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.
