Abstract The Flynn effect describes sustained gains in cognitive performance that have been observed in the past century. These improvements are not evenly distributed, with strong variations across regions or groups. To this effect, we report time and generational trends in IQ development in Romania. Using pooled repeated cross-sectional data ranging from 2003 to 2018 (N = 12,034), we used Hierarchical Age-Period-Cohort Models (HAPC) on data measured with the Multidimensional Aptitude Battery I...

Abstract Although Planning, Attention, Simultaneous and Successive (PASS) processing theory of intelligence has been argued to offer an alternative look at intelligence and PASS processes – operationalized with the Cognitive Assessment System – have been used in several studies, it remains unclear how well the PASS processes relate to academic achievement. Thus, this study aimed to determine their association by conducting a meta-analysis. A random-effects model analysis of data from 62 studies ...

Abstract Fluctuating body asymmetry is theorized to indicate developmental instability, and to have small positive associations with low socioeconomic status (SES). Previous studies have reported small negative associations between fluctuating body asymmetry and cognitive functioning, but relationships between fluctuating brain asymmetry and cognitive functioning remain unclear. The present study investigated the association between general intelligence (a latent factor derived from a factor ana...

Abstract Although digital transformations can help narrow existing gender gaps in labour market outcomes, this change depends, among several factors, on the extent to which females have the skills to make the most of new opportunities. An important such skill is problem solving. We examined gender gaps in cognitive and attitudinal dimensions of problem solving and how between-country differences in such gaps are related to societal level gender inequality. This study involved 237,115 students fr...

Abstract Via meta-analysis, we examined whether the heritability of intelligence varies across racial or ethnic groups. Specifically, we tested a hypothesis predicting an interaction whereby those racial and ethnic groups living in relatively disadvantaged environments display lower heritability and higher environmentality. The reasoning behind this prediction is that people (or groups of people) raised in poor environments may not be able to realize their full genetic potentials. Our sample (k ...

Abstract Complex Problem Solving (CPS) and reasoning are considered as correlated, but not equivalent ( Stadler, Becker, Godker, Leutner, & Greiff, 2015 ). However, empirical evidence for incremental validity of constructs beyond reasoning regarding CPS is scarce. This includes evidence for CPS self-concept (CPS SC; cf. Meisner, Greiff, Frischkorn, & Steinmayr, 2016 ). Strongest evidence would result from applying CPS scenarios as criteria that have been constructed to maximize correlations with...

Abstract Experts (Nmax = 102 answering) on intelligence completed a survey about IQ research, controversies, and the media. The survey was conducted in 2013 and 2014 using the Internet-based Expert Questionnaire on Cognitive Ability (EQCA). In the current study, we examined the background of the experts (e.g., nationality, gender, religion, and political orientation) and their positions on intelligence research, controversial issues, and the media. Most experts were male (83%) and from Western c...

Abstract Education has been found to have a positive influence on intelligence, but to be able to inform policy, it is important to analyse whether the observed association depends on the educational duration and intelligence prior to variations in educational attainment. Therefore, a longitudinal cohort study was conducted of all members of the Metropolit 1953 Danish Male Birth Cohort who were intelligence tested at age 12 and appeared before the Danish draft boards (N = 7389). A subpopulation ...

Abstract Numerous studies have found interactions between socioeconomic status (SES) and the heritability of cognitive ability in samples from the United States, with individuals from lower SES backgrounds showing decreased heritability compared to those reared in higher SES environments. However, nearly all published studies of the Scarr-Rowe interaction have been univariate and cross-sectional. In this study, we sought to maximize statistical power by fitting multivariate models of gene (G) x ...

Abstract The Wechsler scales are some of the most commonly used intelligence tests in research and practice. It is unknown whether different versions (i.e., WPPSI, WISC, and WAIS) or revisions (e.g., WISC-IV and WISC-V) of the Wechsler scales measure the same constructs. We tested the factorial invariance across six Wechsler scales (WPPSI-III, WPPSI-IV, WISC-IV, WISC-V, WAIS-III, and WAIS-IV) to investigate whether the constructs measured across these scales are the same. Factorial invariance wa...
