Morris a Department of Psycholow, Institute of Psychiatry, Psychology, and Neuroscience, King's College London, UK b MHR Biomedical Researh Centrefor Mental Health, South London and Maudsley NHS Foundation Tnast, London, UK CrossMark ARTICLE Article histoyy: INFO ABSTRACT While many studies have investigated the rise in IQ over time in various countries, the mesent study attempts to fill the gap in the Flynn effect literatule by considering data with various sample sizes, and different study designs, age groups and types of country. A Cross-Temporal Meta- Analysis (CTMA) technique was used to examine the relationship between mean IQ scores from the Raven's Progressive Matrices (RPM) and years of publication, moderated by age group and types ofcountry over a period of64 years ( 1950-2014). In all, 202,468 participants were included from 48 countries. We conclude that there is an obvious link between mean IQ scores and years Of publication. Importantly, interaction analyses indicate that both age group and types Of country moderate this relationship. 0 2014 Elsevier Inc.

Machine generated alternative text: In conclusion, the CTMA method was used in an attempt to produce a less biased estimate of the Flynn effect. With this method, a full range of age groups, countries and research methodologies (quasi-experimental design procedure, cohort study, and survey research) were all systematically evaluated, applied to the RPM tests. Over the course of decades, the gain in IQ score is generally robust and was found to be predominantly present in developing countries and more so for the SPM. The Flynn effect is strong enough to be showed in even small and non-representative samples as well as in the very young and older adults.
