very little is known about IQExpand
Generational changes on the draw-a-man test: a comparison of Brazilian urban and rural children tested in 1930, 2002 and 2004.
This article analyses data for a sample of 499 children tested in 1930 and one equivalent sample of 710 children tested 72 years later, the largest gap ever considered, to find results consistent with both the cognitive stimulation and the nutritional hypotheses. Expand
A long-term rise and recent decline in intelligence test performance: The Flynn Effect in reverse
Abstract In the 1980s reviewed evidence indicated that, through the preceding decades of the last century, population performance on intelligence tests had been rising substantially, typically aboutExpand
IQ Gains in Argentina between 1964 and 1998.
The literature on IQ gains in Latin America is sparse. We estimate gains on Raven's Progressive Matrices in the city of La Plata (Argentina) between 1964 and 1998. The gains are robust at the top ofExpand
What Is Intelligence?: Beyond the Flynn Effect
Around their 18th birthday, basically all Dutch males born between 1934 and 1964 unknowingly took part in a study of the malleability of intelligence. When these young men appeared before the DutchExpand
Children’s performance on Raven’s Coloured progressive matrices in Portugal: The Flynn effect
Abstract The goal of this study was to examine how IQ changes (the Flynn effect) among school-aged children in Portugal behaved over a period of 25 years (1991, 2008 and 2016) that registered majorExpand
The Flynn Effect within Subgroups in the U.S.: Gender, Race, Income, Education, and Urbanization Differences in the NLSY-Children Data.
It is suggested that the NLSYC data can be used as a natural laboratory to study more subtle FE patterns within various demographic subgroups, and both the positive and the null findings are interpreted in relation to previous theoretical explanations. Expand
The end of the Flynn effect?: A study of secular trends in mean intelligence test scores of Norwegian conscripts during half a century
Abstract The present paper reports secular trends in the mean scores of a language, mathematics, and a Raven-like test together with a combined general ability (GA) score among Norwegian (male)Expand


Massive IQ gains in 14 nations: What IQ tests really measure.
Data from 14 nations reveal IQ gains ranging from 5 to 25 points in a single generation. Some of the largest gains occur on culturally reduced tests and tests of fluid intelligence. The NorwegianExpand
A long-term increase in the fluid intelligence of English children
It is reported here that in English children there has been an increase over the past 50 years, averaging 2.48 points per decade, in fluid intelligence, the mental power that underlies the acquisition of cognitive skills, rather than in crystallized intelligence, which represents the cognitive skills acquired in a particular culture.

IQ gains, WISC subtests and fluid g: g theory and the relevance of Spearman's hypothesis to race.

Human groups can make massive fluid g gains in a period too short to accommodate radical change in the speed and efficiency of neural processes, and not only a measure of fluid g but also inbreeding depression are shown to be correlated with IQ gains. Expand

A review of studies on the effect of iron deficiency on cognitive development in children.
It remains uncertain whether the poor development of iron-deficient infants is due to poor social backgrounds or irreversible damage or is remediable with iron treatment, and RCT of iron treatment are warranted especially in younger children. Expand

The author identifies critical flaws in recent critiques of the dilution position and concludes that dilution continues to provide the most promising explanation for why children with few siblings score higher on tests of cognitive skills than children with many siblings. Expand
